Limiting factors study guide:
... When a bird eats a worm, the bird is the predator
After one species disappears, the other species in the ecosystem are thrown out of
Limiting factors determine an area’s carrying capacity because animals need
resources to survive
Competition is when two members of the same species fight over ...

Introduction to Biomes
... The Rule of Climatic Similarity
• Similar environments lead to the evolution of organisms
similar in form and function and to similar ecosystems
• This rule leads to the concept of the biome
• Biomes are the major regional groupings of plants and
animals discernible at a global scale.
Two groups of animals are defined as different species, when
... Two groups of animals are defined as different species, when individuals from one group don't
mate and reproduce with those from the other. One way for one species to split into two is for
populations to separate geographically. Over many generations they can undergo enough
changes in their respe ...
... When they compete, these niches overlap
The more they overlap the more they compete
Humans are competing with species for food, space
and other resources

exploitation competition. Summarize the competitive exclusion principle. List two strategies

and killing prey
• Can you name 3 of each?
• Prey also have many adaptations to avoid

The storage effect is a coexistence mechanism proposed in the ecological theory of species coexistence, which tries to explain how such a wide variety of similar species are able to coexist within the same ecological community or guild. The storage effect was originally proposed in the 1980s to explain coexistence in diverse communities of coral reef fish, however it has since been generalized to cover a variety of ecological communities. The theory proposes one way for multiple species to coexist: in a changing environment, no species can be the best under all conditions. Instead, each species must have a unique response to varying environmental conditions, and a way of buffering against the effects of bad years. The storage effect gets its name because each population ""stores"" the gains in good years or microhabitats (patches) to help it survive population losses in bad years or patches. One strength of this theory is that, unlike most coexistence mechanisms, the storage effect can be measured and quantified, with units of per-capita growth rate (offspring per adult per generation).The storage effect can be caused by both temporal and spatial variation. The temporal storage effect (often referred to as simply ""the storage effect"") occurs when species benefit from changes in year-to-year environmental patterns, while the spatial storage effect occurs when species benefit from variation in microhabitats across a landscape.
