To test if species’ local abundance has an effect on number of collisions at Duke University, we compared the observed rate of collision in each classification category (e.g.,

Only two studies have examined carcass removal by scavengers in an urban environment, and previous estimates of bird-window collision mortality at houses have relied on carcass

HSIANG, the differentiable degree of symmetry S(M) of a smooth manifold M" is defined to be the supremum of dim G where G is a compact Lie group acting smoothly and effectively

Using the so-called Palm measure, we extend the classical result to a stationary point

In this section, we describe how a conjecture of Sakellaridis and Venkatesh on the L 2 spec- trum of symmetric varieties relates to the method we have used in this paper, in

As stakes differ greatly depending on the spe- cies, and as biodiversity management decision- making and policy-making is mostly done locally, when the goal is to accurately

Abstract: This study presents the results of object-based classifications assessing the potential of bi- temporal Pléiades images for mapping broadleaf and coniferous tree

The global idea of the risk assessment is to have a pseudo-continuous evolution of the probability of collision on the whole prediction horizon so that it possible for a
