Hydropower plants are important sources of renewable energy, but the climatic impacts of their constructions remain poorly explored. Considering that tree growth analysis is a useful tool to identify environmental impacts, this study aimed at using climate records and tree-ring chronologies to understand possible local climate changes caused by the construction of a hydropower plant in the 1980s in the State of Paran´a, Southern Brazil. Historical climatic data were obtained from the local meteorological station and surrounding municipalities and analyzed using ANOVA and means tests. The Pettitt test was additionally used to identify change-points in the meteorological data. Wood samples from a total of 60 trees from Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) and Cedrela fissilis Vell. (Meliaceae) were collected, and tree-ring chronologies were built using dendrochronological standard procedures. Chronologies for A. angustifolia and C. fissilis represented time periods from 1800 to 2016 and 1899?2015, respectively. Tree-ring growth responses to climatic variables were evaluated by adjusting generalized mixed linear models and the Spearman correlations. Our results evidenced that the hydropower plant altered the local climate, mostly influencing the hydrological cycle by increasing local rainfall, with monthly rain volumes being statistically higher than in other meteorological stations. Significant responses in the growth of A. angustifolia were found to be associated with the water level increase caused by the dam and of C. fissilis due to the increase in cloud cover.

This study presents a taxonomic review of the native species of Ericaceae in Rio Grande do Sul state, Southern Brazil, providing identification keys, synonymy, morphological descriptions, and specimen photograph plates, besides maps of geographic distributions and lists of studied specimens to assist in identification and conservation. We made literature reviews, collecting expeditions, and reviewed 14 Brazilian herbaria, plus an additional 17 online herbaria. We confirmed the occurrence of three genera, 10 species, and 11 taxa, including the new occurrence of Gaultheria ulei to the state. All species occur in the Brazilian subtropical highland grasslands of the Atlantic Rainforest. Five species were confirmed occurring in the temperate grasslands of the Pampas, where Agarista eucalyptoides and A. chlorantha were previously known and A. minensis, A. nummularia and Gaylussacia brasiliensis represent new records. Agarista eucalyptoides and Gaylussacia brasiliensis are the most widely distributed species in the state. Agarista nummularia and Gaylussacia brasiliensis are the only species registered in the coastal plains. Five species are threatened in the state flora: Agarista chlorantha (EN), A. minensis (VU), A. niederleinii (VU), Gaultheria itatiaiae (EN), and Gaylussacia pseudogaultheria (EN). Additionally, we highlight seed shape as a distinctive trait to separate species within Agarista. |
