How we do it: modeling of potential habitats for Fourleaf mare’s tail

One of the aims of the project is combining the data from Sweden and Finland and seeing what we can glean from the full data. One thing you notice very quickly from a full dataset is an absence of a species from one country, when it is present in the other. Especially if it’s a … Continue reading How we do it: modeling of potential habitats for Fourleaf mare’s tail

We have it, you don’t

The nature in the northern Bothnian Bay in the SEAmBOTH area is in many ways similar on the Swedish and on the Finnish side. Sure, the Finnish side is more flat and the shores do not slope as fast as on the Swedish side, but both have large river estuaries, many lagoons and bays, with … Continue reading We have it, you don’t

Special species: Braun’s stonewort (Chara braunii)

The northern Bothnian Bay is shared by Finland and Sweden, and in many ways the sea is the same. In other ways, differences occur in underwater nature between both sides of the border, although this border only is a human concept and does not affect marine life. One thing that has puzzled our colleagues on … Continue reading Special species: Braun’s stonewort (Chara braunii)

Special species: Nuttall’s waterweed – an invasive species

Waterweeds (Elodea spp.) are species of aquatic plants that originate in North America. Now, because of human interference, two different waterweed species are spreading globally, causing havoc as they outcompete local flora. Canadian waterweed, Elodea canadensis, is no new acquaintance here, as this species was first found in both Finland and Sweden in the 1870s. … Continue reading Special species: Nuttall’s waterweed – an invasive species

Special species: Vaucheria

Filamentous algae are those thin fussy-looking, sometimes slimy, algae may find growing on hard substrates where they cover rocks and stones.Some of them though grow on soft bottoms. Examples of these algae that specialize in growing on soft sediments are species of the genus Vaucheria. Vaucheria are yellow-green algae that grow long, tube formed and … Continue reading Special species: Vaucheria

Special Species: Indicators

Indicator species means a species which tells something important about its environment or the environmental conditions where it thrives. Bladder wrack Fucus vesiculosus deteriorates in turbid water and the plants move towards the surface to catch more light, blue mussels need at least 4-5 per mill salinity to survive, and Vaucheria sp filamentous algae grow … Continue reading Special Species: Indicators
