Harbour Porpoises Are Flexible Predators Displaying Context‐Dependent Foraging Behaviours Open
Opportunistic mobile predators can adapt their behaviour to specific foraging scenarios, allowing them to target diverse prey resources. An interesting example is the harbour porpoise ( Phocoena phocoena ), a marine mammal with a huge ener…
Communities of metazoan parasites in seven sympatric skate species (Elasmobranchii, Rajidae) from the English Channel and Celtic Sea differing in conservation status Open
Elasmobranch populations are in steep decline mainly due to overfishing bycatch, but parasites may accelerate the collapse of vulnerable and/or highly parasitized species. We therefore studied metazoan parasites of Rajidae from the northea…
Harbour porpoises respond to recreational boats by speeding up and moving away from the boat path Open
Recreational boats are common in many coastal waters, yet their effects on cetaceans and other sensitive marine species remain poorly understood. To address this knowledge gap, we used drone video footage recorded from a recreational boat …
Harbour porpoises respond to small boats by speeding up and moving away Open
Recreational boats are common in many coastal waters, yet their effects on cetaceans and other sensitive marine species remain poorly understood. To address this knowledge gap, we used drone videos to quantify how harbour porpoises (Phocoe…
Sexual Behavior and Anatomy in Porpoises Open
Among the taxonomic family of porpoises (Phocoenidae), mating behavior in nature has been described in detail only for the harbor porpoise ( Phocoena phocoena ). We review this species’ unusual mating habits based on a study in San Francis…
Metazoan parasite community as a potential biological indicator in juveniles of the starry smooth-hound<i>Mustelus asterias</i>Cloquet, 1819 (<i>Carcharhiniformes Triakidae</i>) Open
The starry smooth-hound Mustelus asterias is a near-threatened coastal shark in Europe, whose parasitofauna is largely unknown. We studied metazoan parasites of 20 immature sharks (13 males and seven females) from the English Channel and w…
Using Drones to Measure Jellyfish Density in Shallow Estuaries Open
Understanding jellyfish ecology and roles in coastal ecosystems is challenging due to their patchy distribution. While standard net sampling or manned aircraft surveys are inefficient, Unmanned Aerial Vehicles (UAVs) or drones represent a …
