Speaker 1: Ane Vollsnes, UiO

Title: Field work at Iškoras and input to transpiration modelling.


Speaker 2: Ragnhild Gya, UiB

Title:  Indirect effects of climate change on alpine plant communities (the INCLINE project).


Speaker 3: Michal Torma, NHM and UiO

NiN mapping in Northern Norway.

Please find the pdf presentation by Ane Vollsnes on this link, Ragnhild Gya on this link, and Michal Torma on this link.

The recordings of the webinar were due to technical problems split into part one and part two.


Introduction to the first talk, by Ane:

We collected some data related to evapotranspiration at Iškoras. In addition, we started working on quantifying one important parameter in modelling water use efficiency and drought responses in global vegetation models, i.e. the minimum conductance. The work was inspired by a review paper (Duursma et al 2018). The g0 parameter is often estimated from a regression in the Ball-Berry model, although the understanding of leaf cuticles has increased since the model was first published. Our work focuses on plant species from humid conditions.


Introduction to the second talk, by Ragnhild:

The warming of mountainous areas due to climate change is facilitating plant migration upslope, introducing new species in the mountains. In the INCLINE project we investigate how the combination of a warmer climate, and introduction of new species alter the plant communities in the mountains. We are doing this by combining warming with open top chambers and a transplant experiment of lowland plants into the alpine plant community. With the open top chambers we are linked to the ITEX network and collaborate with them. The transplant experiment is based on functional traits to generalize the findings to include what traits on lowland species have which effect the mountain plant community.


I will give a field report of how the experiment is going in the field, and what we have been doing the last two years. We measure plant community composition (graminoids, frobs, bryophytes and some shrubs), demographical observations (survival, number of leaves, biomass, reproduction), carbon flux measurements, soil samples, microclimate data.
