Without invoking ecological differences among individuals of different species, and assuming that ecological interactions emerge randomly, we demonstrate that a spatially explicit multitrophic neutral model is able to capture the recurrent structural patterns of mutualistic networks (i.e., degree distribution, connectance, nestedness, and phylogenetic signal of species interactions). Nonrandom species distribution, caused by probabilistic events of migration and speciation, create nonrandom

_________ habitat specialist found exclusively in one specific type of habitat. A) keystone species B) endemic species C) pioneer species D) niche species E) mutualistic species. Individual species will continually evolve as a result of: A) Coevolution. These keystone species are often top predators such as sharks, because of the role they play in controlling prey. The southern cassowary, however, is also a keystone species as it spreads the seeds of as many as 238 plants across northern Queensland. Species Interactions.

More species are becoming extinct today than at any time since dinosaurs were wiped off the face of the Earth by an asteroid 65 million years ago. Yet this bio-Armageddon, caused mainly by humans, is greeted by most of us with a yawn and a shrug.

Evolution, Biological Communities and Species Interactions 4.1 Describe how evolution produces species diversity. 4.2 Discuss how species interactions shape biological communities. 4.3 Summarize how community properties affect species and populations.

Communities. All species living in a specified geographic region or all species that potentially interact with one another in a given region. Ecosystems. Communities of living things and their nonliving environment. Small as a field. Large as a half continent. Have varied characteristics. Variation. Change over time, evolve. Evolution

Communities. All species living in a specified geographic region or all species that potentially interact with one another in a given region.

Example: A lava flow creates a new land area that is colonized. The first colonists are termed pioneer species. - a community begins to develop on an unoccupied site - occur after disturbances have been harsh enough to wipe out previous species - role: give nutrients in the soil ex: A lava flow creates a new land area that Is colonized. - - the first colonists are termed PIONEER SPECIES Species evolve when two groups of one species get separated.

How do species interact to create the fundamental properties of biological communities and ecosystems? 1) diversity and abundance 2) community structure and patchiness 3) complexity, resilience, productivity, and stability

Evolution by one species to resemble another species that is protected from predators by a venomous stinger, bad taste, or some other defensive adaption.
