The use of movement data as an assay of habitat quality
Oecologia, 1995Based on our observations and those of others from the literature, we construct a graphical model of habitat use in territorial species at high densities relative to optimal habitat availability. This model ignores differences in abundance among habitats, and, together with other models of habitat use, predicts that there should be greater stability ...

Distinguishing individual quality from habitat preference and quality in a territorial passerine
Ecology, 2014Theory predicts that animals breeding in heterogeneous landscapes preferentially occupy habitats likely to maximize individual fitness, but identifying those habitats has proved problematic. Many studies develop metrics of habitat quality linked to site‐specific reproductive output measured in successive years, but few separate the independent effects ...

Habitat preservation and restoration: Do homebuyers have preferences for quality habitat?
Ecological Economics, 2009Abstract This research examines homebuyers' preferences for nearby riparian habitat, an important issue because quality riparian habitat competes for water resources with other activities in semi-arid regions and because federal and local governments allocate significant resources to riparian habitat preservation and restoration plans.

Using habitat quality indicators to evaluate the success of freshwater habitat improvements
Environmental ReviewsDespite freshwater ecosystems being critically important, they have been severely degraded such that freshwater biodiversity losses have been widely documented. To mitigate this loss, many attempts to improve freshwater habitats have been undertaken using various techniques such as those related to restoration and rehabilitation.

Predicting Habitat Quality for Grassland Birds Using Density-Habitat Correlations
The Journal of Wildlife Management, 1986Predictive models relating densities of 5 grassland bird species to habitat variables were developed and tested using stepwise multiple regression and principal components regression. For most species the models gave poor quantitative estimates. Because there were distinct habitat differences among the study sites used to generate and the study sites ...

The quality of coppice woods as habitats for invertebrates
1992The relative merits of coppicing for many woodland invertebrates other than butterflies is poorly understood, this is probably due to the large number of species involved. However, some studies have been published (Welch,1968,1969,1978;Duffey, 1975;Steel and Mills, 1988;Sterling and Hambler, 1988;Waring, 1988;Hill et al., 1990).

Habitat selection by 2 species of nectarivore: habitat quality isolines
1992I present a model predicting the distribution and abundance of two species of competing nectarivore exploiting nectar in two types of flower. The model uses a submodel of resource renewal and depletion, and the principle that individuals attempt to maximize individual fitness, to construct habitat isolines.
