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 ...

Using wingbeat frequency to estimate mass gain

Methods in Ecology and Evolution, EarlyView.
Abstract Energy intake is a fundamental currency in ecology that is critical to reproductive success, survival and lifetime fitness. Measuring foraging success in wild animals via biologgers has been a long‐standing challenge but is essential to understanding the mechanisms underlying population dynamics and species distributions.

Enriching historical biologging datasets on seabirds using deep neural networks: A transformer‐based approach to infer energy expenditure proxy from GPS and environmental data

Methods in Ecology and Evolution, EarlyView.
Abstract Recent advances in biologging have led to the widespread use of accelerometers, which generate high‐resolution movement data essential for understanding animal behaviour. Derived from tri‐axial accelerometry, Overall Dynamic Body Acceleration (ODBA) serves as a proxy for energy expenditure that is less invasive and more cost‐effective than ...

Behavioural responses to radio‐tag attachment in butterflies: Evidence for active tag removal

Ecological Entomology, EarlyView.
During controlled indoor flight experiments with 89 butterflies from eight tropical species, we monitored behavioural responses to dorsally attached radio tags using high‐speed video recordings. Four of 39 Morpho helenor exhibited coordinated abdominal flexion and hind leg movements directed toward the tag antenna during flight; in two individuals this

Open Biologging Data

Biologgers are animal-borne devices that remotely observe the individual’s location, behavior, physiology, and immediate environment. Over the last sixty years, biologging has become an invaluable tool for ecology, conservation, environmental science ...

Acclimatization length and post‐release spatial cohesion in translocated Griffon Vultures (Gyps fulvus)

Ibis, EarlyView.
Translocations are often used in the conservation of large raptors, including Old World vultures. Different release methods are usually assessed by comparing the movement patterns and survival of released individuals. However, these approaches fail to capture the gregarious behaviour of many vulture species.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...
