“…The increase of food supply does not seem to be so high in the Apertados river as in Alaska, but certainly ground invertebrates could be benefited with the humidity and could have their abundance increased. The bird guild that could benefit most from increased invertebrate abundance is the ground omnivores (VOLPATO et al 2006); that guild had almost the twice the number of contacts along the riparian trails (167) compared to the upland ones (90).…”

We compared the composition and guild structure of bird communities of riparian and upland forest in an Atlantic forest reserve, the Godoy State Park (GP), in northern Paraná State, southern Brazil. Unlimited distance point counts were sampled monthly from September-December 2001, along four trails. Two trails in upland forest (TA and TB) were parallel to each other and about 300 m apart. Two trails in riparian forest (TC and TD) were along the Apertados River, about 100 m away from the river. A total of 145 species were recorded: 81 species were recorded in both upland and riparian forests, 19 species were recorded only in upland forest and 45 species were recorded exclusively in riparian forest. Among the 81 species occurring in both forest types, 18 species had significantly higher numbers of contacts in the riparian forest while only 8 species had significantly higher numbers of contacts in the upland forest. Taking into account the contacts numbers of the species the large frugivores guild was closely associated to the upland forest, while bamboo and vine-tangles insectivore, canopy insectivores, edge omnivores, ground omnivore and midstory insectivores were those more closely related to the riparian forest.

“…As espécies de aves que apresentaram maior valor de IPA em CB2 têm sido mais frequentemente associadas a agrupamentos de bambu do interior de floresta, como Drymophila rubricollis, Conopophaga lineata, Hylopezus nattereri, Synallaxis cinerascens e Hemitriccus diops, de acordo com os estudos de Goerck (1999), Leme (2001), Zimmer & Isler (2003), Fitzpatrick (2004), Volpato et al (2006) e Antunes (2007. Destas espécies, apenas H. nattereri e C. lineata apresentaram IPA similar nas trilhas CB1 e CB2; H. diops e S. cinerascens apresentaram valor de IPA maior na trilha CB2 em relação às outras duas e D. rubricollis foi exclusivamente registrada nessa última trilha.…”

Association of birds to bamboo stands in southern brazilian Atlantic Forest, Londrina, Parana State, Brazil. Bamboo stands have been considered relatively important for a high number of bird species, specially in Amazonia. In the present study variations on the abundance of bamboo associated birds were evaluated in areas with different availability of bamboo Chusquea sp. present inside native forest in the southern portion of the Atlantic Forest, Parana State. Point counts were performed during 25 days in five transects, three in bamboo stands areas and two where this microhabitat was absent; the transects differ in the availability of bamboo. The study areas were the Mata dos Godoy State Park and an adjacent forest fragment, which together sum a total area larger than 2,000 ha, in northern Parana State, southern Brazil. Nineteen bird species were analyzed and only five of them were recorded in the transects where the bamboo was absent. Five bird species decreased significantly their abundances according the decreasing in the availability of bamboo (G-test, P < 0.01). None species had higher abundance in the transects where the bamboo was absent. Differently of Amazonia, bamboo stands in the southern portion of the Brazilian Atlantic forest are not extensive areas; actually, this type of microhabitat is more disperse throughout the understory. Even so, this microhabitat may be important for conservation of certain bird species in the Atlantic forest. Resumo: Agrupamentos de bambu têm sido considerados relativamente importantes para um grande número de espécies de aves, principalmente na Amazônia. No presente estudo avaliamos as variações na abundância de aves associadas ao bambu Chusquea sp. em áreas com diferentes disponibilidades deste microhábitat no interior de floresta nativa, na porção sul da Mata Atlântica, Estado do Paraná. Amostragens por ponto-de-escuta foram realizadas durante 25 dias em cinco trilhas, três em áreas com agrupamentos de bambu e duas em áreas onde este microhábitat estava ausente; as trilhas diferiram na disponibilidade de bambu. As áreas de estudos foram o Parque Estadual Mata dos Godoy e um fragmento florestal adjacente que, juntos, formam uma área maior que 2.000 ha no Norte do Estado do Paraná, Sul do Brasil. Das dezenove espécies de aves analisadas, apenas cinco foram registradas nas trilhas onde não havia bambu. Cinco espécies diminuíram significativamente suas abundâncias de acordo com a disponibilidade decrescente de aglomerados de bambu (teste-G, P < 0,01). Nenhuma espécie de ave apresentou maior abundância nas trilhas onde o bambu estava ausente. Diferente da Amazônia, agrupamentos de bambu na porção sul da Mata Atlântica brasileira não formam áreas extensas, sendo encontrados mais esparsos pelo sub-bosque. Ainda assim, este microhábitat pode ser importante para a conservação de certas espécies de aves na Mata Atlântica. Palavras-chave: aves, bambu, Chusquea, Mata Atlântica.

