The case for studying tadpole autecology, with comments on strategies to study other small, fast-moving animals in nature
(2023-01-01) Annibale, Fabiane S.; Wassersug, Richard J.; Rossa-Feres, Denise de C. [UNESP]; Nomura, Fausto; Brasileiro, Cinthia A.; Sabbag, Ariadne F. [UNESP]; Zeng, Yu; Phillips, Jackson R.; Universidade Virtual do Estado de São Paulo; University of British Columbia; Universidade Estadual Paulista (UNESP); Universidade Federal de Goiás (UFG); Universidade Federal de São Paulo (UNIFESP); Chapman University; Berkeley; Utah State University
Two of the most fundamental questions in tadpole biology, also applicable to most small, under-studied organisms are: (1) ‘Why are they built the way they are?’ and (2) ‘Why do they live where they do?’ Regrettably, despite significant progress in most aspects of tadpole biology, the answers to these questions are not much better now than they were in the last century. We propose that an autecological approach, that is the careful observation of individuals and how they interact with the environment, is a potential path towards a fuller understanding of tadpole ecomorphology and evolution. We also discuss why more attention should be given to studying atypical tadpoles from atypical environments, such as torrential streams, water-filled cavities of terrestrial plants and wet rock surfaces neighbouring streams. Granted, tadpoles are rare in these settings, but in those unusual habitats the physical environments can be well described and characterized. In contrast, the more common ponds where tadpoles are found are typically too structurally complex to be easily delineated. This makes it difficult to know exactly what individual tadpoles are doing and what environmental parameters they are responding to. Our overall thesis is that to understand tadpoles we must see exactly what they are doing, where they are doing it, and how they are doing it. This takes work, but we suggest it is feasible and could greatly advance our understanding of how anuran larvae have evolved. The same strategies for studying tadpoles that we encourage here can be applied to the study of many other small and fast-moving animals.
Tropical headwater streams and the role of non-native species on fish assemblage’s diversity
(2023-01-01) Santos, Bruno R. B.; Teresa, Fabrício B.; Borges, Pedro P.; Casatti, Lilian [UNESP]; Tejerina-Garro, Francisco L.; Pompeu, Paulo S.; Benedito, Evanilde; Carvalho, Fernando R.; Cetra, Mauricio; Dias, Murilo S.; Súarez, Yzel R.; Santos, Thiago; Brejão, Gabriel; Carvalho, Rodrigo A.; Universidade Estadual de Goiás; Universidade Estadual Paulista (UNESP); Pontifícia Universidade Católica de Goiás; UniEVANGÉLICA; Universidade Federal de Lavras (UFLA); Universidade Estadual de Maringá (UEM); Universidade Federal de Mato Grosso do Sul (UFMS); Universidade Federal de São Carlos (UFSCar); Universidade de Brasília (UnB); Universidade Estadual do Mato Grosso do Sul; Universidade Federal dos Vales do Jequitinhonha e Mucuri; Lancaster University
Non-native species cause several impacts on freshwater biodiversity, but studies focusing on the Neotropical stream’s biota are still incipient. We used a data set of 586 headwater stream’s fish assemblages from the Brazilian Upper Paraná ecoregion to test whether the presence/absence of non-native species affect: species richness (S), functional diversity (MPD) and taxonomic diversity (Δ+). We compared diversity patterns of fish assemblages formed only by native species against those of assemblages formed by native and non-native species (Scenario 1); then, we removed non-native species from their original assemblages and recalculated their diversity values to compare them with those of fish assemblages formed only by native species again (Scenario 2). We also investigated: (1) whether non-native’s fish assemblages are associated with land use, topographic and watercourse connectivity variables; (2) fish ecological traits-environment relationship. In Scenario 1, S was higher in assemblages with the presence of non-native species, while in Scenario 2, both S and MPD were higher in assemblages where non-native species were removed. Non-native species were not directly related to land use, topographic or connectivity variables and most of them had a similar response to the environment when compared with native species. Findings show that non-native fish species are related to high-rich assemblages in headwaters, and they increase species richness and the functional redundancy of assemblages, decreasing functional diversity. Moreover, in most cases, native and non-native species seem to respond similarly to the environmental influence on their occurrence.

