Understanding the blood-feeding patterns of mosquitoes is essential for evaluating their potential as disease vectors, especially in urban areas where mosquitoes coexist with humans, domestic animals and wildlife. This study aimed to bridge a substantial gap in regional knowledge by identifying the blood meal sources of field-collected mosquitoes in domestic and open green environments from two urbanisations of temperate Argentina, the Área Metropolitana de Buenos Aires (AMBA) and Tandil, using molecular techniques. Female mosquitoes were collected from November 2019 to March 2020 and April–May 2021. A bipartite network analysis was performed for each environment and urbanisation. A total of 103 blood meals from Aedes (2 species) and Culex (7 species) were identified. Among these, five mammal and 18 bird species were recognised as hosts. Aedes mosquitoes exclusively fed on mammals, while Culex mosquitoes exhibited a broader host range including both birds and mammals. In AMBA, the open green environments were composed by more mosquito species than the domestic environments, while both presented similar numbers of vertebrate species. In contrast, in open green environments from Tandil only blood-fed Aedes albifasciatus were collected. For open green environments of AMBA and domestic environments of Tandil, results suggested some degree of host selection. For the three main vectors of diseases in the region, Aedes aegypti, Ae. albifasciatus and Culex pipiens molestus, we present the first molecular evidence of human blood meals in South America. Epidemiological significance of the present findings is discussed.

Combining global perspectives with localized case studies and integrating scientific and material evidence of environmental change in historical narratives are amongst the main challenges for the field of global history in addressing the dawn of the Anthropocene. In this article, we trace the relationship of the city of Gerasa (Jerash, Jordan) with its riverine hinterland, from the first millennium BCE until the nineteenth century CE. We argue that the study of long-term historical trajectories of microregions not only depends on context from regional and global history timelines, but also has the potential to provide insights relevant to those scales in return. Zooming in and scaling up must go hand in hand in order for global history perspectives to be properly informed, and archaeology and natural sciences have crucial insights to offer – although importantly only when evidence comes from well-contextualized frameworks.

The aim of this article is to offer introductory theoretical arguments in order to research the role that urban ludic spaces play in post-migrants' everyday processes of situated learning. I discuss how situated learning processes are embedded in everyday webs of relationships, with special reference to spatial construction of intersectionality within power laden spaces affecting the way in which communities of practice develop in urban areas. I draw on results from a previous research carried out in diverse neighbourhoods of central and north-east Italian cities as an example of the way in which public playgrounds could be laden by power and could in this way affect the opportunities to share everyday practices and to build up a community of practices in non-formal and informal learning environments.
