I propose to do an in-depth quantitative ecological assessment of several lemur species, including Coquerel's sifaka (Propithecus coquereli), in various forest fragments in the Mahamavo region (NW Madagascar), where their habitat is threatened by deforestation.

Did you know? A new species of lemur has been discovered 😀 The 𝘔𝘪𝘤𝘳𝘰𝘤𝘦𝘣𝘶𝘴 jonahi is the new member of the Mouse lemur family and is one of the smallest lemurs in the world and found in the Mananara-Nord National Park community protected forests of Antsiradrano and Madera. We are currently at 113 endemic species in Madagascar. Hope after the update of the IUCN red list for endangered species. 🤝Thanks to the collaboration with international scientists, and to the several years of research. They unanimously decided to name it after 𝗣𝗿 𝗝𝗼𝗻𝗮𝗵 𝗥𝗮𝘁𝘀𝗶𝗺𝗯𝗮𝘇𝗮𝗳𝘆 (President of GERP, IPS, and one of the founders of Madagascar Lemurs Portal) 👉 He is best known to all as the voice of our dearest lemurs by his determination, his passion, his love in this fight for the protection of these emblematic species for the future generation. 👉 To know more about it.

Gland, Switzerland, 9 July 2020 (IUCN) – Almost a third (31%) of all lemur species in Madagascar are now Critically Endangered – just one step away from extinction – with 98% of them threatened, according to today’s update of The IUCN Red List of Threatened SpeciesTM. This update completes a revision of all African primate assessments, concluding that over half of all primate species in the rest of Africa are under threat. This update also reveals that the North Atlantic Right Whale and the European Hamster are now both Critically Endangered. Today’s update shows that 33 lemur species are Critically Endangered, with 103 of the 107 surviving species threatened with extinction, mainly due to deforestation and hunting in Madagascar. Thirteen lemur species have been pushed to higher threat categories as a result of intensifying human pressures. Among those newly listed as Critically Endangered are Verreaux’s Sifaka (Propithecus verreauxi) and Madame Berthe's Mouse Lemur (Microcebus berthae), the smallest primate in the world, both of which were previously listed as Endangered. These species are undergoing substantial declines as their forest habitats continue to be destroyed through slash and burn agriculture, as well as by logging for charcoal and fuel wood. Hunting further threatens Verreaux’s Sifaka, despite being illegal and regarded as taboo or ‘fady’ in many parts of its range. https://www.iucn.org/news/species/202007/almost-a-third-lemurs-and-north-atlantic-right-whale-now-critically-endangered-iucn-red-list

The World Health Organization has declared a global public health emergency in response to the Novel Coronavirus (COVID-19) Pandemic and there is now evidence of infection with the virus causing COVID-19 in Madagascar.1 As we prepare for this public health emergency, we must also recognize the potential threat of this pandemic to Madagascar's lemurs. Wild chimpanzees have experienced respiratory outbreaks following infection by human coronaviruses2 and it is highly probable that chimpanzees and other non-human primates, such as lemurs, are similarly susceptible to the virus causing COVID-19. Scientific research, ecotourism, and current conservation and management paradigms all have the capacity to subject habituated wild primates to risks of human pathogen exposure. Considering these risks it is recommended to suspend lemur tourism and reduce research activities subject to risk assessments to maximize conservation outcomes (for example, poaching or deforestation of lemur habitat could rise with fewer people in the vicinity). The IUCN Best Practice Guidelines for Health Monitoring and Disease Control in Great Ape Populations,3 were developed in response to a series of mortality events in habituated apes linked to human respiratory virus exposure4-6 and a greater recognition of the ease of wild ape exposure to human enteric pathogens.7,8 Fortunately, the majority of these guidelines are broadly applicable to habituated primates and are particularly relevant to the current COVID-19 pandemic. Implementing the following key guidelines across ecotourism and research sites in Madagascar for essential staff who continue to enter lemur habitat during the pandemic will substantially reduce the risk of lemur exposure to the virus causing COVID-19 or the multitude of other pathogens we may unintentionally introduce when we enter lemur habitats: 1) Sick? Stay home: No individual with clinical symptoms (i.e., nasal discharge, sore throat, cough, or fever) should enter lemur habitat). 2) Start clean for each visit: Individuals entering lemur habitat should wear clean clothing. Footwear should be disinfected and hands should be washed with soap and water before entering and again upon leaving habitat. 3) Stay away: Individuals should maintain a minimum distance of 7 meters from lemurs. 4) Wear a facemask: Individuals within 10 meters of lemurs should wear a surgical mask. 5) Sneeze right: If an individual must sneeze or cough while in proximity to lemurs, they should keep their mask on, turn away from animals, and cover mouth and nose with the crook of the elbow rather than the hand, or sneeze inside their clothing. The current COVID-19 pandemic should be considered a potential threat to the health of wild lemurs. There is no such thing as zero disease risk and taking measures to prevent or control disease will never eliminate all risks, therefore the recommendations herein are primarily aimed at minimizing, rather than trying to eliminate, the threat of disease transmission from humans to wild lemurs. Despite this caveat, implementing these best practices should substantially reduce the risks that human activities pose to lemur health and signal a clear commitment to primate conservation in Madagascar. 1https://www.who.int/emergencies/diseases/novel-coronavirus-2019 2Patrono, L.

Do you like adventure? Interested in learning about lemurs? Are you passionate about protecting the environment? Are you a student who has no background in conservation but wants to get involved? Then this program is for you! Come join both professionals from Lemurs Portal and passionate people alike on March 27-28, 2020 in the Maromizaha forest and learn how to get involved! Lemurs are an iconic image for Madagascar helping make our country the most biodiverse place in the world so it is important to protect them.Lemurs Portal is a project that has been working on a database that is available to the public and has made huge strides in lemur research, conservation and decision making. We created this event Bioblitz to give everyday citizens the opportunity to contribute to lemur conservation scientifically. It is a lot easier than you think it is! All that is required is for you to go to the forest with us and then learn about cataloging and describing lemurs.If you want to apply, please follow the link below and fill in the application form: https://docs.google.com/forms/d/e/1FAIpQLSd0Pt4e9Fk0Rj33ETzO-SMW0u_C9fXtcxqMQHjaoPvOfACbYw/viewform The deadline is March 19, 2020 at 12 pm Who doesn’t want to spend a couple days in a beautiful forest?

La vaste majorité des lémuriens, ces primates endémiques de Madagascar, sont en danger d'extinction. Voilà ce qu'on apprend sur la dernière liste rouge des espèces en danger, publiée par l'IUCN (Union internationale pour la conservation de la nature ). Sur les 111 espèces de lémuriens connues, 105 sont actuellement "en danger critique d'extinction", "en danger" ou "vulnérable", renforçant le statut des lémuriens comme primates les plus menacés sur la planète.

Bonjour, le terme de domestication du thème me semble porter à discussion. La domestication relève de mécanismes précis visant à créer une race domestique utile à l'homme ou une variété végétale avec dans tous les cas la sélection et le développement de caractères réunis dans le syndrome de domestication. Le terme d'apprivoisement me semble plus approprié en tout jusqu'à maintenant. Maurice ADIBA
