    Drying in alpine streams might decrease aquatic-terrestrial trophic linkages by reducing terrestrial predation on aquatic prey. We tested this hypothesis by investigating whether a common riparian predator (hunting spiders) in alpine environments assimilated a lower proportion of aquatic prey with increasing stream intermittency. We used high temporal-resolution data from electrical resistance sensors to map patterns of naturally-occurring flow intermittency across 30 headwater streams of Val Roseg, a glacierized catchment in the Swiss Alps. We collected riparian hunting spiders, as well as potential terrestrial and aquatic macroinvertebrate prey, from streams and their associated riparian zones across two seasons (Alpine spring and summer). We estimated aquatic contributions to spider diets (pA) using (i) a gradient approach with aquatic invertebrate and spider carbon stable isotope ratio values (δ13C), and (ii) Bayesian carbon and nitrogen (δ15N) isotope mixing models. Spider pA from the gradient method were not statistically different from zero in spring (0.08 ± 0.10) and low in summer (0.16 ± 0.04). Mixing models also estimated low dependence on aquatic prey in both seasons, although with potentially higher contributions in summer. Spider diet did not vary with increasing flow intermittency in either season. Our results suggested that alpine hunting spiders obtain most of their carbon from terrestrial prey. The slight increase in spider pA during summer may correlate with peak emergence periods for aquatic insects, indicating opportunistic feeding by this riparian predator.

  • Hydrodynamics of Lake Lugano
    Item type: Journal Article
    Zamboni, F.; Salvadè, Giorgio; Stocker, Kurt; et al. (1992)
    Aquatic Sciences
    The hydrodynamic processes in the Lake of Lugano (Lago di Lugano) have been the object of three major measuring campaigns. The first during summer 1979 in the North Basin, the second in the autumn of 1984 in the South Basin and the last in 1989 again in the North Basin. It is expected that analysis of the collected data in conjunction with theoretical concepts will yield conclusive findings on the driving forces and hydrodynamics of the lake. Numerical models have been applied to the lake and the results have been compared to the measurements. Some models calculate the periods and distributions of amplitude, as well as surface velocities and internal seiches. Other models calculate wind-induced water circulation. Evidence is given to the peculiarities of the North Basin and the difficulties related with the depth-width ratio and with its deep chemical stratification.

  • Long-term changes of alpine stream macroinvertebrates in relation to glacial recession
    Item type: Journal Article

    Alpine landscapes are being rapidly transformed, being fueled by ongoing environmental change and glacial recession. Glacial recession has caused emergence of new stream channels as well as changes in the physico-chemistry of surface waters embedded in glaciated landscapes. Our research examined temporal changes in the physico-chemistry and macroinvertebrates during (1) the elongation of a glacial stream and (2) among different alpine lake networks (inlets, outlets, and downstream sites) over the last 24/25 years. The glacial stream study revealed rapid colonization of the emergent stream following deglaciation as well as colonization of previous sites by novel taxa (some from lower elevations). The water physico-chemical data revealed changes in the habitat template of sites over the study period, especially in respect to water temperature and turbidity. The lake network study also showed changes in macroinvertebrate assemblages over the observation period as well as differences on the basis of lake location and type. Here, lake outlet water temperatures increased more over time at northern than southern Alpine lakes. Further, kryal and rhithral lake outlets differed in response regarding water physico-chemistry and macroinvertebrate diversity. Both studies highlight the importance of monitoring alpine surface waters for better understanding of abiotic and biotic responses to landscape transformation resulting from ongoing and rapid environmental change, especially in relation to glacial recession.
