In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Zoophily and nectar-robbing by sunbirds in Gardenia latifolia Ait. (Rubiaceae)
Gardenia latifolia is a semi-deciduous tree species which blooms during the dry season. Its flowers are hermaphroditic, strongly fragrant, nectariferous, and specialized with a narrow corolla tube and concealed deep seated nectar. Thrips act as resident pollinators while bats and carpenter bees act as non-resident pollinators.

In southern England, Linaria vulgaris (common yellow toadflax) suffers from high rates of nectar robbery by bumblebees. In a wild population of L. vulgaris we found that 96 % of open flowers were robbed.

Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Rapid disruption of pollination function by the invasive plant Impatiens glandulifera
Invasion by Impatiens glandulifera rapidly disrupts pollination of the native plant Stachys sylvatica by altering pollen transport by shared bumblebee pollinators. A short‐term field introduction revealed a dramatic decline in conspecific pollen deposition within 4 days, showing that pollination function can collapse quickly following invasion, even ...

More than Moths: Flower Visitors of a Night-Blooming Plant in South Florida Pine Rocklands, USA
Plants whose flowers open at night but remain open during the day also attract diurnal flower visitors, potentially boosting their pollination rates and providing resources that can support diverse arthropod communities.

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

FIRST REPORT OF NECTAR ROBBING BY SWORD-BILLED HUMMINGBIRDS ENSIFERA ENSIFERA
A growing number of hummingbird species are known to practice nectar robbing. Hummingbirds that rob nectar tend to have short bills and to rob flowers with long, tubular corollas that prevent the birds from accessing nectar through its openings.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Increasing local floral richness can support pollination success of specialised plants in dense urban landscapes. However, a floral enrichment strategy alone is less effective for generalist plants, which are typically more abundant in plant communities.
