Ecological, chromosomal, and molecular divergence, therefore, may reflect a wider pattern of lineage splitting within the molecular forms of An. gambiae across West and Central Africa that is occurring along major ecological breaks [ 18].
When such ecological barriers break down for animals--for example, when two species of Darwin's finches colonize the same Galápagos island--hybridization can occur, blurring the lines between species.
Similar changes might occur for species pairs with allotopic distribution patterns, e.g. if ecological barriers break down due to habitat deterioration or alteration [ 24, 29, 30].
Yeasts, which are single-celled fungi, are everywhere in nature and can perform many ecological functions, like breaking down dead plant tissue and encouraging root growth.
The activities of these beetles are linked to a wide variety of ecological processes including breaking down and moving excrement, the incorporation of organic matter into the soil, bioturbation (i.e., moving and mixing soil particles), controlling the parasites and flies that affect livestock, pets and people, and secondary seed dispersal, see [18] and references cited therein.
No, but when I was in college I did read 'Ecotopia' "—Ernest Callenbach's novel about the Pacific Northwest breaking off into a rogue ecological state—"and I want to go back and read it now".
We need a radically different model of regulated trade and controlled investment if we are to have any chance of breaking the cycle of economic and ecological crisis.
The museum will focus on science, and on the sustainable and ecological future of 2061, 50 years from the museum's 2011 ground breaking.
It is assumed that the chain of the above listed events from cultivation to ecological harm is obviously broken at one or more links [7].
From the ecological prospective, the singularity-induced bifurcation will lead to a surge in a population density within a short period of time and eventually break the ecological balance.
