Zoology Conference 2017 (2016)
The increased number of juvenile and newborn harbour porpoise strandings along the German Baltic coasts in summer provides evidence for a possible local calving and nursing ground in this area.…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Characterization, optimization, and validation of environmental DNA (eDNA) markers to detect an endangered aquatic mammal
Ma, Hongjuan; Stewart, Kathryn; Lougheed, Stephen; Zheng, Jinsong; Wang, Yuxiang; Zhao, Jianfu
Conservation Genetics Resources (2016)
Environmental DNA (eDNA) represents a sensitive and efficient method for noninvasively sampling rare or otherwise hard to monitor taxa, potentially making it a powerful tool for conservation management. Still, this…
Dual extinction: The illegal trade in the endangered totoaba and its impact on the critically endangered vaquita
Environmental Investigation Agency
Briefing to the 66th Standing Committee of CITES (2016)
The vaquita and the totoaba have much in common: both are critically endangered, both are protected from international trade under CITES and both are endemic to a relatively small area…
Echolocation detections and digital video surveys provide reliable estimates of the relative density of harbour porpoises
Williamson, Laura D.; Brookes, Kate L.; Scott, Beth E.; Graham, Isla M.; Bradbury, Gareth; Hammond, Philip S.; Thompson, Paul M.
Methods in Ecology and Evolution (2016)
1. Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into…
