Document Summary
Communities: groups of interacting species that occur together in the same space and time. Communities often defined at the local level and ultimately include all the living things in an area that interact. Sub-communities are usually defined by the researcher: e. g. a scientist/conservationist might be interested in climate change impacts on the (cid:862)(cid:373)igrator(cid:455) so(cid:374)g(cid:271)ird (cid:272)o(cid:373)(cid:373)u(cid:374)it(cid:455)(cid:863) (cid:449)ithi(cid:374) a (cid:272)ertai(cid:374) ha(cid:271)itat or park. Interaction web: includes relationships between and among members. Community structure: a set of characteristics that shape a community: species diversity, species composition (identity, physical structure (layers, size of vegetation, other physical components, hetero/homogenous habitat) Deserts: more simple, less layers structurally rainforest: lots of layers with complex ecosystems. Biodiversity: (less specific term referring to) the diversity of important ecological entities that span multiple spatial scales, from genes to species to communities to ecosystems: species diversities: number and abundance of species. Biodiversity (biotic/abiotic factors) from all types of trees to plants to small to large organisms.
