School children with the Madagasikara Voakajy lemur mascot!

At Madagasikara Voakajy we promote conservation, and sustainable use of Madagascar’s unique species, habitats and ecosystems, for the benefits of Malagasy people.

Madagasikara Voakajy was established in 2005 to provide job opportunities for young Malagasy researchers. Over time, we have evolved to become an organization that provides opportunities for Malagasy biologists to become leaders in the conservation and ecological study of a wide variety of species.

Nowadays, we use evidence-based interventions and stakeholder engagement to target our conservation of species and their habitats. Currently, we have teams of experts who focus on baobabs, bats, reptiles, amphibians and lemurs.

How We Protect Lemurs And Other Wildlife

We monitor four species of lemur, having implemented a monitoring program using occupancy modeling, a method that could be implemented easily with the local communities. In the Alaotra-Mangoro region, our interventions benefit at least seven other lemur species.

Hunting for lemurs in the Alaotra-Mangoro Region (where Madagasikara Voakajy does much of its work) is a real problem. Our research on this topic has found that lemur hunting may be widespread in this region and may be increasing. In addition, the traditional taboos that some groups in this region hold against hunting some lemur species (like the Indri) may be breaking down. Since 2015, the monitoring of threats and pressures has been carried out. Only Ayes-ayes now remain taboos for the hunters.

In October 2015, we started using camera traps to monitor lemurs and other animal species in Mangabe protected area (Moramanga district). This method provides valuable information on the presence / absence, behavior and habitat use of lemurs.

What Lemur Species We Protect

Currently, Madagasikara Voakajy directly impacts the following lemur species:

  • Common brown lemur (Eulemur fulvus)
  • Indri (Indri indri)
  • Diademed sifaka (Propithecus diadema)
  • Alaotra gentle lemur (Hapalemur alaotrensis)

How We Support Local Communities

Madagasikara Voakajy

Madagasikara Voakajy has worked to create several protected areas and natural resources use programs in Madagascar.

Outreach

Given the high rates of lemur hunting in our target region, Madagasikara Voakajy undertakes awareness campaigns of the protected status of lemurs with both children and adults. For example, ‘Lenari’, our Indri mascot, interacts with audience members at outreach events through playing, singing and dancing. ‘Lenari’ makes appearances at the organization’s events which include animal festivals, drawing competitions, song and poem competitions, field trips, and even the creation of school biodiversity clubs.

Now, the SOS project, “Youths for lemurs – Lemurs for youths”, sees young people aged 15-25 from the villages around Mangabe, participate in the conservation of lemurs. Young people make song contests, interviews on lemur conservation and broadcast radio programs to raise awareness of the importance of lemurs amongst their communities.

Madagasikara Voakajy

Madagasikara Voakajy trains Malagasy scientists both at the university level and beyond.

Madagasikara Voakajy also undertakes outreach in schools. Our partnership with education authorities at the local level is especially helpful with schools located in communities that are within the boundaries of new protected areas.

Capacity building

Through our student training program, Madagasikara Voakajy continues to nurture the next generation of Malagasy scientists.We are also aiming to build the careers of promising Malagasy biologists through employment within the organization.

Critically endangered mongoose lemur born at LCF in 2014.

The Lemur Conservation Foundation (LCF) helps conserve lemurs through managed breeding programs, outreach, and on-the-ground conservation in northeast Madagascar.

We are a non-profit corporation dedicated to the preservation and conservation of the primates of Madagascar through managed breeding, scientific research, and education. The foundation (and accompanying lemur reserve) focus on fostering natural lemur behavior to encourage a dynamic population.

LCF supports educational programs started by the late Dr. Alison Jolly in Madagascar and is developing content to bring those programs to classrooms in the United States. In addition, LCF provides financial support to assist in the establishment of a tourist and research camp in Anjanaharibe-Sud Special Reserve in northeast Madagascar, home to the elusive Silky Sifaka and a unique population of Indri with black pelage.

How We Protect Lemurs And Other Wildlife

LCF has partnered with the Madagascar National Parks in Anjanaharibe-Sud Special Reserve (ASSR) to provide boundary demarcations for this protected area and a site called Camp Indri which provides base camp for tourists and researchers. This helps protect habitat for lemurs and other wildlife.

