Evaluating camera survey methods for estimating wild turkey abundance

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
We relocated 92 eastern wild turkeys (Meleagris gallopavo silvestris) to an area unoccupied by conspecifics to evaluate efficacy of abundance estimation using camera‐trap techniques. We applied 8 common analytical methods (Schnabel, Huggins closed capture [Huggins], Huggins with random effects [HugginsRE], Jolly‐Seber, spatially explicit capture ...

Counting spots: Leopard density along a gradient of conservation rigor

open access: yesConservation Science and Practice, Volume 7, Issue 12, December 2025.
We assess the density of leopard populations in and around Kruger National Park in South Africa and investigate the drivers behind differences in leopard densities across the landscape. In well protected areas leopard population density is influenced by biological, bottom‐up processes with NDVI serving as a proxy for prey catchability.

Bridging the SME reporting gap: A new model for predicting Scope 1 and 2 emissions

open access: yesJournal of Industrial Ecology, Volume 29, Issue 6, Page 2197-2213, December 2025.
Abstract We present a novel statistical model for predicting Scope 1 and 2 emissions for small and medium‐sized enterprises (SMEs). Trained on financial transaction data from over 100,000 UK SMEs, the model targets a business segment excluded from formal emissions reporting and often under‐engaged in sustainability efforts.

A spatially explicit approach for estimating space use and density of common genets

open access: yesAnimal Biodiversity and Conservation
Un método espacialmente explícito para estimar el uso del espacio y la densidad de la jineta común Muchas especies que se presentan en bajas densidades no se estiman con precisión utilizando métodos de captura y recaptura, puesto que tales técnicas ...

Estimating canid territories and pack compositions: Camera traps provide comparable metrics to an intense radio‐collaring programme on dingoes

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Determining animal population structure and spacing often requires invasive approaches (e.g. trapping). We show key metrics can be reliably estimated for dingoes with camera traps, allowing researchers and practicioners to accurately, cost‐effectively and ethically characterise populations.

Finding the ghosts: Snow leopard density and distribution in the multi‐use region of Jammu and Kashmir, India

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
We assess the population of snow leopards in the multi‐use region of Paddar in Jammu and Kashmir, India. Alongside we also investigate local land uses and estimate snow leopard distribution across Jammu and Kashmir. This study adds to the evidence that big cats, especially snow leopards, need landscape‐level conservation strategies, rather than solely ...

Estimating abundance of a cryptic social carnivore using spatially explicit capture–recapture

open access: yesWildlife 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.

Measuring bird abundance - A comparison of methodologies between capture/recapture and audio-visual surveys

open access: yesAvocetta, 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.
