Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

open access: yesIbis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Linoleic Acid Enhances Murine Natural Killer Cell Function In Vitro but Compromises Mitochondrial Bioenergetic Function During Retroviral Infection

open access: yesImmunology, EarlyView.
Natural Killer (NK) cells are potent effectors against virus‐infected and tumour cells. During Friend Virus (FV) infection, fatty acid metabolism supports NK‐cell effector functions. Here, we found that NK cells from FV‐infected mice preferentially take up linoleic acid (LA), which reduced proliferation, mitochondrial function, and increased reactive ...

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

open access: yesJournal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Rosmarinus officinalis essential oil components promote anaesthesia in Colossoma macropomum (Cuvier, 1818) through behavioural and cardiorespiratory modulation

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anaesthetic management plays a crucial role in maintaining the welfare and physiological stability of fish during routine aquaculture and research procedures. The essential oil of Rosmarinus officinalis (ROEO) has emerged as a promising natural anaesthetic; however, its cardiophysiological effects in Amazonian species remain underexplored ...
