Science and Culture


Hola from Isla Santa Cruz!

Nugget of knowledge for the day – The Galapagos, early in its history, harbored its very own Robinson Crusoe. He was an Irishman by the name of Patrick Watkins. Thought to have been marooned in 1807 on Isla Floreana by his crewmembers, he spent the next two years on the island surviving, growing vegetables, and trading those vegetables to whalers for rum. In 1809, he hijacked a longboat from a whaling ship, and with 5 prisoners, set sail for the Ecuadorian mainland. Only Watkins reached the mainland alive.

I’m sorry for the delay in updating this blog with a new post. For the past two days, I’ve spent more time in a particular room in our cabin than I have in quite some time, from which I am left exhausted, dehydrated, and frustrated. Today is the first day in which my progress in getting through this is actually visible; I’m taking full advantage of it by…staying here at the research center. My contributions to the research will be much more valuable on Wednesday, so I’m taking today off, spending the day doing all I can to rid myself of whatever microscopic invader is ailing me. Trying to look at the brighter side of things, I have had the great pleasure of watching birds, insects, lizards, and more visit my room throughout the day. In particular, I can happily say that worse things have woken me up than a Mockingbird watching me sleep while perched upon my bare foot.

which looks arguably, just like
me over these past few days.
In addition to catching up on my sleep, being confined to the science cabins at the Charles Darwin Fundacion has also allowed me to become more aware of my limited surroundings, which has, consequently, taught me that my surroundings are not as limited as I thought. As field researchers, we’ve spent a lot of time focusing on techniques, time, and potential for conflict as we progress through our project. Sitting here has opened my eyes to the idea that this space is much more than just a bedroom, but is also a temporary space for life that spans across different kingdoms, and I am merely a part of the party – now where did that gecko travel off to?

When a group of scientists travels abroad for research, they may become immersed in a different and sometimes distinctive, new culture. Whether scientists are conducting that research inside or outside of their home country, chances are high that they will experience new people, new ways of thinking, and new ways of being. Time may be different than what they’re used to, as may be the sense of urgency. The food, hospitality, manners, language, customs, and values may be different. The environment, ecosystems, wildlife, plant life, and trends in biotic and abiotic factors may also be different. Even the final location for where you put your used toilet paper may be different! As guests and temporary residents in the Galapagos, we’ve experienced these differences and much more, all while adapting to, and learning about, the culture along the way. Be flexible and willing to compromise – this has been the mantra we’ve learned from the start. Trying to understand scientific relationships is virtually impossible without building relationships with locals and the powers that govern the area. For you as learning scientists and for us as researchers, this is a critical lesson to remember, especially since not everything will always go as smoothly as planned.

Locals – The Good, The Bad, and the Hilarious
Locals in front of a tienda
on Isla Isabela.
In addition to conducting field research, we’ve travelled from many locations on the island of Santa Cruz to different locations on several other islands in search of our field sites. We’ve had to go into local towns to get groceries, eat dinner, explore the countryside, and connect to the Internet. We’ve needed to acquire fresh water, do our laundry, ask, “donde esta el baño?” (a paramount question in any language) and get money to pay for most of the aforementioned. To succeed, we’ve had to speak with many of the locals in Spanish, a language that is not native or fluent to any of us. We’ve had to put a lot of time into learning how to speak Spanish more efficiently, and have all made progress in talking to the locals one-on-one in a language with which we’re not familiar. This is all part of traveling and conducting science in a foreign country!

Relocated field work.
Marine iguanas in our hostel room! 
Although we’ve had mostly positive experiences here, we’ve also had a select few negative experiences with local human and non-human populations. On the whole, most people here have been extraordinarily kind to us. However, while some treat us just as they do the locals, others have made sure to add an extra “tax” onto the price of our food and groceries. While some people have been very willing to pick us up in a cab, others have looked at us and sped off in the other direction. In some restaurants, we’ve been given delicious, filling dinners as cheap as $3.00, yet have also been immediately charged $9.00 for two accidentally broken containers of olives. And just as some people have supported our ability to conduct research, others weren’t fond of allowing us to be seen by tourists or locals, and required us to relocate quickly at the expense of our research. As guests here in the Galapagos, we must push to understand that, at its core, the differences in cultural normality from our own is driving these discrepancies, and we must accept and navigate those differences.

