Synopsis nach oben ↑
The authors of this volume study and describe the valve morphology of
108 taxa, representing 75 distinct species, in the genera
Amphora and Halamphora from aquatic environments in the
United States and Japan. Amphora Ehrenberg ex Kützing and
Halamphora (Cleve) Levkov are taxonomically diverse genera of
raphid diatoms. In addition to being species rich, their ecology is
equally diverse, with representatives of the genera present in coastal
and inland waters from the tropics to the arctic.
Of the 75 species, nearly one-half of them (33) are described as new,
including 4 from the genus Amphora and 29 from the genus
Halamphora. Eight species are transferred from Amphora
to Halamphora and new combinations proposed. All taxa
considered herein have been cultured, and 4 genes (the nuclear encoded
18S and 28S rDNA and the chloroplast encoded rbcL and psbC genes) have
been sequenced for each.
This combination of morphological and molecular data lays an important
foundation for future research of the taxonomy, ecology and
systematics of the Amphora and Halamphora floras of
coastal and inland waters.
