Distinct Patterns of Symbiosis-Related Gene Expression in Actinorhizal Nodules from Different Plant Families

Molecular Plant-Microbe Interactions, 2003
Phylogenetic analyses suggest that, among the members of the Eurosid I clade, nitrogen-fixing root nodule symbioses developed multiple times independently, four times with rhizobia and four times with the genus Frankia.

Significance of diarylheptanoids for chemotaxonomical distinguishing between Alnus glutinosa and Alnus incana [PDF]

Holzforschung, 2017
Abstract Diarylheptanoids are a group of secondary metabolites widely distributed in the Betulaceae family and characteristic for Alnus species. In this study, the chemotaxonomic power of diarylheptanoids, such as hirsutanonol-5-O-β-d-glucopyranoside, rubranoside A, oregonin, platyphylloside, alnuside A and hirsutanonol, has been ...

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

The Immunological Correlation With Adenoid Hypertrophy and Allergic Rhinitis in Children

iNew Medicine, Volume 2, Issue 1, March 2026.
The imbalance of Th1/Th2 and Th17/Treg cells in allergen and inflammatory responses might be associated with the development of adenoid hypertrophy, suggesting that allergic rhinitis maybe the risk factor of AH and providing a potential alternative explanation for adenoid hypertrophy pathogenesis.

Mapping the next forest generation reveals multiple regeneration gaps across German forests

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Our study provides the first nationwide, high‐resolution assessment of forest regeneration, offering a valuable baseline for monitoring forest development. The regeneration density and indicator maps enable forest managers and policymakers to identify regeneration deficits, prioritise adaptive management interventions and contribute to the development ...

Apparent Flexibility of Fatty Acid Metabolism in Shredders Depends on Terrigenous Organic Matter Type

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Headwater streams receive large amounts of terrestrial organic matter (tOM) such as leaves from a dense riparian matrix, forming a critical link between terrestrial and aquatic ecosystems. Terrestrial OM rarely provides essential macronutrients such as polyunsaturated fatty acids (PUFAs), and microbial colonisation of tOM is an important ...

Unmanaged forest swamps benefit saproxylic and soil‐inhabiting crane fly communities

Insect Conservation and Diversity, Volume 19, Issue 2, Page 349-359, March 2026.
Species richness of both saproxylic and soil‐inhabiting crane flies was consistently higher in unmanaged forests across all habitat types. Soil‐inhabiting species thrived in swamps and ditches, while saproxylic richness was linked to low light and high soil moisture, independent of habitat type.

Effects of Ungulate Herbivores on Temperate Forest Understory Vegetation—Implications From a Large‐Scale Wildlife Exclosure Experiment in Central Europe

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Fenced ungulate exclosure (foreground) with unfenced control plot (background). ABSTRACT Question Ungulates play a key role in influencing understory vegetation and ecosystem dynamics in temperate forests. However, how soil conditions modulate ungulate effects on understory communities remains insufficiently understood.

Phytophthora alni Infection Reinforces the Defense Reactions in Alnus glutinosa-Frankia Roots to the Detriment of Nodules

Molecular Plant-Microbe Interactions
Alnus glutinosa, able to establish symbiosis with mutualistic bacteria of the genus Frankia, is one of the main species in European riparian environments, where it performs numerous biological and socioeconomic functions.
