INTRODUCTION Potential causes of the "world-wide amphibian de-
 

Summary: INTRODUCTION
Potential causes of the "world-wide amphibian de-
cline" are still embroiled in controversy (e.g., Alford
& Richards 1999, Houlahan et al. 2000). For some
years now global climatic change has been invoked
to explain the rapid declines in amphibian popula-
tions occurring even in remote and pristine habitats
(e.g., Lips 1999, Carey et al. 2001). Alternatively, syn-
ergisms among an increasing number of local causes
were cited as being responsible for population declines
all over the world (e.g., UV-B radiation, chytridiomy-
cosis, pesticides, habitat destruction; Nyman 1986,
Pechman et al. 1991, Blaustein et al. 1994, Alford &
Richards 1999, Houlahan et al. 2000, Davidson et al.
2002, Ron et al. 2003).
In confronting the decline of amphibian popula-
tions, it becomes increasingly important to recom-
mend conservation priorities, both in terms of species
and areas. Rapid habitat destruction requires a rapid
assessment of community structure, even for areas as
