Dear all,

We are glad to announce the following publication on Journal of the Marine
Biological Association of the United Kingdom

Occurrence, distribution and behaviour of Bryde's whales (Cetacea:
Mysticeti) off south-east BrazilLeandra Regina Gonçalves,

Abstract

Bryde's whales are among the lesser known balaenopterids found in Brazilian
waters, as well as globally. At the beginning of this project, only
occasional sightings of this species were identified off the coast of São
Paulo State. In this paper, we present the results of our investigations
into the occurrence and behaviour of Bryde's whales along the São Paulo
coast, both inside and outside the Marine State Park of Laje de Santos, as
a contribution to biological and behavioural knowledge of Bryde's whales
under the conservation scope. Sighting surveys were conducted from January
2003 to July 2005 in coastal and oceanic areas. During the survey, 42
sightings were made, totalling 71 individuals, between the isobaths of 20
and 3000 m. Sightings and individual rates were higher in coastal areas
during the summer season. Different kinds of behaviour were observed in
coastal and oceanic areas. At the 1200 m isobath, notable social
interactions were observed in which four adult individuals performed
breaching – the first report of this behavioural pattern for Brazil.
Results suggest that Bryde's whales possibly use coastal areas for feeding
and may migrate to oceanic areas for breeding, thus providing important
aspects that must be considered for the proper management of Marine
Protected Areas and for oceanic areas, especially considering the intensive
and continuous increase of oil and gas exploitation activities in those
areas. Data reported here, therefore, constitute a significant contribution
in Bryde's whale research and to cetacean conservation efforts in Brazil.
