Genetic variations in a species across geographic areas typically exhibit spatial clines. There is increasing interest inferring population genetic structure to understand the patterns of variation and evolution species. Here, we present da package propose infer using discriminant analysis (DA). We incorporate five supervised learning approaches (DAPC, LDAKPC, LFDA, LFDAKPC KLFDA) into within s...

A mathematical model describing the dynamics  of a  delayed  stage structure prey - predator  system  with  prey  refuge  is  considered.  The  existence,  uniqueness  and bounded- ness  of  the  solution  are  discussed.    All  the  feasibl e  equilibrium  points  are determined.  The   stability  analysis  of  them  are  investigated.  By  employ ing  the time delay as the bifurcation parame...

Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...

Information on the genetic structure of marine species is essential for stock improvement programs. In orderto analyses the genetic diversity of the Hawksbill turtle (Eretmochelys imbricte) by the microsatellite geneticmethod, 64 samples were caught from the beaches located in Kish and Qeshm islands. Polymerase chainreactions (PCR) of genomic DNA extracted from the samples wer...

Population structure parameters commonly used for diploid species are reexamined for the particular case of tetrasomic inheritance (autotetraploid species). Recurrence equations that describe the evolution of identity probabilities for neutral genes in an "island model" of population structure are derived assuming tetrasomic inheritance. The expected equilibrium value of FST is computed. In con...

kutum is considered as one of the anadramous species of the caspian sea. due to continuous population decline of the fish since 1975, iranian fisheries organization started to restock this species. nowadays, there is growing concern over the effects of restocking on natural populations. for this purpose, population structure and genetic variation of this species in the iranian coastline of casp...
