Megophrys nasuta
One of the group asked about Megophrys nasuta after looking it up online--yes, it is SO much like a leaf! And yes, they tend to be found in leafy areas--the forests here have a lot of leaf litter, and when you put them amongst a bunch of it, you can really see how fantastic their camo is. Below are a couple of photos I took the last time I was here in Sabah. Cute, eh?

4 July 2010 Park Headquarters, Kinabalu Park, Sabah, Malaysia
Hey gang,
Amazingly, this is my last week & entry for my time here on Kinabalu. It seems to have gone by so fast! It was a good week to end on--Samantha and I went up towards the summit to survey two high elevation sites: Pakka at about 3120 m, and Kemburongoh at about 2750 m. We stayed about half-way between the two on the summit trail, and hiked up or down, depending on the day.
We started the week surveying the higher sites, and found very few frogs—only a few species get up that high, and they’re not very abundant. The highest elevation we saw a frog was about 3150 m—pretty high!—and the most frogs we saw in a single night around Pakka was three! Because we were staying in a cabin along the summit trail, we got to speak with some hikers about what we were doing, and I enjoyed seeing the surprise on people’s faces when we told them that yes, frogs do occur that high. I love that frogs are always surprising people—they’re so sensitive to environmental change in so many ways, but in many ways they’re very resilient. You can find them in deserts, in frozen ponds (and yes, they will survive), and in brackish water. But if you alter the habitat of a given species, they don’t often fare well. Frogs are extremely sensitive to climate change, habitat alteration, and fungal disease, just to name a few of the threats they currently face. I love this dichotomy about them, and I hope that my work will ultimately contribute to the conservation of this awesome group of organisms.
At both sites we recorded a few individuals to try to determine the differences between a couple of cryptic species. The term “cryptic species” can apply to various types of organisms. It sometimes refers to species that are well camouflaged and difficult to see, and sometimes it refers to multiple species that are difficult to differentiate from one another. Most evolutionary biologists use the term in the latter sense—and in our case, we are trying to determine differences between multiple species of a small tree frog in the genus Philautus. In some cases, you can determine species by elevation (up above 3000 m, there’s mostly saueri and amoenus). In other cases, you can differentiate based on size (some species are bigger than others). However, at Kemburongoh, there are multiple species in the exact same site—so we’re hoping that their calls are significantly different and that we’ll be able to tease them apart that way. I’ll let you know what we find!
Another aspect of this week that I really enjoyed was hiking up and down all over the place—it was really challenging physically, but in a way that leaves you feeling like a million bucks at the end of the day. Mt. Kinabalu is incredibly steep, so the 6 km hike up to our cabin took about 2.5 hours. There are stretches of the trail that consist of high steps (yes, they have built steps out of rock and two-by-fours) for what feels like miles, but is really only a hundred meters or so. And because of the elevation, each step can feel like a real challenge—there were times when I was out of breath just from walking at a slow pace! But by the end of the week, Samantha and I managed to hike the steep 2 km from Kemburongoh to our cabin in about 45 minutes—woohoo! It was definitely a workout, but it felt fantastic, and I’m pleased that we acclimated and started getting used to the amazing workout that is Mt. Kinabalu.
As this week started drawing to its close, I found myself a bit nostalgic—I really do love Sabah, and I have enjoyed my time here immensely. I think my Malay has improved quite a bit, and I’m pleased that I have picked up some Dusun. I’m going to miss being here on Kinabalu, and I hope that I’ll be able to create more projects in the future that involve work on this mountain. I think it’s a spectacular spot for field work—the steep elevation gradient allows you to survey a wide array of environments in a relatively short distance. There are all sorts of ecological and evolutionary questions that can be addressed, and I really love working with the Park staff. I look forward to a long future of collaboration and work here in my Asians home away from home.
On Tuesday I head to KK, then fly back to Singapore on Thursday, and on Friday I’ll be going to the US for a week for my brother’s wedding. I absolutely can’t wait! It will be great to be home and to see friends and family before coming back for my field season in Thailand. My first update from there should be coming your way around the 7th of August—I look forward to catching up with you then!

27 June 2010 Kinabalu Park Headquarters, Sabah, Malaysia
Hi gang!
