Biogeography is the study of the patterns of geographic distribution of organisms and the factors that determine those patterns.
1. The definition of biogeography is the study of the places where animals and plants are distributed. An example of biogeography is classifying the floral region of South American as Neotropical, and the floral region of North American as Boreal. noun.
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
Biogeography is important as a branch of geography that sheds light on the natural habitats around the world. It is also essential in understanding why species are in their present locations and in developing protecting the world's natural habitats.
Biogeography is the study of the geographical distribution of living and fossil plants and animals as a result of ecological and evolutionary processes. Biogeography analyzes organism-environment relations through change over space and time, and often includes human-biota interactions.
biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.
Being a multidisciplinary science, Biogeography has grown into a bigger field. It is divided into many branches like: a) Historical biogeography b) Phylogeography c) Zoogeography d) Island Biogeography e) Palaeobiogeography f) Ecological biogeography g) Conservation biogeography.
Biogeography is the geography of organic life, the study of the spatial distribution of animate nature, including both plants and animals and the processes that produce variations in the patterns of distribution.
Traditionally, biogeography has been divided into two different approaches (Morrone and Crisci 1995): ecological biogeography, the study of the environmental factors shaping the distribution of individual organisms at local spatial scale, and historical biogeography, which aims to explain the geographic distribution of ...
Alfred Russel Wallace
Much of this knowledge has emerged from the tremendous body of work from one scientist, Alfred Russel Wallace (Figure 1), widely regarded as the “Father of Biogeography.” Aside from co-originating the process of Natural Selection with Charles Darwin, Wallace spent extended periods studying the distribution and ...
Alfred Russel Wallace studied the distribution of flora and fauna in the Amazon Basin and the Malay Archipelago in the mid-19th century. His research was essential to the further development of biogeography, and he was later nicknamed the "father of Biogeography".
Buffon's observations led to the first principle of biogeography, known as Buffon's Law. It states that environmentally similar but isolated regions have distinct assemblages of mammals and birds. ... Developed one of the first systematic descriptions of the world's biotic regions.
Historical biogeography is the study of animal distributions emphasiszing evolution and over evolutionary time scales, and using a combination of phylogenetic and distributional information.
' To answer this question, Wallace proposed the Sarawak Law: 'Every species has come into existence coincident both in space and time with a pre-existing closely allied species. ' In other words, new species evolve from existing ones, rather than simply appearing where they are.
Wallace fell in love with Sarawak and realized that it was a perfect collecting ground, mostly for insects, but also for the much sought after orangutans. He stayed in the area a total of 14 months, his longest stay anywhere in the archipelago.
The Wallace Line is an imaginary boundary that runs between Australia and the Asian islands and the mainland. This boundary marks the point where there is a difference in species on either side of the line.
Australia's rocks are much older than those of New Zealand. Australia's highest mountains are the Great Dividing Range, while New Zealand has a spine of much higher mountains. New Zealand has a moderate, moist climate, whereas Australia's climates vary from tropical to Mediterranean to desert.
When the Central American land bridge began to form, marsupials began to spread south, and only just in time, because the asteroid impact that wiped out the dinosaurs seems to have all but killed off the North American marsupials as well.
