Start of a scientific blog

This is the first blog post on my academic website JolleJolles.com. Although I have already been running my own nature and science blog Mudfooted.com for the past four years, I felt a need for a more personal view on science and the academic world and really like to increase the engage more with the public about my own research!

New Blog!

This blog will present my personal view of interesting new findings from the behavioural ecology literature and beyond, additional information, photos and videos about my own research, and my personal opinions and experiences of academia. If you like to be amazed by our wonderful natural world and read about the most recent fascinating scientific discoveries, please go and visit my other blog Mudfooted.com!

There is large temperature variation in the refuge pools we are sampling, with many actually keeping a moderate temperature due to sufficient cover, but others heating up to well over 30C. This large pool ranged between 29C and 33C, which, so far, the Mediterranean barbel still seem to be able to withstand

Just had a fantastic week in Stockholm, attending and presenting at #ISBE2022, the bi-annual conference of the International Society for Behavioural Ecology. So great to see and chat with so many colleagues from around the world and see a week full of highly diverse and inspiring talks at such a great location!

Besides fish, frogs, and snakes, we also occasionally find turtles in our refuge pools! Including this native species, the Tortuga de rierol (Mauremys leprosa)

Aquatic snakes are one of the main predators of fish of the freshwater habitats in the region. In intermittent streams refuge pools may offer a safe haven from droughts but are an ideal location for snakes and other predators to come for a snack. Indeed, almost every day out in the field we saw at least one snake and often multiple individuals looking out for an easy meal. Here you can see the Iberian Grass Snake (Natrix astreptophora), curiously coming towards me while a school of Mediterranean Barbel hurries past. It is larger (up to 125cm) and less common than the Viperine water Snake (Natrix maura), and tends to be less aquatic, so I was really happy to see this individual swimming from up close!

My field technician @galdric98 exploring the Llierca river to document the distribution of fish and location of refuge pools. Here are some of the deepest parts of the river. That is, when there is water. Now it is almost completely dry already and it feels more like walking on the moon #dryriverbed #rivergorge #sadernes #fieldwork #freshwaterfish #freshwaterecology #natgeoexplore #moonwalk

In intermittent streams, not all fish are lucky enough to survive the dry season. Even those that make it to refuge pools may struggle to survive the harsh conditions, and many pools eventually do dry up.. Here you can see a tiny pool in the Borró river in nort-east Catalunya, with plenty of fish but many of them dying in front of our eyes. Research supported by @insidenatgeo and @creaf_ecologia.

A couple of weeks ago I visited the primary school #escolaboragran in Serinya, Girona, to give a biology class to the children of 3r (~8y). I was actually a bit nervous as it was my first talk completely in Catalan, but I believe the children understood everything I said 😅 Besides talking about the natural world around us, and the importance of protecting it, I thought it was nice to explain them about how it is to be a biologist and scientist, and what it is I actually do every day. It was really great interacting with the kids and getting lots of interesting questions. But I was even more happily surprised to suddenly receive a massive notebook with beautiful drawings and explanations of the students about everything I talked about! Hope to soon bring the class with me to the lab and the field.
Fa unes setmanes vaig visitar l'escola primària de Serinya, Girona, per donar una classe de biologia als nens de 3r (~8y). De fet, estava una mica nerviós ja que era la meva primera xerrada així completament en català, però crec que els nens ho van entendre tot 😅 A més de parlar del món natural i de la importància de protegir-lo, he pensat seria bé explicar-los com és ser biòleg i un científic, i el què faig cada dia. Va ser fantàstic interactuar amb els nens i rebre moltes preguntes interessants. Però em va sorprendre encara més de rebre de sobte una llibreta massiva amb dibuixos preciosos i explicacions dels alumnes sobre tot el que vaig parlar! Espero portar aviat la classe amb mi al laboratori i al camp.

While snorkelling in the Bodensee, I found a large number of pikes stalking juvenile fish in the reeds along the shores. The pikes here can easily get 1m and are actually quite easy to approach to within 2m when quiet. Beautiful to see these hunters up close in the wild.
