“…Considering that macrophyte banks exhibit high diversity of periphytic algae (Pompêo and Moschini-Carlos 2003; Thomaz and Esteves 2011), the dispersal of these organisms may be favored by their adhesion to biological vectors. According to Adame et al (2021), the biological characteristics related to the adhesion strategy of periphytic algae determine the dispersal ability of the species. Souffreau et al (2013) reported that the genus Hantzschia sp is tolerant to desiccation, which may bene t its dispersal.…”

Although animal vectors facilitate algal dispersal, the speci c role of individual vectors in the temporal dynamics of algal community establishment remains unclear. In this study, we investigated the effects of wind and animal vectors, speci cally amphibians and odonates, on temporal variation in algal composition and abundance. We conducted a 33-day eld experiment in 2018 with four treatments that included different propagule additives. We identi ed 74 algal species from 11 taxonomic groups, with Chlorophyceae being the most abundant. Species richness and density varied signi cantly after day 12.Similarity in species composition and density increased over time in all treatments, with more species added at the beginning of the experiment and more species lost at the end. Our results suggest that different vectors had different effects on the local beta-temporal diversity of algal communities. The in uence of morphological differences among vectors and the number of dispersal vectors on the variation of beta diversity and community characteristics was observed. We found that dissimilarity changed more rapidly when there were multiple vectors capable of dispersing more individuals and species. The effectiveness of algal dispersal by different animal vectors and its in uence on the temporal dynamics of algal communities can vary in different environments and over longer periods of time. Overall, our study highlights the importance of understanding dispersal control and its relationship to the temporal dynamics of algal communities
