Dwarf shrubs as bioindicators. [PDF]

Silva 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.

Chironomids as Indicators of Biodiversity and Isolation Patterns in a Balkan Karst Biodiversity Hotspot

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Our research aimed to assess the beta diversity of Chironomidae (Diptera) and faunal connections across springs, streams, and rivers within the Skadar Lake basin, a Mediterranean biodiversity hotspot, using DNA barcoding. Location Skadar Lake basin—a Mediterranean biodiversity hotspot. Methods We analysed mitochondrial cytochrome c oxidase

Use of Microbial Biofilms to Assess Groundwater Quality in Karstic Ecosystems

Environmental 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

Journal 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

The 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 ...

Bioindication of Heavy Metals in Soil by Liverworts [PDF]

Archives of Environmental Contamination and Toxicology, 1997
Studies were made of the accumulation of the heavy metals Ba, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb, Sr, V, and Zn and the macroelements N, P, K, Ca, and Mg in liverworts Conocephalum conicum, Marchantia polymorphia, and Pellia epiphylla collected from 57 microhabitats in Poland (Lower Silesia, Tatry Mts., and Puszcza Augustowska forest) and one microhabitat ...

Migratory Songbirds as Potential Ectozoochorous Protist Dispersal Vectors

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We demonstrate that migratory songbirds carry diatoms (Bacillariophyta) in their plumage, revealing an unexpected avian–algal association. All seven bird specimens we examined contained diatoms—224 frustules representing 25 genera and 9 orders, primarily freshwater, benthic pennates—some retaining chloroplasts prior to digestion and mounting (implying ...

Arcellinida testate amoebae in environmental DNA-based bioindication, from taxonomy free to haplotypic level

<p><span>Bioindication, evaluating biological responses to environmental disturbances, is crucial for assessing ecological status. While historical bioindication relied on macroscopic organisms, the introduction of environmental DNA (eDNA ...

Ostracod Genetic Variability in Response to Lake Level‐Driven Salinity Dynamics in Nam Co, Central Tibetan Plateau, in the Past Two Millennia

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Using sedimentary ancient DNA metabarcoding on a two‐millennia sediment core from Nam Co (Tibetan Plateau), the study reconstructs ostracod community shifts and genetic diversity in response to hydrological and climatic changes. Species richness peaked during moister intervals, while alternating dominance during the Medieval Climate Anomaly and Little ...
