The Wallace line or Wallace's line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by the English biologist T.H. Huxley. It separates the biogeographical realms of Asia and ' Wallacea ', a transitional zone between Asia and Australia formerly also called the Malay Archipelago and the Indo ...
Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species. [ 1 ] As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, morphology, phylogenetics , and Geographic Information Systems (GIS) to delineate evolutionary ...
After turning his attention to biology and completing eight years of work on barnacles, Darwin intensified work on his theory of species in 1854. Alfred Russel Wallace, a naturalist working in Borneo, had a paper on the "introduction" of species published in Annals and Magazine of Natural History. This made guarded comments about evolution, and ...
Alfred Russel Wallace (8 January 1823 – 7 November 1913) was an English [1] [2] [3] naturalist, explorer, geographer, anthropologist, biologist and illustrator. [4] He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic.
Biogeography now incorporates many different fields including but not limited to physical geography, geology, botany and plant biology, zoology, general biology, and modelling. A biogeographer's main focus is on how the environment and humans affect the distribution of species as well as other manifestations of Life such as species or genetic ...
The occurrence of the interchange was first discussed in 1876 by the "father of biogeography", Alfred Russel Wallace. [ 3 ] [ 4 ] Wallace had spent five years exploring and collecting specimens in the Amazon basin .
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Wegener felt personally responsible for the expedition's success, as the German government had contributed $120,000 ($1.5 million in 2007 dollars). Success depended on enough provisions being transferred from West camp to Eismitte ("mid-ice", also known as Central Station) for two men to winter there, and this was a factor in the decision that ...
