The native flora of the Redberry Lake Biosphere Region (Saskatchewan, Canada): taxonomy, biogeography, habitats and conservation

open access: yesNordic Journal of Botany, EarlyView.
This study reports for the first time a checklist of native vascular plants and provides a comprehensive analysis of the flora of the Redberry Lake Biosphere Region (RLBR) in the province of Saskatchewan, Canada. To complete an inventory of the regional flora, I conducted intensive field investigations during 2010–2025 and employed detailed examination

Dynamic general equilibrium analysis of improved weed management in Australia's winter cropping systems [PDF]

open access: yes
A recent analysis indicated that the direct financial cost of weeds to Australia’s winter grain sectorwas approximately $A1.2bn in 1998–1999. Costs of thismagnitude represent a large recurring productivity loss in an agricultural sector that is ...

NO-TILL PROVIDES THE OPPORTUNITY TO MANAGE UNDERGROUND INTERACTIONS BETWEEN ARBUSCULAR MYCORRHIZAL FUNGI, WEEDS AND CROP PLANTS UNDER MEDITERRANEAN CONDITIONS [PDF]

open access: yes, 2012
Early colonization of crop roots by arbuscular mycorrhiza (AM) is considered beneficial but its importance likely depends on the possible stresses faced by the host plant. Manganese toxicity is one such stress that AM can alleviate.

Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

open access: yesNordic Journal of Botany, EarlyView.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, EarlyView.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...