Data obtained by direct observation of organisms in their natural habitats can provide valuable contributions regarding intra-and inter-specific interactions, as well as spatial distribution and trophic relationships. However, relatively few such data are available for the Neotropical ichthyofauna relative to the great species diversity of this region. We present data on the ichthyofauna in karst environments of the Serra da Bodoquena, Upper Paraguay River basin regarding their categorization into functional trophic groups. We used direct observations that focused on the most frequent feeding tactics and their spatial (vertical and horizontal) distribution in the channel. We observed 83 fish species in 17 functional trophic groups. The greatest species richness was concentrated in the Characidae and Loricariidae in the categories Diurnal Backwater Drift Feeders and Grazers, respectively. Regarding horizontal depth stratification, we found a positive relationship between the association of small fish with the shallow marginal habitats. This work represents a contribution to a region known for its high tourist potential and to the important diversity of the entire ichthyofauna of the Upper Paraguay basin region that requires proper conservation strategies for sustaining these species.
Factors affecting the transferability of bioindicators based on stream fish assemblages
(2023-07-10) Sousa, Victoria; Dala-Corte, Renato Bolson; Benedito, Evanilde; Brejão, Gabriel Lourenço [UNESP]; Carvalho, Fernando Rogério; Casatti, Lilian [UNESP]; Cetra, Mauricio; Pompeu, Paulo Santos; Súarez, Yzel Rondon; Tejerina-Garro, Francisco Leonardo; Borges, Pedro Paulino; Teresa, Fabrício Barreto; Universidade Federal de Goiás (UFG); Universidade Estadual de Goiás; Universidade Estadual de Maringá (UEM); Universidade Estadual Paulista (UNESP); Universidade Federal de Mato Grosso do Sul (UFMS); Universidade Federal de São Carlos (UFSCar); Universidade Federal de Lavras (UFLA); Universidade Estadual do Mato Grosso do Sul; Pontifícia Universidade Católica de Goiás; UniEVANGÉLICA
The development of multimetric indices (MMIs) to measure the biotic condition of aquatic habitats is based on metrics derived from biological assemblages. Considering fish assemblages, the inconsistencies in metrics responses outside of the places where they were developed limit MMI transferability and applicability to other locations, requiring local calibration. The factors behind the low transferability of these MMIs are still poorly understood. We investigated how environmental dissimilarity and spatial distance influence the transferability of metrics generated from local stream fish assemblages to other regions. We also tested whether functional and taxonomic metrics respond differently to the spatial distance. We used data from 239 fish assemblages from streams distributed across a Brazilian, the upper Parana basin and characterized each site according to the level of anthropogenic disturbance at the landscape scale using an Anthropogenic Pressure Index (API). We divided the upper Parana basin into sub-basins and used two of them to create template response models of the metrics in relation to the API. We used these response models to predict the responses outside the template sub-basins. Our response variable representing a metric of transferability was the absolute difference between metric's predicted and observed value for each site (prediction error). We thus modeled the prediction error in relation to the predictor variables that were i) the environmental dissimilarity between each site with the average of the sites from template sub-basins (climatic, topographic and soil type variables) and ii) the spatial distance (overland and watercourse distance) between each site and the center of the template sub-basin. We found that errors in metric predictions were associated with both environmental dissimilarity and spatial distance. Furthermore, functional and taxonomic metrics responded equally to spatial distance. These results indicate the need for local calibration of metrics when developing MMIs, especially if the protocols already available come from distant and environmentally dissimilar places.
