Dynamic trait distribution as a source for shifts in interaction strength and population density [PDF]
arXiv, 2023 Intraspecific trait variation has been increasingly recognized as an important factor in determining species interaction and diversity. Eco-evolutionary models have studied the distribution of trait values within a population that changes over the generations as a result of selection and heritability.

Genetic mapping and evolutionary analysis of human-expanded cognitive networks
Nature Communications, 2019 Several cortical association areas have rapidly expanded in size during human evolution, including elements of the central cognitive default mode network (DMN).

Genetic mapping of cell type specificity for complex traits
Nature Communications, 2019 Tissue- and cell type-specific information helps to interpret findings from genome-wide association studies. Here, the authors leverage multiple single cell expression datasets to infer cell type specificity of traits.

Frontiers in Psychology, 2021 The purposes of the present study were three-fold: to examine (a) if the movement-specific reinvestment responses should be represented as two dimensional constructs, (b) whether dichotomization of the movement-specific reinvestment responses are ...

An Adaptive and Robust Method for Multi-trait Analysis of Genome-wide Association Studies Using Summary Statistics [PDF]
arXiv, 2022 Genome-wide association studies (GWAS) have identified thousands of genetic variants associated with human traits or diseases in the past decade. Nevertheless, much of the heritability of many traits is still unaccounted for. Commonly used single-trait analysis methods are conservative, while multi-trait methods improve statistical power by integrating

KCC2 expression levels are reduced in post mortem brain tissue of Rett syndrome patients
Acta Neuropathologica Communications, 2019 Rett Syndrome (RTT) is a neurodevelopmental disorder caused by mutations in the Methyl CpG binding protein 2 (MECP2) gene. Deficient K+-Cl—co-transporter 2 (KCC2) expression is suggested to play a key role in the neurodevelopmental delay in RTT patients’

On the Effect of Asymmetrical Trait Inheritance on Models of Trait Evolution [PDF]
Systematic Biology, 2019 AbstractCurrent phylogenetic comparative methods modeling quantitative trait evolution generally assume that, during speciation, phenotypes are inherited identically between the two daughter species. This, however, neglects the fact that species consist of a set of individuals, each bearing its own trait value.

Trait-trait dynamic interaction: 2D-trait eQTL mapping for genetic variation study [PDF]
BMC Genomics, 2008 AbstractBackgroundMany studies have shown that the abundance level of gene expression is heritable. Analogous to the traditional genetic study, most researchers treat the expression of one gene as a quantitative trait and map it to expression quantitative trait loci (eQTL). This is 1D-trait mapping.
