Present proposed remedial measures based on engineering and technological fix are not likely to restore the ecological processes of a healthy, robust estuary and, as such, will not reinstate the full beneficial functions of the estuary ecosystem. The successful management of estuaries and coastal waters requires an ecohydrology- based, basin-wide approach. This necessitates changing present practices by official institutions based on municipalities or counties as an administrative unit, or the narrowly focused approaches of managers of specific activities (e.g., farming and fisheries, water resources, urban and economic developments, wetlands management and nature conservationists).

    Groundwater Microbial Communities in Times of Climate Change Alice Retter, Clemens Karwautz and Christian Griebler* University of Vienna, Department of Functional & Evolutionary Ecology, Althanstrasse 14, 1090 Vienna, Austria; * corresponding author Email: [email protected], [email protected], [email protected] DOI: https://doi.org/10.21775/cimb.041.509 Abstract Climate change has a massive impact on the global water cycle. Subsurface ecosystems, the earth largest reservoir of liquid freshwater, currently experience a significant increase in temperature and serious consequences from extreme hydrological events. Extended droughts as well as heavy rains and floods have measurable impacts on groundwater quality and availability. In addition, the growing water demand puts increasing pressure on the already vulnerable groundwater ecosystems. Global change induces undesired dynamics in the typically nutrient and energy poor aquifers that are home to a diverse and specialized microbiome and fauna. Current and future changes in subsurface environmental conditions, without doubt, alter the composition of communities, as well as important ecosystem functions, for instance the cycling of elements such as carbon and nitrogen. A key role is played by the microbes. Understanding the interplay of biotic and abiotic drivers in subterranean ecosystems is required to anticipate future effects of climate change on groundwater resources and habitats. This review summarizes potential threats to groundwater ecosystems with emphasis on climate change and the microbial world down below our feet in the water saturated subsurface. Introduction Groundwater ecosystems contain 97 % of the non-frozen freshwater resources and as such provide an important water supply for irrigation of agricultural land, industrial caister.com/cimb 509 Curr.

Abstract More than half of wetland area in the U.S. have been converted to other land use types for agricultural use and development. Limited understanding of ecological services provided to society by wetlands is another reason for the massive wetland loss in the past. Section 404 of the Clean Water Act and the 1989 federal mandate of “no net wetland loss” supported increased efforts for wetland restoration and creation to compensate for two centuries of ecosystem degradation. Hydrology is a critical driver for wetland formation and sustainability, yet few studies have investigated the ecosystem benefits of restored or constructed wetlands relative to natural wetlands. Considering that unexpected ecohydrologic behaviors such as drought have been reported as a main cause of unsuccessful restoration over the U.S., understanding and quantifying water movement within the local seeing is imperative to future wetland restoration. From an environmental engineering perspective, wetlands are regarded as complex environments controlled by regional geomorphology, atmosphere, geologic setting, and human activity.

Their spread in the environment can affect both plant and animal health. Ecohydrology serves as a solution for assessment approaches (i.e., threat identification, ecotoxicological assessment, and cause–effect relationship analysis) and solution approaches (i.e., the elaboration of nature-based solutions: NBSs), mitigating the toxic effect of CECs. However, the wide array of potential molecular analyses are not fully exploited in ecohydrological research. Although the number of publications considering the application of molecular tools in freshwater studies has been steadily growing, no paper has reviewed the most prominent studies on the potential use of molecular technologies in ecohydrology. Therefore, the present article examines the role of molecular methods and novel omics technologies as essential tools in the ecohydrological approach to CECs management in freshwater ecosystems. It considers DNA, RNA and protein-level analyses intended to provide an overall view on the response of organisms to stress factors. This is compliant with the principles of ecohydrology, which emphasize the importance of multiple indicator measurements and correlation analysis in order to determine the effects of contaminants, their interaction with other environmental factors and their removal using NBS in freshwater ecosystems.

    Journal of Sedimentary Research An International Journal of SEPM Paul McCarthy and Eugene Rankey, Editors A.J. (Tom) van Loon, Associate Editor for Book Reviews Review accepted 15 April 2008 Estuarine Ecohydrology, by Eric Wolanski, 2007. Elsevier Science & Technology, P.O. Box 211, 1000 AE Amsterdam, The Netherlands. Hardback, 157 pages. Price EUR 74.95; USD 71.96; GBP 51.99. ISBN 978-0-444-53066-0. Not many authors close the gap between the abiotic world of hydraulics and sediment- transport mechanisms on the one hand and that of ecology and biology on the other. Wolanski manages to clearly introduce the reader to estuarine hydraulics, sediment dynamics, and ecology, as well as to their interrelations and the human influence on estuarine sediment dynamics and ecology. His aim to provide clear, specialist knowledge to enable an interaction between aquatic, marine and wetlands biologists, geologists, geomorphologists, chemists, modellers and ecologists has definitely been achieved. In his latest book, he brings ecohydrology forward as the principle to guide the management of entire river basins (from headwaters to the coastal zone) as a means to cope with increasing environmental degradation of estuaries. Ecohydrology is more than integrated river- basin management because it uses the natural capacity of the physical system to absorb or process excess nutrients and pollutants resulting from human activities. Restoration of estuaries using ecohydrology requires a thorough understanding of the estuary as an ecosystem. This book describes the principal components of ecohydrology, being the fluvial and estuarine waters, sediment transport and deposition, transport of nutrients, wetlands, the aquatic food web, and the modeling thereof.

    www.nature.com/scientificreports OPEN Occurrence, distribution, and health risk assessment of quinolone antibiotics in water, sediment, and fsh species of Qingshitan reservoir, South China Liangliang Huang1,3, Yuanmin Mo2,4, Zhiqiang Wu4, Saeed Rad1*, Xiaohong Song3, Honghu Zeng1, Safdar Bashir5, Bin Kang6 & Zhongbing Chen7* The residual antibiotics in the environment have lately caused widespread concerns. However, little information is available on the antibiotic bioaccumulation and its health risk in drinking water resources of South China. Therefore, the occurrence, distribution, and health risk of four quinolone antibiotics including ofoxacin (OFX), norfoxacin (NOR), ciprofoxacin (CIP), and enrofoxacin (ENR) in the Qingshitan reservoir using high-performance liquid chromatography were investigated. Results revealed that the concentrations in water, sediment, and edible fsh ranged from 3.49–660.13 ng/L, 1.03–722.18 μg/kg, and 6.73–968.66 μg/kg, respectively. The ecological risk assessment via the risk quotient (RQ) method showed that the values in sediment were all greater than 1, posing a high risk to the environment. The health risk index of water samples was at the maximum acceptable level, with OFX at the top while the rest were at the medium risk level. The main edible fsh kinds of the reservoir had high dietary safety and the highest contaminations were found in carnivorous feeding habits and demersal habitat fshes with OFX as the highest magnitude. Source identifcation and correlation analysis using SPSS showed signifcant relationships between NOR with pH and turbidity (in water), as well as total phosphor (TP) and total organic carbon (TOC) in sediment. NOR was the highest in sediment which mostly sourced from livestock wastewater, croplands irrigation drain water, and stormwater.
