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.

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

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 ...

Coevolution of Cyanogenic Bamboos and Bamboo Lemurs on Madagascar. [PDF]

PLoS ONE, 2016
Feeding strategies of specialist herbivores often originate from the coevolutionary arms race of plant defenses and counter-adaptations of herbivores. The interaction between bamboo lemurs and cyanogenic bamboos on Madagascar represents a unique system ...

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.

Combination of intramuscular alfaxalone, butorphanol, and midazolam as a novel immobilization protocol in 3 ring-tailed lemurs (Lemur catta)

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 ...
