Population Dynamics of Iran from Sociological Approach
This paper examines intergenerational transmission associated with population dynamics from sociological approach. The discussion is based on the analysis of observations in a country that has experienced substantial changes in family formation resulting in one of the world's most spectacular falls in women's birth rate ever experienced in human history: Iran. Facing fundamental historical expe...
متن کاملModeling Environmental Impacts of Plankton Reservoirs on Cholera Population Dynamics
Cholera remains a major public health problem with significant mortality, and numerous re-emergences have been observed in the last decade in many developing countries. Previous analyses have suggested a complex process for cholera disease emergence and spread, particularly related to environmental factors associated to aquatic habitats. To disentangle the complexity of these ecological and epi...
متن کاملHabitat-specific impacts of multiple consumers on plant population dynamics.
Multiple consumers often attack seeds, seedlings, and adult plants, but their population-level consequences remain uncertain. We examined how insect and small mammal consumers influenced the demography and abundance of the perennial shrub, bush lupine (Lupinus arboreus). In grassland and dune habitats we established replicate experimental lupine populations in 81-m2 plots that were either prote...
متن کاملEffect of genetic variance in plant quality on the population dynamics of a herbivorous insect.
1. Species diversity can affect many ecological processes; much less is known about the importance of population genetic diversity, particularly for the population dynamics of associated species. Genetic diversity within a host species can create habitat diversity; when associated species move among hosts, this variation could affect populations additively (an effect of average habitat) or non-...
متن کاملPopulation size is not genetic quality
Inbreeding depression is a phenomenon largely taken for granted among evolutionary geneticists (Conner & Hartl, 2004). For conservation biologists, the most important source of inbreeding comes when small population size leads to nonrandom mating among genotypes, either because available mates are related or because drift has reduced heterozygosity. Either process leads to the over-expression o...
