15 صفحه اولDo leaf-litter attributes affect the richness of leaf-litter ants?
The search for factors shaping leaf-litter ant communities has received particular attention due to the essential role of these insects in many ecological processes. Here, we aimed to investigate how the number of leaves and leaf morphotypes affect the litter-ant species density at forest edge and interior in an Atlantic Forest remnant in the state of Alagoas, Brazil. This study was developed b...
متن کاملToxicity evaluation of diazinon contaminated leaf litter.
Diazinon (O,O-diethyl O-[2-isopropyl-6-methyl-4pyrimidinyl] phosphothiate) is an organophosphate pesticide with widespread use on a variety of agricultural crops, such as fruit trees, corn, and tobacco (Burkepile et al., 2000). Approximately 6 million kg of diazinon are applied annually in the United States and, as a result, are a potential contributer to nonpoint source contamination of aquati...

متن کاملGrowth and production of aquatic hyphomycetes in decomposing leaf litter
The acetate-to-ergosterol technique was used to estimate fungal productivity of three species of aquatic hyphomycetes growing in decomposing ash leaves in stream microcosms. Following a lag of 20-88 min, incorporation of acetate into ergosterol was linear for at least 10 h. Substrate saturation was reached in the mM range, and there was no indication of isotope dilution. For one species, Articu...
