My first sampling experience this year in mountain lakes was tough but magnificent 🤩 thanks to the team, Javi Sánchez Hernández @ignasiarranz.bsky.social @guillegargomez.bsky.social @biodiversosurjc.bsky.social @iicg-urjc.bsky.social

I'm going to visit Boulder, Colorado, again to join the freshwater zooplankton workshop. Honestly, I'm nervous as always, because English is a big wall to me. I'm not good at listening/speaking. But, I'm really excited to talk about science and receive many feedback and advice, which make me growth.

This is the iconic ‘Tower of the Sun,’ designed by artist Taro Okamoto for Expo 1970 in Japan. It still stands today, and you can even go inside. Did you know that? Inside, you’ll find the ‘Tree of Life.’

My family visited the Hiroshima Peace Memorial Museum. Hiroshima is the site of the first atomic bombing in human history. I found this stone monument there.

War is the work of man.
War is destruction of human life.
War is death.

These are the words of Pope John Paul II, spoken in 1981.

This is a great and useful review!

The 2025 #CAPSOLUTION expedition is finished!
To sample microbes from 31 mountain lakes across the Alps, we drove 5400 km, hiked 130 km and climbed 10,000 m with our gear, braved snow- and thunderstorms, and filtered 4000 L of water. Well done everyone!!

Locations of the 31 mountain lakes across five regions of the European Alps that we sampled this summer. Thanks everyone for your time commitment and hard work - a truly collective effort!
With @maxemilschon.bsky.social, @lqueiss.bsky.social, @drjmpetersen.bsky.social, @sumayrasultanji.bsky.social‬, @hoeferlab.bsky.social, and the rest of the team. Now the lab work begins! 
Here are some of our microbial enrichment cultures from the mountain lakes. The precious collection of filter concentrates for DNA sequencing, light/electron microscopy analysis, and virus isolation.

Raby et al. provide a comprehensive, practical guide for designing and conducting experiments to measure critical thermal limits, with an emphasis on CTmax 🌍 🧪 👇

buff.ly/iZN6Xdg
Diagram of a template design for a CTmax apparatus. Aeration, mixing mechanisms (pump), and heating elements are in an ‘equipment section’ that is physically separated with a screen from the part of the arena containing the animals (‘animal arena’; here with fish). A submerged temperature sensor (or data logger) is used to log temperatures, in addition to a temperature sensor with a display that is used to score CTmax in real time. The time and temperature should only be visible to the data recorder (and/or video camera), not to the person observing animals for end points.
