How to BE an Amateur Biologist

It has been about three months ago since I last wrote my blogpost ‘How to Become an Amateur Biologist 4’. I have been travelling, through Panama, Costa Rica, Nicaragua and Ireland. The latter being a bit of an outlier, but you do everything to see your foremost favourite artist, in my case Theo Katzman. And now, I am sitting here back in my student room in Leiden in the Netherlands, where I just started uni last week again. Back to studying, back to routine and back to the lovely Dutch weather. I wanted to write one last blogpost for Dinalab. To update you on the finishing of my project, but also to reflect on what I have learned at Dinalab, in Gamboa as a certified (self-named ;p) amateur biologist.

Eventually, I ended up making boots (using Andy’s massive old boots), where people could experience what it is like to ‘hear sounds’, or better said perceive vibrations, like a leafcutter ant does. For the boot, I created these ‘legwarmers’ where I sewed into two vibration motors (two in each legwarmer; four in total). In Arduino I wrote a piece of code where the vibration motors outputted data from audio recordings of leafcutters, cutting and foraging leaves. The audio recordings were transposed into numerical values, so the vibrators would vibrate more intense when the values from the audio recordings were higher. These values are abstracted from the amplitude of the audio recording (which is also influenced by pitch in the audio file). However, I wanted to make the experience a little bit more interesting and let all of the four vibrators vibrate at different times and different intensities and speeds. The audio recording consists of multiple ants making ‘sound’, so by letting each vibrator vibrate differently I wanted to recreate the effect of individual ants producing these vibrations/sounds.

I named my project ‘SignificAnt’. Ants are often seen as pests, as little, insignificant creatures. However, ants, or in this case leafcutter ants,  have a very important function relating to decomposition, soil health and other basic ecological functions. So, the name refers to the important and unmissable role that leafcutter ants have and play in the ecosystem. Besides the meaning of ‘significant’ and the clearly recognizable ‘ant’, ‘sign’ is also an important part of the word. Since the concept ‘sign’ plays an important role in Jakob von Uexküll’s Umwelt, the name seemed to fit perfectly.  

I could test out the Significant boots on the first (what an honour!) Dinalab exhibit, which took place on the 11th of June. The week before the exhibition Serena and I have been working incredibly hard, until the late hours, being sleep deprived, eating poorly, but also laughing incredibly hard together. Serena’s delicious tea and listening to Theo Katzman kept us sane. The exhibit was a big success; many people showed up and showed genuine interest. We both presented our own individual projects and our menstruation plant, Andy and Kitty sold lots of keychains for the APPC (including my designs 😊) and lots of people tried out my boots and asked interesting questions. In the evening, me, Josie and Finn organised a goodbye/birthday party and it was the perfect ending to a very fun, but exhausting day.

As the name of the title suggests, in this post I am going to tell you how I became an amateur biologist now. Before going to Dinalab I wrote down some goals and philosophy for my stay there. I will further elaborate on them below.

The goal of the project, or in general for my stay at Dinalab, was firstly to make something physical, as in a physical, tangible product. I am a person that very much lives in my head. I think a lot, so I have a lot of ideas and thoughts about things, however I have great difficulty with bringing out these ideas and thoughts out into the world. Although, it was still super hard and challenging for me to go from a framework, to a question, to a concept and eventually to the actual product, I am glad to say that I did it!!! I learned so much from the whole process. Andy helped me out a lot, which I am very grateful for. So I am happy to check this foremost important goal of my list!

Secondly, think like nature, was another goal. Von Uexküll’s paper is all about this. Studying organisms in its own environment, in its own small little ecosystem, in its own respect. In order to be able to this, you have to think like nature, understand everything that goes on in the world of your subject of study. Although this is actually not very feasible, since it takes a lifetime to understand an organism fully in its own context. Nevertheless, I feel I have been come a little bit closer to thinking like nature, by looking at the leafcutter ants at work day in, day out. I also see ‘think like nature’ more as a philosophy, instead of a plan per se.

One other important goal that I had was to have fun! School and university sometimes makes you lose contact with the having fun part of studying and discovering the world, since the system is based on deadlines, performance and grades. However, this was also harder than expected, since I am a major perfectionist and my project is part of my Master’s degree and gets evaluated. Together with Andy, we made a very basic ‘Ant Gate’ which could detect ants walking through the gate. Luckily, besides having fun making stuff, I also got to have lots of fun with my dearest lab buddy Serena, dancing around Dinalab, singing our souls out, getting angry at the code of our project and catching up on the hot goss of Gamboa. Andy was my partner in crime mindwise, with the same crazy ideas and thoughts about the world, and Kitty was my partner in crime at APPC talking about how cute and funny(looking) sloths are and bashing people of the hotel.

