Rates, Importance, and Controls of Nitrogen Fixation in Oligotrophic Arctic Lakes, Toolik, Alaska
Biological nitrogen (N) fixation of atmospheric N2 by free-living cyanobacteria in aquatic environments is common, and in many ecosystems, it can account for a significant portion of the biologically available N inputs. Although N fixation can compensate for N limitation, N limitation is maintained over relatively long time scales in many oligotrophic lake ecosystems. This dissertation examines the importance of benthic and pelagic N fixation in the N economies of oligotrophic lakes in arctic Alaska (Chapter 1) and examines nutrient, light, and grazer controls on benthic N fixation (Chapters 2 and 3). Both benthic and pelagic N fixation are prevalent in many lakes across the Alaskan arctic l...
River Networks as Ecological Corridors
A summary of state-of-the-art research on how the river environment impacts biodiversity, species invasions, population dynamics, and the spread of waterborne disease. Blending laboratory, field and theoretical studies, it is the go-to reference for graduate students and researchers in river ecology, hydrology, and epidemiology.
Analyzing Ecological Data
This book provides a practical introduction to analyzing ecological data using real data sets. The first part gives a largely non-mathematical introduction to data exploration, univariate methods (including GAM and mixed modeling techniques), multivariate analysis, time series analysis, and spatial statistics. The second part provides 17 case studies. The case studies include topics ranging from terrestrial ecology to marine biology and can be used as a template for a reader’s own data analysis. Data from all case studies are available from www.highstat.com. Guidance on software is provided in the book.
Sustainable Ammonia Production
This book presents sustainable synthetic pathways and modern applications of ammonia. It focuses on the production of ammonia using various catalytic systems and its use in fuel cells, membrane, agriculture, and renewable energy sectors. The book highlights the history, investigation, and development of sustainable pathways for ammonia production, current challenges, and state-of-the-art reviews. While discussing industrial applications, it fills the gap between laboratory research and viable applications in large-scale production.
Water Culture in Roman Society
Water played an important part of ancient Roman life, from providing necessary drinking water, supplying bath complexes, to flowing in large-scale public fountains. The Roman culture of water was seen throughout the Roman Empire, although it was certainly not monolithic and it could come in a variety of scales and forms, based on climatic and social conditions of different areas. This article seeks to define ‘water culture’ in Roman society by examining literary, epigraphic, and archaeological evidence, while understanding modern trends in scholarship related to the study of Roman water. The culture of water can be demonstrated through expressions of power, aesthetics, and spectacle. Further there was a shared experience of water in the empire that could be expressed through religion, landscape, and water’s role in cultures of consumption and pleasure.
Nature Based Solutions for Wastewater Treatment
There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS ...
Streamflow Measurement, Third Edition
‘Too little water or too much’? In either case streamflow measurement is crucial. Climate change could significant affect water resources and flood management. Streamflow measurement is necessary for efficient water management. This third edition deals with all the main current methods for measuring the flow in rivers and open channels, in accordance with ISO and CEN standards and to satisfy the current requirements of the International Organization for Standardization and the European Union’s Water Directive. A new chapter on the Acoustic Doppler Current Profiler (ADCP) is included; the chapter on uncertainties has been redrafted in accordance with the recent International Standard on uncertainties in measurement (GUM); the chapters on the Stage-Fall-Discharge method and Hydrometric Data Processing have also been updated; and a new section on flood flows has been added.
