To understand the composition and drivers of zooplankton gut microbiota, we investigated the associated microbial communities of four zooplankton genera from different seasons in the Baltic Sea using the 16S rRNA gene. Among the 143 ASVs (amplified sequence variants) observed belonging to heterotrophic bacteria, 28 ASVs were shared across all zooplankton hosts over the season, and these shared core ASVs represented more than 25% and up to 60% of relative abundance in zooplankton hosts but were present at low relative abundance in the filtered water. Zooplankton host identity had stronger effects on bacterial composition than seasonal variation, with the composition of gut bacterial communities showing host-specific clustering patterns. Although bacterial compositions and dominating core bacteria were different between zooplankton hosts, higher gut bacteria diversity and more bacteria contributing to the temporal variation were found in Temora and Pseudocalanus, compared to Acartia and Synchaeta. Diet diatom and filamentous cyanobacteria negatively correlated with gut bacteria diversity, but the difference in diet composition did not explain the dissimilarity of gut bacteria composition, suggesting a general effect of diet on the inner conditions in the zooplankton gut. Synchaeta maintained high stability of gut bacterial communities with unexpectedly low bacteria-bacteria interactions as compared to the copepods, indicating host-specific regulation traits. Our results suggest that the patterns of gut bacteria dynamics are host-specific and the variability of gut bacteria is not only related to host taxonomy but also related to host behavior and life history traits.", "doi": "10.1007/s00248-024-02362-7", "pmid": "38409540", "labels": {"NGI Short read": "Service", "NGI Stockholm (Genomics Production)": "Service", "National Genomics Infrastructure": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC10896951"}, {"db": "pii", "key": "10.1007/s00248-024-02362-7"}], "notes": [], "created": "2024-03-14T11:09:50.360Z", "modified": "2024-11-25T10:10:49.264Z"}, {"entity": "publication", "iuid": "236e229a33f94e5cbbd5fca21439b072", "links": {"self": {"href": "https://publications.scilifelab.se/publication/236e229a33f94e5cbbd5fca21439b072.json"}, "display": {"href": "https://publications.scilifelab.se/publication/236e229a33f94e5cbbd5fca21439b072"}}, "title": "DNA metabarcoding reveals trophic niche diversity of micro and mesozooplankton species.", "authors": [{"family": "Novotny", "given": "Andreas", "initials": "A", "orcid": "0000-0001-8910-6183", "researcher": {"href": "https://publications.scilifelab.se/researcher/2c63db5be95c40e49940affadc958928.json"}}, {"family": "Zamora-Terol", "given": "Sara", "initials": "S", "orcid": "0000-0002-7822-3197", "researcher": {"href": "https://publications.scilifelab.se/researcher/25e1b401fc9a49c5b6f89eaa18f89a57.json"}}, {"family": "Winder", "given": "Monika", "initials": "M"}], "type": "journal article", "published": "2021-06-30", "journal": {"title": "Proc.

Nevertheless, the complexity of zooplankton interactions is rarely considered in trophic studies because of the lack of detailed information about feeding interactions in nature. In this study, we used DNA metabarcoding to highlight the diversity of trophic niches in a wide range of micro- and mesozooplankton, including ciliates, rotifers, cladocerans, copepods and their prey, by sequencing 16- and 18S rRNA genes. Our study demonstrates that the zooplankton trophic niche partitioning goes beyond both phylogeny and size and reinforces the importance of diversity in resource use for stabilizing food web efficiency by allowing for several different pathways of energy transfer. We further highlight that small, rarely studied zooplankton (rotifers and ciliates) fill an important role in the Baltic Sea pelagic primary production pathways and the potential of ciliates, rotifers and crustaceans in the utilization of filamentous and picocyanobacteria within the pelagic food web. The approach used in this study is a suitable entry point to ecosystem-wide food web modelling considering species-specific resource use of key consumers.", "doi": "10.1098/rspb.2021.0908", "pmid": "34130506", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Production)": "Service", "NGI Stockholm (Genomics Applications)": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC8206686"}, {"db": "Dryad", "key": "10.5061/dryad.gb5mkkwpw"}, {"db": "figshare", "key": "10.6084/m9.figshare.c.5448706"}], "notes": [], "created": "2021-10-01T09:02:29.362Z", "modified": "2024-01-16T13:48:39.416Z"}]}
