Resumo: Reproduction and population dynamics of Didelphis aurita Wied-Neuwied (Mammalia: Didelphimorphia) in the periurban environment of Santa Catarina Island, in southern Brazil. The various aspects of reproduction and population dynamics of Didelphis aurita were studied through capture-recapture on Santa Catarina Island, in southern Brazil. Surveys were carried out from April 1996 to March 1997. The study area was located near the stream of a swamp in a disturbed Atlantic Forest area. On 880 trap-nights, 31 opossums were captured on 108 occasions during one year. The results of this paper indicate a seasonal polyestrous reproduction pattern. Autumn-winter population levels grew on account of juvenile recruitment. The sex ratio  favored females in first captures and total captures. Emigration was discussed as being the main reason for the female bias. The effects of sampling procedures over deviation in the pouch young sex ratio of resident  females were also discussed.

No total, 31 indivíduos foram capturados 108 vezes, com um esforço de coleta de 880 armadilhas-noite. Os resultados sugerem um padrão reprodutivo poliéstrico sazonal e um aumento populacional durante o outono/inverno atribuído à entrada de jovens na população. A proporção sexual foi desviada para as fêmeas em relação ao número de indivíduos capturados e capturas totais. A principal causas desses desvios pode ser devido à emigração de machos jovens. Os efeitos de procedimentos de amostragem sobre desvios na proporção sexual  de filhotes de fêmeas residentes também são discutidos.Universidade Federal de Santa Catarina2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21331Biotemas; v. 19 n. 1 (2006); 65-732175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21331/19240Copyright (c) 2006 Maurício Eduardo Graipel, Manoel dos Santos Filhohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGraipel, Maurício EduardoFilho, Manoel dos Santos2022-11-21T11:37:34Zoai:periodicos.ufsc.br:article/21331Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:37:34Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
