AskScience AMA Series: We're Women in STEM. We use ecological data to fight climate change. Ask us anything!

Posted: 12 Feb 2021 04:00 AM PST

We are scientists working in the Crowther Lab at ETH Zurich:

  • Lalasia Bialic-Murphy, Senior Scientist - /u/LalasiaM I am Lalasia Bialic-Murphy, a Senior Scientist in the Crowther Lab at ETH Zurich and an Adjunct Research Assistant Professor at the University of Tennessee Knoxville. I study the importance of species interactions and abiotic resources (e.g., soil nutrient and water) in shaping the local abundance and geographical distribution of plant populations. I am particularly interested in understanding the mechanisms that drive species rarity and extinction in a changing world. I was also a field biologist for over 12 years, doing rare species management and critical habitat monitoring in Hawai'i. Understanding how on-going environmental change is affecting native ecosystems is critical for developing informed conservation efforts, and this is my passion. Ask me anything. I would also love to hear your experiences and perspectives on these topics. Let's talk!
  • Iris Hordijk, Doctoral Candidate - /u/IrisHordijk I am a third year doctoral student in the Crowther lab, ETH Zürich. My research focusses mainly on global tree species diversity and the relationship with forest functioning. I am interested in the patterns of tree species abundance, what drives species dominance and rarity, and how do dominant species influence forest productivity. Besides, I am passionate about tropical forest ecology and I am involved in a pan-tropical project on forest regeneration with fieldwork in Mexico. Ask me anything you would like to know related to academic life or my research!
  • Niamh Robmann, Data Scientist - /u/nima-rob After my bachelor's degree in Biology where I was mainly interested in anthropology and ecology, I decided to study bioinformatics & computational biology for my master's degree. I ended up doing my master's thesis in the Crowther lab where I was able to combine my interest in ecology and the newly learned tools and knowledge from my master's study program. Now I am working as a Data Scientist in the lab trying to support the group by adding my more data focused perspective.
  • Kenza Amara, Doctoral Candidate - /u/k-amara I am majored in Computer Science and applied mathematics, and chose to apply my technical skills to environmental issues. So, I decided to pursue a Master 2 in Environmental sciences, because I feel very concerned by climate change. I did my Master Thesis at Crowther Lab, which enabled me to work closely with the department of Computer Science at ETH. I will start my PhD in Computer Science in September but I hope to keep close contact with Crowther Lab and its amazing members!
  • Nina Van Tiel, Data Scientist - /u/mountain_goat_11 With a background in bioinformatics and a strong infatuation for coding, I wanted to use my skills to contribute to fighting climate change. Although there is not much fighting in my daily routine, I support projects that strive to understand global ecology and inform responsible ecosystem restoration, for example, by writing efficient code and running machine learning models. I am a feminist with a particular interest in intersectional, eco-, and trans-feminism.

We'll be answering your questions at 14:00-20:00 CET/8:00-14:00 EST (13-19 UT), ask us anything!

Will the first influenza season after all corona restrictions are lifted be worse than before?

Posted: 11 Feb 2021 02:45 PM PST

It is my understanding that our immune system needs, to some extend, "training" or rather some exposure to germs in everyday life to keep us healthy. To my knowledge, this is also why overuse of desinfectants (e.g. every time you touch something in public spaces) is actually a bad thing.

So, I was wondering whether the next influenza season or some other disease could become worse (meaning more people suffer from it or show more severe symptoms) than before because our immune systems won't be up for the task when the corona restrictions are lifted.

Since the Milky Way and Andromeda will eventually merge and grow in size, is it possible for 2 galaxies to snowball until there are no other galaxies?

Posted: 11 Feb 2021 03:30 PM PST

What I mean by snowball is say once the Milky Way and Andromeda collide, since they've grown in mass, they start attracting another galaxy onto a collision course. And then after this that repeats, until it forms one large "super-galaxy" of sorts. This of course most likely wouldn't happen with our 2 galaxies, but out there in the huge universe, there are most likely 2 galaxies that will collide with each other and have good enough conditions to repeat that collision at least a few times, and grow to be a massive galaxy.

But, just as a hypothetical, throwing out the expansion of the universe, and the amount of time it would take for all the galaxies to collide and merge, is this possible?

Is there a relationship between the concept of high entropy and guage symmetry?

Posted: 11 Feb 2021 02:22 PM PST

I'm finishing up "Qbism" by Hans Christian von Baeyer and "The Fabric of the Cosmos" by Brian Greene. I was struck by the similarity of the explanations about the microstates involved in quantifying entropy and the concept of gauge invariance. I can't find much online about the relationship, if there is one. I have a feeling that I may be misunderstanding guage symmetry/invariance so I'll give my best understanding of both. Please correct me on anything that's off!

One concept of entropy would be the number of "microstates" (molecular/atomic structures) that could create a given "macrostate" (observable system). A glass of water has high entropy because the H2O molecules could be organized any-which way and you'd still have the same glass of water.

My understanding of guage symmetry (same as invariance?) its that a field or variable is said to have this property if fiddling with it doesn't change the measurable result.

This makes it seem to me like "high entropy" is a synonym for "guage symmetry", or that there may be some tight connection between the two ideas.

Can someone sort me out please?

Why cant elements with atomic numbers above 94 be found in nature?

Posted: 11 Feb 2021 09:14 AM PST

I thought it had to do with the half life of those elements but Curium 248 has a relatively long half life. Longer than Neptunium isotopes which can be found in trace amounts so why?

Due to gravitational time dilation, do I weigh more when standing up vs laying down?

Are you able to use computers to be able to tell if somebody has a positive or negative opinion using only sounds?

Posted: 11 Feb 2021 07:03 PM PST

So, I have been thinking to myself that there's a lot of emotions that people have and some experiments have even used that, like the plant experiment where they make people say either nice things or mean things to each specific plant, so that makes me think, is there a way for a computer to be able to tell?

Would organisms that live closer to extreme heat have weaker immune systems?

Posted: 11 Feb 2021 10:28 AM PST

Crustaceans like Lava snails, or the animals that live around heat vents near the bottom of the ocean are what I'm curious about.