This week two exciting things happened—call recording and a Sabahan wedding. Cha-ching! I love weddings—and Sabahan weddings are spectacular. But first, the call recording.
We made call recordings for a couple of reasons. One is that we wanted to start a library of call recordings for Kinabalu Park so that future researchers can utilize it as a reference and quickly learn which calls are which. For this we recorded all the species we could get (about 5) at the Miki Survival Camp (about 1000 m elevation).
A quick note about frog calls: they are incredibly varied and in my opinion, spectacular. Some are long trills, some sound like insects, some are loud honks, and others sound like someone is laughing at you. I started doing call recording a few years ago for my dissertation, and it was very different from other frog work I had previously done. Usually my work is about finding as many frogs as possible in a given amount of time, or over a given distance. With call recording, the work is much slower paced and requires a lot of patience. Some frogs will stop calling when you approach, so you have to find one that is calling, then turn off your headlamp and wait for them to start calling again. Sometimes they don’t start up again and you have to move on to another frog after 20 minutes or so. Sometimes they hop away while your headlamp is off, but you don’t know that until you turn your headlamp on again 10-20 minutes later. But when it all comes together, it’s really amazing to hear the call through a microphone—you pick up on so many more subtleties of the call than you do when you just listen normally. Then later when you analyze the calls (using special software) you actually get to SEE the differences in a spectrogram. It’s fantastic.
So we started working on the call library for Kinabalu Park, and we also recorded the call of Leptobrachella baluensis, because Paul (our Sabah Parks counterpart) thinks that this might actually be two species. This species is great because the mature males are only about 15 mm long (!!) and the call is sort of a funny ratchet-y sound. We only recorded about 5 individuals, and we haven’t yet analyzed them, but offhand we think there might be two different calls—which could mean two different species, or huge call variation within a species. Both of which will be interesting and exciting! My other secret reason for wanting to make call recordings is because I’m convinced I can use frog calls to make a cool house music mix, or piece the sounds together so they sound like actual words for a conservation-themed song. In my head, it totally works. =)
Speaking of awesome music, the other highlight of the week was the wedding we went to last night. The younger sister of my former neighbor Rusinin got married, so we were invited to join the festivities. I have been to 3 previous weddings here in Sabah, and I have loved every one of them. There is always dancing, with the Sumazao (the Dusun dance) playing a prominent role, usually there is karaoke (in Malay, Dusun, and English), a set of huge gongs are played, and there is a ton of delicious food. In many cases, a water buffalo (kerbau) is slaughtered for the wedding, and the elder women of the family will make giant wok after giant wok full of kerbau rendang. Rice is made en masse and served from coolers (which ironically work to keep it warm). And if it’s a non-Muslim wedding, local rice wine is passed around. Sabahans are hugely warm and friendly anyways, but at weddings they really shine and I have always been made to feel like a very special guest.
For many Sabahan weddings, there are multiple days of festivities. When I went to Justinah and Rusinin’s wedding many years ago, there was a ceremony at the mosque several days before the day of the wedding party. On the morning of the party, everyone gathers at the groom’s family’s house to eat, drink and socialize. From there, guests proceed in a caravan to the bride’s family’s house. The best part of the caravan is the truck that has the gongs—there are brass gongs in a series of sizes that get played the entire way to the bride’s house. Each gong gets played in a different rhythm, and there are multiple “songs” that can be played. At the bride’s house, the groom and his parents approach the bride and her parents, and when they meet they exchange greetings and blessings and the bride is united with the groom. Then everyone enters the bride’s family house for more food and drink and socializing. Later in the evening, the proper party gets going.
Last night we met up with Justinah and Rusinin in their kampung (village) and walked the few houses down to the wedding party together. The party was held in an open-air area attached to the bride’s parents’ house—a sort of extended patio had been erected from plastic tarpaulin and bamboo just for the wedding, a fantastic example of Sabahan innovation. After being introduced to the parents of the bride and groom, we were directed straight to the food—eggplant sambal, beef rendang, stir-fried veggies, a salad of pineapple, carrot slices, onions, and cucumbers…mmmm…no kerbau this time, but it was all delicious.
