Energyscapes and prey fields shape a North Atlantic seabird wintering hotspot under climate change [PDF]

Royal Society Open Science, 2018
There is an urgent need for a better understanding of animal migratory ecology under the influence of climate change. Most current analyses require long-term monitoring of populations on the move, and shorter-term approaches are needed. Here, we analysed

Direct measurement of swimming and diving kinematics of giant Atlantic bluefin tuna (Thunnus thynnus) [PDF]

Royal Society Open Science, 2019
Tunas possess a range of physiological and mechanical adaptations geared towards high-performance swimming that are of considerable interest to physiologists, ecologists and engineers.

Foraging Behaviours of Breeding Arctic Terns Sterna paradisaea and the Impact of Local Weather and Fisheries

Frontiers in Marine Science, 2022
During the breeding season, seabirds are central place foragers and in order to successfully rear chicks they must adjust their foraging behaviours to compensate for extrinsic factors.

Providing baseline data for conservation–Heart rate monitoring in captive scimitar-horned oryx

Frontiers in Physiology, 2023
Heart rate biologging has been successfully used to study wildlife responses to natural and human-caused stressors (e.g., hunting, landscape of fear). Although rarely deployed to inform conservation, heart rate biologging may be particularly valuable for

Western Gull Foraging Behavior as an Ecosystem State Indicator in Coastal California

Frontiers in Marine Science, 2022
With accelerating climate variability and change, novel approaches are needed to warn managers of changing ecosystem state and to identify appropriate management actions.

Increased Diurnal Activity Is Indicative of Energy Deficit in a Nocturnal Mammal, the Aardvark

Frontiers in Physiology, 2020
Shifting activity to cooler times of day buffers animals from increased heat and aridity under climate change. Conversely, when resources are limited, some nocturnal species become more diurnal, reducing energetic costs of keeping warm at night ...

Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator

Royal Society Open Science, 2022
The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination of both physiological and ...

Intrinsic and extrinsic factors drive ontogeny of early-life at-sea behaviour in a marine top predator [PDF]

, 2017
Young animals must learn to forage effectively to survive the transition from parental provisioning to independent feeding. Rapid development of successful foraging strategies is particularly important for capital breeders that do not receive parental ...

Asset Tracking Whales—First Deployment of a Custom-Made GPS/GSM Suction Cup Tag on Migrating Humpback Whales

Journal of Marine Science and Engineering, 2021
The study of marine mammals is greatly enhanced through fine scale data on habitat use. Here we used a commonly available asset tracker Global Positioning System/Global Systems for Mobile Communication (GPS/GSM) integrated into a CATS suction cup tag to ...
