Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.

Phylogeography and Contact Zones of the Common Grass Snake in Poland (Squamata: Natricidae: Natrix natrix)

Zoologica Scripta, Volume 55, Issue 2, Page 209-219, March 2026.
ABSTRACT Until now, the genetic identity of common grass snakes (Natrix natrix) in Poland remained poorly understood. This study presents the first comprehensive phylogeographic analysis for Poland using mitochondrial DNA sequences (cyt b and ND4 + tRNAs) and 13 nuclear microsatellite loci.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

Oikos, Volume 2026, Issue 2, February 2026.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...

Qualifying Coal: Materiality and the Transformation of Import Supply Chains in Poland

Geo: Geography and Environment, Volume 13, Issue 1, January‐June 2026.
Short Abstract This article examines how the 2022 embargo on Russian coal reshaped coal supply and everyday energy provision in northern Poland. Drawing on ethnographic fieldwork, it shows how traders and households learned to work with unfamiliar coal varieties whose material properties differed from the Russian fuel they had previously relied on. The

The Kaliningrad Region as a Potential Coastal Transport Cluster

Baltic Region, 2014
The coastal regions of Russia, which ensure the country’s major export/import transactions, have potential for developing special forms of spatial organisation of regional transport system – transport clusters. This form of spatial organisation is better adapted (in comparison to a transport complex) to the ever-changing conditions of a competitive ...

Host–parasite oxidative arms race: who will win?

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Avian haemosporidian parasites are globally widespread with a broad repertoire of hosts. When infected, the host can either reduce (resistance) and/or limit the severity of parasitaemia (tolerance). Oxidative stress plays a pivotal role in the host's resistance and tolerance, as well as its detrimental endpoints.

Combined Evidence Reveals the Origin of a Rapid Range Expansion Despite Retained Genetic Diversity and a Weak Founder Effect

Molecular Ecology, Volume 34, Issue 19, October 2025.
ABSTRACT Many species are currently experiencing range shifts in response to changing environmental conditions with potentially serious genetic consequences. Repeated founder events and strong genetic drift are expected to erode genetic variation at the range front, reducing adaptive potential and slowing or even halting the expansion.
