Wing Ecomorphology and Flight Performance of Bats in Pisan Caves, Kabacan, North Cotabato, Philippines Krizler C. Tanalgo tkrizler@gmail.com University of Southern Mindanao Philippines 1:30 – 1:50 August 17 – Molave Hall This research was conducted to study the functional morphology of the wings and itsflight performance of bats from Pisan caves, Kabacan, Cotabato, Philippines. This was carried out using mist netting method and measurements of basic wing components of bats that includewing span (B), wing area (S) and mass (M). Flight parameters such as aspect ratio and wing loading were derived from the values of wing component and predictions were made using aerodynamic principles. A total of 48 individuals representing eight species were studied. Results showed that Emballonura alecto, Myotis horsfieldii, and Pipistrellus javanicus have an average wing loading and low aspect ratio that indicate an intermediate speed in flight and exceptional maneuverability that is appropriate for catching moving preys in a cluttered environment. High wing loading and low aspect ratio were noted in Cynopterus brachyotis,Eonycteris spelaea, Hipposideros diadema, Rhinolophus arcuatus and Rousettusamplexicaudatus. These values indicate that these bats though fast flyers, have poor maneuverability in terms of flight performance. The study concludes that wing morphology of bats affects flight performance and habitat selection of bats which implies that maintenance of the habitat leads to the stability of the species population.
Some Medicinal Bryophytes Species, their Ethnobotanical Uses, and Morphological Adaptations in Bukidnon Natural Parks, Philippines: A Literature Review Andrea G. Azuelo azuelonenecmu@yahoo.com Central Mindanao University Philippines 1:51 – 2:10 August 17 – Molave Hall Medicinal bryophytes and their morphology features and ethnic uses was examined and documented. Field collections of bryophytes were made through transect walks or floristic survey along the two mountain sites of Bukidnon, namely: Mt. Kalatungan and Mt. Kitanglad. The number of taxa currently determined with medicinal properties was based from the collected species. The species with medicinal uses was generated from a pool of resources, literature review and scientific journals. Description on their morphology characters was made using microscopy examinations. Taxonomic treatment include leaf orientation, stem structure, sporophyte characters and their habit were used to identify into families, genera and species. Species composition between study sites was also compared. Visual habitat as to substrate preference and identification for each species was employed. Results of the study highlights the difference in the morphological features among species of medicinal bryophytes, their ethnic uses, and adaptations within the forested area. Results showed that Mt. Kitanglad exhibited a total of seventeen (17) species of medicinal bryophytes. Of these, eleven (11) are mosses belonging to seven (7) families in eleven (11) genera and six (6) liverworts belonging to five (5) families in six (6) genera; while Mt. Kalatungan exhibited a total of fourteen (14) species of medicinal bryophytes. Of these, eight (8) are mosses belonging to six (6) families in eight (8) genera and six (6) liverworts belonging to five (5) families in six (6) genera. The moss species with medicinal properties belongs to the genus Sphagnum, Polytrichum, Rhodobryum, Fissidens, Bryum, Mnium, Dawsonia, Philonotis, Pogonatum, Barbula and Plagiomnium. The liverworts species include Marchantia, Pallavicinia, Herbertus, Riccardia, Dumortiera and Plagiochila. The species under study exhibited antimicrobial activity, anti-tumor, anti-cancer, antileukemic activity and healing effects based from documented analysis.
