The cruises took place in winter and spring of 1998-2001 with the objectives of investigating current distribution and abundance of cetaceans, particularly large whale species taken during whaling. In 1998 the survey were conducted between the parallels 5°30'W and 9°S and the 200 m isobath and the meridian 033°W. A total of about 3,100 nm were surveyed between 1998 and 2001 Surveys were conducted using line transect methods from about 5-10°S, and from the coast to 33°W. A total of 151 sightings (203 individuals) of large whales were recorded on effort. The Antarctic minke whale - Balaenoptera bonaerensis (Burmeister, 1867) was the most frequently sighted species (97 groups/132 individuals; Sighting Rate [SR] = 0.031 groups/nm), being recorded only in offshore waters. Density gradually increased from August to October. Minke whales were distributed throughout the area, both to the north and the south of former whaling ground. Sighting data indicate this is the most abundant species, particularly in the area beyond the continental shelf break. Breeding behavior was observed for Antarctic minke whales, but few groups containing calves were recorded (4.3% of the groups sighted on effort). Three other large whale species were recorded in low numbers: the Bryde's whale - Balaenoptera edeni (Anderson, 1879)1; the sei whale, B. borealis (Lesson, 1828), and the sperm, Physeter macrocephalus (Linnaeus, 1758). Sei, Bryde and sperm whales were regularly caught during whaling operations, but are rare in the area, suggesting they were depleted by whaling and have yet to recover to their pre-explotation abundance. In contrast, minke whales are abundant in this area, suggesting that either they were not substantially depleted, or that they have recovered rapidly. Blue whale, Balaenoptera musculus (Linnaeus, 1758), and fin whale, B. physalus (Linnaeus, 1758), not recorded on our surveys, have always been extremely rare in the area.eng--BrasilZoologia (Curitiba)-Bryde's whaleMinke whaleSei whaleSperm whaleSouth AtlanticDistribution and relative abundance of large whales in a former whaling ground off eastern South Americainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleAndriolo, ArturRocha, Jesuina M. daZerbini, Alexandre N.Simões-Lopes, Paulo C.Moreno, Ignacio B.Lucena, AlineideDanilewicz, DanielBassoi, Manuelainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILDistribution and relative abundance of large.pdf.jpgDistribution and relative abundance of large.pdf.jpgGenerated Thumbnailimage/jpeg1609https://repositorio.ufjf.br/jspui/bitstream/ufjf/8485/4/Distribution%20and%20relative%20abundance%20of%20large.pdf.jpg1d43c2078f8c0762759ad39f64f067fbMD54ORIGINALDistribution and relative abundance of large.pdfDistribution and relative abundance of large.pdfapplication/pdf965505https://repositorio.ufjf.br/jspui/bitstream/ufjf/8485/1/Distribution%20and%20relative%20abundance%20of%20large.pdff8e60711db64566189d7e9815bf4dc4dMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-82197https://repositorio.ufjf.br/jspui/bitstream/ufjf/8485/2/license.txt000e18a5aee6ca21bb5811ddf55fc37bMD52TEXTDistribution and relative abundance of large.pdf.txtDistribution and relative abundance of large.pdf.txtExtracted texttext/plain41094https://repositorio.ufjf.br/jspui/bitstream/ufjf/8485/3/Distribution%20and%20relative%20abundance%20of%20large.pdf.txtb207ee3b653c471f75e2dd68a3930aeeMD53ufjf/84852019-06-16 09:23:41.782oai:hermes.cpd.ufjf.br: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Repositório InstitucionalPUBhttps://repositorio.ufjf.br/oai/requestopendoar:2019-06-16T12:23:41Repositório Institucional da UFJF - Universidade Federal de Juiz de Fora (UFJF)false |
