Understanding negative effects of native species on introduced taxa may suggest novel ways to control the invasive species by enhancing such effects. Previous studies have reported that the larvae of invasive cane toads (Rhinella marina) are suppressed by competition with the larvae of native anurans in Australia, but not in North America. We conducted laboratory trials to measure the effect of...

Millet, milo, soybean, crotalaria, and Norman pigeon pea were used in conjunction with clean fallow and a nematicide (fensulfothion) for managing nematode populations in the production of tomato transplants (Lycopersicon esculentum Mill.). Glean fallow was the most effective treatment in suppressing nematode numbers. After 2 years in tomato, root-knot nematodes increased in numbers to damaging ...

Dehaloperoxidase (DHP) from Amphitrite ornata is the only heme-containing, hydrogen peroxide-dependent globin capable of oxidatively dehalogenating halophenols to yield the corresponding quinones. To ascertain that this enzymatic activity is intrinsic to DHP, we have cloned and expressed the enzyme in Escherichia coli. We also find that an alternate oxygen atom donor, meta-chloroperbenzoic acid...

Generally, heavy metals enter into the aquatic environment through atmospheric deposition, erosion of geological matrix or due to anthropogenic activities caused by industrial effluents, domestic sewage and mining wastes. The present study analyzed the concentration of seven elements (Cd, Cu, Mn, Ni, Pb, Zi and Hg) in eight seaweeds such as Centrocerous clavutum, Sargassum wightii, Colpemenia s...
