    O afastamento discente das práticas gímnicas: retrato de aulas de educação física no ensino fundamental II
    (Universidade Estadual Paulista (Unesp), 2024-03-27) Silva, Helen Maria Rodrigues da ; Bento-Soares, Daniela
    O afastamento discente de determinados conhecimentos é um problema comum na Educação Física escolar, principalmente ao se tratar de práticas corporais que extrapolam os esportes mais comumente tematizados na cultura escolar brasileira da atualidade. Essa problemática fica mais evidente a partir dos anos finais do ensino fundamental e pode causar impactos tanto na construção das aprendizagens por parte dos alunos e das alunas quanto na escolha das intervenções pedagógicas dos e das docentes. Este estudo tem como objetivo analisar se as experiências proporcionadas nas aulas de Educação Física aproximam ou distanciam os alunos e as alunas da Ginástica nos anos finais do ensino fundamental. Essa pesquisa tem caráter qualitativo e a construção dos dados se deu durante a realização das aulas de uma unidade didática sobre Ginástica para duas turmas de uma escola pública municipal de Campinas/SP. A pesquisa-ação foi escolhida como ferramenta metodológica, uma vez que os alunos e as alunas são sujeitos da pesquisa e, tal como a pesquisadora, se envolveram durante a sequência didática. Os dados foram analisados segundo o método de Análise de Conteúdo, considerando os princípios da pesquisa-ação, uma vez que as reflexões, diálogos e ações dos envolvidos e das envolvidas na pesquisa impactaram as experiências propostas. Os resultados apontam que apesar dos registros de afastamento encontrados, a participação discente foi superior, indicando que intervenções pedagógicas críticas que valorizam as relações sociais nas aulas de Ginástica contribuem para a identificação discente com o objeto de estudo.

    Efeitos da estrutura da paisagem sobre a chuva de sementes na Mata Atlântica
    (Universidade Estadual Paulista (Unesp), 2024-01-29) Gnonlonfoun, Fulbert Kodjovi Julie ; Ribeiro, Milton Cezar ; Monteiro, Erison Carlos dos Santos ; Instituto de Biociências
    O processo de fragmentação e de perdas de vegetação nativa causados pelas atividades antrópicas vêm impactando severamente a biodiversidade, o que pode estar afetando severamente diversos processos ecológicos e serviços ecossistêmicos associados. Desses processos, a chuva de sementes vem se destacando como o principal ponto de partida para a renovação natural da comunidade de plantas, contribuindo para a demografia, a variabilidade genética e a distribuição espaço-temporal das florestas tropicais. Entretanto, pouco se sabe sobre como as mudanças da paisagem afetam esse processo. Neste estudo, buscamos compreender como a composição e a configuração da paisagem afetam a riqueza e a abundância de sementes envolvidas no processo de chuva de sementes em fragmentos florestais na Mata Atlântica, considerando-se também as síndromes de dispersões dessas sementes. Para tanto, distribuímos coletores de sementes ao longo de gradientes da cobertura florestal, da quantidade de borda, da conectividade estrutural e da heterogeneidade florestal. Foram colocados 135 coletores de sementes em 27 paisagens, sendo 5 unidades amostrais por paisagem. Para desenvolvimento do estudo, foram realizadas as seguintes etapas: (i) coleta de chuva de sementes no campo; (ii) secagem, triagem e identificação das espécies em laboratório; (iii) tabulação dos dados; (iv) extração dos valores das métricas de paisagem em diferentes escalas espaciais (500 m, 1000 m, 1500 m, 2000 m e 5000 m). Foram realizadas amostragens durantes três meses consecutivos, entre os meses de junho e agosto 2022. Utilizamos uma abordagem de múltiplas hipóteses concorrentes com base no Critério de Informação de Akaike para a escolha do modelo mais parcimonioso. Foram coletados 38.449 diásporos em 245 espécies de 71 famílias. A riqueza e a abundância da comunidade de sementes, sendo elas zoocóricas ou anemo-autocóricas, responderam positivamente, com a heterogeneidade e com a quantidade de bordas, e negativamente, com a cobertura florestal e a conectividade. Esses resultados foram encontrados em diferentes escalas dependendo da métrica de paisagem considerada. Com isso, encontramos que a heterogeneidade e a quantidade de bordas, segundo os modelos analisados, podem ser fatores determinantes no processo de deposição de sementes, sendo importante em uma das etapas de restauração ecológicas. Nossos resultados podem contribuir para a elaboração de políticas públicas de restauração florestal em biomas como a Mata Atlântica.

