Palaeoecological evidence for anthropogenic acidification of a kettle-hole peatland in northern Poland

We studied the Holocene developmental history of a small kettle-hole peatland in northern Poland using radiocarbon dating and analyses of pollen, plant macrofossils, and testate amoebae with the aim to sort out the influences of climate change, autogenic s ...

Are Sphagnum-dominated regenerating cutover bogs C sinks or not? A study in the Swiss Jura Mountains with predictions of climate change impacts on the C balance

Alexandre Buttler, Edward Mitchell, Andy Siegenthaler

Growing peatlands are an important long-term carbon (C) sink and thus play a key role in the global C cycle. Vast surfaces of northern peatlands have been mined for peat and are currently abandoned. In these surfaces, secondary vegetation succession takes ...

Carbon balance of a European mountain bog at contrasting stages of regeneration

Alexandre Buttler, Andy Siegenthaler

Carbon dioxide and methane (CH4) fluxes were measured in a cutover bog of the Jura Mountains (France) together with biotic and abiotic variables for two entire vegetation periods in order to compare the carbon balance of the bog at three stages of regenera ...

The ecology of testate amoebae (Protists) in South-Central Alaska peatlands: building transfer function models for paleoenvironmental studies

Edward Mitchell

Testate amoebae are valuable indicators of peatland hydrology and have been used in many palaeoclimatic studies in peatlands. Because the species' ecological optima may vary around the globe, the development of transfer function models is an essential prer ...

Model checking for Synchronous Java

Claude Petitpierre, Duy Vo Duc

In this paper, we present a model-checking toolset for a synchronous version of the Java language (Synchronous Java or in short sJava). The toolset includes a set of extensions to the Bandera and Bogor model-checking frameworks. It inherits thus a large nu ...

Changes in testate amoebae (Protists) communities in a small raised bog. A 40-year study

Edward Mitchell

We analyzed the testate amoebae communities from two sets of moss samples taken forty years apart (1961 and 2001) in the same locations of a peat bog of the Swiss Jura Mountains. Peat cutting and lateral drainage of Le Cachot bog have caused a clear increa ...

Spatio-temporal pattern of bog pine (Pinus uncinata var. rotundata) at the interface with the Norway spruce (Picea abies) belt on the edge of a raised bog in the Jura Mountains, Switzerland

Alexandre Buttler, Jean-Michel Gobat, François Frelechoux

In a bog site in way of paludification, a pine stand is declining, which presently is an infrequent phenomenon on the Swiss Jura scale. A transect was positioned in the bog, from the external and driest part (pine-spruce stand) towards the central and wett ...

Deadlock Detector for Synchronous Java.

Claude Petitpierre

In this paper, we present a work that aims to detect deadlocks in the programs written in the Synchronous Java language (sJava). It is based on an extension to a model-checking framework Bogor that allows the verification of concurrent Java programs. The d ...

Response of testate amoebae (Protozoa) to N and P fertilization in an Arctic wet sedge tundra

Edward Mitchell

There are few data on the effect of long-term manipulations on soil protozoa, and almost nothing is known about soil protozoa in Alaska. I studied the response of testate amoebae to nitrogen and phosphorus addition in an Arctic fen, at Toolik Lake Long-Ter ...

Succession from bog pine (Pinus uncinata var. rotundata) to Norway spruce (Picea abies) stands in relation to anthropic factors in Les Saignolis bog, Jura Mountains, Switzerland

Alexandre Buttler, François Gillet, Jean-Michel Gobat, François Frelechoux

In Jura bogs, on deep and nutrient-poor peat, the ecotone between bog pine forest and Norway spruce forest is sharp and, in a few disturbed situations, no succession pine forest-spruce forest occurs. The bog Les Saignolis lies at the top of an anticline, o ...
