Red Deer: Behavior and Ecology of Two Sexes
TLDR
Red Deer: Behavior and Ecology of Two Sexes is the most extensive study yet available of reproduction in wild vertebrate and reveals the extent of sex differences in behavior, reproduction, and ecology. Expand
Microsatellites reveal heterosis in red deer
TLDR
It is concluded that in the deer population fitness measures expressed early in life do not show evidence of inbreeding depression, but they do showEvidence of heterosis, possibly as a result of population mixing. Expand
Age, sex, density, winter weather, and population crashes in Soay sheep.
TLDR
This work analyzed the effect of density, extrinsic climatic fluctuations, and demography on the irregular pattern of population crashes of Soay sheep on the St. Kilda archipelago, United Kingdom. Expand
Plant phenology and the benefits of migration in a temperate ungulate
TLDR
Seasonal changes in crude protein content of graminoids and herbs grazed by red deer were monitored and the relationships between protein content, date and altitude were used to estimate the quality of the diet of twelve radio-collared female red deer that migrated to summer ranges in the mountains. Expand
THE ROARING OF RED DEER AND THE EVOLUTION OF HONEST ADVERTISEMENT
TLDR
Red deer stags appear to assess each other on traits which are related to variation in body condition, and this appears to be the case among red deer stag competitors. Expand
Population density affects sex ratio variation in red deer
TLDR
It is shown that the adaptive relationship between maternal dominance and offspring sex ratio previously demonstrated in red deer, where dominant females produced more males, disappeared at high population density. Expand
The logical stag: Adaptive aspects of fighting in red deer (Cervus elaphus L.)
TLDR
Fighting behaviour is sensitive to changes in the potential benefits of fighting: stags fight most frequently and most intensely where potential benefits are high and tend to avoid fighting with individuals they are unlikely to beat. Expand
Climate and population density induce long‐term cohort variation in a northern ungulate
TLDR
The hypothesis that conditions experienced by individuals in their early development will have long-term effects on their life history traits is tested by analysing and contrasting the effects of climate and population density on cohort birth weight, birth date, litter size, age of maturity, survival and fecundity of Soay sheep on the island of Hirta, St Kilda, Scotland. Expand
Climate, plant phenology and variation in age of first reproduction in a temperate herbivore
TLDR
It is argued that retarded phenological development, during periods of cooler weather, enhances diet quality because leaf :stem ratios and digestibility of plant parts decline more slowly, and weight gain during the early summer growth spurt should be rapid during cool May-June weather, increasing the probability of conception in the autumn. Expand
Noise and determinism in synchronized sheep dynamics
TLDR
A nonlinear time-series model shows that part of the required environmental synchronicity can be accounted for by large-scale weather variations and underline the importance of understanding the interaction between intrinsic and extrinsic influences on population dynamics. Expand
