Meeting Abstract 65.2 Sunday, Jan. 6 Placental ontogeny of two species of biennially reproducing snow skinks (Scincidae: Niveoscincus) STEWART, J. R.*; THOMPSON, M. B.; East Tennessee State University; University of Sydney stewarjr@etsu.edu Viviparity and placentation have evolved in numerous lineages of squamate reptiles, yet only five of these are substantially placentotrophic. One of these lineages, the scincid […]

Experimental egg removal reveals costs of reproduction in a lizard, Anolis sagrei
Meeting Abstract 65.1 Sunday, Jan. 6 Experimental egg removal reveals costs of reproduction in a lizard, Anolis sagrei COX, Robert M*; CALSBEEK, Ryan; Dartmouth College; Dartmouth College robert.m.cox@dartmouth.edu Life history theory is structured around the assumption that current reproductive investment incurs costs (e.g., reduced survival or growth) that compromise future reproduction. Despite the theoretical importance of such […]

Hypoxia alters gonadal androgen synthesis in the estuarine fish Fundulus grandis
Meeting Abstract 65.5 Tuesday, Jan. 6 Hypoxia alters gonadal androgen synthesis in the estuarine fish Fundulus grandis CHEEK, A.O.; Houston Baptist Univ. acheek@hbu.edu Estuarine and coastal hypoxic zones are increasing in frequency, duration, and area worldwide. The sub-lethal impacts of prolonged hypoxia on fish are predicted to include loss of habitat, suppressed growth, and impaired reproduction. In […]