EMPORAL DISTRIBUTION, REPRODUCTIVE SYNCHRONY, AND MATING PATTERNS OF THE EXPLOSIVE BREEDER FROG DERMATONOTUS MUELLERI (ANURA: MICROHYLIDAE)
(2022-09-03) Nomura, Fausto; De Carvalho, Fernando Rogério; Rossaferes, Denise De Cerqueira [UNESP]; Universidade Federal de Goiás (UFG); Universidade Federal de Mato Grosso do Sul (UFMS); Universidade Estadual Paulista (UNESP)
The knowledge about natural history of a species is fundamental for the proposition of theories in population, community, and behavioral ecology. Dermatonotus muelleri (Boettger, 1885) is one of the several Neotropical anuran species that still lacks basic information. These frogs are widely distributed in South America and present many peculiar morphological features, such as a reduced head size and a tongue morphology that suggests a specialized diet in ants and termites. In this study, we describe the reproductive ecology of D. muelleri, with special attention to the mechanisms that regulates (i) the reproductive synchrony between males and females, (ii) the operational sex ratio (OSR), and (iii) if size is a good predictor of pairs formation (assortative mating). We found that D. muelleri aggregates in short periods of reproductive activity (one to five consecutive nights) to reproduce. During the reproductive events, males and females arrive at the breeding sites in synchrony, using environmental (temperature and pluviosity) and biotic (termite reproductive swarms and male calling) cues. Also, there is a high population density (1,079 ± 816 individuals, n = 11 reproductive events), with a biased OSR toward the number of males. The intense malemale competition prevents any female choice, and the call function is related more to reduction of predation costs to females. We did not find size assortative mating in D. muelleri. The lack of size assortative mating may be a consequence of different pressure selection of males and females. While females where selected to have larger body size and offspring production, at the cost of reproductive lifespan, males are subject to an intense malemale competition which prevents the expression of female preferences.
Spatial non-stationarity in the distribution of fish species richness of tropical streams
(2023-04-01) Vieira, Thiago Bernardi; Sánchez-Botero, Jorge Iván; Garcez, Danielle Sequeira; Lima, Sergio Maia Queiroz; Pavanelli, Carla Simone; Casatti, Lilian [UNESP]; Smith, Welber Senteio; Benedito, Evanilde; Mazzoni, Rosana; Pompeu, Paulo Santos; Agostinho, Carlos Sérgio; de Assis Montag, Luciano Fogaça; Zuanon, Jansen; De Podestà Uchôa de Aquino, Pedro; Cetra, Mauricio; Pena, Simone Almeida; Alexandre, Rafaela Jemely Rodrigues; Oliveira, Andressa Sasha Quevedo Alves; Tejerina-Garro, Francisco Leonardo; Duboc, Luiz Fernando; Pérez-Mayorga, María Angélica [UNESP]; Brejão, Gabriel Lourenço [UNESP]; Mateussi, Nadayca Thayane Bonani [UNESP]; Leitão, Rafael Pereira; De Marco Júnior, Paulo; Universidade Federal do Pará (UFPA); Universidade Federal do Ceará; Universidade Federal do Rio Grande do Norte; Universidade Estadual de Maringá (UEM); Universidade Estadual Paulista (UNESP); Universidade Paulista; Universidade do Estado do Rio de Janeiro (UERJ); Universidade Federal de Lavras (UFLA); Universidade Federal de Tocantins; Universidade Federal do Para; Instituto Nacional de Pesquisas da Amazônia; Universidade de Brasılia; Universidade Federal de São Carlos (UFSCar); Pontifícia Universidade Católica de Goiás; Universidade Federal do Espírito Santo (UFES); Universidade Federal de Minas Gerais (UFMG); Universidade Federal de Goiás (UFG)
Diversity gradients are observed for various groups of organisms. For fishes in streams, the water-energy, productivity, and temporal heterogeneity hypotheses can explain richness patterns. The relationship between species diversity and the variables that represent these hypotheses is generally linear and stationary, that is, the effect of each of those variables is constant throughout a geographically defined area. But the assumption of spatial stationarity has not yet been tested on a great number of diversity gradients. Therefore, we aimed to quantify the spatial stationarity in the relationships between fish species richness in small stream (653 streams) located throughout Brazil, and the water-energy, productivity, and temporal heterogeneity hypotheses using a geographically weighted regression—GWR. There was a conspicuous absence of spatial stationarity in fish species richness. Furthermore, water-energy dynamics represented a possible metabolic restriction acting on the community structuring of fish species richness in streams. This mechanism separated the fish fauna into two regions: (i) The Amazonian region, characterized by a stable climate and populations that are less resistant to climatic variation; and (ii) The central region, featured by greater ranges of temperature and fish populations that are resistant to climatic variation.
