BACKGROUND AND AIMS Lichens can be both nitrogen- (N) and phosphorous- (P) limited and thus may be susceptible to nutrient enrichment. Nutrient enrichment with N and P may have differing impacts on the lichen structure because of different physiological responses of fungal and algal partners to these nutrients. The hypothesis was tested that the differential responses of lichen symbionts to enh...
Despite the high relevance of communities dominated by lichens, mosses and cyanobacteria living on soil surface (biocrusts) for ecosystem functioning in drylands, no study to date has investigated decomposition biocrust-forming lichen litter situ. Thus, we do not know whether drivers its are similar those plant (for example, importance abiotic degradation through UV radiation), magnitude rates ...
In Brazil, the snail Biomphalaria glabrata is the most important vector of schistosomiasis due to its wide geographical distribution, high infection rate and efficient disease transmission. Among the methods of schistosomiasis control, the World Health Organization recommends the use of synthetic molluscicides, such as niclosamide. However, different substances of natural origin have been teste...
