A landmark environmental law looks ahead

In late December 1973, the United States enacted what some would come to call “the pitbull of environmental laws.” In the 50 years since, the formidable regulatory teeth of the Endangered Species Act (ESA) have been credited with considerable successes, ob ...

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

Alfred Johny Wüest

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 ...

Hydromorphological assessment of sediment augmentation measures in gravel-bed rivers

Christian Mörtl

In the riverine environment, the riverscape, sediment and flow regime are essential drivers for natural habitat dynamics. Today, most water courses in Europe are regulated, and their natural dynamics are impaired. Flood releases coupled with the artificial ...

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 ...

En quête d’habitat intermédiaire périurbain

Emmanuel Rey, Frédéric Frank

S’il est un modèle d’habitat associé aux périphéries urbaines, c’est bien celui de la maison individuelle. Intimement liée à l’essor de la mobilité automobile, la propagation de ce type d’habitation dans les campagnes entourant les villes fait partie intég ...

Species conservation in the face of global environmental changes: surface-based modelling of geo-environmental data to identify vulnerable populations

Estelle Rochat

Human activities are resulting in many land-use changes, particularly due to urbanisation and intensification of agricultural practices. Because of these changes, in addition to climate change, many species are facing habitat degradation. In order to avoid ...

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, Nils Rädecker, Louise Helene Soegaard Jensen, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette

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 ...

On the probabilistic nature of the species-area relation

Andrea Rinaldo, Amos Maritan, Andrea Giometto, Jonathan Giezendanner, Silvia Zaoli

The Species-Area Relation (SAR), which describes the increase in the number of species S with increasing area A, is under intense scrutiny in contemporary ecology, in particular to probe its reliability in predicting the number of species going extinct as ...

Persistence of butterfly populations in fragmented habitats along urban density gradients: motility helps

Stéphane Joost, Estelle Rochat, Ivo Widmer

In a simulation study of genotypes conducted over 100 generations for more than 1600 butterfly’s individuals, we evaluate how the increase of anthropogenic fragmentation and reduction of habitat size along urbanisation gradients (from 7% to 59% of impervio ...

Disturbance-grazer-vegetation interactions maintain habitat diversity in mountain pasture-woodlands

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that forest disturbance significantly contributed to fore ...

The ultimate and proximate mechanisms driving the evolution of long tails in forest deer mice

Susanne Petra Pfeifer

Understanding both the role of selection in driving phenotypic change and its underlying genetic basis remain major challenges in evolutionary biology. Here, we use modern tools to revisit a classic system of local adaptation in the North American deer mou ...

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

Andrea Rinaldo, Andrea Giometto, Florian Altermatt, Francesco Carrara

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 ...

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 ...

Coexistence of specialist and generalist species is shaped by dispersal and environmental factors

Séverine Vuilleumier Varisco

Disentangling the mechanisms mediating the coexistence of habitat specialists and generalists has been a long-standing subject of investigation. However, the roles of species traits and environmental and spatial factors have not been assessed in a unifying ...

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 ...
