Latvijas Universitātes Bioloģijas institūta Hidrobioloģijas laboratorijas darbība saistīta ar Latvijas virszemes ūdeņu izpēti. Galvenās pētījumu tēmas ietver:
- kompleksus hidroķīmiskos un hidrobioloģiskos pētījumus Latvijas upēs, ezeros un ūdenskrātuvēs;
- bioloģiskās daudzveidības pētījumus Latvijas saldūdens ekosistēmās;
- biogēno elementu, dabiskas izcelsmes organisko vielu un piesārņojošo vielu plūsmas un ietekmi uz saldūdeņu ekosistēmām.
Laboratorijas personāls ir iesaistīts Latvijas virszemes ūdeņu ekoloģiskās kvalitātes vērtēšanas metožu izstrādē un interkalibrācijā.
Pēdējos gados veikti intensīvi purvu ekosistēmu pētījumi.
Līdzdalība studiju nodrošināšanā
Laboratorijas zinātnieki piedalās LU un studentu maģistra un bakalaura darbu vadīšanā, kā arī studiju kursu docēšanā.
