Two New Species of Mouse Lemurs (Cheirogaleidae: Microcebus) from Eastern Madagascar

International Journal of Primatology, 2013
The number of newly discovered Malagasy vertebrate taxa has multiplied in recent years, emphasizing the importance of complete taxon sampling for phylogenetics, biogeography, functional ecology, and conservation biology, especially in such a biodiversity hotspot.

Ancient Introgression in Mouse Lemurs (Microcebus: Cheirogaleidae) Explains 20 Years of Phylogenetic Uncertainty

Bulletin of the Society of Systematic Biologists
Mouse lemurs (genus Microcebus) are a clade of approximately 26 named species of small, nocturnal primates endemic to Madagascar. The genus radiated one to ten million years ago and is morphologically cryptic, with most species having been named within ...

The red island and the seven dwarfs: body size reduction in Cheirogaleidae

Journal of Biogeography, 2014
AbstractAimSmall body size in Madagascar's dwarf and mouse lemurs (Cheirogaleidae) is generally viewed as primitive. We investigated the evolution of body size in this family and in its sister‐taxon, the Lepilemuridae, from phylogenetic, ontogenetic and adaptive perspectives.LocationMadagascar.MethodsWe used a phylogenetic method to reconstruct the ...

Effect of socio-ecological factors and parasite infection on body condition of Brown Mouse Lemur Microcebus rufus (Mammalia: Primates: Cheirogaleidae)

Journal of Threatened Taxa, 2019
Various studies in ecology have shown the relationship between body condition and parasitic loads in nonhuman primates, however, little information is available regarding prosimians such as lemurs.

Revision of Madagascar's Dwarf Lemurs (Cheirogaleidae: Cheirogaleus): Designation of Species, Candidate Species Status and Geographic Boundaries Based on Molecular and Morphological Data [PDF]

Primate Conservation, 2014
Abstract: The genus Cheirogaleus, the dwarf lemurs, is a radiation of strepsirrhine primates endemic to the island of Madagascar. The dwarf lemurs are taxonomically grouped in the family Cheirogaleidae (Infraorder: Lemuriformes) along with the genera Microcebus, Mirza, Allocebus, and Phaner.

Predation in the dark: antipredator strategies of Cheirogaleidae and other nocturnal primates

, 2016
Predation can incur extreme fitness costs and can therefore drive the evolution and maintenance of elaborate and costly antipredator behavior in prey species (Caro, 2005; Fichtel, 2012). Although about one-third of all primates are nocturnal, small-bodied, and presumably facing a high predation risk (van Noordwijk et al., 1993; Isbell, 1994; Janson ...

Contribution of small nocturnal lemurs to seed dispersal in Madagascar: A review

Biotropica, Volume 57, Issue 1, January 2025.
Animal seed dispersers are crucial in tropical forests because they provide beneficial impacts to plants, from organisms to communities. Besides frugivorous species, omnivorous, small‐bodied, and nocturnal animals might also disperse seeds in their ...

Arboreal mouse lemurs discovered sleeping in a burrow on the ground. [PDF]

Ecol Evol, 2022
We report here an unprecedented event of a mouse lemur sleeping in a burrow on the rainforest ground. We believe that this discovery could illustrate an ecophysiological response strategy to habitat changes. Abstract Finding sleeping sites is important for the fitness of many mammal species. Like most nonhuman primates, Madagascar's mouse lemurs (genus:

Microgeographic heterogeneity in spatial distribution and mtDNA variability of gray mouse lemurs (Microcebus murinus, Primates: Cheirogaleidae)

Behavioral Ecology and Sociobiology, 2004
The objective of our study was to investigate the spatial distribution and genetic structure of a solitary primate at the microgeographical scale of adjacent local populations. We obtained spatial data and tissue samples for mtDNA analysis from 205 gray mouse lemurs (Microcebus murinus) captured along transects and within 3 grid systems within a 12.3 ...
