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.

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.

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.

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.
Direct and indirect effects of landscape, forest patch and sampling site predictors on biotic interaction and seed process

Understanding the response of seed rain and seed bank to landscape changes is critical for maintaining the forest remnants integrity and the potential for natural regeneration in abandoned lands. Ecological research typically focuses on direct responses of these seed processes (i.e., seed rain and seed bank), without considering the relationship between them or the indirect impact of landscape changes on these processes via its influence on seed dispersers and seed predation. Here, we employ structuring equation modeling to quantify the direct and indirect effects of landscape structure and biotic interaction on bird-dispersed seed rain and seed banks in the Atlantic Forest. We conducted the study in 20 highly fragmented landscapes. Our study shows that lower seed disperser, seed rain and seed bank abundances, as well as higher seed predation rates will be found in a landscape context with higher percentage of pasture, isolated forest fragments and in matrices far from forest edge. The indirect effect of landscape change was related to the negative influence of seed predation rates on the seed bank abundance. Based on our results, we recommend managing the landscapes trying to increase the connectivity among the forest remnants and reduce the percentage of pasture, in order to improve the seed dispersal and decrease the seed predation rates. In addition, it is essential that management plans evaluate these processes as a whole to accelerate forest recovery due to the complex relationships associated with seed rain and seed bank. Graphical abstract: Conceptual model highlighting the spatial context effects on biotic interaction (seed dispersers and predation) and seed processes (seed rain and seed bank). A At sampling local level, the seed rain and the seed predators have the opposite response to the distance to the forest edge. In addition, the seed predators vary according to the type of land cover/use. The seed predation inside the forest is lower than the outside. The highest predation was in coffee plantations. B At a landscape level, the percentage of pasture in the surrounding landscape has an inverse effect on seed predation, seed bank, and seed rain, being positive for seed predation, but negative for the seed bank and seed rain. Otherwise, the percentage of coffee plantations in the landscape has a positive effect on seed dispersers. [Figure not available: see fulltext.]

Species interactions can propagate disturbances across space via direct and indirect effects, potentially connecting species at a global scale. However, ecological and biogeographic boundaries may mitigate this spread by demarcating the limits of ecological networks. We tested whether large-scale ecological boundaries (ecoregions and biomes) and human disturbance gradients increase dissimilarity among plant-frugivore networks, while accounting for background spatial and elevational gradients and differences in network sampling. We assessed network dissimilarity patterns over a broad spatial scale, using 196 quantitative avian frugivory networks (encompassing 1496 plant and 1004 bird species) distributed across 67 ecoregions, 11 biomes, and 6 continents. We show that dissimilarities in species and interaction composition, but not network structure, are greater across ecoregion and biome boundaries and along different levels of human disturbance. Our findings indicate that biogeographic boundaries delineate the world’s biodiversity of interactions and likely contribute to mitigating the propagation of disturbances at large spatial scales.
Landscape structure shapes the diversity of plant reproductive traits in agricultural landscapes in the Brazilian Cerrado

