Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, Volume 82, Issue 7, Page 6196-6206, July 2026.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Food Price Crises and the Insulation of Domestic Grain Markets

Agricultural Economics, Volume 57, Issue 4, July 2026.
ABSTRACT Studies that analyze the transmission of food prices from international to domestic markets for large sets of countries and products assume that price relationships are time‐invariant. However, studies that look in detail at individual countries and products show that countries respond to increasing international food prices with measures that

Contrasting Forest Trajectories Drive Changes in Bird Functional Traits

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim We investigated how bird functional diversity varies across forest habitat types with distinct successional trajectories, namely (1) natural succession forests, with naturally regenerating forests established on former grasslands; (2) secondary forest remnants resulting from deforestation; and (3) conserved forests.

Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.