    Transcranial direct current stimulation suggests not improving postural control during adapted tandem position in people with Parkinson’s disease: a pilot study
    (Elsevier, 2023-08-24) Legutke, Beatriz Regina ; Gobbi, Lilian Teresa Bucken ; Orcioli-Silva, Diego ; Santos, Paulo Cezar Rocha Dos ; Moraca, Gabriel Antonio Gazziero ; Vitório, Rodrigo ; Beretta, Victor Spiandor ; Universidade Estadual Paulista (Unesp)
    Background: Balance impairments in people with Parkinson's disease (PD) demonstrated mainly in challenging postural tasks, such as increased body oscillation may be attributed to the deficits in the brain structures functionality involved in postural control (e.g., motor cortex, midbrain, and brainstem). Although promising results, the effect of transcranial direct current stimulation (tDCS) on postural control in people with PD is unclear, especially in objective measures such as the center of pressure (CoP) parameters. Thus, we analyzed the effects of a single session of tDCS on the CoP parameters during the adapted tandem position in people with PD. Methods: Nineteen people with PD participated in this crossover, randomized, and double-blind study. Anodal tDCS was applied over the primary motor cortex in two conditions of stimulation (2 mA/active and sham) on two different days for 20 minutes immediately before the postural control evaluation. Participants remained standing in an adapted tandem position for the postural control assessment for 30 seconds (three trials). CoP parameters were acquired by a force plate. Results: No significant differences were demonstrated between stimulation conditions (p-value range = 0.15-0.89). Conclusions: Our results suggested that a single session of tDCS with 2 mA does not improve the postural control of people with PD during adapted tandem.

    Background: Studying the effects of smoking intensity is important to evaluate the risk of tobacco use on a range of illnesses, such as as sarcopenia among the elderly. Thus, this study aimed to analyze the effects of pack-years of cigarette smoking on the diaphragm muscle (DIAm) histopathology of postmortem samples. Methods: Subjects were divided into three groups: never-smoker (n = 46); less than 30 pack-years of smoking (n = 12); and more than 30 pack-years of smoking (n = 30). Diaphragm samples were stained with Picrosirius red and hematoxylin and eosin stain for general structure. Results: Participants with more than 30 pack-years of cigarette smoking had a significant increase in adipocytes, blood vessels and collagen deposit, as well as an increase in histopathological alterations. Conclusions: Pack-years of smoking was associated with DIAm injury. However, further clinicopathological studies are needed to confirm our findings.

    Amount and isolation of aquatic habitat drive anuran diversity in agricultural landscapes in the Brazilian Cerrado
    (2023-01-01) Silveira, Priscila ; Iop, Samanta ; dos Santos, Juliana Silveira ; Lima, Edgar L. ; Martello, Felipe ; Ribeiro, Milton Cezar ; Maciel, Natan M. ; Collevatti, Rosane G. ; Universidade Federal de Goiás (UFG) ; Universidade Federal Do Pampa ; Universidade Estadual Paulista (UNESP) ; Vale Technological Institute -Sustainable Development ; Universidade de Brasília (UnB)
    Context: Declining in biodiversity in the Anthropocene is mostly a result of habitat loss due to changes in the landscape. Objectives: Here, we address how landscape composition and configuration affect anuran diversity in agricultural landscapes in the Brazilian Cerrado ecoregion. Methods: We sampled 29 breeding sites during the rainy season using auditory census and visual encounters to record anuran species richness, and specialist, generalist and dominant species richness. For each sampling site, we estimated eight landscape metrics at five spatial scales. Results: We recorded 36 species from seven anuran families, 17 habitat specialist and 19 habitat generalists. We found that aquatic habitat cover (%) and number of aquatic patches played a positive effect on both total anuran richness and richness of dominant species. However, landscape compositional heterogeneity and aquatic habitat isolation negatively influenced community rarity, and abundance of habitat specialist species. In addition, more diverse anuran communities were found in areas where the amount and number of aquatic habitat patches were greater. Conclusions: Our results emphasize the importance of maintaining high amounts of waterbodies and high aquatic habitat connectivity across the landscapes. Moreover, rare species and habitat specialist species are sensitive to landscape composition and configuration, respectively. Therefore, water body amount and connectivity must be considered in conservation plans to mitigate anuran community loss in agricultural landscapes.

