Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

Why do people go to nature? Enhancing the recognition and scope of cultural ecosystem services in landscape

open access: yesPeople and Nature, Volume 8, Issue 3, Page 650-665, March 2026.
Abstract The cultural ecosystem services (CES) framework allows to systematically analyse non‐material human–nature relationships and can help to increase the recognition and scope of various intangible place‐based values. Although the amount of scientific literature addressing CES has increased over the last few decades, studies largely focus only on ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Groundwater Temperature Processes and Patterns: Implications for Stream Thermal Regimes

open access: yesWIREs Water, Volume 13, Issue 2, March/April 2026.
Shallow groundwater temperatures are controlled by ground surface temperatures and are influenced by climate change and land cover changes. Deeper groundwater temperature is constant year‐round, making it cooler (warmer) in the summer (winter) than surface water, and exhibits a lagged response to surface warming.
