Elevation shapes alpine snow algal blooms and their influence on albedo reduction

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Repositories of biocultural diversity: Toward best practices for empowering ethnobotany in digital herbaria

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1095-1103, July 2026.
Societal Impact Statement As herbaria digitize millions of plant specimens, ethnobotanical information associated with them is becoming increasingly accessible. These biocultural data include plant uses, names, and/or management practices of Indigenous Peoples and Local Communities (IPLCs).

Community‐driven variations in snow algae color modulate snow albedo reduction

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1739-1752, February 2026.
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

Epidermal Nevi and Epidermal Naevus Syndromes

open access: yesJEADV Clinical Practice, Volume 4, Issue 3, Page 669-680, August 2025.
ABSTRACT Epidermal nevi (EN) arise from postzygotic variants in ectoderm‐derived cell lines, such as keratinocytes and cells forming adnexa. EN may be present alone without any associated abnormality or be part of a syndrome. In this review, we will discuss about the clinical and genetics of the main types of EN and related syndromes.

Plant‐based meat analogues marketed in Catalonia: evaluation of the nutritional profile

open access: yesFood Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract In later years, a growing trend is apparent of vegetarian or vegan diets attributable to a number of causes, among of others, consumers’ concern for animal welfare, climate change and, to a lesser degree, for health‐related issues. On a par to this growth, availability of meat analogues in the market has also been on the rise. In this context,

Betz cells of the primary motor cortex

open access: yesJournal of Comparative Neurology, Volume 532, Issue 1, January 2024.
Betz cells are ‘gigantopyramidal’ extratelencephalic projection neurons of the primary motor cortex that are part of the monosynaptic cortico‐motoneuronal pathway in humans and other primates. Here, we provide a comprehensive overview of the historic and emerging position of Betz cells in the evolutionary, functional and molecular taxonomy of neurons ...
