    A community study of mangroves in Brgy. Caliling, Cauayan, Negros Occidental
    Barredo, Sherry Marie P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-03)
    The species distribution of the mangrove community in Brgy. Caliling, Cauayanz Negros Occidental was studied using the transect line plot method with three plots for each of four stations established. Both stations 1 and 4 were located landward, while stations 2 and 3 were located seaward. Community structure Is described in terms of the following parameters; basal area, number of trees per hectare, importance value, relative density, relative frequency, frequency of species and relative dominance. Variations in these parameters are correlated with physico-chemical factors such as the air, water and soil temperature, water depth, salinity and pH. Ten true species were found In the mangals of the coastal environment of Brgy. Caliling, Cauayan, Negros Occidental. They were Avicennia aiba, Avicennia Janata, Avicennia manna, Campostemon phiiHpinensis, Excoecaria agallocha, Osbomia octodonta, Nipa fruticans, Brugeria cylindrica, Rhizophora apiculata and R. mucronata. Standard Basal Area was highest in Station 3 with 7.54 m/ha. In terms of zonation, the landward zone was found to have the highest Stand Basal Area with 11.15 m/ha. Station 2 had the highest density value of 33.92 %, whereas in terms of zonation, both the middle and seaward zone had the density value of 36.20 %. Avicennia marina was found to be the most dominant species and was observed to occupy sites with hypersaline conditions, in silty clay to muddy substratum, which may or may not be inundated by tidal flow most of the time.

    Batog kag Aya-ay: The politics of ecological consciousness of the presidents of Barangay Pantalan President Roxas, Capiz
    Bañez, Ma. Arve (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1992-03-01)
    This study examines the folk consciousness on the environment of the residents of Barangay Pantalan, President Roxas, Capiz. A combination of the etic and emic approaches in social sciences was used to make sense out of the informations gathered from the field. This study also identifies Man as Master of Nature, Man and Nature in Antagonism, Man in Harmony with Nature, and Nature as Sacred as the different relationships between human being and Nature. These different relationships between human being and Nature are contained- in the two broad opposing rationalities, namely, Speciesism and Environmentalism. An ethnocartography of Barangay Pantalan is constituted in this study using the folk sense of direction and orientation. In addition, the study examines the folk beliefs and practices built around man-made structure, sea, and the flora and the fauna. This study concludes with a discussion of the politics of environmentalism. Human being does not dominate Nature nor Nature dominates human being in this politics of environmentalism. The same politics embodies ethical dimensions which check the drift toward the destruction of the environment.
