The interplay of membrane vesicles and viruses in Archaea
Susanne Erdmann (MPI Bremen)
invited by Martin Könneke

Big Blue Button (BBB)

We use the video conference system BBB (BigBlueButton) for the online broadcasting to enable you to hear ans see the speaker and the slides. Interaction is possible via Chat or by using your microphone. Normally only Speaker and Host activate their camera.

To enter just click the button „Continue to web meeting” above, enter your name and click „Join” / „Beitreten”. Depending on your intention to use your microphone choose the appropriate option in the upcoming dialog. You should see something similar to:

  1. Participants list
  2. Chat – can be used for questions
  3. Activate/deactivate your microphone, should always be muted unless you are invited to activate it
  4. With the small white part you can choose audiodevices
  5. Active/deactivate camera
  6. Start sharing a screen/window (only available for Presenter=Speaker). The dialog varies depending on your browser. We suggest to share whole screen
  7. Hide/show presentation
  8. Raise your hand – a better way is to use the chat

Oceanic turbulence as driver for the air-sea gas exchange
Dr. Leonie Esters (Department of Earth Sciences, Uppsala University, Sweden)

An accurate description of the processes that drive the exchange of climate gases between the atmosphere and water reservoirs such as the oceans and lakes is crucial for climate predictions. In order to estimate the rate of the gas exchange, we need to describe the efficiency of the air-water gas flux, in form of the gas transfer velocity, k. The amount of measurements of the k is limited as it is challenging to measure it directly in the field.

During this talk, the description of the k and its drivers are investigated for the open ocean (cruise in the North Atlantic) and lakes (freshwater lake in mid-Sweden). Both types of water bodies imply different challenges when it comes to understand and describe the driving processes of k. For the oceans, a physical description of k based on measured turbulence is explored. For the lake, the surrounding land causes additional difficulties to conduct measurements of k. During the talk an attempt is presented to correct measured gas flux from potential land-based effects.

Unleashing the power of biodiversity research to tackle society's biggest challenges EO Wilson Lecture
Prof. Dr. Alexandre Antonelli (University of Gothenburg, Sweden)

Nature is our most important asset to tackle the huge and interlinked challenges of biodiversity loss and climate change. I will highlight how the understandig of plant diversity, distribution, threats and uses are paramount to: i) the identification of critical areas for protection through expert-based, remote-sensed and citizen-science gathered data, within artificial intelligence platforms; ii) designing habitat restoration projects that consider context-specific and evidence-based guidelines around species and genetic diversity; and iii) the equitable exploration of useful plant traits, such as new sources of food from orphan and neglected crops and crop wild relatives. A critical theme running through these projects is the integration of systematics into wider societal contexts, which will consolidate biodiversity research as on of this century's most important disciplines.
