Dominance of Ricinus communis in the Semi‐Arid Region Mediated by Allelopathy

open access: yesWeed Research, Volume 66, Issue 2, March/April 2026.
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.

Relative pollen productivity estimates from India: A step towards quantitative reconstruction of past plant abundance

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
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 ...

Caracterização morfológica de espécies de trapoeraba (Commelina spp.) utilizando a análise multivariada Morphological characterization of wandering-jew species (Commelina spp.) using multivariate analysis

open access: yesPlanta Daninha, 2007
As espécies Commelina benghalensis, C. villosa, C. diffusa e C. erecta são conhecidas como trapoeraba e, freqüentemente, são confundidas entre si, dificultando o controle químico, o que pode provocar prejuízos econômicos e danos ambientais.

From Local Biodiversity to Global Food Security: Antioxidant Evidence of Unconventional Edible Plants (2020–2025)

open access: yesJournal of Food Process Engineering, Volume 49, Issue 2, February 2026.
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 ...

Biology and Management of Dayflowers (Commelina spp.) in Ornamental Plant Production and Landscapes in Florida

open access: yesEDIS
Several native and non-native dayflower (Commelina) species can be found in Florida landscapes and production nurseries. Two of the most widely distributed species include the native whitemouth dayflower (Commelina erecta) and the non-native spreading ...

Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1253-1267, February 2026.
Summary Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptors signals the availability of sunlight for photosynthesis.

Habitat Structure Shapes Mollusc Assemblages in an Urban Semiarid River: Implications for Conservation and Public Health

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
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

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
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.