Ex-situ we operate a 100 acre reserve in Myakka City, Florida. The reserve is set up with two semi free-ranging forests, each approximately ten acres, and two traditional enclosure buildings. As a Certified Related Facility with the Association of Zoos and Aquariums, LCF participates in the Eulemur Species Survival Plan (SSP), Ruffed Lemur SSP, and Ring-tailed Lemur SSP, which include a global network of institutions working towards the propagation of selected lemur species in order to ensure the healthy existence of those species whose survival is in peril.

LCF also hosts field training programs, in which professors and their students utilize the facility and the lemur colony for behavioral observations and research on social dynamics and cognitive skills, as well as habitat use and food selection. These training programs produce future primatologists and conservation biologists which will carry the conservation imperative forward for lemurs and other endangered species. Fostering and inspiring conservation based careers is an invaluable part of LCF’s mission.

What Lemur Species We Protect

At our reserve in Florida, we house over 45 lemurs of six different species, most of which are critically endangered or endangered. LCF is a Certified Related Facility with the Association of Zoos and Aquariums and participates in their Species Survival Plans which work to maintain a genetic safety net for a variety of lemur species. The species currently at the reserve are:

A family of Lemur catta in one of LCF’s semi free-ranging forests, where field students can observe lemurs in a natural environment.

  • Collared lemur (Eulemur collaris)
  • Mongoose lemur (Eulemur mongoz)
  • Sanford’s lemur (Eulemur sanfordi)
  • Common brown lemur (Eulemur fulvus)
  • Red ruffed lemur (Varecia rubra)
  • Ring-tailed lemur (Lemur catta)

LCF is supporting projects in Anjanaharibe-Sud Special Reserve (ASSR), a large mountainous rainforest in northeastern Madagascar, which has long been recognized as a lemur priority site. At least 11 lemur species are found here including:

  • Indri (Indri indri)
  • Silky sifaka (Propithecus candidus)
  • Aye-aye (Daubentonia madagascariensis)
  • Mittermeier’s mouse lemur (Microcebus mittermeieri)
  • Northern bamboo lemur (Hapalemur occidentalis)

How We Support Local Communities

Educational Outreach

We have the pleasure of continuing Dr. Alison Jolly’s legacy with the Ako Project, in collaboration with Dr. Hanta Rasamimanana, Dr. Jolly’s former colleague, professor at ENS, and Madagascar’s “Lemur Lady”.

The first book in the Ako Project series, Ako the Aye-Aye.

The first book in the Ako Project series, Ako the Aye-Aye.

The Ako Project, sponsored by EnviroKidz, is an educational children’s book series, translated in both English and Malagasy, which is intended to teach Malagasy children about different species of lemur in a fun, tangible way. The books come with matching curriculum to help teachers convey the conservation themes and concepts envisioned for the stories.

Training support

LCF also collaborates with École Normale Supérieure (ENS), the teachers’ training arm of the University of Antananarivo. This partnership supports the students of ENS in their field research and field work theses at the Berenty Reserve, a private wildlife reserve in southern Madagascar. Research done at Berenty includes lemur census surveys and plant phenology.

Biodiversity Conservation Madagascar

What We Do

Biodiversity Conservation MadagascarBiodiversity Conservation Madagascar (BCM) was established in 2002 as the conservation arm of Bioculture (Mauritius) Ltd. Our main goals are to conserve threatened forests in east and west Madagascar that are of high biodiversity value, especially those rich in lemur species. We currently work in the 2,400 hectare lowland rainforest in Sahafina (East Madagascar) and the Beanka dry deciduous forest in the Maintirano region (West Madagascar).

How We Protect Lemurs And Other Wildlife

BCM manages the conservation of two forests on behalf of the Malagasy government through “Conservation Leases.” Since 2003, we have been responsible for the protection of 2,400 hectares of humid low altitudinal forest in eastern Madagascar. In 2007, BCM started managing a second site—the Beanka New Protected Area in Western Madagascar. This 17,000 hectare forest is of significant ecological value and harbors a rich diversity of plants and animals.
We employ forest guards to reduce deforestation and poaching of lemurs.

What Lemur Species We Protect

We work in both east (Sahafina, near Brickaville) and west (Maintirano region) Madagascar protecting lemur species across both regions.

