Rote Liste der Bienen Baden-Württembergs

In der jüngsten Vergangenheit hat die Anwendung der inzwischen veralteten Liste zunehmend Probleme bereitet und zwar nicht nur im Zusammenhang mit der Begründung von Naturschutzmaßnahmen, sondern auch bei Bewertungen von Flächen z.B. im Rahmen von Umweltverträglichkeitsstudien und Eingriffsplanungen. Die Diskrepanz zwischen einer früheren Rote-Liste-Einstufung und der heutigen, auf erweiterten Erkenntnissen beruhenden Bewertung der Bestandssituation bestimmter Arten muss unweigerlich zu falschen Schlüssen hinsichtlich der Wertigkeit der zu beurteilenden Flächen führen (vgl. WESTRICH & SCHWENNINGER 1997). Es war deshalb sehr zu begrüßen, dass die Landesanstalt für Umweltschutz Karlsruhe eine Neubearbeitung ermöglicht hat. Dabei sollte gleichzeitig auch den zwischenzeitlich vom Bundesamt für Naturschutz modifizierten Gefährdungskategorien und -kriterien Rechnung getragen und die Fülle an neuen wissenschaftlichen Erkenntnissen integriert werden. Diese waren, soweit möglich, bereits in der Roten Liste der Bienen Deutschlands (WESTRICH et al. 1998) berücksichtigt worden. Da eine Rote Liste stets das im Bezugsraum nachgewiesene Artenspektrum zur Grundlage haben muss, war es erforderlich, auch die Faunenliste im Vorfeld zu aktualisieren, zumal seit dem Erscheinen des Grundlagenwerks zahlreiche Arten erstmals in Baden-Württemberg aufgefunden werden konnten

Andrena (Chlorandrena) harisi, a New Bee Species from Libya (Hymenoptera: Anthophila, Andrenidae)

Andrena (Chlorandrena) harisi n. sp. from Libya is described and illustrated. Characters for separation of this new species from similar Andrena (Chlorandrena) pyrrhula Pérez, 1895 are provided

Fig. 4. Favourite plants as pollen hosts. Scaled pollen scores for each of the identified 34 "high visitor richness" plant species (according to Fig. 3). The scaled pollen score for one plant species is the percentage of other plant species that are visited by a lower number of bee species, e.g. a scaled pollen score of 100 shows that all other plant species in the database were visited by a lower number of bee species. The maximum number of bee species visiting one plant species is 71 and the total number of plant species described in Westrich (2018) is 494. The average scaled pollen score of 50 is indicated by the dashed red line.Published as part of <i>Kuppler, Jonas, Neumüller, Ulrich, Mayr, Antonia Veronika, Hopfenmüller, Sebastian, Weiss, Karin, Prosi, Rainer, Schanowski, Arno, Schwenninger, Hans-Richard, Ayasse, Manfred & Burger, Hannah, 2023, Favourite plants of wild bees, pp. 103766 in Agriculture, Ecosystems & Environment 342</i> on page 6, DOI: 10.1016/j.agee.2022.108266, <a href="http://zenodo.org/record/10182940">http://zenodo.org/record/10182940</a&gt

Fig. 5 in Favourite plants of wild bees

Fig. 5. Favourite plants as hosts for polylectic, oligolectic and threatened species. Percentage of wild bee species visiting each of the identified 34 "high visitor richness" species (according to Fig. 3). 100% of observed bee species is the total number of polylectic, oligolectic and threated species that are included in the Wildbienen-Kataster dataset, which includes ~ 75% of all wild bee species in Germany (440 species in total, containing 87 oligolectic and 177 red-listed species). The percentage of wild bee species for plants that are not widespread in the study area, such as Chondrilla juncea or Ballota nigra, are underestimated.Published as part of <i>Kuppler, Jonas, Neumüller, Ulrich, Mayr, Antonia Veronika, Hopfenmüller, Sebastian, Weiss, Karin, Prosi, Rainer, Schanowski, Arno, Schwenninger, Hans-Richard, Ayasse, Manfred & Burger, Hannah, 2023, Favourite plants of wild bees, pp. 103766 in Agriculture, Ecosystems & Environment 342</i> on page 7, DOI: 10.1016/j.agee.2022.108266, <a href="http://zenodo.org/record/10182940">http://zenodo.org/record/10182940</a&gt

Fig. 3 in Favourite plants of wild bees

Fig. 3. Favourite plants of bees. Plant species are grouped into "high visitor richness", "medium visitor richness" and "low visitor richness" based on the bee visits observed in the BienABest-project. On each sampling date and each habitat and location, the plant species were ranked based on the increasing number of visiting bee species. Mean ranks ¯R i for each plant species during all months (yellow), during April and May (green), during June (blue) and during July and August (purple) are shown. As the BienABest dataset contains a high proportion of interactions of polylectic and common species (male and female individuals), we additionally highlighted the top plant species with the greatest number of visiting oligolectic (+, n = 18 plant species) and red listed wild bee species (*, n = 17 plant species) according to Wildbienen-Kataster dataset.Published as part of <i>Kuppler, Jonas, Neumüller, Ulrich, Mayr, Antonia Veronika, Hopfenmüller, Sebastian, Weiss, Karin, Prosi, Rainer, Schanowski, Arno, Schwenninger, Hans-Richard, Ayasse, Manfred & Burger, Hannah, 2023, Favourite plants of wild bees, pp. 103766 in Agriculture, Ecosystems & Environment 342</i> on page 5, DOI: 10.1016/j.agee.2022.108266, <a href="http://zenodo.org/record/10182940">http://zenodo.org/record/10182940</a&gt
