Rapid Structural Analysis of Natural Products Using MicroED

Small, EarlyView.
The cryoEM method, MicroED used for rapid analysis and structure determination of natural products that remained unattainable by other structural biology methods ABSTRACT Structural analysis of natural products remains challenging due to their inherent complexity and limited availability.

Historical climate change and vicariance events contributed to the intercontinental disjunct distribution pattern of ash species (Fraxinus, Oleaceae)

Communications Biology
The Northern Hemisphere temperate forests exhibit a disjunct distributional pattern in Europe, North America, and East Asia. Here, to reveal the promoter of intercontinental disjunct distribution, Fraxinus was used as a model organism to integrate ...

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

The Chemical Record, EarlyView.
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 ...

Chemical Composition and Antioxidant Activity of Fraxinus ornus L. and Fraxinus excelsior L. [PDF]

Kemija u Industriji
In this work, the total content of phenolics, flavonoids, and phenolic acids in the leaves and bark extracts of Fraxinus ornus L. and Fraxinus excelsior L. was determined. In addition, the identification and quantification of phenolic acids was performed

The phylogeny and biogeographic history of ashes (fraxinus, oleaceae) highlight the roles of migration and vicariance in the diversification of temperate trees. [PDF]

PLoS ONE, 2013
The cosmopolitan genus Fraxinus, which comprises about 40 species of temperate trees and shrubs occupying various habitats in the Northern Hemisphere, represents a useful model to study speciation in long-lived angiosperms.

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting

Wildlife Biology, EarlyView.
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Riparian reference condition: Using regional plant composition to guide functional improvements in the City of Austin [PDF]

, 2011
This technical report focuses on ways to restore riparian habitat within specific Austin creeks. This study is designed to serve as a template for restoration efforts with other urbanized creeks (Waller).As a result of an expanding and rapidly urbanizing
