Symposium LahtiLakes 2018

Symposium LahtiLakes 2018
I just registered for the symposium "Restoration of eutrophic lakes: Current practices and future challenges". This will be held 4.-6. June 2018 in Lahti, Finland. Lahti-city lies on the shore of the lake Vesijärvi (= Waterlake, sometimes one doubts on the ability of the Finns to come up with original names for things), one of the most closely studied lakes in Finland. After suffering from he...

3D X-ray microscopy

3D X-ray microscopy
Just followed a webinar from Zeiss: Basics and Significant Applications of 3D X-ray microscopy (XRM). What a wonderful world of excellent 3-dimensional pictures!! What a fine details! No staining needed. No dissecting. And still you get really detailed, clear 3-dimensional pictures. Bubbling with ideas what one could do with this technology and plankton...

Training course on zooplankton identification II

Training course on zooplankton identification II
Last week I spent on the island of Seili, near Turku (Finland). Together with Prof. emeritus Ilppo Vuorinen teaching an eager, international group of people how to identify and count zooplankton and how to use the microscopes. The course was organized by the university of Turku, The Archipelago Research Institute at their research station. I am looking forward to the next time!

Diatom Flora of Britain and Ireland

Diatom Flora of Britain and Ireland
A new algae site has seen the light: Diatom Flora of Britain and Ireland. Looks nice and solid. Much information about the morphology and very nice pictures. Major part of them clear black and white photos of prepared, cleaned frustules. I would have expected more photos with chloroplasts though, knowing Eileen Cox is involved. She did write a whole book back in 1996 about the inner life o...

New phytoplankton key

New phytoplankton key
Today the programming of the new, visual phytoplankton key started. New approach, both to content and illustration, should make a change. I can see a whole new generation of plankton identifiers clapping their hands eagerly. Although more and more identification work is taken over by DNA-specialists and automatised analysis, there is still need for good old-fashioned identification work. Here i...

Water Map

Water Map
Today a new version of the Water Map of Finland was published. One can see a particular water, or over a larger area. Like the island of Kemiö: If you choose to see the ecological status of the waters, you get this: Yellow means "moderate" status. The Archipelago Sea is not feeling well. And that we all know, who live near by. Only 5 lakes have any kind of ecological status on the i...

Phacus rotunda in Finland

Phacus rotunda in Finland
You might like to call all the large Phacus with a long tail just longicauda. But no. There is more to it. Ever since Ehrenberg described the species in 1831 there has been a wide variety of names for different taxa in this group. A group of Polish researchers recently wrote a nice paper about the Phacus longicauda complex. They described 8 different species, that all have a long tail.There is a n...
