The recently published database: “Functional traits data for testate amoebae of Northern Holarctic realm” should be a very useful resource for anyone interested in the study of testate amoeba traits or the use of traits in (palaeo)ecological analyses. The paper is available here:

Two databases of testate amoeba occurrences were recently published by Anatoly Bobrov on the website “Microworld”. The first database is a general database from many places around the world. The second database is on testate amoebae from Sphagnum samples. These two database compile ca. 50 years of research by Anatoly Bobrov. A large proportion of

Contributed by Matt Amesbury and Alex Whittle (Real!) testate amoeba photos used with the kind permission of Ferry Siemensma, Microworld, www.arcella.nl Matt: As testate amoeba analysts, we all spend countless hours staring down the microscope studying and identifying hundreds upon thousands of shells. Perhaps foolishly, I once added up, out of perverse interest, the

Contributed by Evelyn Greeves and Richard Payne Hi, I’m Evelyn Greeves, a second-year biology undergrad at University of York making a brief foray into the world of testate amoebae as part of a research scholarship. I’ve been looking at a novel morphotype of Hyalosphenia papilio found at Cors Fochno, a raised, estuarine Sphagnum bog

Contributed by Edward Mitchell Laboratory of Soil Biodiversity, University of Neuchâtel, Switzerland Vincent Jassey recently reported on tropical testate amoebae and especially those living in tank bromeliads (Jassey, 2017). These habitats are absent from higher latitude regions where winter frost would prevent the growth of such plants. Such “unusual” habitats are likely to house
Contributed by Anush Kosakyan It would be hard to find a testate amoeba lover who does not know the genus Quadrulella. These vase-shaped species are a very unique group within family Hyalospheniidae (Arcellinida) since they are capable of secreting their own square or rectangular shell scales (or plates). These scales are characterisstic only for
By Edward A. D. Mitchell, Laboratory of Soil Biodiversity, University of Neuchâtel, Switzerland With the advent of high throughput sequencing, estimates of global diversity are being totally revised. For us protistologists – arguably much more importantly – so is the picture of how diversity is distributed among the different branches of the tree of

Mitchell Laboratory of Soil Biology, University of Neuchâtel “I’m learning to fly but I ain’t got wings Coming down is the hardest thing” Jeff Lynne/ Tom Petty Since the early days of protistology it has been known that testate amoebae can be transported passively by wind.
Community ecologists study how communities of plants, animals and other organisms vary in space and time, how they interact and what controls these patterns. To do this they usually either observe (more or less) natural communities or conduct experimental manipulation in the field (in situ experiments) or in controlled conditions (mesocosms, microcosms). Observational studies of
