The second prediction is simply based on the idea that bryozoans should grow faster and survive longer and thus have greater abundance in environments in which there is greater capture of food. A few studies have ...

Two toads with the same name makes conservation of the rare Puerto Rican toad difficult. To further increase awareness of the island’s uniqu ...

Further, comparison of these species groups with the corresponding model chondrichthyan group (pelagic-feeding chondrichthyans consisting of a wide variety of sharks, skates and rays) is a source of uncertainty in itself.

The effect of landscape complexity on aphids and on their natural enemies was analysed using mixed-effects models, in which we included landscape sector and field (nested within landscape sector) as random factors to account for the non-independent errors in our hierarchically nested designs.

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.
