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.

Clonal interference and Muller's ratchet in spatial habitats

, 2014
Competition between independently arising beneficial mutations is enhanced in spatial populations due to the linear rather than exponential growth of clones.

Intrinsic adaptive value and early fate of gene duplication revealed by a bottom-up approach

eLife, 2018
The population genetic mechanisms governing the preservation of gene duplicates, especially in the critical very initial phase, have remained largely unknown.

No Population Genetic Structure of Skipjack Tuna (Katsuwonus pelamis) in the Tropical Western and Central Pacific Assessed Using Single Nucleotide Polymorphisms

Frontiers in Marine Science, 2020
Skipjack tuna (Katsuwonus pelamis) has historically been considered panmictic at the ocean basin scale because of the species’ life history and substantial absolute population size.

Comparing newly developed SNP barcode panels with microsatellites to explore population genetics of malaria parasites in the Peruvian Amazon

Frontiers in Genetics
IntroductionMalaria molecular surveillance (MMS) can provide insights into transmission dynamics, guiding national control programs. We previously designed AmpliSeq assays for MMS, which include different traits of interest (resistance markers and pfhrp2/

Drosophila yakuba mayottensis, a new model for the study of incipient ecological speciation

Fly, 2017
A full understanding of how ecological factors drive the fixation of genetic changes during speciation is obscured by the lack of appropriate models with clear natural history and powerful genetic toolkits.

X Chromatin inactivation in Menopause: A study on Hindu caste Bengalee population

Asian Journal of Medical Sciences, 2018
Background: Menopause being a physiologic event and eventually the prime time to perform risk assessment of chronic diseases and initiate preventive health measures. Previous studies reported, later menopause is independently associated to increased risk

Evolutionary Multiplayer Games

, 2014
Evolutionary game theory has become one of the most diverse and far reaching theories in biology. Applications of this theory range from cell dynamics to social evolution.

The inevitability of unconditionally deleterious substitutions during adaptation

, 2013
Studies on the genetics of adaptation typically neglect the possibility that a deleterious mutation might fix. Nonetheless, here we show that, in many regimes, the first substitution is most often deleterious, even when fitness is expected to increase in

Population Genetic Diversity of Two Marine Gobies (Gobiiformes: Gobiidae) from the North-Eastern Atlantic and the Mediterranean Sea

Journal of Marine Science and Engineering, 2020
Gobies (Gobiiformes: Gobiidae) are the most species-rich family of fishes in general, and the most abundant fish group in the European seas. Nonetheless, our knowledge on many aspects of their biology, including the population genetic diversity, is poor.
