The use of movement data as an assay of habitat quality

Oecologia, 1995
Based 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 ...

Habitat quality

2006
Abstract The projects reviewed in this chapter take several approaches to the subject of habitat quality, but all focus on food intake rate as the measure of interest. Because of this focus, using feather growth rate was an attractive option. We begin with a project relating territory size to nutritional condition.

Distinguishing individual quality from habitat preference and quality in a territorial passerine

Ecology, 2014
Theory 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 ...

What is habitat quality? Dissecting a research portfolio on shorebirds

2012
It is intriguing that the fourth edition of the main British ecology textbook Ecology: From Individuals to Ecosystems (Begon et al., 2006) does not include habitat selection or habitat choice amongst the keywords in the subject index. What can be found is the word niche.

Habitat quality and reproductive investment in aphids

Ecological Entomology, 1988
ABSTRACT. Genetically identical vetch aphids, Megoura viciae (Buckton), showed a weak but significant positive relationship between reproductive investment (number of ovarioles) and ...

HABITAT QUALITY IN A HOSTILE RIVER CORRIDOR

Ecology, 1999
Stream fish often occur in tributaries at high densities, and dispersal between tributaries must occur through the intervening river, whose attributes may differ from those of the tributaries. In Trinidad, tributaries of the Guanapo River have high densities of a killifish, Rivulus hartii, but the river also contains a strong piscivore that may affect ...

Approaches to classifying benthic habitat quality

Marine Policy, 2008
Abstract Implementing ecosystem-based management requires methods of assessing the quality of habitats to deliver the high-level objective of achieving healthy ecosystems. ‘Habitat’ has been interpreted in different ways and this has confused the debate over which attributes constitute ‘quality’. Three definitions of quality for habitats are advanced:

The quality of coppice woods as habitats for invertebrates

1992
The 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).
