Competition among phytoplankton for limiting resources may involve direct or indirect interactions. A direct interaction of competitors is the release of chemicals that inhibit other species, a process known as allelopathy. Here, we investigated the allelopathic effect of three toxic microalgae species (Alexandrium tamarense, Karenia mikimotoi and Chrysochromulina polylepis) on a natural popula...

Studies on dinoflagellate cysts provide important knowledge the ecology of dinoflagellates and harmful algal blooms (HABs). In this study, distribution abundance in surface sediments from 17 stations at Van Phong Bay were analyzed. There 55 different types representing 3 orders 18 genera, 8 unidentified cyst recorded. Peridiniales was most diverse order with 29 types, including 20 Protoperidini...

Outcrop samples were collected from Dukku area for the purpose of subjecting them to palynological analysis in order determine relative age Gwandu Formation and palaeoenvironment deposition deposit. Field laboratory methods carried out obtain lithological sequence description outcrop. The obtained went through processes acid digestion with hydrochloric acid, hydrofluoric separation macerals by ...
