Y-chromosomal Markers Suitable for Noninvasive Studies of Guenon Hybridization
We examine previously-published TSPY sequence data to identify synapomorphies useful for tracking Y-chromosomal gene flow between hybridizing guenon species.We then describe a set of PCR primers and protocols that amplify many of these variable sites from feces. Such Y-chromosomal markers are potentially very useful to conservation studies because they may offer an early sign of […]
Hormones as indicators of stress
Animal welfare is of increasing importance and absence of chronic stress is one of its prerequisites. During stress, various endocrine responses are involved to improve the fitness of the individual. The front-line hormones to overcome stressful situations are the glucocorticoids and catecholamines. These hormones are determined as a parameter of adrenal activity and thus of […]