The replacement of native vegetation by crops and pasturelands compromises the functional diversity of plants and negatively influence ecosystem functions such as pollination and seed dispersal. Here, we investigate the effects of landscape structure on the diversity of functional traits in agricultural landscapes in the Brazilian Cerrado. We sampled the woody plant community in 49 sites in forests and savannas, and analyzed the density and richness of pollination and seed dispersal syndromes. We performed model selection using Akaike Information Criterion to test whether landscape variables such as habitat amount, percentage of agriculture and pasture, patch and edge densities, and compositional heterogeneity at different spatial scales influence the density and richness of woody plant functional traits related to seed dispersal and pollination syndromes. The amount of forest and patch density were the landscape predictors that explained most of the diversity of plant functional traits. The amount of agricultural and savanna as well as edge density and landscape heterogeneity also affected functional traits. Our results suggest that habitat amount and configuration in the landscapes drive the diversity of functional traits, pointing that maintaining habitats within Cerrado agricultural landscapes is determinant for the plant's functional traits diversity. Furthermore, a heterogeneous mosaic may favor the density or richness of plants pollinated by insects and hummingbirds. The continuous loss and fragmentation of habitats may lead to loss of ecological functions compromising the provision of ecosystems services in agricultural landscapes in the Cerrado ecoregion.
Plant–frugivore interactions across the Caribbean islands: Modularity, invader complexes and the importance of generalist species
(2022-11-01) Vollstädt, Maximilian G. R. ; Galetti, Mauro ; Kaiser-Bunbury, Christopher N. ; Simmons, Benno I. ; Gonçalves, Fernando ; Morales-Pérez, Alcides L. ; Navarro, Luis ; Tarazona-Tubens, Fabio L. ; Schubert, Spencer ; Carlo, Tomas ; Salazar, Jackeline ; Faife-Cabrera, Michel ; Strong, Allan ; Madden, Hannah ; Mitchell, Adam ; Dalsgaard, Bo ; University of Copenhagen ; University of Miami ; Universidade Estadual Paulista (UNESP) ; University of Exeter ; Para La Naturaleza ; Universidad de Vigo ; Old Dominion University ; The Pennsylvania State University ; Universidad Autónoma de Santo Domingo (UASD) ; Grupo Jaragua Inc. ; Universidad Central “Marta Abreu” de Las Villas ; Aiken Center ; Caribbean Netherlands Science Institute (CNSI) ; and Utrecht University ; Sint Eustatius National Parks
Aim: Mutualistic interactions between plants and animals are fundamental for the maintenance of natural communities and the ecosystem services they provide. However, particularly in human-dominated island ecosystems, introduced species may alter mutualistic interactions. Based on an extensive dataset of plant–frugivore interactions, we mapped and analysed a meta-network across the Caribbean archipelago. Specifically, we searched for subcommunity structure (modularity) and identified the types of species facilitating the integration of introduced species in the Caribbean meta-network. Location: Caribbean archipelago (Lucayan archipelago, Greater Antilles, Lesser Antilles). Methods: We reviewed published scientific literature, unpublished theses and other nonpeer-reviewed sources to compile an extensive dataset of plant–frugivore interactions. We visualized spatial patterns and conducted a modularity analysis of the cross-island meta-network. We also examined which species were most likely to interact with introduced species: (1) endemic, nonendemic native or introduced species, and (2) generalized or specialized species. Results: We reported 3060 records of interactions between 486 plant and 178 frugivore species. The Caribbean meta-network was organized in 13 modules, driven by a combination of functional or taxonomic (modules dominated by certain groups of frugivores) and biogeographical (island-specific modules) mechanisms. Few introduced species or interaction pairs were shared across islands, suggesting little homogenization of the plant–frugivore meta-network at the regional scale. However, we found evidence of “invader complexes,” as introduced frugivores were more likely to interact with introduced plants than expected at random. Moreover, we found generalist species more likely to interact with introduced species than were specialized species. Main conclusions: These results demonstrate that generalist species and “invader complexes” may facilitate the incorporation of introduced species into plant–frugivore communities. Despite the influx of introduced species, the meta-network was structured into modules related to biogeographical and functional or taxonomic affinities. These findings reveal how introduced species become an integral part of mutualistic systems on tropical islands.
Frugivore distributions are associated with plant dispersal syndrome diversity in the Caribbean archipelagos

Aim: Many plants rely on interactions with frugivores for dispersal, suggesting that animal communities may affect plant occupancy and diversity. However, the contribution of these interaction-led biotic variables on plant diversity is poorly understood, especially in archipelagic hotspots such as the Caribbean. In island ecosystems, biogeographic theories suggest that island configurations drive colonization-extinction dynamics, while macroecology argues for the importance of climatic drivers of biodiversity. Within this context, we examine how frugivore-driven biotic factors are associated with fruiting plant species richness in relation to abiotic (climatic and geologic) and island configuration characteristics. Location: Caribbean archipelagos. Methods: We compiled a review of the diversity and distributions of 6039 plants and 326 vertebrate frugivores across 105 islands within the Caribbean. We then identified characteristics related to plant-frugivore interactions and assigned each species as having either abiotic (wind, water, etc.) or zoochoric (frugivory-dependent) dispersal syndromes. We related plant richness and dispersal syndromes to the regional diversity and characteristics of frugivorous animals, abiotic environments and island configuration characteristics through stepwise multivariate regression with generalized linear models and model selection. Results: We found that 44.6% of Caribbean plants are dispersed through frugivory (endozoochory). Frugivore-related characteristics, namely accumulated body mass of island bird assemblages, were the best predictors of the diversity of seed dispersal syndromes. To a lesser degree, reptile richness and soil variety were also considered important predictors for zoochoric plant distribution, while island areas affected abiotically-dispersed plants. Main conclusion: We found that biotic characteristics of frugivore communities are important predictors of plant diversity in the Caribbean archipelagos. However, this may also be influenced by climate and colonization history. Given the importance of biotic metrics in explaining plant diversity, we suggest that fruit-frugivore interactions are important components of island biogeography and that frugivorous communities should be accounted for plant biodiversity predictions and forecast models.

