The main effects of anthropogenic transformations are hydrological changes, such as lower current velocity or an increase of nutrient content, and higher temperature. Zooplankton reacts rapidly to the new environmental conditions in rivers, increasing its richness and abundance. We tried to answer two questions: what type of catchment use has a greater influence on the zooplankton communities in a river and how do dam impoundments influence the zooplankton communities downstream? The study was conducted in the Corgo river (drainage of the Douro river, Northern Portugal) at 17 sampling sites in the lotic, free-flowing sections. Crustaceans present in the Corgo can attain relatively high densities in the rural section, which offers them better trophic conditions. The urban catchment use and the presence of dams have a greater impact on the rotifer density and the increase of zooplankton density downstream. The results of this study confirm that zooplankton properties allow for the evaluation of the degree of river-bed transformation.<\/jats:p>","DOI":"10.3390\/ijerph16010020","type":"journal-article","created":{"date-parts":[[2018,12,21]],"date-time":"2018-12-21T09:24:11Z","timestamp":1545384251000},"page":"20","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["The Impact of Land Use Transformations on Zooplankton Communities in a Small Mountain River (The Corgo River, Northern Portugal)"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0064-006X","authenticated-orcid":false,"given":"\u0141ukasz","family":"S\u0142ugocki","sequence":"first","affiliation":[{"name":"Department of Hydrobiology and General Zoology, Faculty of Biology, University of Szczecin, 71-712 Szczecin, Poland"},{"name":"Centre of Molecular Biology and Biotechnology, University of Szczecin, 71-712 Szczecin, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7785-087X","authenticated-orcid":false,"given":"Robert","family":"Czerniawski","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology and General Zoology, Faculty of Biology, University of Szczecin, 71-712 Szczecin, Poland"},{"name":"Centre of Molecular Biology and Biotechnology, University of Szczecin, 71-712 Szczecin, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9614-2000","authenticated-orcid":false,"given":"Monika","family":"Kowalska-G\u00f3ralska","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology and Aquaculture, Wroc\u0142aw University of Environmental and Life Sciences, 51-630 Wroc\u0142aw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3343-1021","authenticated-orcid":false,"given":"Magdalena","family":"Senze","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology and Aquaculture, Wroc\u0142aw University of Environmental and Life Sciences, 51-630 Wroc\u0142aw, Poland"}]},{"given":"Anabela","family":"Reis","sequence":"additional","affiliation":[{"name":"Department of Geology, University of Tr\u00e1s-os-Montes e Alto Douro, 5001-801 Vila Real, Portugal"},{"name":"Centre for Mechanical Engineering, Materials and Processes, University of Coimbra, 3000-079 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5636-9400","authenticated-orcid":false,"given":"Jo\u00e3o S.","family":"Carrola","sequence":"additional","affiliation":[{"name":"Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1680-8405","authenticated-orcid":false,"given":"Carlos A.","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, 5001-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1503","DOI":"10.1139\/f04-088","article-title":"Importance of landscape variables and morphology on nutrients in Missouri reservoirs","volume":"61","author":"Jones","year":"2004","journal-title":"Can.
