Wind farm and solar park effects on plant–soil carbon cycling: uncertain impacts of changes in ground-level microclimate
Author: Armstrong, Alona; Waldron, Susan; Whitaker, Jeanette; and Ostle, Nicholas
Abstract – Global energy demand is increasing as greenhouse gas driven climate change progresses, making renewable energy sources critical to future sustainable power provision. Land-based wind and solar electricity generation technologies are rapidly expanding, yet our understanding of their operational effects on biological carbon cycling in hosting ecosystems is limited. Wind turbines and photovoltaic panels can significantly change local ground-level climate by a magnitude that could affect the fundamental plant–soil processes that govern carbon dynamics. We believe that understanding the possible . . .More »

Abstract – In Eastern Europe, wind energy production is currently promoted as an important source of renewable energy, yet in most cases without appropriate consideration of the negative impacts wind turbines (WT) may have on protected species such as bats. Here, we present first data on fatality rates, fatality factors and the likely origin of bats killed by WT in the Dobrogea region (Romania), located in a major migratory corridor for wildlife in Eastern Europe. Over a 4-year period, we found . . .More »

Abstract – Wind energy development is rapidly increasing within breeding and wintering ranges of many grassland birds in North America. Despite recognized environmental benefits of such development, wind farms have the potential to negatively impact bird communities. Using an area-search method, we surveyed grassland birds within a matrix of pastures, hay fields, and agricultural lands at a wind facility in north-central Texas during the winters of 2009/10 and 2010/11. We used binary logistic regression to examine the effect of distance from . . .More »

Abstract – We reviewed published and unpublished written reports on bat mortality at wind farms in northwestern Europe. The estimated number of bats killed per turbine annually was relatively low (0–3) on flat, open farmland away from the coast, higher (2–5) in more complex agricultural landscapes, and highest (5–20) at the coast and on forested hills and ridges. The species killed almost exclusively (98%) belonged to a group (Nyctalus, Pipistrellus, Vespertilio and Eptesicus spp.) adapted for open-air foraging. The bats were . . .More »