The Atlantic Forest of South America hosts one of the world's most diverse and threatened tropical forest biota. After five centuries of European human expansion, most Atlantic Forest landscapes are archipelagos of small forest fragments surrounded by open-habitat matrices. In this chapter, we describe the causes and consequences of large-scale defaunation in the Atlantic Forest of South America. We identify and quantify the magnitude of the main anthropogenic drivers of defaunation and stimulate a debate on how to revert the loss of fauna to restore biodiversity and ecosystem functions and services. The magnitude of the impact of defaunation in the Atlantic Forest is hard to estimate, but we can predict that, at large scale, habitat loss, fragmentation, and degradation are the most common threats to terrestrial populations. Other threats vary in importance according to the taxonomic group. In general, apex predators, other carnivores, large-bodied mammals, and large herbivores were among the most defaunated functional groups and the loss of these animals has also a strong impact on the ecosystem services. Given the extent of the consequences of defaunation in the Atlantic Forest, mitigation strategies are imperative. Habitat restoration would clearly be effective in building space for defaunation mitigation but reversing the pervasive defaunation that occurred in the Atlantic Forest is by no means a straightforward task. Nonetheless, it will be fundamental to assure the persistence of the biodiversity in the Atlantic Forest remnants.

Bark production of generalist and specialist species across savannas and forests in the Cerrado
(2023-04-28) Chiminazzo, Marco Antonio ; Bombo, Aline Bertolosi ; Charles-Dominique, Tristan ; Fidelis, Alessandra ; Universidade Estadual Paulista (UNESP) ; IRD ; Sorbonne University
BACKGROUND AND AIMS: Bark allows species to survive fire, protecting their inner tissues and allowing new branches to resprout from aerial buds. Thus, bark production is likely to be selected with aerial bud protection in fire-prone ecosystems. By considering the coexistence of fire-prone and fire-free ecosystems, in addition to the different impacts of flames on different growth forms, in this study we tested whether: (1) species from areas with higher fire frequencies have a faster bark production; (2) bark growth rate differs between trees and shrubs; (3) generalists adjust their bark production according to their environment (fire-prone or fire-free ecosystems); and (4) fast bark production results in better aerial bud protection. METHODS: We sampled two different types of forests and savannas in the Cerrado and registered every woody individual with height between 1.5 and 3 m tall (directly exposed to the flames). For the 123 species registered, we sampled three different individuals in each vegetation type where the species occurred to assess their bark production and aerial bud protection. We then checked, for each species, their preferred habitat (savanna and forest specialists or generalists) and their predominant growth form. KEY RESULTS: A minimal threshold of 0.13 mm per growth unit of bark production differentiated woody communities from savannas and forests. Shrubs and trees did not differ in terms of bark growth rate, despite being exposed to the flames in a different manner. Generalist species in savannas were able to produce bark above the threshold. However, when these species were in forests they produced bark below the threshold. Finally, a higher bark growth rate accounted for a better aerial bud protection. CONCLUSIONS: Generalist species are likely to be capable of displaying plasticity in their bark production, which could be important for their success in contrasting ecosystems. The relationship between aerial bud protection and bark growth rate suggests that bark production plays an important role in protecting the dormant buds, in addition to being selected in fire-prone ecosystems.
How did the animal come to cross the road? Drawing insights on animal movement from existing roadkill data and expert knowledge
(2023-01-01) Cassimiro, Isabella M. F. ; Ribeiro, Milton Cezar ; Assis, Julia C. ; Universidade Estadual Paulista (UNESP) ; Wageningen University and Research
Context: Animal movement through the landscape is essential to several ecological processes, assuring genetic flow, reproductive success and population dynamics. In fragmented landscapes, species change their movement patterns according to their sensitivity to landscape cover and configuration. Increased landscape habitat loss and fragmentation affects resource distribution and habitat availability, compelling species to move more frequently through anthropized matrices. Objectives: Our aim was to provide a new prospect for what is known about animal movement through the landscape anthropogenic matrix in the Atlantic Forest biodiversity hotspot, by analyzing the potential movement distances of several mammal, bird, reptile, and amphibian species. Methods: We used recorded roadkills within the Brazilian Atlantic Forest as a source of information of species’ occurrence. We assumed the euclidean distance from the roadkill spot to the nearest forest fragment as the potential movement distance by different species through the anthropogenic matrix. Experts’ classification of species’ forest dependence degree, and animal movement information from the literature survey was used to analyze the variation in potential animal movement distance in these matrices. Results: We analyzed 90 species, the majority of them being non-forest dependent (n = 64; 71%). The potential movement distances ranged from 0 to > 1500 m, and forest-dependent species presented lower mean distances (between 772 and 978 m) than non-forest dependent species (between 673 and 1015 m). The literature survey resulted in 44 articles regarding animal movement in the matrix, referred only to 22 species. No articles were found for 20 species, mainly reptiles and amphibians. Conclusions: By comparing these values to the average distance between forest remnants in the Atlantic Forest, we expect that the distance to be traveled through the matrix to reach forest fragments may be restrictive, mainly for species with higher degree of forest dependence. Despite being descriptive, our results provide important insights on animal movement through the matrix, especially for less studied species, such as amphibians and reptiles.

