Abstract:
... While many streams and rivers are dominated by terrestrial inputs of organic carbon, algae are an important trophic base for stream food webs. However, the nutritional importance of algae for stream invertebrates only recently has been highlighted. Algae are acknowledged as higher quality food than terrestrial organic matter for the growth and reproduction of invertebrates. In part, this is becaus ...

Abstract:
... Alder trees (Alnus spp.) are key nitrogen‐fixing riparian species in the northern hemisphere. Inputs of nitrogen‐rich leaf litter from alder into stream food webs can contribute significantly to nitrogen dynamics at local and landscape scales. Alder trees also provide habitats for terrestrial and aquatic organisms, and help stabilize river banks. Recently, substantial declines in alder stands have ...

Abstract:
... The response of planktonic (phytoplankton, ciliates, rotifers and crustaceans) and littoral (Ephemeroptera, Plecoptera, Trichoptera and Heteroptera: Nepomorpha) assemblages to chemical recovery was studied over a twelve‐year period (1999–2011) in eight glacial lakes in the Bohemian Forest (central Europe). The region suffered from high atmospheric pollution from the 1950s to the late 1980s, but ha ...

Abstract:
... Increased concentration of dissolved organic carbon (DOC) in northern watersheds is a concern. Such browning affects aquatic food webs and biodiversity in multiple ways, not least through increased attenuation of short‐wave UV radiation, which may facilitate establishment of new predators. We examined the effects of browning on occurrence of the predatory larvae of the phantom midge, Chaoborus nyb ...

Abstract:
... Anadromous fishes are well known to shape the structure and function of recipient ecosystems by introducing nutrients and rich organic matter from the ocean. In contrast, the importance of potamodromous migrations, confined to freshwater, and the subsidies they provide to stream ecosystems has received much less attention. Our objective was to determine the importance of excretion, eggs, milt, and ...
