Behavioural and physiological responses of chacma baboons ( Papio ursinus ) to human‐induced mortality in anthropogenically modified habitat
As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between humans and wildlife. In some cases, this conflict can result in permanent injuries or mortality of animal…
Experiences of first-generation scholars at a highly selective UK university
Targets set by the UK Office for Students require highly academically selective UK universities to enrol a greater percentage of students identified as least likely to participate in higher education. Such students are typically at a disadvantage in terms of levels of academic preparedness and economic, cultural and social capital. Drawing on eighteen interviews with first-generation students at Durham University, we identify five sites of pressu…
Variation in Paranasal Pneumatisation between Mid-Late Pleistocene Hominins
There is considerable variation in mid-late Pleistocene hominin paranasal sinuses, and in some taxa distinctive craniofacial shape has been linked to sinus size. Extreme frontal sinus size has been reported in mid-Pleistocene specimens often classified as Homo heidelbergensis, and Neanderthal sinuses are said to be distinctively large, explaining diagnostic Neanderthal facial shape. Here, the sinuses of fossil hominins attributed to several mid-l…
Implications of Tourist–Macaque Interactions for Disease Transmission
During wildlife tourism, proximity or actual contact between people and animals may lead to a significant risk of anthropozoonotic disease transmission. In this paper, we use social network analysis, disease simulation modelling and data on animal health and behaviour to investigate such risks at a site in Morocco, where tourists come to see wild Barbary macaques (Macaca sylvanus). Measures of individual macaques' network centrality-an index of t…
Correlates of androgens in wild male Barbary macaques
Investigating causes and consequences of variation in hormonal expression is a key focus in behavioral ecology. Many studies have explored patterns of secretion of the androgen testosterone in male vertebrates, using the challenge hypothesis (Wingfield, Hegner, Dufty, & Ball, 1990; The American Naturalist, 136(6), 829-846) as a theoretical framework. Rather than the classic association of testosterone with male sexual behavior, this hypothesis pr…
Foraging with finesse
OBJECTIVES: Fruit husks are rarely uniformly hard, varying in penetrability via sulci and changes in thickness. We tested whether a hard-food specialist primate i) bites randomly on food fruit husk surfaces to access seeds, or ii) selects areas most easily penetrated by canines. We consider this would occur so as to minimize deployed mechanical force, energetic expenditure and risk of dental breakage when feeding. METHODS: A sulcus is the natural…
Personality Traits in Rhesus Macaques (Macaca mulatta) Are Heritable but Do Not Predict Reproductive Output
Arthropod Predation by a Specialist Seed Predator, the Golden-backed Uacari (Cacajao melanocephalus ouakary, Pitheciidae) in Brazilian Amazonia
Sleeping site selection by golden-backed uacaris, Cacajao melanocephalus ouakary (Pitheciidae), in Amazonian flooded forests
Terrestrial Activity in Pitheciins ( C acajao , C hiropotes , and P ithecia )
Neotropical monkeys of the genera C acajao , C hiropotes , and P ithecia ( P itheciidae) are considered to be highly arboreal, spending most of their time feeding and traveling in the upper canopy. Until now, the use of terrestrial substrates has not been analyzed in detail in this group. Here, we review the frequency of terrestrial use among pitheciin taxa to determine the ecological and social conditions that might lead to such behavior. We col…
Living on the edge
Baboons are the most successful and ubiquitous African primates, renowned for their behavioral and reproductive flexibility, which enable them to inhabit a wide variety of habitat types. Owing to a number of long‐term field studies, comparative behavioral, developmental, demographic, and life‐history data are available from several populations, but study sites show a heavy bias toward South and East African savannahs, with little research in West…
Sexual Skin Color Contains Information About the Timing of the Fertile Phase in Free-ranging Macaca mulatta
The timing of ovulation with respect to sexual swelling detumescence in wild olive baboons
The comparative method
Introduction There are two major means of investigation across a wide range of sciences, both natural and social. These are the experimental method and the comparative method. In the so-called hard sciences – physics and chemistry – and also the ‘harder’ end of biology, investigation is more commonly by experimental manipulation. Other biological questions, notably those concerning evolutionary history and adaptation, are more or less inaccessibl…
The evolution of human speech
Many cognitive and physical features must have undergone change for the evolution of fully modern human language. One neglected aspect is the evolution of increased breathing control. Evidence presented herein shows that modern humans and Neanderthals have an expanded thoracic vertebral canal compared with australopithecines and Homo ergaster, who had canals of the same relative size as extant nonhuman primates. Based on previously published anal…

Gastrointestinal Allometry in Primates and Other Mammals
Personality and IQ score variation in a Cambridge undergraduate sample
This study, using an undergraduate sample, examines the relationship between ten independent variables and their interactions, on two IQ components and sixteen personality factors. There was a highly significant relationship between both IQ components and subject studied at university, and between the verbal IQ component and birth order. A relationship between smoking habit and personality was also found.
