GUERRERO, Elián Leandro  and  AGNOLIN, Federico Lisandro. Rev. Mus. Argent. Cienc. Nat. [online]. 2016, vol.18, n.1, pp.75-83. ISSN 1853-0400.

The Northern region of Buenos Aires province, in Argentina, suffered an uninterrupted increase in rainfall and temperature values during the last decades. The aim of the present contribution is to analyze the effects of such climatic change in the distribution of local flora and fauna. The analysis resulted in the recognition of distributional shifts in a total of 115 species. These changes represented the progressive southern expansion of species typically present in subtropical areas. Because all these changes have a similar orientation and direction, and included a large number of plant and animals with different ecological requirements, it is here postulated that those geographical changes are probably a response to climatic alteration.
