To address ongoing threats from human pressures and climate changes, water managers and users require a
visual tool that provides accurate information about the health of waterbodies for decision making. However, there
is a lack of less sophisticated methods, such as biotic scoring, to assess the health of rivers in West Africa. To
bridge this g...
The cave cricket Troglophilus neglectus Krauss,1879 (Orthoptera: Rhaphidophoridae) is continuing its spread in Austria. - New records of Troglophilus neglectus indicate a further spread of this cave cricket in Austria. Various observers found the species in East Tyrol south of the main Alpine ridge and north of it in Ebensee (Upper Austria) under l...
The inventory of butterfly and moth species occurring in subterranean habitats in Austria has appeared virtually complete since the compilations of Strouhal & Vornatscher (1975) and Christian & Moog (1982). After 30 years of no additions to the species list, Moog et al. (2021) reported a steep increase in the number of “cave moths” from 2015 onward...
Conserving aquatic resources in the West African Sahel requires water management tools to assess the ecological status of surface water bodies threatened by mounting pressures from agricultural intensification and urbanization. Macroinvertebrate communities of Sahelian rivers were examined to test if a multi-metric index approach could be developed...

Between 2015 and 2019, the list of Lepidoptera from “cave” habitats (i.e., proper caves, rock shelters and artificial subterranean structures) in Austria grew from 17 to 62 species, although the effort of data collection remained nearly constant from the late 1970s onwards. The newly recorded moths and butterflies were resting in caves during dayti...
The composition and species diversity of the mollusc fauna of near-natural and anthropogenically influenced sites in the cadastral community of Tattendorf in Lower Austria were investigated. Near-natural sites included the water bodies and floodplains of the rivers Triesting and Piesting, a floodplain pond, reed beds and dry grasslands. The Triesti...
Abstract
The mollusc fauna of dry grassland sites in Tattendorf. The present survey of the land snail fauna of Tattendorf's dry grassland sites is an important basis for a technically well-founded dry grassland management of the protected natural monument "Trockenrasen" in Tattendorf (Vienna Basin, Lower Austria). In addition to the natural monumen...
Differentiated maintenance concept for the natural monument "Trockenrasen" in Tattendorf (Lower Austria). The granting of the protection status "natural monument" by the nature conservancy of Lower Austria is linked to the condition that the municipality of Tattendorf has to subject the area to ongoing care. Stated in detail are "annual mowing, at...
This article describes the discovery, protection and objectives of a basic survey of the flora and fauna of the natural monument “Trockenrasen” in Tattendorf. The ecological value of this comparatively small area of dry grassland (about 0.5 hectare) was more or less well known, but the real richness in species unknown. According to the motto "You c...
The flowering plants at the natural monument "Trockenrasen" in Tattendorf (Lower Austria). The natural monument "Trockenrasen" in Tattendorf and adjacent areas were examined for its flowering plants since the 1990ies.

Several malacological excursions to the spring reserve Harras and Pottenstein in the Upper Triesting Valley in Lower Austria took place from 2014 to 2019. The main goals were to investigate the importance of this spring reserve as a habitat for molluscs in general and for endangered and potentially cavernous species in special. A total of 87 mollus...
Subterranean cavities serve as resting places and hibernation shelters for mosquitoes. In Europe, members of the genus Culex are often the most abundant insects on cave walls. Culex pipiens L., the common house mosquito, exists in two physically very similar, yet genetically and ecologically distinct biotypes (or forms, ‘f.’), namely Cx. pipiens f....
Benthic invertebrates were used as bioindicators to document the effect of restoration measures in the backwater Alte Donau in Vienna, a former side-arm of the Danube. The study covers four periods of lake management: (1): the mesotrophic year before eutrophication (1987), (2): the 2 years of chemical iron chloride treatment aimed at the phosphate...

Subterranean habitats serve as resting places and hibernation shelters for flies (Diptera) from various families including mosquitoes (Culicidae). Species of the genus Culex (often abbreviated as Cx.) are among the most common insects on the cave walls. A subunit of this genus termed the Culex pipiens complex comprises Cx. pipiens and a few other s...
Dredging Austrian Danube harbours becomes necessary to keep the navigation channel free from bed sediment and to insure safe navigation, especially after major floods. In most cases, the excavated substrate is deposited in the free-flowing river section in the vicinity of the mouth of a harbour. The effects of harbour dredging on the biota need to...
In this paper, a monitoring and modelling concept for ecological optimized harbour dredging and fine sediment disposal in large rivers is presented. According to the concept, first a preliminary assessment should be performed previous to the dredging and dumping procedure to derive knowledge about the current status in hydrodynamics, morphology and...
Dam construction goes back in human history for more than 5000 years (e.g., Sadd el-Kafara dam in Egypt for flood protection), but most of the world’s existing dams have been built after the Second World War as consequence or basis of economic development. Today, there are about 6000 existing or planned large hydropower dams (>15 m height) worldwid...
The water that we use, the air that we breathe, and the energy that we consume are limited resources. Among these, “water issues are one of the major problems that humanity must solve for its survival.” This maxim was a key conclusion reached by top-level decision-makers at the first Asia Pacific Water Summit in December 2007, marking the first tim...
Burkina Faso (BF) is a Sahelian country located in West Africa on the arid southern rim of the Sahara. In this region all work and movement revolve around water and its availability, whether in nature or society. The aquatic ecosystems responsible for storing and replenishing the quantity and quality of water are vital for the productivity and food...
Lepidopterans from subterranean habitats in Döbling (Vienna, Austria)

