Symbiosis of plants and fungi has a tremendous impact on the large distribution of plant shapes. In some cases, it also functions as a filter. This was found by an international group of explorers with the role of the göttingen Institute. The results are published in the journal Nature Ecology & Evolution.

In the colonization of the Islands of plant forms a significant role is played not only by these points, as the size of the island, isolation and geological formation, but also the interaction between the forms. Scientists have checked, in fact, that the symbiosis of plants and fungi—mycorrhiza—has a special meaning. 2 of the body to exchange hearty drugs through the delicate root system of the plant, the fungus receives carbohydrates from the plant; the plant receives high-calorie medications that the fungus has absorbed from the earth.

"For the first time, recent data on the large distribution of plant species in 1,100 island and mainland habitats enable us to study the impact of this interaction on a mass scale," says Dr. Patrick Weigelt of the biodiversity, macroeconomics and biogeography division of the göttingen Institute, which worked on the study. Results: mycorrhiza-the interaction of plants, which, of course, are seen less often on the Islands, due to the fact that both organisms rely on a friend friend, it means that the colonization of remote Islands is difficult. The inaccessibility of this symbiotic relationship has the ability to slow down the spread of plants. This is not the case with plant images introduced by humans, because fungi and plants are often introduced together. Head of the Department Dr. Holger Creft adds: "a fraction of the appearance of plants with mycorrhizal interactions still increases from the poles to the equator."One of the most visible biogeographic regularities, increasing the number of faces from the poles to the tropics, is tightly connected with this symbiosis.

Dr. Camille Delavo, the main Creator from the Institute of Kansas (USA), explains: "We show that actually a symbiotic Association of plants with mycorrhizal fungi is considered to be undervalued by the mass driver biogeographic patterns of plants. It contains significant results for our progressive awareness of island biogeography and human-induced invasions of plants."The results demonstrate the fact that a difficult relationship between different organisms are of crucial meaning for understanding models of mass contrast and storage of bio contrast. "The inaccessibility of the interaction partner has the opportunity not to observe ecosystems and make them more susceptible to biological invasions," weigelt emphasizes.
