The effectiveness of p-aminobenzoic acid (PABA) in overcoming sulfanilamide (SA) growth inhibition of Escherichia coli was explained on the basis that PABA was an essential metabolite and that SA interfered with -its utilization by the cell (Woods, 1940). Reversal of sulfonamide action by structurally unrelated metabolites such as methionine, xanthine, serine, thymine and valine (Shive, 1950; W...
The present study provides data to decide on the most appropriate method for sampling of ground-dwelling arthropods measured in a moist-deciduous forest in the Western Ghats in South India. The abundance of ground-dwelling arthropods was compared among large numbers of samples obtained using pitfall trapping, Berlese and Winkler extraction methods. Highest abundance and frequency of most of the...
Few studies have evaluated the efficiency of methods for sampling ants, especially in regions with highly variable vegetation physiognomies such as the Cerrado region of central Brazil. Here we compared three methods to collect ground-dwelling ants: pitfall traps, sardine baits, and the Winkler litter extractor. Our aim was to determine which method would be most appropriate to characterize the...
