Asociación o exclusión en la distribución de especies del mismo género en algas unicelulares

Abstract

[EN] The relative occurencies of species of the same genera living together has been used to discuss operation of some ecological mechanisms, between two extremes. If one assumes that to belong to the same genus means actual similarities in ecological needs, and it is accepted further that definite factors have the same key significance for the whole genus, then some association is to be expected, resulting in clusters of congeneric species; [...] Chaetoceros, Ceratium, Cosmarium, Ch. dadayi, Ch. tetrastichon, C. furca [...]

[ES] La frecuencia con que se encuentran juntas especies de un mismo género ha sevido de argumento para debatir los méritos de dos hipótisis distintas: o bien predomina el efecto de la semejanza fisiológica entre especies morfológicamente afines, que conduciría a su coincidencia dentro de un ambiente definido, o bien, por el contrario, la competencia particularmente intensa entre organismos semejantes conduciría a la rígida exclusión de unas especies por otras.
