Black Sea Jellyfish: Shocking Newcomers to Suisun Marsh

Jellyfish populations in the Mediterranean Sea

The Mediterranean Sea is home to numerous species of jellyfish, both native and invasive. Some of these jellyfish, which here include pelagic cnidarians, ctenophores and salps, have been monitored for centuries, while others are rarely sampled or studied. In addition, particular species of jellyfish are of high public interest due to impacts on tourism and other human activities, yet others may...

Invasion Age and Invader Removal Alter Species Cover and Composition at the Suisun Tidal Marsh, California, USA

Wetland ecosystems are vulnerable to plant species invasions, which can greatly alter species composition and ecosystem functioning. The response of these communities to restoration can vary following invader removal, but few studies have evaluated how recent and long-term invasions can affect the plant community’s restoration potential. Perennial pepperweed (Lepidium latifolium) has invaded th...

Mass deposition of jellyfish in the deep Arabian Sea

In December 2002, large numbers of dead jellyfish, Crambionella orsini, were observed on the seabed over a wide area of the Arabian Sea off the coast of Oman at depths between 300 m and 3,300 m. Moribund jellyfish were seen tumbling down the continental slope. Large aggregations of dead jellyfish were evident within canyons and on the continental rise. At the deepest stations, patches of rottin...

EHPnet: Black Sea Change

Background: Epstein-Barr virus has been proved to be associated with many of the human malignancy including gastric carcinoma, one of the most important human malignancies in the world. There has been no study about the presence of EBV in gastric adenocarcinoma in Iran. Methods: We examined the presence of EBV in 273 formalin fixed paraffin-embedded cases of gastric carcinoma from Cancer instit...
