Phytoplankton composition and diversity in response to abiotic factors in Lake Buhi, Camarines Sur, Philippines
Phytoplankton were collected from eight sampling stations around Lake Buhi (Camarines Sur, Philippines) in September and November 2013. The eight sites represented varied zonation and resource uses. A total of 29 species were identified belonging to five major taxonomic groups: the diatoms (Heteroko...
