The effect of exotic plants on taxonomic, phylogenetic and functional diversity of common reeds communities
master's thesis

Abstract: Macrophytes have a pivotal role as point of interaction between many of the organisms, and the water and sediment chemistry in a freshwater system. Despite their low floristic diversity, reeds beds can support a wide range of wildlife, and provide a variety of functions for the wetland ecosystems. Recent studies show the existence of a threshold effect of alien plant cover or density on plant communities dominated by P. australis, whereby more increased the alien plant impact is, more reduced may be the native plant species diversity. However, many of these studies were based on taxonomical or traits information, whereas no investigations have considered the phylogenetic dimension so far. This study aims to investigate the incidence of alien species on the phylogenetic diversity of wetland vegetation dominated by P. australis. To do this, we investigated the floristic composition of a total of 98 natural reeds beds from Tuscany, Umbria, and Lazio, analysing separately lentic and lotic communities. We constructed a phylogenetic tree of the plant species and compared the differences in taxonomic/functional/phylogenetic diversity, evaluating the role of the incidence of the alien species. The results showed that the relative abundance of exotic plant species is positively related to the taxonomic diversity of the common reeds communities and doesn’t affect the phylogenetic diversity. Probably, the human impact promoted the entrance of the exotic species already represented at evolutionary level. Also, the presence of exotic species influenced functional diversity, especially it promoted the adaptive strategies ruderals of the communities.

Antimicrobial susceptibility profile of airborne bacteria and fungi at Owena Market, Osun State, Nigeria
Gbenga Folorunsho Oginni, Sandra Oloketuyi, Olufunke Chukwu, Janet Odunayo, 2017, original scientific article

Abstract: Environmental conditions and human activities influence the ubiquity and diversity of microorganisms in the atmosphere thereby acquiring the ability to resist antibiotics which poses serious public threat. Airborne bacteria and fungi isolated using settling plate method from three different points (where kolanuts, meat and onions are sold) at Owena Market, Osun state, Nigeria were assayed for antimicrobial susceptibility using disc diffusion. The microorganisms were identified as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Proteus vulgaris, Bacillus megaterium, Alcaligenes spp., Aeromonas spp., Escherichia coli, Micrococcus spp., Streptococcus spp., Mortierella polycephala, Epicoccum nigrum, Alternaria spp., Penicillium chrysogenum, Aspergillus flavus, Acremonium spp., Penicillium oxalicum, Cladosporium cladosporiodes, Rhizopus stolonifer, Stemphylium spp., and Trichoderma spp. About 30% of the bacterial isolates were resistant to the antibacterial agents (antibiotics) and all the bacterial isolates were resistant to at least four or more antibiotics while 18% and 64% of the fungi isolated were susceptible to griseofulvin and ketoconazole, respectively. This study shows that the market environment serves as reservoirs for multiple antibiotic resistant bacteria and fungi capable of causing infectious diseases.
