Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations

American Journal of Botany, Volume 113, Issue 4, April 2026.
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

A P-Q Arc Suppression Method Based on DC-Link Voltage Stability for Hybrid Multifunctional Arc Suppression Devices

Energies
The traditional arc suppression device suffers from high costs and low utilization. These problems can be effectively avoided by using a hybrid multi-function arc suppression device (HMF-ASD).

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, Volume 55, Issue 2, Page 356-383, April 2026.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Divergent Selection on Dispersal Targets Chemosensory and Neuronal Genes in Tribolium castaneum

Molecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Dispersal is key to the life history, ecology and evolution of many organisms and important in pest invasiveness. However, the genetic architecture underlying variation in dispersal behaviour remains poorly understood outside of a few model species.

Clarifying space use concepts in ecology: Range vs. occurrence distributions

Ecology, Volume 107, Issue 3, March 2026.
Abstract Quantifying animal movements is necessary for answering a wide array of research questions in ecology and conservation biology. Consequently, ecologists have made considerable efforts to identify the best way to estimate an animal's home range, and many methods of estimating home ranges have arisen over the past half a century.

Intrathecal idursulfase‐IT in children younger than 3 years with neuronopathic mucopolysaccharidosis II in a single‐arm, open‐label, phase 2/3 substudy and extension

JIMD Reports, Volume 67, Issue 2, March 2026.
Abstract Data from a phase 2/3, randomized, controlled, open‐label, multicenter trial in children with neuronopathic mucopolysaccharidosis II (MPS II; Hunter syndrome) older than 3 years suggested a benefit of intrathecal idursulfase‐IT on cognitive functioning in some patients. We describe a separate, parallel, open‐label, single‐arm, 52‐week substudy

EMT-Based Sequence Analysis of a Converter-Dominated Microgrid Under Fault and Load Disturbances: Case Study of the NELHA Microgrid

IEEE Access
Converter-dominated microgrids exhibit dynamic behaviors during faults and disturbances that differ fundamentally from those of synchronous-machine–dominated systems.
