The growth of human populations and destruction of forest habitat are bringing people and wildlife into increasing contact. What will this collision mean for wildlife, ecosystems and public health? I'm a Duke University graduate student working in Madagascar to measure the health of lemurs at the edge of human encroachment. I hope my research contributes to policy decisions concerning conservation, public health and development.

It seems as though there are new Microcebus species popping up every week….what once had been defined as an eastern and a western species now has been amended to include several species. This has caused some ongoing controversy as scientists debate which species should be considered separate and which should not. But the DNA will tell the tale—that’s why we’re sure to collect small samples of skin to use for genetic analyses. In addition to this data, we’re also noting all the variations in color and size that we see in the mouse lemurs. Armed with this combination of information, we hope to figure out the complex mystery that is mouse lemur speciation in
To counteract the gloomy message of the last entry, I’m going to share with you some great news. Within the last year, the Malagasy government and its park management agency, Association Nationale pour la Gestion des Aires Protégées (ANGAP), decided to expand the size of
Mouse lemurs aren’t the only animals that I’m concerned about out here. Expanding human populations, which push the boundary into preserved areas for resource extraction, hunting, subsistence agriculture and cattle grazing, could lead to potentially huge impacts on the conservation and health of wildlife populations. Where humans go, their domesticated animals typically follow, and where domestic animals go, their parasites are sure to tag along. We can simply look to human history to see the implications of animal domestication. One of the major transitions in lifestyle occurred about 10,000 years ago as agriculture developed. By producing our own food and domesticating animals, humans were able to rapidly increase their populations, and began to live in denser aggregations like towns and cities. This increased density, along with the mixing of multiple species (humans and livestock) in a small area lead to an upsurgence of disease. Over 600 known parasites occur in domesticated animals, and over 60% of the over1400 parasites found in humans have come from a domestic animal origin. To make matters worse, all of these densely packed people and livestock attract another player into this equation—rodents. And as we all have learned from the 14th century’s Black Death, rodents are exceptional couriers of disease. Unfortunately, all of these issues are important to consider for conservation in
Lepilemurs sneak into my dreams at night. It’s not hard, what with their loud, Iwok-sounding calls back and forth filling the forest night air. These nocturnal “sportive” lemurs are a delight to experience. As I brush my teeth, I shine my headlamp through the tops of the trees, looking for their distinctive marble-sized eyes staring back at me. They rest in hollows of trees during the day, saving up their energy to generate an auditory spectacle at night. I have other visitors at night as well—the legendary and elusive Fossa (Cryptoprocta ferox) comes by my tent at night every few days. A pair of them roams the camp looking for water and goodies, and they also have an insatiable curiosity. They will paw through my campsite at night, poking my tent just to figure out what it is. I sit bolt upright in my sleeping bag, thinking about the sheer millimeter of tent material that separates me from Madagascar’s largest carnivore…..But when my headlamp comes on and I give the tent a shake, the fossas are out of there. Or at least that’s what I keep hoping. Keeps you on your toes.
And an update: Well, the fossa did not stay quite so docile this time. Apparently he likes my shoes, or my feet smell like lemurs, because he chewed some nice chunks out of my sandals. A good souvenier story, right?
Get off the road--I even got to try my hand at navigating for a while!
And at the end of the day, a scientist has to be satisfied with the seemingly small specimen bags and tubes that she or he will go home with. It doesn’t look like a whole lot, but the amount of information stored in those small packages will hopefully be interesting and worthwhile.

With just a little encouragement out of the bag, the mouse lemurs are springing forth back into their familiar trees, ready for a night of activity. Check out the release of one of our mouse lemurs at Betampona…….
