Effects of Time‐Since‐Fire on Ant Interactions With Nectar Resources in a Semi‐Arid Landscape

Austral Ecology, Volume 51, Issue 7, July 2026.
ABSTRACT Semi‐arid ecosystems are shaped by frequent wildfires, making the management of landscape disturbances a major conservation challenge in this region. Ant–plant nectar interactions, driven by mutualisms, contribute to ecosystem functioning and biodiversity, with interaction networks a poorly understood aspect of ecosystem recovery from ...

Dispersal and in Situ Speciation as Contributors to Plant Diversity in the Chocó Region: Insights From Inga Mill. (Leguminosae)

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim To investigate the historical processes underlying the assembly of the flora of the Chocó region, with a focus on the relative contributions of dispersal and in situ speciation. Using Inga (Leguminosae) as a model lineage, we evaluate the origin and diversification of species present in the Chocó.

Morphology, ontogeny and structure of the stipular nectaries in Caamembeca spectabilis (Polygalaceae) [PDF]

Acta Amazonica, 2016
Nodal glands are found in one third of the Polygalaceae genera and have valuable taxonomic, ecological and evolutionary significance. In Brazil, they occur in five of the eleven genera already registered.

Protocols for the development of the guidance on the risk assessment of PPP to non‐target arthropods, in‐soil organisms and non‐target terrestrial plants

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The present document defines the problem formulation, evidence needs and methodological approach agreed by the Environmental Risk Assessment Working Group and the EFSA Panel on Plant Protection Products and their Residues for the Tier 1 risk assessment of the terrestrial ecotoxicology guidance document.

Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.

Ants visit nectaries of Epidendrum denticulatum (Orchidaceae) in a Brazilian rainforest: effects on herbivory and pollination

Brazilian Journal of Biology
Epidendrum denticulatum (Orchidaceae) produces nectar on the petioles of buds, flowers, and fruits (extrafloral nectaries) but no nectar is found on its flowers, and it is probably a deceptive species.

Arthropods on native versus alien woody plants: Understanding variation across host plant taxonomy and geography

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Alien plants have generally been shown to support reduced arthropod abundance, biomass, and diversity compared to native plant species, but inferences have typically come from studies limited in taxonomic and geographic scope. Here, we make use of data from a unique citizen science project, Caterpillars Count!, that consists of nearly 70,000 ...

Chemical defense responses of upland cotton, Gossypium hirsutum L. to physical wounding

Plant Direct, 2019
Upland cotton (Gossypium hirsutum L.) produces terpenoid aldehydes (TAs) that protect the plant from microbial and insect infestations. Foliar TAs include plus (+)‐ and minus (−)‐gossypol, hemigossypolone, and heliocides.

Alternative flowering crops as potential food sources for beneficial arthropods

Journal für Kulturpflanzen, 2017
Various flowering crops (buckwheat, caraway, carrot, faba bean, flax, lupine, milk thistle, mustard, parsnip, phacelia) were evaluated for their suitability in providing nutritional resources for natural enemies and pollinators in small scale field ...

Plant species and floral traits shape arthropod communities in prairie plantings more than neonicotinoid contamination

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Agricultural practices are significant drivers of biodiversity loss, leading to reductions in ecological function and services across regions. To mitigate these effects, habitat restorations within agroecosystems have gained prominence as a strategy to enhance ecological stability and increase biodiversity.
