Genimuculata, L. 1% (McDonald et al. 2005). The four species had a similar prevalence. Declines had occurred in this area 5-9 years previously. 5% at >600 m (McDonald et al. 2005). A similar survey at Eungella National Park in east-central Queensland between 1994 and 1998 where declines had occurred in 198511986, revealed an overall prevalence of 15% in 474 samples of six species (Retallick et al. 2004). 4%. Infection levels in males, females and subadults did not differ within a given species, but did vary among species.

2002; Muths et al. 2003). Although B. boreas has declined since the 1970s, an isolated population in the Rocky Mountains had been stable until 1996 when a sudden decline occurred and chytridiornycosis was diagnosed in specimens collected in 1998 and 2000 (Muths et al. 2003). Only 3% survival was recorded between 1998 and 1999 and the population may not persist (Muths et al. 2003). There were no deaths in tadpoles (Muths et al. 2003). Male B. boreas disappeared faster than did females. Males visit breeding sites every season but females may only breed every second to fourth year.