09I certainly got lucky this summer—a Peace Corps volunteer who’s working in Madagascar emailed me out of the blue to see if I could use some help with my field work. She’s teaching English in a small village east of Morondova and had some flexibility in her summer schedule. I wasn’t quite sure what an English major (Duke graduate no less!) would think about all this tromping through the woods, chasing small primates. But she’s been fantastic—a huge help and a saving grace for my mental stability in the field. We’ll look forward to an entry from her later on this summer—she’ll tell us in her own words what it’s like to work with an ecologist in the field. But to tide us over until then, here’s a little video introduction……
You can get a lot of information from a capture, so we really try to maximize the time that the mouse lemur has so generously donated to us. One of the samples that we take is a small cut of hair to evaluate long-term environmental stress. This is a fairly new technique in hormone analysis that will hopefully be able to show us the residual stress hormone levels (glucocorticoids) in the mouse lemur’s body over a long period of time. In many previous studies, researchers have successfully evaluated stress hormone levels in fecal or blood samples, which provide a picture of stress from the previous day or hours, respectively, but with hair one can evaluate stress on a longer scale, on the time frame of several months. That’s what I’m really interested in—how long-term environmental stress affects wildlife and may compromise their ability to deal with human exposure and increased rates of parasitism.
That’s right, I’m taking the temperature….of one of the smallest primates on earth. It’s important to monitor how the mouse lemurs are doing during the evaluation, and it’s also quite interesting to see how their body temperatures range, especially since mouse lemurs are capable of daily torpor during the colder winter season. We’ve seen body temperatures that range from 92.7° to 98.7° Fahrenheit so far.
Mouse lemurs come in two personality types when it comes to extracting them from the trap. Either they curl themselves into a very small ball in the corner of the trap, or they attempt a bold leap out of the trap and then make a hasty rush for the corner of the tent. Either way they’re pretty amusing to work with, but are quite cooperative patients once we get them in hand.
Or shake hands with a potentially toxic millipede.
We live on the boundary of the Betampona reserve in the small village of Rendrirendry, which consists of 10 to 15 huts mostly inhabited by the Betampona conservation agents and their families. We experience all of the charming and less charming qualities of village life in Madagascar—the spunky Malagasy kids in the village are definitely a plus. They tend to burst into giggles every time they see us (aka the “vazaha be”, or “big white person”) walking around in our ridiculous outfits. My least favorite aspect of village life is the resident group of roosters who crow at 2, 3, 4, and 5 AM (for practice) and then at sunrise (for good measure).
Not only fashion, but function as well. Now introducing the field work/hiking/catching mouse lemurs/slipping down muddy hills/dodging leaches/ new summer line. Socks and mud included.
There are certain reasons why this preserve has remained more or less intact thus far. The diligent presence of its conservation agents makes a difference, and the watchful eye of the Madagascar Fauna Group certainly plays a role. But there’s another reason why large primary forest trees remain here. It’s steep. Really steep. Every morning we huff and puff up the first 2 kilometers out of camp, a trail that brings us up the steep ridgeside to the rolling ridgetop skirted by the main trail in the preserve, Piste Principal. Whew. Who ever said you didn’t get a work out with field work? Check it out….
Check out the resourceful porters carrying our beast-sized bags…they will most likely still beat us up the slippery mountainside. In flip flops no less.
Just in case you were getting bored with me, there’s a new character to introduce into this story—I’ve been joined recently by my Malagasy counterpart, a master’s student in the Department of Primatology and Biological Anthropology at the University of Tana, Herman Andry Rafalinirina. The Malagasy Ministry of Water and Forests and the park management agency, ANGAP, have devised a system whereby all foreign researchers are assigned to sponsor and mentor a Malagasy student from a relevant department at the university. For the duration of the research project and on into the future, I will be working with Herman to develop his master’s project, analyze his data and help him with revisions on his thesis. (Hey, wait a second, did I just get signed up to work on a second dissertation?!) It’s a system that aims to train a huge number of young Malagasy environmental professionals, who learn methodology and project management from their mentors (you mean me??) Obviously you can tell that this is all new to me—we’re figuring it out as we go along. So far things have been going well. After several discussions, Herman will be working on a project separate but complementary to mine. He’ll be comparing water content and characteristics of fecal specimens from Microcebus species on both the west and east coasts. More fecal!
