Dwarf shrubs as bioindicators. [PDF]

open access: yesSilva Fennica, 1981
Several studies of air polluted forest environments have shown that dwarf shrubs suffer from air pollution. In many cases the disturbances have been attributed to the susceptibility of the dwarf shrubs, while in some cases the vegetational competition factor has been discussed.

Bioindicators and environmental protection [PDF]

open access: yesE3S Web of Conferences, 2020
The plants capable to occlude the maximum quantity of the heavy metals (HM) from soil solution are studied. Plants - indicators of accumulation of heavy metals are allocated, the new directions on decrease in toxicity of the soil are offered. For the purpose of studying of sorption abilities of bean herbs studied accumulation of heavy metals on phases ...

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.
