Relationship between Habitat Quality and Occurrence of the Threatened Black Redhorse
"... Recovery planning for the nationally threatened black redhorse (Moxostoma duquesnei) is limited by a lack of knowledge regarding species ecology, population size and factors that affect distribution and abundance. Generalized additive models (GAM) were used to evaluate the influence of habitat quali ..."

. Habitat quality was found to be associated with the distribution of golden red-horse (M. erythrurum) but not the other two co-occurring redhorse species. Site occupancy was negatively associated with poor substrate and pool conditions. Results from this study indicate that, in areas of black redhorse
Habitat Quality and Geometry Affect Patch Occupancy of Two Orthopteran Species
"... Impacts of habitat loss and fragmentation on distribution and population size of many taxa are well established. In contrast, less is known about the role of within-patch habitat quality for the spatial dynamics of species, even though within-patch habitat quality may substantially influence the dyn ..."

Influence of connectivity, habitat quality and invasive species on egg and larval distributions and local abundance of crucian carp in Japanese agricultural landscapes
"... a b s t r a c t The quality of habitat at and around a spawning site, and the availability of movement between spawning and nonspawning habitats are likely to be important determinants for population persistence in a degraded and fragmented landscape. We assessed the influence of habitat connectivi ..."

2006: Mapping the habitat quality of patch networks for the Marsh fritillary Euphydryas aurinia
- Rottemburg, 1775) (Lepidoptera, Nymphalidae) in
"... Abstract The marsh fritillary is widely distributed in Wales, with over 200 populations identified in the past 15 years. However, agricultural improvement, habitat fragmentation and changes in agricultural practices continue to impact on status and a decline in range of 23.5% was recorded over a 10 ..."

10-year period. Solutions must be applied at the landscape scale to improve metapopulation viability and, since 2000, surveys of habitat extent and quality have been carried out on 116,373 ha of grassland surrounding 111 populations. Analysis of the results for standard 'core landscapes
Models of Regional Habitat Quality and Connectivity for Pumas (Puma concolor) in the Southwestern United
"... The impact of landscape changes on the quality and connectivity of habitats for multiple wildlife species is of global conservation concern. In the southwestern United States, pumas (Puma concolor) are a well distributed and wide-ranging large carnivore that are sensitive to loss of habitat and to t ..."

Original article Investigations on the potential of woodlice as bioindicators of grassland habitat quality
, 2005
"... As intensive land-use practices may reduce available leaf litter, woodliceimportant decomposers of leaf littermay show a loss of biomass and a decrease in number of species. Their diversity as grassland detritivores could thus be a potential guide to ecosystem activity in natural and cultivated gras ..."