We’ll be on the east coast for the next month or so, continuing to trap Microcebus and evaluate human influence on parks out here in the rainforest. First stop is Parc Ivoloina, a small reserve (~ 400 hectares) privately managed by the Madagascar Fauna Group (MFG), a consortium of conservation organizations, institutions and zoos that share a common mission of conservation in Madagascar. Ivoloina serves as an important park for public education—almost 14,000 visitors and Malagasy students a year come to Ivoloina to see lemurs up close (they have both captive and free-ranging lemurs here) as well as to learn about environmental issues in Madagascar. Additionally, MFG runs training programs for Malagasy environmental professionals, sponsors an agro-forestry demonstration station, and runs a captive breeding program. I visited this reserve last summer as well, where we were able to capture and do health evaluations on almost all of the free-ranging lemurs in the park. We’ll be attempting to repeat that again this year, targeting the Eulemur coronatus, E. rubriventer and E. albifrons, in addition to our ongoing Microcebus capture. Because the free-ranging lemurs in the park are fairly habituated to the human visitors and staff, it’s slightly easier to capture them. We use an effective capture cage system designed by one of the staff members here; the cage can be suspended from a tree and has a trap door that can be closed remotely. When lemurs enter the cage for the fruit and vegetables inside, we can then enclose them and extract them easily. Voila!
I had another reason to visit the Analamazaotra Special Reserve and the nearby village of Andasibe—a colleague of mine worked with a Malagasy guide for her dissertation research here over 15 years ago. She’s maintained a friendship with this guide and has been worried about his troublesome health. She asked me to try and find him in the village this summer, find out about his health, and present him with a letter (Malagasy postal system is a little less than reliable). She promised that the village was small, that everyone would know this particular man—but of course I did have some skepticism. How would I actually find this guy? But I shouldn’t have had any worries—within minutes of entering the village and asking one person, we had Ndrina on the phone and set up a meeting for later that night. It was great fun to meet him and spend the next day with him in the park. And it was a good thing I had him with me--his experienced eyes spotted a recent indri baby for me to see. Think cuddly.
Check out a sneak-peek into everyday life in the village of Andasibe.
Because Analamazaotra receives so many visitors, Malagasy and foreigners alike, it’s a very interesting park to examine for issues of lemur health. I plan on coming back here next spring to capture indri with Dr. Randy Junge, the Director of Animal Health at the St. Louis Zoo, and also one of the founders of the Prosimian Biomedical Survey Project. Much of my data will contribute to this larger dataset of lemur health evaluations—over the last 6 years 450 lemurs have been included in this project. I spent a few days in the park exploring the trails and the infrastructure as a bit of reconnaissance.
One couldn’t get around Madagascar without another of the quintessential Malagasy public transportation systems-- the taxi-brousse or “bush taxi.” They can take you most places you want to go in Madagascar—as long as you don’t mind going with at least 20 other people (and/or chickens, ducks, or sacks of rice) in the small mini-van. The taxi-brousse will be my mode of transport between the east and west coasts, mostly because it’s pretty convenient and it’s darn cheap. Instead of a $400 flight from coast to coast, I can make it from Morondova to Tamatave for about 50,000 Ariary, or $30. What you gain in savings, though, you lose in time--the trip takes 20 hours from Morondova to Tana and another 7 hours from Tana to Tamatave. But it’s all part of the adventure, right?
I thought you would like to learn a little more about these guys from an expert in the field of sifaka social behavior. Dr. Rebecca Lewis is an Assistant Professor in the Anthropology Department at UT-Austin, and has studied these sifaka more than anyone else I know. She knows virtually every individual in the 8 groups here in Kirindy Mitea by name, by birth, by family tree, by personality and by hairdo (Titan has a fuzzy Elvis look to him). She’s been generous to share with us how she and her team go about collecting their data….
…..when it comes to trapping mouse lemurs. I’ve been setting out the traps for the last week or so with some success. We place the traps in their designated treatment areas around dusk, so as to avoid a lot of time when non-target animals (i.e. anything other than a mouse lemur) can interfere with the trap. It’s the alluring smell of banana that brings them into the trap--mouse lemurs LOVE bananas (as do field researchers craving fruit.) Every morning around 7 am we go out and check each trap to see if it was successful. Often we have a trail of ants instead of a mouse lemur, but there are those fantastic moments of peeking into the trap door and seeing those big ears and big eyes starting out at you.
