Figure 2.
Variation of volume-specific pumping rates [PRV, ml min−1 (cm sponge)−3] throughout the years in the five study species. The temperature variation over the annual cycles at the study site is included in each species graph as empty dots. Data are expressed as mean ± SE. The maximal seasonal variation of PRV was 2.5 folds, depending on the species: A. oroides, 2.4; C. reniformis, 2.1; P. ficiformis, 2.5; D. avara, 1.9; C. crambe, 2.1.
