Periphyton: Functions and Application in Environmental Remediation presents a systematic overview of a wide variety of periphyton functions and applications in environmental remediation, providing readers with an understanding of the biological/ecological features of periphyton, the methodology of their study, and their application in environmental conservation.

With increases in environmental stress, anthropogenic impacts, and the global decline in biodiversity, there is a pressing need for methods to assess and improve environmental quality that are rapid, reliable, and cost-effective. Periphyton is an important component of benthic communities and plays a crucial role in the functioning of microbial food webs. Because of a number of advantages, such as a short lifecycle, relative immobility, more rapid responses to environmental stress and anthropogenic impact than any metazoa, ease of sampling, availability of taxonomic/molecular identification, and standardized methodologies for temporal/spatial comparisons, there has, in recent decades, been an increased interest in periphyton as a tool in biological conservation in aquatic ecosystems.

Presents case studies that help readers implement similar ecological designs Focuses on the function of periphyton in remediating destructed ecosystems Provides readers with an understanding of periphyton in practice, especially the value of periphyton in enhancing environmental and ecosystem qualities Discusses the role of periphyton in purifying water and its effect on abiotic elements

Broadband, or high-speed internet, has been called the most important infrastructure challenge of the century. It has the potential to connect remote communities, streamline health care services, and support innovation across education, economics, and numerous other fields. Given the growing and widespread investments in broadband, how can citizens and policymakers determine whether the promise of broadband is being fulfilled? Transforming Everything? offers a comprehensive guide to the complexities and possibilities of broadband as a social technology. It addresses challenges for evaluating broadband initiatives across diverse contexts and proposes guidance and methods for evaluation for policymakers and researchers. Contributors draw on pioneering research in program evaluation and information technology to explore broadband applications in health, education, and civic engagement. They also address key measurement and evaluation challenges in the field today, including issues in privacy and security and inadequate research methods for target populations. Collectively, the chapters in this volume raise important questions for improving research and evaluation in broadband use and producing actionable evidence in a highly dynamic environment. Transforming Everything? prepares readers with a critical understanding of broadband technology and the necessary evidence to assess whether broadband programs and policy are truly empowering the communities they serve.
