Heterogeneity generated by irregularities on the surface of streambed substrates is an
important determinant of local species diversity of algae. However, few investigators have …

Recent global spread of the freshwater alga Didymosphenia geminata (Didymo) has caused
major biosecurity and freshwater management concerns. Didymo degrades river esthetics …

The benthic, mat‐forming diatomDidymosphenia geminata has the unique ability to produce
large amounts of algal biomass under oligotrophic conditions in cold, fast flowing streams …

Habitat heterogeneity in lotic systems is usually associated with the availability of refuges.
Heterogeneous habitats (here, rough substrata) should mediate the effect of high‐flow …

Freshwater biofilms play an essential ecological role, but they also adversely affect human
activities through undesirable biofouling of artificial submerged structures. They form …

Substrate heterogeneity and biofilm colonization in streams vary across both time and
space, but their relative contribution to reach-scale nutrient uptake is difficult to partition. We …

We measured cell attachments and stalk lengths of the stalked diatom Didymosphenia
geminata in situ, using in vivo staining, under different nutrient (phosphorus and nitrogen) …

Didymosphenia geminata is an alga of major concern in temperate regions due to ongoing
spread and unprecedented bloom formation. The aim of this study was to identify physical …

Increased duration and frequency of droughts under global change may affect both
temporary and formerly permanent watercourses. Streambed desiccation, cooccurring solar …

Didymosphenia geminata is a stalked freshwater diatom, which forms large blooms in ultra-
oligotrophic conditions, and it has been declared a nuisance species in many lotic systems …
