Summary: | This study was carried out in forest fragments located in the Atlantic Rainforest, in the town of Anchieta, south of Espírito Santo State, Brazil (located at latitude 20o40'S to 20o48'S, longitude 40o34'W to 40o42'W), along the seasons of 2008. The main objective of the study was to analyze the groups of birds that were affected by the forest fragmentation and the degree of isolation of these areas. The method used to register the avifauna specimens was the technique of observation per fixed point. Thus, the Shannon-Weaver diversity index (H'=4.18) was calculated, showing a significant abundance in the studied areas, and Equitability (E=0.81), suggesting that the number of species registered at the site represented the maximum capacity the areas were able to shelter. The Index of Point Abundance (IPA) was also calculated for each species. The IPA varied from 0.0042 (one contact) to 0.9500 (228 contacts), with a large number of species with low IPA and a few species with intermediate or high IPA. Taking into account 80 hours of observations, it was possible to register a total of 168 species of birds, distributed over a range of 45 families, 20 orders, and grouped in eight trophic guilds. Omnivores and insectivores were the most abundant, with 58 and 52 species respectively. The species most affected by the forest fragmentation were the great frugivores and understorey insectivorous birds. |

Avifauna in forest fragments of the Atlantic Rainforest in the south of Espírito Santo state, BrazilAvifauna em fragmentos florestais da Mata Atlântica no sul do Espírito SantoThis study was carried out in forest fragments located in the Atlantic Rainforest, in the town of Anchieta, south of Espírito Santo State, Brazil (located at latitude 20o40'S to 20o48'S, longitude 40o34'W to 40o42'W), along the seasons of 2008.

O principal objetivo foi analisar os grupos de aves afetados pela fragmentação florestal e o isolamento destas áreas. O método utilizado para o registro da avifauna foi o de observações por pontos fixos e foram calculados o Índice de Diversidade de Shannon-Weaver (H'=4,18), indicando uma riqueza expressiva dos ambientes estudados; Índice de Equidade de Pielou (E=0,81) para as áreas estudadas, indicando que as espécies observadas nestes ambientes representam quase a capacidade máxima que estas áreas podem abrigar; e o Índice Pontual de Abundância para as espécies registradas, que variou entre 0,0042 (um contato) e 0,9500 (228 contatos), com grande número de espécies com baixo IPA e poucas espécies com IPA intermediário ou alto. Foi possível registrar, em 80 horas de observações, 168 espécies de aves, distribuídas em 45 famílias, 20 ordens e agrupadas em oito guildas tróficas, sendo onívoro e insetívoro as mais abundantes, respectivamente com 58 e 52 espécies. As espécies mais afetadas pela fragmentação florestal foram os grandes frugívoros e os insetívoros de sub-bosque.Universidade Federal de Santa Catarina2010-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2010v23n3p10510.5007/2175-7925.2010v23n3p105Biotemas; v. 23 n. 3 (2010); 105-1152175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2010v23n3p105/14438Copyright (c) 2010 Fabio Rossano Darioinfo:eu-repo/semantics/openAccessDario, Fabio Rossano2022-11-21T14:12:40Zoai:periodicos.ufsc.br:article/15950Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T14:12:40Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
