The expected numbers of different categories of polymorphic sites are derived for two related models of population history the isolation model, in which an ancestral population splits into two descendents, and the size-change model, in which a single population undergoes an instantaneous change in size. For the isolation model, the observed numbers of shared, fixed, and exclusive polymorphic si...

BACKGROUND Growth parameters at birth are important for clinical decision-making. In Sri Lanka, the data from the World Health Organization (WHO) Multicentre Growth Reference Study (MGRS) are used to interpret these measurements. MATERIALS AND METHODS A descriptive cross-sectional study was conducted between September and October 2010 in hospitals of Gampaha district, Sri Lanka. The weight, l...

to provide reliable information concerning reproductive potential of hippodamia variegata goeze and its prey (aphis fabae), their related life tables were studied under controlled laboratory conditions (at 23?c). the unprocessed data of life tables were analyzed taking the euler-lotka as the basis model. standard error of population growth parameters was calculated using the jackknife re-sampli...

In this study, some growth parameters have been investigated like sex distribution, length and weight relationship, age determination, von Bertalanffy condition factor of Capoeta umbla (Heckel, 1843) (644 female, 743 male) captured from Pülümür River between 2017 2019. Females varied 7.1 to 38.8 cm in total 3.4 514.2 g weight. Males 7.3 38.3 3.5 450.4 The ratio (females/males) for C. was 1:1.15...