Dr. Susannah French, and one
of the many cabs we've taken
throughout our travels.
Just as certain people have been at odds with their acceptance of us, the local groups of wildlife have done just the same. We’ve interacted with sea lions as they’ve relaxed on the docks and swam in the water – cute and cuddly, they say! – yet, we’ve also met one particular adult male who adamantly chased members of our team across the beach away from his territory (a lesson learned to always have my camera ready…). We’ve had most of the marine iguanas go through the sampling process without any problems, while one may still be laughing with her friends about the chunk of skin she removed from my thumb. We’ve watched beautiful birds flying overhead and fluttering in front of us, while we’ve also narrowly dodged an attempted drive-by pooping by a local lava gull.
All in a day’s…what day is now?...work in field research.

Tiendas
Typical meal on the Galapagos.
Rice, meat (octopus shown here),
and a small selection of veggies. 
When travelling around to different towns, it’s difficult not to think about the United States and all the things we’ve become accustomed to. Each town supports different stores (tiendas), which are roughly the size of one large aisle in any major grocery store. Since the Galapagos is an archipelago 600 miles off the mainland, everything must be shipped in, grown locally, or caught locally; because of this, there isn’t a vast selection of goods from which we can choose. There are no Walmarts, there are no Targets, and there aren’t any malls. The population, however, continues to grow. With the surrounding area designated as a National Park, the increasing population on the islands will eventually conflict with a lack of space designated by the government for people to live. As a result, most of the tiendas we’ve seen look to be small, family owned shops and are no larger than the size of an average school classroom. 

Buenas noches from the Galapagos.
Most stores don’t sell bread, but instead, there is a bread shop for that (panaderia). Most stores don’t sell much fruit or vegetable products; you must head to the frutateria to find a decent selection. If you want seafood, walk no further than the heart of the port (puerto) to find fresh-caught local tuna, whitefish, and more. And if you want a homemade meal with soup (sopa), juice (jugo), meat (carne), and rice (arroz), walk a few paces farther to the kioskos that serve meriendas and cenas (different variations of homemade dinner) at very affordable prices. All these places with all this character seem to be very normal here, and we couldn’t be happier experiencing it. In addition to conducting our research, we are also living here for an extended period of time, and therefore must learn to navigate and acquire necessities and amenities that can sustain us throughout our trip, all in a culture that is vastly different from our own. Field research in a foreign country is an exciting component of science, yet it is still only a portion of the entire experience!

Final Words
I believe that science has a great capacity to change our existence for the better (as it has already done). Yet at the same time, we must be sensitive to other cultures and parts of the world who may value science differently than we do. What we may think is rational in thought, may be intrusive and culturally insensitive to others. For us to be successful patrons of better understanding our world, I believe we should support educational outreach, well-formed arguments and open conversation, as well as critical thinking and radical openness; these are all ingredients that compose great scientists. As learning scientists, challenge yourselves to really think about these points and push yourself to generate meaningful and rich explanations of what makes a good scientist in your eyes.

I hope you're all enjoying the week! As always, keep your insightful comments flowing!

    1. We are collecting data at a number of different locations. Since we're looking at the effects of tourism, we have sites that have heavy people traffic, and also pristine sites so we can compare the two together. We also have sites on different islands, which creates replicates (instead of just looking at 1 island, we're looking at 3), and also allows us to compare the islands to each other.

  2. What are some major differences and similarities that you've noticed between our culture and the native peoples' culture on the Galapagos islands?

    Replies
    1. This is a great question! Ecuadorian people seem to be very family oriented and enjoy each others' company. Not that this is particularly different from the many cultures in the United States, but it is just something that really stands out to me. They are very hard working, yet the importance of time isn't the same here as it is back home. That component in particular seems to be the biggest different I've noticed; Ecuador lacks the feeling of "time is money and being on time is important", as well as the "go, go, go" attitude that we have in the states.

  3. It looks like they have a lot of different culture than we do! That would be a way cool experience, how has it been with the language change? have you had to learn some things or do you just talk to people with your same language?

    1. They really do! It's been a great experience indeed. Since not everyone speaks english here, we've had to work on speaking spanish to the best of our ability. From what I've noticed in my worldly travels, people in foreign countries seem to respect you and your questions much more if you try to speak their native language. Imagine a foreign traveler walking up to you in the United States and talking to you in a language you don't understand - that would be really really challenging. But if that person were to work at trying to communicate a little in English beforehand, that interaction would go much more smoothly. It's really amazing what common ground you can reach when speaking two different languages. Work hard enough at it, and you will both end up on the same page!

  4. I read somewhere that there are penguins in the Galapagos. Is that true? Do they interact with the Marine Iguanas?

    ReplyDelete
    Replies
    1. There are penguins on only two of the islands here. Since there are marine iguanas on almost every island, I have no doubt that they interact at least on some level! I'm not very sure of this relationship, but it would be a great thing for us both to look into further.

