Avifauna en bosques manejados de Pinus patula en la Mojonera, Zacualtipán, Hidalgo
Provedor de dados: 32
Autores: Chi Poot, Roger Antonio.
El presente trabajo se realizó en La Mojonera, Zacualtipán, Hidalgo, con la finalidad de determinar el efecto del manejo del bosque de Pinus patula sobre la riqueza de avifauna, durante la transición invierno-primavera 2004-2005. Se definieron tres condiciones del bosque de acuerdo a su historial de manejo. La Condición Uno (C1) pertenece a un bosque no intervenido por el proceso de corta (bosque natural); la Condición Dos (C2) estuvo constituida  por rodales mayores a 12 años; y la Condición Tres (C3) por rodales menores de 12 años de edad. Para el muestreo de la vegetación, se establecieron 21 parcelas de 400 m2 (20X20m). En cada parcela se etiquetaron todos los individuos de especies arbóreas con DAP≥2 cm. Se identificaron, se registró su DAP, altura,...

Agricultural landscapes as habitat for birds in central Chile

Autores: Muñoz-Sáez,Andrés; Perez-Quezada,Jorge F.; Estades,Cristián F.
Abstract  Background: Understanding the role of agroecosystems as habitat for wildlife is crucial for long-term conservation planning, as different crop stratification and landscape elements can influence bird communities, which are also affected by seasonality. The goal of our study was to determine how agricultural landscapes varying in land cover characteristics affect bird richness and abundance. Bird surveys were conducted at 110 locations within agricultural landscapes in central Chile. The surveyed areas were characterized by land cover at two scales (50 and 500 m radii) through direct observation and photo-interpretation, during winter and spring seasons. Generalized Linear Mixed Models were used to evaluate the effects of different agricultural...

The effects of forest-savanna-grassland gradients on bird communities of Chiquitano Dry Forests domain, in western Brazil
Provedor de dados: 42
Autores: GODOI,MAURICIO N.; SOUZA,EDIVALDO O. DE.
ABSTRACT Different vegetation types are distributed in mountains according to altitude, topography and soil. The composition and structure of bird communities in these areas can change in relation to the vegetation gradient, with particular communities occupying each habitat type. In this study we present the changes in composition, species richness and bird abundance over the gradient of forests, savannas and altitudinal grasslands of Maciço do Urucum, a mountainous region located in the Chiquitano Dry Forests domain in western Brazil. We recorded 165 bird species through qualitative and quantitative methods. Forested savannas, riparian forests and submontane forests presented the highest richness and abundance of birds, while arboreal savannas and...
