Tracing change in the public perception of plants: insights from archives and social media in China

PLANTS, PEOPLE, PLANET, EarlyView.
As urbanization accelerates, historic gardens serve as vital cultural treasures that offer spiritual and cultural support to the public. This study proposes an innovative approach that merges historical records from the Qing Dynasty with contemporary social media data to explore changes in public perceptions of these gardens.

Projected Temperature and Precipitation Expand Modeled Distributions of Reynoutria spp. While Modeled Distribution Changes for Ludwigia spp. Are Scenario‐Dependent at Watershed Scales in the Pacific Northwest, USA

River Research and Applications, EarlyView.
ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...

Antioxidant Potential of Bark Extracts from Boreal Forest Conifers

Antioxidants, 2013
The bark of boreal forest conifers has been traditionally used by Native Americans to treat various ailments and diseases. Some of these diseases involve reactive oxygen species (ROS) that can be prevented by the consumption of antioxidants such as ...

Simultaneous Real-Time Measurement of Isoprene and 2-Methyl-3-Buten-2-ol Emissions From Trees Using SIFT-MS

Frontiers in Plant Science, 2020
The C5 hemiterpenes isoprene and 2-methyl-3-buten-2-ol (MBO) are important biogenic volatiles emitted from terrestrial vegetation. Isoprene is emitted from many plant groups, especially trees such as Populus, while emission of MBO is restricted to ...

Analysis of the WUSCHEL-RELATED HOMEOBOX gene family in the conifer picea abies reveals extensive conservation as well as dynamic patterns

BMC Plant Biology, 2013
BackgroundMembers of the WUSCHEL-RELATED HOMEOBOX (WOX) gene family have important functions during all stages of plant development and have been implicated in the development of morphological novelties during evolution.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

ANALYSIS OF POLYMORPHISM OF ORGANELLE DNA TO ELUCIDATE THE PHYLOGEOGRAPHY OF NORWAY SPRUCE IN THE EAST EUROPEAN PLAIN

Вавиловский журнал генетики и селекции, 2015
The history of Norway spruce distribution in the East European plain is discussed with regard to the results of allele diversity survey of the mitochondrial Nad1 gene, which is maternally inherited, and the chloroplast trnT-trnF region, which is ...

Lignin studies of transgenic Norway spruce [PDF]

, 2006
An attractive objective in tree breeding is to reduce the content of lignin, or increase its extractability, to favor delignification during pulping. This study investigates the potential for lignin alterations in Norway spruce (Picea abies [L.] Karst ...

Composition of psocid taxocenoses (Insecta: Psocoptera) in dependence on the level of naturalness of forest ecosystems in the Žďárské vrchy hills

Journal of Forest Science, 2003
In 1999-2000 in the Protected Landscape Area (PLA) Žďárské vrchy hills the occurrence of psocids (Psocoptera) was studied in different types of biotopes: natural forest ecosystems (stands of Fagus sylvatica with individual admixture of Abies alba, Acer ...
