Summary: Research indicates that the allostatic load index (ALI) may be influenced by factors such as group size, indoor activity time, and frequency of group changes in ring-tailed lemurs, suggesting a relationship between these factors and stress levels and potential health effects.

Summary: This study investigated an outbreak of fatal toxoplasmosis in captive ring-tailed lemurs in Italy in 2009. The lemurs died acutely within a few days and showed necrotic lesions in the spleen, liver, and kidney. Antibody titers, immunohistochemistry, and PCR confirmed the diagnosis of toxoplasmosis and identified the clonal type II. The findings highlight the high susceptibility of ring-tailed lemurs to toxoplasmosis, which poses a threat to the captive population viability.

Summary: Microbial rewilding, a method that modulates or enhances gut microbiomes and improves host-microbe symbiosis through exposure to natural environments, has been found effective in ring-tailed lemurs. The study showed that lemurs transitioned from unnatural to naturalistic environments exhibited increased similarity with wild lemurs' gut communities, decreased proportions of antibiotic resistance genes acquired from human contact during pethood, and greater covariation with soil microbiomes from natural habitats.

Summary: This study investigated the ability of ring-tailed lemurs to detect distant fruit aroma and navigate odor plumes, finding that lemurs could successfully detect the scent of real fruit and track it to the source.

Summary: The study found that enrichment decreased stress-related behaviors in lemurs, while other behaviors were mainly influenced by environmental and individual factors. It highlights the importance of considering these factors together when evaluating enrichment programs for captive animals.

Summary: Primate species show significant variation in behavior and outcomes during intergroup encounters (IGEs), and group and individual characteristics influence engagement and outcomes of IGEs. By studying the IGEs between two small social groups of ring-tailed lemurs, researchers found individual variation in participation and strategies, indicating the importance of considering individual behaviors in understanding IGEs.

Summary: This study documented normal ophthalmic findings and ocular anomalies in captive ringtailed lemurs, establishing reference intervals for the Schirmer tear test-1 (STT) and intraocular pressure (IOP). Ophthalmic abnormalities were noted in 17.5% of eyes, including third eyelid laceration, corneal leukoma, cataracts, chronic uveitis, and vitreous degeneration. These reference intervals and common findings can be useful for clinical veterinarians during eye examinations of ring-tailed lemurs.

Summary: Two 6-year-old ring-tailed lemurs from different zoological institutions were diagnosed with nonpruritic nodules on their eyelids, lips, and chest. The first lemur had severe chronic dermatitis and folliculitis with intralesional Psorobia sp. identified on skin scrapings, while the second lemur had psorergatic mange. Weekly topical applications of amitraz successfully resolved the lesions in both lemurs, with no observed toxicity.

Summary: In this study, the anatomy of the digestive tract in lemurs was quantified, revealing that the increase in intestine length with body mass does not follow the expected geometric scaling pattern, possibly to maintain optimal absorption. Variability in the presence of an appendix in lemurs suggests individual differences, but none were found in the specimens studied here.

Summary: This study investigated the foraging behavior of Zhongwei goats using a step selection function modeling framework, NDVI, vegetation surveys, and GPS tracking. The results showed that the spatial distribution of goats was more influenced by biotic factors than abiotic factors. The goats selected different areas based on the season and availability of preferred forage species. Understanding the patterns and drivers of goats' spatiotemporal distribution is important for predicting livestock foraging behavior and managing semi-arid landscapes.

Summary: This study evaluated bite wound management in captive ring-tailed lemurs and found that poor outcomes were more likely with severe wounds and bite wounds to the hand or limb. Early analgesia is recommended for lemurs with bite wounds.

Summary: This study highlights the sensitivity of gut microbiota to environmental differences at multiple scales in ring-tailed lemurs. The simple dichotomy between captive and wild populations needs to be reevaluated, as the acquisition of environmental microbes may play a role in shaping host-associated consortia. These findings have important implications for animal care, health, and conservation.