In the Benka conservation site, the program works to protect the following species:

  • Bemaraha woolly lemur (Avahi cleesei)
  • Fat-tailed dwarf lemur (Cheirogaleus medius)
  • Dwarf lemur (Cheirogaleus sp.)
  • Aye-aye (Daubentonia madagascariensis)
  • Red-fronted lemur (Eulemur rufus)
  • Eastern lesser bamboo lemur (Hapalemur griseus)
  • Randrianasolo’s sportive lemur (Lepilemur cf. randrianasoli)
  • Pygmy mouse lemur (Microcebus myoxinus)
  • Giant mouse lemur (Mirza sp.)
  • Pale fork-marked lemur (Phaner pallescens)
  • Decken’s sifaka (Propithecus deckenii)

In their Sahafina project site, they protect:

  • Eastern woolly lemur (Avahi laniger)
  • Greater dwarf lemur (Cheirogaleus major)
  • Aye-aye (Daubentonia madagascariensis)
  • Red-bellied lemur (Eulemur rubriventer)
  • Eastern lesser bamboo lemur (Hapalemur griseus)
  • Indri (Indri indri)
  • Brown mouse lemur (Microcebus rufus)

How We Support Local Communities

One of our primary approaches to forest protection includes the use of conservation payments to local communities. This program ensures that communities receive direct material benefits in exchange for supporting ongoing conservation projects.

Biodiversity Conservation Madagascar also implements the following programs in partnership with local communities:

Eucalyptus and fruit tree plantations

To alleviate pressures on the forest, at BCM we manage the growing and planting of Eucalyptus trees, which provide a good source of fuel and construction materials for local communities. Eucalyptus trees, due to their ability to grow quickly and without a lot of water, are an ideal replacement for the precious and slow-growing hardwood trees that have been traditionally cut down by Malagasy communities. BCM has also helped plant fruit trees in local villages to provide a secondary source of food and income to the local people.
Biodiversity Conservation Madagascar WaterWellBeanka

Water wells

BCM has provided the materials for local communities to build four water wells. This is of considerable importance as it helps assure a continuous water supply for the local community.

Agricultural training

BCM has trained local communities on how to effectively grow vegetables and to improve their rice growing techniques.

Lee Durrell releasing ploughshare tortoises in 2011.

American Friends of Durrell promotes and supports the work of Durrell Wildlife Conservation Trust (DWCT), a British wildlife charity established in 1963 by author and conservationist, Gerald Durrell. DWCT’s mission is to save species from extinction.

In Madagascar, the DWCT has been undertaking conservation actions for species and habitats since 1983. It has pioneered efforts for breeding and release-to-the wild of critically endangered species, for protecting vulnerable habitats and for enabling and empowering local communities to manage their natural environments sustainably. DWCT’s Madagascar Program employs approximately 30 people, mostly Malagasy nationals, and operates at eight sites. Lemurs are flagship species for two of the sites where the DWCT works: the Alaotran gentle lemur at Lac Alaotra and the black and white ruffed lemur at Manombo.

The American Friends of Durrell currently contribute to two of DWCT’s projects: (1) the Alison Jolly Madagascar Scholarship; and (2) the Madagascar Program Management and Coordination fund, which essentially covers the core costs of DWCT’s work in Madagascar. In the future, the American Friends of Durrell will likely increase their funding of the organization’s programs, especially as it relates to lemur conservation.

How We Protect Lemurs And Other Wildlife

Durrell Conservation Alaotran gentle lemurs

Thanks to the help of the American Friends of Durrell, the DWCT in Madagascar has been able to achieve several landmark moments in lemur conservation. Notable successes include the establishment of a Ramsar Site for Lac Alaotra (East Madagascar) and a National Park at Baly Bay (West Madagascar).

What Lemur Species We Protect

Lemurs are flagship species for two of the sites where the DWCT works: the Alaotran gentle lemur (Hapalemur alaotrensis) at Lac Alaotra (East Madagascar) and the Black-and-white ruffed lemur (Varecia variegata) at Manombo (Southeast Madagascar).

How We Support Local Communities

DWCT pioneered its approach to partnering with local communities in the early 1990s on the project to save the ploughshare tortoise of Madagascar. It was inspired and led by the late Lala Jean Rakotoniaina, who became DWCT’s Community Conservation Coordinator and a Disney Conservation Hero. Now all of DWCT’s work in Madagascar – and elsewhere in the world – is modeled on this approach, with local communities participating in management actions and ultimately taking on decisions concerning their natural resources. The empowerment of local communities helps increase the sustainability of programming, and therefore the viability of species and target habitats.

Centre ValBio & the Institute for the Conservation of Tropical Environments

Centre ValBio & the Institute for the Conservation of Tropical Environments

What We Do

Centre Valbio Ewing People Outside (1)

The Centre ValBio – a cutting-edge research station in Madagascar.

