To understand the biodiversity of insects in different sites around their community, students performed a leaf litter lab where leaf litter was collected from two sites: one from beneath the trees in an organically managed, commercial landscape established one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed or managed in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaf litter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with a light shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled container below the funnel, and the species were identified using magnifying lenses and a key. (j) Explain how modifying the experiment to collect samples from wet and dry sites could alter the results of the experiment.
Biogeography
The study of plants, animals, and other living things in terms of their geographic distribution is referred to as biogeography. Biogeography is usually examined in coexistence with ecological and historical variables that have affected organisms' spatial distribution across time. It is not only based on the habitation patterns; it is also about the reasons that cause differences in distribution. Biogeographic studies divide the Earth's surface into diverse flora and fauna compositions, notably the continents and islands. Biogeography is a field of science, but physical geographers have made vital commitments, especially in flora. Biogeography is a multidisciplinary field of study that combines concepts and data from ecology, evolutionary biology, taxonomy, geology, physical geography, paleontology, and climatology.
Types of Climate
The weather pattern in a long-term process in a locality, region, or even over the entire globe is known as climate. Generally, it is decided by calculating an average of thirty years' weather in a region. In that sense, the weather and climate are different.
Biome
It is defined as a definite community of animals and plants residing together in a climate. Each (plants and animals) having a characteristic appearance and distributed over a wide geographical area defined largely by regional climatic conditions.
