The ability to predict spatial patterns of species richness using a few easily measured
environmental variables would facilitate timely evaluation of potential impacts of …

One of the major determinants of species richness is the amount of energy available, often
measured as primary productivity. Heterogeneity of environmental variables has also been …

Values of species richness are used widely to establish conservation and management
priorities. Because inventory data, money, and time are limited, use of surrogates such as …

Aim We examined whether variation in species composition of breeding birds and resident
butterflies in the Great Basin of North America depended on sampling grain (the smallest …

Birds are commonly used as bio-indicators of the quality of environments and the changes to
them. Therefore, ecologists put a lot of effort into the monitoring of their population trends …

Urbanization changes bird community structure during the breeding season but little is
known about its effects on migrating birds. We examined patterns of habitat use by birds at …

Much of metapopulation theory assumes that the persistence of individual populations in a
metapopulation, and persistence of the metapopulation as a whole, is best modeled by the …

Over the next half century the human population is expected to grow rapidly, resulting in the
conversion of rural areas into cities. Wetlands in these regions are therefore under threat …

We used nested subsets analysis to examine distribution patterns of birds and butterflies in
the same set of 83 locations in canyons of three mountain ranges in the Great Basin of …

We provide an overview of how nestedness analyses of presence/absence data might direct
conservation and land-use planning in developing landscapes. We describe two …
