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.

Morphological and Molecular Identification of Tritrichomonas mobilensis in Captive Ring-Tailed Lemurs (Lemur catta) [PDF]
Veterinary SciencesIn September 2024, an acute hemorrhagic diarrhea occurred in a colony of captive ring-tailed lemurs (Lemur catta) housed adjacent to an enclosure of squirrel monkeys in Henan Province, China. Three of the ring-tailed lemurs (1-year-old females) died, 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 ...

Genetic analysis of hybridization and introgression between wild mongoose and brown lemurs [PDF]
BMC Evolutionary Biology, 2009 Background Hybrid zones generally represent areas of secondary contact after speciation. The nature of the interaction between genes of individuals in a hybrid zone is of interest in the study of evolutionary processes.

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 ...

Evolutionary history, longevity and terrestriality predict Toxoplasma gondii seroprevalence in free-ranging non-human primates [PDF]
International Journal for Parasitology: Parasites and WildlifeEvidence from captive populations indicates that lemurs are particularly vulnerable to toxoplasmosis, a parasitic disease caused by Toxoplasma gondii. In wild populations, however, seroprevalence in lemurs remains low.

Power Through or Keep Looking? Comparing Species‐Area Relationships of Habitat Fragments and Their Drivers in Different Ecoregions [PDF]
Ecology and EvolutionOur study aimed to (1) determine how the shape varies and mechanisms influence species‐area relationships within the same taxon but between different ecoregions and (2) determine how slope (z) and intercept (c) values of the linearized power model were ...

What can hippopotamus isotopes tell us about past distributions of C4 grassy biomes on Madagascar?
Plants, People, Planet, 2023 Societal Impact Statement Today, expansive C4 grassy biomes exist across central, western, and northern Madagascar. Some researchers have argued that the island's now‐extinct pygmy hippopotamuses belonged to a megaherbivore grazing guild that maintained ...
