One new record is mentioned each for Tyrol and Salzburg. Kalama aethiops (HORVÂTH, 1905) (Tingidae) and Cardiastethus fasciiventris (GARBIGLETTI, 1869) (Anthocoridae) are mentioned the first time for Austria. The Heteroptera inventory of both federal provinces is not yet completely known and new collections will deliver new records and expand our knowledge on the true bugs of Carinthia and Styria.

Insgesamt wurden 64 Wanzenarten festgestellt. Bei einigen handelt es sich um bisher in der Steiermark sehr selten gefundene Tierarten: Pachycoleus waltli, Arctocorisa carinata, Loricula exilis und Orthotylus fuscescens. Das Gebiet wird für Wanzen als artenreich und naturschutzfachlich wertvoll eingestuft. Von besonderer Bedeutung sind aquatische und semiaquatische Biotope wie Moore, Seen und Teiche mit ihren Verlandungszonen sowie Quellen und Tümpel. Diesbezüglich stellt der militärische Ausbildungs-und Übungsbetrieb im bisherigen Ausmaß (Stand: Dezember 2000) aus öko-entomologischer Sicht keine Gefährdungsquelle dar.

True bugs (Insecta, Heteroptera) are rarely used as indicators in conservation biology. They are regarded unsuitable either because of low explanatory power or lack of specialists. The aim of the present paper is -with a focus on Germany, Austria and Switzerland -to reconsider this judgement by taking a closer look upon current taxonomic and faunistic knowledge, availability of standardized collecting techniques and sampling designs, indicatory value, availability of red lists of endangered species and cost-benefit analyses of collecting and determination. Suggestions for standardized collecting techniques are given for different habitat types. The paper emphasizes the high cost-benefit value of Heteroptera due to their high indicatory value at low costs for collecting and determination. Heteroptera are considered to be very profitable and highly suitable indicators for nature conservation.

Twelve species are recorded for the fi rst time in Carinthia. Currently, the occurrence of 591 Heteroptera species is verifi ed for Carinthia. 18 species (3 %) are considered as regionally extinct (RE), 15 species (2 %) as critically endangered (CR), and 27 species (5 %) as endangered (EN). 41 species (7 %) are considered as vulnerable (VU) and 95 species (16 %) as near threatened (NT). Including 77 species (13 %) considered as data defi cient (DD), 273 species (46 %) are listed in the Red List. Most strongly affected are species of riverine habitats, of bogs, swamps and fens, of aggradated standing waters, and particularly of nutrient poor and semidry grasslands. Carinthia holds nation-wide responsibility for 12 species; thereof an urgent need for targeted conservation action is proposed for fi ve species. In addition to a list of characteristic species, which may be especia...

Fourteen species are recorded the first time for the province. The analyses of 23.420 data records from 2,684 sampling locations revealed a total of 691 Heteroptera species for the province of Styria, which is 76 % of the species known to occur in Austria. Within Austria, eight species are currently known only from Styria. 68 % of the species are considered of least concern including eleven not evaluated non-indigenous species. This means that 32 % are considered endangered to various degrees: 34 species (5 %) are considered “regionally extinct”, most of them are xerothermophilic species of open lands. 30 species (4 %) are considered “critically endangered”, 46 species (7 %) “endangered”, and 56 species (8 %) “vulnerable”. 64 species (9 %) were considered “data deficient” due to unclear taxonomy or lack of d...

But this anthropocentric perspective fails to capture the potential ecological value of these natural disturbances. The Gesäuse National Park is a model-region for investigations of such highly dynamic events because of its distinct relief and extreme weather conditions. This project aims to record and analyse the animal assemblages in these highly dynamic habitats as well as document succession and population structure. 1) Dynamic processes lead to one of the very few permanent and natural vegetationless habitat types in Central Europe outside the alpine zone – i. e. screes and other rocky habitats at various successional stages. In addition to the tight mosaic distribution of a variety of habitats over larger areas, avalanche tracks also offer valuable structures like dead wood and rocks. Remarkable is the sympatric occurrence of the three harvestmen species Trogulus tri...

Within the man-made environment of Central Europa, the beetle preferably inhabits meadows with scattered old fruit trees or park alleys. Osmoderma eremita is strictly protected under annexes II an IV of the European Union’s Habitats Directive and is defined as priority species. As for Carin-thia, historical findings provide extensive knowledge of the beetle’s distribution. Due to con-tinuous loss of biotopes and limited dispersal capabilities, Osmoderma eremita is considered to be threatened with extinction in Carinthia. The study’s goal was representative registration of Osmoderma eremita in Carinthia and the development of recommended protective measures. The analysis of 438 sample sites poten-tially suitable as biotope for the hermit beetle (mainly meadows with scattered fruit trees) reveals low potential of occur...

One restoration site was used as apple plantation until 2001, the other as cornfield until 2009. All sample areas are located in a Natura 2000 site, two of them additionally in a nature reserve. A total of 84 true bug species was recorded. Highest diversity was found in a Mesobromion with 40 and its adjacent restoration site with 39 species. Both Mesobromions were richer in xerothermophilous open-land species than the two restoration sites. The older restoration site (former apple plantation) harbours the lowest number and percentage of red list as well as xerothermophilous open-land species. Ellenberg’s indicator values of the plant communities show this site to be more moist and nutrient-richer. Regarding habitat use by xerothermophilous and epigean species considerable differences were found between Mesobromions and restoratio...

Ihre Forschungen führten sie auch in das Gebiet des heutigen Nationalpark Gesäuse, sodass dutzende Heteropteren bereits aus historischer Zeit von hier bekannt sind.