Another goal, although a very basic one, was to get to know and learn about local flora and fauna. I learned so much about different kinds of animals and plants from scientists from the Smithsonian, local people and Kitty and Andy. For example, I learned so much about bats, butterflies, birds, frogs, plants and trees, ants and about lots of other big and small creatures.

And with all this new knowledge comes a new sense of curiosity. Nature keeps on surprising and amazing me and being in the jungle this all became more explicit. It brought me so much inspiration and new interests, and even more questions than answers. I hope to bring this home to the Netherlands. Although the environment is very different, I hope to continue to stay curious, adventurous, open-minded and to be respectful of nature and all its living beings, which in the end, are, for me, the most important character traits of a (amateur) biologist.

Unfortunately, a few days after the Dinalab exhibit my stay was coming to an end and I needed to start getting ready for my big backpacking trip; cleaning up Dinalab and saying goodbye to my dearest Gamboa friends and family. These last days were really stressful and emotional and I had a really hard time saying goodbye to Gamboa, the people, the nature and the animals.

My experience at Dinalab has been beyond my expectations. Andy and Kitty’s hospitality will continue to amaze me, especially considering I have been there for four months and the lines between work and personal life can get blurry. I have met the most amazing people, who have become, still are and will be my friends from Gamboa for life. Also, working at APPC has taught me so much about sloths and the other animals living there. They do incredibly good work and I am very happy to have been part of a team where people care so much about animals and nature. Luckily, there is still so much good in the world 🙂

Thanks to everyone that made my stay at Dinalab and in Gamboa in general so memorable. Thanks for all the help, fun, support, knowledge and crazy adventures. And an extra big shout out to Andy and Kitty, thanks for making me feel so welcome and at home. Thanks for teaching me so many cool new fun facts and skills. And lastly, thank you for letting me mess up Dinalab, using all the cool machines and eating your pizza 😉

Can’t believe that this was my last blog post from my stay at Dinalab (at least for now ;)) I really hope to get back to Gamboa, because I have had the time of my life there! Untill next time. Love you all <3

With lots of love,

How To Become An Amateur Biologist 104

Always when I look back at my blogposts, it surprises me how quick time goes by and how much I have done and learned. Looking at ‘How to become an amateur biologist 103’, all the stuff that I wrote about seems so far away already. Also considering the progress of my project. It feels like ages ago that I have decided to something with sounds and vibrations in ants, but actually it is not even that long ago! Anyway, I guess that’s a good sign, right? Unfortunately, my stay in Gamboa and with that at Dinalab is coming to an end. With only two weeks left I am working hard to finish up my project and enjoy as much of Gamboa, the people, nature and all of its finest things and quirks as possible. However, for now I still have to tell you about everything I have done and learned these past weeks.

A week is never the same here in Gamboa. You might have nothing planned in the night and then someone texts you: “We are leaving to go lizard seeking in five minutes, you wanna join?” And in five minutes you find yourself in your field clothes, boots and headlamp, weaponed with your bugspray , ready to seek some lizards. This actually happened. The Gamboa life, or in general the Latin-America lifestyle, with its chaoticness, leaves more room for spontaneity which I love! It has been a breath of fresh air from the lifestyle in the Netherlands, where everything is very much structured and planned weeks in advance. It is going to be hard adjusting back to these habits in September 😉

The only constants here are doing my project at Dinalab and going to APPC on Friday’s. Scrolling through my pictures, you will mostly find stuff about my project and adorable (and occasionally also scary) animals. APPC has been great, and I am still very much loving my quality one-on-one, or one-on-many time with the sloths. I really am gonna miss them when I leave. Oof, I am already becoming sentimental. I will try to save that for the last one in this series of blogposts. Anyway, new sloth fact: Sloths closest relatives are anteaters and armadillos, and they descent from this massive terresterial sloth that were as big elephants 😮

For my project I was testing out different frequencies and patterns of frequencies on the Leafcutter Ants in front of Dinalab. At one point I noticed that there was some yellow-orangish substance on the piezo disk, which I hadn’t seen before. I cleaned the disk and tried it again on a different part of the trail with the same vibration settings (100hz with a duration of 100ms). Then I saw with my own eyes that (one of) the ants was/were secreting this substance. How exciting!!! But why, what, how and when? 🐜

The vibration pattern seems to elicit some kind of ‘distress’ response in the ants. They start attacking the piezo disk like crazy and try to bite/cut it. Also, when the other ants smelled the substance, they flinched away. The entomologists I have spoken to think the substance is something like faecal matter, or in other words, ant poop. 💩 They told me that, apparently, the matter serves as a fertilizer inside of the nest and as a deterent outside the nest. Maybe when excreted in ‘fear’, an additional chemical compound is added to the excretion, which is called context-dependent chemical signaling. One of the entomologists, Alissa, wants to check what the chemical substance is in the lab, which is super exciting!! Probably it is ‘just’ poop, but it is still very interesting why they excrete this with this type of vibration.

