摘要

Amphibians appear particularly vulnerable to global change as the world enters its sixth mass extinction event (Wake & Vredenburg 2008). Because of their roles as important prey and predators, susceptibility to water-soluble toxins through permeable skin, and a life history that straddles aquatic and terrestrial environments, amphibians are good indicators for environmental degradation and community stability in the face of the major drivers of species loss (Semlitsch 2003). Although the causes of amphibian declines are diverse and interactive (Brook et al. 2008; Sodhi et al. 2008), individual mechanisms include habitat loss (Alford & Richards 1999); environmental contamination (Boone & Bridges 2003); global climate change (Kiesecker et al. 2001); disease and pathogens (Daszak et al. 2003); spread of invasive species (Kats & Ferrer 2003); and overharvesting (Schlaepfer et al. 2005). Here we address the latter category, which, although frequently associated with amphibian declines (Semlitsch 2003), has been poorly quantified (Collins & Storfer 2003; Carpenter et al. 2007). Specifically, we summarize global trade patterns in frogs' legs over a 20-year period and focus on harvesting in Indonesia. We also highlight the need for certification of wild-harvested animals entering international trade to improve monitoring capacity and to aid development of sustainable-harvest strategies.
