    Co-Authors: Morato Telmo, González-irusta José-manuel, Dominguez-carrió Carlos, Wei Chih-lin, Davies Andrew, Sweetman, Andrew K., Taranto, Gerald H., Beazley Lindsay, García-alegre Ana, Grehan Anthony
    Abstract:

    The deep sea plays a critical role in global climate regulation through uptake and storage of heat and carbon dioxide. However, this Regulating Service causes warming, acidification and deoxygenation of deep waters, leading to decreased food availability at the seafloor. These changes and their projections are likely to affect productivity, biodiversity and distributions of deep-sea fauna, thereby compromising key ecosystem Services. Understanding how climate change can lead to shifts in deep-sea species distributions is critically important in developing management measures. We used environmental niche modelling along with the best available species occurrence data and environmental parameters to model habitat suitability for key cold-water coral and commercially important deep-sea fish species under present-day (1951–2000) environmental conditions and to project changes under severe, high emissions future (2081–2100) climate projections (RCP8.5 scenario) for the North Atlantic Ocean. Our models projected a decrease of 28%–100% in suitable habitat for cold-water corals and a shift in suitable habitat for deep-sea fishes of 2.0°–9.9° towards higher latitudes. The largest reductions in suitable habitat were projected for the scleractinian coral Lophelia pertusa and the octocoral Paragorgia arborea, with declines of at least 79% and 99% respectively. We projected the expansion of suitable habitat by 2100 only for the fishes Helicolenus dactylopterus and Sebastes mentella (20%–30%), mostly through northern latitudinal range expansion. Our results projected limited climate refugia locations in the North Atlantic by 2100 for scleractinian corals (30%–42% of present-day suitable habitat), even smaller refugia locations for the octocorals Acanella arbuscula and Acanthogorgia armata (6%–14%), and almost no refugia for P. arborea. Our results emphasize the need to understand how anticipated climate change will affect the distribution of deep-sea species including commercially important fishes and foundation species, and highlight the importance of identifying and preserving climate refugia for a range of area-based planning and management tools.The deep sea plays a critical role in global climate regulation through uptake and storage of heat and carbon dioxide.

  • development and evaluation of a new index to assess hydrologic Regulating Service at sub watershed scale
    Ecological Indicators, 2018
    Co-Authors: Hua Zheng, Wenting Liao
    Abstract:

    Abstract Hydrologic regulation is an important ecosystem Service, and is easily influenced by human disturbance. Many studies have been conducted on the impacts that human activities have on flow regime and Regulating capacity by a single environmental factor. However, these studies have not clarified the comprehensive effects at sub-watershed scale; these effects are important for sub-watershed management. This research was conducted to reveal the spatial heterogeneity of hydrologic Regulating Service and identify the impact factors in China’s Yangtze River Basin. This basin is the largest in China and frequently floods. We built a new index based on the coefficients of variation for precipitation and runoff. The proposed indicator reflected the relative strength of Regulating Service effectively, and distinguished the basin into two different groups (A and B) of sub-watersheds. The hydrologic Regulating index was significantly and positively correlated to slope and coverage of bush and forest, and negatively correlated to hydraulic projects, farmland, and urban area. Land-use changes have the greatest contribution (more than 60%) to differences in sub-watershed hydrologic Regulating Service. Compared with the sub-watersheds of group A, the sub-watersheds of group B suffered more severe human activity, for which the relative contributions to hydrologic Regulating Service were 32.18% (hydraulic projects), 18.21% (farmland) and 6.21% (urban area). These results indicated that the ecological effects of human activities should be a concern, and that restoration of the natural environment should play an important role for hydrologic Regulating capacity enhancement. Group A sub-watersheds should explore the existing massive potential of (cascade) reservoirs for improving hydrologic Regulating ability. Our results not only present a useful tool for watershed hydrologic Regulating assessment, but lay a foundation for exploring differentiated management strategies of flood mitigation at sub-watershed scale.

  • Strengthening protected areas for biodiversity and ecosystem Services in China
    Proceedings of the National Academy of Sciences of the United States of America, 2017
    Co-Authors: Yi Xiao, Hua Zheng, Jingjing Zhang, Wu Yang, Lu Zhang, Vanessa Hull, Zhi Wang, Jianguo Liu, Stephen Polasky
    Abstract:

    Recent expansion of the scale of human activities poses severe threats to Earth's life-support systems. Increasingly, protected areas (PAs) are expected to serve dual goals: protect biodiversity and secure ecosystem Services. We report a nationwide assessment for China, quantifying the provision of threatened species habitat and four key Regulating Services-water retention, soil retention, sandstorm prevention, and carbon sequestration-in nature reserves (the primary category of PAs in China). We find that China's nature reserves serve moderately well for mammals and birds, but not for other major taxa, nor for these key Regulating ecosystem Services. China's nature reserves encompass 15.1% of the country's land surface. They capture 17.9% and 16.4% of the entire habitat area for threatened mammals and birds, but only 13.1% for plants, 10.0% for amphibians, and 8.5% for reptiles. Nature reserves encompass only 10.2-12.5% of the source areas for the four key Regulating Services. They are concentrated in western China, whereas much threatened species' habitat and Regulating Service source areas occur in eastern provinces. Our analysis illuminates a strategy for greatly strengthening PAs, through creating the first comprehensive national park system of China. This would encompass both nature reserves, in which human activities are highly restricted, and a new category of PAs for ecosystem Services, in which human activities not impacting key Services are permitted. This could close the gap in a politically feasible way. We also propose a new category of PAs globally, for sustaining the provision of ecosystems Services and achieving sustainable development goals.
