Biogeography is the study of the geographical distribution of flora and fauna across the earth’s landscapes. Biogeography is actually a subset of biology, however physical geographers have made many contributions to the discipline making it a part of Geography as well. The study of biogeography divides the earth’s surface into regions called biomes based on the composition of flora and fauna as a result of current and historical causes. These causes are brought about through evolutionary processes that gave birth to different species and genus, past and current climates and geographic characteristics that would have impacted the movement of flora and fauna (The Editors of Encyclopædia Britannica, 2016). These factors generated distinct differences …show more content…
Evidence of early biogeography can be found in written records from Aristotle (384-322 BC) with his question of “How are organisms distributed around the world?” (Welcome to Biogeography. (n.d.). While many were unknowingly using or thinking about biogeography, world exploration didn’t begin until the 1700s, starting with Carl Linnaeus, James Cook, Comte de Buffon, and Johann R. Forester with the collection of specimens that were cataloged and later compared to each other. James Cook led three of these world explorations during the years 1768-1771, 1772-1775, 1776-1779. Unfortunately, Cook did not make it back from his last voyage exploring a possible north channel to go around North America for he was killed on the Hawaiian Islands. Cook’s excellent mapping skills would enable more explorations of the world for years to come (MEDIA FACTORY Czech Republic, a. s. …show more content…
Sclater created one of the very first publications of biogeographic regions in 1858 based on the distribution of bird species. In the 1870s, Adolf Engler created a schema based on plant species while Sir Joseph Dalton Hooker’s collection of plant species and Alfred Russel Wallace’s zoogeographic work influenced Charles Darwin and led to the Darwinian Theory of Evolution (Groves, 2017). From the 1850s to 1900, the exploration of Natural Selection was of major interests, with the 1900s to 1950’s uncovering evolution and continental drift followed by ecological classifications and centers of origin being created. (Historical Development of Biogeography. (n.d.). Recently, works focusing on classifying biomes and analyzing changing migration patterns and species distributions of certain animals have been of major interests. These topics are most likely of major interest today due to changing climates and weather patterns that are influencing many of the factors that biogeography is focused
What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.

Palaeogeography deals with the reconstruction of physical geographical conditions for the eras of the Earth's history. The term comes from the Greek παλαιός (palaiós) meaning ‘old’ and γεωγραφία (geōgraphía) meaning ‘a description of the earth’ and seems to have been introduced in the Earth sciences vocabulary as ‘Palaeo-Geographie’ by Ami Boué (1794‒1881), a French‒Austrian geologist, in his publication Einiges zur palaeo-geologischen Geographie (Boué, 1875, p. 2). Palaeogeography focuses on the distribution of land and sea, the spread of mountains and volcanoes and the expansion of glaciations, among others. The results are presented in geographic depictions called palaeogeographic maps. A special kind of palaeogeograpahical map is palaeobiogeographical maps depicting the distribution of
Biodiversity is influenced by landscape fragmentation at various scales of space and time. The extinction of ecosystem types and component species may cause an increased patchiness of the landscape, resulting in lower population sizes and decreased connectivity. As a result, inhabitants may experience decreased dispersal abilities and lowered gene flows between populations.
“For whatever reason, there has been a continued pattern of misinterpreting or incorrectly describing multiregional evolution.” (Wolpoff et al. 2000)
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.
Marketing is a system of business activates designed to plan, price, promote and distribute want-satisfying products, services and ideas to customers in order to achieve business objectives. Consumer law protects consumer’s rights in the marketplace as well as fair trading, competition and accurate information. On the other hand, ethical aspects of marketing are about making marketing decisions that are morally right. However, consumer law and ethical aspects of marketing have a lot of advantages and disadvantages in the marketplace, which impacts business 's sales and growth like it happened to: Harvey Norman, Nurofen, apple, etc.
Susan Lindee and Ricardo Santos’ goal was to understand the contexts of genesis and development of biological anthropology around the world from an international standpoint, focusing on engagement with living human populations. Their contributors, scholars in history of science, science studies, and anthropology, were guided by key questions about national histories, collections, and scientific field practice.
When people think of geology, they usually think of rocks and fossils. However, geology is actually a very large field of study. The knowledge of geologists ranges from rocks and fossils to the moon and other planets (Hammonds 7-8). Geologists use a variety of subjects in their work, but the sciences and math are the most important. Some of the sciences geologists study are physics and chemistry (12). English is also a subject that geologists use when communicating with other scientists, the media, and the public (12) . Because of these tasks, it is important for geologists to have a wide knowledge of these different subjects.

NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution, invasive exotic species, diseases, shifting cultivation, poaching of wildlife etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its forms and should prevent the degradation as well as the destruction of the habitats, thereby maintaining the biodiversity at its optimum level which will ultimately conserve the biodiversity for the future generation. The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity. In biodiversity, each species, no matter how big or small, has an important role to play in ecosystems.
One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...
