Did you know mayflies are among the oldest insects, with fossils over 300 million years old?
Cloeon dipterum is a type of mayfly. This photo shows a female in the subimago stage—a short, non-feeding phase between nymph and adult. She uses energy stored as a nymph and will molt one last time to become a full adult. Mayflies are very sensitive to pollution, so they are used to check how healthy freshwater habitats are!

Bioindicator for the occurrence of #PFAS
The liver of wild boar indicates the level of PFAS contamination
Per- and polyfluoroalkyl substances (PFAS) are considered to be forever chemicals. Many are toxic; others are highly mobile or accumulate in the food chain. However, all are extremely persistent and are spread throughout the environment. The contamination hot-spots of the PFAS can be proven only with a great deal of effort. This is why indicators are needed. According to an article in Science of the Total Environment written by a research team coordinated at the Helmholtz Centre for Environmental Research (UFZ), the liver of wild boars can be used as a bioindicator for this purpose. It shows the level and the nature of the PFAS contamination.

So, what did we find? Well, in young #seabirds, body mass influences the likelihood of survival in the critical period between nest departure & recruitment to the breeding population. For this study, we measured #shearwater chicks to determine how body condition changed over 13 years (an incredible long-term dataset!).
During 2010–2022, we found chick body mass & 3 measures of size (eg. wing length) declined by up to 0.23 mm/yr with body mass declining by 16 g/yr 📏📉😢
In the 1st photo, a healthy chick is shown on the LEFT while an undersized chick which we more commonly observed is shown on the RIGHT.
Overall, the number of chicks fledging (leaving the nest) at <400 g has increased sharply in recent years (see photo 2), meaning significant numbers of birds are unlikely to survive after departing the island
This paper highlights the value of #LongTermMonitoring & critical role #philanthropy has played: literally NONE of this world-class science would have been possible without support from generous donors, especially Detached Hobart - we are forever grateful! 😍🐦💙 Huge thanks to Justin Gilligan for providing the stunning (yet sad) 📸, they made all the difference to this paper! Finally, a massive thanks to @nhmscience and Esperance Tjaltjraak for supporting our team 🙏

#postdocjob in #MolecularEcology with my friend, collaborator and excellent PI material Tristan Cordier, in Bergen, Norway (not Europe's sunniest small big city but perhaps the most beautiful)
2y (extendable) in two EU projects (BIOcean5D and ANERIS). Tasks include :
- developing SLIM to integrate long-reads, metaG and metaT processing
- identifying #eDNA based #bioindicator s of marine ecosystems health
Room to develop own ideas and seek funding. Deadline Feb 15
