Back to back BCCR seminars
Friday November 9th there will be back to back BCCR seminars at 9:15 in Høyteknologisenteret: Seminarrom 520B1.
The first talk will feature Klaus Steenberg Larsen from the University of Copenhagen titled: "Greenhouse gas exchange in a Danish heathland ecosystem (CLIMAITE) using a novel automatic chamber approach"
We developed a new automatic chamber for measuring the exchange of greenhouse gases (GHGs) between short-statured ecosystems and the atmosphere. The aim is to improve our knowledge of the processes of photosynthesis and respiration with high-frequency data and ultimately to improve our ability to estimate net annual balances for ecosystem GHG exchange in climate experiments. During my talk I will present the newest results - and some challenges - from the more than 30,000 measurements performed so far at the Danish climate experimental site CLIMAITE.
The second talk will feature Paul Kardol from the Swedish University of Agricultural Sciences titled: "There's more in the (boreal) forest than just trees: the importance of mosses and dwarf shrubs for ecosystem functioning"
Boreal forests play a key role in the global carbon (C) budget, and currently serve as net C sinks, but whether boreal forests will continue serving as C sinks under future environmental conditions or shift to C sources is uncertain. It is therefore important to understand the processes underlying the C balance of boreal forests, and how these processes might be affected by environmental change. In the first part of my seminar, I will focus on the role of food web interactions in the ‘bryosphere’ (i.e., the complex of living and dead moss tissue and associated microorganisms and invertebrates); in boreal forests, feather mosses often form a thick, continuous layer on the forest floor. I will discuss how trophic interactions in the bryosphere drive two key ecosystem processes: nitrogen fixation by moss-associated cyanobacteria and the decomposition of vascular plant litter. In the second part of my seminar, I will shift gears, and focus on the effects of understory species and functional group diversity on soil communities and the processes they drive, and on ecosystem multifunctionality. I will also discuss the effects of species loss for plant community productivity and stability. Here, I will show these effects can differ among contrasting ecosystems, and – importantly – that patterns of long-term effects of species loss emerging from artificially and randomly assembled communities may not be representative for what happens in ‘real’ ecosystems.

Workshop: Observational and modeling capabilities of coastal biogeochemistry and ecosystems
On behalf of the Coastal Biogeochemistry and Ecosystems group under the Carbon System research theme at BCCR, we are happy to invite you to our first workshop on ‘Observational and modeling capabilities of coastal biogeochemistry and ecosystems’.
With this inaugural workshop we aim to:
- get an overview over existing activities, interests, and opportunities
- get an overview over observational and modeling capabilities; and discuss challenges
- discuss necessary external collaboration and potential partners
-plan future work and gatherings
Final schedule and titles of presentations will be sent soon.
When: Wednesday, Nov 28 from 9-15h
Where: large meeting room at Jahnebakken 5, U1
Light lunch will be served. Please sign up here by Monday 19.11.18: https://goo.gl/forms/ikPdmdRQtoTTvPIk1
