| dc.description.abstract | Nanoplankton collected from April 1990 to April 1991 from surface water of Saanich Inlet, British Columbia was examined with transmission and scanning electron microscopy. Eighty species were identified. These belonged to the algal Classes Pedinophyceae, Prasinophyceae, Pryrnnesiophyceae and Chrysophyceae and the protistan Order Choanoflagellida and Class Heliozoea. Fifty of these are new published records for the west coast of North America. New taxonomic findings were a variation of Triparma columacea, a new scale type from Cymbomonas, two undescribed prasinophyte scale types and an unusual number of lorica costae in Polyfibula stipitata. Summer nanoplankton was characterized by high species numbers of autotrophic Prasinophyceae and Prymnesiophyceae. Prasinophytes were almost entirely absent in winter months. Winter nanoplankton populations varied between translocated freshwater species and marine and brackish species, most of which were heterotrophic chrysophytes and choanoflagellates. Low species numbers with similar species composition was seen in April of both years. Speculations on causes of species succession are made. | |