The evening progressed into a happy chaos of gong-playing, karaoke, dancing, and much interaction with the mob of kids. Everyone on our team took turns at the gongs;
Samantha, Anne, and I sang “Change the World” by Eric Clapton and “Don’t Cry for Me Argentina” because those were the only English karaoke songs we knew; we all danced the Sumazao many times and we managed to rope nearly every kid in the village into dancing with us.
The kids were probably the highlight of the evening for everyone—they all started out really really shy, and afraid to talk to any of us. But we were able to slowly convince them to dance, which led to some minor conversation, and then later each member of our team was surrounded by about 10 kids each, exchanging funny faces, basic questions in mixed English and Malay, and periodic dancing and singing. I think one of the reasons I like weddings in Sabah is because they remind me of Sheridan weddings—lots of dancing, heaps of kids, and good times all around. I’m looking forward to my brother’s wedding in just 2 weeks! I think this was a good warm-up for me.
Tomorrow morning I leave for my summit camping trip, though I use the term “camping” loosely—we’ll be staying in a cabin, which is lucky, because it will get down close to freezing at night up there. I’m eager to see how high the frogs go, and to try to tease out some cryptic species identifications using frog calls. Stay tuned for the results!

20 June 2010 Miki Survival Camp, Kinabalu Park, Sabah, Malaysia
Hi all,
This week we were finally able to leave for our camping trip. We were supposed to be camping for 9 days, but it ended up being only about 7 due to some crazy weather. Our goal was to survey three sites for three nights each--Miki Camp at about 900 m, Sungei (the Malay word for river) Kinataki at about 1600 m, and Marei Parei at about 1750 m. Each of these elevations, and two of these exact sites, were first surveyed for frogs in 1929, and we're replicating the earlier methods as best we can in order to determine whether abundance and diversity has changed, and whether the elevational distributions of these frogs has shifted with climate change.
We spend out first night at a "survival camp" run by a local fellow, and then camped next to the Sungei Kinataki starting on our 2nd night. Field camps are different everywhere you go, depending on the type of work you're doing. If you're going to be at a site for some time, you might make a sleeping platform (to keep you off of the wet ground) and a covered specimen processing area with a table, in addition to a cooking and dining area. Since we were only going to be there for a few nights and we weren’t going to be making any specimens, we kept our camp pretty simple with a few tents and a tarp-covered cooking/eating area. This particular river valley is very steep, so there isn’t much flat area next to the river—which made finding a tent spot a bit of a challenge. The trail comes almost 150 m straight down into the river on one side (so forget about camping on that side), and on the other side there is about 20 feet of gentle slope before it starts going straight up again. Unfortunately, Samantha (my field assistant) and I weren’t as adept at flattening our tent site as our Malay friends were, so while Paul made himself a level area covered with big soft leaves, almost like a gorilla nest on which to put his tent, Samantha and I hurried to put our tent on semi-level ground and ended up sleeping on various roots and trying to contort our bodies into comfortable positions for three nights. Next time, I’m copying Paul.
The frogging on the Kinataki was quite good, but on the afternoon of the 2nd day there, it started to rain. Around 2pm Samantha and I retired to our tent to try to stay warm and dry, and when we emerged around 4:30 to start our hike up to Marei Parei, the river had become a raging maniac which was threatening to take our kitchen area away from us! Paul (our Sabah Parks counterpart), our guide Maurice, porter Liun, Samantha and I all spent the next hour nervously watching the river inch its way towards our tents. We left Liun to watch the camp and rescue our gear if necessary while the rest of us went up for the survey, and returned several rainy hours later to find the river within about 3 feet of the lowest tent (Paul’s). I have only seen a river in flood a couple of times, and never from such a close, precarious distance. The noise level is astounding—I literally couldn’t hear Samantha speaking to me from 2 feet away if she was using a normal speaking voice. I knew that we weren’t in any real danger and that the worst case scenario would mean packing up our tents and gear in the rain and making camp at Marei Parei which is far outside of the flood plain, but it was nerve-wracking to go into our tent not knowing whether we would be staying the night or making a quick escape. Around midnight the river finally started to subside and I was able to sleep relatively soundly. Or as soundly as I could given the fact that my sleeping bag was wet, I was cold, and there were roots poking me in the back and shoulders. I was definitely happy to return to the Miki Camp a few days later to sleep on a flat sleeping platform!
