Em 2020, incêndios em vegetação queimaram aproximadamente 40 mil hectares e mataram 17 milhões de vertebrados. Esse evento catastrófico, caracterizado pelo comportamento extremo do fogo facilitado pela combinação matéria orgânica acumulada seca prolongada, evidenciou tanto a vulnerabilidade ecossistema pantaneiro frente aos sazonais quanto necessidade um entendimento mais amplo sobre seus possíveis efeitos na biodiversidade local nas dinâmicas ecossistêmicas. Este estudo explora dos mamíferos Pantanal vegetação, com foco características ecológicas sua relação o distribuição espacial das espécies. Foram revisados 2.868 estudos publicados desde 1938, abarcando cinco ordens mamíferos: Artiodactyla, Carnivora, Didelphimorphia, Rodentia Perissodactyla. As análises revelaram aumento significativo pesquisas ao fogo, particularmente carnívoros, partir ano 2000. estudadas incluem preferência habitat, tamanho corpóreo dieta, enquanto outros aspectos críticos para entender sensibilidade receberam menos atenção, como época reprodutiva, mobilidade, social corpóreo. Nossos resultados ressaltaram uma sazonalidade marcada ocorrência 2019-2020 especialização habitat entre as espécies Pantanal, sobreposição preocupante os desses anos várias espécies, que pode influenciar declínio da abundância distribuição. Os apontam esforços conservação imediatos, alvo habitat-chave abordagens manejo direcionadas mitigar impactos fauna, geograficamente restritas.

Abstract Increasingly frequent megafires are dramatically altering landscapes and critical habitats around the world. Across western United States, have become an almost annual occurrence, but implication of these fires for conservation native wildlife remains relatively unknown. Woodland savannas among world's most biodiverse ecosystems provide important food structural resources to a variety wildlife, they threatened by megafires. Despite this, great majority fire impact studies only been conducted in coniferous forests. Understanding resistance resilience assemblages following extreme perturbations can help inform future management interventions that limit biodiversity loss due megafire. We assessed woodland savanna mammal community short‐term impacts megafire using camera trap data collected before, during, after fire. Specifically, we utilized 5‐year set (2016–2020) from Hopland Research Extension Center examine 2018 Mendocino Complex Fire, California's largest recorded wildfire at time, on distributions eight observed species. used multispecies occupancy model quantify effects species' space use, assess species size diet groups, create robust estimates fire's diversity across time. Megafire had negative effect detection certain species, overall, showed high disturbance returned site use levels comparable unburned sites end study period. Following megafire, richness was higher burned areas retained canopy cover relative with low cover. Fire prevents large‐scale is providing refugia vulnerable immediately oak woodlands, likely other mixed‐forest landscapes.

Context A comprehensive understanding of movements and space use can underpin the effective management threatened species. GPS dataloggers collect large amounts high-quality movement data, recent advances in statistical approaches allow for robust estimates home range size to be generated. Until recently, technological practical constraints have generally restricted collection data via larger However, reductions weight now this technology applied smaller Aims The aim study was describe patterns a nationally vulnerable, native Australian ground-dwelling mammal, long-nosed potoroo (Potorous tridactylus), south-west Victoria, mainland Australia. Methods We attached 40 potoroos between 2020 2022 estimated using dynamic Brownian Bridge models. evaluated influence physiological factors such as body mass sex on described overlap within sexes. Key results Mean sizes were 13.73 ha (95% CI: 10.9–16.6) 6.67 5.49–7.85) males females respectively. Home scaled with but not females, ranges largely overlapping – although there some evidence intrasexual spatial partitioning core areas females. Conclusions Ours is first application species, our are over twice other reported Long-nosed may across than previously predicted Implications This knowledge used optimise populations before after fire key threatening process Our highlights value integrating estimators when describing ecology population.

Extreme environmental disturbances such as fires are predicted to increase in severity and extent with climate change. To better understand ecological impacts of unprecedented scales disturbance, empirical monitoring data urgently needed. Broadscale passive networks camera traps or acoustic recorders an increasingly popular approach for monitoring. Australia's 2019–2020 Black Summer megafires burned over 8 million hectares, a network across eastern New South Wales provided Before-After-Control-Impact opportunity examine this event on biodiversity. We evaluated severe fire mammals using dynamic occupancy models characterise the colonisation unoccupied sites, extinction occupied sites between 2018 2021. used Generalized Linear Mixed Models identify species traits correlated detections, predicting widely distributed broadest habitat breadths would be most frequently detected, threatened least detected. Our analyses limited insight into fires. Forty-two mammal were detected 'definite' but approximately 91 % records attributed just eight species. Extinction trends four species, one was trend. Endangered less likely than Vulnerable Least Concern Decreasing costs sensors artificial intelligence will encourage networks. However, our results caution that large volumes sensor not necessarily overcome many shortcomings Bespoke designs, progressive analyses, method refinement remain important ensure greatest value can derived from data.

Movement plays a key role in allowing animal species to adapt sudden environmental shifts. Anthropogenic climate and land use change have accelerated the frequency of some these extreme disturbances, including megafire. These megafires dramatically alter ecosystems challenge capacity several adjust rapidly changing landscape. Ungulates their movement behaviors play central ecosystem functions fire-prone around world. Previous work has shown behavioral plasticity is an important mechanism underlying whether large ungulates are able recent changes environments effectively. may respond immediate effects megafire by adjusting behavior, but how responses persist or over time following disturbance poorly understood. We examined ecologically dominant ungulate with strong site fidelity, Columbian black-tailed deer (Odocoileus hemionus columbianus), adjusted its behavior response altered landscape To do so, we collected GPS data from 21 individual female course year compare home range size used resource selection (RSFs) hidden Markov models (HMMs) assess habitat selection. found compelling evidence adaptive across Deer avoided exposed severely burned areas that lack forage could be riskier for predation immediately megafire, they later select at higher severities, potentially take advantage enhanced forage. results suggest despite high can navigate landscapes track rapid shifts encounter risk predators availability. This successful adjustment help facilitate resilience broader ecological scales.
