Phenolic Iron Complexes Protect Glacier Ice Algae (Zygnematophyceae) Against Excessive UV and VIS Irradiation

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
We brought evidence that glacier ice alga Ancylonema alaskanum (Zygnematophceae) sequesters iron and forms organic metal complexes. We found that phenols were already present in the green Ancylonema alaskanum laboratory strain. Our study showed that their vacuole turned brownish due to enhanced iron‐phenol complexation under nutrient limitation with ...

Lead-210 in the atmospheric air of North and South Estonia: long-term monitoring and back-trajectory calculations; pp. 442–451 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2016
As the first study of long-term atmospheric 210Pb in Estonia, the activity concentration and possible origins of the nuclide were monitored at Tõravere, South Estonia, and Narva-Jõesuu, North-East Estonia, from 2001 to 2008.

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.

On approximation processes defined by a cosine operator function; pp 214–224 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2017
In this paper we introduce the Blackman- and Rogosinski-type approximation processes in an abstract Banach space setting. The historical roots of these processes go back to W. W. Rogosinski in 1926.

Carbon and nutrient solubility in live and dead Betula pubescens leaves across a boreal retrogressive chronosequence

open access: yesOikos, Volume 2025, Issue 5, May 2025.
Leaching – the release of elements from organic matter through dissolution in water – plays an important role in biogeochemical cycling and ecosystem processes. However, our limited understanding of the patterns and underlying drivers of element solubility in leaves hinders accurate predictions of leaching over space and time in terrestrial ecosystems.

High‐Resolution Tracking of Baltica's Northward Drift in the Ordovician

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract We investigated the paleogeography of Baltica via a paleomagnetic study of 471‐454 Ma limestones from the Siljan (Sweden) impact structure. Stepwise thermal demagnetization isolated a well‐defined magnetization component that unblocks up to the Curie temperature of magnetite and passes fold and reversal tests, indicative of a primary ...

Distribution and Diversity of Coastal Fish in Fresh and Oligohaline Waters: An Example of the Largest Baltic Sea Estuary of the Neva River

open access: yesEcology of Freshwater Fish, Volume 34, Issue 2, April 2025.
ABSTRACT Understanding how low salinity gradients (0‰–5‰) influence fish life cycles is critical for clarifying principles of fish assemblage formation in estuarine ecosystems. This study is intended to provide a foundation for predicting changes in fish populations amidst ongoing surface salinity decreases in the Baltic Sea. In the Neva River Estuary,
