- Citizen science as a monitoring tool in aquatic ecology: trends, gaps, and future perspectivesPublication . Lameira, Helton Luis Nina; Guerrero-Moreno, Mayerly Alexandra; Silva, Everton Cruz da; Oliveira, Fernando Abreu; Teodosio, Maria; Dias-Silva, Karina; Moura, James Ferreira; Juen, Leandro; Oliveira-Junior, José Max BarbosaAquatic ecosystems are essential for biodiversity and ecosystem services, but anthropogenic pressures threaten them. In this context, citizen science has emerged as an innovative strategy for biodiversity conservation and environmental monitoring. We conducted a scientometric analysis to identify patterns and gaps in the scientific literature on citizen science in aquatic ecology. We analyzed 185 articles published between 2003 and 2024 on the Web of Science and Scopus databases, with the highest number of publications on the topic (15.14%) in 2023. The United States, Australia, and the United Kingdom were the most productive and frequently studied countries. Studies focused on marine ecosystems (50.28%), while freshwater environments, such as rivers (12.99%), remain under-represented. Taxonomic groups such as fish (30.64%) and aquatic mammals (13.87%) were most commonly studied. The focus of monitoring was on ecology and species conservation. The projects adopted a contributory model of citizen engagement (92.97%), with a predominance of urban citizens (60.51%). Participants were trained through online platforms (25.75%) and in-person courses (21.56%), while communication methods involved sharing photos and videos (38.77%) and online uploads (23.79%). Therefore, expanding studies on freshwater ecosystems and rural and traditional communities, and integrating different levels of citizen participation, is essential.
- Use of aquatic organisms as flagship species in selecting priority areas for conservationPublication . Guerrero-Moreno, Mayerly Alexandra; Silva, Everton Cruz da; Oliveira, Fernando Abreu; Nascimento, Ana Caroline Leal; Michelan, Thaisa Sala; Dias-Silva, Karina; Teodosio, Maria; Jr, James Ferreira Moura; Oliveira-Junior, José Max Barbosa; Juen, LeandroFlagship species are widely used to garner support for conservation, but the selection of these taxa often overlooks ecological, social, and cultural criteria, which may limit the effectiveness of conservation efforts in priority areas. Furthermore, this approach often fails to adequately reflect the importance of ecosystems. A notable example is the undervaluation of aquatic environments, which are frequently neglected or assessed using terrestrial groups whose characteristics and requirements do not necessarily align with the specific demands of these ecosystems. In light of this, we conducted a scientometric analysis to map the scientific literature on the use of aquatic organisms as flagship species for selecting priority conservation areas, highlighting global trends and gaps. A total of 400 articles published between 1997 and 2024 were analyzed from the Scopus and Web of Science databases. The highest number of articles published was in 2021 (n = 46; 11.5 %). Australia (n = 49) and Brazil (n = 34) were the countries most frequently studied. The most frequently researched areas were marine/ coastal protected areas (43.75 %) and unprotected natural areas (42.50 %). More than 80 % of the flagship species belonged to the phylum Chordata, with notable representation from Actinopterygii (bony fishes; 43.58 %) and Mammalia (20.18 %). The most commonly used taxon selection criteria were “conservation status” (57.17 %) and “charisma and emblematic value” (15.80 %). Despite the representation of marine ecosystems (58.63 %), freshwater habitats such as rivers (16.78 %), lakes (4.96 %), and streams (4.26 %) remain underrepresented. The most frequently employed research methods and response metrics were “abundance and density” (39.04 %) and “monitoring and observation” (38.32 %). We identified a significant bias favoring marine ecosystems and charismatic taxa, neglecting freshwater habitats and less visible but ecologically important groups. We emphasize the need to diversify conservation strategies by adopting more inclusive approaches that encompass the full range of aquatic biodiversity and habitats, particularly those that are underrepresented. Such diversification is essential for strengthening public policies and practices aimed at protecting critical ecosystems and ensuring global environmental sustainability.