We have a few more days of this camping trip before heading back to park headquarters. I’m looking forward to doing some call recording this week, and to seeing what other species we can find. Hope you are all well—looking forward to hearing from you!
Cheers,
Jen

13 June 2010 Kinabalu Park Headquarters, Sabah, Malaysia
Hi gang!
What a week! I spent most of this week helping a colleague install pitfall traps. Pitfall traps are one means of sampling amphibians and reptiles, or other fossorial fauna (animals that live in the leaf litter or in the top layers of soil). Sam (my colleague) installed a series of 20 trap lines with three buckets in each line—imagine three buckets sunk into the ground in a relatively straight line, with a tarp suspended vertically between them that is buried slightly in the ground. The idea is that as animals move through the forest, some of them will run into the fence (the tarp) and move along it to try to get around it—then fall into one of the buckets. The traps (buckets) are checked every morning, and it’s a great way to see what is moving around on the forest floor. But it’s a lot of work to install! Sam had to walk up off the trail multiple times for each of the 20 sites, and when he found a good spot, Samantha (my field assistant) and I would follow his bush-whacked trail with our shovels to dig the holes for the buckets (about knee height and the same diameter across) and put up the fence. It would have been easy if it were just soil, but there are always roots to get through and sometimes rock…on top of that, we had to hike in with all of the equipment every day (buckets, huge rolls of tarp, string, and digging equipment), so the three of us are feeling quite strong, if not a bit bruised, blistered, and scratched up from all the rattan! We’re happy to have it all completed, and Sam can now start collecting his data.
The other thing I have been trying to work on this week is my Dusun. The official language of Sabah is Malay, but there are many local languages still widely spoken. Most people who live on and around Mt. Kinabalu speak Dusun—which in itself has several variants. For example, a friend of mine from Kota Belud said that the word for “delicious” is “ami” but another friend from close to Ranau has never heard that and instead uses the word “awasu.” I love the sound of Dusun—there are lots of g’s and k’s and ou’s and it’s really fun to speak. To say good morning, you say “osonong kosuobon” and how are you? is “okuro kuro habar nu?” Yesterday I learned how to say “what is your name?” which is “isai ngaran nu?”
There are a surprising number of ethnic groups in Sabah, all of which have their own language, traditional dress, and distinctive facial features. The Sabah Museum in Kota Kinabalu has a great display of the dress, traditions, locations, and home styles of the major groups, and I try to go every time I’m here to learn a bit more about them. I found out last time that in Kota Belud, which is not a large town, there are three endemic ethnic groups (Bajau, Dusun, and Inarun), as well as various Chinese immigrant groups. Many people thus also speak multiple languages (at a bare minimum, their own local language and Malay)--my friend from Kota Belud speaks eleven! The nice thing is that people here are genuinely happy and surprised when a white person (or “orang putih”) even attempts to speak Malay or Dusun—and they will always help you learn more and encourage you to continue, even if you make mistakes. I find it makes me want to try to learn and speak more every day, because people seem so appreciative. Plus it’s fun learning new languages—it’s sort of like a puzzle that you slowly put together until you’re able to get a pretty complete picture of what’s going on around you.
This week Samantha and I depart for a 9-day camping trip in which we will visit and survey three different elevations. It should be pretty interesting, given that it has been raining almost every day! So that should make the trail pretty slippery and challenging, and make it difficult to stay warm and dry! The things I do for these frogs…
I hope you are all well, and I look forward to getting your questions about Sabah and life in the field!
