Reindeer grazing history determines the responses of subarctic soil fungal communities to warming and fertilization

Autor: Anna Liisa Ruotsalainen, Maria Väisänen, Saija H K Ahonen, Minna K. Männistö, Henni Ylänne, Sari Stark, Annamari Markkola

Publikováno v: The New phytologistReferences. 232(2)

Composition and functioning of arctic soil fungal communities may alter rapidly due to the ongoing trends of warmer temperatures, shifts in nutrient availability, and shrub encroachment. In addition, the communities may also be intrinsically shaped b

Removal of grazers alters the response of tundra soil carbon to warming and enhanced nitrogen availability

Autor: Sari Stark, Minna K. Männistö, Maria Väisänen, Saija H K Ahonen, Henni Ylänne, Elina Kaarlejärvi, Johan Olofsson

Publikováno v: Ecological Monographs. 90

The circumpolar Arctic is currently facing multiple global changes that have the potential to alter the capacity of tundra soils to store carbon. Yet, predicting changes in soil carbon is hindered ...

Encroachment of shrubs into subalpine grasslands in the Pyrenees modifies the structure of soil fungal communities and soil properties

Autor: Josep Peñuelas, Oriol Grau, József Geml, Annamari Markkola, Saija H K Ahonen, Karita Saravesi, Josep M. Ninot

The encroachment of shrubs into grasslands is common in terrestrial ecosystems dominated by grass. Land abandonment and favourable climatic trends in recent decades have favoured the expansion of shrubs into subalpine grasslands in many mountainous r

Streams and riparian forests depend on each other: A review with a special focus on microbes

Autor: Kaisa Lehosmaa, Heikki Mykrä, Jani Heino, Mari J. Tolkkinen, Saija H K Ahonen

Publikováno v: Forest Ecology and Management. 462:117962

In this review, we draw together the research on the two-way connection of streams and their riparian forests of the boreal zone from ecological points of view. Although the knowledge about stream-riparian interactions has increased considerably rece

Different endophyte communities colonize buds of sprouts compared with mature trees of mountain birch recovered from moth herbivory

Autor: Mysore V. Tejesvi, Karita Saravesi, Johanna Pohjanen, Piippa R. Wäli, Anna Mari Markkola, Marko Suokas, Janne J. Koskimäki, Saija H K Ahonen, Kaisa Haapala, Anna Maria Pirttilä, Pirjo Koivusaari

Plant meristems were previously thought to be sterile. Today, meristem-associated shoot endophytes are mainly reported as contaminants from plant tissue cultures, the number of observed species being very low. However, the few strains characterized h
