Bees are associated with a remarkable diversity of microorganisms, including unicellular parasites, bacteria, fungi, and viruses. The application of next-generation sequencing approaches enables the identification of this rich species composition as well

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

Separating Sampling Bias From Abundance Shows That Different Methods Catch Different Wild Bees
Comparing community sampling methods' relative taxonomic biases is critical to interpreting the data they collect, but measuring bias explicitly is difficult when methods also produce different sample sizes. Here, we control for absolute abundance while comparing sample composition and richness of three common methods for sampling wild bee communities.

Biological Flora of Britain and Ireland: Geranium sylvaticum*
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Wege der Mikroevolution und Artbildung bei Bienen (Apoidea, Hymenoptera): Populationsgenetische und empirische Aspekte [PDF]
Bees are haplodiploid organisms: haploid males develop from unfertilized eggs, diploid females from fertilized eggs. Under haplodiploidy, deleterious mutations are effectively purged by purifying selection on haploid males.

ABSTRACT Fire is a major form of environmental disturbance, and in recent years, due to anthropogenic climate change and anthropogenic land management, we are seeing increases in the frequency and intensity of fires. With bees being an important, diverse group of pollinators that is facing declines globally, understanding how they respond to fires is ...

Reproductive biology of "Helianthemum apennium" (L.) Mill. and "H. caput-felis" Boiss. (Cistaceae) from Mallorca (Balearic Island, Spain) [PDF]
El estudio de la biología reproductiva de poblaciones naturales de Helianthemum apenninum y H. caput-felis en Mallorca ha demostrado que son básicamente entomófilos, aunque también producen numerosos frutos por auto-polinización. Las flores de H.

Mapping bee diversity with landscape‐level models to inform conservation
Native bee conservation is complicated by limited distribution data and life history knowledge. However, recent state‐wide pollinator surveys, combined with species distribution models that account for biased datasets and capture regional habitat associations, present a strong foundation for informing essential conservation action.
