1) protect species richness to maintain ecosystem functional diversity and enhance ecosystem function and stability 2) protect keystone species, which have greatest effects on overall ecosystem function 3) protect species with unique (specialized) functions, not easily replaced by other species Biodiversity is the variety and variability of life on Earth.Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Ecosystem diversity is very important because all life forms on earth depend on each other. STUDY. 1) species geographic distributions, based on pollen records from lake sediments during Quaternary Period, moved independently of each other. How will global warming drive geographic migrations? Both birds and bats significantly reduced arthropod herbivores and thus herbivory compared to controls. 1) harder to acknowledge intrinsic value of ecosystems if they're transient (in time and space), haphazard assemblages of species. ecosystems are a haphazard, loosely structured assemblage of species, temporarily sharing a region. What are two pieces of evidence that support the idea that species richness does increase ecosystem stability? Bats consume insects that would otherwise eat/destroy crops. PLAY. The Flannelmouth Characin preforms the function bioturbation, which is stirring up the sea floor. High diversity among types of ecosystems … What are 5 possible environmental features that could affect the positive relationship between biodiversity and ecosystem multifunctionality? The name of an ecosystem doesn't automatically imply that all the species in that ecosystem are the same everywhere in the world. The Nature Conservancy- they recognize 6-ecoregions in Louisiana, group of ecosystems with greatest plant similarity index. The variety of forests, deserts, grasslands, oceans, streams,…. There is less biodiversity in the ecosystem. 1) more species=more complex food webs, redundancy and more complimentarity of ecological function, if one species is hurt by a selective pressure there may be another species present that has a similar role and is able to take over that role so nothing in the environment slips, Are species within an ecosystem functionally redundant? It is sometimes confused with ecological diversity which is the number of species within a community. Why is the boundary of the Greater Yellowstone ecosystem not only national parks but also national forests? b. This implied that birds, and especially bats, help plants grow by controlling plants' enemies (herbivores that eat plants and therefore reduce growth). Variety of processes that occur within ecosystems, such as energy flow and matter cycling. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Biodiversity is not distributed evenly on Earth, and is richer in the tropics. breeding grounds for redfish, shrimp and oysters, tropical marine wetlands comprised of woody, salt-tolerant plants that cannot tolerate freezing. 1) a single species can influence ecosystem function. You can have similar-looking ecosystems that have very different makeups. Other animals benefit from the presence of Flannelmouth Characin because they get nutrients from the bioturbation and recycling preformed by Characin. What is one threatened species associated with the lower east gulf coastal plain? Who is a leader in the bioregionalism movement and why? The number and relative abundance of species in a biological c…. It is not the diversity of species within an ecosystem. An ecosystem with one species is likely to split into multiple species. ecosystem preservation as surrogate for species conservation, the idea is to save species and other forms of biodiversity by saving examples of all ecosystems; using ecosystems as a surrogate for the rest of biodiversity, focuses on a particular species that needs individual protection, benefits ecosystems provide to humans; utilitarian (or human) centered value. How can an ecosystem have economic value (4)? 1) economic value 2) spiritual value 3) scientific/educational value. the entire earth functions like an organism; each species is like an organ or a tissue; the earth tends to regulate the concentrations of gases/water/etc. Define functional biodiversity.
