Discuss how the distribution of a species can be affected both by its evolutionary history and by ecological factors. Could ongoing evolutionary change also affect its distribution? Explain.

Short Answer

Expert verified

The combination of both evolutionary history (change in species characteristics over a generation) and ecological factors affects where species inhabit. Species are restricted to the single continent where their ancestors originated.

Step by step solution

01

Species

Species is the classification of a large group of biological organisms like plants or animals with shared characteristics with members interbreeding among themselves.Examples of different species includeblack bears, sunflowers, humans, microscopic bacteria, jack pines, white-tailed deer, and moose.

Various characteristics related to species are shared gene pool, similar biochemistry, similar anatomy, interbreeding, and similar genetic material.The different roles performed by species in an ecosystem are species diversity, influence productivity, ecological niche, and ecosystem’s integral component.

02

Biogeography

Biogeography is the subfield of geographic and biological disciplines that focus on past and present species and ecosystem distribution in the geographic space.

Biogeography branches include ecological, island, palaeobiogeography, and conservation biogeographies.An example of biogeography is the classification of the floral region of North and South America.

03

Evolutionary history and ecological factors 

Ecological factors(factors influencing living organisms like light, soil, and temperature)such as biotic and abiotic factors limit species distribution. When species are distributed to a new area, they are unable to survive and reproduce due to the incompletion of their life cycle.

Predation, competition, and parasitism are considered negative interactions of species with other organisms, which cause relocated species to be unable to complete their life cycle. The evolutionary change also affects the distribution of species due to their adaptation in different environments.

WHAT IF? Changes in Earth's climate at the end of the last ice age happened gradually, taking centuries to thousands of years. If the current global warminghappens very quickly, as predicted, how may this rapid climate change affect the evolution of long-lived trees compared with that of annual plants, which have muchshorter generation times?

Give examples of human actions that could expand a species' distribution by changing its (a) dispersal or (b) biotic interactions.

If global warming increases average temperatures on earth by 4°C in this century, predict which biome is most likely to replace tundra in some locations as a result. Explain your answer.

Jens Clausen and colleagues, at the Carnegie Institution of Washington, studied how the size of yarrow plants (Achillea lanulosa) growing on the slopes of the Sierra Nevada varied with elevation. They found that plants from low elevations were generally taller than plants from high elevations, as shown in the diagram. Clausen and colleagues proposed two hypotheses to explain this variation within a species: (1) There are genetic differences between populations of plants found at different elevations. (2) The species has developmental flexibility and can assume tall or short growth forms, depending on local abiotic factors. If you had seeds from yarrow plants found at low and high elevations, how would you test these hypotheses?
