combinations of N1 and N2 for which the growth rate = 0 for each species-population
an equilibrium point at which, if either population changes, the population sizes will diverge from, rather than return to, the equilibrium point; a combination of population sizes at which the two populations could coexist, but when the combination changed, no impetus exists to return to the equilibrium population sizes.
the combination of population sizes that will ultimately result regardless of the initial combination of population sizes.
by graphing the equilibrium population sizes obtained form the Lotka-Volterra Model.
the combination of population sizes that will ultimately result regardless of the initial combination of population sizes.
This ecosystem is exhibiting stability or equilibrium. This stability suggests a balanced network of interactions among species, where populations remain relatively constant over time. Any disturbance may disrupt this equilibrium, leading to changes in population sizes or community structure.
In a non-equilibrium population, the number of generations needed for random mating to reach equilibrium depends on various factors such as population size, selection pressure, genetic diversity, and mutation rate. It can range from a few generations to many generations, and sometimes equilibrium may not be reached due to ongoing evolutionary forces.
A large population residing on an isolated island is more likely to reach Hardy-Weinberg equilibrium.
The genetic equilibrium of a population can be disturbed by mutation, gene flow, genetic drift, and natural selection.
Migration can introduce new genes into a population and increase genetic diversity, thus potentially disrupting the genetic equilibrium. If individuals from a different population arrive and interbreed with the local population, they can alter allele frequencies and introduce new variations. Over time, this can impact the gene pool and change the genetic equilibrium of the population.
It is true.
Some examples of equilibrium species include stable populations of certain animals in their habitats, such as deer in a forest or fish in a lake. In ecology, equilibrium species refer to those that are well adapted to their environment and have stable population sizes over time, without experiencing rapid growth or decline. These species play a key role in maintaining the balance of ecosystems.
When a population is not evolving, it is called being in genetic equilibrium. This means that the frequency of alleles in the population remains constant from generation to generation. Evolution requires changes in allele frequencies, so genetic equilibrium indicates no evolution is occurring.
