“…These microorganisms, which are known for their sensitivity to environmental fluctuations, serve as valuable paleoenvironmental indicators and provide profound insights into ancient aquatic ecosystems by uniquely responding to specific ecological conditions through changes in their abundance, presence or absence, and morphology (BATTARBEE et al 2002, SMOL 2022. Consequently, they have made significant contributions to the elucidation of critical past environmental changes including climate oscillations (FONTANA et al 2019, RODRÍGUEZ-ZORRO et al 2022, ALMARAZ-RUIZ et al 2023, BALASUBRAMANIAM et al 2023, SAROS et al 2023, limnological/ecological changes (WENGRAT et al 2019, hydrological regimes (RIBEIRO et al 2010, FAYÓ et al 2018, HAN et al 2023, alterations in land-use practices (TRÁBERT et al 2020, GARDOKI et al 2023, and the historical deposition of pollutants and eutrophication (BENNION et al 2004, COSTA-BÖDDEKER et al 2012, FONTANA et al 2014, SIMMATIS et al 2022, CHEN et al 2022, GREGERSEN et al 2023.…”

The use of diatoms in paleoenvironmental research is of the utmost importance for reconstructing past ecosystems because it provides crucial insights into the adaptability and resilience of these systems under ongoing climate change and increased human impacts. Maintaining a comprehensive dataset distribution is crucial to ensure the validity and relevance of these reconstructions on a global scale. This scientometric study aimed to analyze trends in diatom-based paleoenvironmental research on a global scale with an emphasis on South America. This study aimed to investigate disparities in the geographical distribution of diatom-based paleoenvironmental studies, collaboration networks in the field, and regions in which this research is lacking. The Scopus search criteria excluded certain types of publications, such as conference articles and notes. The search focused on articles, reviews, books and chapters of books using specific keywords aligned with the objectives of this study. Using the Scopus database, we identified 7,091 publications (1979-2023) that employed diatoms as a primary proxy for paleoenvironmental reconstruction. The results show significant changes in this field recent decades. The analysis highlights a marked upsurge in publication output during the 1980s and a substantial increase in publications after 2000. This upward trend in scientific documentation reflects the growing interest in and recognition of the importance of this field in the context of palaeoecology and environmental sciences. After 2011, the results revealed a shift in thematic focus from historical and geological reconstruction to ecological, anthropogenic, and climatic interactions. Key researchers, including Smol JP, Leng MJ, and Birks HJB, have been at the forefront of international collaborations. Since the 2000s, South American studies have focused primarily on lakes, climate change effects, and volcanic activity. In this region, researchers such as Maidana N.I., Urrutia, R., and García-Rodriguez, F. emphasized the significance of regional ecosystems and their paleoenvironmental history in the global context of the field. Despite its high biodiversity, South America contributed only 6.7% of the global research output, placing it 19th globally. Socioeconomic factors and other obstacles faced by researchers in the region could explain the observed disparity in scientific output in South America compared to other regions. To unlock South America’s vast potential for diatom-based paleoenvironmental research, which boasts the highest global biodiversity yet remains underrepresented in the field, stakeholders must implement equitable partnerships, increase funding and improve their academic infrastructure and opportunities. These strategies are crucial for advancing the global paleoenvironmental understanding, informing future conservation and environmental policies in South America, and promoting scientific progress on a global scale.

The effects of different concentrations (100,150,200,250 mg/L) and different particle sizes (0-75µm, 75-120µm, 120-150µm, 150-500µm) on soluble protein content, SOD and CAT activity, MDA content, chlorophyll a content and photosynthetic parameters of Microcystis os-aquae were studied, the mechanism of the effect of suspended particulate matter on the physiology and biochemistry of Microcystis os-aquae was discussed. The results showed that the soluble protein content of Microcystis os-aquae did not change obviously after being stressed by suspended particles of different concentration/diameter. The SOD activity of Microcystis os-aquae increased at rst and then decreased with the increase of the concentration of suspended particulate matter. The SOD activity of Microcystis os-aquae reached 28.03 U/mL when the concentration of suspended particulate matter was 100 mg/L. The CAT activity of Microcystis os-aquae increased with the increase of the concentration of suspended particles, and reached the maximum value of 12.45 U/mgprot in the concentration group of 250 mg/L, showing a certain dose-effect. The effect of small particle size on SOD, CAT and MDA of Microcystis osaquae was more signi cant than that of large particle size. The larger the concentration and the smaller the particle size, the stronger the attenuation of light and the lower the content of chlorophyll a. Both Fv/Fm and Fv/F 0 of Microcystis os-aquae increased at rst and then decreased under different concentration/size of suspended particles. The relative electron transfer rate gradually returned to the normal level with the passage of time. There was no signi cant difference in α value between treatment group and control group, ETRmax and I k decreased.
