EVOLUTION CONNECTION The fossil record indicates that therehave been five mass extinction events in the past 500 millionyears (see Concept 25.4). Many ecologists think we are on theverge of entering a sixth mass extinction event. Briefly discussthe history of mass extinctions and the length of time it typicallytakes for species diversity to recover through the process ofevolution. Explain why this should motivate us to slow theloss of biodiversity today.
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.
