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.

Morpho-physiological aspects of the fat body of the haemolymph of the predator Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) males fed on Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae without plant; T. molitor pupae plus Eucalyptus cloeziana plants; T. molitor pupae plus Eucalyptus urophylla plants; T. molitor pupae plus guava plants (Psidium guajava) were analyzed. Haemolymph protein content and fat body morphology were analyzed in samples of B. tabidus males 15 and 21 days old. The haemolymph protein content of B. tabidus males was not affected by the diet or age of this predator. Adult of B. tabidus males had thophocytes with similar morphological aspects in all diets and ages analyzed, but they were twice bigger in those predator fed on T. molitor and plants of E. urophylla than with the other diets. The histochemical tests, proteins and carbohydrates showed weak reaction of the fat body of B. tabidus males with all diets and ages. These results are discussed in relation to the effect of plant supplementation in predator diets. |
