It is part of the installation of the new PicoQuant FLIM (Fluorescence Lifetime Imaging microscopy) and FCS (Fluorescence Correlation Spectroscopy) add-on to the Zeiss LSM 880 at the Umeå Plant Science Center. There will also be an opportunity for a guided tour to the machine after the seminar for those who are interested.

Speaker: Volker Buschmann from PicoQuant

Place: KB.F3.01, seminar room from the KBC Focus Environment.

Please note: The equipment is placed at UPSC and can be used by those interested with an hourly user fee following a proper introduction and based on equipment availability/occupancy. However as UPSC is working with plants the equipment can only be used at room temperature as there is no incubation chamber or similar on it.

Title: Ecological state changes following fire in North American boreal forests

Host: Vaughan Hurry


Outline for the talk
Wildfire is essential to the maintenance of boreal forest ecosystems. However, climate warming is driving the intensification of wildfire disturbance, with increased frequency, extent, severity and duration of the fire season. These changes are expected to alter the structure, composition and function of northern forests. Previous studies of severe fire events have demonstrated changes in patterns of tree species dominance as a consequence of fire-driven changes in seedbed conditions and seed availability, indicating the potential for state changes in boreal forests in response to warming-induced changes in the wildfire regime. Predicted warmer and drier growing season conditions will likely also influence tree seedling survival following disturbance thereby altering regeneration dynamics. Such changes have the potential to affect a wide range of ecosystem functions of boreal forests including but not limited to productivity and associated land surface – atmosphere exchange, understory community composition and wildlife habitat quality.

To understand drivers of post-fire regeneration, we compiled datasets from over 1600 sites spanning the circumboreal, all of which contain comparable measurements of pre- and post-fire tree species composition and stem densities, fire severity, seed bed characteristics and key environmental metrics such as site moisture conditions; post-fire climate variables were generated from gridded datasets for all studies. We evaluated a common conceptual framework based on the results of previous studies of post-fire regeneration dynamics to determine common drivers of post-fire regeneration across sites. While the most common post-fire trajectory was self-replacement, state changes from the pre-fire dominant taxa were also very common but varied biogeographically. Seed bed conditions were consistently an important predictor of post-fire trajectory based on random forest analyses. Results will be discussed in the context of predicted changes in climate and wildfire disturbance and the implications of this for boreal forest composition and function.

Title:
Fast Talkers and Greedy Merchants: Trying to understand what enables ectomycorrhizal fungi to colonize their hosts, strength of fungal signaling or equality in nutrient exchange

Host: Judith Felten

Abstract of the talk:
In forest ecosystems, tree roots are typically colonized by a range ectomycorrhizal fungi that are thought to supply a range of nutrients in return for plant photosynthate. Despite the prevalence of these important fungi, little is understood concerning the molecular underpinnings of these relationships and where the balance of power in the relationship actually lies. In our co-presented seminar we will split this question into two parts: what is the role of inter-kingdom communication between host and fungal cells to favor the formation of these symbioses and is parity in the exchange of nutrients between the two symbiotic partners required for colonization maintenance and success. Using examples from our high- and medium-throughput screening using the fungus Pisolithus microcarpus and its host Eucalyptus grandis (e.g. sequencing, metabolomics, protein activity analysis), Jonathan will discuss the steps forward we have made in recent years in understanding the evolution and role of both protein- and metabolomic-based dialogue between mutualistic fungi and their hosts. Using stable isotope tracing and transcriptomic analyses, Krista will talk about mechanisms of how nutrient availability and competition in between the two organisms for nutrients affects these interactions. Further, she will talk about mechanisms used by the plant to protect its own interests from unhelpful symbionts, and how these mechanisms affect the exchange of nutrients between the two symbiotic partners.Together, we would like to reflect upon some of the bigger-picture ramifications of these findings and highlight some avenues of research that may be attractive to pursue in the future.
