The existence of elaborate ornamental structures in males is often assumed to reflect the outcome of female mate choice for showy males. However, female mate choice appears weak in many iguanian lizards, but males still exhibit an array of ornament-like

Changes in parity mode between egg-laying (oviparity) and live-bearing (viviparity) have occurred repeatedly throughout vertebrate evolution. Oviparity is the ancestral amniote state, and viviparity has evolved many times independently within amniotes (especially in lizards and snakes), with possibly a few

The inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1) with (thio)coumarins has been recently reported (Maresca et al., J. Am. Chem. Soc. 2009, 131, 3057). Here we demonstrate that a series of γ- and δ-(thio)lactones also act as
