Long-term data on species dynamics are scarce, limiting our understanding of biodiversity changes. We analysed over 17,500 museum records of 342 wild bee species collected between 1910 and 2021 at eight sites. Linking temporal distributions to land-use and climatic data, we show that continuous species turnover has reduced diversity over time. Earl...

Most terrestrial ecosystems are shaped by the pollination service provided by insects, foremost bees. As bees are also important pollinators of crop plants, they are key for both the pollination of wild plants and for agricultural production. Meadows and semi-natural habitats (SNHs) are important habitats for bees. However, there is limited knowled...

Cold-adapted species endangered by global change are crucial cases for understanding range dynamics and its interface with conservation. In view of climate change and their sensitivity, Alpine insects should modify their distribution by reducing ranges, while being unable of sufficient displacements and mostly moving uphill. To test these hypothese...

Die aktuelle Checkliste der Bienen (Anthophila) Kärntens umfasst 429 Arten aus 6 Familien. Das Artenspektrum ist als mäßig gut bekannt anzusehen, der faunistische Durchforschungsgrad der letzten Jahrzehnte ist als unzureichend einzustufen. Die vorliegende Rote Liste gefährdeter Bienen Kärntens ist die zweite landesweite Darstellung der Gefährdungs...

Simple Summary Climate warming affects diversity, community composition, and spatial distribution of several plant and invertebrate species. Bumblebees in alpine ecosystems are particularly exposed to climate change due to even stronger warming compared to the global mean. To investigate the effects of climate warming, we sampled bumblebees along m...

In this paper 13 species of wild bees are recorded for the first time for the federal state of Salzburg, Austria, among them the invasive species Megachile sculpturalis and Bombus semenoviellus. This bumblebee species was so far recorded only once in Austria. New locations of another three rare species are published. Actually, 333 species of bees a...

Commented list of bee species (Hymenoptera: Apidae) recorded from Vienna, 2 nd edition.-Due to the diverse structure of its natural environments and their integrity in the city's outskirts, Vienna possesses a very high biodiversity compared to other Central European cities. Bees (Apidae s. l.) play an important role in Europe's ecosystems as pollin...

Aim Global warming is assumed to restructure mountain insect communities in space and time. Theory and observations along climate gradients predict that insect abundance and richness, especially of small‐bodied species, will increase with increasing temperature. However, the specific responses of single species to rising temperatures, such as spati...

The flower bee Anthophora crinipes SMITH, 1854 is expanding its range from Austria to Bavaria. After the first reliable record for Germany was made near Passau in 2019, the second record for Germany is documented in southeastern Bavaria. Several females were caught in Laufen (Salzach) in June 2021.

Entomophilous plants have evolved colorful floral displays to attract flower visitors to achieve pollination. Although many insects possess innate preferences for certain colors, the underlying proximate and ultimate causes for this behavior are still not well understood. It has been hypothesized that the floral rewards, e.g., sugar content, of pla...

Red Lists are important tools for nature conservation, especially if up-to-date information on the threat status of species is available. Due to the high diversity of habitats (e.g., elevation and climatic zones) within a small area, Austria’s wild bee diversity is high compared to other Central European countries, with currently 702 species listed...

This study reports on a survey of the wild bee fauna (Apidae s.l.) in the Umbal and Virgen Valleys, East Tyrol, during 17–23 July 2020. Eighty-nine species were registered. Hylaeus (Hylaeus) annulatus (linnAeuS, 1758) and Osmia (Melanosmia) alticola BenoiSt, 1922 are recorded from East Tyrol for the first time.

Species range expansions are crucial for understanding niche formation and the interaction with the environment. Here, we studied the bumblebee Bombus haematurus Kriechbaumer, 1870, a species historically distributed from northern Serbia through northern Iran which has very recently started expanding north‐westwards into Central Europe without huma...

Range expansions of naturally spreading species are crucial for understanding how species interact with the environment and build their niche. Here, we studied the bumblebee Bombus haematurus Kriechbaumer, 1870, a species historically distributed in the eastern Mediterranean area which has very recently started expanding northwards into Central Eur...

The East Himalaya is one of the world’s most biodiverse ecosystems. However, very little is known about the abundance and distribution of many plant and animal taxa in this region. Bumble bees are a group of cold-adapted and high elevation insects that fulfil an important ecological and economical function as pollinators of wild and agricultural fl...

