What is an ecological barrier?
biotic barriers to dispersal/establishment (ex. competition, pollination vectors)
True or false an existing community is gradually replaced by another community in an ecological succession?
Ecological Succession--The gradual replacement of one community by anotherPrimary Succession--Ecological succession that happens where there are few, if any, living things.Secondary Succession--Ecological succession in a place where a community already exists.
In Rosemary and Peter Grant's study of the Galapsgos finches what process was encouraged by ecological competition during the dry season?
Directional selection
How does a competitive exclusion differs from ecological equivalents?
Gausse's competitive exclusion principle says that "no two organisms can have same niche but provided that competition must be there between two organisms".but if the two organisms sre separated by time or by space no competition would be there between them.In case of ecological equivalents the two species are separated by space(they have different habitat).
When do enzyme competition occurs?
For competition to occur, the environment somehow must be limiting (i.e., there must be something to compete for)
What is an ecological barrier?
biotic barriers to dispersal/establishment (ex. competition, pollination vectors)
What is the status of Philippine florafauna and ecological equilibrium?
What is the status of the Philippines Flora, Fauna and Ecological Equilibrium
What are the clements six phases climax?
The Clements six phases model describes the sequence of ecological succession as: 1) bare substrate, 2) colonization, 3) establishment, 4) competition, 5) climax, and 6) retrogression. The climax phase represents the stable endpoint of succession where the ecosystem reaches a state of equilibrium and species composition remains relatively constant.
What are the two kinds of ecological relationship?
competition and predation
How can ecological competition be modeled?
Competition also can be modeled by examining resources rather than population growth equations.
How are ecological Competition coefficients measure?
Competition coefficients measure the effect of one species on another competing species.
What behavioral factors affect the ecological balance?
haist inde ko alam gagawin ko !!
What has to happen for ecological competition to occur?
The environment somehow must be limiting.
What are the different of ecological relationship?
Predation,parasitism,mutualism,commensalism, and competition.
What is ecological modeling?
(a) The point where the isoclines intersect is a stable equilibrium (b) No matter what the initial combination of individuals, the interaction will ultimately lead to the combination at the stable equilibrium point
2 examples of flower ecological competition?
weeds would be one example.
What is Ecological Displacement?
it is spatial or temporal characteristics of organisms that have changed because of competition.
