Article
Full-text available
Understanding the molecular mechanisms underlying thermal tolerance of aquatic invertebrates can inform predictions about the effects of thermal regime changes on these species. While gene expression and protein abundance changes underlie compensatory responses, little is known about the role of post-translational modifications as thermal tolerance...
Article
Full-text available
Species' acclimation capacities and their ability to maintain molecular homeostasis outside of ideal temperature ranges will partly predict their success following climate-change induced thermal regime shifts. Theory predicts that ectothermic organisms from thermally stable environments have muted plasticities, and that these species may be particu...

Aim Alpine spring ecosystems have long been considered as highly isolated, island-like habitats. This presumption, however, is insufficiently supported empirically and conclusions about spring isolation have been based on indirect evidence. Therefore, we investigated the population genomic structure of Partnunia steinmanni Walter, 1906, a strictly...
Article
Full-text available
Due to a high number of specialized species and unique environmental conditions, alpine spring ecosystems are particularly vulnerable to environmental change and human impact. Therefore, the assessment of ecosystem integrity through habitat monitoring over long periods of time is of particular importance, especially in protected areas. Bioindicatio...
Article
Full-text available
Deducing impacts of environmental change on species and the populations they form in nature is an important goal in contemporary ecology. Achieving this goal is hampered by our limited understanding of the influence of naturally occurring environmental variation on the molecular systems of ecologically relevant species, as the pathways underlying f...
Preprint
Full-text available
Identifying when and where environmental change induces molecular responses in natural populations is an important goal in contemporary ecology. It can aid in identifying molecular signatures of populations experiencing stressful conditions and potentially inform if species are approaching the limits of their tolerance niches. Achieving this goal i...

Background: Water mites are among the most diverse organisms inhabiting freshwater habitats and are considered as substantial part of the species communities in springs. As parasites, Hydrachnidia influence other invertebrates and play an important role in aquatic ecosystems. In Europe, 137 species are known to appear solely in or near springheads...
Article
Full-text available
Species' ecological preferences are often deduced from habitat characteristics thought to represent more or less optimal conditions for physiological functioning. Evolution has led to stenotopic and eurytopic species, the former having decreased niche breadths and lower tolerances to environmental variability. Species inhabiting freshwater springs...
Article
• Springs are distinct freshwater habitats that are threatened globally by human impacts, but are not included in standard freshwater assessment tools. This study analysed how the standard macroinvertebrate metrics currently used in biomonitoring programmes for running waters perform in springs with similar ecological qualities but with a different...
Article
Full-text available
Pesticides can easily reach surface waters via runoff and their potential to have detrimental impacts on freshwater organisms is high. Not much is known about how macroinvertebrates react to glyphosate contamination. In this study we investigated lethal and sublethal effects of the exposure of Gammarus fossarum to Roundup®, a glyphosate-based herbi...

Isolation of natural springs in the Swiss National Park. Islands vs. interconnected patches.
Article
Springs are spatially restricted ecotones usually found at the beginning of a headwaters continuum, which provide distinct environmental conditions, and are inhabited by invertebrate spring specialists called crenobionts. Springs along rivers of higher order with short springbrooks oppose the classical eucrenal-hypocrenalepirhithral continuum and m...
Article
Full-text available
Constant water temperature is thought to be a key factor for macroinvertebrates inhabiting springs. Springs in low mountain ranges are usually fed by deep groundwater. At high altitudes, they are, to a certain degree, fed by surface-near aquifers and are influenced by snow and permafrost meltwater. This may alter temperature constancy. In this stud...

Springs are spatially restricted and insular ecotones. In the Alps, topography enhances this isolation. Springs are to a certain extent inhabited by organisms which are adapted to the relatively constant environmental conditions in springs. We examined thirty-six springs in eight different areas in the Swiss National Park (SNP) to understand if the...

Small waterbodies, including ponds and small lakes, low-order streams, ditches and springs, are the most numerous freshwater environments globally, are critical for freshwater biodiversity and are increasingly recognised for their role in ecosystem service delivery. Small waters often represent the best remaining examples of intact freshwater habit...

First Crunoecia irrorata CO1 results indicate a ”Tabula rasa” phylogeographic pattern in Europe
Article
The canyons in Dinaric karst are known to harbour a diverse aquatic fauna living in springs along the river mainstream. However, the knowledge on the ecology of these springs and also on the springs in mountainous areas of the Balkan Peninsula in general is poor. This study is focused on the macroinvertebrate assemblages of three different types of...
Article
Full-text available
Springs are autochthonous aquatic ecotones with complex functional properties and heterogeneous eco-morphological structures. Within a small spatial extent, invertebrates are highly diverse and mainly composed of species adapted to the surface–subterranean water interface, the aquatic–terrestrial interface or to the spring habitat itself. In this p...

