Figure 2: Example of photographs, received via citizen science, showing Caenoplana variegata collected from domestic pets. (A) Collected from a dog, (B–D) collected from cats. Cat hair still attached to the flatworm is visible in B and C. A, Case #07 in Table 1; B, Case #11; C, Case #12; D, Case #13. A, photograph by Catherine Vaillant; B, C, photographs by anonymous contributors; C, photograph by Floriane Delaval. Anonymous contributors signed a copyright consent for their photographs, but did not wish to have their name included in a publication.

🧵 Today is World Wetlands Day, celebrating the importance of wetlands and their impact on people and the planet! 🌍

Two weeks ago, RTV Drenthe interviewed one of our PhD candidates, Quint van Giersbergen, in a drained peatland in Gasteren, Drenthe.

Same four-panel image as in the original post, with annotations: a horizontal blue rectangle in the top left of the first image and bottom right of the last image, and a vertical red rectangle in the bottom left of the first image and the right of the third image.

Found the other one too now!

NWO funding for research project on the effects of climate change on microbial growth in cooling towers | Radboud University An international research team has received an NWO grant of €700,000 for the research project MicroSafe, which focuses on the impact of climate change on microbial growth in wet cooling towers.

Our new research project MicroSafe focuses on the impact of climate change on microbial growth (such as Legionella) in wet cooling towers. Due to climate change and higher temperatures, the risk of pathogen spread may increase. Read more: www.ru.nl/en/research/... #microbiology #legionella 🧪🦠

The 2025 edition of the SDM course marked the 10th anniversary of this event. It was a real pleasure to engage once again with high-level students, postdocs and senior professionals during this immersive seven-day exploration of the geography of species distributions and interactions.

Wow, I had no idea it was so much less common in the UK

Houdt 'verbeteren' hier ook in dat de onafgeronde coördinaten in GBIF komen? Dat zou tof zijn!

There have been some busy bees 🍯in the department!

Judith van der Knaap and colleagues published a paper in Ecosystems about the contribution of drainage ditches to greenhouse gas emissions in drained peatlands here in the Netherlands.

Next, we will look at if and when invasive species are covered by such keys.

Library of Identification Resources: a FAIR overview of taxonomic keys Biodiversity is declining globally, and ecological research is key to monitor and counteract this decline. Such research requires the taxonomic identification of organisms by both professional and cit...

Our paper on the Library of Identification Resources is out! In it, we describe how and why to record publications for the taxonomic identification of organisms in a FAIR database, and how to query that data to find applicable resources for an insect or a plant in NW Europe.

Flower-filled dikes attract bees: ‘Dikes are insect highways’ | Radboud University A large census conducted on 157 dikes along rivers in the Netherlands revealed that more and rarer bee species live on dikes than previously thought.

A large census conducted on 157 dikes along rivers in the Netherlands revealed that more and rarer bee species live on dikes than previously thought. According to ecologist Constant Swinkels, many more dikes can be made bee-friendly. #bees #science #ecology #dikes www.ru.nl/en/research/...