For my end product I am making an installation where people can experience the vibrations that leafcutters make accompanied by the sound that it makes for us. It is literally going to be an experience how it is ‘to stand in someone else’s (in this case something else’s) shoes’. I will not tell you too much details yet; you can see the endresult in the last blogpost or at the exhibition 😉 I have still a lot of work to do in one week, but I hope and believe it’s going to pay off!

Furthermore, recently two new entomologists, or more specifically, myrmecologists, have arrived in Gamboa. Alissa and Stephanie are studying fungus-growing ants (but not the leafcutters) and they have taught me so much new stuff about ants! One time they took me ‘ant digging’, which was so cool and so much fun. I even got to dig up ‘my own’ colony and write my initials on the sampling cup. The species we dug up is Serciomyrmex Amabilis, a little fury fungus-growing ant. The cool thing is that some colonies are infiltrated by a certain type of ant, Megalomyrmex symmetochus. These ants are not fungus-farming ants, so they don’t help with caring for the garden and thus they are seen as parasites. Mega is a social parasite since it lives together with the host. Unfortunately for Sercio, they do eat from the garden and profit from it. At first instance this seems like parasitism (thus the name parasite as well), however, the parasites do protect the fungus by attacking other intruders. Alissa, Stephany and their research team say it may be a context-dependent mutualist since it also defends their host from other threats! Super interesting, right?

I have also starting to make two designs for the recycled plastic keychains that Kitty and Andy make and sell for the APPC. I really like the shape of the Cecropia leaves, which I see a lot around here because that’s what we get for Valencia the Taipir and the three-toeth sloths a lot, since it’s their favourite. Another design I made is, of course, of the leafcutter ant! I have spray painted them with some pretty colours and now they are almost ready to be sold! Actually I already sold my first (cecropia) design and I hope to sell more on the exhibition I am going to give at the end of my stay here 😊

Cool2 is also still in the game. We have been playing around more with Arduino and an LED strip. Slowly but steadily we are making progress and hopefully in one or two weeks we have a prototype to show and present! Besides our menstruation plant, Kitty taught Cool2 how to crochet. Kitty was an excellent teacher but crocheting is not my calling. It was nice, but I am a bit too restless for such detailed work. Serena loved it though and she made some really cool stuff, which you will probably see in one of her blogposts 😉

Serena organised a jungle crafting afternoon where we got to make something out of the materials that we found in the forest, to explain a (scientific) concept with. Although my thing didn’t fully work out as I wanted, I really did learn to get outside of my head. It was a super fun experience!

Lastly but not least, I did a bunch of fun stuff here with my amazing Gamboa friends. We went a drag contest in the city, we visited the Biomuseo, Team Dinalab (me, Serena, Andy & Kitty) had a nice beachday at Forte Sherman, we had our second ruin party, we played Capuchin Heights (Andy’s self-made Carcassonne), went on a few night hikes/walks and of course some good old sunset hangouts!

See you until my last blogpost of this series:

How To Become An Amateur Biologist 103

Hey everyone!

The time flies here. On one hand that is a positive given but on the other hand it also means that time start getting short to work and finish my project. These past few weeks have been very fruitful. While Andy and Kitty were away to Sri Lanka to organise stuff for DinaCon, Serena, Jorge and I were ‘in charge’ of the Dinalab. Besides working on our projects, we had lots of dance parties, ice cream celebrations and movie nights.