The East Himalaya is one of the world's most biodiverse ecosystems. Yet, very little is known about the abundance and distribution of many plant and animal taxa in this region. Bumble bees are a group of cold-adapted and high altitude insects that fulfill an important ecological and economical function as pollinators of wild and agricultural flower...

Insect pollinators are a key component of biodiversity; they also play a major role in the reproduction of many species of wild plants and crops. It is widely acknowledged that insect pollinators are threatened by many environmental pressures, mostly of anthropogenic nature. Their decline is a global phenomenon. A better understanding of their dist...

The bee fauna of Salzburg is poorly documented (Schwarz et al. 1996, Gusenleitner et al. 2012). In the last years, we found 16 bee species not known from this federal state. The occurrence of three species with hitherto uncertain data basis was proven. Additionally, new distribution data of two further rare species are published. At the moment 308...

Bumblebees in Europe have been in steady decline since the 1900s. This decline is expected to continue with climate change as the main driver. However, at the local scale, land use and land cover (LULC) change strongly affects the occurrence of bumblebees. At present, LULC change is rarely included in models of future distributions of species. This...

Climate change is threatening species and habitats. Altitudinal shifts uphill and negative population trends are commonly observed in altitude-related taxa. The bumblebee Bombus alpinus (Linnaeus, 1758) has a disjoint distribution restricted to Fennoscandia and the Alps, and is considered threatened. We studied the ecology and distribution of B. al...

The Bombus lucorum complex represents a group of three distinct but cryptic bumblebee species in Europe. With the advent of DNA-based identification methods, their species status was confirmed and the use of COI barcoding proved to be an especially useful tool for species identification within the group. Meanwhile, the identification based on morph...

Farmland is a major land cover type in Europe and Africa and provides habitat for numerous species. The severe decline in farmland biodiversity of the last decades has been attributed to changes in farming practices, and organic and low-input farming are assumed to mitigate detrimental effects of agricultural intensification on biodiversity. Since...

Non-rewarding orchids rely on various ruses to attract their pollinators. One of the most common is for them to resemble flowers sought by insects as food sources. This can range from generalized food deception to the mimicry of specific sympatric food plants. We investigated the basis of pollinator deception in the European food-deceptive orchid T...

Due to the diverse structure of its natural environments and their integrity in the city’s outskirts (Lainzer Tiergarten, Lobau etc.), Vienna possesses a very high biodiversity com- pared to other Central European cities. Bees (Apidae) play an important role in Europe’s ecosystems as pollinators of owering plants and are one of the most speciose fa...

The authors gathered all the distribution data on European bumblebees (Bombus). The resulting data base includes information on nearly 900.000 specimens from all parts of the West Palaearctic. There are 77 bumblebee species in the studied region, including twelve social obligate parasites (ten from subg. Psithyrus, and two others). Species have bee...

Bumblebees are among the most important pollinators in the high mountain regions. Within the Bombus lucorum-complex, at least two cryptic species (Bombus lucorum, B. cryptarum) inhabit the Austrian Alps, a third one (B. magnus) cannot be excluded to occur. Recent molecular studies indicate that colour-patterns used for identification do not corresp...

In den Jahren 2005, 2007 und 2008 wurden die Aculeaten Hymenopteren (ohne Ameisen) des Nationalparks Thayatal und seiner unmittelbaren Umgebung erforscht. 190 Bienenarten konnten nachgewiesen werden, das sind 28,7% aller österreichi-schen Arten. Auf das Vorkommen weiterer Bienenarten kann mit hoher Wahrscheinlichkeit geschlossen werden. Weiters wur...

In alpine habitats, butterfl ies constitute one of the major pollinator groups, yet little is known about their foraging behavior and fl ower preferences. At three experimental sites located between 1750 m and 2350 m asl in the Hohe Tauern National Park, Austria, fl ower visitation behavior of butterfl ies was observed between spring and late summe...

A b s t r a c t : Influence of honey-bees on nectar supply and native flower visitors. The effects of honey bees on other flower visitors is often discussed but not easy to proof. Effects of the presence of honeybees were studied in a naturally honeybee-free valley of the Hohe Tauern (Austrian Alps). Two honeybee hives were placed at 1650m asl thro...
