Ecology of native bees in North Taranaki, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2018
Studies are increasingly finding that native bees are important pollinators in many systems, in both natural and agricultural settings. With the possible loss of honey bees due to various reasons, it has become clear that relying on major pollinator for ...

Wild Bee Conservation within Urban Gardens and Nurseries: Effects of Local and Landscape Management [PDF]

open access: yes, 2019
Across urban environments, vegetated habitats provide refuge for biodiversity. Gardens (designed for food crop production) and nurseries (designed for ornamental plant production) are both urban agricultural habitats characterized by high plant species ...

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 ...

Providing foraging resources for solitary bees on farmland: current schemes for pollinators benefit a limited suite of species [PDF]

open access: yes, 2017
1. Changes in agricultural practice across Europe and North America have been associated with range contractions and a decline in the abundance of wild bees.

Flower‐Derived Environmental DNA Reveals Community Diversity, Species Abundances and Ecological Interactions in Bee Pollinators

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
We show that communities of wild bees can be accurately characterized by flower‐derived environmental DNA. eDNA based monitoring recovers relative abundances of individual bee species and provides information on the ecological specificity of different bees on individual plants.

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

Microbial Evolution in Allodapine Bees: Perspectives From Trophallactic, Socially Plastic Pollinators

open access: yesEvolutionary Applications, Volume 18, Issue 7, July 2025.
ABSTRACT This review seeks a deeper functional understanding of wild bee microbiomes by focusing on a tribe of bees where natural history and behavioral ecology are well known but investigations of microbiology are just beginning. Opportunities to improve our future knowledge of pathogens to insect pollinators are explored—which have broad ...

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.

Morphological trends in the molars of fossil rodents from the Fayum Depression, Egypt [PDF]

open access: yes, 2007
While many of the mammalian taxa from the Fayum of Egypt, such as the primates and hyraxes, have been well-studied, little is known about the rodents. Species described to date have all been referred to the endemic family Phiomyidae. Many rodent species

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 ...
