The identity and nomenclatural history of several smallcelled naviculoid taxa are revisited.
The species discussed here are important from the ecological point of view since they are …

This study aimed to analyse the added value of using ecotoxicological tools to complement
and improve the assessment of natural water bodies status, in situations of climate change …

Diatoms are commonly and frequently used as water quality indicators, but only a few
studies have been done to evaluate the importance of littoral, contemporary diatoms as …

Two new taxa similar to Achnanthidium minutissimum were common and abundant in
samples collected during a survey of benthic diatoms in watercourses from mainland …

Recent morphology-based investigations of freshwater Arctic diatoms suggest that many
species remain to be discovered, reflecting a unique polar flora. During a survey of the …

Mediterranean streams are naturally highly-stressed environments mainly due to wide
seasonal and inter-annual fluctuations in water quantity. This natural pressure will be …

The study of intermittent rivers is a critical and timely issue due to their worldwide increase,
triggered by several causes including climate change. The need to understand the response …

This paper proposes a new monoraphid genus Gliwiczia Kulikovskiy, Lange-Bertalot &
Witkowski, separated from Achnanthes sensu lato. Here we describe four species G …

In the context of global environmental changes, Mediterranean rivers are considered highly
endangered. Temporal and spatial increases of the dry stretches during the summer lead to …

Differences in the structure of diatom assemblages in headwaters with contrasting shading
conditions and different land use in the buffer zone and upper catchment were studied in …
