Creating a Homogeneous Avifauna
2001I compared birds on urban gradients in two ecoregions of the United States by censusing summer resident bird populations at six sites in central California’s coastal chaparral and southwest Ohio’s eastern broadleaf forest. These sites represented comparable gradients of urban land-use which ranged from relatively undisturbed to highly developed and ...

Enhancing Avifauna in Commercial Plantations
Conservation Biology, 2010Abstract: The occurrence of fauna in commercial plantations is often associated with structural complexity. Through a meta‐analysis, we tested whether the structural complexity of plantations could enhance bird species assemblages and whether bird assemblages respond differently depending on taxonomic ...

Prioritising Avifauna Conservation
Australasian Journal of Environmental Management, 2000How should bird conservation efforts be prioritised? This article reviews two approaches—the Collar et al. (1994) global study of threatened bird species and Garnett's (1992b) analysis for Australia. Each of these studies uses IUCN ‘extinction risk threshold’ criteria to derive conservation ‘hotspots’ where effort should be concentrated.

Hyper-arid, arid and semi-arid ecosystems are characterised by low and unpredictable annual rainfall (Noy-Meir 1973), and by marked variability of all communities in time and space (Polis 1991). Resource peaks are unpredictable in time and space, and unpredictable in quality and quantity.

Density compensation in island avifaunas
Oecologia, 1980This paper analyzes factors which determine the extent of density compensation on islands; i.e., is the summed population density of all species on an island equal to the summed mainland density? A graphical analysis allows quantitative comparisons of density compensation studies.

A number of bird counts have been made on Lake McIlwaine and its shoreline. This paper does not attempt a comprehensive checklist but rather it selects some species and traces changes in their abundance as the lake vegetation and nutrient levels have altered.
