Amphibians (tadpoles of the frog Bombina bombina [L.] and the newt Triturus vulgaris [L.]) and aquatic insects (larvae of the alderfly Sialis lutaria [L.] [Megaloptera], dragonflies Sympetrum sanguineum [Miller] and Coenagrion puella [L.] [Odonata], and the caddisfly Oligotrichia striati [L.] [Trichoptera]) were found to serve as paratenic hosts for the third-stage larvae (L3) of the nematode A...

In order to identify wild fruits possessing high nutraceutical potential, the antioxidant activities of 56 wild fruits from South China were systematically evaluated. The fat-soluble components were extracted with tetrahydrofuran, and the water-soluble ones were extracted with a 50:3.7:46.3 (v/v) methanol-acetic acid-water mixture. The antioxidant capacities of the extracts were evaluated using...

Influenza infection was induced in white mice by intranasal inoculation of the virus A/Aichi/2/68 (H3N2). The lung protease and the protease-inhibitory activities were followed for 9 days after infection. The intranasal application of a polyphenol-rich extract (PC) isolated from Geranium sanguineum L. induced a continuous rise in the anti-protease activity but did not cause substantial changes ...

Despite mass movements of insects being documented for decades, whether dragonflies migrate in Europe has not yet been experimentally tested. Similarly, little is known about the influence weather on movement decisions and intensity dragonflies. Taking advantage large along Baltic Sea coast Latvia, we investigated European showed directed indicative migratory behaviour how influences their move...

With the purpose to make a review on the red tides occurence at mexican coasts, previous studies were analyzed. Dinoflagellates seem to be the main cause of toxic events mainly Gonyaulax polygramma, Gymnodinium catenatum, Pyrodinium bahamense var. compressum and Ptychodiscus brevis. There are other species which cause red tides but are not toxic. They are: Mesodinium rubrum, Gonyaulax triacanth...

Survival, growth and pathology of juvenile oysters, Crassostrea virginica, in off-bottom culture at Oyster Bay and Fishers Island, New York, were monitored during the summer of 1991 to document and help explain the episodic mass mortalities of cultured seed oysters that have occurred in the northeastern USA over the past several years. At Oyster Bay, where the more detailed study was conducted,...
