Northern giant mouse lemur range [1]

The northern giant mouse lemur (Mirza zaza), or northern dwarf lemur, is a species of lemur discovered in 2005. [3] 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. [4]

Etymology

The word zaza means child in Malagasy. The name was chosen because the northern giant mouse lemur is the smaller of the two giant mouse lemur species, and because of a wish to emphasize the responsibility of the current generation of Malagasy children for the conservation of Malagasy animals for future generations. [3]

Description

The northern giant mouse lemur is relatively small, with juveniles weighing 150 - 199 g, subadults 200 - 249 g, and fully grown adults 250 - 300 g. [5] This species has large testes, among the largest relative testes to body size in the Primate order. [6]

Distribution

The M. zaza are found in a strictly limited region in the north-western part of Madagascar, the Ampasindava peninsula. [7] The habitat is split by two rivers, the Mahavavy River to the north and the Maevarano River to the south. In some areas it is further separated by the Sambirano River. [5] This area in Madagascar has a dry and cool season from May to October, and a wet and hot season from November to April. The species can be found in a transition zone which goes to the Sambirano evergreen rainforest that extends to the north. [8] Home ranges cover 0.52 - 2.34 ha. [5] There is no substantial overlap in home ranges among individuals. [9] An estimated 385 - 1,086 individuals per km2 are present throughout the region. [1]

Behavior

The species has a polygynandrous mating system, likely based on the large size of the testes, which engenders strong sperm competition. Breeding is aseasonal. [6]

The northern mouse lemur is nocturnal, feeding predominantly during the second half of the night. On average, individuals stay approximately 7 meters up in the canopy. During the day they sleep in group-exclusive tree holes. Nesting groups are 2 - 8 individuals in size, made up of both sexes and any age class, and include unrelated males. [5]

Conservation

The species is classified as vulnerable by the IUCN primarily due to loss of habitat. [1] The deciduous forests that they live in are being logged, fragmented, and degraded. [5] The species is listed in CITES Appendix I. [2]

<span class="mw-page-title-main">Gray mouse lemur</span> Small primate from Madagascar

The gray mouse lemur, grey mouse lemur or lesser mouse lemur, is a small lemur, a type of strepsirrhine primate, found only on the island of Madagascar. Weighing 58 to 67 grams, it is the largest of the mouse lemurs, a group that includes the smallest primates in the world. The species is named for its mouse-like size and coloration and is known locally as tsidy, koitsiky, titilivaha, pondiky, and vakiandry. The gray mouse lemur and all other mouse lemurs are considered cryptic species, as they are nearly indistinguishable from each other by appearance. For this reason, the gray mouse lemur was considered the only mouse lemur species for decades until more recent studies began to distinguish between the species.

<span class="mw-page-title-main">Giant mouse lemur</span> Genus of small primates from Madagascar

The giant mouse lemurs are members of the strepsirrhine primate genus Mirza. Two species have been formally described; the northern giant mouse lemur and Coquerel's giant mouse lemur. Like all other lemurs, they are native to Madagascar, where they are found in the western dry deciduous forests and further to the north in the Sambirano Valley and Sahamalaza Peninsula. First described in 1867 as a single species, they were grouped with mouse lemurs and dwarf lemurs. In 1870, British zoologist John Edward Gray assigned them to their own genus, Mirza. The classification was not widely accepted until the 1990s, which followed the revival of the genus by American paleoanthropologist Ian Tattersall in 1982. In 2005, the northern population was declared a new species, and in 2010, the World Wide Fund for Nature announced that a southwestern population might also be a new species.

Claire's mouse lemur, or the Nosy Be mouse lemur, is a newly described species of lemur from the genus of the mouse lemurs (Microcebus). It lives on the island Nosy Bé in the Antsiranana province of Madagascar, and on the mainland near the village of Manehoka, including Lokobe Reserve. The scientific type name, mamiratra, comes from Malagasy and means "clear and bright"; this refers the Theodore F. and Claire M. Hubbard Family Foundation, which has contributed to genetic research on Madagascar. This species is closely related to another new species, "M. species nova # 5"; which is related to the Sambirano mouse lemur, Microcebus sambiranensis, and the northern rufous mouse lemur, Microcebus tavaratra.

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.

<span class="mw-page-title-main">Taxonomy of lemurs</span> Science of describing species and defining the evolutionary relationships between taxa of lemurs

Lemurs were first classified in 1758 by Carl Linnaeus, and the taxonomy remains controversial today, with approximately 70 to 100 species and subspecies recognized, depending on how the term "species" is defined. Having undergone their own independent evolution on Madagascar, lemurs have diversified to fill many ecological niches normally filled by other types of mammals. They include the smallest primates in the world, and once included some of the largest. Since the arrival of humans approximately 2,000 years ago, lemurs have become restricted to 10% of the island, or approximately 60,000 square kilometers (23,000 sq mi), and many face extinction. Concerns over lemur conservation have affected lemur taxonomy, since distinct species receive increased conservation attention compared to subspecies.

The Nosy Boraha mouse lemur is a species of mouse lemur described in 2016 from Madagascar. It was discovered by a team of researchers at the German Primate Center. It was initially discovered among closely related species such as Madame Berthe's mouse lemur, Bemanasy mouse lemur, and Ganzhorn's mouse lemur. Morphological similarity made it impossible to identify them as distinct species. A genetic study was done in collaboration with scientists at the University of Kentucky, the Duke Lemur Center and the University of Antananarivo in Madagascar. The mtDNA sequencing revealed that the species was unique.
