Zusammenfassung Im Osten und Nordosten Brandenburgs wurden in verschiedenen Gewässertypen neotene Teichmolche (Lissotriton vulgaris) beobachtet. Neben typischen Habitaten, wie einem ehemaligen Schwimmbecken und einem Feuerlöschteich, traten hierbei auch Kleingewässer der intensiv genutzten Agrarlandschaft in Erscheinung. Im Fall des Vorkommens in...

Die Südliche Eichenschrecke (Meconema meridionale) wurde nach einem Erstnachweis für Berlin im Jahr 2007 (SCZEPANSKI, 2008) im Jahr 2013 auch erstmals im Eberswalder Stadtteil Finow nachgewiesen. Seit dieser Zeit erfolgten sukzessive weitere Nachweise in anderen Stadtteilen. Dies gab den Anlass zu umfangreicheren, systematischen Untersuchungen. Daz...

New records of Epitheca bimaculata in western Brandenburg and Saxony-Anhalt (Odona-ta: Corduliidae)-After initial accidental detections in 2020 and 2021, Epitheca bimacula ta was detected in eight waterbodies in western Brandenburg and one in the district of Wit-tenberg (Saxony-Anhalt) by 2024. Four further occurrences in the Brandenburg districts...

Investigations on the impact of the environmental disaster in the river Oder in midsummer 2022 on the stream dragonfly community with special consideration of Clubtails (Gomphidae)-In August 2022, an environmental catastrophe in the river Oder led to a mass die-off of fish, mussels, and aquatic snails. High electrolyte concentrations from wastewate...

Reproduction records of Onychogomphus forcipatus forcipatus (Linnaeus, 1758) in the River Odra-Between June and July 2023, exuviae of Onychogomphus forcipatus forci-patus were found at different river sections of the River Odra in Brandenburg during a gomphid monitoring. This is the first published evidence of reproduction of this species in a lowl...

Die Mehrheit der letzten Jahre war durch Niederschlagsdefizite und sommerliche Hitzeperioden gekennzeichnet. Dies führte in vielen Regionen Brandenburgs zu einer zu frühzeitigen oder dauerhaften Austrocknung zahlreicher Kleingewässer und damit zu mehrjährigen Reproduktionsausfällen von Amphibien (z.B. SCHÖNBRODT & FISCHER 2021). Zur Sicherstellung...

Climate change is affecting the few remaining mires that are still accumulating peat. The question thus arising is this: To what extent can the resilience of these autochthonous ecosystems, in all their diversity, be enhanced? For this purpose, long-term observation series of mostly undisturbed peatlands in the Schorfheide-Chorin Biosphere Reserve...

In diesem Beitrag wird auf das Auftreten, die Abundanz, Verbreitung und Dynamik der beiden wärmeliebenden Heuschreckenarten Südliche Grille (Eumodicogryllus bordigalensis; Gryllidae) und Südliche Eichenschrecke (Meconema meridionale; Tettigoniidae) in der nordostdeutschen Stadt Eberswalde eingegangen. Für die Südliche Grille sind mittlerweile in zw...

First records of the Verge Cricket Eumodicogryllus bordigalensis (Latreille, 1804) in Brandenburg/ Germany. The first specimens of the Verge Cricket for Brandenburg were found in 2017 at the railway station of Angermünde and in 2018 at the railway station in Eberswalde. The two populations are the northernmost records for the species both for G...

We provide a report on the Orthoptera observations submitted to the online recording platform Heuschrecken.observation.org in 2021. A total of 14,074 Orthoptera observations were submitted by 1,510 recorders. In addition to the frequent use of the apps "ObsMapp" and "iObs", the app "ObsIdentify" has increasingly been used by citizen scientists. Two...

Status, recent population development and distribution of Aeshna affinis in Brandenburg, Germany (Odonata: Aeshnidae)-Presence of A. affinis was confirmed at 147 different sites in the German federal state of Brandenburg, including two sites in Berlin. From a total number of 266 observations, 264 were made in the period between 1992 and 2005. In 20...

Univoltine development of Leucorrhinia pectoralis and Brachytron pratense in a small water body in northeastern Brandenburg, Germany (Odonata: Libellulidae, Aeshnidae)-In a kettle hole near Brodowin, Brandenburg, in the dry and warm summer of 2001, the water body was observed to dry up completely for almost five months. Regular measurements of wate...