Quellen sind einzigartige Lebensräume mit einer spezialisierten Fauna und relativ stabilen physikochemischen Bedingungen. Die hohe Habitatdiversität in Quellen führt zu einer besonders hohen Artenvielfalt. Das Ziel dieser Arbeit war es, die Artenzusammensetzung von Quellen in drei benachbarten Tälern des Schweizer Nationalparks zu untersuchen. Dazu...
Article
Natural floodplains comprise a spatial mosaic of habitat types that vary in successional development. The physical–chemical properties of soils and sediments in these habitats vary spatio-temporally with changes in hydrology, thereby influencing microbial dynamics and general floodplain functioning. The major goals of this study were to characteriz...

Alpine springs are sensitive ecotones which are inhabited by highly adapted organisms. Studies on how the species assemblages change vertically have not been conducted previously. We investigated 35 natural springs along an altitudinal gradient of about 2000 m in a valley in the Bernese Alps over 2 years. The aim of this study was to investigate th...

The specialised fauna of freshwater springs is affected by contamination of the water with xenobiotics from human activities in the surrounding landscape. We assessed the effects of exposure to toxins in laboratory and field experiments by using copper sulphate as a model substance and Gammarus fossarum Koch, 1836, as the model organism. This amphi...
Article
The effects of an increase in water temperature as a direct consequence of global change on organisms living in springs and spring brooks have rarely been studied in laboratory experiments. In this study, experiments were conducted to test the response of Gammarus fossarum Koch, 1836, as an abundant representative of the European spring fauna, to c...

Article
The specialised fauna of freshwater springs will have to cope with a possible temperature rise owing to Global Change. It is affected additionally by contamination of the water with xenobiotics from human activities in the surrounding landscape. We assessed the combined effects of temperature increase and exposure to toxins in laboratory experiment...

Springs are unique habitats for highly adapted organisms that are endangered by anthropogenic impacts. The springs in the Swiss National Park (SNP) have remained largely free of direct anthropogenic impacts since the foundation of the park. Monitoring of these unaffected Alpine springs is therefore of special interest. In this project 19 springs in...
Article
Discharge variability is an important disturbance factor, and its effect on macroinvertebrate assemblages has been widely studied in river ecosystems. In comparison, few researchers have investigated discharge variability in springs because they are thought to be relatively stable ecosystems and because discharge is not easy to measure in springs....

Springs are ecomorphologically and faunistically diverse freshwater ecosystems. Their limnological classification has been a focus of interest since crenic research began. Despite many attempts to include the crenic fauna in the classification of springs, there is no faunistic crenon typology. Over a three-year period we investigated the macroinver...
Article
Springs are important freshwater habitats that provide specific abiotic conditions for many species. These conditions may change very rapidly downstream. Limnologists tend to treat spring sources and their adjacent springbrooks as a unity because of the lack of clear criteria to separate these sections. In this study, we investigated the longitudin...
Article
Springs are important freshwater habitats that provide refuge for many rare species. In this study, the fauna and abiotic parameters of 20 perennial springs in north-western Switzerland were investigated. Correlation of abiotic and macrozoobenthos data showed that physicochemical parameters had little impact on macrozoobenthic composition, whereas...

Project
Springs are considered highly diverse freshwater ecosystems inhabited by characteristic species assemblages. Due to their insular appearance and specialized species with limited dispersal abilities, especially alpine springs are isolated habitats with relatively low genetic interconnection. Spring assessment methodologies are based on the collection of physicochemical data coupled with faunistic investigations, which, compared to a reference state, provide an overall picture of the ecological status quo of a spring. However, traditional approaches are often based on direct sampling and morphological identification of entire species communities, which can be considered invasive and potentially impact otherwise near-natural habitats. To circumvent these drawbacks, we aim at developing a non-invasive supplementary methods, including targeted indicator species detection with qPCR and metabarcoding of eDNA filtered water samples.
Project
I want to characterise freshwater springs with help of the macroinvertebrate fauna as well as physicochemical parameters and ecomorphological evaluation. Furthermore, I will add knowledge on the land use and its history. The goal is to make a contribution to local education projects and to understand what can be done to conserve springs in Menzenschwand in the future.
