JELLYFISH BLOOMS Response of Chrysaora quinquecirrha medusae to low temperature
Because of their high abundance in Chesapeake Bay, Chrysaora quinquecirrha medusae may be an important reservoir of organic matter. The timing and location of the decomposition of biomass from medusae may have implications for carbon cycling in the bay. Our objective was to identify the cause of C. quinquecirrha medusa disappearance to better understand when and where decomposition occurs. A ti...
متن کاملIn vitro radical scavanging activities of Chrysaora quinquecirrha nematocyst venom.
The venom of Chrysaora quinquecirrha (sea nettle) contains several toxins that have bioactivity in mammals. In our study we aimed to extract proteins from Chrysaora quinquecirrha and to test the antioxidant potential of both crude protein and purified fractions. Proteins extracted from sea nettle nematocyst venom were purified through Sephadex G-100 column chromatography. The molecular weight o...
متن کاملMolecular evidence for cryptic species of Aurelia aurita (Cnidaria, Scyphozoa).
Morphological taxonomy suggests that marine faunas are species poor compared to terrestrial and freshwater faunas (1). This dichotomy has been attributed to the unique potential of marine plankters for distant dispersal across homogenous oceans with few barriers to gene flow (2). The relative scarcity of opportunities for allopatric divergence has resulted in depauperate marine faunas character...
متن کاملTentacle Transcriptome and Venom Proteome of the Pacific Sea Nettle, Chrysaora fuscescens (Cnidaria: Scyphozoa).
Jellyfish venoms are rich sources of toxins designed to capture prey or deter predators, but they can also elicit harmful effects in humans. In this study, an integrated transcriptomic and proteomic approach was used to identify putative toxins and their potential role in the venom of the scyphozoan jellyfish Chrysaora fuscescens. A de novo tentacle transcriptome, containing more than 23,000 co...
متن کاملLack of genetic structure in the jellyfish Pelagia noctiluca (Cnidaria: Scyphozoa: Semaeostomeae) across European seas.
The genetic structure of the holopelagic scyphozoan Pelagia noctiluca was inferred based on the study of 144 adult medusae. The areas of study were five geographic regions in two European seas (Eastern Atlantic and Mediterranean Sea). A 655-bp sequence of mitochondrial cytochrome c oxidase subunit I (COI), and a 645-bp sequence of two nuclear internal transcribed spacers (ITS1 and ITS2) were an...
