The activity of these animals promotes biodiversity and water purification processes, but can also lead to the accumulation of pollutants. Water retention in beaver ponds promotes the development of bacteria and other microorganisms that play an important role in biogeochemical cycles. Long\u2010term water stagnation can lead to anaerobic conditions and the formation of toxic compounds, which in turn can limit the diversity of benthic organisms. Beavers play a key role in shaping these habitats, and microbiological studies of their reservoirs provide a better understanding of their impact on aquatic ecosystems, self\u2010purification processes and potential biological threats. Metagenomic analysis revealed the presence of 365 bacterial species in water and sediment samples, belonging to 174 genera and 83 families. 83 operational taxonomic units (OTUs) were identified, 62 of which were present in both water and sediments. Although the overall OTU composition was similar in both environments, greater variability was observed in the sediments. The statistical differences in OTU distribution between water and sediments were confirmed using the Wilcoxon test.<\/jats:p>","DOI":"10.1002\/ece3.72790","type":"journal-article","created":{"date-parts":[[2025,12,25]],"date-time":"2025-12-25T22:57:36Z","timestamp":1766703456000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dependence of Bacterial\n                    <scp>OTUs<\/scp>\n                    on Selected Features of Beaver Ponds"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2671-1842","authenticated-orcid":false,"given":"Micha\u0142","family":"Wr\u00f3bel","sequence":"first","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3432-3097","authenticated-orcid":false,"given":"Rados\u0142aw","family":"Gawry\u015b","sequence":"additional","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0509-9604","authenticated-orcid":false,"given":"Anna","family":"Tereba","sequence":"additional","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5737-1951","authenticated-orcid":false,"given":"Magdalena","family":"Fr\u0105k","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing and Environmental Assessment, Warsaw University of Life Sciences  Warsaw Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3215-5934","authenticated-orcid":false,"given":"Katarzyna","family":"Sikora","sequence":"additional","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1270-0656","authenticated-orcid":false,"given":"Karol","family":"Soko\u0142owski","sequence":"additional","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7119-0452","authenticated-orcid":false,"given":"Andrzej","family":"Boczo\u0144","sequence":"additional","affiliation":[{"name":"Department of Forest Ecology, Forest Research Institute  S\u0119kocin Stary Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,25]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1128\/mr.59.1.143-169.1995"},{"key":"e_1_2_10_3_1","first-page":"288","volume-title":"Wild Mammals of North America: Biology, Management, and Conservation","author":"Baker B.
