Seasonal variation of the lipid content in Trigriopus californicus (Backer) (Copepoda, Harpacticoida)
Seasonal variations of the body weight, water content and lipid amount in adult individuals of Tigriopus californicus (Backer) from peninsula Foca, Puerto Deseado (Sta. Cruz) were studied. Correlations among them were found. Experiences were realized during 1978 and 1979, using 100 individuals as op...

Seasonal variations of the body weight, water content and lipid amount in adult individuals of Tigriopus californicus (Backer) from peninsula Foca, Puerto Deseado (Sta. Cruz) were studied.

Seasonal variations of the body weight, water content and lipid amount in adult individuals of Tigriopus californicus (Backer) from peninsula Foca, Puerto Deseado (Sta. Cruz) were studied. Correlations among them were found.
