Harbour porpoise signals consist of directional, high frequency stereotypic clicks which can be logged using T-PODs. Variation in interclick intervals (ICIs) can be used to distinguish different acoustic behaviours. So…
The harbour porpoise (Phocoena phocoena) is an important top predator and as such an indicator species for its environment. Before the beginning of the 21st century, little data existed on…
The T-POD (Timing POrpoise Detector) is a self-contained acoustic data logger used for detecting and monitoring the presence of echolocation clicks of small cetaceans. It has become a standard tool…
A yearling male harbor porpoise (Phocoena phocoena) stranded alive on the shores of Avon, North Carolina, and was rehabilitated for nearly 10 mo at the National Aquarium in Baltimore and…
Regular monitoring of the status of cetacean populations is essential for conservation, policy and management. By using a passenger ferry as a scientific research platform, this study provides information on…
(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
With the United Kingdom required to designate Special Areas of Conservation (SACs) under Natura 2000 by 2012, it is important to understand site-specific activity and habitat use in order to…
The 50% detection hearing thresholds of a harbor porpoise for a 4.0 kHz narrow-band FM signal, presented at the background noise level in a pool and with two masking noise…
Finfish aquaculture is a prominent industry in the Bay of Fundy, Canada. The distribution of harbour porpoise (Phocoena phocoena) in the Bay during the summer and fall may be impacted…
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
