Extrafloral nectaries on Cenchrus americanus (L.) Morrone

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Pearl millet, Cenchrus americanus (L.) Morrone (formerly Pennisetum glaucum L.), used for food and feed, has pollen that attracts multiple insect species. In 2023, honey bees and wasps were observed foraging on or below the auricles of pearl millet in a Georgia field.

Presumed domatia are actually extrafloral nectaries on leaves of Anacardium humile (Anacardiaceae)

Rodriguésia
Presumed domatia are actually extrafloral nectaries on leaves ofAnacardium humile (Anacardiaceae), a species from the Brazilian savannah, is associated with foraging ants, which leads to the description of the structure of its leaves as domatia. However,

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.

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 ...

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.

Diel activity patterns of a canopy-inhibiting beetle community (Coleoptera) in a Neotropical rainforest

Frontiers in Forests and Global Change
Diel activity is one main feature of animal‘s behavior and is often an intrinsic trait characterizing distinct taxonomic groups. Abiotic conditions such as temperature may influence the diel activity patterns of arthropod communities associated with a ...

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Estruturas secretoras em cipó-d'alho (Mansoa standleyi (Steyerm.) A. H. Gentry, Bignoniaceae): ocorrência e morfologia Secretory structures in cipó-d'alho (Mansoa standleyi (Steyerm.) A. H. Gentry, Bignoniaceae): occurrence and morphology

Acta Amazonica, 2012
Espécies de Mansoa são denominadas de "cipó-d'alho", por exalarem odor de alho das partes vegetativas e reprodutivas. Contudo, dados sobre morfologia e distribuição das estruturas secretoras presentes em Mansoa são escassos e ausentes para M.
