Strong isolation by distance among local populations of an endangered butterfly species (Euphydryas aurinia)

open access: yesEcology and Evolution, 2021
The marsh fritillary (Euphydryas aurinia) is a critically endangered butterfly species in Denmark known to be particularly vulnerable to habitat fragmentation due to its poor dispersal capacity.

Use of biostimulants for water stress mitigation in two durum wheat (Triticum durum Desf.) genotypes with different drought tolerance

open access: yesPlant Stress
Agriculture is facing complex and unprecedented challenges, such as climate change and global population growth, associated with the increase of food demand. Durum wheat (DW) is a strategic crop for food security in the Mediterranean region. In this work,

Narrowing the wingless-2 mutation to a 227 kb candidate region on chicken chromosome 12. [PDF]

open access: yes, 2018
Wingless-2 (wg-2) is an autosomal recessive mutation in chicken that results in an embryonic lethal condition. Affected individuals exhibit a multisystem syndrome characterized by absent wings, truncated legs, and craniofacial, kidney, and feather ...

Contribution of common and rare variants to bipolar disorder susceptibility in extended pedigrees from population isolates. [PDF]

open access: yes, 2020
Current evidence from case/control studies indicates that genetic risk for psychiatric disorders derives primarily from numerous common variants, each with a small phenotypic impact. The literature describing apparent segregation of bipolar disorder (BP)

Genome-wide investigations reveal the population structure and selection signatures of Nigerian cattle adaptation in the sub-Saharan tropics

open access: yesBMC Genomics, 2022
Background Cattle are considered to be the most desirable livestock by small scale farmers. In Africa, although comprehensive genomic studies have been carried out on cattle, the genetic variations in indigenous cattle from Nigeria have not been fully ...

Marker Density and Read Depth for Genotyping Populations Using Genotyping-by-Sequencing [PDF]

open access: yesGenetics, 2013
Abstract Genotyping-by-sequencing (GBS) approaches provide low-cost, high-density genotype information. However, GBS has unique technical considerations, including a substantial amount of missing data and a nonuniform distribution of sequence reads.

Using genotyping-by-sequencing to understand Musa diversity : [P449] [PDF]

open access: yes, 2014
This project is part of a larger effort to apply genomics technologies to assess genetic diversity and to advance genetic improvement efforts in Musa (banana and plantain), a major staple food crop in the developing world.

The genetic basis of host preference and resting behavior in the major African malaria vector, Anopheles arabiensis [PDF]

open access: yes, 2016
Malaria transmission is dependent on the propensity of Anopheles mosquitoes to bite humans (anthropophily) instead of other dead end hosts. Recent increases in the usage of Long Lasting Insecticide Treated Nets (LLINs) in Africa have been associated ...

Chronic radiation exposure at Chernobyl shows no effect on genetic diversity in the freshwater crustacean, Asellus aquaticus thirty years on

open access: yesEcology and Evolution, 2019
Analysis of genetic diversity represents a fundamental component of ecological risk assessments in contaminated environments. Many studies have assessed the genetic implications of chronic radiation exposure at Chernobyl, generally recording an elevated ...

Continent‐wide population genomic structure and phylogeography of North America’s most destructive conifer defoliator, the spruce budworm (Choristoneura fumiferana)

open access: yesEcology and Evolution, 2020
The spruce budworm, Choristoneura fumiferana, is presumed to be panmictic across vast regions of North America. We examined the extent of panmixia by genotyping 3,650 single nucleotide polymorphism (SNP) loci in 1975 individuals from 128 collections ...
