“…The remaining species are distributed among 24 different families. Our sample includes 40% of the regional bird species list (16). Species from open fields, inundated areas, and the high canopy are the most consistent absences.…”

In the face of worldwide habitat fragmentation, managers need to devise a time frame for action. We ask how fast do understory bird species disappear from experimentally isolated plots in the Biological Dynamics of Forest Fragments Project, central Amazon, Brazil. Our data consist of mist-net records obtained over a period of 13 years in 11 sites of 1, 10, and 100 hectares. The numbers of captures per species per unit time, analyzed under different simplifying assumptions, reveal a set of species-loss curves. From those declining numbers, we derive a scaling rule for the time it takes to lose half the species in a fragment as a function of its area. A 10-fold decrease in the rate of species loss requires a 1,000-fold increase in area. Fragments of 100 hectares lose one half of their species in <15 years, too short a time for implementing conservation measures.

“…Assim como para outras áreas de alta diversidade, foram necessários vários anos de amostragem para se alcançar a caracterização da avifauna apresentada (Cohn-Haft et al 1997). A avifauna conhecida no interior dessa unidade de conservação totaliza 370 espécies, quando são considerados os registros obtidos e publicados por outros pesquisadores (Antunes et al 2006).…”

“…Ressalte-se que a maior parte da área do PECB ainda não foi amostrada devido a questões pelo Bootstrap e o registro de espécies por outros pesquisadores ou no entorno do parque, apóiam essa constatação. A caracterização da chamada avifauna nuclear é um objetivo mais factível de ser atingido do que um inventário completo (Remsen 1994, Cohn-Haft et al 1997.…”

“…As aves podem ser incluídas nesses programas por serem bem conhecidas e relativamente fáceis de amostrar, quando comparadas a outros grupos de animais. Adicionalmente, listas locais acuradas podem contribuir para ampliar o conhecimento sobre biogeografia e ecologia de comunidades de aves (Cohn-Haft et al 1997). Das unidades do Maciço, Intervales apresenta a avifauna melhor caracterizada, com dados de riqueza e abundância relativa obtidos em estudos de longo prazo (Vielliard & Silva 2001.…”

Abstract:The biodiversity inventory in protected areas from Atlantic Forest can increase knowledge about species distribution and contribute to monitoring and management actions that enhance the ecosystems conservation. Our objectives were to characterize bird assemblages at Carlos Botelho State Park, São Paulo southeastern Brazil, regarding species composition, relative abundance and association with local vegetation types. Sampling was conducted between April 2006 and December 2009 by transects, resulting in 1,000 hours of sampling effort. We recorded 331 species, most showed relative abundance lower than 100 detections. Twenty-five species are threatened in the state of São Paulo.

“…In the Amazon forest, most of the bird species are resident and sedentary (BIERREGAARD 1990a, STOUFFER & BIERREGAARD 1995, COHN-HAFT et al 1997. Therefore, because they have relatively high longevity (SNOW & LILL 1974) and, as a consequence, can learn more about the environment, they may adjust their use of micro-habitat according to local variation in the forest structure.…”

Recently, a significant number of studies on neotropical forest bird communities have focused on factors influencing their richness, abundance, and habitat selection. However, few of them have considered populations or individual species, and how habitat structure affects their distribution and abundance. In this study, we investigated how the combined effects of some forest structure components affect the occurrence and abundance of a resident bird species, the scale-backed antbird Hylophylax poecilinotus (Cabanis, 1847). We tested the null hypothesis of no difference between the variation in forest structure components at locations where birds occurred and at locations where they did not. In a pristine Terra Firme forest at the Ducke Reserve, Manaus, we recorded bird occurrence and abundance using mist nets in 56 transects (1 km long each) within a 9 x 9 km trail grid covering 6400 ha. Also in the same 56 transects, we set 50 x 50 m plots and recorded the following seven components of forest structure and landscape: 1) canopy opening, 2) leaf litter, 3) tree abundance, 4) logs, 5) snags, 6) streams, and 7) elevation. We evaluated their effects on avian occurrence and abundance by using models of Multiple Logistic Regression (for bird occurrence) and Multiple Linear Regression (for bird abundance). The results suggested that H. poecilinotus occurred significantly more often in lowland areas, in areas located farther away from streams, and in areas bearing thicker leaf litter. Hylophylax poecilinotus was also more abundant in lowland areas and in areas located further away from streams. Overall, the results indicated that environmental heterogeneity produced by variation in forest structure components affects habitat use by this bird species in the Amazon forest.
