Abstract:

The goal of this study is to look into the dominance of diatoms, specifically the genus “Pseudo-Nitzschia Sp” at the Nador lagoon level and how it relates to the physicochemical parameters of the environment. From the four sampling stations and for two seasons (spring and summer 2018). This diatom of the genus “Pseudo-Nitzschia Sp” includes toxic species capable of producing domoic acid (DA), a neurotoxin responsible for amnesic intoxication syndrome in humans. During sampling, the species “PseudoNitzschia Sp” showed variable cell densities between stations and seasons. The dominate microalgae

Here, we used single-cell techniques to obtain partial sequences of the parasitoids 18S and cox2 genes.

Abstract:

AbstractThe present communication reports on the occurrence of a multi-species diatom bloom in the upwelled waters along the southwest coast of India. During the late summer monsoon season (September 2009) a multi-species diatom bloom with a pale green discoloration of the sea surface was observed in the coastal waters of southwest coast of India. The bloom spread over an area of approximately 15 km2 along the coastal waters off Kannur (Lat. 11°59.471 N, Long. 75°03.446 E). Total diatom cell density of the bloom area was 16 × 104 cells l−1.

Abstract:

AbstractUnveiling the interactions among phytoplankton and bacteria at the level of species requires axenic isolates to experimentally demonstrate their mutual effects. In this study, we describe the interactions among the diatoms Pseudo‐nitzschia granii and Chaetoceros tenuissimus and their associated bacterial species, isolated from surface water of a coastal upwelling system using coculture experiments. Microalgae growth was assessed in axenic monocultures or in coculture with each of their co‐isolated bacteria in the presence or absence of B vitamins. Pseudo‐nitzschia granii growth was lim

O objetivo deste trabalho foi avaliar os parâmetros ambientais, biomassa, comunidade fitoplanctônica e espécies bioindicadoras, como ferramenta de gestão ambiental na praia Brasília Teimosa, Pernambuco (8º04’S; 34º52’W). Parâmetros abióticos (precipitação, temperatura da água, salinidade, material em suspensão, teor e taxa de saturação do oxigênio, nitrito, nitrato, fosfato e silicato) foram obtidos simultaneamente às coletas de fitoplâncton (garrafa e rede) no período chuvoso (maio; junho e julho/2005) e de estiagem (novembro e dezembro/2005; janeiro/2006). Com exceção dos valores de nitrato

A checklist of phytoplankton species from an anthropogenically pressured ecosystem has become a necessity to study the marine ecosystem changes and to detect the presence of introduced species in the area. This study aimed to list and describe the phytoplankton community in the Tidung, Pari, and Payung Islands and to estimate the total number of phytoplankton species in those islands.

Abstract:

Seasonal phytoplankton blooms are important Arctic phenomena, contributing to global primary production and biogeochemical cycling. The decline in sea-ice extent and thickness favors a longer open-water period with impacts on phytoplankton dynamics. Arctic net productivity is influenced by microalgae living associated with sea ice, with distinct species thought to be favored by ice-covered and ice-free waters. In this study, we investigated the phytoplankton community structure in Baffin Bay, a semi-enclosed sea where Arctic and North Atlantic water masses interact. We compared communities fro
