Using Museum Frog Collections to Assign Sex andAge Categories to Frogs in Field Studies: A CaseStudy with the Striped Marsh Frog, Limnodynastes peronii

摘要

In field studies of frogs, assignment of individuals to sex and reproductive age (i.e., immature vs. mature adult) categories is often desirable. For example, differences may exist between these categories in terms of habitat use (Griffin and Case 2001; Proehl 2002), movement patterns (Daugherty and Sheldon 1982; Pilliod et al. 2002; Vasconcelos and Calhoun 2004), survival (Funk and Mills 2003; Lauck 2005), or growth and development (Gramapurohit et al. 2005; Smith and Roberts 2003).
