Birth sex ratio in captive mammals: Patterns, biases, and the implications for management and conservation
Abstract 10.1002/(SICI)1098-2361(2000)19:13.3.CO;2-M Sex allocation theory predicts that a female should produce the offspring of the sex that most increases her own fitness. For polygynous species, this means that females in superior condition should bias offspring production toward the sex with greater variation in lifetime reproductive success, which is typically males. Captive mammal populations are generally […]
F10 pandalid shrimp: Sex determination; DNA and dopamine as indicators of domestication; and outcrossing for wild pigment pattern
Abstract 10.1002/zoo.1430120506.abs Domestication becomes significant in captive propagation of high-fecundity animals which sustain significant mortality rates. The domestication process typical of higher vertebrates has been observed in the coonstripe shrimp, Pandalus danae, which were reared through 10 generations for study of protandric hermaphroditism. The research protocol of repeated handling, for determining sex and carapace length, […]
