Josefo B. Tuyor, Josef Margraf and Paciencia P. Milan ABSTRACT Decomposition rates of leaf litter in different aquatic ecosystems were compared. Fifty grams of dried talisay (Terminalia catappa L.) leaves placed in small leaf litter bags were used. These were submerged in a river, an estuary and in the sea at ViSCA, Baybay, Leyte, Philippines. …

Josefo B. Tuyor ABSTRACT From March to October. 1993. macroinvertebrate drift patterns in the disturbed stream in Ban Nong Hoi (BNH) and the relatively pristine stream in Doi Chang Kian (DCK), Chiang Mai, Thailand were compared. Results show that day-night changes in drift were mainly controlled by light rather than water temperature. Maximum drift was …

Patria Rosales-Apao ABSTRACT The culture methods of the most economically important seaweeds in the Philippines farmed on a commercial basis such as Eucheuma, Gracilaria and Caulerpa are discussed. Culture methods for each species differ depending on the biology and ecophysiological requirements. Problems associated with seaweed fanning include natural causes such as typhoons, aging effect or …
Hilconida P. Calumpong1 and Ernani G. Meñez2 ABSTRACT Seagrass beds are widespread in Philippine nearshore areas. They are productive, hence, much fishing and gleaning occur. For Enaalus acoroides, growth was reported to reach 2 cm d’i and primary production to 0.92 g C m-2 d1 t. A total of 13 species was recorded. Thalassia hemprichii …
