Article
Mountain ecosystems are sensitive and reliable indicators of climate change. Long-term studies may be extremely useful in assessing the responses of high-elevation ecosystems to climate change and other anthropogenic drivers from a broad ecological perspective. Mountain research sites within the LTER (Long-Term Ecological Research) network are repr...

The biodiversity of glacier-fed streams is particularly threatened by climate change, emphasising the need of monitoring these sentinel systems. The glacier-fed Saldur stream is an International Long Term Ecological Research (ILTER) site in the Italian Central Eastern Alps. Here, we sampled benthic macroinvertebrates and measured environmental vari...

1. In the European Alps, due to the current changes in land use driven by different social and economic factors, grasslands and pastures are being increasingly replaced by forests. Whereas many studies have focused on the impacts of urbani-sation and intensive agricultural activities, no study has evaluated the effects of changes among types of nat...
Article
Full-text available
The increasing incentives stemming from many international initiatives that target sustainable energy production have led to the global success of small hydropower plants. However, there is a growing debate about the actual environmental impact these structures have on riverine ecosystems, to the extent that some researchers argue that they could h...
Article
Full-text available
Currently, across the entire European river network, there are an estimated 0.74 barriers per kilometer of river length, with hydropower production being the main cause of riverine habitat fragmentation. On the one hand, policy actions have been proposed by different institutions to limit this impact. On the other hand, the compelling need to produ...

Permanent ponds represent important habitats for aquatic biodiversity and provide vital ecosystem services as key elements for blue landscape connectivity. Although mostly neglected in management programmes, protection schemes and biodiversity studies in general, ponds constitute habitats with high α- and spatial β-diversity, providing unique habit...
Presentation
Ponds, whilst being mostly neglected in management and protection plans, can constitute habitats with high α- and β-diversity, including many rare and endemic species. In heterogeneous landscapes, ponds can also contribute to habitat connectivity and enhance γ-diversity whilst delivering many ecosystem services. Semi-aquatic insects are one of the...

Whilst being small and shallow, permanent ponds provide valuable habitats for a multitude of organisms as well as provide habitats for animals like aquatic insects and others, including many rare species. These ponds, which were often neglected in limnological studies, were the core of our joint project, the 3rd freshwater project - EUROPONDS in or...
Article
Fish are some of the most threatened vertebrates in the world due to their often-sensitive response to environmental changes. Major land-use changes in the European Alps have direct and indirect impacts on fish communities, and these impacts are expected to increase in the future. Therefore, the identification of factors that are associated with th...

Within the EUROPONDS project we looked into the contribution of aquatic invertebrates to terrestrial ecosystems, which are globally declining, in various countries all over Europe. Our study encompassed a restored quarry in Alpedrete, Madrid, Spain, a landscape destined for livestock activities. We hypothesized that the emergence during autumn and...
Article
Full-text available
High biodiversity is a prerequisite for the integrity, stability, and functioning of global aquatic ecosystems, but it is currently subject to anthropogenic threats. Small freshwater bodies with high habitat diversity are essential to sustain regional biodiversity, but species inventory and biodiversity are largely overlooked, especially in mountai...
Article
Full-text available
The present dataset contains information about aquatic macroinvertebrates and environmental variables collected before and after the implementation of a small “run-of-river” hydropower plant on the Saldur stream, a glacier-fed stream located in the Italian Central-Eastern Alps. Between 2015 and 2019, with two sampling events per year, we collected...
Data
Stream benthic macroinvertebrates have been collected for a period of 5 consecutive years, twice a year (2015-2019, in April/May and in September/October), along a longitudinal transect of the Saldur stream, a near pristine glacier-fed stream located in South Tyrol, Italy (46°N, 10° E), part of the International Long Term Ecological Research (ILTER...

Data
Stream benthic macroinvertebrates have been collected at 14 sites in South Tyrol, on three different sampling occasions (May, July, September), year 2017. Considering the entire hydrological network of South Tyrol, sampling sites were selected according to the following requirements: 1) each sampling site had a homogeneous land cover type at reach...
Article
Full-text available
Aquatic macroinvertebrates are widely used as bioindicators for water quality assessments involving different kinds of disruptive factors, such as hydrological regime variations or pollutant spills. Recently, they demonstrated to be effective in monitoring effects of climate change in alpine stream and rivers. Indeed, since the distribution of macr...
Data
Stream benthic macroinvertebrates have been collected for a period of 6 consecutive years (2010-2015, from April to September, during the glacial melting) along a longitudinal transect of the Saldur stream, a near pristine glacier-fed stream located in South Tyrol, Italy (46°N, 10° E), part of the International Long Term Ecological Research (ILTER)...

