Nitzschia bergii is a freshwater diatom in the family Bacillariaceae, distinguished by its elongated, narrow valve with a distinctive marginal keel. It is found in benthic communities of rivers and lakes, often associated with slightly enriched conditions.

Nitzschia intermedia is a pennate diatom in the family Bacillariaceae found in freshwater to slightly brackish habitats, where it inhabits both benthic and planktonic niches. Its elongate frustule with a keeled raphe and fine transapical striae is typical of the large genus Nitzschia. It serves as a bioindicator of moderate organic enrichment and nutrient levels in aquatic monitoring programs.
