Data from: Robust inference on large-scale species habitat use with interview data: the status of jaguars outside protected areas in Central America

Foster, Bart Harmsen, Sandra Hernández-Potosme, Luis Herrera, Melva Olmos, Sandy Pereira, Hugh S. Robinson, Nathaniel Robinson, Roberto Salom-Pérez, Yahaira Urbina, Kathy A. Zeller & Howard Quigley
Evaluating range-wide habitat use by a target species requires information on species occurrence over broad geographic regions, a process made difficult by species rarity, large spatiotemporal sampling domains, and imperfect detection. We address these challenges in an assessment of habitat use for jaguars (Panthera onca) outside protected areas in Central America. Occurrence records were acquired within 12 putative corridors using interviews with knowledgeable corridor residents. We developed a Bayesian hierarchical occupancy model to gain robust...

Data from: Flexibility in the duration of parental care: female leopards prioritise cub survival over reproductive output

Guy A. Balme, Hugh S. Robinson, Ross T. Pitman & Luke T. B. Hunter
1.Deciding when to terminate care of offspring is a key consideration for parents. Prolonging care may increase fitness of current offspring, but it can also reduce opportunities for future reproduction. Despite its evolutionary importance, few studies have explored the optimal duration of parental care, particularly among large carnivores. 2.We used a 40-year dataset to assess the trade-offs associated with the length of maternal care in leopards in the Sabi Sand Game Reserve, South Africa. We...

Data from: Leopard distribution and abundance is unaffected by interference competition with lions

Guy A. Balme, Ross T. Pitman, Hugh S. Robinson, Jennie R.B. Miller, Paul J. Funston & Luke T.B. Hunter
Competition can have profound impacts on the structure and function of ecological communities. Despite this, the population-level effects of intraguild competition on large carnivores remain largely unknown, due to a paucity of long-term studies that focus simultaneously on competing species. Here, we comprehensively examine competitive interactions, including their demographic consequences, between 2 top predators, lions Panthera leo and leopards P. pardus. We tested the hypothesis that lions, as the dominant competitor, limit the distribution and...

The snow leopard, Panthera uncia, is an elusive high-altitude specialist that inhabits vast, inaccessible habitat across Asia. We conducted the first range-wide genetic assessment of snow leopards based on noninvasive scat surveys. Thirty-three microsatellites were genotyped and a total of 683-bp of mitochondrial DNA sequenced in 70 individuals. Snow leopards exhibited low genetic diversity at microsatellites (AN = 5.8, HO = 0.433, HE = 0.568), virtually no mtDNA variation, and underwent a bottleneck in the...

Data from: Caching reduces kleptoparasitism in a solitary, large felid

Guy Balme, Jennifer R. B. Miller, Ross T. Pitman, Luke T. B. Hunter & Guy A. Balme
Food caching is a common strategy used by a diversity of animals, including carnivores, to store and/or secure food. Despite its prevalence, the drivers of caching behaviour, and its impacts on individuals, remain poorly understood, particularly for short-term food cachers. Leopards Panthera pardus exhibit a unique form of short-term food caching, regularly hoisting, storing and consuming prey in trees. We explored the factors motivating such behaviour among leopards in the Sabi Sand Game Reserve, South...

Data from: Effective implementation of age restrictions increases selectivity of sport hunting of the African lion

Colleen M. Begg, Jennifer R. B. Miller & Keith S. Begg
1. Sport hunting of wildlife can play a role in conservation but can also drive population declines if not managed sustainably. Previous simulation modelling found that large felid species could theoretically be hunted sustainably by restricting harvests to older individuals that have likely reproduced. Several African countries currently use age-based hunting for lions although the outcomes have yet to be evaluated in a wild population. 2. Here we provide the first empirical evidence that a...

Data from: Continental divide: predicting climate-mediated fragmentation and biodiversity loss in the boreal forest

Dennis L. Murray, Michael J.L. Peers, Yasmine N. Majchrzak, Morgan Wehtje, Catarina Ferreira, Rob S.A. Pickles, Jeffrey R. Row, Daniel H. Thornton, Michael J. L. Peers & Rob S. A. Pickles
Climate change threatens natural landscapes through shifting distribution and abundance of species and attendant change in the structure and function of ecosystems. However, it remains unclear how climate-mediated variation in species' environmental niche space may lead to large-scale fragmentation of species distributions, altered meta-population dynamics and gene flow, and disrupted ecosystem integrity. Such change may be especially relevant when species distributions are restricted either spatially or to a narrow environmental niche, or when environments are...
