Dominance of Ricinus communis in the Semi‐Arid Region Mediated by Allelopathy
ABSTRACT The introduction of invasive alien species can adversely affect the functioning of natural ecosystems. Ricinus communis L., widely present in the Brazilian semi‐arid region, establishes itself in areas with native species, such as Handroanthus impetiginosus (Mart.

Stages of the study on the allelopathic potential of Calotropis procera (Aiton) W. T. Aiton. The image shows the collection of plant material, the decomposition of organic matter, the identification of bioactive compounds, and the effects on the germination of Handroanthus impetiginosus (Mart. ex DC.) Mattos.

Abstract Pollen records and models of pollen–vegetation relationships are required to reconstruct past plant abundances during the Holocene to answer specific questions on climate history, human impact, biodiversity, and their interactions. An important parameter for model applications is pollen productivity, estimated as relative pollen productivity ...

This scoping review (2020–2025) compiles validated evidence on the antioxidant potential of unconventional edible plants (PANCs). Thirty species showed high phenolic content and strong radical‐scavenging activity, reinforcing their role as natural antioxidants and sustainable alternatives to synthetic additives within biodiversity‐based food systems ...

ABSTRACT Fine‐scale environmental drivers shape freshwater mollusc assemblages in urban semiarid rivers. We examined how substrate composition and water chemistry influence mollusc richness and abundance along a polluted stretch of a river in the Brazilian semiarid region. Surveys at five sites recorded 2479 individuals.

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.
