Effect of Transformation of Non‐Normal Fitness Trait Data on the Estimation of Genetic Parameters in Turkeys

open access: yesJournal of Animal Breeding and Genetics, Volume 142, Issue 6, Page 675-684, November 2025.
ABSTRACT Fitness traits described as a ratio often display non‐normal distributions; consequently, transformations are frequently applied to improve normality prior to the estimation of genetic parameters. However, the impact of different transformations on genetic parameter estimates depends on the dataset at hand.

An updated history of TDIF‐PXY signalling: a study in cell fate and tissue patterning

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1154-1165, November 2025.
Summary Non‐cell autonomous signalling is a mechanism by which stem cells are maintained across the tree of life. In plants, many stem cell populations are regulated by peptide ligands related to CLAVATA3, which are secreted from one cell type and bind to the leucine‐rich repeat domain of a plasma‐membrane‐localised receptor kinase related to CLAVATA1 ...

Highly parallel lab evolution reveals that epistasis can curb the evolution of antibiotic resistance

open access: yesNature Communications, 2020
Genetic perturbations that affect bacterial resistance to antibiotics have been characterized genome-wide, but how do such perturbations interact with subsequent evolutionary adaptation to the drug?

Mutation supply and the repeatability of selection for antibiotic resistance

open access: yes, 2017
Whether evolution can be predicted is a key question in evolutionary biology. Here we set out to better understand the repeatability of evolution. We explored experimentally the effect of mutation supply and the strength of selective pressure on the ...

Idiosyncratic epistasis creates universals in mutational effects and evolutionary trajectories

open access: yesNature Ecology & Evolution, 2020
Patterns of epistasis and shapes of fitness landscapes are of wide interest because of their bearings on a number of evolutionary theories. The common phenomena of slowing fitness increases during adaptations and diminishing returns from beneficial ...

From Individual to Stand Performance in Hybrids: Challenging the Optimal Parental Genetic Distance

open access: yesEvolutionary Applications, Volume 18, Issue 10, October 2025.
ABSTRACT Hybridization, the interbreeding of distinct genotypes, drives evolutionary processes like speciation and adaptation, potentially via phenotypic transgression, where hybrids exhibit novel traits. In crop breeding, research has largely focused on optimizing heterosis to enhance hybrid performance, particularly for traits such as biomass.

The Self-Organization of Interaction Networks for Nature-Inspired Optimization

open access: yes, 2009
Over the last decade, significant progress has been made in understanding complex biological systems, however there have been few attempts at incorporating this knowledge into nature inspired optimization algorithms.

Characterising Intraspecific Resource Use in a Rotifer Grazer Using High‐Throughput Phenotyping

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT 1. Understanding how adaptation to fluctuating resource availability drives life‐history trade‐offs, and in turn promotes niche differentiation among species, is central to ecology. The gleaner–opportunist framework, in which gleaners are better adapted to low resource levels and opportunists to high levels, represents one way in which ...

Misspecification in mixed-model based association analysis

open access: yes, 2015
Additive genetic variance in natural populations is commonly estimated using mixed models, in which the covariance of the genetic effects is modeled by a genetic similarity matrix derived from a dense set of markers.
