Organisms within the trophic network are arranged into populations and communities.
However, the rise in obesity in populations worldwide since the 1980s has outpaced the rate at which genetic mutations are normally incorporated into populations on a large scale.
"It is a cautionary tale that you have to think about the possibility of plants escaping into populations where there are wild relatives present," said Jay Reichman, an agency ecologist who is the lead author of a study to be published in the journal Molecular Ecology.
Ecological impact of transgene flow into populations of wild/weedy relatives is associated with fitness effects in hybrid progeny.
Molecular and cellular-level processes combine into populations of neurons connected through brain systems and subsystems to generate behaviors that range from simple movements to social interactions.
These approaches are based on reference samples that are grouped into populations or other aggregates and intend to identify the most likely group of origin.
We describe the reach of RDS into populations of youth who may be missed by traditional household- and school-based sampling.
"Functional" refers to a primarily concern with ecosystem and evolutionary processes, while "compositional" sees organisms as aggregated into populations, species, higher taxa, communities, and other categories.
We developed a model including these factors to assess their impact on the process of Wolbachia spread into populations of three mosquito species (Anopheles gambiae, Aedes aegypti and Culex pipiens).
One of the big bones of contention with a lot of consumer services from startups is that they tend to focus on urban areas — the idea being that big cities give them a better shot at achieving critical mass and tapping into populations of overworked people with more disposable income.
Race is a subject matter but representation is so much more important when you come into populations that are predominately white".
