The City

Urbanization has a negative impact on raptor species diversity and abundance. However, some species can adapt to urban areas, and the process of city colonization by raptors has been documented scarcely in the Northern Hemisphere. Information about city colonization by raptors in the Southern Hemisphere is null, and studies about habitat use by raptors are scarce. The objectives of this study were: (1) to describe an event of Harris Hawk (Parabuteo unicinctus) arrival in Mar del Plata city, Argentina, and (2) to analyze its green area use in a recently colonized city, Buenos Aires. Long-term data collected during 2002–2019, along an urbanization gradient of Mar del Plata, was used to describe the city arrival by the Harris Hawk. Surveys of green areas in Buenos Aires were used to model the Harris Hawk occurrence in relation to green area size and isolation to other green spaces. The Harris Hawk arrival was observed during 2019, mainly in periurban areas of Mar del Plata, and at least three pairs were breeding. In Buenos Aires, the occurrence of the Harris Hawk in green areas was related to the proximity to other large green areas. The results obtained suggest the importance of green areas for raptor colonization in cities.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

The paper considers monitoring of environmental change as the central element of environmental regulation. Monitoring, as each kind of principalagent relations, easily gives rise to corruptive behavior. In the paper we analyze economic models of environmental monitoring with high costs, incomplete information and corruption. These models should be the elements of environmental economics and are needed to create an effective system of nature protection measures.

History Of

This paper interrogates the history of same-sex dancing among women in Buenos Aires' tango scene, focusing on its increasing visibility since 2005. Two overlapping communities of women are invoked. Queer tangueras are queer-identified female tango dancers and their allies who dance tango in a way that attempts to de-link tango's two roles from gender. Rebellious wallflowers are women who practice, teach, perform, and dance with other women in predominantly straight environments. It is argued that the growing acceptance of same-sex dancing in Argentina is due to the confluence of four developments: 1) the rise of tango commerce, 2) innovations of tango nuevo, 3) changing laws and social norms around lesbian, gay, bisexual, and transgender rights, and 4) synergy between queer tango dancers and heterosexual women who are frustrated by the limits of tango's gender matrix. The author advocates for increased alliances between rebellious wallflowers and queer tangueras, who are often segregated from each other in Buenos Aires' commercial tango industry.
