From shadows to data: first robust population assessment of snow leopards in Pakistan

Ecography, EarlyView.
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).

Wild bongo density estimation and population viability analysis improves conservation management

Global Ecology and Conservation, 2021
Bongo (Tragelaphus eurycerus eurycerus) are rare, mostly nocturnal forest antelopes in tropical Africa that are prized by trophy hunters for their large size, curved horns, and colorful pelage.

Profit With Purpose: How CSR Fuels UK SMEs' Success

Strategic Change, EarlyView.
ABSTRACT Corporate social responsibility (CSR) has become an essential strategy for firms, particularly small and medium‐sized enterprises (SMEs), to enhance their social impact and secure long‐term financial sustainability. This study explores the relationship between CSR investments and financial performance in UK listed SMEs from 2021 to 2024 ...

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

Wildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

Wildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

The analysis of cracking risk by shrinkage restraint of an alkali-activated slag mortar [PDF]

MATEC Web of Conferences, 2020
Alkali-activated slag (AAS) binders show in general larger autogeneous shrinkage strains than ordinary Portland cement (OPC) based binders. However, AAS can be a relevant alternative to OPC, if, for example low hydration heat release and fine pores, are ...

Integrating fecal DNA and telemetry to estimate wildlife densities in anthropogenic landscapes

Wildlife Society Bulletin, EarlyView.
Density estimation is central to wildlife management efforts but can be challenging in anthropogenic landscapes due to small parcel sizes, access restrictions, and limited green space. We evaluated (a) the use of a plot‐based spatial capture‐recapture sampling design to estimate deer density in developed landscapes and (b) if integrating telemetry data

Densities and perceptions of jaguars in coastal Nayarit, Mexico

Wildlife Society Bulletin, 2016
Conservation of large carnivores will require greater analyses of population parameters, habitat use, and distribution in multiuse landscapes as human populations increase and agriculture expands.

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 ...

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 ...
