Assessment Method for Leaf Litters Allelopathic Effect on Cyanobacteria [PDF]

open access: yes, 2005
A new bioassay technique combining leaf disk and softagar over-layer methods was developed to investigate the allelopathic effect of deciduous leaf litters on the growth of cyanobacteria ( Microcystis aeruginosa Kütz.).

Is a plant truly plastic? Nutrients and neighbours induce trait‐specific responses, but performance depends on response direction

open access: yesOikos, EarlyView.
Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

Chemically Mediated Plant–Plant Interactions: Allelopathy and Allelobiosis

open access: yesPlants
Plant–plant interactions are a central driver for plant coexistence and community assembly. Chemically mediated plant–plant interactions are represented by allelopathy and allelobiosis.

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

open access: yesPest Management Science, EarlyView.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...

Nanoemulsion design of Cynara cardunculus leaves extract rich in sesquiterpene lactones

open access: yesPest Management Science, EarlyView.
This work introduces a novel formulation strategy that advances the potential of Cynara cardunculus leaf extract enriched in sesquiterpene lactones as a bioherbicide and contributes to the broader development of sustainable weed management tools based on natural products.

Weed problems and possibilities for their control in salix for biomass [PDF]

open access: yes, 2012
Salix is a dedicated arable bioenergy crop that is presently grown on 12,000 ha in Sweden. It has probably the best environmental profile among the arable bioenergy crops grown in Sweden partly because neither fungicides nor insecticides are used in the ...

A review of the influence of root-associating fungi and root exudates on the success of invasive plants [PDF]

open access: yes, 2012
Plant-fungal interactions are essential for understanding the distribution and abundance of plants species. Recently, arbuscular mycorrhizal fungal (AMF) partners of non-indigenous invasive plants have been hypothesized to be a critical factor ...

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Allelopathic effect of the Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of germinated seedlings in Allium cepa L. [PDF]

open access: yes, 1999
The allelopathic activity of the different type of Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of A. cepa (IPA 6) germinated seedlings depends on their chemical composition and concentration, respectively.

An evolutionary perspective on the response‐effect framework

open access: yesFunctional Ecology, EarlyView.
Abstract The response‐effect framework (REF) has provided a foundational approach in functional ecology, using traits to predict how species respond to environmental factors (‘response traits’) and influence ecosystem functioning (‘effect traits’).
