... to subtle signals (e.g. a modest drop in temperature) that probably have little effect on resource availability45,46. Masting also appears to have evolved in some species as a means of satiating predators or of facilitating pollination7. A recent model by Isagi et al.47 postulated that plant species ...

First, protected predators versus human use captures conflicts that occur when humans and predators compete for the same resource. Second, protected predator versus protected prey illustrates ma ...

... The lizards sit in, or near, their holes while waiting for prey, such as insects, to pass by. The presence of the lizards in a grassland is related to the structure of the grassland, rather than the type of grasses present. Grasslands with open spaces between tussocks are favoured, because the lizar ...

Molecular ecology

Molecular ecology is a field of evolutionary biology that is concerned with applying molecular population genetics, molecular phylogenetics, and more recently genomics to traditional ecological questions (e.g., species diagnosis, conservation and assessment of biodiversity, species-area relationships, and many questions in behavioral ecology). It is virtually synonymous with the field of ""Ecological Genetics"" as pioneered by Theodosius Dobzhansky, E. B. Ford, Godfrey M. Hewitt and others. These fields are united in their attempt to study genetic-based questions ""out in the field"" as opposed to the laboratory. Molecular ecology is related to the field of Conservation genetics.Methods frequently include using microsatellites to determine gene flow and hybridization between populations. The development of molecular ecology is also closely related to the use of DNA microarrays, which allows for the simultaneous analysis of the expression of thousands of different genes. Quantitative PCR may also be used to analyze gene expression as a result of changes in environmental conditions or different response by differently adapted individuals.
