Influence of Habitat Characteristics on Winter Social

habitat characteristics on winter social organisation in field roe deer. Acta theriol., 34. 14: 219—226 [With 1 Table & 3 Figs]. Winter social structure in field roe deer was compared in three pop-ulations living in haibitaits which differed by wood abundance and distribution. Changes in field attending and grouping tendency (gre-gairiousness and group size) were observed in the three areas: increasing between October and January and decreasing from March forwards. But this seasonal trend was more marked as the habitat was more open (low diversity and high visibility between roe deer). Grouping in open habi-tats can be understood as a way of being protected against predators when shelter is lacking (better detection) or can be supposed to permit control on conspecifics which live in the same area.
