Looking backward to move forward: Enhancing metadata in scientific collections through interdisciplinary collaboration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Early modern herbaria house important and useful data on historic environments. However, their contents are often inhospitable to scientific use. Despite this challenge, once their contents have been deciphered, such specimens present novel research opportunities.

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

NATURAL POLYACETYLENE COMPOUNDS

open access: yesФармация и фармакология (Пятигорск), 2015
In article the review of the initial stage of researches of natural polyacetylene compounds is resulted. The high reactionary ability leading to fast oxidation and degradation of these compounds, especially at influence of Uf-light, oxygen of air, pH and

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

open access: yesPest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Stability studies of cynaropicrin–major sesquiterpene lactone of Cynara cardunculus leaves

open access: yesPest Management Science, EarlyView.
This study investigated its stability under high temperature and pH, mimicking agronomic extremes and under soil context. Bioassays demonstrated that degradation products exhibited higher phytotoxic activity than cynaropicrin and deacylcynaropicrin. This is the first study about cynaropicrin's stability, characterizing degradation products, and their ...

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

open access: yesPest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

open access: yesPest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

open access: yesZoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...
