Blog post 6: Data collection

The study employed observation and sampling technique in the data collection process. The field activities included in data collection included identification of the study locations whereby observation and historical reports were employed in the decision on the suitable locations. The random sampling method was used to select the 4 study areas out of the total 29 locations. Each study area was marked into a 0-1ha space by use of strings and sticks. Then 7 quadrats were developed for each study area with each quadrant being 1 square meter in size. The quadrats were randomly placed in each study area. Then the key field activity of observing, classifying, and recording the number of target species in each quadrat was conducted. The recorded data was then transferred to the computer for the analysis process. Additionally, the light intensity, temperature, and soil pH aspects in each study area were recorded by light meters, thermometers, and pH meters respectively to enable effective comparison process as well as the hypothesis testing process.

The study selected five replicates that were sampled in each quadrat and study area for all study locations. The five selected replicates consisted of two animal species and three plant species. The sampled replicates included grass, mammal, insects, tree, and moss species. The selection of the replicates was enhanced by the hypothesis and the major goal of the study in determining the effects of climate change on biodiversity and reproduction factors in mountain regions.

The overall population results had a particular pattern depending on the altitude, the temperature, and the light intensity of the particular location. Fewer species for both the animal and plant replicates were found in areas near the mountain tops (Malhi et al 169-172). The pattern of decreasing plant and animal species in the regions was a clear indication of the negative effects of global warming and global climate change to the biodiversity in the mountain regions as stated in the hypothesis.