    Flowering phenology of species with similar flower colours in species-rich communities
    (2023-07-01) Camargo, Maria Gabriela Gutierrez ; Arista, Montserrat ; Lunau, Klaus ; Ortiz, Pedro Luis ; Stradic, Soizig Le ; Rocha, Nathália Miranda Walter Bretas ; Morellato, Leonor Patrícia Cerdeira ; Universidade Estadual Paulista (UNESP) ; Universidad de Sevilla ; Institute of Sensory Ecology
    Within a community, co-occurring plant species are expected to diverge in floral display or flowering phenology to decrease interspecific competition and thus increase intraspecific pollination. However, co-occurring species can also benefit from floral signal standardisation (similar colour signals among flowers of different species) because it facilitates pollinator attraction. Considering the interaction of flower colour display and flowering phenology, we investigated the visual similarity of rewarding flowers among species from highly diverse tropical and temperate vegetation types. For six groups of co-occurring, closely related bee-pollinated species with similar floral displays from Brazilian campo rupestre (51 species) and Spanish Mediterranean vegetation (30 species), we first investigated whether flower colours can be discriminated by bees based on colour locus distance in the bee vision hexagon. We then tested whether flowering phenology overlapped or was segregated. We found that within both vegetation regions, flower colour was generally not distinguishable within groups by bees. The small perceptual distance of colour loci in the bee visual space did not enable discrimination. The flowering periods of the Mediterranean species overlapped, while the Brazilian campo rupestre species tended to have segregated phenologies. Mediterranean species may benefit from the increased standardisation of signals displayed during the short flowering season, while the sequential flowering phenology of campo rupestre species may decrease interspecific competition and help maintain a recognizable signal for bees over time, favouring flower constancy. We concluded that the standardisation of the floral colour signal within these two species-rich plant communities is advantageous for most of the species studied, despite having different flowering phenologies.

    Electrocortical Dynamics of Usual Walking and the Planning to Step over Obstacles in Parkinson’s Disease
    (2023-05-01) Vitório, Rodrigo ; Lirani-Silva, Ellen ; Orcioli-Silva, Diego ; Beretta, Victor Spiandor ; Oliveira, Anderson Souza ; Gobbi, Lilian Teresa Bucken ; Universidade Estadual Paulista (UNESP) ; Northumbria University ; Newcastle University ; Aalborg University
    The neural correlates of locomotion impairments observed in people with Parkinson’s disease (PD) are not fully understood. We investigated whether people with PD present distinct brain electrocortical activity during usual walking and the approach phase of obstacle avoidance when compared to healthy individuals. Fifteen people with PD and fourteen older adults walked overground in two conditions: usual walking and obstacle crossing. Scalp electroencephalography (EEG) was recorded using a mobile 64-channel EEG system. Independent components were clustered using a k-means clustering algorithm. Outcome measures included absolute power in several frequency bands and alpha/beta ratio. During the usual walk, people with PD presented a greater alpha/beta ratio in the left sensorimotor cortex than healthy individuals. While approaching obstacles, both groups reduced alpha and beta power in the premotor and right sensorimotor cortices (balance demand) and increased gamma power in the primary visual cortex (visual demand). Only people with PD reduced alpha power and alpha/beta ratio in the left sensorimotor cortex when approaching obstacles. These findings suggest that PD affects the cortical control of usual walking, leading to a greater proportion of low-frequency (alpha) neuronal firing in the sensorimotor cortex. Moreover, the planning for obstacle avoidance changes the electrocortical dynamics associated with increased balance and visual demands. People with PD rely on increased sensorimotor integration to modulate locomotion.

