The global transfer of live bait creates a potent vector (mechanism) for invasion of marine species, including associated biota (“hitchhikers”) not intended for shipment. Unlike other vectors of non-native species transfer in coastal marine systems (e.g., ship ballast water), vector management strategies to reduce transport of associated biota with live bait are lacking. In this study, we exper...

Transitions from marine to freshwater habitats constitute dramatic shifts between 'adaptive zones' that have initiated the radiation and speciation of many taxa. As recently as 10?000 years ago, deglaciation resulted in marine fauna being trapped in freshwater lakes. In modern times, human activity has caused the acceleration of freshwater invasions from marine or brackish habitats, leading to ...

Infections associated with marine activities, particularly work or recreation in salt water, present unique diagnostic challenges for the infectious disease practitioner. Those caused by halophilic, non-cholera Vibrio species are increasingly being recognized in clinical practice. They typically follow saltwater injuries, especially those associated with coral. Because these infections can be b...

Water from swimming pools in the Miami area was analyzed for nitrates, chlorates and trihalomethanes. The average concentrations of nitrate and chlorate found in freshwater pools were 8.6 mg/liter and 16 mg/liter respectively, with the highest concentrations being 54.9 mg/liter and 124 mg/liter, respectively. The average concentration of total trihalomethanes found in freshwater pools was 125 m...

Human anisakiasis is acquired through eating raw or undercooked saltwater fish or squid. Infestation with living larvae caused by eating parasitized fish often times results in gastroenteritis. It mainly involves the stomach and small intestine with no reported cases of eosinophilic esophagitis caused by Anisakidea. A 41-year-old man presented for the evaluation of 1 year of dysphagia to solid ...

Like the sailors in Samuel Coleridge's poem "The Rime of the Ancient Mariner" who see "water, water everywhere, nor any drop to drink," teachers often feel awash in a resource that is of little help. Teachers have more assessment data about individual students at their fingertips than we could have imagined a decade ago. Unlike saltwater to a thirsty mariner, the data are of course highly usabl...

Approximately 199 cladoceran species, 5 marine and 194 freshwater and continental saltwater species, live in China. Of these, 89 species are discussed in this paper. They belong to the 4 cladoceran orders, 10 families and 23 genera. There are 2 species in Leptodoridae; 6 species in 4 genera and 3 families in order Onychopoda; 18 species in 7 genera and 2 families in order Ctenopoda; and 63 spec...