Harbour dredging is an obligatory procedure for maintaining the functionality of ports. Especially after major floods a dredging of Austrian Danube harbours may become necessary to keep the navigation channel free from bed sediments and to insure a safe navigation. In most cases the excavated substrate is deposited in the free flowing river section...
The article describes the river bottom as environment that is tightly linked and connected with the riparian and terrestrial zone as well as with the hyporheic interstitial and the groundwater. A special focus is given on the habitat-specific colonisation by explicit benthic invertebrate assemblages and selected habitat-specialists. Among the miner...
Die ersten Lebendfunde von Viviparus acerosus in Oberösterreich schließen eine wissenschaftlich gut belegte Verbreitungslücke der Donau-Flussdeckelschnecke. Als Grund für das vormals disjunkte Vorkommen dieser oligorheophilen und wärmeliebenden Art wurde die limnologische Veränderung der Donau durch den Zutritt des abflussstärkeren, alpin geprägten...
We studied streams in a rural landscape mosaic of the upper Mara River basin (Mau Forest, Kenya), where native forest has been converted to land uses dominated by various kinds of farming, agriculture and rural human settlements. We investigated scale-dependent effects of these anthropogenic rural activities on macroinvertebrates and physico-chemic...
Aquatische wirbellose Neozoa
Die Datenlage belegt eindeutig, dass sich besonders in den beiden letzten Jahrzehnten die Entdeckungen neuer, nicht heimischer Tierarten in Österreichs Flüssen und Seen häufen. Nach bisherigen Erkenntnissen sind weniger die natürlichen Ausbreitungstendenzen, sondern die menschlichen Aktivitäten daran Schuld. Der Mensch...
As hydro-biological part of a water management plan the ecological status of the rivers Eisbach and Wulka was assessed. While the good saprobic status of both rivers confirmed the efficiency of the water treatment plants in Eisenstadt and Wulkaprodersdorf, massive hydromorphological deficits were noticed. Almost the entire river courses is degraded...
The incorporation of the EU Water Framework Directive in the Austrian Water Law has involved the need to develop new methods for assessing the ecological status of water courses. This article describes and validates an early warning method (Screening) conforming to the water law, which is based on macrozoobenthos as an element of biological quality...
The ASSESS-HKH Field Screening Methodology was carried out to assess the ecological river water quality status of nineteen small to medium sized rivers of the Seti River basin within Pokhara sub-metropolitan city during the lean flow period in March 2007.

We developed a system for the assessment of ecological condition for rivers in the lower mountains and lowlands of the Hindu
Kush-Himalayan region (Pakistan, India, Nepal, Bhutan, and Bangladesh). We used benthic invertebrates collected from 198 rivers,
located in five different ecoregions and covering degradation gradients; samples were taken twic...
Centralized wastewater treatment systems require sophisticated technologies and skilled manpower for their operation and maintenance (O&M). These systems have huge construction as well as O&M costs. Therefore, a Decentralized Wastewater Treatment System (DEWATS) rather than a centralized system might be especially beneficial in developing countries...
Questions
Questions (3)
Although being a zoologist and not a pest exterminator I recently got some inquiries how to control Dreissena mussels. There is indeed a lot of valuable literature about this topic but few information on practical experiences. Can anybody in the research community recommend me a link or an enterprise that works on this topic reliably and eco-sensitive? It would be helpful if this company also operates in Europe.
Best regards, Otto
Dear colleagues,
We intend to develop a benthic invertebrate based multi-metric index to evaluating the ecological quality of rivers in Burkina Faso. Currently we collect literature on IBIs and MMIs with a focus on Africa and found nation-specific fish and benthic multi-metric approaches in Kenya, South Africa, Ethiopia, Cameroon, and Ivory Coast.
We would highly appreciate any information on IBIs and MMIs from other African countries. Best regards, Otto
