Human driven environmental changes increase the concentrations of polluting reactive
compounds in the troposphere, such as ozone and nitrogen oxides. These changes lead to …

As an early-industrialising northern European country, Belgium has a comparatively
wellstudied insect fauna. Despite this, many challenging insect groups have lacked …

We revise the Alpine bee taxa related to Andrena bicolor (Fabricius, 1775), including A.
montana Warncke, 1973 and A. allosa Warncke, 1975, the status of which has remained …

Mutualistic bee–plant interaction networks are a vital part of terrestrial ecosystems. They
frequently arise through co-evolutionary processes, which match the traits of both partners …

Many insects have a crucial role as pollinators in both natural ecosystems and agricultural
systems. Reports of declining pollinator populations highlight the question how we can …

Red Lists are widely used as an indicator of the status and trends of biodiversity and are
often used in directing conservation efforts. However, it is unclear whether species with a …

Agricultural intensification and loss of semi-natural grassland have contributed to
biodiversity decline, including pollinator species, in pastures around the world. To reverse …

Abstract Osmia (Allosmia) and O.(Neosmia) are two closely related Palaearctic osmiine bee
subgenera (Megachilidae, Megachilinae, Osmiini) comprising eleven and ten species …

Studies have found that biotic information can play an important role in shaping the
distribution of species even at large scales. However, results from species distribution …

Several population genetic studies investigated the extent of gene flow and population
connectivity in bumblebees. In general, no restriction in gene flow is considered for …
