Stronger selection can slow down evolution driven by recombination on a smooth fitness landscape. [PDF]

open access: yesPLoS ONE, 2017
Stronger selection implies faster evolution-that is, the greater the force, the faster the change. This apparently self-evident proposition, however, is derived under the assumption that genetic variation within a population is primarily supplied by ...

Bone and Soft Tissue Neoplasms in Infants Versus Older Children: A Report From the Cancer in Young People in Canada Program

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Infant bone and soft tissue neoplasms present distinct clinical challenges and lack large‐scale data to inform treatment decisions. This study aims to characterize bone and soft tissue neoplasms in infants in Canada and to compare their outcomes with those of older pediatric patients.

A new method for ecologists to estimate heterozygote excess and deficit for multi‐locus gene families

open access: yesEcology and Evolution
The fixation index, FIS, has been a staple measure to detect selection, or departures from random mating in populations. However, current Next Generation Sequencing (NGS) cannot easily estimate FIS, in multi‐locus gene families that contain multiple loci

Molecular population genetics of elicitor-induced resistance genes in European aspen (Populus tremula L., Salicaceae). [PDF]

open access: yesPLoS ONE, 2011
Owing to their long life span and ecological dominance in many communities, forest trees are subject to attack from a diverse array of herbivores throughout their range, and have therefore developed a large number of both constitutive and inducible ...

Therapeutic Apheresis in Nigeria: Awareness, Knowledge Gaps, and Readiness for Service Expansion Among Healthcare Professionals

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is a specialized extracorporeal blood purification modality used in the management of complex hematologic, neurologic, and autoimmune diseases. Despite established global guidelines, its utilization in Nigeria remains largely undocumented.

Development and characterization of microsatellite markers for Antennaria corymbosa (Asteraceae) and close relatives

open access: yesApplications in Plant Sciences, 2019
Premise The genus Antennaria has a complex evolutionary history due to dioecism, excessive polyploidy, and the evolution of polyploid agamic complexes. We developed microsatellite markers from A.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

An allozyme polymorphism is associated with a large chromosomal inversion in the marine snail Littorina fabalis

open access: yesEvolutionary Applications, 2023
Understanding the genetic targets of natural selection is one of the most challenging goals of population genetics. Some of the earliest candidate genes were identified from associations between allozyme allele frequencies and environmental variation ...
