Overview of the History of Biological Oceanography in the Southwestern Atlantic, with Emphasis on Plankton

New species of Eirenidae (Hydrozoa: Leptothecata) from the Amazonian coast (northern Brazil)

“…was restricted to coastal waters under the influence of the Amazon River plume. Knowledge on the zooplankton community inhabiting waters of the Amazonian coast is still scarce (Boltovskoy and Valentin 2018). Recently, this unique ecosystem has attracted attention from scientific and public society because of the presence of hard-bottom reefs (Moura et al 2016) and oil exploitation in the area (Silva Junior and Magrini 2014), which may lead SCI.…”

Analysis of three decades of research in marine sciences in Uruguay through mapping of science and bibliometric indexes

“…However, after more than 20 years of constant growth, the publication number's development shows stagnation signs. In this sense, these results could be interpreted as that Uruguay's marine science is constrained by some factors such as the accessibility to expensive oceanographic equipment (Lauro et al 2014, Boltovskoy & Valentin 2018. However, the limited number of new permanent working positions in fields related to marine sciences, the "dispersion" of the research groups and areas, and the lack of a university degree in marine science or oceanography may also contribute to the observed stagnancy.…”

“…For that reason, the quantitative analysis of the publications of an academic community (bibliometric approach) is widely accepted to evaluate trends and patterns in most areas of scientific research (Moody & Light 2006, Edelman et al 2017, Borrett et al 2018. However, in Latin America, this type of analysis is scarce in natural sciences (but see Boltovskoy & Valentin 2018, Nielsen-Muñoz et al 2018 and, in particular, nonexistent in Uruguay for the case of marine science.…”

First record of Cirrholovenia polynema (Hydrozoa: Leptothecata) in the Western Atlantic Ocean

“…Yet, its presence in offshore areas slightly away from the shelf break and around oceanic islands is not unusual (Kramp 1965, Michel 1969, suggesting the species can potentially inhabit this environment (probably driven by currents) reaching new areas for polyp settlement, and it would justify its wide distribution in tropical and subtropical areas around the world. Knowledge regarding zooplankton biodiversity in general and cnidarians in particular from the waters off North and Northeast Brazil is scarce (Oliveira et al 2016, Boltovskoy andValentin 2018). Thus, the current report contributes not only to the understanding of local biodiversity, but also for and adequate comprehension of global biogeographic and diversity patterns.…”