What a week! I spent most of this week helping a colleague install pitfall traps. Pitfall traps are one means of sampling amphibians and reptiles, or other fossorial fauna (animals that live in the leaf litter or in the top layers of soil). Sam (my colleague) installed a series of 20 trap lines with three buckets in each line—imagine three buckets sunk into the ground in a relatively straight line, with a tarp suspended vertically between them that is buried slightly in the ground. The idea is that as animals move through the forest, some of them will run into the fence (the tarp) and move along it to try to get around it—then fall into one of the buckets. The traps (buckets) are checked every morning, and it’s a great way to see what is moving around on the forest floor. But it’s a lot of work to install! Sam had to walk up off the trail multiple times for each of the 20 sites, and when he found a good spot, Samantha (my field assistant) and I would follow his bush-whacked trail with our shovels to dig the holes for the buckets (about knee height and the same diameter across) and put up the fence. It would have been easy if it were just soil, but there are always roots to get through and sometimes rock…on top of that, we had to hike in with all of the equipment every day (buckets, huge rolls of tarp, string, and digging equipment), so the three of us are feeling quite strong, if not a bit bruised, blistered, and scratched up from all the rattan! We’re happy to have it all completed, and Sam can now start collecting his data.
The other thing I have been trying to work on this week is my Dusun. The official language of Sabah is Malay, but there are many local languages still widely spoken. Most people who live on and around Mt. Kinabalu speak Dusun—which in itself has several variants. For example, a friend of mine from Kota Belud said that the word for “delicious” is “ami” but another friend from close to Ranau has never heard that and instead uses the word “awasu.” I love the sound of Dusun—there are lots of g’s and k’s and ou’s and it’s really fun to speak. To say good morning, you say “osonong kosuobon” and how are you? is “okuro kuro habar nu?” Yesterday I learned how to say “what is your name?” which is “isai ngaran nu?”
There are a surprising number of ethnic groups in Sabah, all of which have their own language, traditional dress, and distinctive facial features. The Sabah Museum in Kota Kinabalu has a great display of the dress, traditions, locations, and home styles of the major groups, and I try to go every time I’m here to learn a bit more about them. I found out last time that in Kota Belud, which is not a large town, there are three endemic ethnic groups (Bajau, Dusun, and Inarun), as well as various Chinese immigrant groups.

6 June 2010 Kinabalu Park Headquarters, Sabah, Malaysian Borneo
Hi gang!
For the next 9 months or so I will be conducting biological field work in some pretty cool places—Mt. Kinabalu in Sabah, central Thailand, Danum Valley in Sabah, and a remote part of southeastern Sarawak. It’s such an amazing job and I felt like I should share it with you. I’ll do my best to write a bit each week to tell you about my work on frogs, the biodiversity in each of the places I work, the various cultures and histories of the areas, the food, and what life is like in the field.
Tonight was our 3rd night of field work, and it marks the end of my first week in Sabah. With field work, there is always some level of administrative hoop-jumping in terms of getting your permits and arranging logistics like renting a field vehicle, finding housing, and sorting out field work schedules. Most researchers will complain about the permitting process in some way (I certainly have!) but in all honesty it’s not that bad—it just takes a long time and requires going to several offices, filling out forms, getting signatures, and repeating that about 10 times—both at the beginning when you submit your application, and at the end when you want to pick up your permit! But I now have permits for every place I will be working, so I’m happy.
The purpose of my project, and the reason I get to go to all of these great places is to survey frogs, in order to determine whether abundance and diversity throughout SE Asia have changed in the past 20-80 years. For the most part, this requires me to go out at night and look for frogs in a standardized way (which allows me to compare my results from each of the different sites). At most of the sites, I will also be conducting diurnal forest plot surveys—we mark off a standardized area and search the entire quadrat for every frog we can find. By doing this over a period of about 2 months at each site, we hope to find the majority of frogs that are at each place. Then we can compare our results with previous surveys in order to determine whether frog populations in SE Asia are declining. Let’s hope not!
Last night was a great night for field work. It was just about to rain when we started our survey, and all the frogs seemed to know it. We saw two species of Megophrys, several Leptobrachium montanum, and a cool Kaloula baluensis that seemed to prefer walking in very very slow motion rather than hopping. I heard him calling so we turned off our lights and waited until we could hear him again. When one of our team switched his headlamp back on, the little frog was crawling very very slowly, as if trying to escape unnoticed! It was super cute and I had to stifle my laughter so as not to disturb him too much. The other cool thing about this species (and all members of this genus) is that they exude a very very sticky substance as a defense mechanism, so when you pick them up to measure them, your hands often get covered in a sort of frog glue. The frogs use it to avoid being eaten by snakes—the snakes often drop the frog because of the mouthful of bad-tasting sticky goop they get. Not a bad way to avoid predation! To top it all off, we heard tarsiers calling throughout the night! I still haven’t seen one, but I haven’t given up hope.
