‘Weed troubles’ in Palestine: Environmental imaginaries of the harmful weed

open access: yesGeographical Research, Volume 64, Issue 1, February 2026.
The control of weeds is a significant theme in Zionist environmental narratives of land redemption that have justified the appropriation of Palestinian land. This article explores how contemporary Palestinian artists revisit the environmental imaginaries of the “harmful weed” through the analysis of a Ramallah‐based exhibition titled Weed Control ...

Characterisation of Underground Organs as a Basis for Estimating Rhizome Resprouting Potential: The Case Study of Two Invasive Reynoutria Taxa (Polygonaceae)

open access: yesWeed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT The Japanese knotweeds (Reynoutria japonica complex; Polygonaceae) are characterised by a highly efficient vegetative propagation. Their resprouting capacity is associated with rhizomes, whose nodal structure distinguishes them from non‐regenerative roots.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Phenylacetonitrile from the Giant Knotweed, Fallopia sachalinensis, Infested by the Japanese Beetle, Popillia japonica, Is Induced by Exogenous Methyl Jasmonate

open access: yesMolecules, 2011
Phenylacetonitrile, (E)-b-ocimene, linalool, (E)-4,8-dimethyl-1,3,7-nonatriene and (E,E)-a-farnesene were identified as Japanese beetle, Popillia japonica, feeding-induced volatiles from the leaves of the giant knotweed, Fallopia sachalinensis, but not ...

The polyploid continuum and the landscape of polyploid genomic variation

open access: yesAmerican Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity inherent to ...

Identification of the presence and impact of Japanese knotweed on development sites [PDF]

open access: yesJournal of Building Survey, Appraisal & Valuation, 2010
Japanese knotweed is an alien species, which is spreading rapidly through the UK. Its root growth can penetrate many building materials, causing damage to infrastructure and buildings. This means that its discovery heralds potential property damage, increased costs and project delays.

Wetland Dissolved Organic Matter Fluorescence, Morphology, and Surrounding Land Use Linked to CH4 and N2O Concentrations in Agricultural Landscapes

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Freshwater wetlands process large amounts of nutrients originating from agricultural fields. Yet, these systems also have the potential to produce substantial amounts of nitrous oxide (N2O) and methane (CH4), both potent greenhouse gasses (GHGs).
