Population genetics of captive spider monkeys in Japan for ex situ conservation
Reduction of bitter taste receptor gene family in folivorous colobine primates relative to omnivorous cercopithecine primates
Bitter taste perception is important in preventing animals from ingesting potentially toxic compounds. Whole-genome assembly (WGA) data have revealed that bitter taste receptor genes ( TAS2R s) comprise a multigene family with dozens of intact and disrupted genes in primates. However, publicly available WGA data are often incomplete, especially for multigene families. In this study, we employed a targeted capture (TC) approach specifically probin…
Diet‐related factors strongly shaped the gut microbiota of Japanese macaques
Although knowledge of the functions of the gut microbiome has increased greatly over the past few decades, our understanding of the mechanisms governing its ecology and evolution remains obscure. While host genetic distance is a strong predictor of the gut microbiome in large‐scale studies and captive settings, its influence has not always been evident at finer taxonomic scales, especially when considering among the recently diverged animals in n…
Comparative analysis of sperm motility in liquid and seminal coagulum portions between Bornean orangutan (Pongo pygmaeus) and chimpanzee (Pan troglodytes)
Female chimpanzees giving first birth in their natal group in Mahale
Daosheng’s Understanding of the Lotus Sūtra
This paper focuses on the interpretation of the “One Vehicle of the Lotus Sūtra”, a concept created by Zhu Daosheng 竺道生 (355?–434), a disciple of Kumārajīva (344–413 or 350–409). Daosheng’s interpretation of the Lotus Sūtra is based on the viewpoint of 6 factors: “Cause”, “Effect”, “People”, “Teaching”, “Noumenal Principle”, and “Salvific Impetus”. In addition, he implemented his interpretation of the Lotus Sūtra by the theory that the bodhisattv…
Stomach and colonic microbiome of wild Japanese macaques
Within the gastrointestinal tract, the physiochemical microenvironments are highly diversified among the different stages of food digestion. Accordingly, gut microbiome composition and function vary at different gut sites. In this study, we examine and compare the compositional and functional potential between the stomach and colonic microbiome of wild Japanese macaques ( Macaca fuscata yakui ) living in the evergreen forest of Yakushima Island. …
Evolution of the bitter taste receptor TAS2R38 in colobines
Gut microbiota composition of Japanese macaques associates with extent of human encroachment
In recent decades, human–wildlife interaction and associated anthropogenic food provisioning has been increasing and becoming more severe due to fast population growth and urban development. Noting the role of the gut microbiome in host physiology like nutrition and health, it is thus essential to understand how human–wildlife interactions and availability of anthropogenic food in habitats can affect an animal's gut microbiome. This study, theref…
