Given S1, a finite set of points in the plane, we define a sequence of point sets Si as follows: With Si already determined, let Li be the set of all the line segments connecting pairs of points of ⋃i j=1 Sj , and let Si+1 be the set of intersection points of those line segments in Li, which cross but do not overlap. We show that with the exception of some starting configurations the set of all...

Variation in the size and overlap of space use by white-tailed deer (Odocoileus virginianus) has broad implications for managing deer–human conflicts and disease spread and transmission in urban landscapes. Understanding which factors affect overlap of home range by various segments (i.e., age, sex) of an urban deer population has implications to direct contact between deer on disease epidemiol...

wild goat (capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in iran. however, few studies on the relationship between this species and its habitat have been conducted. this species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. in this study which lasted from fall 2009 through summer 2011, seasonal ...
