A field ecology study on an enclosed compound
located in Bacong, Negros Oriental
The world is in a constant change, and with it, every living being adapts to these changes. Ecology plays a major role in how the world and its inhabitants work. Before we start, to have a deeper understanding, let us define ecology. So what is ecology? In University of Western Cape’s introduction of their botany course, they defined ecology. In their introduction, it was stated that ecology is the scientific study of interactions of organisms with one another and with the physical and chemical environment. Although it includes the study of environmental problems such as pollution, the science of ecology mainly involves research on the natural world from many viewpoints, using many techniques. Modern ecology relies heavily on experiments, both in laboratory and in field settings. These techniques have proved useful in testing ecological theories and in arriving at practical decisions concerning the management of natural resources (University of Western Cape, 2006).
Furthermore, they stated that an understanding of ecology is essential for the survival of the human species. Our populations are increasing rapidly, all around the world, and we are in grave danger of outstripping the earth’s ability to supply the resources that we need for our longterm survival. Furthermore, social, economic, and political factors often influence the short-term distribution of resources needed by a specific human population. An understanding of ecological principles can help us understand the global and regional consequences of competition among humans for the scarce natural resources that support us.
Ecology is a science that contributes considerably to our understanding of evolution, including our own evolution as a species. All evolutionary change takes place in response to ecological interactions that operate on the population, community, ecosystem, biome and biosphere levels. Studies conducted within the scientific discipline of ecology may therefore focus on one or more different levels: on populations of a single species, on an interacting
community involving populations of many species, on the movement of matter and energy through a community within and ecosystem, on large-scale processes within a biome, or on global patterns within the biosphere.
At the end of the field exercise, we should be able to conduct a survey of the area, identify the characteristics of the community, and estimate the density of common organisms in the community surveyed. We are only limiting our study to the aforementioned scope.
3. MATERIALS AND METHODS
3.1. The Site
In this experiment, we are to select a site of our choosing, be it terrestrial, aquatic, and so on. The group has decided that the site we choose be terrestrial. The site is located in Combado, Bacong, Negros Oriental. It is around 12 km away from Silliman University and will take around 15 min to get there (Figure 1). It has a total area of 3640 m2 (Figure 2). The site is an enclosed compound owned by Arch’t. Felix Villahermosa. The site was originally used as storage site for all construction equipment. This is clearly shown, for example, by the piles of concrete hollow blocks and roofing materials as shown in Figure 3. Because of the large vacant part of the lot, the owner decided to plant assorted plants and trees, such as coconuts, bananas, and pineapple. In addition, the owner also decided to raise some poultry animals. He has a caretaker to do all the aforementioned.
3.2. Layout and Survey
Before we started laying out the transects, we have gathered the following materials for the field activity:
10-m measuring tape
2 rolls plastic string (50 m each roll)
4 wooden sticks
To begin with, the wooden sticks were sharpened...