The nights have been cold and long, and the mouse lemurs are staying indoors (i.e. tree holes and nests). That’s my theory for why our capture numbers haven’t been off the charts thus far during this first week of trapping. It’s been interesting seeing where they have been—definitely more so in the pristine corners of the grid system, as would be expected. With warmer weather moving in, we’re keeping our fingers crossed for mouse lemur extravaganza.
In honor of
To test out methodology I set out 10 traps a few nights ago, and had some success on the first day! Meet our first subject, KM 001. A cute little guy, if I do say so myself.
A mere 6 days after I left North Carolina…and I arrive at my destination, Kirindy Mitea National Park. A glorious arrival. I was greeted by Dr. Rebecca Lewis, the founder of the research station here, and researcher on sifaka social behavior from the University of Texas-Austin. She’s worked in Madagascar for several years now, but only recently began working in this park. Starting a new research station means a lot of work and a lot of waiting—for permits, for water, for the process to work its way through the Malagasy system. With a lot of patience, she just recently established the gridded trail system and infrastructure for research at Kirindy Mitea. She gave me a tour of my new home, which is comfortable and beautiful, but didn’t take long to tour……see for yourself!
The camp is a colorful, friendly mix of researchers, camp staff, and a Malagasy student, which means 3 languages may be spoken at any one time (Malagasy, French, or English, in that order of frequency). We all eat our meals together, which generally consist of rice with roasted peanuts for breakfast, rice and beans for lunch, and rice and beans for dinner. We try to spice things up a bit and throw in a few new flavors every once in a while. The grated parmesan cheese I brought from the US was a hit, although it was met with some skepticism at first. You mean…….cheese……….as a powder? After some inspection and a little smelling, the staff tasted it. “Tsara,” they replied, which means “good” in Malagasy!

Of course, if this 4x4 thing doesn’t work out, I always have another option for transportation.
Introduce: The charrette, the local transportation of choice.
Getting to Kirindy Mitea National Park is no easy feat—in fact, it’s virtually impossible by road for most of the year. Over the 70 or so miles from Morondova, there are several river and water hole crossings only passable in the dry season. Be careful if you try a bit too early—your car may wash downstream into the Mozambique Channel. Visitors and researchers will often take a motorized pirogue (wooden canoe) down to a coastal town, Belo-sur-Mer, and then walk to the park. We’ll try that later this summer, but for now we’re cruising in the 4x4.
I’m excited to reach Kirindy Mitea and see what it will be like—I’ve spent many months wondering about this moment. Onward to the river!
Greetings from Morondova, gateway to the Baobabs! I flew in yesterday morning early on a small D60 plane, with propellers and all. There wasn’t a safety presentation, but needless to say, for once in my life I read through the safety card thoroughly, cover to cover. But all was well, even when the pilot got the plane steadied at our cruising altitude and started reading the daily paper. Such is life here….
I love Morondova—it’s a bustling, friendly town on the shores of the Mozambique Channel, a mere 300-400 kilometers from the African continent. I head down to Nosy Kely, the strip of land that juts out into the channel for dinners, where I can watch the sunset on the beach, eat lots of fresh seafood, and sip Malagasy rum flavored with lychee (there are perks to fieldwork). I watched a local woman come into a restaurant last night carrying freshly caught langostines, or lobsters. They were gorgeous, with bright blue, yellow and red coloring.
I’m getting all my supplies (i.e., toilet paper and chocolate) ready to head out for my first stint of field work. I’ll be in Kirindy Mitea National Park from tomorrow until the 4th of July, with a possible break on the 25th and 26th of June to come back to Morondova to take part in Madagascar’s Independence day festivities. I’m sure it will be a party! I’ll send stories from the field when I get back….wish me luck with the ol’ mouse lemurs.
