Since the early 1990s, there has been an active program in Hong Kong to manage and
protect local populations of small cetaceans from the effects of massive development in the …

Social systems are the outcomes of natural and sexual selection on individuals' efforts to
maximize reproductive success. Ecological conditions, life history, demography traits and …

Efforts to study the social acoustic signaling behavior of delphinids have traditionally been
restricted to audio-range (< 20 kHz) analyses. To explore the occurrence of communication …

Whistles are narrowband, frequency-modulated sounds produced by many cetaceans.
Whistles are extensively studied in delphinids, where several factors have been proposed to …

A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic
repertoires including the absence of whistles and high frequency but weak (low peak‐to …

In large social groups acoustic communication signals are prone to signal masking by
conspecific sounds. Bottlenose dolphins (Tursiops truncatus) use highly distinctive signature …

The study of marine soundscapes is a growing field of research. Recording hardware is
becoming more accessible; there are a number of off-the-shelf autonomous recorders that …

Passive acoustic monitoring (PAM) is increasingly being adopted as a non-invasive method
for the assessment of ocean ecological dynamics. PAM is an important sampling approach …

Coastal cetaceans are increasingly being exposed to boats and noise as nature tourism
grows. Such activity has a wide range of detrimental effects on the surface behaviour of …

Geographical and temporal trends in echolocation clicking activity can lead to insights into
the foraging and migratory behaviors of pelagic dolphins. Using autonomous acoustic …