“…and observed that richness and abundance increased significantly in areas dominated by bamboo and the most common species were Drymophila rubricollis, Conopophaga lineata, Hylopezus nattereri, Synallaxis cinerascens, and Hemitriccus diops. Many other investigators have recorded associations between these species and the presence of bamboo in the forest (LeMe, 2001;fitzpatriCk, 2004;VoLpato et al, 2006;areta et al, 2009). Bamboo specialists were estimated to comprise 5% of the bird community in the Paraná region (anjoS et al, 2007).…”

ABSTRACT. The dynamics of the bird community in a small forest fragment was evaluated along seven years in relation to changes in the surrounding landscape. The study area is an Araucaria forest fragment in Southern Brazil (state of Paraná). The sampling period covered the years 1988 through 1994 and the mark-release-recapture method was utilized. The landscape analysis was based on Landsat TM images, and changes in exotic tree plantations, native forest, open areas (agriculture, pasture, bare soil, and abandoned field), and "capoeira"(native vegetation ≤ 2 m) were quantified. The relationship between landscape changes and changes in abundance diversity of forest birds, open-area birds, forest-edge birds, and bamboo specialists was evaluated. Richness estimates were run for each year studied. The richness recorded in the study area comprised 96 species. The richness estimates were 114, 118 and 110 species for Chao 1, Jackknife 1 and Bootstrap, respectively. The bird community varied in species richness, abundance and diversity from year to year. As for species diversity, 1991, 1993 and 1994 were significantly different from the other years. Changes in the landscape contributed to the increase in abundance and richness for the groups of forest, open-area and bamboo-specialist species. An important factor discussed was the effect of the flowering of "taquara" (Poaceae), which contributed significantly to increasing richness of bamboo seed eaters, mainly in 1992 and 1993. In general, the results showed that landscape changes affected the dynamics and structure of the bird community of this forest fragment over time, and proved to have an important role in conservation of the avian community in areas of intensive forestry and agricultural activities. KEYWORDS.Richness, abundance, diversity, long-term assessment, state of Paraná.RESUMO. Comunidade de aves em um fragmento de floresta de araucária em relação a mudanças na paisagem circundante no sul do Brasil. Este estudo avaliou a dinâmica da comunidade de aves em um fragmento florestal ao longo de sete anos e correlacionou às mudanças ocorridas na paisagem circundante. A área de estudo localiza-se na Região Sul do Brasil (Estado do Paraná) e a vegetação está representada por Floresta Ombrófila Mista. O período de amostragem ocorreu entre os anos de 1988 a 1994 e o método utilizado foi captura-marcação e recaptura. Para análise da mudança no uso e cobertura da paisagem foram utilizadas imagens Landsat TM e um sistema de informação geográfico. Quatro classes foram usadas, sendo: plantios com espécies exóticas, floresta nativa, capoeiras (vegetação nativa < 2 m de altura) e áreas abertas (campo abandonado, pastagens, área agrícola e solo exposto). Foi analisada a relação entre as mudanças na paisagem e as mudanças na abundância e diversidade de aves de floresta, de área aberta, de borda e especialistas de bambu. Foram calculadas as estimativas de riqueza para cada ano estudado. A riqueza registrada na área de estudo foi de 96 espécies e as estimativas foram 114, 118 e ...
