Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

1170. Allium kollmannianum Brullo, Pavone & Salmeri

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

1173. Ipomoea pandurata (L.) G. Mey

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Ipomoea pandurata is a Morning Glory from North America which develops a large storage root. There is much uncertainty about its discovery before its formal description in the middle of the 18th century. Originally described as a Convolvulus, almost a hundred years passed before its recognition as a species of Ipomoea.

Does the Floral Nectary in Dracocephalum moldavica L. Produce Nectar and Essential Oil? Structure and Histochemistry of the Nectary

open access: yesBiology, 2022
Dracocephalum moldavica is an aromatic plant with a lemon scent and versatile use. Its flowers produce large amounts of nectar, which is collected by bees and bumblebees. The aim of the study was to investigate the structure of the floral nectary in this

Nectary Specification in Petunia and Arabidopsis [PDF]

open access: yesThe Plant Cell, 2018
Studies of flower development have lots of information about petals, carpels, and stamens, but let’s not forget the birds and the bees—and the flies and moths—and what draws pollinators to insect-pollinated flowers, including flower color, shape, and rewards that provide energy. For example,

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

open access: yesInsect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Species loss can restructure plant–pollinator interactions, but the functional consequences of altered interactions remain unclear. Using camera observations and experimental manipulations in Hawaiian lobelioids, we show that nectarivorous birds differ in whether visits result in pollen contact or nectar robbing, with robbing altering nectar dynamics ...
