Natural Selection and Genetic Drift: Neutral and adaptive genetic variability of hatchery versus wild populations in brown trout Salmo trutta

Frontiers in Marine Science, 2015
Genetic drift and natural selection are two of the major forces shaping the genetic makeup of a population. Genetic drift reduces genetic variability due to the random loss of alleles during the transition from one generation to the next one. The smaller

Polygenic Adaptation in a Population of Finite Size

Entropy, 2020
Polygenic adaptation in response to selection on quantitative traits has become an important topic in evolutionary biology. Here we review the recent literature on models of polygenic adaptation.

Combining genetic and demographic monitoring better informs conservation of an endangered urban snake.

PLoS ONE, 2020
Conversion and fragmentation of wildlife habitat often leads to smaller and isolated populations and can reduce a species' ability to disperse across the landscape.

The effect of habitat and climatic on microsatellite diversity and allele length variation

Frontiers in Ecology and Evolution, 2022
Microsatellite loci have been shown to vary according to environment. We studied allelic length variation and diversity in eight microsatellite loci along a sharp climatic and habitat gradient in Israel, using the eastern spadefoot toad (Pelobates ...

Bottleneck‐associated changes in the genomic landscape of genetic diversity in wild lynx populations

Evolutionary Applications, 2021
Demographic bottlenecks generally reduce genetic diversity through more intense genetic drift, but their net effect may vary along the genome due to the random nature of genetic drift and to local effects of recombination, mutation, and selection.

Mechanisms driving spatial distribution of residents in colony biofilms: an interdisciplinary perspective

Open Biology, 2022
Biofilms are consortia of microorganisms that form collectives through the excretion of extracellular matrix compounds. The importance of biofilms in biological, industrial and medical settings has long been recognized due to their emergent properties ...

Do Arctic waders use adaptive wind drift? [PDF]

, 2004
We analysed five data sets of flight directions of migrating arctic waders in relation to winds, recorded by tracking radar and optical range finder, in order to find out if these birds compensate for wind drift, or allow themselves to be drifted by ...

Towards Drift Correction in Chemical Sensors Using an Evolutionary Strategy [PDF]

, 2010
Gas chemical sensors are strongly affected by the so-called drift, i.e., changes in sensors' response caused by poisoning and aging that may significantly spoil the measures gathered.

Genetic drift in mammals

Anais da Academia Brasileira de Ciências
: Genetic drift is the fortuitous occurrence of genetic events that when they become fixed modify the genome of populations. They can take the form of mutations of single nucleotides (SNPs), the insertion or deletion of short sequences (Indels) or the ...

Increasing pattern recognition accuracy for chemical sensing by evolutionary based drift compensation [PDF]

, 2011
Artificial olfaction systems, which mimic human olfaction by using arrays of gas chemical sensors combined with pattern recognition methods, represent a potentially low-cost tool in many areas of industry such as perfumery, food and drink production ...
