Testate amoebae are free-living shelled protists that build a wide range of shells with various sizes, shapes, and compositions. Recent studies showed that xenosomic testate amoebae shells could be indicators of atmospheric particulate matter (PM) deposition. However, no study has yet been conducted to assess the intra-specific mineral, organic, and biologic grain diversity of a single xenosomic species in a natural undisturbed environment. This study aims at providing new information about… Expand
Response of Sphagnum Testate Amoebae to Drainage, Subsequent Re-wetting and Associated Changes in the Moss Carpet – Results from a Three Year Mesocosm Experiment
This is one of the first experiment simulating a disturbance and subsequent recovery in ex-situ mesocosms of Sphagnum peatland focusing on the response of testate amoebae community structure as well as functional traits to water table manipulation to represent useful bioindicators for assessing current and past hydrological changes in SphagnUM peatlands.

Assessing the ecological value of small testate amoebae (<45 μm) in New Zealand peatlands.
Assessment of testate amoeba composition in six peat bogs from New Zealand shows that improved taxonomic resolution of small taxa can provide more informed environmental assessment. Expand
Amoebae Assemble Synthetic Spherical Particles To Form Reproducible Constructs.
Time-lapse photography revealed construction techniques and masonry skills as Difflugia herded particles together, trapped them using phagocytosis, and applied the particles with biocement from inside the developing theca. Expand
Major element residence times in humus from a beech forest: The role of element forms and recycling
Abstract This study presents the relationship between inputs of elements (especially biominerals), their recycling mechanisms and the average residence time of the major elements in mull humus. InExpand

The mineral composition of the tests of ‘testate amoebae’ (Amoebozoa, Arcellinida): The relative importance of grain availability and grain selection
It is concluded that the testate amoebae select grains according to their size from those available within their immediate environment, while their size seems to be a function of the distance from the source. Expand
Potential implications of differential preservation of testate amoeba shells for paleoenvironmental reconstruction in peatlands
The results show that differential shell preservation has little impact on paleohydrological reconstruction from Sphagnum-dominated peatlands, and further work is clearly needed to assess the potential of testate amoebae for paleoecological studies of minerotrophic peatland studies. Expand
Cinderella's helping pigeons of the microbial world: The potential of testate amoebae for identifying cryptotephra.
This work analyzed by X-ray Spectrometry the mineral signature of tephra from the 2011 Puyehue-Cordon Caulle Volcanic Complex (Chile) eruption ash fallout and compared it to that of the shells of 51 individual testate amoebae from 13 samples collected at different distances from the active vent.

Testate amoebae (Protista) communities in Hylocomium splendens (Hedw.) B.S.G. (Bryophyta): relationships with altitude, and moss elemental chemistry.
There was no overall significant relationship between testate amoebae diversity or community structure and altitude, presumably because the sampling protocol aimed at minimizing the variability due to vegetation types and soil heterogeneity, which suggests that previous evidence of altitudinal or latitudinal effects on testates amoEBae diversity may at least in part be due to a sampling bias.

Biostratigraphic and palaeoenvironmental applications of testate amoebae
Current and recently developed applications of testate amoebae analysis to biostratigraphic description of Quaternary sediments and palaeoenvironmental reconstruction are reviewed and the potential for the further exploration and use of the technique is emphasised. Expand
Vertical Micro-Distribution and Response to Nitrogen Deposition of Testate Amoebae in Sphagnum
There was no overall response of testate amoebae to N, although one species was significantly more abundant in the fertilized than in the control plots, and species richness increased with depth. Expand
Environmental control on shell structure and composition of agglutinated foraminifera along a proximal-distal transect in the Marmara Sea
Abstract The study of benthic foraminifera in a complex marine system, like the Marmara Sea, is a key for understanding the influence of environmental factors on foraminiferal species, density,Expand
Surface analysis of agglutinated benthic foraminifera through ESEM–EDS and Raman analyses: An expeditious approach for tracing mineral diversity
Abstract The use of an ESEM–EDS (Environmental Scanning Electron Microscope coupled with an Energy Dispersive X-ray Spectrometer), refined and corrected by point Raman micro-analyses, enables a rapidExpand
The agglutinated foraminifera from the SW Pacific bathyal sediments of the last 550kyr: Relationship with the deposition of tephra layers
Abstract The agglutinated foraminiferal content from the last 550 kyr record of the IMAGES core MD 97-2114 (Chatham Rise, New Zealand) was analysed in order to detect the possible linkage existingExpand
The distribution of Testacea in northern England is similar to that recorded in other parts of Europe, but the types of association proposed by Harnisch (1927) are of only limited application. Expand
