High-resolution biologging of an Atlantic bluefin tuna captured and eaten by a supposed orca. [PDF]

Sci Rep
Biologging has been used on a range of wild animals to document spectacular feats of migration and behaviour. We describe the pursuit, capture, and ingestion of an adult Atlantic bluefin tuna (Thunnus thynnus) (175 cm, estimated weight: 81 kg), which was

Field immobilisation of adult Weddell seals using intramuscular butorphanol and midazolam

Veterinary Record, EarlyView.
Abstract Background When working with free‐ranging phocid seals, methods of chemical immobilisation require ongoing refinement to reduce complications, particularly apnoea, during research procedures. Methods Adult Weddell seals (n = 20) at Cape Crozier, Antarctica, were chemically immobilised with intramuscular injection of butorphanol and midazolam ...

A framework for the ethical use of animal‐borne devices in post‐release monitoring following rehabilitation

Wildlife Biology, EarlyView.
Rehabilitation and release contribute to conservation efforts for threatened species. Ensuring that these efforts are effective requires a good understanding of the factors which determine survival and integration of released animals into wild populations.

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

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

Wildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

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.

Biologics in Dermatology [PDF]

Pharmaceuticals, 2013
Skin and subcutaneous diseases affect millions of people worldwide, causing significant morbidity. Biologics are becoming increasingly useful for the treatment of many skin diseases, particularly as alternatives for patients who have failed to tolerate or respond to conventional systemic therapies.

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

Streamlining biologging technology [PDF]

, 2018
The understanding of the interplay of movement, behaviour and physiology that biologging offers has applied relevance for a range of fields, including evolutionary ecology, wildlife conservation and behavioural ecology.
