Data from: A risk-based forecast of extreme mortality events in small cetaceans: using stranding data to inform conservation practice

Colin Bouchard, Cameron Bracken, Willy Dabin, Olivier Van Canneyt, Vincent Ridoux, Jérôme Spitz & Matthieu Authier
Effective conservation requires monitoring and pro-active risk assessments. We studied the effects of at-sea mortality events (ASMEs) in marine mammals over two decades (1990-2012) and built a risk- based indicator for the European Union’s Marine Strategy Framework Directive (MSFD). Strandings of harbour porpoises (Phocoena phocoena), short-beaked common dolphins (Delphinus delphis), and striped dolphins (Stenella coeruleoalba) along French coastlines were analysed using Extreme Value Theory (EVT). EVT operationalises what is an extreme ASME, and allows the...

High mortality rates in a juvenile free-ranging marine predator and links to dive and forage ability

Sam L Cox, Matthieu Authier, Florian Orgeret, Henri Weimerskirch & Christophe Guinet
1. High juvenile mortality rates are typical of many long-lived marine vertebrate predators. Insufficient development in dive and forage ability are considered key drivers of this. However, direct links to survival outcome are sparse, particularly in free-ranging marine animals that may not return to land. 2. In this study, we conduct exploratory investigations toward early mortality in juvenile southern elephant seals Mirounga leonina. 20 post-weaning pups were equipped with (1) a new generation satellite relay...
