Identifying taxonomic distribution of such coping strategies is fundamental to evolutionary models and to management of captive animals. Capuchin monkeys...
The effects of metabolic cage housing and sex on cognitive bias expression in rats
Contributor(s):: Barker, T. H., Howarth, G. S., Whittaker, A. L.
The use of metabolic cages is established housing protocol in small-animal, gastrointestinal research. Physiological data, as primarily observed through secretions of the hypothalamic-pituitary-adrenal axis has shown that rodents housed in this manner experience an increased stress response. Few...

Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study...
Gender and power in narratives of "Natural Horsemanship": the production of "prey-identified masculinity"
| Contributor(s):: Tom, E.
It is widely recognized by equestrians that Natural Horsemanship has helped to create better lives for horses, but what are the effects of the discipline among humans? The narratives of the leading exponents of Natural Horsemanship, Monty Roberts and Buck Brannaman, use ethological language to...
Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy
| Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.
This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...
Of cows and women: gendered human-animal relationships in Finnish agriculture
| Contributor(s):: Kaarlenkaski, T.