    Trait interactions effects on tropical tree demography depend on the environmental context
    (2023-06-01) Kamimura, Vitor de A. ; Loiola, Priscilla de P. ; Carmona, Carlos P. ; Assis, Marco A. ; Joly, Carlos A. ; Santos, Flavio A.M. ; Vieira, Simone A. ; Alves, Luciana F. ; Martins, Valéria F. ; Ramos, Eliana ; Ramos, Rafael F. ; de Bello, Francesco ; Universidade Estadual Paulista (UNESP) ; Instituto Tecnológico Vale (ITV) ; Universidade Estadual de Campinas (UNICAMP) ; Universidade Federal de São Carlos (UFSCar) ; University of Tartu ; University of California ; IAC ; Instituto Nacional da Mata Atlântica (INMA) ; CIDE-CSIC-UV-GV ; University of South Bohemia
    Although functional traits are defined based on their impact on demographic parameters, trait-demography relationships are often reported as weak. These weak relationships might be due to disregarding trait interactions and environmental contexts, which should modulate species trait-demography relationships. We applied different models, including boosted regression tree (BRT) models, to investigate changes in the relationship between traits and demographic rates of tropical tree species in plots along an elevational gradient and among time intervals between censuses, analyzing the effect of a strong drought event. Based on a large dataset of 18,000 tree individuals from 133 common species, distributed among twelve 1-ha plots (habitats) in the Atlantic Forest (Brazil), we evaluated how trait interactions and the environmental context influence the demographic rates (growth, mortality, and recruitment). Functional traits, trait-trait, and trait-habitat interactions predicted demography with a good fit through either BRTs or linear mixed-models. Changes in growth rates were best related to size (diameter), and mortality rates to habitats, while changes in recruitment rates were best related to the specific leaf area. Moreover, the influence of traits differed among time intervals, and for demographic parameters, habitat affected growth and mortality by interacting with diameter. Here, we provide evidence that trait-demography relationships can be improved when considering the environmental context (space and time) and trait interactions to cope with the complexity of changes in the demography of tropical tree communities. Thus, to expand predictions of demography based on functional traits, we show that it is useful to fully incorporate the concept of multiple trait-fitness optima, resulting from trait interactions in different habitats and growth conditions.

    A systematic review of energy and mass fluxes, and biogeochemical processes in seasonally dry tropical forests and cactus ecosystems
    (2023-06-01) Jardim, Alexandre Maniçoba da Rosa Ferraz ; Morais, José Edson Florentino de ; Souza, Luciana Sandra Bastos de ; Lopes, Daniela de Carvalho ; Silva, Marcos Vinícius da ; Pandorfi, Héliton ; Oliveira-Júnior, José Francisco de ; Silva, Jhon Lennon Bezerra da ; Steidle Neto, Antonio José ; Morellato, Leonor Patricia Cerdeira ; de Lima, João L.M.P. ; Silva, Thieres George Freire da ; Federal Rural University of Pernambuco ; Federal University of São João del-Rei ; Federal University of Alagoas ; National Institute of the Semiarid (INSA) ; Universidade Estadual Paulista (UNESP) ; University of Coimbra
    Hostile climatic conditions, including high water deficit in the soil-atmosphere system characterize regions with arid and semi-arid climates. Local landscapes with climates of low rainfall and relative humidity, and high air temperature, such as regions of sub-humid, semi-arid, and arid zones, cover approximately 45.4% of the entire land surface of the planet, to which the biomes with dry forests occupy a total area of 1079 × 104 km2. Thus, this review aims to quantify the processes and changes in energy, water, and carbon fluxes and their interactions with the surfaces of terrestrial ecosystems of Caatinga and cacti in semi-arid environments. Studies report that forests in arid and semi-arid environments show resilience to local diversity, prominent in the interrelationship of species, which favors the survival of individuals with changes in the ecological niche. One of the main modifications in land use and land occupation in dryland landscapes is the implementation of agriculture. There is evidence that poor land use can negatively affect soil carbon stocks. Furthermore, carbon and energy fluxes in terrestrial ecosystems undergo significant changes with the removal of native vegetation. Therefore, the damage caused by deforestation can cause severe problems in the energy and carbon balance, compromising species' survival. Finally, we emphasize that crassulacean acid metabolism plants can be an alternative in places with serious environmental degradation problems.

