Several predator species at risk of extinction in Southwestern Europe are dependent on the population density of European wild rabbits Oryctolagus cuniculus. Rabbit populations in the region, however, have recently undergone dramatic decreases in population density, which may be exacerbated by hunting. Current hunting policies set the autumn–winter season, just before the start of rabbit reprod...

Despite considerable speculation virtually nothing is known about the empirical relationship between traditional Tibetan administrative systems, household processes, and demographic trends in historical Tibetan populations because indigenous data sources have never been systematically analyzed. This article examines a 1958 tax register from Kyirong, formerly a district-level political division ...

background: omeprazole is metabolized predominantly by cyp2c19, a polymorphically expressed enzymes that show marked interindividual and interethnic variation. these variations cause a substantial differences that have been reported in the pharmacokinetics of omeprazole. the aim of the present study was to evaluate the pharmacokinetic parameters of omeprazole in a random iranian population. met...

the relationship between population structure and violent conflict is complex and heavily dependent on the behavior of other variables like governance, economic prospects, and urbanization. while addressing rapid population growth might be a necessary condition for peace, it is by no means sufficient. concomitant steps must also be taken to foster inclusivity, guarantee broader rights for all, ...

The population growth rate, or intrinsic rate of increase, is the rate of growth that will be achieved by a population with fixed vital rates. The sensitivity of population growth rate to changes in the vital rates can be written in terms of the stable stage or age distribution and the reproductive value distribution. If the vital rate measures the rate of production of one type of individual b...

The evolution of population dynamics in a stochastic environment is analysed under a general form of density-dependence with genetic variation in r and K, the intrinsic rate of increase and carrying capacity in the average environment, and in sigma(e)(2), the environmental variance of population growth rate. The continuous-time model assumes a large population size and a stationary distribution...

We study the qualitative properties of degenerate diiusion equations used to describe dispersal processes in population dynamics. For systems of interacting populations, the forms of the diiusion models used determine if the population will intermix or remain disjoint (segregated). The dynamics and stability of segregation boundaries between competing populations is analyzed. General population...

introduction: information on the sleepiness and sleep quality is limited for asians. this study was conducted to determine the prevalence of sleepiness and sleep quality among the adult population in iran. materials and methods: this is a descriptive and explorative design study in which 1100 participants randomly selected from the kerman city population in south –east of iran. using two questi...

age related skin disorders due to structural and functional changes in the skin of the elderly may increase health care costs. as a result of an increase in the number of aging population in iran, provision of dermatology services to the elderly group due to the limitation of resources and the high cost of those services will be a challenge for the health care system. moreover, by increasing th...
