Morphological and Molecular Identification of Tritrichomonas mobilensis in Captive Ring-Tailed Lemurs (Lemur catta) [PDF]

Veterinary Sciences
In 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

Evolutionary history, longevity and terrestriality predict Toxoplasma gondii seroprevalence in free-ranging non-human primates [PDF]

International Journal for Parasitology: Parasites and Wildlife
Evidence 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 Evolution
Our 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 ...

On the modulation and maintenance of hibernation in captive dwarf lemurs

Scientific Reports, 2021
In nature, photoperiod signals environmental seasonality and is a strong selective “zeitgeber” that synchronizes biological rhythms. For animals facing seasonal environmental challenges and energetic bottlenecks, daily torpor and hibernation are two ...

Seasonal variation in glucose and insulin is modulated by food and temperature conditions in a hibernating primate

Frontiers in Physiology, 2023
Feast-fast cycles allow animals to live in seasonal environments by promoting fat storage when food is plentiful and lipolysis when food is scarce.

Testing the adaptive radiation hypothesis for the lemurs of Madagascar [PDF]

Royal Society Open Science, 2017
Lemurs, the diverse, endemic primates of Madagascar, are thought to represent a classic example of adaptive radiation. Based on the most complete phylogeny of living and extinct lemurs yet assembled, I tested predictions of adaptive radiation theory by ...

Comparison of the Glucocorticoid Concentrations between Three Species of Lemuridae Kept in a Temporary Housing Facility

Animals, 2020
We compared the glucocorticoid concentrations in response to various types of potential stressors present during standard operation of a temporary housing facility between three species, namely, ring-tailed lemurs, collared brown lemurs and white-headed ...

Molecular Adaptation to Folivory and the Conservation Implications for Madagascar’s Lemurs

Frontiers in Ecology and Evolution, 2021
The lemurs of Madagascar include numerous species characterized by folivory across several families. Many extant lemuriform folivores exist in sympatry in Madagascar’s remaining forests.

Molecular and Serological Studies on Potential SARS-CoV-2 Infection among 43 Lemurs under Human Care—Evidence for Past Infection in at Least One Individual

Animals, 2023
In the setting of the recent COVID-19 pandemic, transmission of SARS-CoV-2 to animals has been reported in both domestic and wild animals and is a matter of concern.
