Acoustic harassment devices (AHD) or ‘seal scarers’ are used extensively, not only to deter seals from fisheries, but also as mitigation tools to deter marine mammals from potentially harmful sound…
The sex life of harbor porpoises (Phocoena phocoena): Lateralized and aerial behavior
Keener, William; Webber, Marc A.; Szczepaniak, Isidore D.; Markowitz, Tim M.; Orbach, Dara N.
Aquatic Mammals (2018)
The Golden Gate Bridge in San Francisco Bay provides a non-invasive aerial platform where harbor porpoises (Phocoena phocoena) can be observed mating. We photographed 144 mating events over an eight-year…
High field metabolic rates of wild harbour porpoises
Rojano-Doñate, Laia; McDonald, Birgitte I.; Wisniewska, Danuta M.; Johnson, Mark; Teilmann, Jonas; Wahlberg, Magnus; Højer-Kristensen, Jakob; Madsen, Peter T.
The Journal of Experimental Biology (2018)
Reliable estimates of field metabolic rates (FMRs) in wild animals are essential for quantifying their ecological roles, as well as for evaluating fitness consequences of anthropogenic disturbances. Yet, standard methods…
Report of the Eleventh meeting of the Comité Internacional para la Recuperación de la Vaquita (CIRVA)
(2019)
The members of the International Committee for the Recovery of the Vaquita (CIRVA), a group that has advised the Government of Mexico on the conservation of this species since 1997,…
Decline towards extinction of Mexico’s vaquita porpoise (Phocoena sinus)
Jaramillo-Legorreta, Armando M.; Cardenas-Hinojosa, Gustavo; Nieto-Garcia, Edwyna; Rojas-Bracho, Lorenzo; Thomas, Len; Ver Hoef, Jay M.; Moore, Jeffrey; Taylor, Barbara; Barlow, Jay; Tregenza, Nicholas
Royal Society Open Science (2019)
The vaquita (Phocoena sinus) is a small porpoise endemic to Mexico. It is listed by IUCN as Critically Endangered because of unsustainable levels of bycatch in gillnets. The population has…
Determination of optimal acoustic passive reflectors to reduce bycatch of odontocetes in gillnets
Kratzer, Isabella M. F.; Schäfer, Ingo; Stoltenberg, Arne; Chladek, Jérôme C.; Kindt-Larsen, Lotte; Larsen, Finn; Stepputtis, Daniel
Frontiers in Marine Science (2020)
The need to minimize bycatch of toothed whales (odontocetes) in gillnets has long been recognized, because they are often top predators and thus essential to ecosystem resilience. It is likely…
