Alexandra Schmidt and Laura Epp attended the
6th European Conservation Genetics Meeting 2024 in Lausanne, Switzerland (28th-30th of August 2024).
Laura Epp gave a keynote talk: Environmental genomic time series from seasons to millennia: Impacts of climate, humans and tools for long-term biomonitoring
Alexandra Schmidt gave a talk: Paleogenomic insights: unraveling phytoplankton resilience in the Baltic Sea

On Augus 23, 2024, the article "Decoding the Baltic Sea’s past and present: A simple molecular index for ecosystem assessment" got published in Ecological Indicators.
The paper is a joint cooperation of members of WP2 and WP1,
with Alexandra Schmidt being the first author.
We propose extending monitoring time series for phytoplankton using sedimentary ancient DNA and show that a simple two-species ddPCR reaction for a diatom and a dinoflagellate can deliver an index for ecosystem assessment.
We reveal the timing of recent anthropogenic changes and evaluate local ecosystem stability and good ecological status across millennia.

On June 21, 2024, the article "Glimpse of past dynamics: A new set of phytoplankton primers for sedaDNA" got published in Environmental DNA.
The paper is a joint cooperation of members of WP1 and WP2, with Juliane Romahn being the first author.
We published two newly designed primer pairs targeting dinoflagellates and cyanobacteria and compared them with three existing primer pairs.
The study highlights the usage of primer pairs amplifying short fragments and how primer choice affects community composition.

On April 5, 2024, Isabell Hochfeld and Jana Hinners published their article titled
“Evolutionary adaptation to steady or changing environments affects competitive outcomes
in marine phytoplankton” in Limnology and Oceanography. The article presents the results of an
innovative eco-evolutionary ecosystem model for the Baltic Sea, which provide new insights into how the
interplay of phytoplankton competition and adaptation plays out in present and future environments.

The second PhytoArk Meeting took place in Frankfurt from 1st-2nd of March 2023. A two-day retreat between the PI's and the young scientists was used to discuss the current status and progress of the project. Elinor Andrén and Jérôme Kaiser joined the meeting online. The next event with all participants is planned in Konstanz this autumn.