As I’m getting reacquainted with the forest here, I’m reminded of all the great things I love about Sabah and Mt. Kinabalu. The mountain itself is stunning; it is home to the world’s largest moss—Dawsonia, which I love; the variety of birds and frogs and invertebrates is amazing; and the people here are some of the nicest and funniest I have ever met. I’ll do my best to write about all the great things here in the coming weeks, and I look forward to getting your questions! Have a great week, and as we say here, selamat tinggal!

Hello Everyone!
I think it would be better if everyone sent their questions to Lindsey, rather than trying to post them on the blog themselves. If anyone disagrees with this, let me know but I was thinking about having so many people accessing the blog and thought it would be more orderly this way. Any thoughts on this are welcome.
I am going to suggest to Jen that she use the edit feature for each post, go to your question and answer it directly on that post (maybe in another color or something), instead of answering it on another post…it will put the answers and questions together and keep the discussion more orderly. (For those of you who have blogged a lot you know what I mean…if we have a lot of questions posted and pushed down the page, Jen’s answers will be disconnected from the questions)
After Jen answers the questions, I would like the children (and adults for that matter) to write a quick paragraph about what they learned in that session that really impressed them. It will be interesting to see what everyone loves the most and what they learned at the end of each week.
So to recap: 1. We will receive a field report from Jen weekly. (which Lindsey will post)
2. Read the field report
3. Come up with questions for Jen about the report (write out questions and email to Lindsey who will post on blog)
4. Then write what we learned. (and send it to Lindsey who will post again)
5. We hope to set up a skype account or online classroom so that we can actually interact with Jen once a month or so as well!
Any thoughts or questions would be welcomed! This is going to be fun!

Lindsey, here are my two questions for Jen…1.) Are you camping above near the treeline? It is so funny to see the top of the mountain with no snow on it but no vegetation either.
We are not above the treeline, but will be going up there next week (the 28th of June)--still staying below the treeline, but surveying right up to the treeline. We don't think there are any frogs up at the treeline, but we will survey up there to make sure we know how high the frogs go. I agree--coming from North America, it's strange to see high peaks without snow!
2.) I also noticed, in the googled pictures that I saw, that the vegetation on the lower parts of Mt. Kinabalu aren’t as lush as I imagined it. In fact, I have been on hikes near Arlington where the vegetation is lusher and greener. Is it really more sparse on Mt. Kinabalu than in Washington?
There are parts of Kinabalu that are really lush and green, and parts that are dry and sparse. A lot of the mountain is National Park, and so it's protected, but there are some parts of the slopes that are outside of the park. Where it's not protected, most of it has been cleared for settlements, rubber trees (which are subsidized and can bring good income), agriculture, and the like. So it all depends on which part of Kinabalu you're looking at. I'll try to send some pictures of the more lush parts of the forest soon.
Or maybe there is a drier time of the year where the forests aren’t as lush? I know you haven’t seen the pictures I have seen but could you compare the vegetation on Mt. Kinabalu to the vegetation in the rainier parts of Washington?
There are definitely rainy & dry periods which affect how the forest looks here. When it rains it can be really crazy wet. But it can also dry out pretty fast. So it all depends on what the weather has been like lately. The vegetation in WA is mostly evergreen forest with lots of moss. Here, because the mountain spans such a steep elevational gradient (from sea level to 4000 m), you get huge variation in the vegetation. Down below about 800 m, it's what you would think of as lush jungle--huge dipterocarp trees, lots of small vegetation in the undergrowth, some moss, and tons of rattan. As you go up, mosses become more prominent, and above about 2000 m the forest becomes shorter--the trees are stunted (they are about as tall as I am), and you get more pitcher plants (Nepenthes) and mosses. You can also get variation when you have tree falls which create light gaps in the forest--this allows smaller plants to flourish and creates patches of variation in the forest. You will see this in Washington State as well, but the plants in each location (here vs. there) will be very different. I'll try to send some pictures of this in the coming weeks.
