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 ...

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

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.

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
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.

A behavioral study of the nocturnal activity budget and rhythmicity reveals the relationship between lying cycle (LC) duration and time spent in the REM‐sleep posture (“lying – head down”, LHD) in zoo‐housed Lowland tapirs (Tapirus terrestris) and Malayan tapirs (Tapirus indicus). ABSTRACT To ensure and optimize husbandry conditions, zoo management and

The Spatial Econometrics of Elephant Population Change: A Note [PDF]
While previous research found no other variable than corruption to have a negative impact on (the growth rate of) the African countries' elephant populations, we show that one further significant impact is exerted by what one might call neighbourhood ...