Amongst other ecosystems threatened by climate change effects, living conditions in alpine streams in glaciated basins experience considerable changes as glaciers retreat, leading to changing structures of invertebrate populations inhabiting the riverbed. Community structures are monitored in Matsch Valley since 2014, but the species pool and popul...

Question
Hi everybody,
which method/protocol would you suggest to measure total biomass of samples of aquatic macroinvertebrates? Organisms are now "stored" in 75% ethanol.
Thank you!
Question
Hi eveybody,
I saw that several protocols for the analysis of nitrogen wet deposition prescribe the analysis of the collected samples every week.
Would it be fine to perform the analysis of the collected sample every 2 weeks? Are there protocols supporting this timing?
Thanks,
Alberto
Question
Hi,
I performed an ANOSIM analysis with R, using function "anosim" included in package "vegan".
I have read previous discussions regarding ANOSIM and its interpretations, what I can not figure out is how to interpret the "Dissimilarity ranks between and within classes" part, in the output of the function (see picture). How should I interpret that data?

Project
EUROPONDS was selected as the 3rd fresh project, a joint call of the European Federation of Freshwater Sciences (EFFS) board and the EFFS Societies as well as the European Fresh and Young Researchers (EFYR) and representatives of the Fresh Blood for Fresh Water (FBFW). To evaluate the often overlooked ecological contributions and ecosystem services provided by ponds across Europe, we will investigate the taxonomy and biomass (‘biodiversity’) and the energy content and dietary quality, as measured by total lipids and their fatty acids (‘nutritional value for subsequent consumers’) of emerging insects from ponds across Europe. Funding for this project is provided by the EFFS-federated societies.
Project
A permanent biodiversity monitoring system for South Tyrol has been set up under the direction of Eurac Research in collaboration with the Museum for Nature South Tyrol and the Nature Conservation Department of the province of South Tyrol. The monitoring not only serves basic research, but is also intended to provide the scientific basis for political decisions, concerning spatial planning, agriculture and nature conservation The monitoring seeks to survey the species groups that react sensitively to climate and land use change. The project has both a terrestrial and a limnological part. Apart from single taxonomic groups, the survey includes a habitat survey of the surrounding landscape. The surveyed groups are vascular plants, bryophytes, lichens, birds, bats, butterflies, grasshoppers and various soil inhabiting groups. Various additional groups of arthropods (spiders, beetles) are also collected as part of the soil survey, by using pitfall traps and soil extraction. Additionally, arthropods are collected by means of sweep and beeting nets. Vascular plants are monitored via vegetation relevees, while for bats bat loggers are employed, and for birds and grasshoppers vocal identification is used. Bryophytes and lichens are collected within the botanical survey following a standardized protocol. The monitoring covers 320 study sites which will be surveyed within a period of 5 years. The surveys of a certain habitat type will be distributed evenly over this time span. The study sites are distributed over the country (7400 km2) and include a representative selection of habitats. Apart from man-made and managed habitats, a range of alpine habitats which are highly sensitve to climate change are also being studied. The project aims also at fostering biodiversity research in South Tyrol, at connecting different actors and stakeholders and at raising awareness for biodiversity issues in the public.
Project
Mit zunehmender Nutzung unserer Kulturlandschaft unterliegen auch die Gewässersysteme einem ansteigenden Einfluss durch diverse anthropogene Maßnahmen. Die meisten Gewässer sind durch Eingriffskombinationen mehrfach belastet, ein sich daraus ergebender Multiplikationseffekt kann zu dramatischen Veränderungen der aquatischen Lebensräume und ihrer Organismengemeinschaften führen. Als Qualitätsindikatoren für Gewässersysteme werden europaweit Fische als Bioindikatoren verwendet. Über das vorhandene Artenspektrum, die Abundanz- und Dominanzverhältnisse und den Populationsaufbau der einzelnen Arten können verlässliche Aussagen über den Zustand eines Gewässers getätigt werden. Die teilweise dramatischen Veränderungen der Fischfauna in Tirol und Südtirol reichen vom lokalen Rückgang einzelner Populationen bis zur aktuellen Bedrohung der Bestände und im Einzelfall sogar bis zum Verschwinden von Arten. Eine weitere Bedrohung liegt in der genetischen Verunreinigung der ursprünglichen Arten durch Fehlbesatz. Durch diese Fehlbewirtschaftung kann es zum Verschwinden autochthoner Arten kommen. Im Gegensatz zu den meisten bisherigen Untersuchungen sollen nicht einzelne Verursacher, sondern die Kombination möglichst aller Einflüsse großräumig erfasst und mit Hilfe geostatistischer und skalenübergreifender Modelle erkennbar gemacht werden. Die daraus gewonnenen Erkenntnisse sollen bei zukünftigen Entscheidungen bezüglich Gewässer- und Umweltmanagement eine wichtige Hilfe darstellen.
