Touchscreen-based cognitive tasks reveal age-related impairment in a primate aging model, the grey mouse lemur (Microcebus murinus). [PDF]
PLoS ONE, 2014 Mouse lemurs are suggested to represent promising novel non-human primate models for aging research. However, standardized and cross-taxa cognitive testing methods are still lacking.

Photoperiodic regime influences onset of lens opacities in a non-human primate [PDF]
PeerJ, 2017 Background Opacities of the lens are typical age-related phenomena which have a high influence on photoreception and consequently circadian rhythm. In mouse lemurs, a small bodied non-human primate, a high incidence (more than 50% when >seven years) of ...

Toxoplasmosis in Captive Ring-Tailed Lemurs (Lemur catta)
Pathogens, 2022 Toxoplasma gondii is one of the most common protozoan parasites and is widely present in all warm-blooded animals. Although clinical disease is uncommon, some species, including ring-tailed lemurs (Lemur catta), have been found to develop acute and ...

Numerical Rule-Learning in Ring-Tailed Lemurs (Lemur catta) [PDF]
Frontiers in Psychology, 2011 We investigated numerical discrimination and numerical rule-learning in ring-tailed lemurs (Lemur catta). Two ring-tailed lemurs were trained to respond to two visual arrays, each of which contained between one and four elements, in numerically ...

Do lemurs know when they could be wrong? An investigation of information seeking in three species of lemur (Lemur catta, Eulemur rubriventer, and Varecia variegata) [PDF]
, 2020 Sixteen lemurs, including representatives from three species (Lemur catta, Eulemur rubriventer, Varecia variegata), were presented with a food seeking task where information about the rewards location, in one of two plastic tubes, was either known or not

Irish Veterinary Journal, 2020 Background There is very little data on the optimal anaesthetic management of ring-tailed lemurs, and the available information is mostly based on extrapolation from other species. In addition, a thorough pre-anaesthetic assessment of lemurs might not be

Assessing Allostatic Load in Ring-Tailed Lemurs (Lemur catta) [PDF]
Animals, 2021 Responses to stress are unavoidable, adaptive mechanisms in humans and non-human animals. However, in humans, chronic stress has been linked to poor health outcomes and early mortality. Allostatic load, the physiologic dysregulation that occurs when an organism is exposed to chronic stressors, has been used to assess stress in humans; less work has ...

A review on ocular findings in mouse lemurs: potential links to age and genetic background [PDF]
Primate Biology, 2017 Mouse lemurs, the world's smallest primates, inhabit forests in Madagascar. They are nocturnal, arboreal and dependent on vision for their everyday lives. In the last decades, the grey mouse lemur became increasingly important for biomedical research,

Lemurs before Lemur : depictions of captive lemurs prior to Linnaeus [PDF]
Notes and Records: the Royal Society Journal of the History of Science, 2021 In 1758, Carl von Linné (Linnaeus) published the tenth edition of Systema Naturae , in which he formally described the most unique group of primates: lemurs. The story of the early human-mediated dispersal of lemurs from Madagascar, prior to their formalized descriptions, is a complex one. It touches on the birth of

BMC Evolutionary Biology, 2018 Background Species recognition, i.e., the ability to distinguish conspecifics from heterospecifics, plays an essential role in reproduction. The role of facial cues for species recognition has been investigated in several non-human primate species except
