... on the evolutionary causes and consequences of ecological interactions (intra-specific, interspecific, and with the abiotic environment). Appropriate topics of investigation include the selective pressures imposed by abiotic ... and consequences of phenotypic plasticity; life-history evolution; the evolution of interspecific relations (predator-prey, competition, cooperation, mutualism, parasitism, ...

Artists' rendering of the methyl anthranilate molecule, responsible for "foxy" aroma in grapes and wine By Tom Mansell, Science Editor Interspecific grape hybrids (hereafter: hybrids) were initially bred in the late 19th century in response to phylloxera, an American grape pest that migrated across the ocean to Europe and began to decimate the less-resistant vinifera vines, ...

While I've heard reports of putative Corydoras hybrids, I have never seen any direct evidence of interspecific mating until this past week. My main tank has a variety of corys - Corydoras panda, C. punctatus, C. arcuatus, C. aeneus, a probable C. trilineatus and another species whose identity I don't know. While I started off with several C. trilineatus, I only have one left. And ...

... a heterogeneous distribution of FST values between autosomes and heterochromosomes. When we compared the FST values obtained in this study with another evolutionary measure obtained by comparative interspecific approach, we found that genes under positive selection appeared to show low levels of population differentiation. We applied a gene set approach, widely used for microarray data analysis, ...

... all of its offspring were to be infected at germination. Finally, because perennial adults are superior to annuals in competition for light and nutrients, loss of perennial biomass reduces interspecific competitive pressure on annuals. Thus, the disease is more detrimental to the long-lived perennial life history than to the annual grass life history; this permits annuals to increase in relative ...