    Forest amount determines the occupancy of the arboreal rodent Oecomys cleberi (Rodentia: Cricetidae) in Atlantic Forest fragmented landscapes
    (2023-01-01) Brito Dias, Viviane ; Martello, Felipe ; Regolin, André Luis ; Tomas, Walfrido Moraes ; Ribeiro, Milton Cezar ; Universidade Federal de Mato Grosso do Sul (UFMS) ; Universidade Estadual Paulista (UNESP) ; Instituto Tecnológico Vale ; Universidade Federal de Goiás (UFG) ; Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA)
    Oecomys cleberi is an arboreal rodent little known reagarding its natural history, distribution, and ecology. In this paper, we present new records of O. cleberi within a region of the Atlantic Forest, in a transition zone with Cerrado, in the northwestern state of São Paulo. We investigated the effects of the structure of fragmented landscapes on its occurrence at 40 sites in this region. We detected O. cleberi only in seasonal semideciduous forests and palm forests, but not in pastures, wetlands, and young reforestation. Our results indicated that its occurrence was determined by the amount of habitat within a 500 m radius landscape, and extremely low occupancy probabilities in landscapes with less than 25% forest cover (ψ < 0.3). Our results show the importance of the amount of habitat at the landscape scale for the occurrence of Oecomys cleberi, and point out that most of the landscapes in the study region presented low occupancy probabilities by this forest rodent. Although O. cleberi should not be considered as an Atlantic Forest species, it seems to be a resident species in ecotone areas with Cerrado, within the Atlantic Forest domain. Thus, conservation actions are necessary to preserve their populations in these regions.

    Chronic Adaptations to Eccentric Cycling Training: A Systematic Review and Meta-Analysis
    (2023-02-01) Barreto, Renan Vieira ; de Lima, Leonardo Coelho Rabello ; Borszcz, Fernando Klitzke ; de Lucas, Ricardo Dantas ; Denadai, Benedito Sérgio ; Universidade Estadual Paulista (UNESP) ; Universidade de São Paulo (USP) ; Universidade Federal de Santa Catarina (UFSC)
    This study aimed to investigate the effects of eccentric cycling (ECCCYC) training on performance, physiological, and morphological parameters in comparison to concentric cycling (CONCYC) training. Searches were conducted using PubMed, Embase, and ScienceDirect. Studies comparing the effect of ECCCYC and CONCYC training regimens on performance, physiological, and/or morphological parameters were included. Bayesian multilevel meta-analysis models were used to estimate the population’s mean difference between chronic responses from ECCCYC and CONCYC training protocols. Group levels and meta-regression were used to evaluate the specific effects of subjects and study characteristics. Fourteen studies were included in this review. The meta-analyses showed that ECCCYC training was more effective in increasing knee extensor strength, vastus lateralis fiber cross-sectional area, and six-minute walking distance compared to CONCYC. Moreover, ECCCYC was as effective as CONCYC in decreasing body fat percentage. CONCYC was more effective in increasing (Formula presented.) and peak power output attained during concentric incremental tests. However, group-level analyses revealed that ECCCYC was more effective than CONCYC in improving (Formula presented.) in patients with cardiopulmonary diseases. ECCCYC is a viable modality for exercise interventions aiming to improve parameters of muscle strength, hypertrophy, functional capacity, aerobic power, and body composition, with more advantages than CONCYC training in improving neuromuscular variables.

    Spatial distribution and temporal variation of tropical mountaintop vegetation through images obtained by drones
    (2023-02-10) Medeiros, Thaís Pereira de ; Morellato, Leonor Patrícia Cerdeira ; Silva, Thiago Sanna Freire ; Earth Observation and Geoinformatics Division (DIOTG) ; Universidade Estadual Paulista (UNESP) ; University of Stirling
    Modern UAS (Unmanned Aerial Vehicles) or just drones have emerged with the primary goal of producing maps and imagery with extremely high spatial resolution. The refined information provides a good opportunity to quantify the distribution of vegetation across heterogeneous landscapes, revealing an important strategy for biodiversity conservation. We investigate whether computer vision and machine learning techniques (Object-Based Image Analysis—OBIA method, associated with Random Forest classifier) are effective to classify heterogeneous vegetation arising from ultrahigh-resolution data generated by UAS images. We focus our fieldwork in a highly diverse, seasonally dry, complex mountaintop vegetation system, the campo rupestre or rupestrian grassland, located at Serra do Cipó, Espinhaço Range, Southeastern Brazil. According to our results, all classifications received general accuracy above 0.95, indicating that the methodological approach enabled the identification of subtle variations in species composition, the capture of detailed vegetation and landscape features, and the recognition of vegetation types’ phenophases. Therefore, our study demonstrated that the machine learning approach and combination between OBIA method and Random Forest classifier, generated extremely high accuracy classification, reducing the misclassified pixels, and providing valuable data for the classification of complex vegetation systems such as the campo rupestre mountaintop grassland.

