Total seven individuals, ranging in number from1 to 3 individuals were encountered between 2065 m and 2365 m asl with population density of 2.6 birds/km2 and calling site density of 1.2 calling sites/km2 (Table 1). DISTRIBUTION AND POPULATION STATUS OF HIMALAYAN MONAL PHEASANT (LOPHOPHORUSIMPE...
* The state of Texas contains 0.46% of the world’s total land area and has a population density of about 117 people per square mile.[20] If everyone in the world moved to Texas, the population density would be 31,079 people per square mile. This is 3% below the population density of...
The minimum population density estimate was higher than previous studies in northern England but substantially lower than those reported in Scotland (18.2 bats km-2). The combined density of M. mystacinus, M. brandtii, and P. pipistrellus, which have similar foraging styles (15.8 bats km2), ...
3. Overall, these results illustrated the dependency of GPS on the density of the reference population data set and indicated that accuracy improves with the inclusion of additional populations residing in geographically distant or isolated regions. GPS applicability using a thinner marker set. PC-...
Gridded Population of the World (GPW) v4 (ref. 11) uses this methodology at 30 arc-seconds (approximately 1 km resolution at the equator) resolution, a dataset which details population count and density. The areal-weighting approach does not use additional data to allocate the population ...
Initially, the size of territories decreased as their density increased, but after density stabilized, median territory area was 0.6 km2. The ranges of up to four released females were centred on each territory and female core areas were arranged in clusters along the wadi. Female ranges became ...
D = N/2LW, where D = estimated density of animals in each habitat, N = number of animals seen, L = length of transect lines and W = mean perpendicular distance of animals seen. The population sizes of animals in each habitat were estimated by multiplying the population density (D) ...
The paucity of basic information is a major obstacle to developing an effective conservation strategy in this region. Using camera-trapping techniques and capture-recapture population estimation models, this study provided the first statistically valid model-based density estimates of tigers in Taman ...