Sternal exocrine glands in Neotropical Social Wasps
(2020-11-07) da Silva, Marjorie [UNESP]; Noll, Fernando Barbosa [UNESP]; Billen, Johan; Universidade Estadual Paulista (UNESP); KU Leuven-Bélgica
A great diversity of exocrine glands is found in social insects. The main social function of exocrine glands is the production of pheromones, which are related to the maintenance of social organization of the colony, as interactions of dominance, maintenance of queen status, recruitment for food, search for nesting sites, defense, and reproductive behaviors, among other aspects. The exocrine glands can be classified into two types (class 1 and class 3) according to their structural arrangement. Some of them are common to all social insects, occurring in males and females (e.g., mandibular and salivary glands). Others are characteristic of a taxon, as the van der Vecht and Richards glands, found only in vespids of the Vespidae family. An overview about the structure, location, and, whenever possible, function of the exocrine glands of Neotropical social wasps is presented here. Future studies considering large and more detailed morphological analyses, together with information on the chemical aspects of the produced secretions, are desirable for a broader understanding of the function of the pheromones produced by the exocrine glands in the social wasps.
Castes and polymorphisms in Neotropical Social Wasps
(2020-11-07) da Silva, Marjorie [UNESP]; Mateus, Sidnei; Noll, Fernando Barbosa [UNESP]; Universidade Estadual Paulista (UNESP); Universidade de São Paulo (USP)
Neotropical social wasps have a set of chimeric characteristics that make them unique and difficult to fit into current theories on the evolution of social behavior (Noll and Wenzel, Biol J Linn Soc 93: 509-22, 2008). Among them, the presence of more than one functional queen (polygyny), absence of strong morphological differentiation, and flexibility between casts result in relaxation of ovarian control and breeding opportunity for workers (West-Eberhard, Science 200: 441-3, 1978; Noll, Sociobiology 60: 347-54, 2013). Adding to these particularities, the Polistinae wasps, especially those belonging to the Epiponini, reached a great radiation and evolutionary success in the Neotropical region due to the unique mode of social organization: colony foundation by a swarm (Jeanne, The swarm-founding Polistinae. In: Ross KG, Matthews RW (eds) The social biology of wasps. Cornell University Press, Ithaca, pp 191-231, 1991), where several or many reproductive females (queens) tolerate each other laying eggs. This chapter deals in general with aspects of the complex caste delimitation, the division of labor in the colony, the recruitment and foraging, and the lack of colony in social wasps, with emphasis on swarm founders.
Redescription of Neocarus platensis Silvestri, 1905 (Acari: Opilioacaridae) and a new species from the syntype series
(2023-01-20) De Araújo, Marcel Santos; Di Palma, Antonella; Feres, Reinaldo José Fazzio [UNESP]; Penteado-Dias, Angelica Maria; Universidade Federal de São Carlos (UFSCar); University of Foggia; Universidade Estadual Paulista (UNESP)
Neocarus platensis is redescribed from part of the syntype series collected in Argentina and lectotype specimens are designated. The remaining syntype material from Uruguay represents a new species, herein named Neocarus paraplatensis sp. nov. Taxonomic problems within the Opilioacaridae are discussed in light of a comparative morphological discussion including setae quantity variation.

