For Syrmaticus ellioti , the total habitat area was about 52.8115km2 (48.5%), and the areas of broad-leaved forest, mixed forest and coniferous forest were 28.5429km2, 13.5831km2 and 10.7035km2 separately.
Instream Flow Incremental Methodology (IFIM) has been developed to assist decision-making in river system planning, protection and management. The methodology consists of a series of hydraulics, water quality, hydrology and ecology models as well as various methods for simulating quantitative relationships between the discharge and 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.
