Wildfire and Drought Alter the Ecology of Jaguars and Co‐Occurring Mammals in the World's Largest WetlandNARA Subscribed
Climate change‐driven disturbances are reshaping ecosystems worldwide with profound implications for biodiversity. We leveraged a long‐term dataset and a natural before‐after‐control‐impact experimental framework to evaluate the impacts of wildfire and concurrent drought on jaguars and the terrestrial mammal community in northern Pantanal. Using camera traps and jaguar scats collected before, during, and after a large wildfire...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
A Latitudinal Cline in the Taxonomic Structure of Eelgrass Epifaunal Communities is Associated With Plant Genetic DiversityNARA Subscribed
Aim Biogenic structural complexity increases mobile animal richness and abundance at local, regional and global scales, yet animal taxa vary in their response to complexity. When these taxa also vary functionally, habitat structures favouring certain taxa may have consequences for ecosystem function. We characterised global patterns of epifaunal invertebrates in eelgrass ( Zostera marina ) beds that varied in structural and ge...
Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time intervals of up to 78 years at 141 sites across mountain summits, forests, and lowland grasslands in Europe. We found, albeit with relatively small effect sizes, displacements of smaller‐ by larger‐ranged specie...
Extensive aquatic subsidies lead to territorial breakdown and high density of an apex predatorNARA Subscribed
Energetic subsidies between terrestrial and aquatic ecosystems can strongly influence food webs and population dynamics. Our objective was to study how aquatic subsidies affected jaguar ( Panthera onca ) diet, sociality, and population density in a seasonally flooded protected area in the Brazilian Pantanal. The diet ( n = 138 scats) was dominated by fish (46%) and aquatic reptiles (55%), representing the first jaguar populati...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
Ancient DNA suggests modern wolves trace their origin to a Late Pleistocene expansion from BeringiaNARA Subscribed
Grey wolves ( Canis lupus ) are one of the few large terrestrial carnivores that have maintained a wide geographical distribution across the Northern Hemisphere throughout the Pleistocene and Holocene. Recent genetic studies have suggested that, despite this continuous presence, major demographic changes occurred in wolf populations between the Late Pleistocene and early Holocene, and that extant wolves trace their ancestry to...