Amazonian lowland rainforests epitomize, as few other biomes, the terrestrial and freshwater biological diversity of our planet. We provide here a comprehensive description of the larval anurans of Central Amazonia, and their natural history. We base our analyses on fieldwork conducted in six terra-firme rainforest and two várzea floodplain sites during ∼60 months between 1990 and 2013, complemented with an examination of museum specimens and a review of published literature. Ninety-nine species of anurans are known to occur in Central Amazonia. Of these, 84 species (85%) have a free-swimming exotrophic larva, six species (6%) have a terrestrial endotrophic larva, one species has a terrestrial exotrophic larva (1%) and another seven species (7%) have direct development of eggs into froglets. The life cycle of one species (1%) remains unknown. We formally describe and illustrate the larval stage of 68 species (i.e., 75% of the species with a known larval stage), five of them previously unkown and nineteen never described for Central Amazonia. We compile, review and update information on species natural history including reproductive modes, habitat use, phenology, and species interactions including diet, predators, competitors and parasites. Finally, we assessed the ecomorphological diversity in the region by the application of a system inspired in Altig & Johnston (1989), later updated by Altig & McDiarmid (1999), which recognizes tadpole guilds based on a combination of morphological and natural history data. Basic scientific information presented in this monograph provide the essential background for further studies on the ecological and evolutionary forces shaping anuran Amazonian assemblages, and their conservation.

Sperm length variation is linked to sexual ornamentation in male paper wasps
(2022-01-01) de Souza, André R.; Santos, Eduardo F. [UNESP]; Baptista, Camila F.; Dias, Glenda; Nascimento, Fábio S.; Lino-Neto, José; Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP); Universidade Federal de Viçosa (UFV)
Diversification of sperm design is a common feature in animals. Considerable intra-individual variation has been detected even in species whose males produce a monomorphic sperm. The evolutionary forces that shape the variation in the gross morphology of these gametic cells are still not completely understood. Previous studies suggest that the intra-individual variation in sperm size reduces as a result of post-copulatory sexual selection. To our knowledge, for the first time, we provide evidence here that pre-copulatory sexual selection can also play a role. By studying the Neotropical paper wasp, Polistes simillimus, a monandrous species, we found reduced variation in sperm length in males bearing sexual ornamentation preferred by females. Besides, the female spermatheca contains a less variable sperm compared to that in the male seminal vesicles. Thus, the scope of selection, acting on this sperm trait, seems broader than previously acknowledged.
The tadpoles of the neotropical Scinax catharinae group (Anura, Hylidae): Ecomorphology and descriptions of two new forms
(2016-03-01) Pezzuti, Tiago Leite; Fernandes, Igor Rodrigues; Leite, Felipe Sá Fortes; De Sousa, Carlos Eduardo [UNESP]; Garcia, Paulo Christiano Anchietta; Rossa-Feres, Denise [UNESP]; Universidade Federal de Minas Gerais (UFMG); Universidade Federal de Viçosa (UFV); Universidade Estadual Paulista (UNESP)
Herein we provide novel data on the external morphological features and natural history of the tadpoles of Scinax canastrensis and Scinax carnevallii, two poorly known tree frog species occurring in southeastern Brazil. Both species share characteristics with all other species of the Scinax catharinae group, including oral discs not emarginated with the posterior margin concave when closed, many submarginal papillae laterally, circular nostrils, and vent tubes reaching the ventral fin margin. Landmark-based geometric morphometrics applied to 16 species of the S. catharinae group indicate that their tadpoles have substantial variation in body shape, yet with some overlap among species. Although the lentic/lotic habitat categorization was not sufficient for explaining the complex patterns of morphospace occupancy by tadpoles of S. catharinae group, some well-established ecomorphological relationships were recovered, such as that for suctorial and pond-type guilds. Moreover, the morphological diversity in shape may also reflect interspecific variation in microhabitat use, other contemporary factors (e.g., other abiotic habitat components and/or biological interactions) and evolutionary relationships.
