2323. A single-beam photothermal interferometer for in situ measurements of aerosol light absorptionBradley Visser, Jannis Röhrbein, Peter Steigmeier, Luka Drinovec, Griša Močnik, Ernest Weingartner, 2020, original scientific article Abstract: We have developed a novel single-beam photothermal interferometer and present here its application for the measurement of aerosol light absorption. The use of only a single laser beam allows for a compact optical set-up and significantly easier alignment compared to standard dual-beam photothermal interferometers, making it ideal for field measurements. Due to a unique configuration of the reference interferometer arm, light absorption by aerosols can be determined directly – even in the presence of light-absorbing gases. The instrument can be calibrated directly with light-absorbing gases, such as NO2, and can be used to calibrate other light absorption instruments. The detection limits (1σ) for absorption for 10 and 60 s averaging times were determined to be 14.6 and 7.4 Mm−1, respectively, which for a mass absorption cross section of 10 m2 g−1 leads to equivalent black carbon concentration detection limits of 1460 and 740 ng m−3, respectively. The detection limit could be reduced further by improvements to the isolation of the instrument and the signal detection and processing schemes employed.

2330. The effect of exotic plants on taxonomic, phylogenetic and functional diversity of common reeds communitiesmaster'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.
