Insects of the order Odonata have been used as indicators of environmental quality in different aquatic systems around the world. In this context, we conducted a bibliometric analysis to understand the general patterns of research on Odonata published in the past decade (2012-2021). We extracted literature from the Web of Science (WoS) in the advanced search option and used search terms related to Odonata plus search strings for each term. A total of 2764 Odonata publications were identified. The journals with the most published articles on Odonata were Zootaxa, International Journal of Odonatology and Odonatologica. The countries with the most Odonata publications were the USA, Brazil and China. Most studies were conducted on streams, ponds and rivers. Ecology, taxonomy and behavior were the main study topics. Of the total articles on Odonata, 982 involved Zygoptera and 946 Anisoptera. Another 756 studies were focused on both suborders. The increase in ecological and taxonomic studies of Odonata reflects the dynamic characteristics of this order, and its relatively well-defined systematics, especially in the case of adults. Despite the recent increase in the number of publications, there are still many gaps related to topics such as biogeography, parasitism, competition within and between species, evolutionary and phylogenetic relationships, as well as studies of the eggs (e.g., their development) and larval exuviae (e.g., their morphological features).

Uruguay has recently expanded its Exclusive Economic Zone (EEZ), having more aquatic sovereignty than terrestrial territories. In this country, various State institutions have carried out the study of marine science for several decades, but their academic development has not been analyzed. The formal evaluation of scientific research represents a crucial opportunity to define long-term policies requiring greater knowledge of the territory and its resources. In this context, this work carries out a systematic and quantitative review of Uruguay authors’ international publications over three decades. The productivity indicators trend is evaluated concerning context variables, predominant research topics are identified, and collaboration networks are characterized. We collected and analyzed data on marine science articles in which an author or co-author is affiliated to an institution in Uruguay from 1990 to 2018 using the Scopus database. It was found that scientific activity measured by a bibliographic analysis showed an increase in the number of articles, authors, and research topics but nowadays show signs of stagnation. Moreover, specific indicators show a great degree of centralism (institutional and authorial), low dynamism, and decreased international collaboration. The largest academic capacities are focused in specific biological disciplines, with little physics and almost nil in geology and chemistry. Decentralization and strengthening sectorial funding for marine science will boost Uruguay’s discipline for facing future challenges.

Landslide occurrence has become increasingly influenced by human activities. Accordingly, changing land use and land cover (LULC) is an important conditioning factor in landslide susceptibility models. We present a bibliometric analysis and review of how LULC was explored in the context of landslide susceptibility in 536 scientific articles from 2001 to 2020. The pattern of publications and citations reveals that most articles hardly focus on the relationship between LULC and landslides despite a growing interest in this topic. Most research outputs came from Asian countries (some of which are frequently affected by landslides), and mostly with prominent international collaboration. We recognised three major research themes regarding the characteristics of LULC data, different simulated scenarios of LULC changes, and the role of future scenarios for both LULC and landslide susceptibility. The most frequently studied LULC classes included roads, soils (in the broadest sense), and forests, often to approximate the negative impacts of expanding infrastructure, deforestation, or major land use changes involving agricultural practice. We highlight several articles concerned primarily with current practice and future scenarios of changing land use in the context of landslides. The relevance of LULC in landslide susceptibility analysis is growing slowly, though with much potential to be explored for future LULC scenario analysis and to close gaps in many study areas.
