TLDR
A meta–analysis of previous mammalian sex–ratio studies to determine if there are any overall patterns in sex-ratio variation was confirmed, and showed almost unanimous support for the prediction that mothers in good condition bias their litters towards sons.
Social bonds between unrelated females increase reproductive success in feral horses
TLDR
It is demonstrated that social integration between unrelated females increases both foal birth rates and survival, independent of maternal habitat quality, social group type, dominance status, and age, while controlling for the confounding influence of kinship.
Effects of Helpers on Juvenile Development and Survival in Meerkats
TLDR
It is shown that in wild groups of cooperative meerkats, Suricata suricatta, reductions in the ratio of helpers to pups depress the daily weight gain and growth of pups and thedaily weight gain of helpers.
Estimating Brown Hyaena Occupancy Using Baited Camera Traps
Conservation and management of brown hyaenas (Hyaena brunnea) is hampered by a lack of information on abundance and distribution, which is difficult and labour-intensive to obtain. However, occupancy
Is suckling behaviour a useful predictor of milk intake? A review

  • 1 September 1998
TLDR
The assumption that milk transfer can be measured by time spent suckling has inadequate empirical foundation, and needs to be tested using isotope-labelling methods.
Aging and improving reproductive success in horses: declining residual reproductive value or just older and wiser?
TLDR
Mare age significantly influenced maternal investment in feral horses living on the North Island of New Zealand and older mothers were more likely to foal in consecutive years, supporting the hypothesis that they are investing less than younger mares in individual offspring.
Stallion harassment and the mating system of horses
TLDR
It is proposed that there is strong selection pressure for stable, long-term stallion-mare relationships, called consort relationships, because mares solicit more than one stallion and stallion dominance changes during band formation.
Methods for Locating African Lion Kills Using Global Positioning System Movement Data
TLDR
Implementation of GLMs within an adaptive sampling framework can considerably increase efficiency of locating kill sites, providing a cost-effective method for increasing sample sizes of kill data.
Individual mares bias investment in sons and daughters in relation to their condition
TLDR
Investment by mares who reared both a son and a daughter in different years of the study met the assumptions of the TWH with a minimum of confounding variables, and the predictions of the Trivers-Willard hypothesis are supported.
Factors affecting pup growth and survival in co-operatively breeding meerkats
TLDR
In meerkats, social factors largely, but not wholly, replace the importance of maternal factors that are commonly found to govern reproductive success in non- co-operatively breeding social vertebrates.
