Four Regional Marine Biodiversity Studies: Approaches and Contributions to Ecosystem-Based Management

We compare objectives and approaches of four regional studies of marine biodiversity: Gulf of Maine Area Census of Marine Life, Baltic Sea History of Marine Animal Populations, Great Barrier Reef Seabed Biodiversity Project, and Gulf of Mexico Biodiversity Project. Each program was designed as an "ecosystem" scale but was created independently and executed differently. Each lasted 8 to 10 years, including several years to refine program objectives, raise funding, and develop research networks. All resulted in improved baseline data and in new, or revised, data systems. Each contributed to the creation or evolution of interdisciplinary teams, and to regional, national, or international science-management linkages. To date, there have been differing extents of delivery and use of scientific information to and by management, with greatest integration by the program designed around specific management questions. We evaluate each research program's relative emphasis on three principal elements of biodiversity organization: composition, structure, and function. This approach is used to analyze existing ecosystem-wide biodiversity knowledge and to assess what is known and where gaps exist. In all four of these systems and studies, there is a relative paucity of investigation on functional elements of biodiversity, when compared with compositional and structural elements. This is symptomatic of the current state of the science. Substantial investment in understanding one or more biodiversity element(s) will allow issues to be addressed in a timely and more integrative fashion. Evaluating research needs and possible approaches across specific elements of biodiversity organization can facilitate planning of future studies and lead to more effective communication between scientists, managers, and stakeholders. Building a general approach that captures how various studies have focused on different biodiversity elements can also contribute to meta-analyses of worldwide experience in scientific research to support ecosystem-based management

Advances in Software Engineering and Aeronautics

Avionics, like any other safety-critical real-time systems, pose unique challenges on system design, development, and testing. Specifically, the rigorous certification process mandated for avionics software calls for additional attention. The DO-178C Software Considerations in Airborne Systems and Equipment Certification provides detailed guidelines to ensure safety measures. This chapter gives a different angle to avionics development and certification, highlighting model-based approaches for advancing the design, development, testing, and maintenance of airborne software systems. Modern software engineering processes such as agile and scrum are discussed as the new techniques in speeding up the certification hurdle, while achieving higher return on investment

Introduction: wildlife tourism management and phenomena: a web of complex conceptual, theoretical and practical issues

This introductory chapter highlights the major conceptual and practical issues regarding wildlife tourism worldwide. A series of events have brought concerns that the status and conditions of wild animals in the tourism needs further critical discussion, with current study cases being in the spotlight for analysis. There is a web of complexities permeating the field of wildlife tourism in terms of planning and management, not to mention the ethical issues. The current state of wildlife tourism draws attention to the need of in-depth reflections and insights on the use of animals as attractions as well as the needs and attitudes of tourism personnel and visitors. A change in perception of the natural world on the whole is needed, from a fully utilitarian view to a more compassionate one. The Earth is not home only for humans, so we need to break away from a predominantly anthropocentric view in our society. Indeed, within these epistemological and philosophical frames, ‘ecological’ and ‘conservation’ aspects have been regarded as fundamental for bringing a certain consensus to the equation on a morally acceptable human-nature relation for the 21st Century. This introductory chapter begins by presenting conceptual and disciplinary approaches to environmental social sciences, as well as human and political ecology, pertinent to this volume. It then presents some of the polemic cases involving wildlife and visitors, such as Cecil the lion, the tigers in the Thai Buddhist Temple, and, the killing of gorilla Harambe. The chapter concludes by presenting a summary of each chapter providing unique and original content to making this volume an exciting reading experience to update the readers\u27 knowledge and understanding of the current state of wildlife tourism and issues facing it, as part of the bigger picture of our practical and ethical viewpoints of humans and the rest of nature on our planet
