Climate change and tree growth in the Khakass-Minusinsk Depression (South Siberia) impacted by large water reservoirs

Abstract Regional and local climate change depends on continentality, orography, and human activities. In particular, local climate modification by water reservoirs can reach far from shore and downstream. Among the possible ecological consequences are shifts in plant performance. Tree-ring width of...
