How we do it: Species identification

No matter how carefully you look, many of the aquatic flora species can’t be identified by naked eyes only. Some of the specific identification characteristics have to be looked at with a microscope. If you want to identify for example a water moss Oxyrrhyncium speciosum, you have to look at the edges of the leaves … Continue reading How we do it: Species identification

Special species: Algae and diatoms

We all know that increased amounts of filamentous and blue green algae mean eutrophication. This much is clear. All kinds of algae grow much faster than vascular plants and because of that, algae can make use of the excess amounts of nutrients available during the growth season. Algae are tough competitors because they are such … Continue reading Special species: Algae and diatoms

How we do it: diving

Diving is one of our three main methods for collecting biological data from the Bothnian Bay. The other two are drop-videos and wading. https://videopress.com/v/UbhCWIwI?preloadContent=metadata See how we do it! Photos & videos by Metsähallitus. Editing by Suvi Saarnio with FilmoraGO. When we want species data from deeper than 1 meter we do a 100 m … Continue reading How we do it: diving

During the last years I’ve done research and surveys in boreal … Continue reading People behind the scenes: Merja Lipponen

How we do it: modelling anthropogenic pressures

Human impact modelling typically seeks to assess how strong the cumulative impact (Fig. 1.) of anthropogenic ecological stressors is on the ecosystem, i.e. where nature is experiencing stress due to human activities. Impact modelling might in some cases assess the impact of only one specific stressor or activity; in other cases the ecosystem and its … Continue reading How we do it: modelling anthropogenic pressures
