Fish Diversity in Relation to Littoral Habitats in Three Basins of Lake Kivu (East Africa)

In total, 28 of the 29 fish species reported from the Lake Kivu basin occur in the littoral zone of the lake, but information about their structure, occurrence, and the habitats affecting their distribution is largely lacking. The lake's inshore area is po ...

Fulfilling Riverscape – a creative interdisciplinary approach

Giovanni De Cesare, Paolo Perona, Sylvie Tram Nguyen

Hydrological, water technological, managerial and human induced processes affect aquatic, amphibian and terrestrial organisms and their habitats, far beyond the main channel of a river. This Riverscape includes diverse riparian habitats which vary in space ...

Evaluating Alternative Metacommunity Hypotheses for Diatoms in the McMurdo Dry Valleys Using Simulations and Remote Sensing Data

Tyler Joe Kohler

Diatoms are diverse and widespread freshwater Eukaryotes that make excellent microbial subjects for addressing questions in metacommunity ecology. In the McMurdo Dry Valleys of Antarctica, the simple trophic structure of glacier-fed streams provides an ide ...

Amoebocytes facilitate efficient carbon and nitrogen assimilation in the Cassiopea -Symbiodiniaceae symbiosis

Anders Meibom, Stéphane Laurent Escrig, Louise Helene Soegaard Jensen, Sandrine Denise Françoise Bessette, Niclas Heidelberg Lyndby, Nils Rädecker, Michael Kühl

The upside-down jellyfish Cassiopea engages in symbiosis with photosynthetic microalgae that facilitate uptake and recycling of inorganic nutrients. By con- trast to most other symbiotic cnidarians, algal endosymbionts in Cassiopea are not restricted to th ...

A case-study evaluating river rehabilitation alternatives and habitat heterogeneity using the hydromorphological index of diversity

Anton Schleiss, Walter Gostner

Concurrent rehabilitation alternatives were evaluated for a 1900 m reach of the River Etsch in northern Italy using a recently developed Hydro Morphological Index of Diversity (HMID) model. HMID is a new tool enabling quantitative assessments of river rest ...

Marteloscopes as training tools for the retention and conservation of habitat trees in forests

Rita Bütler Sauvain

Recently several initiatives on the political and practical level have aimed at promoting forest biodiversity and at halting the loss of species in forest ecosystems. Nevertheless numerous species are still threatened. The main reason for this phenomenon i ...

An overview of cellular ultrastructure in benthic foraminifera: New observations of rotalid species in the context of existing literature

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

We report systematic transmission electron microscope (TEM) observations of the cellular ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different environments (intertidal mudflat, fjord, and basin) were investigated: Ammo ...

Phenotypic heterogeneity in metabolic traits among single cells of a rare bacterial species in its natural environment quantified with a combination of flow cell sorting and NanoSIMS

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Populations of genetically identical microorganisms residing in the same environment can display marked variability in their phenotypic traits; this phenomenon is termed phenotypic heterogeneity. The relevance of such heterogeneity in natural habitats is u ...

Habitat type as strongest predictor of the body size distribution of Chydorus sphaericus (O. F. Muller) in small water bodies

Vincent Eric Jules Jassey

Chydorus sphaericus, a cladoceran characterized by a wide range of distribution, is often numerous in various water habitats. Its body size is a consequence of environmental characteristics and physiology. The aim of the study focused on the distribution o ...

Complex Interaction of Dendritic Connectivity and Hierarchical Patch Size on Biodiversity in River-Like Landscapes

Andrea Rinaldo, Francesco Carrara, Andrea Giometto, Florian Altermatt

Habitat fragmentation and land use changes are causing major biodiversity losses. Connectivity of the landscape or environmental conditions alone can shape biodiversity patterns. In nature, however, local habitat characteristics are often intrinsically lin ...

Impact of Hydropeaking on Fish and their Habitat

Émilie Person

High-head storage hydropower plants are an important renewable source of energy in alpine areas. Kinetic energy released from water, which is stored in reservoir and diverted through turbines, produces electricity. During daily peaks of energy demand, the ...

Signs of critical transition in the Everglades wetlands in response to climate and anthropogenic changes

Andrea Rinaldo

The increasing pressure of climatic change and anthropogenic activities is predicted to have major effects on ecosystems around the world. With their fragility and sensitivity to hydrologic shifts and land-use changes, wetlands are among the most vulnerabl ...

The Hydro-Morphological Index of Diversity : a Planning Tool for River Restoration Projects

Walter Gostner

Contemporary river engineering must guarantee effective long-term flood protection while also improving stream ecology. Nowadays, river engineering projects must aim at optimizing hydromorphological heterogeneity, as this is an acknowledged basic condition ...

Plant traits across different habitats of the Italian Alps: a comparative analysis between native and alien species

Luca Bragazza

While it is well known that the success of alien plants in new environments greatly depends on their functional traits, to date only a few other studies have tested whether coexisting alien and native species show converging or diverging functional attribu ...

Molecular phylogeny of euglyphid testate amoebae (Cercozoa: Euglyphida) suggests transitions between marine supralittoral and freshwater/terrestrial environments are infrequent

Enrique Lara, Edward Mitchell, Thierry Jean Heger

Marine and freshwater ecosystems are fundamentally different regarding many biotic and abiotic parameters. The physiological adaptations required for an organism to pass the salinity barrier are considerable. Many eukaryotic lineages are restricted to eith ...

A landscape genomics approach to understanding and predicting species distribution

Stéphane Joost

In habitat modelling, an initial step is to define geoenvironmental variables to be included in a predictive model. According to Guisan and Zimmermann (2000), the selection of predictors can be made either arbitrarily, automatically by stepwise procedures, ...

Sensitivity of ancient Lake Ohrid to local anthropogenic impacts and global warming

Alfred Johny Wüest

Human impacts on the few ancient lakes of the world must be assessed, as any change can lead to an irreversible loss of endemic communities. In such an assessment, the sensitivity of Lake Ohrid (Macedonia/Albania; surface area A = 358 km(2), volume V = 55 ...
