Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

When alien plants become health hazards: An applied study on toxic and allergenic risks in Italy

PLANTS, PEOPLE, PLANET, EarlyView.
Alien plants are often studied for their ecological harm, but their risks to human and animal health remain poorly documented. This study provides the first comprehensive catalogue of poisonous and allergenic alien plants in Italy, identifying which species are dangerous, where they grow and who is most at risk—from children in city parks to pets and ...

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...

Allelopathy and phytotoxicity of Zanthoxylum rhoifolium Lam.

, 2012
In Cerrado, Zanthoxylum rhoifolium Lam. stands out because it interferes with the growth and development of other plants. The preliminary phytochemical analyses showed the presence of polyphenols and flavonoids. The Z.

Earlier spring may explain dominance of the slow‐growing dinoflagellate Naiadinium polonicum over the cyanobacterium Microcystis during a heatwave

Journal of Phycology, EarlyView.
Abstract Global warming and extreme weather events have been linked to a rise in cyanobacterial blooms, which threaten water quality and ecosystem services. However, during an extreme hot and dry summer, Microcystis was outcompeted by a dinoflagellate, Naiadinium polonicum, in a drinking water lake in southern Sweden.

Allelopathy and its application as a weed management tool: A review

Frontiers in Plant Science, 2022
Weeds are a serious threat to crop production as they interfere with the crop growth and development and result in significant crop losses. Weeds actually cause yield loss higher than any other pest in crop production.

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.

Allelopathy in constitution of plant communities

, 2023
Allelopathy, the ability of some plants to decrease the fitness of other plants by secondary metabolites, has been known for a very long time. The scientific community paid great attention to its research.