The Institute for the Conservation of Tropical Environments (ICTE) was established by Dr. Patricia Wright in 1991 to encourage and promote scientific research, training and conservation in the tropics. We (together with Stony Brook University) maintain a state-of-the-art research station, Centre ValBio, adjacent to Ranomafana National Park in eastern Madagascar. This research station hosts hundreds of researchers, students, and eco-tourists each year; it is truly the only facility of its kind in the country.

Centre ValBio (CVB) was founded in 2003 and helps both indigenous people and the international community better understand the value of conservation in Madagascar and around the world.

Centre Valbio has three main objectives:

  1. To promote world-class research in one of the world’s most biologically diverse and unique ecosystems
  2. To encourage environmental conservation by developing ecologically sustainable economic development programs with local villages
  3. To provide the local villagers with the knowledge and tools to improve their quality of life through projects focused on sanitation, diet, and education, and ultimately reduce poverty in the area

How We Protect Lemurs And Other Wildlife

Centre valbio wildlife

Wildlife in the Ranomafana National Park.

The Ranomafana National Park – which protects 41,500 hectares of rainforest – was created with the help of Dr. Patricia Wright, the founder of ICTE and Centre Valbio. Since the creation of this park, the organization has continued to help bring attention to the plight of lemurs and biodiversity in Madagascar at the regional, national, and international level.

Long-term research programs are a big priority for ICTE. We train scientists at all levels through field-based courses, collaborations, and academic exchanges. More than 400 scientific publications have directly resulted from work conducted in partnership with the Centre ValBio. In addition, we also conduct biodiversity research and ecological assessments of tropical ecosystems, and coordinate and catalog the work of over 800 natural and social scientists!

Successes at Centre ValBio include the translocation of three Greater bamboo lemur from a forest fragment to the national park, as well as the discovery of a thriving group in a nearby region!

What Lemur Species We Protect

The work of ICTE/Centre Valbio places particular emphasis on the region surrounding the Ranomafana National Park, in eastern Madagascar. This park is host to several lemur species, including:

  • Aye aye (Daubentonia madagascariensis)
  • Brown mouse lemur (Microcebus rufus)
  • Eastern wooly lemur (Avahi laniger)
  • Golden bamboo lemur (Hapalemur aureus)
  • Greater bamboo lemur (Prolemur simus)
  • Milne-Edwards’ sifaka (Propithecus edwardsi)

How We Support Local Communities

Centre Valbio conservation programs

Centre ValBio’s conservation programs have also included reforestation and education initiatives.

One of the central missions of ICTE/Centre Valbio has been collaboration and partnerships with the local Malagasy community. We employ over 80 local Malagasy as guides and staff for the research station, and opened up opportunities for work in the park and surrounding areas. In addition to providing sustainable employment, Centre Valbio organizes multiple outreach programs in the fields of education, the arts, sustainable agriculture, and reforestation.

Conservation outreach

Centre ValBio leads outreach and public awareness programs that highlight the unique biodiversity of Madagascar; most of this is achieved through 15 conservation clubs spread across 22 villages that contain almost 500 members. Audiovisual and hands-on demonstrations are also used to deliver education on biodiversity and reforestation in 19 local schools. Centre ValBio and ICTE also support a range of education initiatives in the Ranomafana region.

Centre ValBio donates food to local community

Centre ValBio donates food to local community thanks to the help of an emergency fund.

Reforestation program

Centre ValBio undertakes educational outreach aimed at teaching the value of trees, not just for animals, but for clean water and erosion control as well. Reforestation initiatives have also targeted schools through their “from schools to the communities programs”, which has worked with 22 villages and 15 clubs on reforestation initiatives.

Health and hygiene

At Centre Valbio we work to improve the local communities’ nutritional conditions through education, implementation of infrastructure, and follow-up on improved sanitary practices. For example, we provide seeds and training for vegetable gardens to improve nutritional conditions in impoverished rural communities.

Duke Lemur Center

What We Do

Founded in 1966, the Duke Lemur Center (DLC) at Duke University (Durham, North Carolina, USA) is an internationally acclaimed non-invasive research center housing over 200 lemurs across 14 species: the most diverse population of lemurs on Earth, outside their native Madagascar.

