High-altitude plants must adapt to the harsh conditions of their environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season. Trees cannot grow at high altitude, because of cold temperature or lack of available moisture.
Adaptation is an observable fact of life accepted by philosophers and natural historians from ancient times, independently of their views on evolution, but their explanations differed. Empedocles did not believe that adaptation required a final cause (a purpose), but thought that it "came about naturally, since such things survived."
Organisms can adjust their morphological, behavioral, physical, and/or biochemical traits in response to changes in their environment. [1] While the capacity to acclimate to novel environments has been well documented in thousands of species, researchers still know very little about how and why organisms acclimate the way that they do.
As you can see, our resident animals adapt and change for the winter season. Therefore, they fit Meggison’s and Darwin’s rules/statements and we can expect many of them to successfully survive ...
But the actual effect of climatic adaptation depends greatly on the species in question and often the amount of genetic variability within that species. The bodies of some animals, such as woodrats, are inversely correlated with the mean annual temperature of their environment. [9] This is an applied example of Bergmann's rule
This role, commonly known as an ecological niche, is simply how an organism lives in an environment in relation to others. [3] Over successive generations, the organism must adapt to their surrounding conditions in order to develop their niche. An organism's niche will evolve as changes in the external environment occur.
Temporal plasticity, also known as fine-grained environmental adaptation, [63] is a type of phenotypic plasticity that involves the phenotypic change of organisms in response to changes in the environment over time. Animals can respond to short-term environmental changes with physiological (reversible) and behavioral changes; plants, which are ...
Local adaptation is a mechanism in evolutionary biology whereby a population of organisms evolves to be more well-suited to its local environment than other members of the same species that live elsewhere. Local adaptation requires that different populations of the same species experience different natural selection. For example, if a species ...
