The west coast of the Baja California peninsula is
one of most productive marine regions of Mexico.
Oceanographic processes promote the formation
of algae blooms in the region. Algae blooms may
become harmful (HAB) when toxin-producing
species are present or the accumulation of bio-
mass deteriorate environmental conditions that
can affect oth...
La ecofisiología busca entender el efecto de las variables bióticas y abióticas sobre el crecimiento, reproducción, supervivencia, abundancia y distribución de las especies. Los estudios sobre ecofisiología son fundamentales para caracterizar el crecimiento y producción de toxinas de especies fitoplanctónicas potencialmente nocivas y así entender l...
La Red Temática sobre Florecimientos Algales Nocivos (RedFAN) fue creada bajo el marco de la convocatoria 2014 del Consejo Nacional de Ciencia y Tecnología (CONACYT). La RedFAN agrupa a investigadores que realizan estudios sobre los florecimientos algales nocivos (FAN) en México y estudiantes con proyectos de investigación en el área. Asimismo, inc...
Sedimentos recientes en costas mexicanas contienen quistes de resistencia de dinoflagelados, los cuales son más abundantes durante y al final de sus florecimientos. Los quistes se acumulan en aguas someras asociadas a sedimentos finos con un intervalo de tamaño de 31 a 125 μm, y funcionan como “semilleros”. Al resuspenderse, los quistes detectan la...
This study analyzes the temporal variability of the abundance of Lingulodinium polyedrum and Scrippsiella trochoidea resting cysts in surface sediments, as well as the temporary cysts and vegetative cells of L. polyedrum in the upper water column of Todos Santos Bay (Baja California, Mexico). Samples were collected monthly from January 2002 to June...

A toxic Pseudo-nitzschia spp. bloom in the Todos Santos Bay area (31.8°N), Mexico, is described. This is the southernmost report of the presence of domoic acid (DA) in the California Current System and it is also the first report of the distribution of toxic Pseudo-nitzschia species and DA on the Baja California west coast. The maximum cell abundan...
A biometrical analysis of the dinoflagellate cyst Lingulodinium machaerophorum [Deflandre, G., Cookson, I.C., 1955. Fossil microplankton from Australia late Mesozoic and Tertiary sediments. Australian journal of Marine and Freshwater Research 6: 242–313.] Wall, 1967 in 144 globally distributed surface sediment samples revealed that the average proc...
Algal blooms for the period of 2000 and 2001 at Banderas Bay, México, were analyzed from SeaWiFS-ocean-color-sensor derived information. These events were related with the maximum chlorophyll week anomalies (ASi; a proxy variable constructed for the analysis of chlorophyll temporal variation in the bay). The winter-spring blooms were multispecific,...
Algal blooms at Banderas Bay, México (2000-2001), from SeaWiFS-sensor-data. Algal blooms for the period of 2000 and 2001 at Banderas Bay, México, were analyzed from SeaWiFS-ocean-color-sensor derived information. These events were related with the maximum chlorophyll week anomalies (ASi; a proxy variable constructed for the analysis of chlorophyll...
Forty-two species of dinoflagellate motile cells and 18 species of organic-walled dinoflagellate resting cysts were identified in samples collected at Todos Santos Bay, Baja California, México, from September 1999 to June 2000. These temperate to cool-temperate species belong mainly to the families Gonyaulacaceae and Protoperidiniaceae. Lingulodini...
Dinoflagellate cysts with dinosporin walls were identified for the first time in samples collected at Todos Santos Bay, Baja California, Mexico, during winter-spring 2000. Eighteen neritic species characteristic of temperate to temperate-cool neritic regions were identified, mainly from the Gonyaulacaceae and Congruentidiaceae families. The cysts w...