Improving coexistence between humans and large predators is one of the foremost issues for the survival of large carnivores, especially in the Neotropics, where conflicts for retaliation are still frequent. This problem was increased due to the expansion of agricultural areas, settlements, roads, and the loss of natural habitats. Therefore, a key component in the long-term conservation of carnivores is to reduce animal-human conflicts. We aimed to assess multi-scale habitat selection models, exploring specificities in the selection for each sex and variation for the circadian period. We found that jaguars live in real landscapes of fear with high human and livestock density, where the perception of risk related to humans governed the selection of their resources. However, depending on the sex of individuals and the circadian period, jaguars positively selected some anthropic structures, such as areas of crops and human settlements. This selection suggested an aptitude to use various human-dominated structures and indicated jaguars could locally perceive risks in different ways, depending of sex and day period. Unexpectedly, jaguars presented attraction to roads, sexual or circadian related, regardless of the natural environments. Our results demonstrate that male and female jaguars could use some anthropic features differently in the distinct circadian periods. In addition, we conclude that the knowledge of the habitat selection for jaguars is a crucial component to the structure of the landscape of coexistence of this species and can give us efficient guidance to better comprehend the behavior through different scales of selection and through different periods of the day. Finally, our results show fundamental observations on the movement plasticity of this species for the construction of conservation plans focusing on the coexistence in different landscapes of the Neotropics dominated by humans.

The response of woody plants to fire is influenced by the timing and spatial distribution of their growth modules relative to the flames. Predictions suggest changes in fire regimes for different vegetation types, emphasizing the need to understand which plant species will thrive and the underlying mechanisms enabling their survival. Considering the modularity of plants over time and space is essential. As plants develop through growth modules' production, their modules can gain increased protection against flames. Additionally, new modules produced farther from the direct impact of the flames may survive by being exposed only to the flame plume. Importantly, the survival capacity of modules during a fire is strongly dependent on trait expression (such as bark production and bud protection) and heat transference from one module to another. Different ecosystems evolved and are maintained by fire, with their vegetation hosting species with a wide diversity of persistence strategies allowing them to insulate their body and resprout new branches after fire disturbance. Changes in fire regime are predicted due to climate change, either by promoting more frequent and/or severe fires or by reducing the number of fire events due to the limitation of fuel load. Predicting the future of fire-driven ecosystems is a complex task as species' survival depends on many factors that vary in space and time. Since plants are constantly experiencing new environments as they grow through meristem development, woody plant modularity, modules morpho-physiological aspects and their integration should be considered when investigating species strategies in fire-prone ecosystems: according to their position and their tissue composition, plants' modules experience fire differently and will contribute differently to other modules and the whole plant survival, with consequences cascading over the overall vegetation structure. Growth modules may hold the key to understanding how fast plants can get protected from fire, ultimately helping us to predict which species will persist across changing fire regimes. We present an empirical example showing how different fire-return intervals translate into distinct pressures on the timing, protection and location of modules, and discuss how these can translate into modifications in the vegetation structure due to climate change.

