Data from: Remotely sensed data informs red list evaluations and conservation priorities in southeast Asia

Binbin V. Li, Alice C. Hughs, Clinton N. Jenkins, Natalia Ocampo-Peñuela, Stuart L. Pimm & Alice C. Hughes
The IUCN Red List has assessed the global distributions of the majority of the world’s amphibians, birds and mammals. Yet these assessments lack explicit reference to widely available, remotely-sensed data that can sensibly inform a species’ risk of extinction. Our first goal is to add additional quantitative data to the existing standardised process that IUCN employs. Secondly, we ask: do our results suggest species of concern—those at considerably greater risk than hitherto appreciated? Thirdly, these...

Data from: Patterns of vertebrate diversity and protection in Brazil

Clinton N. Jenkins, Maria Alice S. Alves, Alexandre Uezu & Mariana M. Vale
Most conservation decisions take place at national or finer spatial scales. Providing useful information at such decision-making scales is essential for guiding the practice of conservation. Brazil is one of the world’s megadiverse countries, and consequently decisions about conservation in the country have a disproportionate impact on the survival of global biodiversity. For three groups of terrestrial vertebrates (birds, mammals, and amphibians), we examined geographic patterns of diversity and protection in Brazil, including that of...

Highways are a threat for giant armadillos (Priodontes maximus) that underpasses can mitigate

Aureo Banhos, Bruno Fontes, Debora Yogui, Mario Henrique Alves, Natália Carneiro Ardente, Renata Valls, Lucas Mendes Barreto, Lucas Damásio, Átilla Colombo Ferreguetti, Andréa Siqueira Carvalho, Vitor Roberto Schettino, Alexandre Rosa Dos Santos, Helena Godoy Bergallo, Ana Carolina Srbek-Araujo, Patricia Medici, Ariel Canena & Arnaud Desbiez
We report 22 records of giant armadillo roadkill on Brazilian highways in the Cerrado, Pantanal and Amazon biomes illustrating that highways are a threat to this species. However, we also documented the species using underpasses, demonstrating that these structures could help to reduce the risk of roadkill for giant armadillos.

Data from: The effect of habitat fragmentation on the genetic structure of a top predator: loss of diversity and high differentiation among remnant populations of Atlantic Forest jaguars (Panthera onca)

Taiana Haag, Anelisie Santos, Denis Sana, Ronaldo Morato, , , Carlos De Angelo, Mario Di Bitetti, Francisco Salzano & Eduardo Eizirik
Habitat fragmentation may disrupt original patterns of gene flow and lead to drift-induced differentiation among local population units. Top predators such as the jaguar may be particularly susceptible to this effect, given their low population densities, leading to small effective sizes in local fragments. On the other hand, the jaguar's high dispersal capabilities and relatively long generation time might counteract this process, slowing the effect of drift on local populations over the time frame of...

Large wild herbivores slow down the rapid decline of plant diversity in a tropical forest biodiversity hotspot

Nacho Villar & Emilia Patricia Medici
1. The UN declaration of the Decade of Ecosystem Restoration 2021-2030 emphasizes the need for effective measures to restore ecosystems and safeguard biodiversity. Large herbivores regulate many ecosystem processes and functions, yet their potential as a nature-based solution to buffer against long-term temporal declines in biodiversity associated to global change and restore diversity in secondary forests remains unknown. 2. By means of an exclusion experiment, we tested experimentally the buffering effects of large wild herbivores...

Data from: Time-lag in responses of birds to Atlantic Forest fragmentation: restoration opportunity and urgency

Alexandre Uezu & Jean Paul Metzger
There are few opportunities to evaluate the relative importance of landscape structure and dynamics upon biodiversity, especially in highly fragmented tropical landscapes. Conservation strategies and species risk evaluations often rely exclusively on current aspects of landscape structure, although such limited assumptions are known to be misleading when time-lag responses occur. By relating bird functional-group richness to forest patch size and isolation in ten-year intervals (1956, 1965, 1978, 1984, 1993 and 2003), we revealed that birds...

Data from: The impacts of oil palm on recent deforestation and biodiversity loss

Varsha Vijay, Stuart L. Pimm, Clinton N. Jenkins & Sharon J. Smith
Palm oil is the most widely traded vegetable oil globally, with demand projected to increase substantially in the future. Almost all oil palm grows in areas that were once tropical moist forests, some of them quite recently. The conversion to date, and future expansion, threatens biodiversity and increases greenhouse gas emissions. Today, consumer pressure is pushing companies toward deforestation-free sources of palm oil. To guide interventions aimed at reducing tropical deforestation due to oil palm,...

Data from: Jaguar Movement Database: a GPS-based movement dataset of an apex predator in the Neotropics

Ronaldo G. Morato, Jeffrey J. Thompson, Agustín Paviolo, J. Antonio De La Torre, Fernando Lima, , Rogério C. Paula, , Leandro Silveira, Daniel L.Z. Kantek, Emiliano E. Ramalho, Louise Maranhão, Mario Haberfeld, Denis A. Sana, Rodrigo A. Medellin, Eduardo Carrillo, Victor Montalvo, Octavio Monroy-Vilchis, Paula Cruz, Anah Tereza Jácomo, Natalia M. Torres, Giselle B. Alves, Ivonne Cassaigne, Ron Thompson, Carolina Saenz-Bolanos … & Joares A. May
The field of movement ecology has rapidly grown during the last decade, with important advancements in tracking devices and analytical tools that have provided unprecedented insights into where, when, and why species move across a landscape. Although there has been an increasing emphasis on making animal movement data publicly available, there has also been a conspicuous dearth in the availability of such data on large carnivores. Globally, large predators are of conservation concern. However, due...

Data from: A comprehensive analysis of autocorrelation and bias in home range estimation

Michael J. Noonan, Marlee A. Tucker, Christen H. Fleming, Tom S. Akre, Susan C. Alberts, Abdullahi H. Ali, Jeanne Altmann, Pamela C. Antunes, Jerrold L. Belant, Dean Beyer, Niels Blaum, Katrin Böhning-Gaese, , Rogerio De Paula Cunha, Jasja Dekker, Jonathan Drescher-Lehman, Nina Farwig, Claudia Fichtel, Christina Fischer, Adam T. Ford, Jacob R. Goheen, René Janssen, Florian Jeltsch, Matthew Kauffman, Peter M. Kappeler … & Justin M. Calabrese
Home range estimation is routine practice in ecological research. While advances in animal tracking technology have increased our capacity to collect data to support home range analysis, these same advances have also resulted in increasingly autocorrelated data. Consequently, the question of which home range estimator to use on modern, highly autocorrelated tracking data remains open. This question is particularly relevant given that most estimators assume independently sampled data. Here, we provide a comprehensive evaluation of...
