Estimated six per cent loss of genetic variation in wild populations since the industrial revolution

Evolutionary Applications, 2019
Genetic variation is fundamental to population fitness and adaptation to environmental change. Human activities are driving declines in many wild populations and could have similar effects on genetic variation.

TLR7 gain-of-function genetic variation causes human lupus

Nature, 2022
Although circumstantial evidence supports enhanced Toll-like receptor 7 (TLR7) signalling as a mechanism of human systemic autoimmune disease1–7, evidence of lupus-causing TLR7 gene variants is lacking. Here we describe human systemic lupus erythematosus

Seasonal variation in wing size and shape of Drosophila melanogaster reveals rapid adaptation to environmental changes

Scientific Reports, 2022
Populations in seasonal fluctuating environments receive multiple environmental cues and must deal with this heterogenic environment to survive and reproduce.

The crucial role of genome-wide genetic variation in conservation

Proceedings of the National Academy of Sciences of the United States of America, 2021
The unprecedented rate of extinction calls for efficient use of genetics to help conserve biodiversity. Several recent genomic and simulation-based studies have argued that the field of conservation biology has placed too much focus on conserving genome ...

Inter‐ and intraspecific variation in mycotoxin tolerance: A study of four Drosophila species

Ecology and Evolution, 2022
Many mycophagous Drosophila species have adapted to tolerate high concentrations of mycotoxins, an ability not reported in any other eukaryotes. Although an association between mycophagy and mycotoxin tolerance has been established in many Drosophila ...

Modulated Expression of the Protein Kinase GSK3 in Motor and Dopaminergic Neurons Increases Female Lifespan in Drosophila melanogaster

Frontiers in Genetics, 2020
Most eukaryotic genes express multiple transcripts and proteins, and a sophisticated gene expression strategy plays a crucial role in ensuring the cell-specificity of genetic information and the correctness of phenotypes. The Drosophila melanogaster gene

Plant Conservation Practitioners Can Benefit from Neutral Genetic Diversity

Diversity, 2021
Several papers deal with a conservation genetics gap in which plant conservation and restoration managers or practitioners do not soundly integrate population genetics information into conservation management. Authors concerned about this issue point out

Genetic Variation

Population Genetics with R, 2020
An introduction to randomness and the neutral theory of molecular evolution and how it contributes to levels of genetic diversity in populations. The estimation of random shifts in allele frequencies over time is discussed using the binomial probability ...
