Differences in the gut microbiota between Cercopithecinae and Colobinae in captivity

The gut microbiome of captive primates can provide a window into their health and disease status. The diversity and composition of gut microbiota are influenced by not only host phylogeny, but also host diet. Old World monkeys (Cercopithecidae) are divided into two subfamilies: Cercopithecinae and Colobinae. The diet and physiological digestive features differ between these two subfamilies. Accordingly, highthroughput sequencing was used to examine gut microbiota differences between these two subfamilies, using data from 29 Cercopithecinae individuals and 19 Colobinae individuals raised in captivity. Through a comparative analysis of operational taxonomic units (OTUs), significant differences in the diversity and composition of gut microbiota were observed between Cercopithecinae and Colobinae. In particular, the gut microbiota of captive Old World monkeys clustered strongly by the two subfamilies. The Colobinae microbial diversity was higher than that of Cercopithecinae. Additionally, Firmicutes, Lactobacillaceae, Veillonellaceae, and Prevotella abundance were higher in Cercopithecinae, while Bacteroidetes, Ruminococcaceae, Christensenellaceae, Bacteroidaceae, and Acidaminococcaceae abundance were higher in Colobinae. PICRUSt analysis revealed that the predicted metagenomes of metabolic pathways associated with proteins, carbohydrates, and amino acids were significantly higher in Colobinae. In the context of host phylogeny, these differences between Cercopithecinae and Colobinae could reflect adaptations associated with their respective diets. This well-organized dataset is a valuable resource for future related research on primates and gut microbiota. Moreover, this study may provide useful insight into animal management practices and primate conservation.

Leaf-rolling weevils (Coleoptera: Atelabidae) are considered to be specialists that oviposit only on one or two plant species. However, Apoderus dimidiatus can oviposit on at least five species. We aimed to determine whether A. dimidiatus females have different preferences for oviposition substrates, and whether differences in physical factors, nutrition and parasitism affected their choices. We observed the number of cradles, hatched larvae, pupae, emerging adults and parasitism rate during one breeding season. Weevils were given access to two host plant species, Rosa multiflora and Rubus ichangensis, and the leaf size and nutrient contents of the two plant species were investigated. We found that nutritional content, especially soluble carbohydrate, correlated with oviposition preference of weevils, and the more nutritious plant species, R. multiflora, was the preferred host in our experiment. Weevils can also use Ru. ichangensis and other plant species as hosts, likely to relieve the high parasitic pressure when laying eggs on a single host species.
