Hydroclimatology of dual-peak annual cholera incidence: Insights from a spatially explicit model

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, Marino Gatto

Cholera incidence in some regions of the Indian subcontinent may exhibit two annual peaks although the main environmental drivers that have been linked to the disease (e.g., sea surface temperature, zooplankton abundance, river discharge) peak once per yea ...

Hypolimnetic Oxygen Depletion in Eutrophic Lakes

Alfred Johny Wüest, Beat Mueller

The oxygen-consuming processes in the hypolimnia of freshwater lakes leading to deep-water anoxia are still not well understood, thereby constraining suitable management concepts. This study presents data obtained from 11 eutrophic lakes and suggests a mod ...

Contrasting Species-Environment Relationships in Communities of Testate Amoebae, Bryophytes and Vascular Plants Along the Fen-Bog Gradient

Edward Mitchell, Mariusz Lamentowicz

We studied the vegetation, testate amoebae and abiotic variables (depth of the water table, pH, electrical conductivity, Ca and Mg concentrations of water extracted from mosses) along the bog to extremely rich fen gradient in sub-alpine peatlands of the Up ...

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 ...

The curse of taxonomic uncertainty in biogeographical studies of free-living terrestrial protists: a case study of testate amoebae from Amsterdam Island

Edward Mitchell, Thierry Jean Heger

Aim A current debate in microbial biogeography contrasts two views concerning the distribution of free-living microorganisms. The first view assumes a ubiquitous distribution, while the second view assumes that at least some species have limited geographic ...

Cutover peatland regeneration assessment using organic matter and microbial indicators (bacteria and testate amoebae)

Alexandre Buttler, Edward Mitchell

Cutover peatlands cover large surfaces of high potential value for biodiversity and carbon sequestration function if successfully restored but the evaluation of restoration success is not straighforward. We assessed the bioindicator value of organic mat ...

Potential implications of differential preservation of testate amoebae shells for paleoenvironmental reconstruction in peatlands

Edward Mitchell, Mariusz Lamentowicz

Testate amoebae are now commonly used in paleoenvironmental studies but little is known of their taphonomy. There is some experimental evidence for differential preservation of some testate amoeba shell types over others, but it is unclear what, if any imp ...

Pb uptake by the freshwater alga Chlorella kesslerii in the presence of dissolved organic matter of variable composition

Cristina Lamelas

Dissolved organic matter (DOM) is a complex mixture of ill-defined components,which makes the quantitative understanding ofDOMfunctions in aquatic systems a challenging task.The traditional approach for studying such complex mixtures involves their separat ...

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), ...

Relationship between testate amoebae and atmospheric heavy metals (Pb, Cd, Zn, Ni, Cu, Mn and Fe) accumulated in the moss Barbula indica Hanoi, Vietnam

Edward Mitchell

We studied the relationships between testate amoeba communities and heavy metal (Pb, Cd, Zn, Ni, Cu, Mn, and Fe) concentrations in the moss Barbula indica sampled at 29 sites in and around the city of Hanoi (Vietnam). Our first approach was to compare the ...
