Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity
Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

CMiNet: An R package and user‐friendly Shiny App for constructing consensus microbiome networks
Methods in Ecology and Evolution, Volume 17, Issue 1, Page 52-66, January 2026.Abstract Microbial networks offer critical insights into community structure, ecological interactions and host–microbe dynamics. However, constructing reliable microbiome networks remains challenging due to variability among existing inference methods, limited overlap between inferred networks and the absence of a gold standard (a universally accepted ...

A New Method for the Exact Controllability of Linear Parabolic Equations
MathematicsThis work solves the exact controllability to zero in the final time for a linear parabolic problem when the control only acts in a part of the spatial domain. Specifically, it is proved, by compactness arguments, the existence of a partially distributed