  5. How does the behavior of the marine iguanas differ when they are not around the tourism industry vs. when they are around tourists???

    ReplyDelete
    Replies
    1. Great question! They actually behave very, very differently. The iguanas at the non-tourist sites scatter and run more quickly when approached. Since they're not used to seeing humans there, they may see us as a threat. Whereas here, on the islands that see a lot of human traffic, you can walk right past them before they move. This is my best educated guess about this...do you have any other ideas?

  6. So is most of the food where you're staying at locally grown?And is it imported to other places or countries too? It's just really different looking at the picture of a typical meal and seeing things like octopus being eaten so casually. Also I think that the topic of the satellite males is very interesting-do they ever get in fights or get killed by the other male iguanas? And how are they treated when all the iguanas are in a group together? I'd also just like to say thanks for talking to our class(es) about all the research you've done-that was awesome!
    We all hope you get feeling better soon!

    ReplyDelete
    Replies
    1. Lots of great questions!
      1.) Yes most of the food is locally grown or caught. They do import a fair amount as well.
      2.) Since the islands are so small, most (I think) of what is grown/caught here stays here to feed the people here. Mainland Ecuador, on the other hand, is different - they export quite a few products.
      3.) Satellite males are very interesting, aren't they! We have seen them being chased off by the larger males. Because of the size difference, I'm not sure how well they would fare in a fight against a big guy - probably not well. I would think they would run before being killed.
      4.) Since the satellite males look very much like females, some may go unnoticed, while others may stay on the outside of the population so they don't get run off by the bigger males.
      5.) You're very welcome! I'm happy to do it and thanks for being such awesome students!

  7. Hello from the Cache Valley! In your post you said that you focus on potential for conflict. How come? And have any of the conflicts you thought could go wrong actually gone wrong? Hope all if going well. The lizards are not exactly what I thought they would look like! A little rough around the edges!!!

    1. Hello! We focus on the potential for conflict because, since we're only here for a limited amount of time, and are on a very expensive trip (both in terms of money and time), we want to make sure to limit conflict and things that can stall our research. We want to make sure things run as smoothly as possible for the research specimens, us, the park service, and anyone else who may become potentially involved. And we plan for everything to go a certain way, but for us, this has definitely not been the case, and we've had to learn to work around it! And they are great animals! They really do look incredible.

  9. Question I know from when I go to some place that has lots of tourism you see lots of trash laying around some of the trash is food and like on the beach I can see seagulls eating someones leftover pizza. I can't help but wonder do the Iguanas run into trash from the tourists? How does it affect them? Do they eat it? And what do they usually eat?

    ReplyDelete
    Replies
    1. I'm sure they do run into trash. There are plenty of trash items that wash up on the shoreline, and we've seen far more than we would like. I'm not exactly sure how they interact with the litter and trash that we've seen - I would imagine that it depends on the item. We have seen washed up rafts on the shorelines with iguanas under them. I would imagine that they wouldn't eat it since they are algae specialists, but I think that if there was a large piece of trash with a lot algae on it, they may consider going for the algae not knowing the difference. Great questions!

  10. How bad does an Iguana bite hurt? It sounds like it hurt a ton! What new results have you found? I think that it would make sense that tourism is effecting iguana's attitudes and other stuff like that, I am intrested to learn more.

    ReplyDelete
    Replies
    1. Just like anything with teeth, it can really hurt! The larger the males, the more muscle with they can bite. I've only experienced it once, and hopefully won't have to again.

      As far as results go, we will really get to the heart of this portion of the research when we get back to the United States. Since we're looking at hormones, we have to analyze the blood using specific assays (tests) and machines that can help us with these processes. For the egg counts, we must look at the numbers when we get back by typing them in electronically and analyzing the data this way. We'll look for trends in tourist vs. non-tourist sites, and between the islands. For the wound healing portion, we have to use a specific computer program to analyze how much of the wound has healed, and again compare this data afterwards with tourist vs. non-tourists sites, and between islands. We'll look at differences between sex, differences in time of capture, amount of blood taken, and much, much more. This is a critical portion of the research, but it always comes after the field work. While in the field, we want to make sure to stay as objective as possible, and therefore don't want to assume there is anything positive, negative, or neutral happening with the populations. This keeps us from instilling any bias into our research or sampling! When we analyze the data afterwards, this is when we start to look at statistical trends and any patterns we may see. Then we can really start to address whether or not there are any impacts of tourism on the marine iguana populations!

  11. Hello Mr. K, before you left for the Galapagos Islands did you do any special training or anything to ensure that you would be able to handle the marine iguanas and not harm them?

