Phenotypic selection on nectar amino acid composition in the Lepidoptera pollinated orchid species Gymnadenia conopsea

open access: yes, 2015
© 2014 The Authors. Plant-pollinator interactions are potential drivers of evolution in floral traits. Because nectar chemical composition is known to mediate both plant-pollinator interactions and plant reproductive success, it can be expected that ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Assessment of Floral Nectar and Amino Acid Yield in Eight Landscape Trees for Enhanced Pollinator Food Resources in Urban Forests

open access: yesPlants
Urban environments pose challenges for pollinators due to habitat loss and limited floral resources. However, green infrastructure, particularly street and ornamental trees, can play a critical role in supporting urban pollinator communities.

Seasonal Difference of Gut Microbiota at a Stopover Site in Five Passerines of Different Migratory Behavior

open access: yesIntegrative Zoology, EarlyView.
Seasonal variation significantly reshaped gut microbiota composition in migratory passerine species, whereas the resident species Suthora webbiana showed no clear seasonal shift. Species with similar migratory behaviors exhibited consistent seasonal patterns in their core gut microbiota.

Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Undoing composition? [PDF]

open access: yes, 2012
This piece is a contribution to a symposium on the relationship of literacy studies to composition studies. Three central foci of literacy studies have direct implications for composition studies: the shift from canonical to everyday texts, practices and

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

open access: yesAgricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive
