The Raffles Bulletin of Zoology (2002)
We studied the distribution and abundance of finless porpoises (Neophocaena phocaenoides) in Hong Kong and adjacent waters of China's Guangdong Province between September 1995 and November 2000. Vessel (50,194 km)…
The Raffles Bulletin of Zoology (2002)
Acoustic signals from free-ranging finless porpoises were recorded in the waters around Hong Kong during March 2000. Finless porpoises produced short-duration high-frequency clicks. Signal analysis showed finless porpoise clicks to…

EXTINCTION IS IMMINENT CIRVA reviewed the 2015 population survey results, which showed that only about 60 vaquitas remained at the beginning of the emergency 2-year partial gillnet ban. CIRVA also…
Marine Ecology Progress Series (2016)
A temporal and geographical analysis of echolocation activity can give insights into the behaviour of free-ranging harbour porpoises Phocoena phocoena. Seasonal and diel patterns in the presence and foraging activity…
Marine Ecology Progress Series (2004)
The echolocation behavior of harbor porpoises Phocoena phocoena around gillnets was monitored to test their response to chemically (BaSO4) enhanced gill nets, designed to be more acoustically reflective than commercial…
Marine Ecology Progress Series (2016)
Tidal-stream habitats present periodically fast-flowing, turbulent conditions. Evidence suggests that these conditions benefit top predators such as harbour porpoises Phocoena phocoena, presumably allowing them to optimise exploitation of prey resources.…
Environmental Research Letters (2011)
The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has…

Animals exposed to anthropogenic disturbance make trade-offs between perceived risk and the cost of leaving disturbed areas. Impact assessments tend to focus on overt behavioural responses leading to displacement, but…
Marine Ecology Progress Series (2013)
The west coast of Scotland is comprised of complex coastlines and topography, and a range of physical processes influence its coastal marine environment. The region is host to one of…
Aquatic Conservation: Marine and Freshwater Ecosystems (2010)
1. Assessments of anthropogenic impacts on cetaceans are often constrained by limited data on the extent to which these species use particular areas. 2. Timing porpoise detectors (T-PODs) are autonomous…
