由B。Virginica在米拉和瓜迪亚纳河口。然而，颗粒有机物（POM）也贡献了B。virginica生物量，高达26和37%，米拉和瓜迪亚纳河口分别。POM池显然是由陆地来源的OM，基于稳定同位素比值和C：N POM。陆源有机质是河口水母的一种未描述的碳源。我们的研究结果支持了一个工作假设，即地面来源的OM可能支持良好的生理条件的B。virginica期间的低后生浮游动物丰度，通过碎屑为基础的微生物食物网转化。营养途径的后续研究应该评估的时间贡献的本地和外来的OM及其后果，占跨生态系统（陆地河口海洋）的连接和车厢内的相互作用（远洋底栖）。
by B. virginica in both Mira and Guadiana estuaries. However, particulate organic matter (POM) also contributed to B. virginica biomass, up to 26 and 37% in Mira and Guadiana estuaries, respectively. The POM pool was apparently comprised by terrestrial-derived OM, as based on stable isotope ratios and C:N POM . Terrestrial-derived OM is an undescribed carbon source for estuarine jelly fi sh. Our results support a working hypothesis stating that terrestrial-derived OM might support good physiological condition of B. virginica during periods of low metazooplankton abundance, through a detritus-based microbial food web transformation. Subsequent studies on trophic pathways ought to evaluate the temporal contribution of autochthonous and allochthonous OM and its consequences, accounting for the connectivity across ecosystems (terrestrial-estuarine-marine) and the interactions within compartments (pelagic-benthic).
