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

The Distribution of Wild Bee Species Along a Latitudinal Gradient in Northern Europe Depends on Their Flower Preferences

open access: yesDiversity and Distributions, Volume 31, Issue 2, February 2025.
ABSTRACT Aim The functional diversity of bees contribute to the maintenance of plant biodiversity because different species of wild bees prefer and pollinate different plants. Many bees, in particular species with narrow flower preferences or specialised habitat requirements, are threatened by landscape homogenisation and climate change.

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.

Pollination ecology of New Zealand orchids : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University [PDF]

open access: yes, 2002
The New Zealand orchid flora comprises twenty-five genera and at least 100 species occurring throughout the country. Although the number of endemic species is high (69%) only four genera are endemic to New Zealand.

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 ...

Bee Diversity and Abundance During Peach Bloom in South Carolina, United States

open access: yesJournal of Applied Entomology, Volume 149, Issue 1, Page 23-35, February 2025.
ABSTRACT Peach (Prunus persica [L.] Batsch) is an important speciality fruit crop in the United States. Peach is self‐compatible, but bee pollination enhances fruit sets and diverse populations improve pollination efficiency. However, the bee diversity and abundance in peach orchards in South Carolina are unknown.

Variation in flower morphology associated with higher bee diversity in urban green spaces

open access: yesEcological Applications, Volume 35, Issue 1, January 2025.
Abstract Urbanization is a leading threat to biodiversity, but scientifically informed management of urban ecosystems can mitigate negative impacts. For wild bees, which are declining worldwide, careful consideration of flower choice in public and private green spaces could help preserve their diversity.

Contrasting effects of mass-flowering crops on bee pollination of hedge plants at different spatial and temporal scales [PDF]

open access: yes, 2013
Landscape-wide mass-flowering of oilseed rape (canola Brassica napus) can considerably affect wild bee communities and pollination success of wild plants.
