Open AccessInteractions between diurnal winds and floodplain mosaics control the insect boundary layer in a river corridor
Insect flight along river corridors is a fundamental process that facilitates sustainable succession and diversity of aquatic and terrestrial insect communities in highly dynamic fluvial environments. This stu...

Article
Spatial and phylogenetic structure of Alpine stonefly assemblages across seven habitats using DNA-species
Stream ecosystems are spatially heterogeneous, with many different habitat patches distributed within a small area. The influence of this heterogeneity on the biodiversity of benthic insect communities is well...

Urban Aquatic Nature-Based Solutions in the Context of Global Change: Uncovering the Social-ecological-technological Framework
Cities host an increasing share of the human population and are continuously pressured by global change drivers, namely climate change, land-use alterations, and pollution. Among the most important negative pr...

Open AccessClimate-induced forest dieback drives compositional changes in insect communities that are more pronounced for rare species
Species richness, abundance and biomass of insects have recently undergone marked declines in Europe. We metabarcoded 211 Malaise-trap samples to investigate whether drought-induced forest dieback and subseque...

Gene Expression Analysis of Litter-Associated Fungi Using RNA-Seq
Studies of RNA expression levels indicate which genes and organisms are active in a particular sample and therefore in particular environmental conditions or life-history stages. The study of gene expression i...

Open AccessDaphnia galeata responds to the exposure to an ichthyosporean gut parasite by down-regulation of immunity and lipid metabolism
Regulatory circuits of infection in the emerging experimental model system, water flea Daphnia and their microparasites, remain largely unknown. Here we provide the first molecular insights into the response of D...

Article
Open AccessShifts among Eukaryota, Bacteria, and Archaea define the vertical organization of a lake sediment
Lake sediments harbor diverse microbial communities that cycle carbon and nutrients while being constantly colonized and potentially buried by organic matter sinking from the water column. The interaction of a...

Open AccessMolecular phylogeny and timing of diversification in Alpine Rhithrogena (Ephemeroptera: Heptageniidae)
Larvae of the Holarctic mayfly genus Rhithrogena Eaton, 1881 (Ephemeroptera, Heptageniidae) are a diverse and abundant member of stream and river communities and are routinely used as bio-indicators of water qual...

Open AccessSex-specific gene expression in the mosquito Culex pipiens f. molestus in response to artificial light at night
Artificial light at night (ALAN) is a typical feature of urban areas and most organisms living in urban or suburban habitats are exposed to low levels of ALAN. Light is one of the most important environmental ...

The towering orogeny of New Guinea as a trigger for arthropod megadiversity
Early studies on Melanesian mountain systems provided insights for fundamental evolutionary and ecological concepts. These island-like systems are thought to provide opportunities in the form of newly formed, ...

Open AccessEffects of predation pressure and resource use on morphological divergence in omnivorous prey fish
Body shape is one of the most variable traits of organisms and responds to a broad array of local selective forces. In freshwater fish, divergent body shapes within single species have been repeatedly observed...

Article
Whole-community DNA barcoding reveals a spatio-temporal continuum of biodiversity at species and genetic levels
A correlation of species and genetic diversity has been proposed but not uniformly supported. Large-scale DNA barcoding provides qualitatively novel data to test for correlations across hierarchical levels (ge...

Open AccessGenetic population structure of sympatric and allopatric populations of Baltic ciscoes (Coregonus albulacomplex, Teleostei, Coregonidae)
Teleost fishes of the Coregonidae are good model systems for studying postglacial evolution, adaptive radiation and ecological speciation. Of particular interest is whether the repeated occurrence of sympatric...

Implications of biological and physical diversity for resilience and resistance patterns within Highly Dynamic River Systems
The structure and function of alluvial Highly Dynamic River Systems (HDRS) are driven by highly variable hydrological disturbance regimes, and alternate between resistant, metastable states and resilient, tran...

DNA-based confirmation that the parasitic wasp Cotesia glomerata (Braconidae, Hymenoptera) is a new threat to endemic butterflies of the Canary Islands
Island-endemic species can be particularly vulnerable to alien invasion. There are many examples of introduced insect parasitoids having a serious impact on endemic butterflies and moths. In 2006, a population...

Article
Longitudinal patterns of genetic diversity and larval density of the riverine caddisfly Hydropsyche orientalis (Trichoptera)
Small local populations may have low levels of genetic diversity, although widespread gene flow may counteract genetic drift and maintain high local diversity. At a larger spatial scale, a relationship between...

Macroinvertebrate diversity in fragmented Alpine streams: implications for freshwater conservation
Lakes and reservoirs disrupt the longitudinal connectivity of streams, considerably affecting benthic macroinvertebrate assemblages and diversity. Changes in assemblage composition within fragments can result ...

Article
Amplified Fragment Length Polymorphism (AFLP) Reveals Species-Specific Markers in the Daphnia Galeata–HyalinaSpecies Complex
Daphnia often occur in species complexes that consist of two or more co-occurring species and their hybrids. Hybrid individuals are often capable of sexual reproduction and so backcrossing with introgression occ...

Effects of a multi-year experimental flood regime on macroinvertebrates downstream of a reservoir
We examined the response of stream macroinvertebrates to a multiple-year experimental flood regime downstream of a large reservoir. Benthic samples were collected from the River Spöl prior to the initial flood...
