Does ecology reach all the way down to the subatomic scale?

Imagine you could stop being human-sized for a while and shrink down to the size of a bacterium, roughly one-millionth of your current stature. At this scale, you would stop being bound by gravity and instead discover that ...

How do mushrooms contribute to global warming?

Global warming is increasing with each day that passes and the poles begin to thaw. There has been little research into the harm caused by fungi (mold that contribute to the production of greenhouse gases.

The origins of abiotic species

How can life originate from a lifeless chemical soup? This question has puzzled scientists since Darwin's 'Origin of species'. University of Groningen chemistry professor Sijbren Otto studies 'chemical evolution' to see if ...

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, 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 simultaneously analysis of the expression of thousands of different genes. real-time polymerase chain reaction may also be used to analyze gene expression as a result of changes in environmental conditions or different response by differently adapted individuals.