    ReplyDelete
    Replies
    1. Great question! Since I received my undergraduate training in biological sciences, and have a particular interest in herpetology (study of reptiles and amphibians), I have had much experience handing reptiles in the wild. I've also worked at pet stores in the past, and have owned reptiles and amphibians as pets. You could call all of this my "training" beforehand! I did not receive anything specific to my work with the iguanas, but we did do a lot of planning before heading into the field.

  12. Do the iguanas ever get in fights? An I saw how you marked the iguanas. Do you think that it hurts them to be tagged with the beads? And if you couldn't tag them that way how else would you tag them? Also just a random question, what is the native language there? And what is the average temperature there? Seems very warm.

    ReplyDelete
    Replies
    1. They do get in fights, and some can get pretty rough. We've captured some videos of them fighting that I'll upload and share, and it isn't pretty! But for them, it's necessary. I would imagine that they feel a little poke, but I wouldn't say that it hurts them. Most of them barely react when the beads are attached. They're attached right underneath the spines in a skinny, tough part of the skin. They are also tough animals, as we've seen some walking around without legs, huge scars, and terrible wounds. Other scientists have branded them with liquid nitrogen to keep track of them (which seems a bit extreme for me...), but for long-term identification, it really works. Short term, we use markers that eventually wash off.

      The native language here is spanish and the average temp has been 80 degrees! It's been perfect!

  13. I wonder how the towns and/or cities are like... I doubt there are any similar to New York, but I'm curious as to what they're like, and how people live their lives in these places. Are the towns/cites usually clean? Do much wildlife roam through them? And I'm also curious as to how your research is coming along... Have you found any major results, or do you still need to collect more data?
    Are you feeling any better?

    Replies
    1. Hello! The areas in the Galapagos are far from anything in New York. Are you from there? It would be far too challenging to describe it in as much detail as you're asking for, but with reading this post and a little experience here yourself, you'll have your answers. However, just like New York, some places are cleaner than others. Wildlife can be found throughout the towns, but the presence of dogs, cats, rats, and introduced ants make it all very difficult for the local wildlife to compete.

      The research is coming along well. We have finished our last day of work, and will be analyzing the data in the months to come.

      As far as results go, we will really get to the heart of this portion of the research when we get back to the United States. Since we're looking at hormones, we have to analyze the blood using specific assays (tests) and machines that can help us with these processes.

    1. I have never been involved in any research on marine iguanas before. However, the accompanying scientists, including the principal investigator, have done research on them before. This project was meant to build upon previously collected data, which will help us get at the heart of our primary objective - to better understand tourism and how it impacts wildlife.

    1. Great question! Trips like this take a lot of planning, as does most field research. We had our sites planned out well in advance where we arrived. However, because not all of our sites had marine iguanas when we arrived, we had to change our plans and find a few new spots. After permission from the park, we arranged for travel to those places and collected data from the marine iguanas. But we plan for as much as we can before we take our trip, in order to spend most of our time collecting data and not worrying about logistics.

  17. It's really amazing that there could be such a diverse amount of wildlife. From sea lions to mockingjay's, as well as penguins and Marine Iguanas! All living alongside humans! Also, this Patrick Watkins guy seems pretty cool. Although, why didn't he just get a ride back with the whalers, since they were apparently nice enough to trade with him?

  19. hey mr K
    so your assistant erik looks just like a eric i know here which is funny. and it sounds like you are learning alot more then how tourism affects the iguana's. i was wondering if the iguana's had any other way to deffend them selves besides biting like poison or ways to hide itself and how have you guys adapted to that?

    ReplyDelete
    Replies
    1. Great question! They don't have poison or anything, but blend very well into their environment. Just like the volcanic rock around them, they are charcoal/black in color. They are very fast when they want to move, and can swim extraordinarily well. They have sharp claws, and are packed with muscle, so it's tough to hang on to them. We've adapted by learning all this firsthand working with the animals, and have had to change our strategies when we capture them, hold them, and work with them. Holding the head a particular way, keep the claws out of the way, and using multiple people for one animal have all been strategies that have helped us out greatly.

  21. What you said about the language change, i think it would be easier to make plans to go somewhere to study these things and find out the language of the locals a couple months before. That way you could prepare in advance the language they speak and have better relationship with the people in your surroundings. I think you would get a lot more out of it, and having the locals help you out more, already knowing the language and using your time to study the iguanas rather than spending your time trying to learn the local language. it would make the time you have to collect this data more productive.

