habitat availability
Our data are consistent with the first hypothesis: the use of pond edges compared to forest and transitional habitats was significantly greater than expected from the habitat availability in the total area and within individual female home ranges.
      
nicholsi appears to be defined by a combination of territorial behavior and dominance relationships among adjacent individuals, permitting the coexistence of all members of the population under circumstances of limited habitat availability.
      
The distribution of the turtles over the continental shelf matched habitat availability, as defined by depth.
      
The spatial distribution of red snapper in the northern Gulf appears to have a complex history that likely reflects glacial advance/retreat, habitat availability and suitability, and hydrology.
      
Habitat availability/suitability and hydrology may partially restrict gene flow among present-day red snapper in the northern Gulf and give rise to a metapopulation structure with variable demographic connectivity.
      
To test whether habitat use determines local and large-scale patterns of abundance of obligate coral-dwelling fishes (genus Gobiodon), the author compared habitat availability with the abundance of four species, G.
      
Habitat availability, measured at tens of meters, explained 47-65% of the variation in abundance of these species among geographic locations spanning over 2,000?km.
      
This enabled us to separate the effects of habitat availability from possible competitive effects.
      
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.
      
In some cases, these three species were also absent from large, nearshore islands with suitable habitat, suggesting that habitat availability was not always responsible for the absence of a species.
      
Observed foraging patterns were compared to the predictions of a statistical model that determined habitat utilization based on habitat availability using a geographic information system (GIS) database.
      
Seasonal variation in the niche, habitat availability and population fluctuations of a bivoltine thermophilous insect near its r
      
Intensified efforts in mussel culturing in the European Wadden Sea during recent decades may have caused an increased abundance of mussel clumps on tidal flats, thus enhancing habitat availability for some mussel-clump inhabitants.
      
We examine patterns of habitat occupancy and habitat availability across sites with a range of population histories to see whether habitat loss is a plausible explanation for these declines.
      
Change in population size between 1980 and 1999 and current habitat availability were weakly correlated in the East Midlands but not in East Anglia.
      
Habitat availability for these species differed between forest types mainly as a result of regular sanitary fellings occurring in managed forests.
      
Integrating landscape connectivity in broad-scale forest planning through a new graph-based habitat availability methodology: ap
      
We describe a new methodology based on graph structures and a habitat availability index (integral index of connectivity) that integrates forest attributes (like habitat quality) and network connectivity in a single measure.
      
We aimed to investigate the diurnal spring habitat selection using Jacobs' second selection index in an intensively cultivated farmland to reveal how the habitat choice by resting hares was affected by changes in the habitat availability.
      
Physical effects of habitat rehabilitation were persistent through time, with pool habitat availability much higher in rehabilitated reaches than elsewhere.
