Proximity to wind turbines altered plant–pollinator dynamics in prairie and sagebrush ecosystems in Wyoming, USA

Nordic Journal of Botany, EarlyView.
Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...

Genetic analysis of the rare forest bryophyte Dicranum viride in the boreo‐nemoral zone near the northern distribution range limit

Nordic Journal of Botany, EarlyView.
Bryophytes are important forest ecosystem elements, being an integral part of biodiversity. Genetic studies contribute to bryophyte population ecology by helping to understand species historical distribution patterns and genetic diversity at different scales.

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

A new species and a synonym in Centaurea sect. Microlophus (Asteraceae, Cardueae–Centaureinae) from the Khuzestan Province, southwestern Iran

Nordic Journal of Botany, EarlyView.
A new species, Centaurea baghmalekensis Negaresh (Asteraceae) in C. sect. Microlophus (Cass.) DC., is described and illustrated from the Khuzestan Province, southwestern Iran. The new species is morphologically most similar to Centaurea pabotii Wagenitz, a recently described species from the Khuzestan Province.

Influence of Reaction Conditions and Water on the Manufacture of C9 Aromatic Hydrocarbon Resins

Polymer Engineering &Science, EarlyView.
Schematic representation of cationic polymerization process for the statistical analysis performed on material properties, showing the correlation plot of Softening point against Yield. ABSTRACT Aromatic hydrocarbons (HRs) find many commercial applications, demanding control of the cationic reaction conditions to achieve specific resin properties.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Periglacial Puzzles: Unravelling Environmental Controls on Alpine Solifluction Lobe Dimensions and Shape

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Freeze–thaw processes cause periglacial creep (otherwise known as solifluction) which forms solifluction lobes. These are lobate features characterized by a steep riser (front) and a smooth tread (body). Despite the widespread occurrence of these lobes, the controls on their morphometry remain poorly understood. Research into solifluction lobe
