Approximately two decades after the first pioneering analyses, the study of shape asymmetry
with the methods of geometric morphometrics has matured and is a burgeoning field. New …

Diatoms play a key role in the functioning of streams, and their sensitivity to many
environmental factors has led to the development of numerous diatom-based indices used …

Diatoms are main bioindicators used to assess the ecological quality of rivers, but their
identification is difficult and time-consuming. Next Generation Sequencing (NGS) can be …

Background Studies of symmetric structures have made important contributions to
evolutionary biology, for example, by using fluctuating asymmetry as a measure of …

This paper provides a step-by-step guide for the morphological analysis of corolla and the
decomposition of corolla shape variation into its symmetric and asymmetric components …

Algal taxonomy is a key discipline in phycology and is critical for algal genetics, physiology,
ecology, applied phycology, and particularly bioassessment. Taxonomic identification is the …

Over the last years, issues concerning diatom teratological forms and environmental stress
have received growing interest within the scientific community. Publications on this topic …

Diatoms are regularly used for bioassessment and ecotoxicological studies in relation to
environmental and anthropogenic disturbances. Traditional taxonomical diatom parameters …

Diatoms from the genus Achnanthidium are abundant in rivers, streams, and springs of the
Appalachian Mountains. They inhabit clean and polluted waters, including those affected by …

Our study evaluates differences in the distribution and ecology of genetic variants within
several ecologically important diatom species that are also key for Water Framework …
