Item type: Journal Article • Journal: Journal of Endocrinology, Metabolism and Diabetes of South Africa • Authors: H Atmaca --- Department of Endocrinology and Metabolism, Turkey F Gokosmanoglu --- Department of Endocrinology and Metabolism, Turkey EK Kan --- Department of Endocrinology and Metabolism, Turkey GC Ecemis --- Department of Endocrinology and Metabolism, Turkey CT Bahadir --- Department of Endocrinology and Metabolism, Turkey -
Secondary dyslipidaemia
Item type: Journal Article • Journal: South African Family Practice • Authors: DJ Blom --- Division of Lipidology, Department of Medicine,Plasma lipid levels are determined by the interplay of environmental and genetic factors. Occasionally environmental factors may alter lipid levels significantly, resulting in secondary dyslipidaemia. The lipid phenotype in secondary dyslipidaemia is very variable (e.g. predominant hypercholesterolaemia, hypertriglyceridaemia or changes... -

The social correlates of self-directed behaviour and faecal glucocorticoid levels among adult male olive baboons (Papio hamadryas anubis) in Gashaka-Gumti National Park, Nigeria
Item type: Journal Article • Journal: African Zoology • Authors: Jacklyn J. Ellis --- Centre for Research in Evolutionary Anthropology, Roehampton University, U.K. Ann M. MacLarnon --- Centre for Research in Evolutionary Anthropology, Roehampton University, U.K. Michael Heistermann --- Reproductive Biology Unit, German Primate Centre, Germany Stuart Semple --- Centre for Research in Evolutionary Anthropology, Roehampton University, U.K.Sociality confers many benefits to gregarious animals, but group-living does not come without associated costs. Social living can cause anxiety, which if prolonged can lead to stress. We investigate correlates of anxiety and stress among wild adult male olive baboons... -
From killer to carer: steroid hormones and paternal behaviour
Item type: Journal Article • Journal: African Zoology • Authors: Ruan de Bruin --- Mammalian Cognition Research Group, Department of Zoology and Entomology, South Africa Andre Ganswindt --- Department of Anatomy and Physiology, Faculty of Veterinary Science, South Africa Aliza le Roux --- Mammalian Cognition Research Group, Department of Zoology and Entomology, South AfricaMammalian parental investment (i.e. care of descendant offspring) is largely biased towards maternal contributions due to the specific feeding needs of mammalian offspring; however, varying degrees of paternal investment have been reported in about 10% of all mammalian species. Within... -
Hot and bothered: alterations in faecal glucocorticoid metabolite concentrations of the sungazer lizard, Smaug giganteus, in response to an increase in environmental temperature
Item type: Journal Article • Journal: African Zoology • Authors: J Scheun --- , South Africa R Campbell --- , South Africa A Ganswindt --- , South Africa T McIntyre --- , South AfricaDespite the commonly held belief that reptiles are immune to extreme temperatures, global warming is predicted to result in the loss of 40% of all reptile species by 2080. In order to understand the effects of elevated temperature on African...
