Eutrophication is one of the most widespread causes of biotic homogenization in freshwater
ecosystems. Biotic homogenization can be characterized as reductions in local diversity …

Knowledge of biodiversity in oligotrophic aquatic ecosystems is fundamental to plan
conservation strategies for protected areas. This study assessed the diatom diversity from an …

This research uses the techniques of light and scanning electron microscopy to observe two
species of Achnanthidium Kützing belonging to the A. minutissimum 'sensu lato'complex …

Background and aims–Two unknown benthic diatom species belonging to the genus
Achnanthidium Kütz., and found in French and Nepalese freshwater habitats, were …

Pseudostaurosira crateri sp. nov. is described from fossil material analyzed from a
Quaternary sediment core retrieved from the Colônia basin (located in the Brazilian Coastal …

Abstract We developed the Trophic Diatom Index for Reservoirs (TDIR), the first index
proposal for water trophic quality assessment of tropical reservoirs in Brazil. Furthermore, we …

The present study aims to expand the knowledge on Achnanthidium species occurring in
tropical areas of southern Brazil. For this purpose, 345 samples from 179 sampling sites …

A new monoraphid diatom species appeared successively in paleolimnological records from
a Quaternary sediment core (1.5±0.1 Ma) retrieved from Colônia basin (Brazilian Coastal …

Turkish lakes have different morphometric and hydrological features as a result of different
climates and noticeable altitude differences in Turkey that are necessary conditions to occur …

In order to access environmental conditions, the use of bioindicators that have a close
relationship with environmental stressors is a largely common practice, but when evaluating …
