Two years after our first scientific expedition, we returned to the Galápagos Islands—this time with sharper tools, new goals, and even more excitement. Our mission? To dive deeper into the hidden microbial world of Scalesia, the archipelago’s iconic giant daisies, and uncover secrets that even our earlier work only hinted at.

Beavers were reintroduced to the Netherlands in 1988 and the beaver population has grown enormously since then. About six thousand beavers now live in the Netherlands. In the wild, beavers can have very positive effects on their environment by changing it, but is this also true in human-regulated areas?

Blue-green algae disrupt many people's swimming plans. Picture this: the weather is nice and you want to hit the water, but you're out of luck! The beach is closed because of a blue-green algae bloom. But why does a a swimming spot close when that happens?

Inland waters can help us mitigate climate change by storing carbon in the sediments. However, for a long time, they were ignored as a player in carbon sequestration ―the process of removing CO2 from the atmosphere, transforming it, and storing it underground. Carbon sequestration happens in ecosystems all around the world. Forests and oceans are most well-known for sequestering carbon, but freshwater ecosystems are also good at it. To put this in perspective: inland waters might sequester up to 20% of the amount of carbon sequestered by the oceans, even though they cover <5.6% of the oceans’ area.

Microbial communities are vital for ecosystem functions, and utilizing their diversity, particularly in phosphate-solubilising microbial communities, can provide sustainable solutions for agriculture. However, constructing and optimizing these communities present challenges due to complex interactions among microorganisms.

An international research team led by the Netherlands Institute of Ecology (NIOO-KNAW), the University of San Francisco de Quito (USFQ) and the Galápagos Science Centre (GSC) is to search for invisible life on the Galápagos Islands. The diversity of bacteria and other microscopic organisms may not be evident to the naked eye, but it is essential to nature. The research team will uncover the yet unknown microbial world that Darwin could not see. Specific focus is given to microorganisms associated with the islands' giant daisies (Scalesia): unique endemic plants that are currently threatened by extinction.

Grazing by geese can cause a lot of damage to agricultural crops. Goose management aims to reduce such damages, for example by actively reducing population sizes.

Yesterday I digged out the teabags that have been buried in the ground (under the snow as well!) for 3 months to measure decomposition rates in a standardised way.

This summer I grew potato plants in my experimental containers. Potato plants are famous for producing potatoes and at the end of the summer I was left with kilos of them.
