Empty Niches after Extinctions Increase Population Sizes of Modern Corals
Large environmental fluctuations often cause mass extinctions, extirpating species and transforming communities [1, 2]. While the effects on community structure are evident in the fossil record, demographic consequences for populations of individual species are harder to evaluate because fossils reveal relative, but not absolute, abundances. However, genomic analyses of living species that have...
متن کاملPopulation Genetics with Fluctuating Population Sizes
Standard neutral population genetics theory with a strictly fixed population size has important limitations. An alternative model that allows independently fluctuating population sizes and reproduces the standard neutral evolution is reviewed. We then study a situation such that the competing species are neutral at the equilibrium population size but population size fluctuations nevertheless fa...

Background: There is lack of Iranian studies on marital satisfaction which is one of the important factors in the stability of marriage. The present study aimed to evaluate the effects of socio-demographic variables on marital satisfaction. Methods: This Analytical and cross-sectional study was conducted on 770 married people from Gonabad city, Northeast of Iran. Simple random sampling was us...
متن کاملA behaviorally explicit demographic model integrating habitat selection and population dynamics in california sea lions.
Although there has been a call for the integration of behavioral ecology and conservation biology, there are few tools currently available to achieve this integration. Explicitly including information about behavioral strategies in population viability analyses may enhance the ability of conservation biologists to understand and estimate patterns of extinction risk. Nevertheless, most behaviora...
متن کاملBayesian Zero- Inflated Poisson model for prognosis of demographic factors associated with using crystal meth in Tehran population
Background: Use of methamphetamine (MA) and other stimulants has increased steadily over the past 10 years. Risk factor evaluation to reduce the problem in the community is one solution to protect people from addiction. This study aimed at using Bayesian zero- inflated Poisson (ZIP) model to investigate the relationship between the number of using crystal meth and some demogr...
