Evolutionary biologists have long been fascinated by extravagant male traits that abound across the animal kingdom and yet convey no apparent benefits to survival. From isopods to elephants, from armaments to ornaments, researchers have spent decades studying male-male competition and female mate choice in an effort to understand the significance of these(More)
We describe eight novel microsatellite loci for the tui, Prosthemadera novaeseelandiae, and the cross-amplification of six polymorphic loci developed for the bellbird (Anthornis melanura). Fifty tui samples from Tawharanui Regional Park, New Zealand, were genotyped using the 14 loci described. Numbers of alleles ranged from 3 to 16. Observed and expected(More)
The objective was to evaluate the survival of Mycobacterium paratuberculosis (Map) in naturally infected dairy cows feces under long periods of freezing at -18°C and -70°C. Samples were collected from cows previously tested positive with serum ELISA or fecal culture, or with clinical signs of Johne's disease. Samples were stored at -18°C and/or -70°C and(More)
