Conserving ecological functions of frog communities in Borneo requires diverse forest landscapes

Recent studies suggest that differences in species composition across habitat types lead to increased multifunctionality on the regional scale. However, data about turnover—and especially complementarity functional composition—across neighbouring from natural communities are rare. We studied frog lowland rainforest Malaysian Borneo and compared functional-trait of different (alluvial forest, limestone kerangas). Forest differed strongly their and, a lesser extent, composition. also combinations frogs directly forest identified six clusters functionally similar species: three were found all types, others absent at least one type. The between resulted high gamma diversity, most this diversity was unique individual types. Moreover, strict separation suggests even cannot easily replace each other case local extinctions. maintenance ecological functions fulfilled by landscape scale therefore requires conservation forest-specific communities.
