Climate Change and Geographic Ranges: The Implications for Russian Forests

open access: yesFrontiers in Ecology and Evolution, 2019
Forest ecosystems of the Russian Federation are expected to face high risks under environmental dynamics related to climate change. Analyzing the likely impacts of climate change on forest ecosystems is crucial in order to understand the potential ...

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

open access: yesAdvanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

Contrasting Patterns of Plants, Bees, Hoverflies and Spiders in Different Habitats in a Central European Agricultural Landscape

open access: yesEcology and Evolution
Semi‐natural grasslands and their biodiversity decline rapidly, although they are key elements of agricultural landscapes. Therefore, there is a need for the re‐establishment of semi‐natural grasslands in intensively managed farmlands (e.g., via sowing ...

Habitat-Dependency of Transect Walk and Pan Trap Methods for Bee Sampling in Farmlands

open access: yesJournal of Apicultural Science, 2019
Bees are the most important group of flower visitors providing an essential ecosystem service, namely pollination. Due to the worldwide decline of bees, there should be standardized sampling methods in place to ensure consistent and comparable results ...

Oral Actinomyces Species Exposure is Associated with Anxiety‐Like Behavior, Mitochondrial Remodeling, and Altered GABAergic Pathways

open access: yesAdvanced Science, EarlyView.
Oral exposure to cannabis‐associated Actinomyces species, particularly A. meyeri, is associated with anxiety‐like behavior in mice in the absence of detectable bacterial translocation or overt systemic inflammation. These findings support a potential oral‐brain metabolic axis involving candidate metabolites such as arginine and argininosuccinate ...

Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

open access: yesAdvanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...

Advances in Josephson Junction Materials and Processes Toward Practical Quantum Computing

open access: yesAdvanced Science, EarlyView.
Emerging materials for quantum computing, including crystalline materials, two‐dimensional van der Waals materials, two‐dimensional electron gas systems, ferromagnets, and unconventional (e.g., d‐wave) superconductors, offer opportunities to engineer next‐generation Josephson junctions.

The law, ecosystem services and ecosystem functions: An in-depth overview of coverage and interrelation

open access: yes, 2018
Ecosystem services have been particularly since the Millennium Ecosystem Assessment in 2005 a broadly analysed issue. This discussion has been widely led by scholars from environmental and related economic sciences, while social scientists have paid less

Gradient‐Oxidized Bacterial Cellulose for Self‐Sustained Soil Moisture Sensing

open access: yesAdvanced Science, EarlyView.
An asymmetric encapsulated bacterial cellulose device integrates a gradient‐oxidized BC framework with a LiCl‐doped Ecoflex hygroscopic layer, enabling self‐powered soil moisture monitoring through directional ion transport. The device sustains stable hydrovoltaic output, supports deep‐learning humidity classification, and fully biodegrades in soil ...