After two and a half months with a lot of researching, experimenting and seeking inspiration, I decided to do my project here at Dinalab about Leafcutter Ants. With the concept of Umwelt in mind, I try to ga in a little bit more insight in how these ants perceive the(ir) world. Right now, I am experimenting with ‘sound’, or vibrations. Ants don’t make sounds through the air (air-borne), but through surfaces (substrate-borne). With the help of Lisa Schonberg (former DinaCon participant in 2019) I started exploring this with piezo microphones, which are surface microphones. The cool thing is that you can use piezo as a microphone and as a speaker! So besides recording, I am testing whether the Leafcutter ants will react to certain frequencies and changes in frequencies. So excited to find out what is coming from this! Maybe we will even be able to communicate with ants in the future… 🐜

Serena and I started working on our collaborative project under the name ‘Cool2’. We chose three main themes where we wanted to build the project around, which are Nature, Feminism and Arduino. From these themes we started creating a mindmap and picked out four keywords which spoke to us the most. Cycle, misunderstood, meaning and ruthless. Last week we got the idea to make a plant that shows you in which fase of your menstrual cycle you are in by the colour of LED lights. The LEDs will light up when you water or touch it. This is a new way to track your period and to simultaneously learn about periods. The thought behind this was sparked by the fact that a lot of women I know use a period tracker but are not consciously aware of the fase they are in. For example, sometimes I would get quite moody and sad and then in a week or less I get my period. Afterwards I am always like: ‘Oh now I understand, I just needed to get my period!’ What a relief 😉

In the time period when Kitty and Andy I kept on volunteering at the APPC. My love for the sloths grows stronger each day. They are just the cutest things ever! Especially Ingmar, the sloth I named after my supercute cousin. Such a kind soul 💕 New sloth fun fact by the way: sloths have four stomachs, just like cows. Also Mireya taught me a lot about the different plants that the sloths and Valencia the tapir eat. I learned to recognize poro poro, indio desnudo, jobo, cecropia, mango and berignon.

For a long time Andy has been working on trying to sense ants. This has been proven to be a difficult task because they are so tiny, fast and with so many. Andy made a 3D design for a simple ant gate where leafcutters can be sensed. The gate works with a light source (in this case a laser because a laser light is the most stable) and a photoresistor. Right now, the ant gate only works for ants with leaves. If I have time, I will try to make the ant gate better by making it more sensitive to smaller ants, and ants without leaves, as well. Anyway, it was a fun (side) project that involved leafcutters and Arduino!

Serena and I also organised a small Arduino workshop for some students are doing a project with a heart rate sensor and a GPS. We taught them the basics of Arduino and they learned it very quickly. Thank you Daniel and your group for joining us and being so enthusiastic and good students! Good luck with the project 🙂

Luckily there was also enough time to explore the beautiful nature that Gamboa has to offer. I took Serena for the first time to Pipeline Road and she was very happy as you can see in the picture. Last week Andy organised a night hike. It had been a long time since I had been on one so it was very nice to go on one again. We saw so many frogs and I saw my first treefrog! Andy says that you haven’t been to Panama if you haven’t seen one. So fortunately now I can say that I have been in Panama for real!!

And last but not least there was also a lot of time to do fun stuff with my Gamboa friends. We went bowling, partying in the city, watching series and movies and playing tennis and volleyball. For the week I also went to Bocas del Toro with Josie and had a super fun time!

The upcoming weeks I will be working very hard on finishing my project. It will be a lot of recording sounds and videos, experimenting with different sounds, frequencies and other stimuli and combining this to a meaningful endproduct. Hopefully the ants will cooperate and will I be able to share something very special, a glimpse of one part of the Umwelt of a Leafcutter Ant. Can’t wait to unravel the secret life of Leafcutter ant 🕵️‍♀️ I will be back…

How To Become An Amateur Biologist 102

Hey everyone!

It is time for a new sequel on ‘how to become an amateur biologist’, edition 102! More and more I am becoming a true Gamboadian, but more importantly an amateur biologist! Little by little I start to recognize different birds’ songs, calls, colours and shapes and know how to name them. And I love it!! The same accounts for insects, butterflies and to a much lesser extent bats, all thanks to Kitty, Andy and my friends at STRI. At the animal rescue I am also learning so many fun facts about the sloths 🙂 Did you know that sloths are the only mammals whose hair grows downwards instead of to their extremities? No, me neither!

The past three weeks I have been working on multiple things. I have been gathering more information about agouti’s and bats. A few times I had the privilege to join STRI’s Bat lab on their netting expeditions, feeding training and experiments. Leonie, a bat scientist, has taught me so much about Trachops. Trachops are frog eating bats that locate the sound of the Túngara frogs, and with that the frogs itself, with echolocation. Even when the frogs have stopped croaking the bats know where to locate them because of the ripples they make in the water. So, very cool bats. Also, they also just get bonus points for being so darn cute.

