Above- and below-ground responses to experimental climate forcing in two forb species from montane wooded pastures in Switzerland

Alexandre Buttler, Konstantin Svetlozarov Gavazov

Mountain ecosystems are particularly threatened by ongoing climate change and the species composition of high elevation grasslands is already changing. An open research question is how these ecosystems will adapt to changes in their key environmental const ...

Barcoding analysis and taxonomic revision of Goliathus Lamarck, 1802 (Scarabaeidae, Cetoniinae)

Michele De Palma

We conducted barcoding analysis of valid taxa in the genus Goliathus Lamarck, 1802 and clarified their relationships. Specimens of Goliathus goliatus (Drury, 1770) sampled in tropical rainforests from Cameroon to Kenya display degrees of genetic and phenot ...

High-throughput DNA barcoding of oligochaetes for abundance-based indices to assess the biological quality of sediments in streams and lakes

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

Aquatic oligochaete communities are valuable indicators of the biological quality of sediments in streams and lakes, but identification of specimens to the species level based on morphological features requires solid expertise in taxonomy and is possible o ...

Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil

Alexandre Buttler, Pierre Rémi Mariotte, Lucas Georges Jean-Paul Freund, Mathieu Raymond Santonja

Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...

A minimalist model of extinction and range dynamics of virtual mountain species driven by warming temperatures

Andrea Rinaldo, Enrico Bertuzzo, Jonathan Giezendanner, Damiano Pasetto

A longstanding question in ecology concerns the prediction of the fate of mountain species under climate change, where climatic and geomorphic factors but also endogenous species characteristics are jointly expected to control species distributions. A sign ...

Testing diﬀerent (e)DNA metabarcoding approaches to assess aquatic oligochaete diversity and the biological quality of sediments

Régis Lionel Vivien

Aquatic oligochaetes are important bioindicators of sediment quality in watercourses and lakes, but their morphological identiﬁcation to the species level is challenging and sometimes impossible. The use of DNA barcoding and metabarcoding could greatly fac ...

Taxonomic revision of genus Fornasinius Bertoloni, 1853 with description of new taxa (Scarabaeidae: Cetoniinae)

Michele De Palma

The genus Fornasinius was established in 1853 by Giuseppe BERTOLONI to receive a taxon that was sufficiently distinct from the known representatives of the genus Goliathus Lamarck, 1801, to merit a different placement. Here, the type species of the genus, ...

Genetic Determinism vs. Phenotypic Plasticity in Protist Morphology

Enrique Lara, Edward Mitchell, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek

Untangling the relationships between morphology and phylogeny is key to building a reliable taxonomy, but is especially challenging for protists, where the existence of cryptic or pseudocryptic species makes finding relevant discriminant traits difficult. ...

Stoichiometric N:P flexibility and mycorrhizal symbiosis favour plant resistance against drought

Pierre Rémi Mariotte

Drought induces changes in the nitrogen (N) and phosphorus (P) cycle but most plant species have limited flexibility to take up nutrients under such variable or unbalanced N and P availability. Both the degree of flexibility in plant N:P ratio and of ro ...

Multiple Assembly Rules Drive the Co-occurrence of Orthopteran and Plant Species in Grasslands: Combining Network, Functional and Phylogenetic Approaches

François Gillet, Bertrand Fournier

Understanding the factors underlying the co-occurrence of multiple species remains a challenge in ecology. Biotic interactions, environmental filtering and neutral processes are among the main mechanisms evoked to explain species co-occurrence. However, th ...

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 ...

Effects of Subordinate Plant Species in Plant and Soil Community Structure and Ecosystem Functioning

Pierre Rémi Mariotte

The relevance of biodiversity to human health is an increasing international political issue as it causes concern for ethical and aesthetic reasons, but also has a strong impact on ecosystem properties and ecological goods and services utilised by humanity ...

Minimal State Representation for Open Fluid-Fluid Reaction Systems

Michael Amrhein, Dominique Bonvin, Philippe Müllhaupt, Nirav Pravinbhai Bhatt

Reaction systems are typically represented by first-principles models that describe the evolution of the states (typically concentrations, volume and temperature) by means of conservation equations of differential nature and constitutive equations of algeb ...

Spatial effects on species persistence and implications for biodiversity

Andrea Rinaldo, Enrico Bertuzzo, Samir Suweis, Lorenzo Mari, Amos Maritan

Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time, and organizational complexity. Species-area relationships and species-abundance distributions are exampl ...

Biogeography, Evolution and Diversity of Free-Living Protists : Insights from Testate Amoebae

Thierry Jean Heger

Although widely recognized as essential actors of ecosystem processes and representing a significant part of the Earth's biodiversity, free-living protists are poorly known. Major questions concerning their diversity, ecology, and evolution remain complete ...

Morphology, Biometry, and Taxonomy of Freshwater and Marine Interstitial Cyphoderia (Cercozoa: Euglyphida)

Edward Mitchell, Thierry Jean Heger

Good taxonomy is essential for ecological, biogeographical, and evolutionary studies of any group of organisms. Therefore, we performed detailed light- and scanning electron microscopy (SEM) investigations on the shell ultrastructure and biometric analyses ...
