Although goshawks are found in a few other cities, Berlin has the highest density of goshawk territories anywhere in the world – urban or rural.
The population density of each territory depends greatly on food supply and reproductive success, thus the social structure and population density of any given territory is unstable and flexible.
He observed abundant skeletal galls on fossil branches of A. cervicornis that had resulted from the bites of S. planifrons, suggesting that high densities of threespot territories have long been an attribute of Caribbean reef ecology.
The study also did not take into account eagle deaths from the Altamont Pass Wind Resource Area (APWRA), a Northern California wind-energy farm located in an area that supports the world's highest-known density of Golden Eagle nesting territories, according to the Golden Gate Audubon Society.
On the hairy skin of the upper limb, spatial acuity for pain and touch followed opposite proximal distal gradients, consistent with the known innervation density of this body territory.
We have used the criterion of studying the density of cholinergic interneurons in territories that receive only one type of cortical information, in order to minimize the effect of overlapping projections with different cholinergic neuronal densities.
However, the difference in density between the global postcommissural CN (the mean density of all the postcommissural territories of the CN) and the postcommissural Put are only significant but not highly so (Mann-Whitney U; P = 0.024).
The density of main roads within territories averaged 0.19±0.02 km/km, and the maximum distance to main roads ranged from 3.72 to 14.88 km (Table 1).
We also included effects of average water temperature, site, and average density of damselfish within breeding territories as covariates, because these factors may affect larval size (McCormick 2006; Appendix S2, Table B1).
A retention level of about 10% of pre-harvest tree density would almost double the number of territories of resident forest passerines compared to current retention prescriptions.
