Key variables considered in panel selection are geographic region, life stage, household size, age of "housewife," and social class.
Furthermore, clades A and B do not reflect any known ecological or behavioral differences (e.g., geographic region, life cycle, pheromone strain).
Poverty, poor education, low health knowledge, poor infrastructure, geographic factors, life style, and environmental factors (i.e., limited access to resources such as clean water) have been identified as primary factors contributing to the high incidence of infectious diseases among women in developing countries.
For example, the geographic and life history diversity of sockeye salmon (Oncorhynchus nerka, Walbaum, 1792) populations in Bristol Bay, Alaska have sustained a high aggregate productivity despite major changes in climatic conditions affecting the freshwater and marine environments during the last century (Hilborn et al. 2003).
The theory of evolution proposes a naturalistic explanation about the origin, diversification, and geographic distribution of life on Earth; life's biological processes result from natural selection, mutations, gene flow, and genetic drift (Mayr 2001).
Among the many potential consequences resulting from the geographic translocation of life forms is the spread of infectious disease organisms harbored by that life form.
There are many broods of periodical cicadas, with different geographic ranges and life cycles.
Scientists generally agree that there are five main factors that make primates, birds, bats and carnivores candidates for extinction: large body size; small geographic range; slow life cycle; high position in the food chain; and low population density.
A geographic information system – life cycle assessment method is used to quantify both the potential and the expected benefits of implementing rooftop greenhouses.
She spent four years collecting subjects and photographing them, taking care to ensure that a project focused on representation fulfilled its promise.