First record of Ceriagrion tenellum in Brandenburg (Odonata: Coenagrionidae)-In 2008 C. tenellum was recorded for the first time in Brandenburg, northeastern Ger-many. The circumstances of the record-a single male only-and the water body are briefly described. The species, which has chiefly an Atlantic and western Mediterranean distribution, benefi...

Reproduction evidence for Crocothemis erythraea and records of Aeshna affinis in the valley of River Oder, southeastern Brandenburg, Germany-In two ponds of a gravel pit complex near Eisenhüttenstadt the reproduction of Crocothemis erythraea was proved in 2004. A total of 17 exuviae were collected. In the closer surroundings of the waters imagines...

Predation is a key driver of phenotypic diversification with prey having evolved sets of correlated anti-predator traits. Changes in anti-predator traits can be studied on an evolutionary as well as on a developmental timescale. Using a common garden setup, we studied inter- and intraspecific correlations of behavioural and morphological defences i...

While much of global biodiversity is undoubtedly under threat, the responses of ecological communities to changing climate, land use intensification, and long-term changes in both taxonomic and functional diversity over time, has still not been fully explored for many taxonomic groups, especially invertebrates. We compiled time series of ground bee...

Nectar plants and other food sources as well as larval host plants of butterflies in the federal German states Brandenburg and Berlin (Lepidoptera: Rhopalocera et Hesperiidae) A first overall presentation on feeding ecology of butterflies will be given for the federal German states Brandenburg and Berlin. These results base on observation data by m...

Noch immer zählt die Beweidung forstlich genutzter Flächen in Deutschland zu den außergewöhnlichen Managementmaßnahmen des Naturschutzes. Am Beispiel der Landschaft um Hobrechtsfelde am nördlichen Berliner Stadtrand wird gezeigt, wie im Naturpark Barnim mittels extensiver Ganzjahresbeweidung auf mehr als 800 ha Fläche der halboffene Charakter diese...

Red List of dragonflies (Odonata) of the state Brandenburg (Germany), version 2016

Dragonfly research in the West Balkans experienced significant boost in recent years, also due to the establishment of the Balkan OdonatOlogical Meetings (BOOM) in 2011. The main goal of BOOM is to contribute to research and protection of dragonflies of the Balkan Peninsula. This paper presents the faunistic results of the 5 th BOOM, held in Republ...

Comparative adult morphology of Coenagrion lunulatum, C. pulchellum, and C. puella in a syntopic situation (Odonata: Coenagrionidae) – Interspecific competition among odonate species for food, mating partner etc. is a common phenomenon. Because morphology mediates species' behaviour and microhabitat use, competition is expected to increase with spe...

Azanus ubaldus (Cramer, 1782), a palaeotropical species which was previously known in the Canary Islands from a single location on Gran Canaria, is recorded from Fuerteventura for the first time. Further butterfly sightings from the same location in Costa Calma are reported, among them the first egg-laying record of Leptotes pirithous (Linnaeus, 17...

Ground beetle assemblages were studied on short-rotation coppices (SRCs) of different ages, as well as on adjacent arable land as an example of previous usage, and on a hedge as an accompanying nature conservation structure in Cahnsdorf (Southern Brandenburg) and Thammenhain (Northern Saxony). In total, over 7,000 individuals of 88 species were dis...

The animal diversity on short-rotation coppices (SRC) has not yet been investigated adequately. Most research conducted up to now did focus on birds and ground beetles. Their biodiversity, equated with species richness, differs considerably. Diversity of breeding birds is higher in SRC than in agricultural cropland, but generally lower than in fore...

The dragonfly fauna of the eastern part of the nature reserve Barnim and of the northern surrounding area of the town Eberswalde (State Brandenburg, E Germany). The present publication shows the dragonfly fauna in the eastern part of the Nature Reserve Barnim, the surroundings neighbouring to the north of Eberswalde and including the southern part...

In connection with the basic survey for the implementation of the EU Habitats Directive, five Brandenburg lakes of habitat type 3150 were investigated: Densowsee near Annenwalde, Dolgensee near Warnitz, Paulsee near Fürstenberg, Kleiner Plessower See near Neuplötzin and Stübnitzsee near Hohenlychen. The naturally eutrophic lakes are delimited limno...
