- Timing and synchrony of ovulation in red deer constrained by short northern summers
Norwegian Institute for Nature Research, Tungasletta 2, N 7005 Trondheim, Norway
Am Nat 163:763-72. 2004
..Our findings suggest, therefore, that mothers unable to ovulate before a certain date fail to do so altogether that year...
- The timing of male reproductive effort relative to female ovulation in a capital breeder
Centre for Ecological and Evolutionary Synthesis CEES, Department of Biology, University of Oslo, PO Box 1066 Blindern, N 0316 Oslo, Norway
J Anim Ecol 77:469-77. 2008
..Male rutting phenology is thus best interpreted as a compromise between hitting peak female ovulation and intensity of sexual selection...
- Social rank, feeding and winter weight loss in red deer: any evidence of interference competition?
Norwegian Red Deer Center, 6914 Svanøybukt, Norway
Oecologia 138:135-42. 2004
..Our study therefore underlines that, although frequent aggression is observed at artificial feeding sites of northern herbivores, this is not necessarily sufficient to give rise to interference competition...
- Hierarchical path analysis of deer responses to direct and indirect effects of climate in northern forest
Centre for Ecological and Evolutionary Synthesis CEES, Department of Biology, University of Oslo, PO Box 1066, Blindern, 0316 Oslo, Norway
Philos Trans R Soc Lond B Biol Sci 363:2359-68. 2008
..No solid evidence of direct effects of snow depth was found on autumn body mass. We discuss the implications of our results relative to our ability to predict effects of global change on large mammalian herbivores in the boreal forest...
- Testing five hypotheses of sexual segregation in an arctic ungulate
Leif Egil Loe
Centre of Ecological and Evolutionary Synthesis, Department of Biology, University of Oslo, PO Box 1066 Blindern, N 0316 Oslo, Norway
J Anim Ecol 75:485-96. 2006
..Several mechanisms are thus interacting to explain the full-year pattern of sexual segregation and the combination of mechanisms varies among species and populations...
- Increased effect of harsh climate in red deer with a poor set of teeth
Leif Egil Loe
Centre for Ecological and Evolutionary Synthesis CEES, Department of Biology, University of Oslo, P O Box 1066, Blindern, 0316 Oslo, Norway
Oecologia 147:24-30. 2006
..This study indicates that a well-functioning set of teeth is essential for mammal performance, and that selection pressure against (dental) anomalies is more pronounced when climate is unfavorable...
- Importance of climatological downscaling and plant phenology for red deer in heterogeneous landscapes
Department of Biology, University of Oslo, Centre for Ecological and Evolutionary Synthesis, CEES PO Box 1066, Blindern, N 0316 Oslo, Norway
Proc Biol Sci 272:2357-64. 2005
..Our results emphasize the importance of incorporating spring as well as the interaction between winter climate and topography when aiming at understanding how plant and animal respond to climate change...
- Multiple causes of sexual segregation in European red deer: enlightenments from varying breeding phenology at high and low latitude
UMR 5558 Biométrie et Biologie Evolutive, Universite Claude Bernard Lyon 1, 43, Boulevard du 11 Novembre 1918, 69622 Villeurbanne Cedex, France
Proc Biol Sci 271:883-92. 2004
..We conclude that latitude-dependent breeding phenology shapes the seasonal pattern of sexual segregation and that sexual segregation in ungulates has multiple causes...
- Decelerating and sex-dependent tooth wear in Norwegian red deer
Leif Egil Loe
Department of Biology, Division of Zoology, University of Oslo, P O Box 1050 Blindern, 0316, Oslo, Norway
Oecologia 135:346-53. 2003
..Earlier reports in the literature of a positive correlation between tooth height and body weight may therefore be due to initial size differences rather than differences in condition due to tooth wear...
- Age- and density-dependent reproductive effort in male red deer
Nigel G Yoccoz
Department of Biology, Division of Zoology, University of Oslo, PO Box 1050 Blindern, N 0316 Oslo, Norway
Proc Biol Sci 269:1523-8. 2002
..The pattern of reproductive effort in males with regard to age and density therefore differs markedly from the pattern reported for females...
