GUÍA PARA EL ESTUDIO DE LOS SERES VIVOS EN AGUAS DULCES
Needham J.G.
El objetivo de la presente obra es facilitar el reconocimiento de los organismos vivos de las aguas dulces, tanto en el laboratorio como en la propia naturaleza. Solo están incluidos es esta obra los organismos que se encuentran comúnmente en las aguas dulces; no se tratan los habitantes de aguas saladas, salobres o alcalinas. Las plantas vasculares han sido también omitidas. Los nombres genéricos están referidos en el sentido de grupos de especies, de manera que un principiante sea capaz de reconocerlos por diferencias externas.
