Camera trapping and telemetry for detecting and quantifying animal interactions: Not anything goes

Ecological Indicators
Telemetry using Global Positioning Systems (GPS) and camera trapping are two widely used approaches to detect animal interactions involving wildlife. However, while the former follows an individual-based approach, the latter follows a population-based ...

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Snow Depth Estimation on Slopes Using GPS-Interferometric Reflectometry

Sensors, 2019
Snow is one of the most critical sources of freshwater, which influences the global water cycle and climate change. However, it is difficult to monitor global snow variations with high spatial−temporal resolution using traditional techniques due to

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Using GPS Technology to Understand Spatial and Temporal Activity of Kangaroos in a Peri-Urban Environment

Animals, 2018
The increasing kangaroo occurrence in expanding peri-urban areas can be problematic when kangaroos become aggressive towards people and present a collision risk to motor vehicles.

Shuttle/GPSPAC experimentation study [PDF]

The utilization is discussed of the GPSPAC, which is presently being developed to be used on the low altitude host vehicle (LAHV), for possible use in the shuttle avionics system to evaluate shuttle/GPS navigation performance.

Geographic Centroid Routing for Vehicular Networks [PDF]

, 2018
A number of geolocation-based Delay Tolerant Networking (DTN) routing protocols have been shown to perform well in selected simulation and mobility scenarios.

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

Methods in Ecology and Evolution, EarlyView.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

Beyond the next step: A multi‐criteria generative validation framework for step selection functions

Methods in Ecology and Evolution, EarlyView.
Abstract Step‐selection functions (SSFs), typically fitted using step‐selection analysis (SSA) or integrated step‐selection analysis (iSSA) are widely used to infer habitat selection and movement kernels from high‐frequency telemetry data, but most standard validation tools focus on one‐step‐ahead prediction and do not guarantee that fitted models ...
