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.

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.

A változó mezőgazdaság hatása termesztett növényeink természetes megporzó rovarnépességeire = Impact of changing agriculture on the native pollinating insect assemblages of cultivated crop plants [PDF]

open access: yes, 2008
Négy egymás utáni évben a lucerna, vöröshere, bükköny, napraforgó, vöröshagyma és gyümölcsfajok (alma, meggy) megporzó rovarnépességeit vizsgáltuk. Lucernásokban 113 vadméh fajt mutattunk ki. A lucernások Apoidea megporzó népessége átstrukturálódott.
