Vegetation-environment relationships in alpine mires of the West Carpathians and the Alps

Lucia Sekulova

QuestionsHow do two distant mountain ranges differ in their vegetation-environment relationships, overall species composition and its variability and species richness of vascular plants and bryophytes in alpine fens and bogs? Is the floristic difference co ...

Seasonal patterns of testate amoeba diversity, community structure and species-environment relationships in four Sphagnum-dominated peatlands along a 1300 m altitudinal gradient in Switzerland

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Altitudinal gradients are useful to study the potential effects of climate change on ecosystems. Historically, studies on elevation gradients have primarily focused on macro-organisms and ecosystem processes, while microorganisms have been mostly ignored d ...

Patterns of earthworm communities and species traits in relation to the perturbation gradient of a restored floodplain

Edward Mitchell, Renée-Claire Le Bayon, Bertrand Fournier

Little is known about the diversity and ecology of earthworms in flocdplains, as well as their response to natural and anthropic perturbations (e.g. floods, river channelisation, floodplain restoration). We characterised the patterns of earthworm communiti ...

Testate amoeba analysis of lake sediments: impact of filter size and total count on estimates of density, species richness and assemblage structure

Edward Mitchell

Testate amoebae are informative about palaeoecological conditions, but the methods generally used for their analyses in lake sediments differ from those used for their analyses in peats, making comparisons difficult. This study examines how filter mesh siz ...

Long-term dynamics of aboveground fungal communities in a subalpine Norway spruce forest under elevated nitrogen input

Rita Bütler Sauvain, François Gillet, Simon Egli

As anthropogenic N deposition has been suspected to be the main reason for the decline of macromycetous sporocarp production in forest ecosystems, various N-fertilization experiments were started in the mid 1990s. The dynamics of ectomycorrhizal (root-inha ...

Soil-vegetation patterns in secondary slash and burn successions in Central Menabe, Madagascar

Alexandre Buttler, Jean-Michel Gobat

Slash and burn agriculture is a traditional and predominant land use practice in Madagascar and its relevance in the context of forest preservation is significant. At the end of a cycle of culture, the fields become mostly weed covered and the soil fertili ...

Biogeography, Evolution and Diversity of Free-Living Protists

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 ...

Effect of Lead Pollution on Testate Amoebae Communities living in Sphagnum fallax: an experimental study

Edward Mitchell

We studied the effects of lead pollution on testate amoebae communities living on Sphagnum fallax by growing this moss under controlled conditions. A progressive series of lead (Pb) concentration was used in the growing solution of the mosses: 0 (control), ...

Assessing functional diversity in the field -methodology matters!

Aurélie Thébault

  1. Interpreting the functional diversity of vegetation is important in unravelling the relationship between environmental change, community composition and ecosystem processes. Functional diversity is the range and distribution of functional trait values i ...
