Eugenius Warming's work with ecological plant geography led to the founding of ecology as a discipline. [6] Charles Darwin's work also contributed to the science of ecology, and Darwin is often attributed with progressing the discipline more than anyone else in its young history. Ecological thought expanded even more in the early 20th century. [7]
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.
Controversy exists as to whether Charles Darwin recognized a true geographical-based model of speciation in his publication On the Origin of Species. [5] In chapter 11, "Geographical Distribution", Darwin discusses geographic barriers to migration, stating for example that "barriers of any kind, or obstacles to free migration, are related in a close and important manner to the differences ...
Speciation is the evolutionary process by which populations evolve to become distinct species.The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.
George Evelyn Hutchinson ForMemRS (January 30, 1903 – May 17, 1991) was a British ecologist sometimes described as the "father of modern ecology." [2] He contributed for more than sixty years to the fields of limnology, systems ecology, radiation ecology, entomology, genetics, biogeochemistry, a mathematical theory of population growth, art history, philosophy, religion, and anthropology.

species differences may be caused by geographic isolation; the species may or may not occupy different habitats if they existed in sympatry; in cases of similar habitats in allopatry, species may be adapted to unknown ecological factors; if the species existed in sympatry, competition may drive habitat segregation that would be undetectable in ...
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1]
Humboldt described many geographical features and species that were hitherto unknown to Europeans. Species named after him include: Spheniscus humboldti – Humboldt penguin; Dosidicus gigas – Humboldt squid; Lilium humboldtii – Humboldt's lily; Phragmipedium humboldtii – an orchid; Quercus humboldtii – South American (Andean) oak
