Abstract:
Energy investment in reproduction is predicted to trade off against other necessary physiological functions like immunity, but it is unclear to what extent this impacts fitness in long-lived species. Among mammals, female primates, and especially apes, exhibit extensive periods of investment in each offspring. During this time, energy diverted to gestation and lactation is hypothesized to incur short and long-term deficits in maternal immunity and lead to accelerated ageing. We examined the relationship between reproduction and immunity, as measured by faecal parasite counts, in wild female ch

Abstract:
The extreme morphological variability of the baculum across mammals is thought to be the result of sexual selection (particularly, high levels of postcopulatory selection). However, the evolutionary trajectory of the mammalian baculum is little studied and evidence for the adaptive function of the baculum has so far been elusive. Here, we use Markov chain Monte Carlo methods implemented in a Bayesian phylogenetic framework to reconstruct baculum evolution across the mammalian class and investigate the rate of baculum length evolution within the primate order. We then test the effects of testes

Abstract:
Although the deliberate creation of human embryos for scientific research is complicated by ethical and practical issues, a detailed understanding of the cellular and molecular events occurring during human fertilization is essential, particularly for understanding infertility. It is clear from cytoskeletal imaging studies of mouse fertilization that this information cannot be extrapolated to humans because of unique differences in centrosomal inheritance. However, the cytoskeletal rearrangements during non-human primate fertilization are very similar to humans, providing a compelling animal m

Abstract:
The epigenetic mechanisms controlling germ cell development and differentiation are still not well understood. Sirtuin-1 (SIRT1) is a nicotinamide adenosine dinucleotide (NAD)-dependent histone deacetylase and belongs to the sirtuin family of deacetylases. It catalyzes the removal of acetyl groups from a number of protein substrates. Some studies reported a role of SIRT1 in the central and peripheral regulation of reproduction in various non-primate species. However, testicular SIRT1 expression and its possible role in the testis have not been analyzed in primates. Here, we document expression

Abstract:
To optimize costs and reproductive success, rhesus macaques in biomedical primate research facilities are often peer-reared. Older, dependent infants are typically removed from their natal group to enhance female reproduction. The minimal husbandry age-norm of infant removal is ten months. These practices deviate from species-specific behavior and may reduce welfare, suggesting a trade-off between female reproduction and welfare. However, the effect of breeding group type and rearing history on female reproductive success (i.e., birth rate; inter-birth interval (IBI); offspring survival) is un

AbstractIt is imperative to provide adequate quantity and quality of space for all captive animals. Yet practically all guidelines on the housing of primates in the laboratory specify minimum cage sizes based solely on body weight. We argue that no single factor, such as body weight, is sufficient to determine cage size. Instead a suite of characteristics should be used that include morphometric, physiological, ecological, locomotor, social, reproductive and behavioural characteristics. Ideally, the primate's age, sex and individual history should also be taken into account. In this paper we c

Abstract:
The placenta of rats and humans share important anatomical similarities, each with a chorio-allantoic, single discoid, haemochorial structure that facilitates highly efficient nutrient transport. Importantly, however, these similarities reflect convergent evolution and conceal markedly different developmental trajectories and endocrine functions. Placental endocrine signals are essential to drive maternal adaptations that facilitate fetal development and ultimately successful birth. Central to these adaptations is a sustained increase in production of the sex steroids progesterone and oestroge

Abstract:
Theoretical models and empirical studies in various taxa have identified important links between variation in sex roles and the number of adult males and females (adult sex ratio (ASR)) in a population. In this review, I examine these relationships in non-human primates. Because most existing theoretical models of the evolution of sex roles focus on the evolutionary origins of sex-biased behaviour, they offer only a general scaffold for predicting variation in sex roles among and within species. I argue that studies examining sex role variation at these more specific levels need to take social

Assisted reproduction technologies (ARTs) are achieving increasing prominence in reproductive medicine. With the increasing application of ARTs comes increased interest in optimizing efficiency while minimizing potential risks to the offspring. One area of assisted reproduction in which improvements are being sought is in vitro oocyte maturation. In vitro oocyte maturation (IVM) holds great promise as a tool for enhancing clinical treatment of infertility, enhancing availability of non-human primates for development of disease models, and facilitating endangered species preservation.

Abstract Traditionally, the marmosets and tamarins have been regarded as monogamous primates which live in extended family units (e.g. Kleiman 1977). However, with increasing knowledge of callitrichid field biology it has become apparent that a single reproductive female may mate with more than one partner (e.g. Callithrix humeralifer: Rylands 1982, 1986a; Saguinus fuscicollis: Goldizen 1987a). This has led to suggestions that ‘facultative polyandry’ may occur; i.e. that two or more males copulate with a single female and co-operate in rearing her twin offspring (Goldizen 1987a; Sussman and Ga
