碩士 / 國立臺灣師範大學 / 生物學系 / 84 / The resource partitioning of frog community in Fu-shan
botanical gardenwas investigated from December, 1994 to April,
1996. Total 11 species of frogs wasrecorded during the study
period. The niche breadth and the nivheoverlap among8 common
species were calculated. Buergeria robusta, Rhacophoru
smoltrchtiand Rhacophorus smaragdinus were present only in small
numbers. Their data were not analyzed. Considering the
clustering analysis, two groups of frogs in thiscommunity can be
identified. Haly chinesis, Chirixalus idiootocus, Polypedates
megacephalus and Rhacophours taipeianus are arboreal species.
Rana adenopleura,Rana kuhlii, Rana latouchii and Bufo
bankorensis are terrestrial species. In terrestrial group, the
temporal niche breadth of Rana kuhlii was 0.382. The standard
habitat niche breadth of Rana adenopleura was 0.649. The habitat
niche breadth of Rana latouchii was 0.412. In arboreal group,
the temporal niche breadth of Polypedates megacephalus was
0.265, the habitat niche breadthChirixalus idiootocus was 0.487
and the niche breadth of roost height of Hyla chinesis was
0.241. These results suggest one species in a group had a large
niche breadth in one particular resource by comparing with other
frogs.Indexes of niche overlap indicate that the overlapping in
temporal, climate and macrohabitat aspests between Rana
latouchii and Rana kuhlii were largerthen 0.42, while the roost
site overlap was very small(0.113). Similarly, the macrohabitat,
roost site and roost height overlaps between
Polypedatesmegacephalus and Rhacophours taipeianus were higher
then 0.813. The in time aspect overlap was small(0.274). The
niche breadth of one species could beeffected by the appearance
of anoyher species. Results from analysis of vertical
distribution (space and time nivhe dimensions), habitats and
diet characteristics indicated that resourcepartitioning among
frogs in Fu-shan botanical garden was clearly seen. In this
pond community, species with broader nivhe, also has a greater
total biomass. Polypedates megacephalus and Rana adenopleus both
have thebroadest niche either in arboreal or terrestrial groups,
they also have thelargest amount in total biomass(5863g,82533g).
