Effective population size [PDF]
What is it? An aid to calculation in population genetics, introduced by Sewall Wright. The rate of change of the genetic make-up of a population by genetic drift – fluctuations in allele frequencies caused by random sampling – is inversely related to the effective population size, Ne. Ne is measured with reference to an ideal ‘Wright–Fisher’ population.

Do language change rates depend on population size? [PDF]
An earlier study (Nettle 1999b) concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets.

Calculation of the effective population size and estimating of total population size using mitochondrial DNA sequencing in Hamedan, Qazvin and Zanjan provinces [PDF]
Although wolves have the ability to live in different habitat types, in recent years their population has been drastically reduced in most parts of the country and in some areas has become extinct.

Estimating the Division Kernel of a Size-Structured Population [PDF]
We consider a size-structured population describing the cell divisions. The cell population is described by an empirical measure and we observe the divisions in the continuous time interval [0, T ].

FLUCTUATING POPULATION SIZE AND THE RATIO OF EFFECTIVE TO CENSUS POPULATION SIZE [PDF]
The effective size of a population (Ne) quantifies the rate at which genetic diversity is eroded by genetic drift (i.e., 112Ne per generation), a fundamental process of evolutionary change. Genetic diversity and its rate of decay have been linked with key components of population fitness (Allendorf and Leary 1987; Ralls et al. 1988; Briscoe et al. 1992;

Climate and local abundance in freshwater fishes [PDF]
Identifying factors regulating variation in numbers of individuals among populations across a species' distribution is a fundamental goal in ecology. A common prediction, often referred to as the abundant-centre hypothesis, suggests that abundance is ...

Effective Population Size of Korean Populations [PDF]
Recently, new methods have been developed for estimating the current and recent changes in effective population sizes. Based on the methods, the effective population sizes of Korean populations were estimated using data from the Korean Association Resource (KARE) project. The overall changes in the population sizes of the total populations were similar

POPULATION SIZE AND SURVIVAL RATES OF WILD TURKEY GOBBLERS IN CENTRAL MISSISSIPPI
: Knowledge of wild turkey (Meleagris gallopavo) population size and survival rates is needed to monitor trends and to evaluate management progress. To accomplish this, long‐term data sets are essential.
