Using biotelemetry to assess drone effects on whale sharks

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The use of unoccupied aerial vehicles or drones for wildlife research has proliferated in recent years and they have proven to be a valuable tool for collecting data for population surveys, morphometric and body condition measurements, and for observing behavior.

Tracking interannual variation of a large‐scale ocean front influences foraging in a mesopelagic predator

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Macroscale ocean fronts aggregate significant biomass and provide critical foraging habitat for large marine predators. These frontal systems shift in response to ocean climate variation, including basin‐scale oscillations, and the degree to which marine predators track these movements affects their foraging and reproductive success. Using two

Indirect effects of fast‐growing urban development on wildlife in a coastal protected area of Costa Rica

The Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We studied the effects of urban growth on wildlife near Parque Nacional Marino las Baulas, Costa Rica. Since 1991, buildings increased 1007%, mainly in the buffer zone. We identified eight native species extracting garbage from containers, with raccoons (Procyon lotor) comprising most detections (84%), and four other species being potential sea turtle ...

Identifying the Extent of River‐Influenced Waters of the Transpolar Drift With In Situ Measurements of Dissolved Organic Matter Fluorescence and Seawater Density

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The oceanic component of the Transpolar Drift (TPD) is a key component of Arctic Ocean surface circulation. However, our understanding of its spatial extent and influence on the underlying water column remains limited. This study leverages a unique high spatial resolution oceanographic transect from August 2022 (late summer), first to identify

Larsen C Ice Shelf in the Western Weddell Sea is a Hotspot for Export Production in the Antarctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The Southern Ocean accounts for >30% of the global ocean CO2 sink as a result of its solubility and biological pumps. To investigate the biological pump near Larsen C Ice Shelf (LCIS) in the Southern Ocean's western Weddell Sea, we measured the concentrations and nitrogen isotope ratios of nitrate, ammonium, and particulate organic nitrogen ...

movetrack: An R package to model flight paths from radio‐telemetry networks

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1069-1081, April 2026.
Abstract Tracking small‐ to large‐scale movements of animals is important for studying their interactions with the environment, including how they adjust and adapt their migration in response to environmental and human‐induced changes. Despite the technical progress in tracking devices, a major challenge remains for small animals—such as songbirds ...