Flat mites (Tenuipalpidae) from Bahia state, Northeastern Brazil- a checklist including new records and an illustrated key to species
(Acarologia-universite Paul Valery, 2023-05-24) Nascimento, Renata S.; Souza, Kaelem S.; Melo, Elisangela A. S. F.; Tassi, Aline D.; Castro, Elizeu B. [UNESP]; Navia, Denise; Mendonca, Renata S. de; Ochoa, Ronald; Oliveira, Anibal R.; Univ Estadual Santa Cruz UESC; Univ Florida; Universidade Estadual Paulista (UNESP); Univ Montpellier; Universidade de Brasília (UnB); Agr Res Serv ARS
Tenuipalpidae (Trombidiformes: Tetranychoidea) is an economically important family of plant-feeding mites. The family has approximately 1,100 described species in 41 genera with worldwide distribution. Currently, 40 species of Tenuipalpidae have been recorded from Brazil, and prior to this study only 11 were known from Bahia state. Five new species records are presented here for Bahia, making a total of 16 species now known from the state. Brevipalpus is considered the most important genus due to their association with, and ability to transmit, devastating plant viruses. Some diseases caused by viruses transmitted by Brevipalpus mites (VTBs) have already been recorded in the state of Bahia, such as the Passion fruit green spot virus and citrus leprosis. This paper presents a checklist of tenuipalpids reported from the state of Bahia in Brazil, including new records and an illustrated identification key to the species.
Comparison of yellow pan, Malaise, and ethanolic traps for sampling parasitoid Vespoidea and other Hymenoptera in a semideciduous forest fragment of the Brazilian Atlantic Rainforest
(Alma Mater Studiorum, Univ Bologna, 2022-06-01) Wenceslau, Jose F. C. [UNESP]; Santos, Eduardo F. [UNESP]; Carnimeo, Fernando H. [UNESP]; Noll, Fernando B. [UNESP]; Universidade Estadual Paulista (UNESP)
Parasitoid wasps within the Vespoidea superfamily have been chronically under surveyed, thanks to the bigger attention given to the social species within that group or to the other parasitoids within the megadiverse Parasitica infraorder. To address that, we test a new sampling technique for the capture of parasitoid Vespoidea and other Hymenoptera in comparison to other two well stablished designs. Between the consecutive dry and wet seasons of 2014-2015 we placed sets of Malaise (MT), yellow pan (YPT) and ethanolic (ET) traps in a fragment of semideciduous Brazilian Atlantic Rainforest. We hypothesised that MT is the most efficient method for sampling Hymenoptera families and lower taxa of Vespoidea, while YPT and ET would be more efficient in attracting specific taxa, given their characteristic luring mechanisms. We calculated taxa accumulation curves to evaluate expected richness. Average Taxonomic Distinctiveness (Delta(+)) was used as the continuous dependent variable in two-way ANOVAs. Faunal similarity was inspected through nonmetric multidimensional scaling (NMDS). All tests were performed taking season and trap design as explanatory variables. MT was the most efficient in sampling total richness and Delta(+) of Hymenoptera and Vespoidea lower taxa. It captured all 39 families recorded in the present study and 60 out of the 73 Vespoidea lower taxa. YPT tended to lure Diapriidae, Dryinidae, Ponerinae and Myrmicinae ants and a few taxa of Pompilidae and Mutillidae, proving its efficiency in sampling wingless and short-flying hymenopterans as well as the predators and parasites of other non-grass feeding insects. ET, although successful in estimating Hymenoptera Delta(+), did not have a sufficient capture rate to give a precise estimate of total richness. It attracted, however, the social wasps Polybia jurinei Saussure and Synoeca surinama (L.), species traditionally captured by active search. Synthesis and Applications: MT is confirmed as the most efficient capture method for Hymenoptera sampling and is recommended when a survey of the whole community is intended. ET was not successful in capturing any parasitoid Vespoidea as hypothesised but, as well as the YPT, it could be used as an alternative to active searches when the taxa listed above are the focus of the survey. These results provide a better understanding of passive capture methods for Hymenoptera sampling and can be considered in future surveys aiming to investigate their diversity, distribution and improve their conservation.
