A general swimming response in exhausted obligate swimming fish

Royal Society Open Science, 2022
Marine organisms normally swim at elevated speeds relative to cruising speeds only during strenuous activity, such as predation or escape. We measured swimming speeds of 29 ram ventilating sharks from 10 species and of three Atlantic bluefin tunas ...

Inferring the Number of Spawning Events From Young‐of‐the‐Year Genomic Samples and Otolith‐Derived Birth Dates: A Richness‐Estimator Perspective

Fish and Fisheries, EarlyView.
ABSTRACT Estimating the number of spawning events per female is key to understanding reproductive output in batch‐spawning species, yet direct observation is often infeasible in the wild. Recent advances in genetic kinship inference enable the identification of maternal half siblings from young‐of‐the‐year genomic samples, while otolith‐based age ...

Intra-seasonal variation in feeding rates and diel foraging behaviour in a seasonally fasting mammal, the humpback whale

Royal Society Open Science, 2022
Antarctic humpback whales forage in summer, coincident with the seasonal abundance of their primary prey, the Antarctic krill. During the feeding season, humpback whales accumulate energy stores sufficient to fuel their fasting period lasting over six ...

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.

Acoustic signalling and behaviour of Antarctic minke whales (Balaenoptera bonaerensis)

Royal Society Open Science, 2022
Acoustic signalling is the predominant form of communication among cetaceans. Understanding the behavioural state of calling individuals can provide insights into the specific function of sound production; in turn, this information can aid the evaluation

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 ...

Differing drivers of decline within a migratory metapopulation has implications for future conservation

Ecology and Evolution, 2023
Researchers generally ascribe demographic drivers in a single sub‐population and presume they are representative. With this information, practitioners implement blanket conservation measures across metapopulations to reverse declines.

Quantifying post‐release behaviour of a critically endangered elasmobranch over two capture events using high‐resolution archival tag data

Journal of Fish Biology, EarlyView.
Abstract During catch‐and‐release angling, highly resident species are susceptible to multiple recapture events. Biologging offers the opportunity to study post‐release behaviour in detail; however, most studies have focused on a single capture‐release event.

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.

Evaluating the behavioural consequences of external pop‐off biologging packages on two freshwater fishes

Journal of Fish Biology, EarlyView.
Abstract Quantifying the behaviour of animals in the wild can provide important information on their ecology and welfare. External biologgers that ‘pop‐off’ to enable tag retrieval have been widely used in marine systems; however, they have only recently been applied to freshwater fishes.
