J., Smith, T., Hosie, C., Wormell, D., Price, E., & Stanley, C. Historically, I have secured funding for my research from UK research councils (NC3Rs and BBSRC), charities ( Royal Society, UK North of England Zoological Society, UK), academic organizations ( Universities Federation for Animal Welfare, UK Association for the Study of Animal Behaviour, UK), universities ( Queens University of Belfast, University of Chester) and private business ( Disney, USA). In addition to internal collaborations with C Hosie developing welfare assessment tools for amphibians, I collaborate externally with (1) University of Stirling (exploring the possibility of sexually dichromatic pelage colouration functioning as a sexually selected signal in the black-and gold howler Alouatta caraya), (2) Durrell Wildlife Trust (assessing the impact of husbandry routines on levels of excreted cortisol and reproductive hormone metabolites in pied tamarins), (3) Queens university Belfast (addressing the role of badgers in the spread of TB in the cattle population of Northern Ireland investigating behavioural and physiological substrates of temperament in callitrichid primates and researching behavioural and social correlates of HPA activity in captive ring tailed lemurs), (4) University of Veracruz, investigating the link between maternal pregnancy hormones and masculinization of female genitalia in spider monkeys and factors regulating HPA function in captive spider monkeys). I am however still involved in research assessing : (i) internal and extraneous regulation of olfactory communication and (ii) proximate mechanisms regulating reproductive function in social mammals. My main focus is currently assessment of the social and physiological factors that modify hypothalamic pituitary adrenal function (i.e. In parallel with the endocrine work I develop behavioural bioassays, the data from which are combined with the hormone data. I run a productive endocrine laboratory in which we develop and validate enzyme-immunoassays to quantify levels of steroid hormones (cortisol, corticosterone, testosterone, oestrogen and PdG) excreted in a variety of media including urine, faeces, saliva, hair, plasma and the holding water of aquatic species. ![]()
