The Influence of Age, Sex, and Season on Hematological Parameters in a Captive Population of Former Laboratory Chimpanzees (Pan troglodytes).

This study aimed to establish a baseline hematological profile and examine the influence of age, sex, and season on hematological parameters in captive chimpanzees (Pan troglodytes) living in a humid tropical climate. Hematological parameters are a useful tool for assessing health status and diagnosing diseases in animals. We analyzed 473 blood samples collected from 84 chimpanzees (43 females and 41 males) during annual health checks, conducted under anesthesia for a routine physical examination.

Cell-type-specific control of secondary cell wall formation by Musashi-type translational regulators in .

Deciphering the mechanism of secondary cell wall/SCW formation in plants is key to understanding their development and the molecular basis of biomass recalcitrance. Although transcriptional regulation is essential for SCW formation, little is known about the implication of post-transcriptional mechanisms in this process. Here we report that two RNA-binding proteins homologous to the animal translational regulator Musashi, MSIL2 and MSIL4, function redundantly to control SCW formation in .

Experimental infection of Artibeus lituratus bats and no detection of Zika virus in neotropical bats from French Guiana, Peru, and Costa Rica suggests a limited role of bats in Zika transmission.

Bats are important natural reservoir hosts of a diverse range of viruses that can be transmitted to humans and have been suggested to play an important role in the Zika virus (ZIKV) transmission cycle. However, the exact role of these animals as reservoirs for flaviviruses is still controversial. To further expand our understanding of the role of bats in the ZIKV transmission cycle in Latin America, we carried out an experimental infection in wild-caught Artibeus lituratus bats and sampled several free-living neotropical bats across three countries of the region.

Species delineation and genetic structure of two species ( and ) on Madagascar and the Comoro archipelago.

Cryptic species diversity is known to be common in bats but remains challenging to study in these mammals, whose natural history traits render their sampling and monitoring challenging. For these animals, indirect genetic approaches provide a powerful tool to gain insight into the evolutionary history and ecology of cryptic bat species. The speciation history of the polyphyletic species group (Molossidae) is poorly understood, including those found on western Indian Ocean islands.