Because all of our research is non-invasive, the DLC is open to the public and educates more than 35,000 visitors annually. DLC’s highly successful conservation breeding program seeks to preserve vanishing species such as the aye-aye, Coquerel’s sifaka, and blue-eyed black lemur. Our Madagascar Conservation Programs study and protect lemurs (the most endangered mammals on Earth) in their native habitat. The Division of Fossil Primates examines primate extinction and evolution over time and houses over 35,000 fossils, including extinct giant lemurs and one of the world’s largest and most important collections of early anthropoid primates.

How We Protect Lemurs And Other Wildlife

DLC’s SAVA Conservation project is dedicated to preserving the natural biodiversity of Madagascar, especially its charismatic lemurs, by empowering local communities to be conservation leaders.

Collaboration with National Parks

Clear delineation of the park boundaries is essential to maintaining and monitoring the forest.

We’ve helped increase protection and monitoring of parks in Madagascar. For example at Marojejy, we have continued to sponsor clearing the park limits, painting trees, and hanging new signs for boundary demarcation, and a road-block barrier to prevent trucks from transporting precious wood out of the forest. We also help support monitoring work undertaken by village guards and park staff.

Manantenina near the Marojejy National Park lacks reliable sources of clean water because local sources are often contaminated with disease-causing microbes. We created a partnership agreement with the community to install a deep-water well that will maintain safe water even during the dry season.

Research

CURSA researchers and local forest managers in the COMATSA protected area of the SAVA region.

In collaboration with the local university (CURSA), we study lemur viability in protected areas in SAVA.

We have partnered with Malagasy PhD and Masters students on their thesis projects on the ecology and conservation of lemurs in the COMATSA, a corridor between Marojejy, Anjanaharibe-Sud, and Tsaratanana.

In addition to research in the forest on lemurs, the team conducts socio-ecological research with the communities. Through focus groups, key-informant interviews, and lemur awareness campaigns, the team is learning about how people use forest resources, especially the level of hunting.In collaboration with CURSA, we are studying the links between socioeconomics, agriculture, nutrition, and health.

Conservation Breeding Program

We maintain the world’s largest “genetic safety net” for endangered lemurs. At the Duke Lemur Center in Durham, North Carolina, USA we’re proud to have celebrated more than 3,405 births through our conservation breeding program since our founding in 1966.

What Lemur Species We Protect

At Duke Lemur Center we house the following lemur species for breeding and non-invasive research:

  • Aye-aye (Daubentonia madagascariensis)
  • Black and White Ruffed Lemur (Varecia variegata variegata)
  • Blue-eyed Black lemur (Eulemur flavifrons)
  • Collared Lemur (Eulemur collaris)
  • Coquerel’s Sifaka (Propithecus coquereli)
  • Crowned Lemur (Eulemur coronatus)
  • Eastern Lesser Bamboo Lemur (Hapalemur griseus)
  • Fat-tailed Dwarf Lemur (Cheirogaleus medius)
  • Grey Mouse Lemur (Microcebus murinus)
  • Mongoose Lemur (Eulemur mongoz)
  • Red-bellied Lemur (Eulemur rubriventer)
  • Red-fronted Lemur (Eulemur rufifrons)
  • Red Ruffed Lemur (Varecia rubra)
  • Ring-tailed Lemur (Lemur catta)

We also support research focusing on the Silky Sifaka (Propithecus candidus) a highly endangered lemur found in the north east of Madagascar.

How We Support Local Communities

Our goals are preserving natural environments as well as increasing sustainability and resilience. We achieve these goals through activities centered on education, reforestation, sustainable agriculture, fuel-efficient stoves, women’s health, and much more.

Environmental education (EE)

Fostering a generation of environmental stewards begins in the school classroom with Madagascar’s youth, and incorporating the environment into daily classroom instruction can lead to a generation of Malagasy people interested in and equipped to protect their natural heritage.

Children proudly display their Lemur Appreciation certificates after a school visit in Manantenina

We introduced an environmental education training manual originally developed by the Madagascar Flora and Fauna Group and the Ministry of Education. In partnership with skilled Malagasy educators, the DLC has introduced and trained school officials on the implementation of the educational curriculum into daily lesson plans. This approach ensures that the environmental education program is widely adopted from all levels of the education system. We want to ensure that the information is presented in a standardized and culturally sensitive manner, and therefore more readily adopted by the teachers on a daily basis. In collaboration with the school districts of Sambava and Andapa, we’ve conducted workshops with over 2,000 teachers to train them to incorporate environmental education into daily lessons.

