    (Uva Wellassa University of Sri Lanka, 2021) Piyatissa, I.A.D.U.; Dias, P.C.B.; Bandara, T.; Mohotti, C.M.
    Mangroves are one of the important ecosystems found in many tropical and subtropical areas. The importance of mangrove ecosystems in Sri Lanka has highlighted in numerous scientific studies and the findings of these studies are disseminated through various publications indexed in popular scholar databases. Moreover, with the advancement of new technologies, knowledge of mangrove is also disseminated on popular social media platforms. Quantification of this information is important in determining the status of knowledge on mangrove and related science communication. In this backdrop, the present study focused on determining the status of knowledge on mangroves using the popular social media platform; Twitter™ and scholarly database; SCOPUS®. In social media analysis, 475 twitter messages/tweets related to the keyword „Mangrove‟ was extracted from the Twitter™ database. R programing language and various other packages (TwitteR, tm, word cloud etc.) were used in analyzing the textual data. Topic modelling was employed to identify the latent topics in mangrove related tweets. Scientometric analysis of mangrove related studies in Sri Lanka was carried out using the Scopus® database. Results of the Twitter™ analysis showed the existence of various subthemes in mangrove research (e.g. conservation and mangrove rehabilitation etc). Word cloud analysis has indicated that forests, restoration, blue carbon, coastal and communities were dominant keywords. Results of the scientometric analyses of Sri Lankan mangrove studies indicated an increment in mangrove related publications (p = 0.001, R2= 0.85). The relationship between annual Gross Domestic Production (GDP) and the number of publications was positive (p = 0.001, R2 = 0.83). In contrast to that, a few Sri Lankan authors and institutes/universities dominated in mangrove related publications (n=105). Keyword analysis of mangrove related publications indicated that studies on family Rhizophoraceae (n=38) were prevalent in the scientific literature. Findings of the present study indicated that expanding the mangrove related research to other institutions and facilitating research infrastructure is essential. Furthermore, scientific dissemination of these research findings in social media platforms is highly encouraged. Keywords: Twitter™; Scopus®; Mangroves; Data mining; Topic modelling; R Programming
