Low genetic variation of invasive Fallopia spp. in their northernmost European distribution range

open access: yesEcology and Evolution, 2018
Knowledge about the reproduction strategies of invasive species is fundamental for effective control. The invasive Fallopia taxa (Japanese knotweed s.l.) reproduce mainly clonally in Europe, and preventing spread of vegetative fragments is the most ...

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

open access: yesNordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Development and validation of Triticum phytobiological method as an alternative procedure for investigating in vivo acute toxicity on mice [PDF]

open access: yes, 2017
The goal of this study was to validate an alternative method for determining in vivo acute toxicity using vegetal material instead of laboratory animals, starting from the phytobiological method known also as the Triticum technique.

Optimizing seeding ratios of field pea–brown mustard intercrops in Atlantic Canada

open access: yesAgronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Intercropping is a promising approach for ecological intensification that can enhance productivity and agroecosystem services. This study evaluated the agroecological performance of field pea (Pisum sativum) and brown mustard (Brassica juncea) intercropping across seeding ratios (0.5×, 1.0×, and 1.5× the recommended rates; 100 seeds m−2 ...
