Foraging energetics reveals late‐summer challenges for pollinators across two British cities

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

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

Entomologia 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.

Brazilian ground pearl damaging blackberry, raspberry and blueberry in Brazil Pérola-da-terra causando danos em amoreira-preta, framboeseira e mirtileiro no Brasil

Ciência Rural, 2012
The Brazilian ground pearl, Eurhizococcus brasiliensis (Wille, 1922) (Hemiptera: Margarodidae), is a subterranean, polyphagous scale insect native of Southern Brazil that feeds on a variety of different vineyard plant species (Vitis spp.). In this study,

Honeybees directly outcompete other flower visitors through interference competition on shared resource

Ecological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...
