Anthropogenic and natural fragmentations shape the spatial distribution and genetic diversity of roe deer in the marginal area of its geographic range

Ecological Indicators, 2023
Habitat destruction and fragmentation are major factors in the destruction of genetic diversity and affect the movement behavior of the Roe deer population in the remaining habitats.

RETRACTED: An innovative panel containing a set of insertion/deletion loci for individual identification and its forensic efficiency evaluations in Chinese Hui ethnic minority

Molecular Genetics & Genomic Medicine, 2020
Background Individual identification is one of the most important tasks in the field of forensic genetics. Insertion/Deletion (InDel) polymorphism marker has been a promising marker for individual identification. However, a part of InDel loci in commonly

Genetic Diversity and Structure of Calophyllum brasiliense Along the Santa Catarina Coast

Floresta e Ambiente, 2019
Population genetics studies can provide knowledge in support of conservation efforts for plant populations. We studied the genetic diversity and structure in nine populations of Calophyllum brasiliense from Santa Catarina state, Brazil, aiming to ...

Development and characterization of microsatellite markers for Antennaria corymbosa (Asteraceae) and close relatives

Applications in Plant Sciences, 2019
Premise The genus Antennaria has a complex evolutionary history due to dioecism, excessive polyploidy, and the evolution of polyploid agamic complexes. We developed microsatellite markers from A.

A new method for ecologists to estimate heterozygote excess and deficit for multi‐locus gene families

Ecology and Evolution
The fixation index, FIS, has been a staple measure to detect selection, or departures from random mating in populations. However, current Next Generation Sequencing (NGS) cannot easily estimate FIS, in multi‐locus gene families that contain multiple loci

Numerical Solutions for Fractional Fixation Times in Evolutionary Models

Axioms
The fixation time of alleles is a fundamental concept in population genetics, traditionally studied using the Wright–Fisher model and classical coalescent theory.

Stronger selection can slow down evolution driven by recombination on a smooth fitness landscape. [PDF]

PLoS ONE, 2017
Stronger selection implies faster evolution-that is, the greater the force, the faster the change. This apparently self-evident proposition, however, is derived under the assumption that genetic variation within a population is primarily supplied by ...

Genetic structure and diversity of Calycolpus moritzianus (Myrtaceae) in the north-eastern Andes of Colombia

Revista Mexicana de Biodiversidad, 2021
The Arrayán tree (Calycolpus moritzianus) is an endemic species from northern South America and it is important for its potential in the medical and cosmetic industry.

An allozyme polymorphism is associated with a large chromosomal inversion in the marine snail Littorina fabalis

Evolutionary Applications, 2023
Understanding the genetic targets of natural selection is one of the most challenging goals of population genetics. Some of the earliest candidate genes were identified from associations between allozyme allele frequencies and environmental variation ...

Protein evolution depends on multiple distinct population size parameters

BMC Evolutionary Biology, 2018
That population size affects the fate of new mutations arising in genomes, modulating both how frequently they arise and how efficiently natural selection is able to filter them, is well established.
