Resumo: Behavior of humpback whales was observed during the reproductive period off the northern coast of the state of Bahia (NB, n = 378 groups) and at the Abrolhos Bank (AB, n = 919) to compare patterns and group composition between the two locations. Alone individuals and dyads were most often encountered in both areas, although mother-calf pairs were more common in AB. While these two regions comprise distinct concentrations of humpback whales, with intrinsic environmental differences, behavior patterns were quite similar. The only behavioral differences found where for "tail up" and "resting". The patterns found here may reflect differences in the protection status of the areas or intrinsic environmental differences.

Foram analisados 378 grupos de baleias jubarte no LNB e 919 no BA. Obteve-se uma predominância de duplas e animais solitários em ambas as áreas. No entanto, grupos de "fêmea e filhote" foram mais comumente observados no BA, quando comparados ao LNB. Apesar das duas áreas serem distintas quanto à concentração de baleias jubarte, com diferenças ambientais intrínsecas, obtiveram-se probabilidades de ocorrência das condutas bastante similares para ambas as áreas. Diferenças significativas na probabilidade de ocorrência foram obtidas apenas para as condutas "exposição da caudal" e "repouso". As diferenças obtidas neste estudo, comparando-se as duas regiões amostradas, possivelmente refletem diferenças no status de proteção da área e/ou características ambientais intrínsecas a cada área.Em processamentoSociedade Brasileira de Zoologia2017-12-07T04:49:31Z2017-12-07T04:49:31Z2008info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRev.
