Use of Microbial Biofilms to Assess Groundwater Quality in Karstic Ecosystems

open access: yesEnvironmental Microbiology, Volume 28, Issue 2, February 2026.
Analyses of prokaryotic diversity and community structures of biofilms showed variations linked to the nutrient and organic matter conditions in the studied karstic stations. Biofilms developed on artificial substrates appeared as promising indicators to assess groundwater quality in karst.

Species delimitation within the Achnanthidium minutissimum complex (Bacillariophyta), based on morphological, molecular, and ecophysiological approaches

open access: yesJournal of Phycology, Volume 62, Issue 1, Page 25-43, February 2026.
Abstract The benthic diatom species Achnanthidium minutissimum belongs to a species complex with a challenging taxonomy. Achnanthidium minutissimum has been reported to be a widespread and abundant species occurring in a broad range of freshwater habitats. However, differentiating and delimiting it from other Achnanthidium species is challenging due to

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

open access: yesThe Anatomical Record, Volume 309, Issue 1, Page 166-186, January 2026.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

Human Impact on Microinvertebrate Diversity and Distributions: Questioning the Resilience of Tardigrades

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 12, December 2025.
ABSTRACT Aim Tardigrades, commonly known as some of the toughest organisms on Earth, like many other microscopic invertebrates, are often overlooked in biodiversity monitoring. Our study aimed to elucidate the impact of environmental disturbance caused by anthropogenic activity on tardigrade diversity and distributions.

Comparative Proteomics of Salinity Stress Responses in Fish and Aquatic Invertebrates

open access: yesPROTEOMICS, Volume 25, Issue 21-22, Page 185-205, November 2025.
ABSTRACT Fluctuating salinity is symptomatic of climate change challenging aquatic species. The melting of polar ice, rising sea levels, coastal surface and groundwater salinization, and increased evaporation in arid habitats alter salinity worldwide. Moreover, the frequency and intensity of extreme weather events such as rainstorms and floods increase,
