Uncoupling human and climate drivers of late Holocene vegetation change in southern Brazil
In the highlands of southern Brazil an anthropogenitcally driven expansion of forest occurred at the
expense of grasslands between 1410 and 900cal BP, coincident with a period of demographic and
cultural change in the region. Previous studies have debated the relative contributions of increasing
wetter and warmer climate conditions and human landscape modifcations to forest expansion, but
generally lacked high resoltiuon proxies to measure these efects, or have relied on single proxies to
reconstruct both climate and vegetation. Here, we develop and test a model of natural ecosystem
distribution against vegetation histories, paleoclimate proxies, and the archaeological record to
distinguish human from temperature and precipitation impacts on the distribution and expansion of
Araucaria forests during the late Holocene. Carbon isotopes from soil profles confrm that in spite of
climatic fuctuations, vegetation was stable and forests were spatially limited to south-facing slopes
in the absence of human inputs. In contrast, forest management strategies for the past 1400 years
expanded this economically important forest beyond its natural geographic boundaries in areas of
dense pre-Columbian occupation, suggesting that landscape modifcations were linked to demographic
changes, the efects of which are still visible today

Perfil da mortalidade materna por aborto no Paraná: 2003-2005 Perfil de la mortalidad materna, por aborto en el Paraná: 2003-2005 Characteristics of maternal mortality by abortion in Parana: 2003-2005
Estudo descritivo cujo objetivo foi identificar o perfil das mulheres que tiveram como causa de morte o aborto, no Estado do Paraná, no período entre 2003 e 2005, com destaque para aspectos sociodemográficos, reprodutivos e relacionados à assistência prestada. Os dados foram obtidos a partir dos estudos de série de casos de óbitos maternos elaborados pelo Comitê Estadual de Prevenção da Mortalidade Materna/Paraná. Foram analisados 17 casos. Os resultados apontaram que 88% dos óbitos poderiam ter sido evitados. O aborto seguido de infecção (59%) foi a causa básica de maior concentração entre as mortes. As mulheres jovens, casadas, com baixo status socioeconômico e reprodutivo foram as mais atingidas. Reafirma-se a importância do acesso a bens sociais, da redução das desigualdades sociais e da educação em saúde voltada para o planejamento reprodutivo de qualidade.<br>Estudio descriptivo cuyo objetivo fue identificar las características de las mujeres que tuvieron como causa de muerte el aborto en el estado de Paraná en el período entre 2003 a 2005, con destaque para aspectos sociodemográficos, reproductivos y al cuidado que recibieron.

The data was obtained from case series of maternal mortality by the State Committee of Maternal Death Prevention/Parana. There were seventeen cases analyzed and the figures showed 88% of them could have been avoided. The abortion cases followed by infection (59%) were the basic cause of the major concentration of avoidable mortalities. Young married women with a low socio-economic status and fertility were the most affected. This way, it reaffirms the importance of access to social welfare and to health education towards a qualified reproductive planning
