The Mantle Transition Zone in Fennoscandia: Enigmatic High Topography Without Deep Mantle Thermal Anomaly

Geophysical Research Letters, 2019
Seismological data acquired by dense receiver networks in Fennoscandia enable imaging of Earth's upper mantle structure at unprecedented resolution and provide critical observations for resolving the ongoing debate on the cause of enigmatic high ...

Herbariomics and the peculiar case of Alisma wahlenbergii (Alismataceae)

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Species identification and delimitation in aquatic plants can be challenging due to their often simple, plastic, and convergent morphology. This has led to varying taxonomic opinions in many genera, including Alisma. One debated case is the narrowly endemic A. wahlenbergii, which occurs submerged in the Baltic Sea region.

Influence of allochtonous nutrients delivered by colonial seabirds on soil collembolan communities on Spitsbergen [PDF]

, 2012
Despite a widespread recognition of the role of seabird colonies in the fertilization of nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities are still ...

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Polyploid races, genetic structure and morphological features of earthworm Aporrectodea rosea (Savigny, 1826) (Oligohaeta: Lumbricidae) in Ukraine [PDF]

, 2011
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm A. rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking.

Checklist of terrestrial Parasitengona mites in Fennoscandia with new species- and distribution records (Acariformes: Prostigmata)

Biodiversity Data Journal, 2019
The knowledge of terrestrial Parasitengona in Fennoscandia lies far behind that of their aquatic counterparts, the water mites (Hydrachnidia). Based on new inventories, we provide primary data and an annotated checklist of terrestrial Parasitengona in ...

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.
