Predictions from harbor porpoise habitat association models are confirmed by long-term passive acoustic monitoring
Brookes, Kate L.; Bailey, Helen; Thompson, Paul M.
The Journal of the Acoustical Society of America (2013)
Survey based habitat association models provide good spatial coverage, but only a snapshot in time of a species' occurrence in a particular area. A habitat association model for harbor porpoises…
The stranding anomaly as population indicator: The case of harbour porpoise Phocoena phocoena in north-western Europe
Peltier, Helene; Baagøe, Hans J.; Camphuysen, Kees C. J.; Czeck, Richard; Dabin, Willy; Daniel, Pierre; Deaville, Rob; Haelters, Jan; Jauniaux, Thierry; Jensen, Lasse F.; Jepson, Paul D.; Keijl, Guido O.; Siebert, Ursula; Van Canneyt, Olivier; Ridoux, Vincent
PLoS ONE (2013)
Ecological indicators for monitoring strategies are expected to combine three major characteristics: ecological significance, statistical credibility, and cost-effectiveness. Strategies based on stranding networks rank highly in cost-effectiveness, but their ecological…
