Operational perspectives for biodiversity indicators To understand, measure and mitigate biodiversity change, science and policy need to differentiate between diagnostic indicators that capture as many different biodiversity facets as needed, outcome-o...

Happy to announce a short perspective piece as part of a SynCom @helmholtz.de working group. Discussing the breadth of biodiversity indicators, we encourage to differentiate better between multidimensional diagnosis, leading steering & actionable management indicators

Light spectrum matters: Interactive effects of light and nutrients on phytoplankton communities and trophic transfer Overall, our results showed that the spectral quality of light has a significant impact on phytoplankton community dynamics and the biochemical composition of lake seston. Moreover, the results sugge....

I am thrilled to share our new study which has just come out in @journalofecology.bsky.social! We show how the wavelength spectrum of #light shapes #phytoplankton communities, and associated consequences for trophic transfer. Light spectrum matters! 🌈🌊

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. Details: September 23rd 16:00 CEST ; 14:00 UTC Description: Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.

We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

Please sign up & share! forms.gle/MZTxeQs4UpMr...

Thanks for co-leading the paper with me @kasperjmeijer.bsky.social, and a special thanks to @hillebr1.bsky.social, Klemens Eriksson and all co-authors for this great collaborative effort between the @icbm-uol.bsky.social and University of Groningen!

In a synthesis of over 3000 population trends in the Wadden Sea, we show a substantial reorganization of biodiversity with over 38% of populations undergoing significant change (i.e., increases or decreases), identify winners and losers and critical time points of change! dx.doi.org/10.1111/gcb....

Ever wondered how to analyse your experimental data? 🌊🧪🌍

We’ve developed a series of tutorials in R to guide you through analysing & visualising data from single & multiple driver experiments.

Beginners and experts, we've got something for all of you.

Please share!

Concurrent global change and marine heatwaves disturb phototrophic more than heterotrophic protist diversity Anthropogenic pressures like ocean warming, acidification, rising N : P ratios, and marine heatwaves (MHWs) are affecting eukaryotic plankton diversity, though their combined impacts are rarely studi...

Happy to share my final PhD chapter on the simultaneous effects of global change and heatwaves on North Sea protists! It was a pleasure to be a part of this amazing mesocosm project 🙌

My first post is finally here:

I am very excited to share our newest paper in Ecology where we present the temperature-dependent effect of multiple resources on #phytoplankton growth, using gradients of temperatures, light and nutrients.

A big thank you to my co-authors (@marenstriebel.bsky.social, @asterionella.bsky.social, Bence Gergácz, Bence Buttyán, Jens Nejstgaard, Silke Langenheder) and all those who contributed to a wonderful time at the @fieldSITES.bsky.social mesocosm site at Lake Erken with #AQUACOSM.

Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm-induced mixing, or prolonged drought periods. This results in more var...

What a great first thing to do after my holidays: I am excited to share our newest paper in which we mimicked rainfall scenarios as nutrient and cDOM pulses of different frequency and intensity in #mesocosms and disentangled the effects on plankton #stoichiometry! doi.org/10.1002/lno.... @aslo.org
