Mandena Conservation Zone is a conservation zone in southeast Madagascar.
The zone is located 10 kilometres north of Fort Dauphin, three kilometres from the southeast coast of the island country. The zone has 82 hectares of swamp, and 148 hectares of littoral forest. The 2,800 milimeters of rainfall mostly occurs in the November to April rainy season, the zone has a temperature range of 9.5 to 35 degrees Celsius. [1]
The zone is inhabited by Ganzhorn’s mouse lemur, eastern fat-tailed dwarf lemur, greater dwarf lemur, southern woolly lemur, Southern lesser bamboo lemur, [1] collared brown lemurs [2] and the Madagascan flying fox. [3]
The Cheirogaleidae are the family of strepsirrhine primates containing the various dwarf and mouse lemurs. Like all other lemurs, cheirogaleids live exclusively on the island of Madagascar.
The woolly lemurs, also known as avahis or woolly indris, are nine species of strepsirrhine primates in the genus Avahi. Like all other lemurs, they live only on the island of Madagascar.
The fat-tailed dwarf lemur, also known as the lesser dwarf lemur, western fat-tailed dwarf lemur, or spiny forest dwarf lemur, is endemic to Madagascar.
The Sambirano mouse lemur is a small, recently discovered primate and like the other mouse lemurs can only be found on the island of Madagascar. The dorsal side is both cinnamon and rufous-cinnamon and is grey ventrally. It has vibrissae that are dark in color.
The northern giant mouse lemur, or northern dwarf lemur, is a species of lemur discovered in 2005. They are part of the primate order, and classified in the family Cheirogaleidae. Previously, both populations of giant mouse lemurs were believed to belong to one species. The northern giant mouse lemurs are small nocturnal lemurs endemic to Madagascar. They weigh about 300 grams (11 oz), and have long, bushy tails and relatively small ears. Their large testicles are an indication of their promiscuous copulation system. These lemurs have been found to use communal sleeping nests including multiple males, which is an uncommon behaviour in lemurs.
Jolly's mouse lemur is a species of mouse lemur from Mananjary and Kianjavato in Madagascar. The species is named in honor of primatologist Alison Jolly.
Mittermeier's mouse lemur is a species of mouse lemur known only from Anjanaharibe-Sud Special Reserve in Madagascar.
Simmons' mouse lemur is a species of mouse lemur known only from Betampona Special Reserve, Analalava Special Community Reserve near Foulpointe, and Zahamena National Park in Madagascar.
The furry-eared dwarf lemur, or Crossley's dwarf lemur, only found on the island of Madagascar, as with all other lemurs. It has a pelage coloration that is red-brown dorsally and gray ventrally. The eye-rings of this species are blackish and the ears are black inside and out. Cheirogaleus crossleyi species are obligated to hibernate during periods of food scarcity on the island of Madagascar. Cheirogaleus crossleyi species specifically undergo drastic fluctuations in temperature during hibernation.
The reddish-gray mouse lemur also known as the gray-brown mouse lemur or rufous-gray mouse lemur, is a small, solitary-but-social, nocturnal and omnivorous primate from the Western Madagascar in the region around Beza Mahafaly Reserve, north to Lamboharana. Like the other lemur species, the reddish-grey mouse lemur is endemic to Madagascar. They generally live in the drier regions of the island. It is categorized as least concerned in the IUCN Red List.
Madame Berthe's mouse lemur or Berthe's mouse lemur is the smallest of the mouse lemurs and the smallest primate in the world; the average body length is 9.2 cm (3.6 in) and seasonal weight is around 30 g (1.1 oz). Microcebus berthae is one of many species of Malagasy lemurs that came about through extensive speciation, caused by unknown environmental mechanisms and conditions.
The mouse lemurs are nocturnal lemurs of the genus Microcebus. Like all lemurs, mouse lemurs are native to Madagascar.
The collared brown lemur, also known as the red-collared brown lemur or red-collared lemur, is a medium-sized strepsirrhine primate and one of twelve species of brown lemur in the family Lemuridae. It is only found in south-eastern Madagascar. Like most species of lemur, it is arboreal, moving quadrupedally and occasionally leaping from tree to tree. Like other brown lemurs, this species is cathemeral, lives in social groups, primarily eats fruit, exhibits sexual dichromatism, and does not demonstrate female dominance. The species is listed as Endangered by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss.
Danfoss's mouse lemur, or the Ambarijeby mouse lemur, is a species of mouse lemur endemic to Madagascar. It lives in western deciduous forest within a limited range between the Sofia River and the Maevarano River. This species has been found in substantial populations in the Ambarijevy, Anjajavy, and Beanamaolo forests in Madagascar. Their lifespan is about 5 years but can live up to 10 years. They are part of the infraorder called lemuriformes which represents 20% of the entire primates diversity and over 60% of the mammalian genera of Madagascar.
The southern woolly lemur, or southern avahi, has been recently recognized as a separate species of woolly lemur in 2006 by Zaramody et al. It is a nocturnal and pair-living species. Groups can range from 2 to 5 individuals. A study in Sainte Luce forest revealed home range varied from 2.2 to 3.5 ha and that males can have larger home range and cover longer daily distances than females, in agreement with the territory defence and mate guarding hypotheses.
The Betsileo woolly lemur or Betsileo avahi is a species of woolly lemur native to southeastern Madagascar, in the District of Fandriana. The pelage differs significantly from other southeastern woolly lemurs in that it is primarily light reddish brown on most of the body and grey under the jaw and on the extremities. The pelage is thicker on the head than other eastern woolly lemurs.
MacArthur's mouse lemur, or the Anjiahely mouse lemur, is a species of mouse lemur known only from Makira Natural Park in northeastern Madagascar.
The gray-headed lemur, or gray-headed brown lemur, is a medium-sized primate, a cathemeral species of lemur in the family Lemuridae. Until a taxonomic revision in 2008, it was known as the white-collared brown lemur or white-collared lemur. It lives in south-eastern Madagascar. In 2005, satellite imagery estimates showed approximately 700 km2 (270 sq mi) of total remaining habitat within its geographic range. It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008. It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range, and has been named one of "The World's 25 Most Endangered Primates."
