The role of maternal hormones in avian sex ratio manipulation
Meeting Abstract S5-1.4 Saturday, Jan. 5 The role of maternal hormones in avian sex ratio manipulation GROOTHUIS, T.G.G.*; GOERLICH, V.C.; DIJKSTRA, C.; University of Groningen, NL; University of Bielefeld D; University of Groningen, NL a.g.g.groothuis@rug.nl Avian species can manipulate the sex ratio of their offspring before these offspring hatch. In birds, mothers can not only affect the […]
Targets for hormone-mediated sex ratio adjustment in vertebrates
Meeting Abstract S5-1.1 Saturday, Jan. 5 Targets for hormone-mediated sex ratio adjustment in vertebrates CREWS, D; University of Texas at Austin crews@mail.utexas.edu When considering sex ratios, we have to first define the nature of the question. Are we speaking of the gonads, secondary and accessory sex structures, physiology, brain, behavior, or all of the above elements. If […]
Stress, hormones, and sex How do we solve the puzzle of sex ratio adjustment in birds
Meeting Abstract S5-1.3 Saturday, Jan. 5 Stress, hormones, and sex: How do we solve the puzzle of sex ratio adjustment in birds? NAVARA, KJ; Univ of Georgia knavara@uga.edu Ecologists and evolutionary biologists have shown time and again that birds have a striking ability to vary the ratios of male and female offspring they produce in response to […]
From emergence to evolution Phenotypic integration of complex offspring sex-bias
Meeting Abstract S5-1.5 Saturday, Jan. 5 From emergence to evolution: Phenotypic integration of complex offspring sex-bias BADYAEV, A.V.; Univ. Arizona abadyaev@email.arizona.edu Sex-bias in egg-laying order is a seemingly evolutionary impossible combination of precision, complexity, context-dependency, and reversibility. Yet, it is a common occurrence and a frequent starting point for a wide range of adaptive ecological and evolutionary […]
Early hormonal influences on temperature dependent sex determination in turtles
Meeting Abstract S5-1.2 Saturday, Jan. 5 Early hormonal influences on temperature dependent sex determination in turtles BOWDEN, R.M.*; CLAIRARDIN, S.G.; PAITZ, R.T.; Il. St. Univ.; Il. St. Univ.; Il. St. Univ. rmbowde@ilstu.edu In reptiles with temperature dependent sex determination (TSD), treatment with exogenous steroids, particularly estrogens, during the middle third of development have well documented effects on […]
