The Effects of Noise on Aquatic Life II (2016)
In recent years, several sound and movement recording tags have been developed to sample the acoustic field experienced by cetaceans and their reactions to it. However, little is known about…
Isolation of culturable aerobic bacteria and evidence of Kerstersia gyiorum from the blowhole of captive Yangtze finless porpoises
Wan, Xiaoling; McLaughlin, Richard William; Zhou, Junying; Hao, Yujiang; Zheng, Jinsong; Wang, Ding
Antonie van Leeuwenhoek (2016)
Bacterial respiratory illnesses are problematic in aquatic mammals such as the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis; YFP), which is now at a critically endangered status. Yet little is known…
Comparing distribution of harbour porpoises (Phocoena phocoena) derived from satellite telemetry and passive acoustic monitoring
Mikkelsen, Lonnie; Rigét, Frank F.; Kyhn, Line A.; Sveegaard, Signe; Dietz, Rune; Tougaard, Jakob; Carlström, Julia A. K.; Carlén, Ida; Koblitz, Jens C.; Teilmann, Jonas
PLOS ONE (2016)
Cetacean monitoring is essential in determining the status of a population. Different monitoring methods should reflect the real trends in abundance and patterns in distribution, and results should therefore ideally…
Exploitation of coastal fish communities by harbour porpoises Phocoena phocoena during nursing periods in German Baltic waters
Pinzone, M.; Michel, L. N.; Gallus, A.; Brundiers, K.; Sturaro, N.; Andreasen, H.; Dähne, M.; Lepoint, G.; Siebert, U.; Das, K.; Benke, H.
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…
Estimates of cetacean by-catch in the turbot fishery on the Turkish Western Black Sea Coast in 2007 and 2008
Tonay, Arda M.
Journal of the Marine Biological Association of the United Kingdom (2016)
This is the first study estimating cetacean by-catch in the Turkish western Black Sea turbot fishery. One turbot fishing boat was observed during two fishing seasons, from April through July…
Extinction is imminent for Mexico’s endemic porpoise unless fishery bycatch is eliminated
Taylor, Barbara L.; Rojas-Bracho, Lorenzo; Moore, Jeffrey; Jaramillo-Legorreta, Armando; Ver Hoef, Jay M.; Cardenas-Hinojosa, Gustavo; Nieto-Garcia, Edwyna; Barlow, Jay; Gerrodette, Tim; Tregenza, Nicholas; Thomas, Len; Hammond, Philip S.
Conservation Letters (2016)
The number of Mexico's endemic porpoise, the vaquita (Phocoena sinus), is collapsing primarily due to bycatch in illegal gillnets set for totoaba (Totoaba macdonaldi), an endangered fish whose swim bladders…
