A new interpretation of the bee fossil Melitta willardi Cockerell (Hymenoptera, Melittidae) based on geometric morphometrics of the wing

open access: yesZooKeys, 2014
Although bees are one of the major lineages of pollinators and are today quite diverse, few well-preserved fossils are available from which to establish the tempo of their diversification/extinction since the Early Cretaceous.

Agricultural intensification indirectly reshapes bee–plant interaction networks through shifts in bee functional traits

open access: yesEcological Applications, Volume 35, Issue 6, September 2025.
Abstract High‐intensity farming can lead to non‐random local extinctions and functional filtering of pollinating insect assemblages, disproportionately harming species with certain traits. This process can ultimately reshape pollinator–plant interaction networks in predictable, consistent manners, although this pathway remains largely unexplored. Here,

Assessing wild bee fauna (Hymenoptera: Apoidea: Anthophila) in Calabria (southern Italy)

open access: yesThe European Zoological Journal
The ecological importance of wild bees as pollinators has become more widely recognized in recent years. However, knowledge regarding their diversity and distribution in numerous regions of Italy remains deficient in comparison to other Mediterranean ...

Structure of Bee Communities in Marginal Lands of the Puget Sound, USA

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We surveyed wild bee communities in marginal lands of the Puget Sound, USA. Bee communities were highly diverse and stable across seasons, but were variable within seasons. ABSTRACT Wild bee communities in urban ecosystems are often challenged by habitat fragmentation and low floral diversity.

The Importance of Bees for Eggplant Cultivations (Hymenoptera: Apidae, Andrenidae, Halictidae)

open access: yesSociobiology, 2014
The increasing demand for food and the “Pollination crisis” have emphasized the importance of better understanding the potential of different wild bee species for pollinating crops. The aim of this study was to investigate how dependent Solanum melongena

KUM ARILARI (Hymenoptera, Apoidea, Andrenidae)

open access: yesUludağ Arıcılık Dergisi, 2017
Yaban arıları, çok sayıda yabani ve kültür bitkisinin tozlaşmasını sağlaması dolayısıyla ekolojik ve ekonomik öneme sahiptir. Bu nedenle bu canlılar için “temel taşı” türler terimi kullanılır. Andrena Fabricius, 1775 cinsi yaban arıları genel olarak kum arıları olarak bilinir.

Seed Production and Pollinator Dependence in Native Wildflowers: Guiding Species Selection for Conservation Plantings

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated the pollination biology of eight native wildflower species in the southeastern U.S. to assess their dependence on insect pollinators and potential for self‐pollination. Most species showed significantly higher seed production and weight when open‐pollinated, indicating strong pollinator dependence, though some could reproduce without ...

Monitoramento de abelhas silvestres (Hymenoptera: Apoidea) em SAFs com dendê (Elaeis guineensis Jacq.) no município de Tomé-Açu, PA. [PDF]

open access: yes, 2011
Dentre as oleaginosas cultivadas no Brasil, o dendezeiro (Elaeis guineensis Jacq.) é a que mais produz óleo por unidade de área. A forma tradicional de cultivo do dendezeiro é o monocultivo, porém na Amazônia os Sistemas Agroflorestais (SAFs) são opções ...
