Evaluating the role of frequency‐dependent selection in controlling the expansion of clonal aggregations in the tropical forest's understorey: Insights from a decade‐long experiment

Functional Ecology, Volume 39, Issue 3, Page 851-862, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual reproduction, despite its associated costs and risks, is prevalent among many organisms, presumably to generate and maintain genetic diversity. This diversity is vital for adapting to environmental changes and combating natural enemies.

Skin barrier, phenotypic and genotypic characterisation of autosomal recessive ichthyosis in TGM1‐deficient Jack Russell Terriers and response to topical ceramide

Veterinary Dermatology, Volume 35, Issue 6, Page 617-625, December 2024.
Background – Autosomal recessive ichthyosis leads to structural or biochemical changes that impair skin barrier function. Hypothesis/Objectives – To assess (1) the phenotype and genotype in a litter of Jack Russell Terriers with autosomal recessive congenital ichthyosis (ARCI), and (2) the defective skin barrier and determine if a topical ceramide can ...

Geographic variation in developmental plasticity among populations of the canyon treefrog in response to temperature and pond‐drying

Journal of Zoology, Volume 324, Issue 2, Page 103-117, October 2024.
This study focuses on the responses of the canyon tree frog (Dryophytes arenicolor) larvae to temperature and pond‐drying. Conducting a common garden experiment with larvae from three distinct populations, we found significant geographic variation in plastic responses and observed that populations exhibit specific responses to each treatment in both ...

Sequencing vs. amplification for the estimation of allele dosages in sugarcane (Saccharum spp.)

Applications in Plant Sciences, Volume 12, Issue 5, September-October 2024.
Abstract Premise Detecting single‐nucleotide polymorphisms (SNPs) in a cost‐effective way is fundamental in any plant breeding pipeline. Here, we compare three genotyping techniques for their ability to reproduce the allele dosage of SNPs of interest in sugarcane (Saccharum spp.).
