Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

Wildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

Wildlife Biology, EarlyView.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Can local communities in Zimbabwe be trusted with wildlife management?: Evidence from contingent valuation of elephants [PDF]

If local communities living adjacent to the elephant see it as a burden, then they cannot be trusted to be its stewards. To assess their valuation of it, a CVM study was conducted for one CAMPFIRE district in Zimbabwe.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

The Welfare and Educational Impacts of Encounter Experiences and Displays on Zoo‐Housed Red Panda (Ailurus fulgens)

Zoo Biology, EarlyView.
We investigated the extent and composition of red panda (Ailurus Fulgens spp.) encounters amongst 150 global zoos and their impact on animal longevity and reproduction. Comparative data analysis suggests that encounter animals produced more offspring and had higher longevity (survival) than non‐encounter animals with differences noted between ...

Behavior Change Projects in Zoological Collections: Application of the Behavior Change Wheel

Zoo Biology, EarlyView.
Projects identified from zoo websites and their initial categorization. ABSTRACT Human behavior change is needed to stop the triple planetary crisis. Zoos reach millions of people every year and there is evidence available that people do change their behavior because of zoo led interventions.
