While many studies have reported that the structure of gut and skin microbiota is driven by both species-specific habitat-specific factors, relative importance host-specific versus environmental factors in wild vertebrates remains poorly understood. The aim this study was to determine diversity composition fish skin, gut, surrounding water bacterial communities (hereafter referred as microbiota) assess extent which host habitat phylogeny predict similarity. Skin swabs samples from 334 belonging 17 species were sampled three Laurentian Great Lakes (LGLs) habitats (Detroit River, Lake Erie, Ontario). We also collected filtered at time collection. analyzed community using 16S metabarcoding tested for variation.We found distinct microbiota, although more closely resembled microbiota.

Annual cycle variations in the gut microbiota of migratory black-necked cranes

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Migratory birds exhibit unique annual cycles that complicate their gut microbiota. However, the dynamics of microbiota in migratory remain unclear, hindering our understanding environmental adaptation. Here, we collected fecal samples from black-necked cranes (Grus nigricollis) across four seasons at breeding grounds and used wintering ground data databases to characterize microbial compositions throughout year. The results showed was clustered by season (Bray-Curtis: R 2 = 0.348, p < 0.001; UniFrac: 0.352, 0.001). And summer exhibited higher alpha (Simpson Shannon), beta diversity (Bray-Curtis UniFrac) more diverse functions compared other seasons. Furthermore, summer, several balanced relative abundances family level, whereas Lactobacillaceae dominated during Thirty-six ASVs were identified random forest analysis distinguish distinct Despite having greater diversity, had a simpler network structure than (fewer edges nodes). dispersal limitation processes also significantly influenced community assembly. Overall, crane undergoes dynamic adjustments adapt seasonal changes, which may be associated with variations diet These enhance wild support further research on cranes.

Physiological differences between wild and captive animals: a century-old dilemma

Journal of Experimental Biology, Год журнала: 2023, Номер 226(23)

Опубликована: Ноя. 30, 2023

ABSTRACT Laboratory-based research dominates the fields of comparative physiology and biomechanics. The power lab work has long been recognized by experimental biologists. For example, in 1932, Georgy Gause published an influential paper Journal Experimental Biology describing a series clever experiments that provided first empirical test competitive exclusion theory, laying foundation for field remains active today. At time, wrestled with dilemma conducting or field, ultimately deciding progress could be best achieved taking advantage high level control offered experiments. However, physiological often yield different, even contradictory, results when conducted versus settings. This is especially concerning Anthropocene, as standard laboratory techniques are increasingly relied upon to predict how wild animals will respond environmental disturbances inform decisions conservation management. In this Commentary, we discuss several hypothesized mechanisms explain disparities between biology field. We propose strategies understanding why these differences occur can use improve our animals. Nearly century beyond Gause's work, still know remarkably little about what makes captive different from ones. Discovering should important goal biologists future.

ABSTRACT Microbiome science has provided groundbreaking insights into human and animal health. Similarly, evolutionary medicine – the incorporation of eco‐evolutionary concepts primarily medical theory practice is increasingly recognised for its novel perspectives on modern diseases. Studies host–microbe relationships have been expanded beyond humans to include a wide range taxa, adding new facets our understanding ecology, evolution, behaviour, In this review, we propose that broader application medicine, combined with microbiome science, can provide valuable innovative care conservation. First, draw classic ecological principles, such as alternative stable states, an framework variation in microbiomes their role health wellbeing. With focus mammalian gut microbiomes, apply populations animals under care, particular relevance many species suffer diseases linked microbial dysfunction (e.g. distress infection, autoimmune disorders, obesity).

Environmental shifts and dietary habits could directly affect the gut microbiota of animals. In this study, we investigated golden snub-nosed monkeys under two different conditions: captive wild. Our study adopted a non-invasive sampling method, using full-length 16S rRNA Pacbio SMAT sequencing technology to compare wild monkeys. The results showed that populations had higher alpha diversity than populations, there were also significant differences in beta diversity. linear discriminant analysis effect size (LEfSe) 39 distinctly taxonomic units.

Abstract The wild-born long-tailed macaques ( Macaca fascicularis ) were recently recruited and used as breeders for the National Primate Research Center of Thailand, Chulalongkorn University (NPRCT-CU), changes in their in-depth gut microbiota profiles investigated. Oxford Nanopore Technology (ONT) was to explore full-length 16S rDNA sequences animals once captured natural habitat 1-year following translocation housing a hygienic environment at NPRCT-CU. Our findings show that after 1 year programmed diets feeding altered reshaped. prevalent bacteria such Prevotella copri Faecalibacterium prausnitzii enriched translocation, causing lower alpha diversity. correlation analysis revealed , Phascolarctobacterium succinatutens stercorea showed positive with each other.

ABSTRACT Reptiles and amphibians (herptiles) are some of the most endangered threatened species on planet numerous conservation strategies being implemented with goal ensuring recovery. Little is known, however, about gut microbiome wild herptiles how it relates to health these populations. Here, we report results from characterization both a broad survey herptiles, correlation between fungus Basidiobolus , bacterial community supported by deeper, more intensive sampling Plethodon glutinosus known as slimy salamanders. We demonstrate that communities sampled frogs, lizards, salamanders structured host taxonomy common natural component microbiomes. Intensive multiple hosts across ecoregions Tennessee revealed geography host:geography interactions strong predictors distinct operational taxonomic units present within given host. Co-occurrence analyses diversity support interaction bacteria, suggesting may play role in structuring community. further hypothesis this advanced unique specialized metabolism originating horizontal gene transfer bacteria capable producing metabolites including small cyclic peptides.