    ReplyDelete
    Replies
    1. I completely agree with you! Let me clarify a bit more. Both Lori and myself have had a bit of background speaking spanish, and worked diligently beforehand to brush up as best we could. We purchased guides and dictionaries to help us learn months in advance. The principal investigator for this project actually took a spanish class before coming here! So we prepared very well beforehand to do exactly what you said - conduct research, and not worry about language as much. But being immersed in a place where the people speak a different language is still challenging since none of us are fluent. We tried the best we could beforehand to learn spanish, but we were far from perfect. And learning a different language is extraordinarily challenging, especially when you're older. It takes lots of time, not just months, to learn. It takes years upon years of talking back and force with native speakers to perfect the language.

    1. Not sure where you got the idea that we have a wide variety of food to cook with, because that's definitely not the case! We've got great restaurants to choose from, but they are limited in number, and grocery stores are also very limited in what they carry. But what they have is great! And research takes time; that particular day, we just didn't have enough time to finish what we needed to do.

People really enjoy each others' company here - very few people have cell phones, and instead of texting others while sitting together, they really talk with each other!

  26. So how many people live on the island? It sounds like there aren't to many, but it sounds like a great place to live! Did you get sick because you were in a new place and not immune to some of the sicknesses they get? How do you catch the iguanas? It sounds pretty difficult to me!

    ReplyDelete
    Replies
    1. There are about 3,000 people that live permanently on the islands. As you mentioned, it's not very many! I got sick here because, as you mentioned, my immune system developed in a place that didn't have many of the pathogens that are found here. We're still not sure where I could have caught from, but all it takes is one bacterial cell or one microorganism to start proliferating! You can get this from the water, the food, or anything you may ingest.

      We catch the iguanas by sneaking up on the and picking them up! On some of the islands, it is very tough, but here where the tourists are found (and they're used to people) it's not that difficult.

    1. The Galapagos has about 3,000 people, and there are only a few major towns. The major towns are port towns, and there are only a few. 97% of the islands are owned by the Galapagos National Park, while 3% are dedicated for people to live.

  29. Will you be doing any other research at all on other animals?

    1. Since marine iguanas are found in large populations both around tourists and in pristine locations, they are a great model organism to study the effects of tourism. They are numerous within their range too. The principal investigator is also a reptile specialist, and has worked on these animals before, so we will only be focusing on these animals.

  30. how many iguanas have you found where you are and how big do they get.

    1. We've seen hundreds! Our final sample count was around 180. Read a bit more in my Natural History blog to get more info on the iguanas.

  31. ...Wow. That was a very thought-provoking post! I'm glad to see that you didn't wallow at the prospect of being confined to your room, and instead used it as an opportunity to view the world (and your research, for that matter) from a new perspective. That's a good way to live your life, and an essential ingredient to an innovative scientist ;) Your words on the differences in culture were especially striking. Coupled with all the mentions of your "limited surroundings" and the habitat of the iguanas, it got me thinking about how the iguanas might be feeling about the growing human population of the Galapagos. From what I've picked up, they don't seem to be showing many physical changes, but have you noticed any subtle changes that might indicate stress or something of that nature?

    1. Thank you for the very kind words and the time you took to post this. It is indeed very difficult to not wallow in sickness, but when you're in the Galapagos, you're in the Galapagos! It is always a "glass is half full" kind of place :) It is absolutely a great way to look at life, and one I enjoy on a daily basis - it sounds like you do too.

      Although a great question, it's tough to discuss how the iguanas may be "feeling". Any sort of inferences on the emotions or feelings of animals will undoubtably have human and personal bias. Ask me, and I would say they are "unhappy", but ask a tour guide whose life revolves around making money through people experiencing marine iguanas, and you may get a very different answer. But as far as I can tell too, there don't seem to be any physical changes (in terms of phenotype, or exterior features). Inside, however, physiologically, their hormone levels are different in areas of high tourism vs. those that don't see people. Iguanas found in tourist locations have higher levels of corticosterone (CORT) than do iguanas in non-tourist areas. They seem to be hypersensitive to stress, and their bodies are releasing more CORT into their bloodstreams after a stressful event. There is evidence to suggest that prolonged responses to stress in this fashion may come at the cost of immune function and reproductive success. We have found that, also, their ability to heal wounds is suppressed at tourist sites vs. non-tourist sites. The data that has been collected so far suggests strongly that chronic exposure to mild stressors (such as ecotourism) is having a negative impact on the marine iguanas, and is causing a physiological change in them as well.

  32. Do the iguanas react better to you when they are alone or by their same species?

  35. the scientist that studys olny the lizards or other animals for the DNA of humans distraction. what would you do when the DNA is positive that its is affecting the lizard and other animals. if it is affecting the iguanas will the scientist keep on going to the island or would they stop and shutdown the labs or tests of that island