    Multiple pre- and postzygotic components of reproductive isolation between two co-occurring Lysimachia species
    (2023-04-01) Jiménez-López, Francisco Javier ; Arista, Montserrat ; Talavera, María ; Cerdeira Morellato, Leonor Patrícia ; Pannell, John R. ; Viruel, Juan ; Ortiz Ballesteros, Pedro L. ; University of Seville ; Universidade Estadual Paulista (UNESP) ; University of Lausanne ; Kew
    Genetic divergence between species depends on reproductive isolation (RI) due to traits that reduce interspecific mating (prezygotic isolation) or are due to reduced hybrid fitness (postzygotic isolation). Previous research found that prezygotic barriers tend to be stronger than postzygotic barriers, but most studies are based on the evaluation of F1 hybrid fitness in early life cycle stages. We combined field and experimental data to determine the strength of 17 prezygotic and postzygotic reproductive barriers between two Lysimachia species that often co-occur and share pollinators. We assessed postzygotic barriers up to F2 hybrids and backcrosses. The two species showed near complete RI due to the cumulative effect of multiple barriers, with an uneven and asymmetric contribution to isolation. In allopatry, prezygotic barriers contributed more to reduce gene flow than postzygotic barriers, but their contributions were more similar in sympatry. The strength of postzygotic RI was up to three times lower for F1 progeny than for F2 or backcrossed progenies, and RI was only complete when late F1 stages and either F2 or backcrosses were accounted for. Our results thus suggest that the relative strength of postzygotic RI may be underestimated when its effects on late stages of the life cycle are disregarded.

    Occurrence of Gregarines (Protozoa: Apicomplexa) in the Neotropical Soldierless Ruptitermes spp. (Isoptera, Termitidae, Apicotermitinae)
    (2022-12-01) Janei, Vanelize ; Costa-Leonardo, Ana M. ; Universidade Estadual Paulista (UNESP)
    This is the first record of gregarine infection in the worker midgut of the Neotropical termites Ruptitermes pitan and Ruptitermes reconditus. Gregarines have already been described in the gut and hemocoel in workers of other termite species, and although these protozoa are not able to kill these insects, they may affect their fitness. In the present study, gregarines were only observed in the gut lumen or linked to the midgut wall of termite workers. Histological sections of the worker midgut of Ruptitermes spp. showed three phases of the gregarine life cycle with the same individual worker displayed up to 4 gamonts and 2 trophozoites.

    New Findings: What is the central question of this study? What are the physiological mechanisms underlying muscle fatigue and the increase in the O2 cost per unit of work during high-intensity exercise? What is the main finding and its importance? Muscle fatigue happens before, and does not explain, the (Formula presented.) slow component ((Formula presented.)), but they share the same origin. Muscle activation heterogeneity is associated with muscle fatigue and (Formula presented.). Knowing this may improve training prescriptions for healthy people leading to improved public health outcomes. Abstract: This study aimed to explain the (Formula presented.) slow component ((Formula presented.)) and muscle fatigue during cycling at different intensities. The muscle fatigue of 16 participants was determined through maximal isokinetic effort lasting 3 s during constant work rate bouts of moderate (MOD), heavy (HVY) and very heavy intensity (VHI) exercise. Breath-by-breath (Formula presented.), near-infrared spectroscopy signals and EMG activity were analysed (thigh muscles). (Formula presented.) was higher during VHI exercise (∼70% vs. ∼28% of (Formula presented.) reserve in HVY). The deoxygenated haemoglobin final value during VHI exercise was higher than during HVY and MOD exercise (∼90% of HHb physiological normalization, vs. ∼82% HVY and ∼45% MOD). The muscle fatigue was greater after VHI exercise (∼22% vs. HVY ∼5%). There was no muscle fatigue after MOD exercise. The greatest magnitude of muscle fatigue occurred within 2 min (VHI ∼17%; HVY ∼9%), after which it stabilized. No significant relationship between (Formula presented.) and muscle force production was observed. The τ of muscle (Formula presented.) was significantly related (R2 = 0.47) with torque decrease for VHI. Type I and II muscle fibre recruitment mainly in the rectus femoris moderately explained the muscle fatigue (R2 = 0.30 and 0.31, respectively) and the (Formula presented.) (R2 = 0.39 and 0.27, respectively). The (Formula presented.) is also partially explained by blood lactate accumulation (R2 = 0.42). In conclusion muscle fatigue and O2 cost seem to share the same physiological cause linked with a decrease in the muscle (Formula presented.) and a change in lactate accumulation. Muscle fatigue and (Formula presented.) are associated with muscle activation heterogeneity and metabolism of different muscles activated during cycling.

