Fine structure of the epidermal cuticle of some Brazilian earthworms (Oligochaeta: Annelida).
The authors conducted laboratory experiments to investigate the effects of the exposure to a sublethal concentration of lead on the ultrastructure and acid phosphatase compartmentalization of the chloragogenous tissue of earthworms (Eisenia foetida).
The authors determined the presence and distribution of earthworms in the "Reserva Hidrica Dique La Quebrada", a hydraulic dam reserve in the province of Cordoba, Argentina.
The authors carried out a cytogenetical study on the chromosomes and nuclear DNA amounts of the terrestrial earthworms Octodrilus complanatus and Eisenia foetida (Annelida: Oligochaeta: Lumbricidae).
