OPTIMIZING FROG SURVEYS THROUGH OCCUPANCY MODELING: AN OVERVIEW OF ENVIRONMENTAL AND METHODOLOGICAL DETERMINANTS OF ANURAN DETECTABILITY Juliane Pereira-Ribeiro, Átilla Colombo Ferreguetti, Helena Godoy Bergallo, Carlos Frederico Duarte Rocha Oecologia Australis, 2026 Detecting the presence of a particular species in the environment is essential in studies aiming to assess the abundance and distribution of the species. Identifying the factors that affect the rate of species detectability is useful in designing monitoring programs and can lead to a more consistent study method. Here, we reviewed a set of factors that potentially influence the detection of frogs. We conducted an extensive literature review to identify key elements that affect frog detectability. Primarily, we focused on the environmental variables affecting frog species, with a brief consideration of the methodological aspects related to frog detection. We synthesized commonly used environmental and habitat variables, revealing recurring patterns and their connections with frog detectability. Additionally, we explored the methodological factors influencing frog detection and identified gaps in the current literature, proposing potential future research directions. Our findings highlight the significance of environmental factors such as temperature, precipitation, humidity, cloudiness, moon phase, and some habitat characteristics on frog detectability. Geographic biases in detectability studies limit our understanding, and expanding research into underexplored regions is crucial from a global perspective. In addition, incorporating specific environmental variables tailored to each species and habitat can enhance detection accuracy, improving our understanding of frog ecology and conservation. This review highlights the importance of accounting for detectability when surveying frogs and the need to consider all the factors influencing detectability.
How an invasive tree reshapes the forest floor and alters amphibian occupancy through direct and indirect effects Juliane Pereira-Ribeiro, Natália Vagmaker, Atilla Colombo Ferreguetti, Helena Godoy Bergallo, Carlos Frederico Duarte Rocha Biological Invasions, 2026 Biological invasions can alter forest ecosystems, reshaping microhabitats and disrupting the interactions that sustain native communities. Among these invaders, the jackfruit ( Artocarpus heterophyllus ) has spread widely across the Atlantic Forest, where its ecological impacts remain poorly understood. We investigated how jackfruit density influences forest-floor structure and the occupancy of three leaf-litter amphibian species. Using generalized linear mixed models, occupancy modelling, and structural equation models (SEM), we evaluated both direct and indirect pathways linking invasion intensity to key habitat attributes, including leaf-litter depth, arthropod density and diversity, and amphibian occurrence. Jackfruit density had strong negative effects on litter depth and arthropod density, indicating habitat simplification and resource loss. Occupancy models revealed contrasting responses among species, with generalists more tolerant to invaded conditions and forest specialists negatively affected by invasion intensity or dependent on litter-mediated pathways. The SEM confirmed that invasion effects propagate through structural and trophic mechanisms, altering microhabitat structure and prey availability. Our results demonstrate that invasive trees can restructure forest-floor ecosystems through cascading physical and biological changes. These invasion-driven filters promote biotic homogenization by favoring disturbance-tolerant species while disadvantaging microhabitat specialists. Recognizing and mitigating these indirect pathways is critical for conserving amphibian diversity and maintaining the ecological resilience of tropical forests under increasing invasion pressure.
Newly collected specimens of eastern Rhagomys (Rodentia, Sigmodontinae) reveal high morphological variation Filipe Souza-Gudinho, Helena Godoy Bergallo, Gisela Sobral Journal of Mammalogy, 2025 Rhagomys (Sigmodontinae) is an enigmatic rodent genus described almost 140 years ago, with few specimens collected up until recently, hindering knowledge of its morphology. Specimens collected during the last 2 decades have considerably changed the taxonomy of this genus. During this time, 3 new species were described, with the most recent from the Atlantic Forest. This species, Rhagomys jequitiba, occurs at the northernmost limit of the distribution of the type species, Rhagomys rufescens. With new specimens in hand, we revisited the morphology of R. rufescens and R. jequitiba, the eastern species of Rhagomys, adding to the growing body of literature. The present contribution describes external, cranial, and dental morphological traits for eastern Rhagomys, some for the first time. We improve understanding of morphological distinction between eastern Rhagomys species and securely assign the recently collected specimens to R. rufescens. In this process, we noted a morphologically distinct specimen within the range of the type species. This specimen represents only the second record for the state of Rio de Janeiro, following the holotype, and it differs from the latter in several traits. In general, this specimen exhibits distinctive traits compared to both R. rufescens and R. jequitiba, although sharing more similarities with R. rufescens. Moreover, we describe the distinct carotid pattern, which deviates slightly from all 3 conditions known for Sigmodontinae. The morphological variation described here is enough to warrant a thorough revisionary work for Rhagomys, including traits such as external, cranial, and dental features, but also additional features.
Integrating biodiversity into climate policy: From ecosystem services to food security in Brazil Carlos Eduardo V. Grelle, Cecília R. Vieira, Guarino R. Colli, Wiliam E. Magnusson, Adrian A. Garda, et al. Zoologia, 2025 Biodiversity and food security are often perceived as conflicting objectives, yet they are deeply interdependent through ecological processes. Biodiversity regulates soil quality, water, climate dynamics and ecological processes-such as pollination-thereby influencing food security, economic development, and resilience to climate risks. In Brazil, the conservation of ecosystems and pollination services exemplify how biodiversity underpins key agricultural commodities such as soy and coffee. Aligning biodiversity conservation with climate policy is therefore crucial, particularly in megadiverse countries that are major commodity producers. With COP30 taking place in Brazil, there is a unique opportunity to integrate biodiversity into global climate agendas, strengthen governance and legislation, and attract investment through sustainable frameworks. This perspective emphasizes that protecting biodiversity is not only an environmental priority but also a strategic pathway for food security, climate resilience, and sustainable economic development.
Camera trap surveys of Atlantic Forest mammals: A data set for analyses considering imperfect detection (2004–2020) Ingridi Camboim Franceschi, Rubem Augusto da Paixão Dornas, Isabel Salgueiro Lermen, Artur Vicente Pfeifer Coelho, Ademir Henrique Vilas Boas, et al. Ecology, 2024 Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity hotspot, especially for medium to large‐sized species. Here we present a data set from camera trap surveys of medium to large‐sized native mammals (>1 kg) across the Atlantic Forest. We compiled data from 5380 ground‐level camera trap deployments in 3046 locations, from 2004 to 2020, resulting in 43,068 records of 58 species. These data add to existing data sets of mammals in the Atlantic Forest by including dates of camera operation needed for analyses dealing with imperfect detection. We also included, when available, information on important predictors of detection, namely the camera brand and model, use of bait, and obstruction of camera viewshed that can be measured from example pictures at each camera location. Besides its application in studies on the patterns and mechanisms behind occupancy, relative abundance, richness, and detection, the data set presented here can be used to study species' daily activity patterns, activity levels, and spatiotemporal interactions between species. Moreover, data can be used combined with other data sources in the multiple and expanding uses of integrated population modeling. An R script is available to view summaries of the data set. We expect that this data set will be used to advance the knowledge of mammal assemblages and to inform evidence‐based solutions for the conservation of the Atlantic Forest.