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.
Spatial and social organization of the burrowing rodent Clyomys laticeps (Thomas, 1909)

Burrowing rodents display diverse patterns of social organization, ranging from solitary to group living. Differences in social organization are often inferred from patterns of space use, particularly differences in the degree to which individual home ranges overlap. Here, we characterize patterns of space use in a poorly studied species of burrow-dwelling echimyid rodent, the Broad-headed Spiny Rat (Clyomys laticeps). Specifically, we use radiotelemetry studies of a free-living population in Parque Estadual da Serra de Caldas Novas (Goias, Brazil) to evaluate previous, apparently contradictory reports suggesting that this species is both solitary and social. A total of 20 adult (12 females, 8 males) C. laticeps were monitored via telemetry during two consecutive cycles of annual wet and dry seasons. The resulting data indicate that although overlap of individual home ranges was common, co-occurrence of adults in time and space was rare and was limited to male-female pairs, a pattern that is most consistent with a solitary lifestyle in which individuals occupy distinct burrow systems. Neither sex nor season affected spatial overlap; this outcome is consistent with evidence suggesting that reproduction in this species occurs throughout the year. Although home ranges for males were larger than those for females, areas occupied by both males and females overlapped with multiple opposite-sex individuals, making it difficult to determine from spatial data whether the study population was polygynous or polygynandrous. While genetic data are needed to characterize fully the mating system of these animals, our analyses provide the first detailed information regarding spatial relationships in C. laticeps, thereby allowing more accurate placement of this species within a larger, comparative behavioral framework and facilitating efforts to identify factors contributing to social diversity among burrow-dwelling rodents.
First record of jaguar (Panthera onca) and potential prey species in Sierra de Quila, Jalisco, Mexico

The jaguar (Panthera onca) is considered a keystone species for neotropical ecosystems. Jaguar records in natural protected areas (NPAs) are important to manage and maintain the long-term occupancy of the species in a region. The objectives of this study are to report the first jaguar records in the Sierra de Quila, Jalisco, Mexico, and to report observations of potential prey items. Between February 2018 and January 2019, 24 camera traps were placed for 180 days during 3 seasons, with a total capture effort of 3216 trap nights. Four hundred and two independent records were obtained from 17 species of wild mammals and 3 domestic species. In February, 2 photographs of a jaguar were recorded at a single sampling point in the Sierra de Quila Flora and Fauna Protection Area. They correspond to the same individual, presumably an adult male. Subsequently, in July, a photograph of a jaguar was recorded at another sampling point. These records represent a 69-km extension of the known jaguar distribution, to the center of Jalisco, and increase the number of mammal species known for this NPA.
Impact of image acquisition lag-time on monitoring short-term postfire spectral dynamics in tropical savannas: the Campos Amazonicos Fire Experiment
(Spie-soc Photo-optical Instrumentation Engineers, 2022-07-01) Alves, Daniel Borini ; Fidelis, Alessandra ; Perez-Cabello, Fernando ; Alvarado, Swanni T. ; Conciani, Dhemerson Estevao ; Cambraia, Bruno Contursi ; Pires da Silveira, Antonio Laffayete ; Silva, Thiago Sanna Freire ; Universidade Estadual Paulista (UNESP) ; Univ Zaragoza ; Univ Estadual Maranhao ; Amazon Environm Res Inst ; Inst Chico Mendes Conservacao Biodiversidade ; Univ Fed Rondonia ; Univ Stirling
The use of optical remote sensing to monitor short-term postfire dynamics in rapidly recovering ecosystems is a complex task, requiring strong spectral separability and high temporal resolution. Thus, characterizing the effects of temporal lag in image acquisitions in relation to fire occurrence is of fundamental importance to improve our understanding of how fire-related environmental and ecological processes are connected to multitemporal spectral information. We used a harmonized series of Sentinel-2A/2B and Landsat-7/8 images paired with a fire experiment specifically designed for remote sensing assessment to evaluate short-term spectral responses of fire in tropical savannas. Our experimental design included strategic geolocation of experimental plots and separate prescribed burnings during the early- and mid-dry seasons. The M-statistic was used to assess spectral separability between burned and control treatments, and the temporal stability was assessed using fire scar latency, a custom statistic adapted to capture scar spectral responses over time. Finally, linear regressions were fitted to explore the association between consumed fuel load and spectral indices. The variation of normalized burn ratio and mid-infrared bispectral index indices stood out with the highest separability (M-statistic > 3) in both treatments and moderate-high association with consumed fuel load (R-2 > 0.54). We observed that burned areas spectral sensitivity depends not only on timing of image acquisition but also on fire season and their interactions with land surface phenology. Our characterization provides a solid benchmark for future experimental assessments of fire spectral responses and provides new insights for improving fire monitoring algorithms.
