Recent genetic and acoustic analyses have revealed that the treefrogs once all lumped into the species Boophis marojezensis actually belong to eight different species.  These newly described species — three of which are found at different elevations in Marojejy — have unique and distinctive calls resembling the beeps of electronic instruments, and thus have been named after captains of the Star Trek television series.  May these little frogs all live long and prosper!

Read more about the study on Mark Scherz’s website, and in the journal Vertebrate Zoology.

New publication by Patrick Ross:  “Thin corridors limit wildlife: Variance of tropical carnivore distribution and habitat use in a critical rainforest corridor” in the journal Biotropica.

https://doi.org/10.1111/btp.13384

This manuscript sheds some light on the significant challenges faced by tropical carnivores in an increasingly narrow and critically important rainforest protected area of north-eastern Madagascar (COMATSA-Sud and Marojejy National Park).

By understanding the limitations these thinned corridors impose, we can better design and implement conservation strategies to preserve biodiversity and improve habitat connectivity.

An entertaining and informative progress report on a new elevational gradient survey of birds, lemurs, plants and insects being planned in Anjanaharibe-Sud Special Reserve. This will be the first such study since an initial survey was conducted in 1994; it will be interesting to learn how things have changed during the intervening 30 years.

A good article on work that the organization Wildlife Madagascar is doing in Marojejy’s sister park, Anjanaharibe-Sud — with a great photo of our good friend, Rodolphe Randriamisaina, who has been on countless expeditions to the area over the past few decades, a true hero.

A recent expedition to Makira Natural Park found a number of species that had not been seen in decades and had been presumed lost to science.

A photo of the Formidable Pygmy Grasshopper (Notocerus formidabilis), taken in Anjanaharibe-Sud Special Reserve and uploaded to the biodiversity observation program iNaturalist, has been featured in a recent article in the scientific journal Nature.

The Formidable Pygmy Grasshopper is a rare insect endemic to the SAVA region of Madagascar; it was originally described in 1974 but never observed again — until three of these grasshoppers were photographed in 2007, 2009 and 2015 by Éric Mathieu of marojejy.com. By uploading the photos to the iNaturalist platform, Mathieu was able to collaborate with two Croatian researchers, Marko Pavlović and Josip Skejo, who were able to not only identify the grasshopper but also discover its unique coloration, which hadn’t been previously described. Mathieu, Pavlović and Skejo ultimately co-authored a paper in the scientific journal ZooKeys on this new discovery.

As noted in the Nature article, illustrated by the example of the Formidable Pygmy Grasshopper, citizen science through platforms such as iNaturalist can be extremely powerful in adding to our understanding of the world’s biodiversity.

Another superb video from Duke Lemur Center – SAVA Conservation.

“A multidisciplinary team of researchers has been studying the complex relationships between people, plants and lemurs in COMATSA (a protected area near Marojejy and Anjanaharibe-Sud in the SAVA region). Researchers from local communities, Duke University, Duke Lemur Center, CURSA (the regional university of SAVA), and the University of Antananarivo are working together to study why these relationships are important and how environmental changes can alter essential ecological interactions. By integrating lemur studies, botanical plots, seed dispersal experiments and local ecological knowledge, the team hopes to advance the understanding of forest ecology and conservation in COMATSA.”

Seventy-four wildlife cameras (“camera traps”) were recently installed in Anjanaharibe-Sud Special Reserve (Marojejy’s sister park to the south) as part of a study to gain a better understanding of the wildlife populations in the area.  The study is focused primarily on the highly endangered Silky Sifaka population, but the cameras will be invaluable for recording movements of the many other species of lemurs, carnivores and birds in the area.  Here are a few articles on Patrick Ross’s fascinating study:

Thanks to all the people and entities involved.  We look forward to seeing the results!

We are delighted to learn that the well-regarded American NGO, Wildlife Madagascar, has designated Anjanaharibe-Sud Special Reserve (near Marojejy) as one of its first “conservation field sites.” Wildlife Madagascar is committed to working with local communities to conserve Madagascar’s extraordinary biodiversity; to that end, they will be conducting research, conservation and tourism activities in Anjanaharibe-Sud that will benefit both the wildlife and the local people. They are also planning on establishing a field office in Andapa.

Dr. Tim Eppley, Chief Conservation Officer of Wildlife Madagascar, recently visited Anjanaharibe-Sud and Marojejy and wrote an excellent summary of his trip, with descriptions of the area and the different species of lemurs he encountered. It’s well worth a read.

Fantastic picture of our good friend, Mosesy (Tabatera!), training new guides in Bobangira (a beautiful private reserve north of Sambava). Mosesy is a wonderful person and we are happy to see him doing so well after recent ill health.
