Dear colleagues,

On behalf of my coauthors, I am pleased to announce the publication of our
article:

Zhitao Wang, Paul E. Nachtigall, Tomonari Akamatsu, Kexiong Wang, Yuping Wu,
Jianchang Liu, Guoqin Duan, Hanjiang Cao, Ding Wang, Passive acoustic
monitoring the diel, lunar, seasonal and tidal patterns in the biosonar
activity of the Indo-Pacific humpback dolphins (Sousa chinensis) in the
Pearl River Estuary, China, PLOS ONE, 2015, 10(11): e0141807, doi:
10.1371/journal.pone.0141807

   Abstract:

A growing demand for sustainable energy has led to an increase in
construction of offshore windfarms. Guishan windmill farm will be
constructed in the Pearl River Estuary, China, which sustains the world’s
largest known population of Indo-Pacific humpback dolphins (*Sousa
chinensis*). Dolphin conservation is an urgent issue in this region. By
using passive acoustic monitoring, a baseline distribution of data on this
species in the Pearl River Estuary during pre-construction period had been
collected. Dolphin biosonar detection and its diel, lunar, seasonal and
tidal patterns were examined using a Generalized Linear Model. Significant
higher echolocation detections at night than during the day, in
winter-spring than in summer-autumn, at high tide than at flood tide were
recognized. Significant higher echolocation detections during the new moon
were recognized at night time. The diel, lunar and seasonal patterns for
the echolocation encounter duration also significantly varied. These
patterns could be due to the spatial-temporal variability of dolphin prey
and illumination conditions. The baseline information will be useful for
driving further effective action on the conservation of this species and in
facilitating later assessments of the effects of the offshore windfarm on
the dolphins by comparing the baseline to post construction and post
mitigation efforts.
