Evidence of tide pool use by a viviparous elasmobranch as a parturition site [PDF]
Acta Ichthyologica et Piscatoria, 2019 Despite the frequent occurrence of elasmobranchs in surf zones, the use of tidal pools by these animals is unknown, with only one incidental observation reported in the literature.

Geometric factors influencing the diet of vertebrate predators in marine and terrestrial environments [PDF]
, 2014 Predator–prey relationships are vital to ecosystem function and there is a need for greater predictive understanding of these interactions. We develop a geometric foraging model predicting minimum prey size scaling in marine and terrestrial vertebrate ...

A socio‐psychological approach for understanding and managing bycatch in small‐scale fisheries
People and Nature, 2023 Fisheries bycatch is the greatest threat to migratory, long‐lived marine animals. Addressing bycatch ultimately requires changing fisher behaviour, yet social and behavioural sciences are rarely applied to bycatch mitigation, with an absence of theory ...

Catch Composition, Seasonality, and Biological Aspects of Sharks Caught in the Ecuadorian Pacific
Diversity, 2022 Although sharks have a fundamental role in maintaining the balance of aquatic ecosystems, exerting a great influence on lower levels of the food chain, their populations are declining worldwide due, to a large extent, to overfishing.

Animals, 2022 Acute-stress situations in vertebrates induce a series of physiological responses to cope with the event. While common secondary stress responses include increased catabolism and osmoregulatory imbalances, specific processes depend on the taxa.

Twins! Microsatellite analysis of two embryos within one egg case in oviparous elasmobranchs.
PLoS ONE, 2019 Elasmobranchs display various reproductive modes, which have been key to their evolutionary success. In recent decades there has been a rise in the number of reported cases of foetal abnormalities including fertilised, double-embryos held within one egg ...
