Flies and Flowers III: Ecology of foraging and pollination

Journal of Pollination Ecology, 2015
Diptera are important flower visitors and pollinators for many plant species and in a variety of habitats. Although Diptera are not as well studied as other groups of pollinators, there is a growing literature that we review here about the ecology of their foraging behaviour and their effectiveness as pollinators.

Distribution and pollination services of wild bees and hoverflies along an altitudinal gradient in mountain hay meadows

Ecology and Evolution, 2021
Extensively managed and flower‐rich mountain hay meadows, hotspots of Europe's biodiversity, are subject to environmental and climatic gradients linked to altitude.

Insect-flower interaction networks vary among endemic pollinator taxa over an elevation gradient.

PLoS ONE, 2018
Interaction networks are sensitive to elevation gradients through changes in local distribution of interacting partners. Here, we use plant-pollinator interaction network metrics to assess the effect of elevation on flowers and flower-visiting insect ...

Aneriophora aureorufa (Philippi, 1865) (Diptera: Syrphidae): a fly specialized in the pollination of Eucryphia cordifolia Cav. (Cunoniaceae R. Br.), an endemic species of South American temperate forest

Journal of Pollination Ecology, 2021
The order Diptera is the second most important group of pollinators worldwide. Many flies are considered generalist pollinators, but specialist flower flies’ associations are rare or uncommon.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Time since fire strongly and variously influences anthophilous insects in a fire‐prone landscape

Ecosphere, 2019
Drivers of species productivity and ecosystem function are of great ecological significance. In fire‐prone ecosystems, dispersion patterns of important pollinator species are driven by the various fire events over space and time.

PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

Advanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

Limitations of learning in the proboscis reflex of the flower visiting syrphid fly Eristalis tenax. [PDF]

PLoS ONE, 2018
Flower visiting Eristalis hoverflies feed on nectar and pollen and are known to rely on innate colour preferences. In addition to a preference for visiting yellow flowers, the flies possess an innate proboscis reflex elicited by chemical as well as ...
