Addressing important questions in animal ecology, physiology, and environmental science
often requires in situ information from wild animals. This difficulty is being overcome by …

Reliable estimation of the size or density of wild animal populations is very important for
effective wildlife management, conservation and ecology. Currently, the most widely used …

This is the fourth book dedicated to distance sampling. The first (Buckland et al. 1993)
appeared at around the same time as the first version of the Distance software (Laake et al …

The ancestors of marine mammals once roamed the land and independently committed to
an aquatic lifestyle. These macroevolutionary transitions have intrigued scientists for …

Cuvier's beaked whales (Ziphius cavirostris) are known as extreme divers, though
behavioral data from this difficult-to-study species have been limited. They are also the …

Ocean noise pollution is of special concern for cetaceans, as they are highly dependent on
sound as their principal sense. Sound travels very efficiently underwater, so the potential …

Beaked whales have mass stranded during some naval sonar exercises, but the cause is
unknown. They are difficult to sight but can reliably be detected by listening for echolocation …

Most marine mammal strandings coincident with naval sonar exercises have involved
Cuvier's beaked whales (Ziphius cavirostris). We recorded animal movement and acoustic …

Cetaceans are remarkable among mammals for their numerous adaptations to an entirely
aquatic existence, yet many aspects of their phylogeny remain unresolved. Here we merged …

Methods are developed for estimating the size/density of cetacean populations using data
from a set of fixed passive acoustic sensors. The methods convert the number of detected …
