Overall, 9.2% of bees are considered threatened in all of Europe, while at the EU 27 level, 9.1% are threatened with extinction. A further 5.2% and 5.4% of bees are considered Near Threatened in Europe and the EU 27, respectively (101 species at both levels). However, for 1,101 species (56.7%) in Europe and 1,048 species (55.6%) at the EU 27, there...

Dasypoda bees are host-specialized solitary species distributed in the Palaearctic Region. In the framework of a global revision of this genus, comprehensive descriptions of three rare species (D. tibialis Morawitz, D. vulpecula Lebedev and D. iberica Warncke) are presented. The detailed morphology of the D. tibialis male and both sexes of D. vulpe...

Dasypoda morawitzi Radchenko, 2016, a cryptic bee species separated from D. hirtipes (Fabricius, 1793) and recently described from Eastern Europe, Western Kazakhstan, Caucasus and Turkey, is for the first time recorded from Czech Republic, Romania and Spain. We also provide additional new records for several other countries. An additional comparati...

Wild bees represent a global group of highly diversified insect pollinators, nowadays concerningly well known for their widespread observed patterns of decline. Amongst them is the genus Dasypoda, a widespread Palearctic clade of solitary bees generally poorly represented in entomological collections. Among the 39 accepted species of the genus, 35...

All three hitherto described species of the Palearctic subgenus Andrena (Longandrena Osytshnjuk, 1993), are revised and redescribed. This subgenus is characterized by an unusually long glossa, a rare character among short-tongued bees. A revised diagnosis of this subgenus is given. A key to the species of A. (Longandrena) is provided, and all diagn...

Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental levels is needed to implement efficient conservation actions, but this knowledge is still fragmented and/or difficult to access. As a...

At a time when nature conservation has become essential to ensure the long-term sustainability of our environment, it is widely acknowledged that conservation actions must be implemented within a solid taxonomic framework. In preparation for the upcoming update of the IUCN Red List, we here update the European checklist of the wild bees (sensu the...

With its diverse range of climates and landscapes, the Middle East offers a remarkable area for the study of bee taxonomy and biogeography. In this work, a new species of pantaloon bee (Dasypoda delectabilis Ghisbain & Michez sp. nov.) is described from a single male collected in southeastern Iran. Although the new species shows affinities with the...

Enzymatic hydrolysis is an environmentally friendly technology to produce sugars from pretreated biomass. Here, we show that the new Il-11 Irpex lacteus strain can synthesize cellulases in a high quantity. The peptone and filter paper contained in the medium significantly enhanced activity of endo-1,4-β-D-glucanases (app. 50 IU/mL) and total cellul...

Within collected specimens, 12 species were new records for Iranian fauna. The subgenus Tarsandrena was also reported for the first time from the country. Taking into account the new records, the number of all bee s...

Anthropogenic drivers of bumblebee population decline are well-established, particularly in Europe and North America. Agriculturalizsation is associated with a loss of nesting sites, habitat fragmentation, agrochemical toxicity and nutritional stress; climate change is affecting population distribution, phenology, and voltinism, among other traits....

Human-induced environmental impacts on wildlife are widespread, causing major biodiversity losses. One major threat is agricultural intensification, typically characterised by large areas of monoculture, mechanical tillage, and the use of agrochemicals. Intensification leads to the fragmentation and loss of natural habitats, native vegetation, and...

Some flying beetles have peculiar functional properties of their elytra, if compared with the vast majority of beetles. A “typical” beetle covers its pterothorax and the abdomen from above with closed elytra and links closed elytra together along the sutural edges. In the open state during flight, the sutural edges diverge much more than by 90°. Se...

The IUCN Red List of Threatened Species

Bombus alpinus has most recently been assessed for The IUCN Red List of Threatened Species in 2014. Bombus alpinus is listed as Vulnerable under criteria B2b(i,ii,iii,v)c(iv).

Loss of the flight ability and wing reduction has been reported for many taxa of Coleoptera. If elytra are closed, their roots are clenched between the tergum and the pleuron, forces applied to the elytra can not be transmitted to the field of campaniform sensilla situated on the root. That is why it is plausible to assume that the field becomes re...
