Leaf size in mosses is structurally constrained by cell dimensions and genome size

open access: yesPlant Biology, Volume 28, Issue 2, Page 420-431, March 2026.
Cell size and midribs are the main mechanical determinants of moss leaf size, which itself depends on growth form and genome size; together, these relationships underpin key aspects of moss ecology and performance. Abstract Leaf anatomy is a key factor determining plant ecology.

Hyper‐Reduced Model Based on the Proper Orthogonal Decomposition and the LU Factorization Applied to the Neutron Diffusion Eigenvalue Problem

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT An efficient method for solving large eigenvalue problems efficiently can be developed using hyper‐reduced order models, such as those arising from the LU Proper Orthogonal Decomposition (LUPOD). The LUPOD employs dominant orthogonal modes along with a flexible number of collocation points to establish a reduced scalar product, thereby ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

open access: yesAmerican Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Biosynthesis of Silver Nanoparticles Using Black Pepper (Piper nigrum) Seed Extract and Evaluation of Their Cytotoxicity

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study reports the green biosynthesis of piperine‐functionalized silver nanoparticles from Piper nigrum seed extract, followed by comprehensive physicochemical characterization and in vitro cytotoxic evaluation. The results confirm successful nanocomposite formation and demonstrate a marked enhancement of cytotoxic activity against gastric cancer ...

Roots of resilience: Assessing child and adolescent nature connectivity in the Mediterranean Region of Murcia (Spain)

open access: yesPeople and Nature, Volume 8, Issue 2, Page 378-391, February 2026.
Abstract Children today spend less time outdoors than previous generations, with potential consequences for health, learning and pro‐environmental attitudes. We assessed children's connection with and exposure to nature in a Mediterranean setting using the Nature Connection and Experience Index (NCEI), a composite measure that integrates an affective ...

Does ecology predict taxonomy? How ecological differentiation can be used to spatially infer intraspecific diversity

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 518-530, February 2026.
Abstract Assessing the true dimension of biodiversity is a major challenge. Many species hide within them a diversity that is now being uncovered using molecular data. However, population genetic studies tend to be resource‐consuming and more difficult to apply to a broader range of taxa, limiting scalability.
