Sensory abilities in food localization in four species of African mole-rats with diverse social organization

VITÁMVÁS, Miloš January 2013 (has links)
Until recently, it was assumed that African mole-rats search for food randomly, as it is in concordance with Aridity food distribution hypothesis. However, recent studies indicate that some subterranean rodent species including mole-rats could be able to use plant chemicals (kairomones) for food localization. In my master thesis I conducted a battery of experiments on four mole-rat species to prove, that these species also posses the ability of kairomone guided foraging independently of their social organization.

Organic farming: an institutional ethnography

Wagner, Katherine 29 April 2008 (has links)
This thesis investigates challenges to promoting socially just, locally focused agriculture faced by the organic certification program that now regulates organic farming in British Columbia. This inquiry into how organic certification works is conducted as an institutional ethnography. Institutional ethnography is the methodological foundation of Dorothy Smith’s feminist sociology for people. For the institutional ethnographer, ordinary daily activity is the site for investigation of social organization. Small scale organic farmers who are committed to sustainable, socially and ecologically just agriculture offer a critical standpoint from which to explicate extra-local text mediated ruling relations. This inquiry draws on data from open-ended interviews with farmers and an independent organic certification inspector. From these accounts I begin to address how it is that BC’s organic farming certification program actually enters into and reconstitutes the everyday work of farmers and inspectors. From my findings I argue that corporate interests and a focus on global free trade in organic produce and products increasingly guide the institutional structure of organic certification programs. This in turn moves organic farming out of local, farmer control.
