Predicting the seasonal dynamics of bird communities along an urban-rural gradient using NDVI
(Elsevier Science, 2018-04-23)
The normalized difference vegetation index (NDVI) is a strong and widely used proxy for bird species richness in urban environments. However, its potential to predict composition and seasonal dynamics of bird communities ...
Livestock grazing constrains bird abundance and species richness: a global meta-analysis
(Elsevier Gmbh, 2021-11)
Balancing food production and biodiversity conservation is a global challenge today. Livestock grazing is one of the main activities triggering habitat degradation and land-use change around the world. Its effects on ...
Cliff outcrops used as condor communal roosts are local hotspots of occupancy and intense use by other bird species
(Elsevier, 2016-08-01)
Cliff outcrops are structural components of the environment that can maintain a large variety of wildlife; however, they are still rather overlooked in conservation planning. We evaluate whether cliffs used by the Andean ...
Relation between green spaces and bird community structure in an urban area in Southeast Brazil
(2012-03-01)
Increased urbanization typically leads to an increase in abundance of a few species and a reduction in bird species richness. Understanding the structure of biotic communities in urban areas will allow us to propose ...

Bird community composition across an Andean tree-line ecotone
(Wiley, 2012)
Few studies have found strong evidence to suggest that ecotones promote species richness and diversity. In this study we examine the responses of a high-Andean bird community to changes in vegetation and topographical ...
Determinants of bird species richness, endemism, and island network roles in Wallacea and the West Indies: is geography sufficient or does current and historical climate matter?
(Wiley-Blackwell, 2014-11-01)
Island biogeography has greatly contributed to our understanding of the processes determining species' distributions. Previous research has focused on the effects of island geography (i.e., island area, elevation, and ...
Urbanization and the temporal homogenization of bird communities: a case study in central Argentina
(Springer, 2015-05)
Urban expansion to rural and natural areas is a global process. Although several studies have analyzed bird community attributes along urbanization gradients, little is known on the impact of urbanization on temporal ...
