1 Shaping Communities 5.3

2 Shaping Communities 5.3 Niche  a species way of life, or role/function the species plays in its environment… “occupation” How does “it” use the physical environment? How does “it” interact with other species? Others… Fundamental niche: range of conditions and resources a species can tolerate and potentially use (no influence of competition, predation, etc.)… very broad Realized niche: range of resources it actually uses (influenced by competition)… narrow, more specific generalists (organisms with broad niches) vs specialists (organisms with narrow niches) Ex. koala and opossum (which is which?)

3 Competition for resources  Winner/Loser: competitive exclusion (one species eliminating another through competition). Ex. invasive species vs. native species Coexisting: division of resources (aka “resource partitioning”); fundamental niche vs. realized niche. Ex. fig. 9 pg. 114

4 Ecosystem Resiliency (stability) predation, keystone species, & biodiversity Predation can reduce the effects of competition among species Ex. mussels (good competitors for space in ocean) --sea stars eat mussels --when sea stars are present, a variety of species are able to live in the same area that the mussels live (intertidal zone) Ex. sea otters (eat sea urchins) --sea urchins eat kelp --kelp forests provide habitat for many aquatic animals --predict what would happen if the sea otters were removed from the ecosystem

5 Keystone species: one that is critical to an ecosystem b/c it affects the survival and number of many other species in its community (ex. sea otters and sea stars from previous slide). Biodiversity…# of species w/i a community. higher biodiversity  increased resiliency (“healthy” ecosystem). predation helps increase biodiversity …explain how this is possible.