Landscape Restoration

DLC sponsored tree nursery with the local school at Belaoka-Marovato, Andapa district.

We maintain tree nurseries with communities to supply high quality seedlings of diverse trees including over a dozen native species, cash crops like coffee, cloves, and cacao, and over a dozen fruit species. As of the writing of this article, we partner with five communities to maintain tree nurseries and support their reforestation efforts. Each nursery produces approximately 25,000 seedlings per year, which are distributed to the community members to plant on their lands and during group planting events. Our staff provide consultation on proper planting techniques and follow up evaluations to determine seedling survival.

We are partnered with local collaborators to maintain and monitor 4 reforestation plantations throughout the SAVA region, with over 59,000 trees planted on 20 hectares in 2021.

CURSA Director, Dr. MANJARIBE Christophe (left) demonstrates proper tree planting techniques with staff and students at their demonstration agroforestry field station.

Information campaign and distribution of fuel-efficient ‘rocket’ stoves

More than 80% of people in Madagascar use firewood or charcoal to cook. We partner with the Swiss organization ADES, which produces fuel-efficient stoves in Madagascar that burn 1/3 the biomass of firewood or charcoal compared to traditional stoves. Between 2020 and 2021 alone, over 500 households received training and subsidized stoves. Stoves are sold during demonstrations, and through local entrepreneurs serving as distributors. We are evaluating participants, and found 100% of users are satisfied and save 25-50kg of charcoal on average per month.

Women’s reproductive health

We maintain collaboration with British NGO Marie Stopes International, to support nurses visiting remote villages and providing consultation and services on women’s health and reproduction.

Oxford Brookes University: Nocturnal Primate Research Group

What We Do

We are among the leading groups in charge of developing research and conservation in the recently established protected area of Tsitongambarika (south-east corner of Madagascar). No systematic research had been conducted before our arrival. It is considered one of the Lemur Action Plan priorities and one of the last large expanses of lowland rainforest left in Madagascar.

Studying the Activity of Cathemeral Lemurs

Since 1995, we have been studying the proximate and ultimate determinants of day-night activity (aka cathemeral activity) in true lemurs. This activity pattern is extremely rare among primates but common in lemurs, thus offering the unique opportunity to study the key transition between nocturnal and diurnal life during primate evolution.

Studying How Lemurs Respond to Changes in Food Availability and Habitat

A second main stream of our research is focusing on lemur response to change in food availability and habitat disturbance. Since most forested areas in Madagascar have been modified by humans, understanding how lemurs respond to habitat disturbance and/or how they cope with new habitats is urgent. This response is investigated at various levels including thermoregulation, activity and ranging pattern, diet composition and nutritional ecology.

Studying Lemurs in the South-eastern Literal Forest, Andasibe, and Sahamalaza

Since 1999, we have also studied the archipelago of fragments of the south-eastern littoral forest. And, members of our research groups have also studied the behavioural ecology of lemur species in Andasibe and Sahamalaza.

What Lemur Species We Study

The lemur species and field sites where we conducted our work on cathemeral activity are:

  • Collared brown lemur (Eulemur collaris) and Southern lesser bamboo lemur (Hapalemur meridionalis) in the littoral forests of Mandena and Sainte Luce (Fort Dauphin)
  • Ring-tailed lemur (Lemur catta) and Eulemur hybrids in the gallery forest of Berenty (Fort Dauphin)
  • Red-fronted lemur (Eulemur rufifrons) in the dry forest of Kirindy (Morondava)

Lemurs in the south-eastern littoral forest include:

  • Collared brown lemur (Eulemur collaris)
  • Southern lesser bamboo lemur (Hapalemur meridionalis)
  • Southern woolly lemur (Avahi meridionalis)
  • Dwarf lemurs (Cheirogaleus sp.)
  • Mouse lemurs (Microcebus sp.)

Behavioral Ecology, Health and Conservation of Wild Primates

Dr. Mitchell Irwin’s research examines the ecology and behavior of lemurs in a range of habitat types (from highly disturbed fragments to relatively intact continuous forest) in Tsinjoarivo, eastern Madagascar.

One major focus of this research is improving our understanding of lemurs’ unique adaptations (compared to other primates), which might be linked to ecological conditions in Madagascar. The second major focus is examining lemurs’ range of habitat tolerances and their ecological and behavioral responses to habitat disturbance and fragmentation.
