One example of a population migrating in response to environmental stress is the Arctic caribou, which often move to new grazing areas when their traditional habitats are affected by climate change. Melting ice and changing vegetation patterns can lead to food shortages, prompting these animals to seek out more favorable conditions. This migration can also be influenced by increased predation or human encroachment on their habitat. Such movements highlight the adaptability of species in response to shifting environmental pressures.
The population could be reduced where the migrants are moving from.
Yes, geese migrating south for the winter is an example of innate behavior. It is an instinctual response that does not require prior learning and is genetically programmed in geese to ensure their survival and well-being during the colder months.
A population size decrease is the usual response in the population size of many species to a density-independent limiting factor. Not enough food is an example of a limiting factor.

The darkening of the population of the peppered moth in Europe over a relatively short time demonstrated natural selection in action. The change in moth coloration was a response to industrial pollution, where darker moths had a survival advantage in a polluted environment as they were better camouflaged from predators. This phenomenon provided a clear example of adaptation and evolution in response to changing environmental conditions.
One example of a migrating rodent is the lemming. Lemmings are small rodents that live in the Arctic regions and are known for their cyclic population fluctuations and long-distance migrations in search of food and suitable habitats. During these migrations, lemmings may travel long distances, sometimes facing obstacles such as rivers or other natural barriers.
An example population for a maple tree could be a specific area in a forest where a group of sugar maples (Acer saccharum) is growing. This population would consist of all the individual sugar maple trees in that designated location, sharing similar environmental conditions and genetic traits. The population dynamics can be studied to understand growth patterns, reproductive success, and responses to environmental changes within that specific habitat.
a reflex ia an example of an instinctive response
A behavioral response to environmental variability or stimuli for example, is the change of seasons, global warming or an ice age. In the change of an animal's environment, such as season change; many migratory birds "fly south for the winter." And the Monarch Butterfly fly from Northern U.S.A. to South America. So the answer would be, "migrating to a different environment" Even during a global cooling or warming, this influences animals to migrate or die. Plants can't migrate and have to depend on the digestion of a bird or animal to redeposit its seeds elsewhere.
An example of the modification of a phenotype by an environmental factor is the coloration of the Arctic hare. During summer, the hare has a brown coat to blend in with the environment, while in winter, it changes to white to camouflage against the snow. This change in fur color is not due to genetic alteration but is a phenotypic response to seasonal environmental conditions. Thus, the hare's phenotype is directly influenced by its surroundings.
