dc.description.abstract Carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) contents were measured in the most common caprellid species inhabiting intertidal ecosystems of southern Spain ( Caprella acan- thifera , C. danilevskii , C. dilatata , C. equilibra , C. grandimana , C. hirsuta , C. liparotensis and C. penantis ). Five gammarid species ( Ampithoe sp., Apherusa sp., Hyale perieri , H. schmidtii and Jassa marmorata ), 3 isopods ( Dynamene edwardsi , Idotea chelipes and Ischyromene lacazei) and the tanaid Tanais dulongii were also collected for comparisons. Univariate analyses showed that S con- tent was significantly higher in caprellids (mean ± SD; 1.5 ± 0.3%) than in gammarids (1.1 ± 0.1%), isopods (0.9 ± 0.2%) and tanaids (0.9 ± 0.3%), and N showed significantly higher concentrations in caprellids (6.0 ± 0.9%) and gammarids (6.2 ± 0.5%) than in isopods (5.2 ± 0.8%) and tanaids (5.4 ± 0.4%). The average of the C and H contents by dry weight was 27.2 ± 3.1 and 4.6 ± 0.4%, respec- tively, in caprellids, 28.2 ± 2.3 and 4.7 ± 0.3% in gammarids, 26.8 ± 3.0 and 4.2 ± 0.5% in isopods and 26.4 ± 2.0 and 4.2 ± 0.3% in tanaids. The first axis of the principal component analysis associated with the concentrations for the 17 peracaridan species accounted for 69.7% of the total variance and cor- related significantly with C, H and N, while the second axis accounted for 25.1% of the variance and correlated with S. Caprellid females showed higher concentrations of C, H, N and S than males, but analysis of variance only showed significant differences in the percentage of C and H. The higher C and H contents in females could reflect a larger accumulation of lipids in the body and could be related to reproduction and differences in feeding habitats between males and females. es
