Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Deep learning‐based ecological analysis of camera trap images is impacted by training data quality and quantity

Remote Sensing in Ecology and Conservation, EarlyView.
Machine learning image classifiers are increasingly being used to automate camera trap image labelling, but we don't know how much ML model accuracy matters for downstream ecological analyses. Using two large data sets from an African savannah and an Asian dry forest ecosystem, we compared human labelled data with predictions from deep‐learning models ...

Doe Dose

, 2014
A plastic fawn, palm-sized, lives on my office desk. He gazes at my open office door. His right front hoof is raised, poised for haste. The deer of my Mississippi childhood were the Virginia whitetail, Odocoileus virginianus virginianus.

Knee height is often right: evaluating device height effects on camera trapping rate

Remote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...

An autonomous network of acoustic detectors to map tiger risk by eavesdropping on prey alarm calls

Remote Sensing in Ecology and Conservation, EarlyView.
Tiger population recovery brings with it increased fatalities from human‐tiger conflict. We describe a network of autonomous intelligent passive acoustic sensors that monitor the forest for deer alarm calls as a proxy for tiger risk and provide a risk map to local communities in real‐time.

Monitoring feral pigs (Sus scrofa): Complementarity between autonomous sensing methods increases detection probability

Remote Sensing in Ecology and Conservation, EarlyView.
Invasive alien species are a major threat for biodiversity worldwide and effective monitoring is paramount to inform management. In this study we used a multi‐season occupancy model to assess probability of detection between camera traps and passive acoustic recorders for feral pigs (Sus scrofa) during 1 year of data collection.

The Interactional Pathways of Mass Killings: Toward a Novel Understanding of Rampage School Shootings

Symbolic Interaction, EarlyView.
Rampage school shootings, where students go to their own school to randomly kill classmates, teachers, friends, and strangers, are among the most drastic types of human behavior. While research increasingly points to interaction dynamics as being key for the emergence of crime and violence, scholars have not yet systematically studied interaction ...

Estimating the seroprevalence of Mycobacterium bovis infection in a wild deer population in southwest England

Veterinary Record, EarlyView.
Abstract Background In England, transmission of Mycobacterium bovis between cattle and certain species of free‐roaming, wild deer has been implicated in some endemic bovine tuberculosis (bTB) regions. However, there are still data and knowledge gaps regarding the role of deer in the epidemiology of this disease.