Besides observing bats and agouti’s, I have been trying to study them by modelling something of their behaviour in P5js, an online JavaScript editor which allows you to program visually. I organised a small workshop where scientists got an introduction to this programme and got to try out their own ideas about their own subjects of study. Andy and I also reorganized the hardware room, so things are way easier to find now! 🙂

Next to my big project, I am also creating toys for the animals at the rescue center. Last week I, with the help of Andy and some residents at Adopta, have created a first prototype of a food enrichment toy for the spider monkeys. This toy is entirely made out of recycled plastic (besides the metal zip ties which connect the recycled pentagons)! I am very curious what the monkeys think of it, and whether the design works or not. Only time will learn. In the future I want to make other recycled plastic toys, for example cubes with bells, rocks or anything that can make sound. Monkeys love making noise, so I would love to make their life more noisy (and more irritating for us 😉). Serena, my new lab buddy, arrived last week and from the beginning she was thrown deep into the Dinalab hole. Together with Jessie, Andy, Serena and I we made a device where the strength of a butterfly can be measured!

Besides studying animals, programming and creating toys, I have had several very inspiring meetings with a few member of the Gamboa community. I met with Mulget Amaru. Yes that is right. It is the man who is running from Patagonia all the way to Alaska. Because of the pandemic his journey was being put on hold, and he stranded in Gamboa. He has told me some amazing stories about his adventures across the Americas, and he has taught me wonderful things about his home country Ethiopia. Next, Patricia and Yoel, besides being my neighbours and landlords, are two amazing artists which excel in different artistic disciplines such as piano, theatre and visual art. I have had some lovely talks with them over coffee and I hope there will be many more to come. Patricia and Yoel also brought me in contact with Grace. Grace is a writer and a poet. She writes amazing poetry based on her sharp and detailed scientific observations. I also came to know that her husband was Ray Solomonoff, one of the founding fathers of the field of Artificial Intelligence, which is so cool! Unfortunately, she was leaving in a few days since I met her, but she really has inspired me with her poetry and the amount of wisdom that she has. So, putting that in my back pocket for the future 🙂

Of course there was also lots of time to have fun in the past three weeks. I have been to a music festival, organised a potluck dinner party, went on a trip to Boquete and climbed Volcan Barú, sneaked up on the canopy tower, again had some nice sunset hangouts and ate pizza every week at the local bakery here. The next upcoming month I am going to experiment with Arduino and have lots of fun with it. Can’t wait to tell you more in ‘How to become an amateur biologist 103’!

How To Become An Amateur Biologist 101

Hey everyone!

These past few weeks at Dinalab have just flown by. I have already seen so much amazing flora and fauna, met so many cool and nice people, and learned a lot about laser cutters, 3D-printing and plastic recycling. My first week here was mainly about settling down, exploring Gamboa and meeting the community. I went on my first hikes in the jungle and I also got to be acquainted with Teri, the plastic version of cookie monster and learned about p2 and p5 plastic. 

In my second week I started exploring and reading about the framework that is the basis of my project here, namely Umwelt. This concept concerns the subjective realities/worlds of other organisms. Every organisms’ world is constructed on the basis of its sensory perceptions and how they interact with their environment. In simpler worlds, I am interested in how other animals and organisms see, or rather experience, the(ir) world(s) and what these worlds look like. I hope to get a better idea of these worlds by studying and experimenting with them, and hopefully be able to create an output where people can experience these worlds themselves.

During this week, I also started volunteering at APPC and met Valencia the taipir, Lupe the nyeke, Lucy and Lucio the spider monkeys, Marco Antonio the tortoise and dozens of cute sloths. Furthermore, we went to the Mola museum, organised a bike repair with Andy, photographed and modelled for Chelsea’s cute selfmade earrings and had some nice sunset hangouts 😊

The third week was more about creating a plan for my project for the upcoming weeks and months. Together with Andy we created a plan and I filled in some form for my programme in Leiden. Andy and I started putting together the plastic extruder, went on a cool night hike and as icing on the cake I went to Coiba and Santa Catalina with lovely people from STRI.

In the fourth week, I started experimenting and studying my first organism in questions, the Leafcutter Ant. I learned about their pheromone trails, for example how they can be manipulated (😈) and that they can (at least) reach to 70 meters (🤯). Also it was interesting to see how well-organised the trails look from above, but when you start zooming in you see how every ant doesn’t really know what its doing; what a relief, they are just like us 😜. 99% of the time the ants will bump into each other, walk one way and then from one moment to the next the other way and they will carry leaves that are way too heavy which are dropped multiple times on the way. Fun fact: they also like chiliflakes and garlic.

This week I am learning more about bats and agouti’s, stay tuned!
