Bird–plant seed‐dispersal networks are structural components of ecosystems. The role of bird species in seed‐dispersal networks (from less [peripheral] to more connected [central]), determines the interaction patterns and their ecosystem services. These roles may be driven by morphological and functional traits as well as evolutionary, geographical and environmental properties acting at different spatial extents. It is still unknown if such drivers are equally important in determining species centrality at different network levels, from individual local networks to the global meta‐network representing interactions across all local networks. Using 308 networks covering five continents and 11 biogeographical regions, we show that at the global meta‐network level species' range size was the most important driver of species centrality, with more central species having larger range sizes, which would facilitate the interaction with a higher number of plants and thus the maintenance of seed‐dispersal interactions. At the local network level, body mass was the only driver with a significant effect, implying that local factors related to resource availability are more important at this level of network organisation than those related to broad spatial factors such as range sizes. This could also be related to the mismatch between species‐level traits, which do not consider intraspecific variation, and the local networks that can depend on such variation. Taken together, our results show that the drivers determining species centrality are relative to the levels of network organisation, suggesting that prediction of species functional roles in seed‐dispersal interactions requires combined local and global approaches.

Bird-plant seed-dispersal networks are structural components of ecosystems and have been used to assess species’ functional roles. The role that bird species play in seed-dispersal networks (from less connected [peripheral] to more connected [central]), determine the interaction patterns and their ecosystem services. These roles may be determined by drivers related to morphological and functional traits, evolutionary properties, geography, and environmental conditions acting at different spatial and temporal scales. However, it is still unknown if such drivers are equally important in determining species centrality at different network levels, from individual local networks to the global meta-network representing interactions across all local networks. Here, using a dataset of 314 local networks covering five continents and eleven biogeographic regions, we show that drivers related to geography are more important in explaining species centrality in the meta-network, but these drivers were not as important in local networks. At the global meta-network level, we found that species’ range size was the most important driver with more central species having larger range sizes, which would facilitate the interaction with a higher number of plant species and thus the maintenance of seed-dispersal interaction patterns at the global scale. Morphological traits such as beak width, body mass, and wing length had secondary explanatory power. At the local network level, none of the tested drivers of centrality had significant effects, perhaps because local factors related to resource availability are more important at this scale. Taken together, our results show that the drivers determining species centrality are scale dependent, suggesting that prediction and protection of species functional roles in seed-dispersal interactions requires a combined local and global approach.

“…We used the scientometric methodology to review the scientific studies (Vanti, 2002). The adopted methodology is interdisciplinary (Van Raan, 1997) and efficient in several subareas of knowledge, as demonstrated in several studies (Collavizza et al, 2021;Zakka et al, 2021;Frota et al, 2020;De David et al, 2020;Spanholi et al, 2020;Teodoro et al 2020;Baldiviezo et al 2019;Morocco et al 2019). This type of approach makes it possible to understand how a given field of science is structured and organized (Ochoa et al, 2014) and can map any problems in science, as well as analyze and compare concepts and ideas in a given field (Ding et al, 2001).…”

This scientometric study aimed to outline an overview of studies on ecotourism in the Pantanal published between 1990 and 2020. In this sense, studies published in the form of books, book chapters and scientific articles in journals were selected. Data were collected using the Web of Science, Scopus and, Science Direct databases, as well as the Google Scholar tool. We identified 36 published works on the subject. In 2020, seven studies were published, this being the year with the largest number of publications. 84% (n = 30) of the works were published in scientific journals, 8% (n = 3) in the form of book chapters and 8% (n = 3) in the form of books. Altogether, 92 authors wrote on the subject, but only 13 of them published at least two works. The highlights were C.J.R. Alho, with 4 publications, followed by R. Hoogesteijn and F. R. Tortato, with 3 each. Among the journals, Ecological Economics was the only one to present 3 articles. The most discussed topics were Ecotourism, Conservation, Biodiversity and Pantanal. Similarly, in the works’ keyword network, the words Pantanal, Conservation, Biodiversity and Tourism stood out.Finally, it is suggested that research institutions and Brazilian tourism associations should increase their partnerships to strengthen the research process on ecotourism in the Pantanal.
