New University of Colorado Boulder - led research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines.

Competition between nonautochtonous (in this case pathogenic) and autochtonous bacterial populations (typical soil microorganisms) as they pass through a planted soil filter diminishes the survivability of pathogenic bacteria.

The geologic record shows that the differences in ice cover, sea level and precipitation as well as in plant and animal populations were quite dramatic between the ice ages and the warm interglacials.

Understanding the molecular basis of interactions between plants and nematodes could lead to the development of new strategies to control these major agricultural pests and help feed a growing global population.

«We resequenced the genome of each individual that we collected and looked at which genes were differentiated between populations adapted to different host plants,» Nosil said.

As it turns out, despite the initial skepticism about the importance of gene flow, modern empirical and theoretical research using up - to - date molecular and DNA techniques have shown us not only how surprisingly far the flow of genes between distant plant populations can be, but also that the flow of alleles among populations is just as important, if not more so in some cases, as natural selection.

An implicit assumption in the discipline of speciation biology is that genetic differences between populations of animals and plants in a given species are important drivers of new species formation and are a key to understanding evolution.

When the earth's temperature rises on average by more than two degrees, interactions between different consequences of global warming (reduction in the area of arable land, unexpected crop failures, extinction of diverse plant and animal species) combined with increasing populations mean that hundreds of millions of people may die from starvation or disease in future famines.

As pockets of forest habitat are isolated, their edges are exposed to harsher, brighter, drier conditions and plant and animal dispersal between habitat fragments is made more difficult; in addition, habitat fragments may be too small to sustain populations of some species.

We saw virtually no differences between the biology of insect populations reared on the GM cotton and the non-GM cotton... We have indeed seen a dramatic boost to India's cotton, but we had always anticipated that at some point in time, we'll encounter pests that can withstand the modified plants.
