Planting native wildflowers improves vacant land as bee habitat in a post‐industrial city

open access: yesEcological Entomology, Volume 50, Issue 3, Page 538-551, June 2025.
Greening with native wildflowers in urban vacant land (pocket prairies) increases bee abundance and species richness in the post‐industrial city of Cleveland, Ohio, USA. Pocket prairies supported a similar bee abundance to Metropark grasslands in the surrounding landscape, but Metropark grasslands supported significantly higher bee diversity and ...

Host identity, nest quality, and parasitism strategy: influences on body size variation in parasitoid bees and wasps

open access: yesOikos, Volume 2025, Issue 6, June 2025.
Body size determines mobility and fitness across taxa in various ways. Yet, drivers of body size in higher trophic invertebrates, especially parasitoids, including intra‐ and interspecific variations, are poorly understood due to complex interactions between parasitoid behaviour, the environment and their hosts.

Description of mature larvae and ecological notes on Gasteruption Latreille (Hymenoptera, Evanioidea, Gasteruptiidae) parasitizing hymenopterans nesting in reed galls

open access: yesJournal of Hymenoptera Research, 2018
Wasps of the genus Gasteruption are predator-inquilines of bees nesting in cavities in wood, stems, galls, and vertical soil surfaces. During studies of hymenopterans associated with reed galls caused by flies of the genus Lipara we recorded three ...

Diet characterisation of solitary bees on farmland: dietary specialisation predicts rarity [PDF]

open access: yes, 2016
Changes in agricultural practice across Europe and North America have been associated with declines in wild bee populations. Bee diet breadth has been associated with sensitivity to agricultural intensification, but much of this analysis has been ...

Looking to the past to inform the future: What eDNA from herbarium specimens can tell us about plant–animal interactions

open access: yesApplications in Plant Sciences, Volume 13, Issue 2, March-April 2025.
Abstract Premise The importance of natural history collections in modern ecological and genetic research cannot be overstated. Herbarium specimens provide historical information that can be used to investigate community ecology, phenology, and population genetics. In this study, environmental DNA (eDNA) metabarcoding and next‐generation sequencing were

Preliminary assessment of cavity‐nesting Hymenopterans in a low‐intensity agricultural landscape in Transylvania

open access: yesEcology and Evolution, 2021
In this study, our aim was to assess several traits of cavity‐nesting Hymenopteran taxa in a low‐intensity agricultural landscape in Transylvania. The study took place between May and August 2018 at eight study sites in the hilly mountainous central part

Mitochondrial heteroplasmy and DNA barcoding in Hawaiian Hylaeus (Nesoprosopis) bees (Hymenoptera: Colletidae)

open access: yesBMC Evolutionary Biology, 2010
Background The past several years have seen a flurry of papers seeking to clarify the utility and limits of DNA barcoding, particularly in areas such as species discovery and paralogy due to nuclear pseudogenes.
