What else can I help you with?
A population of animals is split in half by a river. Before speciation is completed the two halves are rejoined when a drought causes the river to run dry how would this impact the two populations?

Name three things that have changed parts of the sahel from marginal land into barren wasteland?
climate, increased population and continuous drought
Why is a drought a density independent limiting factor?
A drought is considered a density-independent limiting factor because it affects all individuals in a population regardless of their population density. It reduces the availability of water, impacting the survival and reproduction of organisms, leading to a decline in population size.
What are the positive effect of factors that can affect population distributin?
drought and unfavourable weather condition
Why is drought a density-independent limiting factor?
Drought is considered a density-independent limiting factor because its impact on a population is not directly related to the population size. Drought affects all individuals in an area regardless of their density, leading to decreased resources like water and food which can limit population growth or survival. This contrasts with density-dependent factors, which have a stronger impact on populations as they become more crowded.
If a drought causes the stream to run dry one year how will this likely impact the black bear population?
The population's size will decrease.
What effect would a severe drought have on the population of antelope?
