Guano arthropod assemblages in caves of Mabini, Pangasinan (Philippines)
2019
Encinares, J.M.A.
This study documented the guano arthropod communities inside Cacupangan, Timori, Santo Rosario and Cabalyorisa Caves in Mabini, Pangasinan [Philippines] in terms of taxonomic composition, density, and distribution within guano deposits. Several types of guano with their unique assemblages of associated arthropods were observed. Even the same type of guano supported different assemblages in different caves. A total of 42 morphospecies belonging to at least six classes were recorded, including three possible new cave-restricted species a tarantula from Timori Cave (Orphnaecus sp.), and a troglomorphic millipede found in all four caves (Haplodesmidae). Swiftlet guano deposits were found to contain more arthropod taxa than bat guano. It was also found that the abundance of arthropods decreased with guano depth, but taxon richness did not significantly differ with depth.
