Dear Colleagues,

We'd like to draw your attention to our paper "Humpback whales washed
ashore in southeastern Brazil...", which was recently published in
Biologia<http://www.springer.com/life+sciences/journal/11756>
(Springer).
The abstract is below and the article can be found at:

*ABSTRACT*:
In the Southwest Atlantic Ocean the wintering breeding ground of *Megaptera
novaeangliae* is located in northeastern coast of Brazil, mainly in the
Abrolhos Bank (16°55′ S, 38°50′ W) and its surroundings. During migratory
percussion, events of strandings are thought to occur. A total of 58
stranded humpback whales were recorded between 1981 and 2011 along the
coast of the Rio de Janeiro state, Brazil. The number of strandings in 20
years (1992–2011) increased during the period of study, with a mean of 2.6
events per year. In 2010 a peak occurred with 13 records of strandings.
Most of them occurred preferably in the southern half of the study area, or
in the southeast area of Rio de Janeiro state. Three cases of entanglement
were found, two of these involving calves with less than eight meters of
body length. Stranding events were more frequent during winter and spring.
No statistical differences were found between age categories, but 33% were
classified as “dependent calf” (< 8 m length). Males stranded more often
than females. Only one whale out of 16 specimens that had the stomach
contents examined presented food remains, but comprising only two
cephalopod beaks of the squid *Doryteuthis sanpaulensis*. Bacteriological
survey of Vibrionaceae and Aeromonadaceae agents in three live stranded
whales on the Brazilian coast indicated evidence of animal impairment that
resulted or were associated with the cause of death and stranding event.

All the best,