Taxonomic review of the elampine cuckoo wasps from northeastern Brazil (Hymenoptera: Chrysididae), with the description of three new species
(Magnolia Press, 2022-11-25) Lucena, Daercio A. A. [UNESP]; Santos-Neto, Pedro E.; Zanella, Fernando C.; Almeida, Eduardo A. B. [UNESP]; Universidade de São Paulo (USP); Universidade Federal de Pernambuco (UFPE); Univ Fed Integracao Latino Amer UNILA; Universidade Estadual Paulista (UNESP)
The diversity of the Elampini cuckoo wasps in northeastern Brazil is reviewed. Three new species are described: Hedychrum oxente Lucena & Zanella sp. nov., Holopyga lunae Lucena sp. nov., and Muesebeckidium clemensi Lucena & Zanella sp. nov. A lectotype is designated for Holopyga piliventris Ducke, 1907 and herein illustrated. Elampus aequinoctialis Ducke, 1901 is restored as a valid species (previously synonymized with Elampus gayi Spinola, 1851) and diagnosed. Holophris huberi (Ducke, 1901) and Muesebeckidium clemensi sp. nov. represent the first records of both genera to northeastern Brazil. New records along with up-to-date distributional maps are discussed, and an identification key to the species of Holopyga from northeastern Brazil is provided. The total diversity of Elampini recorded for northeastern Brazil is now represented by the following eight species: Elampus aequinoctialis Ducke, 1901, Exallopyga guatemalensis (Cameron, 1888), Hedychrum oxente Lucena & Zanella sp. nov., Holophris huberi (Ducke, 1901), Holopyga iheringi du Buysson, 1901, H. lunae Lucena sp. nov., H. piliventris Ducke, 1907, and Muesebeckidium clemensi Lucena & Zanella sp. nov.
First record of Tenuipalpuspanici de Leon (Acari: Tenuipalpidae) in South America, with new morphological data and a discussion on the ontogeny of setae
(Systematic & Applied Acarology Soc London, Natural History Museum, 2022-10-01) Nascimento, Renata S.; Castro, Elizeu B. [UNESP]; Tassi, Aline D.; Ochoa, Ronald; Oliveira, Anibal R.; Univ Estadual Santa Cruz UESC; Universidade Estadual Paulista (UNESP); Universidade de São Paulo (USP); ARS
Tenuipalpus panici De Leon was originally described from female specimens collected on Panicum maximum Jacq. (Poaceae) from South of Baranquetas, Puerto Rico. In this paper, we redescribe the female of T. panici based on the holotype and on specimens newly collected in Brazil. It is the first record of the species in South America. Females, nymphs and larvae were collected on Paspalum notatum Flugge (Poaceae); males were absent. New morphological data for both females and immatures (e.g., dorsal and ventral ornamentation, gnathosomal, idiosomal, leg chaetotaxy, and measurements) and a discussion on the patterns of ontogenetic setal additions for all the immature stages are provided. Tenuipalpus panici is the only species of the genus known with two setae appearing on femur IV in the protonymph and successive stages.

Disentangling the multiple drivers of tadpole metacommunity structure in different ecoregions and multiple spatial scales
(2022-01-01) Pelinson, Rodolfo Mei [UNESP]; Rossa-Feres, Denise de Cerqueira [UNESP]; Garey, Michel Varajão; Universidade Estadual Paulista (UNESP); Universidade Federal da Integração Latino-Americana (UNILA)
We evaluated the relative importance of environmental and spatial variables in structuring tadpole metacommunities at three hierarchical spatial scales in two ecoregions of the Atlantic Forest. Tadpole communities were generally more spatially structured at larger spatial scales. Environmental filtering processes seemed to be equally important at both large and small scales, however, spatially structured environmental variables were more important at larger scales, whereas non-spatially structured ones were more important at smaller scales. The importance of local environmental filters was also greater in the ecoregion that exhibits harsher environmental conditions, such as higher intensity of land-use patterns and dryer climate. This may indicate a greater role for stochastic assembly processes in more benign environments. Species co-occurrence patterns at the larger spatial scale mostly indicated biogeographical differences between the two ecoregions in a Clementsian structure, exhibiting two clear groups of species composition. Co-occurrence patterns at the smallest spatial scale were coherent only when strong environment gradients such as canopy cover were present. However, at the intermediate spatial scale the metacommunities became consistently non-coherent suggesting that species may be responding to processes acting at different spatial scales.
