If you think the seasons are feeling… different, you may be right.
Our new review in Science (@science.org) shows that Earth’s changing rhythms could have major and underestimated consequences for life on Earth. 🌍🧵

This is understandable in light of methodological challenges that using eDNA for studying aquatic parasites brings. Those primarily include the low amount of target parasite DNA in the water, lack of specific and general eDNA-oriented primers & lack of sufficient data in public DNA repositories...
In this chapter, we investigated the application of eDNA-based methods in aquatic parasitology. We found that even though the number of studies using eDNA in aquatic parasitology is recently rising, its overall number is lagging behind other more charismatic aquatic organisms...
It has been a collective effort with a great contributions by Isabel Blasco-Costa, Alejandro Trujillo González & @leeselab.bsky.social. It is also related to our activities within the IMPACT project! Make sure to follow @impact-parasites.bsky.social and check out all other fascinating chapters! 🤩
Nevertheless, parasites DNA traces are in the water and they derive from different sources including adult organisms, larval stages and parasite eggs. Detecting them depends on the methodological choices like choice of filters, amount of water filtered, primers used and DNA extraction method...
With multiple ways of collecting eDNA, also including automated solutions, eDNA can be a promising source of information for studying aquatic parasites non-invasively i.e. without the need for sacrificing the hosts. In the long run, it can become a part of routine biomonitoring...
DNA-based methods have been applied in aquatic parasitology for quite some time now. An increasing number of parasitological studies apply molecular methods for studying parasite diversity and distribution as well as reconstructing their phylogenies and their life cycles...
Environmental DNA has been applied in aquatic ecosystems worldwide primarly for biodiversity assessments, monitoring the spread of invasive species or investigating pathogens in aquaculture, slowly but surely making its way into routine biomonitoring…
Finally, we provide a roadmap for implementation of eDNA-based parasite into routine biomonitoring. It requires a thorough validation through testing & optimisation, currently missing for the majority of parasites. The outcomes need to be discussed with relevant stakeholders & decision-makers...
🚨 Thrilled and honoured to lead the chapter on using #eDNA for studying aquatic #parasites - a part of just-published book on #openaccess Aquatic Parasitology led by @berndsures.bsky.social & @nicojsmit.bsky.social with top parasitologists contributing!
