Soil enzyme activities are often used as indicators of soil contamination. The responses of the activities of specific soil enzymes, dehydrogenase, acid phosphatase, β-glucosidase, carboxylesterase, and urease to different land uses (soybean and rice crops, and a reference site) were analyzed. Changes in activity at the start and end of each crop c...

Introduction: Recognition of the variety of ecosystem services that biodiversity performs in agroecosystems is one of the basic principles of agroecology. Because indices of functional diversity may be directly related with ecosystem services, an assessment of functional diversity can be useful for evaluating ecosystem services provided under agroe...

The toxic or nutritionally deleterious effects resulting from the consumption of genetically modified (GM) foods are still a matter of debate worldwide. In amphibians, the environmental impact of the Bacillus thuringiensis (Bt) toxin (e.g., Cry proteins) engineered into GM Bt crops is barely known. Thus, the aim of the present study was to evaluate...
