Rare interspecific breeding in Pseudo-nitzschia (Bacillariophyceae)

Phytotaxa, 2015
The biological species concept defines species based on sexual incompatibility between strains and the F1 sub-viability or inviability. However, to date, there is only a limited number of studies that formally deal with sexual incompatibility in unicellular protists and hence the rigorous application of biological species concept is fuzzy in these ...

Revision ofAmphora holsatica(Bacillariophyceae)

European Journal of Phycology, 2003
Material chosen as the lectotype of Amphora holsatica Hustedt and others of the type series has been examined using light and electron microscopy, and a more comprehensive concept of A. holsatica was established through an expansion of its description. In light of this new description comparisons with the related A.

Cymbellonitzschia diluviana Hustedt (Bacillariophyceae): Habitat and auxosporulation

Hydrobiologia, 1993
The diatom Cymbellonitzschia diluviana Hustedt is an important indicator species in interglacial deposits but is rarely reported from contemporary sites. The presence of large populations in Lough Neagh, N. Ireland, made possible a study of its ecology and auxosporulation.

Observations on Navicula okunoi Hustedt (Bacillariophyceae)

Phycologia, 1988
Abstract Navicula okunoi Hustedt was described from a Miocene freshwater deposit near Setana, Japan. The holotype and so far only known specimen of this taxon has been destroyed. Recent thorough research revealed several specimens among which a neotype was designated. This investigation also showed that the taxon belongs in the genus Achnanthes.

Bacillariophyceae u epifitonskim zajednicama ljutka

1999
Tijekom 1997. i 1998. godine u NP Plitvička jezera, provedena su sustavna istraživanja alga kremenjašica u epifitonskim zajednicama na živim i uginulim stabljikama ljutka (Cladium mariscus Pohl.). Ukupno je determinirano 137 vrsta od kojih je 50% zajedničkih na oba tipa supstrata. Na živim stabljikama ljutka determinirano je 96, a na uginulim 111 vrsta.
