Jaguar Density at the Northeastern Limit of Its Distribution in Mexico
Ecology and Evolution, Volume 16, Issue 2, February 2026.This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

Seasonal Drivers of Density in a Subarctic Population of Northern Red‐Backed Voles
Ecology and Evolution, Volume 16, Issue 2, February 2026.In this study, we analyzed 30 years of northern red‐backed vole population data from Denali National Park to examine how environmental factors influenced density over time. We found that this population showed cyclic population fluctuations with a 2–4 year period, with some variation between sampling sites, and that densities were positively associated

PLoS ONE, 2016 Many ecological theories and species conservation programmes rely on accurate estimates of population density. Accurate density estimation, especially for species facing rapid declines, requires the application of rigorous field and analytical methods ...

From shadows to data: first robust population assessment of snow leopards in Pakistan
Ecography, Volume 2026, Issue 2, February 2026.The snow leopard Panthera uncia is a flagship species of the greater Himalayan region and symbolizes the integrity of this ecological system. Within the greater Himalayas, Pakistan holds special significance as the north of the country represents a confluence of three major mountain ranges (Hindu Kush, Pamir–Karakoram, and Himalaya).

Balancing benefits and burdens: Tourist camps and lion conservation in the Maasai Mara
Conservation Science and Practice, Volume 8, Issue 2, February 2026.Wildlife tourism supports conservation and economies, but its rapid expansion can negatively impact ecosystems. Using spatially explicit lion density data from the Maasai Mara (2014–2022), we found that higher densities of tourist camps significantly reduce lion presence, independent of prey or vegetation, and that newly established camps displace ...

Estimating abundance of a cryptic social carnivore using spatially explicit capture–recapture
Wildlife Society Bulletin, 2019 Estimating population abundance of wolves (Canis lupus) in densely forested landscapes is challenging because reduced visibility lowers the success of methods such as aerial surveys and enumeration of group size using radiotelemetry.

Avocetta, 2016 Research on species-habitat relationship implies that a specific parameter related to the species, such as abundance, has to be measured and compared to environmental features.
