Littoral chironomids and oligochaetes in the subalpine Lake Maggiore: a first dataset

A dataset of 227 oligochaetes and 373 chironomids occurrence records from the subalpine Lake Maggiore, a large deep temperate lake in Northern-Western Italy Switzerland was developed within Interreg Italy-Switzerland 2014-2020 Parchi Verbano Ticino Project (ID:481668) funded by European Regional Development Fund (ERDF). The belongs to national (LTER-Italy), (LTER-Europe) International (ILTER) long-term ecological research networks. Data were collected during summer-autumn period 2019-2021. Chironomids (Insecta, Diptera) (Annelida, Clitellata) identified genus/species gr./species level authors. All 600 are georeferenced organised standardised Darwin Core Archive format. These data gathered along littoral areas Maggiore will contribute development common implementation strategies for shared sustainable water management lake, with particular reference protected natural (sites belonging Natura 2000 network Emerald Network Switzerland). authors strongly believe great potential open access biogeographical studies context global environmental changes. For that reason, has been uploaded Global Biodiversity Information Facility (GBIF), an intergovernmental free biodiversity infrastructure.
