| Description: Ecosystems vary greatly in size The term “ecosystem” is most often applied to self-contained systems of moderate geographic extent Adjacent ecosystems may share components and interact Ecotones = transitional zones between two ecosystems in which elements of different ecosystems mix Landscape = larger than an ecosystem and smaller than a biome Landscape ecology = study how landscape structure affects organisms Their abundance, distribution, and interaction Patches = form the landscape, and are distributed spatially in complex patterns (a mosaic) Metapopulation = a network of subpopulations Most members stay within patches May move among patches or mate with those of other patches Individuals in small patches risk extinction Conservation biology = study the loss, protection, and restoration of biodiversity Picture Stats: Views: 342 Filesize: 120.71kB Height: 929 Width: 701 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=35631 |
