@article { , title = {Characterisation of the effect of day length, and associated differences in dietary intake, on the gut microbiota of Soay sheep.}, abstract = {Differences in the rumen bacterial community have been previously reported for Soay sheep housed under different day length conditions. This study extends this previous investigation to other organs of the digestive tract, as well as the analysis of ciliated protozoa and anaerobic fungi. The detectable concentrations of ciliated protozoa and anaerobic fungi decreased with increased day length in both the rumen and large colon, unlike those of bacteria where no effect was observed. Conversely, bacterial community composition was affected by day length in both the rumen and large colon, but the community composition of the detectable ciliated protozoa and anaerobic fungi was not affected. Day length associated differences in the bacterial community composition extended to all of the organs examined, with the exception of the duodenum and the jejunum. It is proposed that differences in rumen fill and ruminal ‘by-pass’ nutrients together with endocrinological changes cause the observed effects of day length on the different gut microbial communities.}, doi = {10.1007/s00203-019-01652-w}, eissn = {1432-072X}, issn = {0302-8933}, issue = {7}, journal = {Archives of microbiology}, note = {INFO COMPLETE (Now fully published, checked 19/8/2019 LM -- Info via GB (Springer offset) 26/3/2019 LM) PERMISSION GRANTED (version = VoR; embargo = none; licence = BY; SHERPA = http://sherpa.mimas.ac.uk/romeo/issn/0302-8933/ DOCUMENT RECIEVED (AAM rec'd from contact 29/3/2019 but check for VOR on upload 8/4/2019 LM)}, pages = {889-896}, publicationstatus = {Published}, publisher = {Springer}, url = {https://rgu-repository.worktribe.com/output/235745}, volume = {201}, keyword = {Soay sheep, Digestive tract, Bacteria, Anaerobic fungi, Ciliated protozoa, Day length}, year = {2019}, author = {Thomas, Nadine A. and Olvera-Ramirez, Andrea M. and Abecia, Leticia and Adam, Clare L. and Edwards, Joan E. and Cox, Georgina F. and Findlay, Patricia A. and Destables, Elodie and Wood, Tracy A. and McEwan, Neil R.} }