    The relationships between urbanization and bird functional traits across the streetscape
    (2023-04-01) Pena, João Carlos ; Ovaskainen, Otso ; MacGregor-Fors, Ian ; Teixeira, Camila Palhares ; Ribeiro, Milton Cezar ; Universidade Estadual Paulista (UNESP) ; Universidade Federal de Goiás (UFG) ; University of Helsinki ; Norwegian University of Science and Technology ; University of Jyväskylä ; Universidade Estadual de Minas Gerais ; Universidade Federal de Minas Gerais (UFMG)
    The urbanization process leads to changes in bird communities’ taxonomic and functional compositions. Highly urbanized areas generally exhibit a reduced number of bird species sharing few functional traits. However, most urban bird studies focused on vegetation patches in temperate cities. In this study, we investigate how urban environmental attributes – noise, height of buildings, and urban vegetation characteristics – modulate species occurrences and the distribution of functional traits across the streetscape of a tropical metropolis. We predicted diverse trait-environment relationships, but that highly urbanized contexts (e.g., noisy streets with tall buildings) would be mostly occupied b,y a lower number of species sharing generalist traits. We also predicted to observe streets with similar community composition (profiles) shaped by environmental conditions and interspecific interactions. We applied hierarchical modelling of species communities as a flexible framework for analysis of community data. We observed that, increased noise exposure and reduced green cover were negatively related with species richness due to their negative relationships with most species’ occurrences. On the other hand, larger number of trees and higher proportion of green cover presented mostly positive relationships with occurrences, and thus with species richness. Throughout our streetscape, community composition was highly heterogeneous and similar conditions led to similar profiles. For example, noisy streets may favor the presence of omnivorous and large-bodied species, while wooded streets may allow for the presence of smaller-bodied forest specialist species that exploit lower vegetation strata. Our results indicate that streetscapes may have the potential to harbor functionally and taxonomically diverse bird communities.

    Could middle- and long-distance running performance of well-trained athletes be best predicted by the same aerobic parameters?
    (2022-01-01) Denadai, Benedito Sérgio ; Greco, Camila Coelho ; Universidade Estadual Paulista (UNESP)
    The prediction of running performance at different competitive distances is a challenge, since it can be influenced by several physiological, morphological and biomechanical factors. In experienced male runners heterogeneous for maximal oxygen uptake (VO2max), endurance running performance can be well predicted by several key parameters of aerobic fitness such as VO2max and its respective velocity (vVO2max), running economy, blood lactate response to exercise, oxygen uptake kinetics and critical velocity. However, for a homogeneous group of well-trained endurance runners, the relationship between aerobic fitness parameters and endurance running performance seems to be influenced by the duration of the race (i.e., middle vs. long). Although middle-distance and ultramarathon runners present high aerobic fitness levels, there is no accumulating evidence showing that the aerobic key parameters influence both 800-m and ultramarathon performance in homogeneous group of well-trained runners. The vVO2max seems to be the best predictor of performance for 1500 m. For 3000 m, both vVO2max and blood lactate response to exercise are the main predictors of performance. Finally, for long distance events (5000 m, 10,000 m, marathon and ultramarathon), blood lactate response seems to be main predictor of performance. The different limiting/determinants factors and/or training-induced changes in aerobic parameters can help to explain this time- or distance-dependent pattern.

    Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time-consuming, especially in the highly diverse tropics. We aimed to provide a comprehensive repository of available flower–invertebrate interaction information for the Atlantic Forest, a South American tropical forest domain. Data were obtained from published works and “gray literature,” such as theses and dissertations, as well as self-reports by co-authors. The data set has ~18,000 interaction records forming 482 networks, each containing between one and 1061 interaction links. Each network was sampled for about 200 h or less, with few exceptions. A total of 641 plant genera within 136 different families and 39 orders were reported, with the most abundant and rich families being Asteraceae, Fabaceae, and Rubiaceae. Invertebrates interacting with these plants were all arthropods from 10 orders, 129 families, and 581 genera, comprising 2419 morphotypes (including 988 named species). Hymenoptera was the most abundant and diverse order, with at least six times more records than the second-ranked order (Lepidoptera). The complete data set shows Hymenoptera interacting with all plant orders and also shows Diptera, Lepidoptera, Coleoptera, and Hemiptera to be important nodes. Among plants, Asterales and Fabales had the highest number of interactions. The best sampled environment was forest (~8000 records), followed by pastures and crops. Savanna, grasslands, and urban environments (among others) were also reported, indicating a wide range of approaches dedicated to collecting flower–invertebrate interaction data in the Atlantic Forest domain. Nevertheless, most reported data were from forest understory or lower strata, indicating a knowledge gap about flower–invertebrate interactions at the canopy. Also, access to remote regions remains a limitation, generating sampling bias across the geographical range of the Atlantic Forest. Future studies in these continuous and hard-to-access forested areas will yield important new information regarding the interactions between flowers and invertebrates in the Atlantic Forest. There are no copyright restrictions on the data set. Please cite this data paper if the data are used in publications and teaching events.

    Does creatine supplementation affect recovery speed of impulse above critical torque?

    We previously reported that creatine supplementation improved intermittent isometric exercise performance by augmenting the total impulse performed above end-test torque (total IET′). However, our previous analyses did not enable mechanistic assessments. The objective of this study was to determine if creatine supplementation affected the IET′ speed of recovery. To achieve this objective, we retrospectively analyzed our data using the IET′ balance model to determine the time constant for the recovery of IET′ (τIET′). Sixteen men were randomly allocated into creatine (N = 8) or placebo (N = 8) groups. Prior to supplementation, participants performed quadriceps all-out exercise to determine end-test torque (ET) and IETʹ. Participants then performed quadriceps exercise at ET + 10% until task-failure before supplementation (Baseline), until task-failure after supplementation (Creatine or Placebo), and until the Baseline time after supplementation (Creatine- or Placebo-Isotime). τIET′ was faster than Baseline for Creatine (669 ± 98 vs 470 ± 66 s), but not Placebo (792 ± 166 vs 786 ± 161 s). The creatine-induced change in τIET′ was inversely correlated with the creatine-induced changes in both the rate of peripheral fatigue development and time to task-failure. τIET′ was inversely correlated with total IET′ and ET in all conditions, but creatine supplementation shifted this relationship such that τIET′ was faster for a given ET. Creatine supplementation, therefore, sped the recovery of IET′ during intermittent isometric exercise, which was inversely related to the improvement in exercise performance. These findings support that the improvement in exercise performance after creatine supplementation was, at least in part, specific to effects on the physiological mechanisms that determine the IET′ speed of recovery. HIGHLIGHTS Sixteen healthy participants were randomly allocated to creatine supplementation or placebo groups. Creatine supplementation accelerated the time constant for the recovery of IET′ (τIET′). The time constant for the recovery of IET′ (τIET′) was inversely related to both the rate of peripheral fatigue development and the time to task failure.

    TYPES OF COLLABORATIVE CONTINUOUS PROFESSIONAL DEVELOPMENT IN PHYSICAL EDUCATION: A DIALOGUE
    (2022-01-01) da Costa Filho, Roraima Alves ; Beni, Stephanie ; Aubin, Anne-Sophie ; Iaochite, Roberto Tadeu ; Fletcher, Tim ; Borges, Cecilia ; Universidade Estadual Paulista (UNESP) ; Norwegian School of Sport Sciences ; Université de Montréal ; Brock University
    This paper presents a dialogue between researchers from three collaborative continuous teacher professional development (CCPD) projects, each of which involved a different theoretical framework and research design. Discussing our unique contexts and the CCPD approaches we used enabled us to engage in an appreciative inquiry, in which we sought to acknowledge and build upon the strengths of each project and consider possibilities for the future. Findings highlight complexities of CCPD at different levels from the small-scale to the large, requiring thoughtful planning and implementation. Promoting intimacy, organizing schedules and timetables, and combining different modes of support are challenges that require contextualized responses. There is a need for CCPD facilitators and researchers to consider not only characteristics of effectiveness when choosing a CCPD approach, but also alignment with their own personal beliefs and theories of learning, as well as the beliefs, interests, and needs of teachers in their local contexts.
