The patterns of genetic variation of present-day European terrestrial fauna and flora have been influenced by repetitive fluctuations between major glacial and interglacial climatic cycles that have occurred during the Quaternary period (Hewitt, 2004, and references therein). The isolation of species into one or more refugia during the glaciations (Hewitt, 1996) and the mode of post-glacial col...
The aim of this study was to measure the relative susceptibility of three age classes of red deer (Cervus elaphus) to the various manifestations of infection and disease states due to Mycobacterium avium subsp. paratuberculosis (MAP) after experimental oral challenge. Three groups of seronegative female deer (30 three-month-old weaners, 20 fifteen-month-old yearlings and 20 adults) received fou...
Previous investigations on the karyotype of Cervus dama L. used conventional staining techniques (Gustavsson 1965; Hsu and Benirschke 1967; Wurster and Benirschke 1967; Gustavsson and Sundt 1968) and found a somatic, diploid chromosome number of 2n = 68, XX resp. XY. More recently, fluorescence and banding techniques which allow to differentiate between single chromosomes were used by Neitzel (...
Zooarchaeological and paleoecological investigations have traditionally been unable to reconstruct the ethology of herd animals, which likely had a significant influence on the mobility and subsistence strategies of prehistoric humans. In this paper, we reconstruct the migratory behavior of red deer (Cervus elaphus) and caprids at the Pleistocene-Holocene transition in the northeastern Adriatic...
Outdoor recreation has the potential to impact spatial and temporal distribution of animals. We explore interactions between red deer Cervus elaphus hikers along a popular hiking path in Scottish Highlands. placed camera traps transects at different distances (25, 75 150 m) from study whether distance hiker activity influences number detected. compared this with detection an additional, spatial...
The overabundance of large herbivores is now recognized as a serious ecological problem. However, the resulting ecological consequences remain poorly understood. The ecological effects of an increase in sika deer, Cervus nippon Temminck (Cervidae), on three insect groups of beetles was investigated: ground beetles (Carabidae), carrion beetles (Silphidae), and dung beetles (Scarabaeidae and Geot...
