One of the purposes of cooperation in the refugee regime is to enhance protection by helping refugees find a durable solution outside States of first asylum. In this cooperation option, the challenge is to encourage States of resettlement to voluntarily accept refugees. This article aims to question the "Solidarity Resettlement Programme" developed by Latin American States as a strategy to foster cooperation. To do so, it adopts two approaches. First, it gives a general account of how cooperation works in the refugee regime and eliminates the theoretical and empirical isolationism presented in the literature that praises the programme. Secondly, it explores the Latin American cooperation framework by applying E.H. Carr's analysis of utopia and reality. The findings indicate that regional cooperation in Latin America to enhance the protection of refugees continues to have more utopian elements than realist ones. [ABSTRACT FROM AUTHOR]

The bacterioplankton diversity of coastal waters along a latitudinal gradient between Puerto Rico and Argentina was analyzed using a total of 134,197 high-quality sequences from the V6 hypervariable region of the small-subunit ribosomal RNA gene (16S rRNA) (mean length of 60 nt). Most of the OTUs were identified into Proteobacteria, Bacteriodetes, Cyanobacteria, and Actinobacteria, corresponding to approx. 80% of the total number of sequences. The number of OTUs corresponding to species varied between 937 and 1946 in the seven locations. Proteobacteria appeared at high frequency in the seven locations. An enrichment of Cyanobacteria was observed in Puerto Rico, whereas an enrichment of Bacteroidetes was detected in the Argentinian shelf and Uruguayan coastal lagoons. The highest number of sequences of Actinobacteria and Acidobacteria were obtained in the Amazon estuary mouth. The rarefaction curves and Good coverage estimator for species diversity suggested a significant coverage, with values ranging between 92 and 97% for Good coverage. Conserved taxa corresponded to aprox. 52% of all sequences. This study suggests that human-contaminated environments may influence bacterioplankton diversity. [ABSTRACT FROM AUTHOR]
