The Abert and the Kaibab species of squirrels live on opposite ends of the Grand Canyon. Physically they are very similar to each other, which leads scientist to think that when the Grand Canyon was shallower (millions of years ago) the populations use to have genetic contact (sexual reproduction). In present day, they are completely isolated from each other. When tested the Abert and Kaibab squirrels cannot produce a fertile offspring. This is an example of ___ speciation. [Fill in the blank]
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.
