Gut microbiota composition and metabolomic profiles of wild and captive Chinese monals (Lophophorus lhuysii)

Abstract: Background The Chinese monal (Lophophorus lhuysii) is an endangered bird species, with a wild population restricted to the mountains in southwest China, and only one known captive population in the world. We investigated the fecal microbiota and metabolome of wild and captive Chinese monals to explore differences and similarities in nutritional status and digestive characteristics. An integrated approach combining 16S ribosomal RNA (16S rRNA) gene sequencing and ultra-high performance liquid ch… Show more

“…An often mentioned criticism on the microbiome analysis of zoo animals is the fact that captivity might lead to a reduced microbial alpha diversity in some species [ 67 , 68 ]. Reasons for this may include a different dietary composition, the use of additives and medicines, or the artificial enclosure design.…”

“…Such inconsistencies raise questions about the widely held view that wild populations have greater alpha diversity. For instance, the alpha diversity was significantly higher in wild populations of certain birds, including the oriental white stork ( Ciconia boyciana ) ( 28 ) and the Chinese monal ( Lophophorus lhuysii ) ( 70 ), when compared to their counterparts in captivity. Greatest alpha diversity was also found in some other wild mammals, such as alpine musk deer ( Moschus chrysogaster ) ( 71 ), bharals ( Pseudois nayaur ) ( 72 ), snub-nosed monkeys ( Rhinopithecus roxellana ) ( 73 ), deer mice ( Peromyscus maniculatus ) ( 74 ), the Przewalski’s Horse ( Equus ferus przewalskii ), and the Asian wild ass ( Equus hemionus ) ( 75 ), while the captive ones had the least alpha diversity.…”

“…This is similar to previous observations that found wild animals to exhibit greater gut microbiota richness than those in captivity because animals in the wild can forage freely with access to diverse food types and sources. Furthermore, the abundant food sources could promote higher diversity colonization of gut microbiota ( Passos et al, 2018 ; Chi et al, 2019 ; Jiang et al, 2020 ).…”
