Temporal Variation in Fitness Components and Population Dynamics of Large Herbivores
TLDR
In large-herbivore populations, environmental variation and density dependence co-occur and have similar effects on various fitness components and how that variability affects changes in population growth rates is examined.
Undesirable evolutionary consequences of trophy hunting
TLDR
Declines in mean breeding values for weight and horn size have declined significantly over time in an evolutionary response to sport hunting of bighorn trophy rams, resulting in the production of smaller-horned, lighter rams and fewer trophies.
The Status of the World's Land and Marine Mammals: Diversity, Threat, and Knowledge
TLDR
A comprehensive assessment of the conservation status and distribution of the world's mammals is presented, compiled by 1700+ experts, to suggest common mechanisms driving diversity and endemism across systems.
Consistency of temperament in bighorn ewes and correlates with behaviour and life history
TLDR
For bighorn sheep, Ovis canadensis, ewes captured as part of a long-term study, behaviour during handling is compared to behaviour in the field and reproductive history, and temperament is domain specific rather than domain general.
Measuring senescence in wild animal populations: towards a longitudinal approach
TLDR
The key challenges facing researchers working to understand senescence in the wild are summarized and two analytical approaches to measure ageing using longitudinal data from wild populations are examined: a jack-knifing approach, well-suited to modelling survival probability, and a mixed-effects model approach.
AGE‐SPECIFIC SURVIVAL IN FIVE POPULATIONS OF UNGULATES: EVIDENCE OF SENESCENCE
TLDR
Age- and sex-specific survival in five populations of three species of ungulates using recent statistical developments of capture-mark-recapture models and long-term data on marked individuals suggests species differences in social behavior may be more important than simply the level of polygyny in explaining sexual differences in survival.
REVIEW: The management of wild large herbivores to meet economic, conservation and environmental objectives
Summary 1. Wild large herbivores provide goods and income to rural communities, have major impacts on land use and habitats of conservation importance and, in some cases, face local or global
Mass‐ and Density‐Dependent Reproductive Success and Reproductive Costs in a Capital Breeder
TLDR
Analysis of data on bighorn ewes found survival of weaned lambs to 1 yr was affected by population density but not by maternal mass or previous reproductive success, and the reproductive cost and somatic costs of reproduction increased.
