Tintinnids from Todos Santos Bay, B.C., Mexico (1980-1985). I. Taxonomy

Tintinnids from Todos Santos Bay, Baja California (Mexico), were collected from 1980 to 1985 by means of 83 horizontal surface tows with a standard No. 20 net (75 µm mesh size). Based on lorica morphology, 66 species and 30 genera were identified. Ten species are considered as permanent due to their...

Taxonomy Tintínidos de la Bahía de Todos Santos, B.C., México (1980-1985). I. Taxonomía Santamaría-del-Ángel, E Orellana-Cepeda, E n/a n/a Tintinnids from Todos Santos Bay, Baja California (Mexico), were collected from 1980 to 1985 by means of 83 horizontal surface tows with a standard No. 20 net (75 µm mesh size). Based on lorica morphology, 66 species and 30 genera were identified. Ten species are considered as permanent due to their presence in plankton during at least four years. Other records include: two cold-water, five tropical and two cosmopolitan species. Such an assembly suggests that the bay is subject to changing conditions. A key to the genera is presented with 70 light microscope photographs, 41 SEM pictures and seven line drawings. Remarks on synonymy, specific taxonomic characters and polymorphism are included. Ultrastructure observations proved to be of great aid in these forementioned aspects. The high diversity suggests that Todos Santos Bay harbors several different microhabitats. Entre los años de 1980 y 1985, en la Bahía de Todos Santos, Baja California (México), se realizaron 83 arrastres superficiales con una red estándar de plancton No. 20 (75 µm de luz de malla), con el propósito de realizar un reconocimiento taxonómico de los tintínidos. En base a la morfología de la lóriga, se lograron identificar 66 especies pertenecientes a 30 géneros. Se pudieron caracterizar diez especies “permanentes” debido a que su ocurrencia en el plancton se mantuvo al menos durante cuatro años de estudio. Se reconocieron dos especies propias de aguas frías. cinco de regiones tropicales y dos cosmopolitas como posibles especies indicadoras de los cambios e influencias que recibe la bahía. Se elaboró una llave de identificación de los géneros que se presentan en la bahía, que se ilustra con 70 fotografías tomadas al microscopio compuesto, 41 al microscopio de barrido y siete dibujos. Se discute acerca de sinonimia y de caracteres taxonómicos específicos, destacando los fenómenos de polimorfismo. Se concluye que el estudio de la infraestructura contribuye al esclarecimiento de estos problemas. Una hipótesis que se deriva de este trabajo, es que la Bahía de Todos Santos presenta una alta diversidad debida a la gran cantidad de microhabitats que abriga.
