Abstract

Larval dispersal is arguably the most important but least understood demographic process in the sea.&#xD;The likelihood of a larva dispersing from its birthplace to successfully recruit in another location&#xD;is the culmination of many intrinsic and extrinsic factors that operate in early life. Empirically&#xD;estimating the resulting population connectivity has been immensely difficult because of the&#xD;challenges of studying and quantifying dispersal in the sea. Consequently, most estimates are based&#xD;on predictions from biophysical models. Although there is a long history of dispersal modelling,&#xD;there has been no comprehensive review of this literature. We conducted a systematic quantitative&#xD;review to address the following questions: (1) Is there any bias in the distribution of research effort&#xD;based on geographical or taxonomic coverage? (2) Are hydrodynamic models resolving ocean&#xD;circulation at spatial scales (resolution and extent) relevant to the dispersal process under study?&#xD;(3) Where, when and how many particles are being tracked, and is this effort sufficient to capture&#xD;the spatiotemporal variability in dispersal? (4) How is biological and/or behavioural complexity&#xD;incorporated into Lagrangian particle tracking models. (i.e. are key attributes of the dispersal&#xD;process well captured.)? Our review confirms strong taxonomic and geographic biases in published&#xD;work to date. We found that computational ‘effort’ (i.e. model resolution and particle number) has&#xD;not kept pace with dramatic increases in computer processor speed. We also identified a number of&#xD;shortcomings in the incorporation of biology, and behaviour specifically into models. Collectively,&#xD;these findings highlight some important gaps and key areas for improvement of biophysical models&#xD;that aspire to inform larval dispersal processes. In particular, we suggest the need for greater&#xD;emphasis on validation of model assumptions, as well as testing of dispersal predictions with&#xD;empirically derived data.

Abstract

This fascinating book is the first comprehensive analysis of the economic, social and political interrelationships between tourism and global environmental change: one of the most significant issues facing humankind today. Its contributors argue that the impacts of these changes are potentially extremely serious both for the tourism industry, and for the communities dependent upon it. Integrating knowledge from the social and physical sciences, this significant book explores they key issues surrounding global environmental change, as well as government and industry willingness to meet the challenges posed by it. Divided into four main sections, it investigates: the tourism and global environmental change relationship in specific environments global issues related to environmental change differing perceptions of global environmental change held by tourists and the tourist industry. Comprehensive in scope, topical and integrative, this key text is essential reading for students, scholars and researchers in all aspects of tourism, geography and environmental studies.

Abstract

Drawing upon recent progress in development economics and political science, the book provides fresh analysis of the Caucasus and Central Asia (CCA) countries transition to a market economy by tracing the impact of natural resource endowment. The book examines the synergies between energy-rich and energy-poor states and highlights the practical consequences of both well-managed and poorly-managed deployment of energy. Featuring contributions from prominent specialists on resource-driven economies, the book argues that unless CCA elites change the way in which they deploy natural resource, revenues regional development will fall short of its potential with possible disastrous consequences. The contributors apply the experience of the developing market economies to demonstrate that the region still holds considerable potential to become an important, stable supplier of raw materials and a source of industrial demand to the global economy. However, the CCA is equally likely to become a threat to the global economy as a consequence of the misuse of energy revenues to promote the interests of predatory political elites.

Abstract

In June 2015 we held a workshop on the beautiful island of Mallorca, Spain with a focus on sea level variability and change. Over 120 sea level experts from around the world attended this workshop, from a range of different disciplines. The main aims of the workshop were to: 1.) Evaluate the current state-of-knowledge of sea level science; 2.) Identify gaps and unresolved questions in any aspect of sea level science; and 3.) Design future research to address these issue. All aspects of sea level changes were covered, from global to regional, observations and modelling, processes driving mean sea level changes and extremes, from the geological scale to the instrumental era and future projections and including impacts on the coastal zones. This E-Book presents papers that came out of that workshop. Overall, these papers illustrate the multi-disciplinary nature of sea level research, cross-cutting many fields of research including: oceanography, meteorology, geology, coastal morphodynamics, engineering and the social-economic aspects. Collectively, theses articles represent an interesting range of perspectives and original studies that contribute to understanding the dynamic nature of sea level and its impacts across a wide range of time and space scales. Enjoy reading them!

Abstract

​This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change.The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future.The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.

Abstract

Biosurfactants are structurally diverse group of bioactive molecules produced by a variety of microorganisms. They are secondary metabolites that accumulate at interfaces, reduce surface tension and form micellar aggregates. This research topic describes few novel microbial strains with a focus on increasing our understanding of genetics, physiology, regulation of biosurfactant production and their commercial potentials. A major stumbling block in the commercialization of biosurfactants is their high cost of production. Many factors play a significant role in making the process cost-effective and the most important one being the use of low-cost substrates such as agricultural residues for the production of biosurfactants. With the stringent government regulations coming into effect in favor of production and usage of the bio-based surfactants, many new companies aim to commercialize technologies used for the production of biosurfactants and to bring down costs. This Research Topic covers a compilation of original research articles, reviews and research commentary submitted by researchers enthusiastically working in the field of biosurfactants and highlights recent advances in our knowledge of the biosurfactants and understanding of the biochemical and molecular mechanisms involved in their production, scale-up and industrial applications. Apart from their diverse applications in the field of bioremediation, enhanced oil recovery, cosmetic, food and medical industries, biosurfactants can also boast off their unique eco-friendly nature to attract consumers and give the chemical surfactants a tough competition in the global market. This biosurfactant focused research topic aims to summarize the current achievements and explore the direction of development for the future generation of biosurfactants and bioemulsifiers. Some of the biosurfactant optimization processes presented are well-structured and already have a well-established research community. We wish to stimulate on-going discussions at the level of the biosurfactant production including common challenges in the process development, novel organisms and new feedstock and technologies for maximum benefit, key features of next generation biosurfactants and bioemulsifiers. We have compiled the research outputs of international leaders in the filed of biosurfactant particularly on the development of a state-of-the-art and highly-efficient process platform.

Abstract

Between 1860 and 1910, Australian governments sanctioned and then tried to stop the trafficking of South Sea Islanders ​to Queensland as forced labourers. Over 60,000 Islanders were lured from their villages: tricked, transported, forced to work in the harsh Queensland bush, and then repatriated. Most Islanders returned with little savings to find their communities deeply scarred by the blackbirding trade and the internecine tribal conflict it had provoked.Georges Baudoux (1865-1949) was brought up amongst the Islanders who experienced the raw and competing greed of French, British and Australian colonialism. Son of a French prison commander stationed in New Caledonia, Baudoux lead a colourful life amongst the Pacific islands and deep in the brousse (bush) before becoming an author and capturing the stories of his travels and, importantly, the experiences of friends and colleagues as life in the islands changed forever. In recognition of his work, he was awarded the esteemed Palmes Académiques, the French medal for literary and academic achievement.Jean M'Barai is one of his best works. Expertly translated by Dr Karin Speedy and published here in English for the first time, this book exposes the rich, complex and brutal world of a South Sea Islander caught up in the duplicitous trade that came to be known as Blackbirding. It is an exciting, provocative and often astonishing account, drawing on the lived experience of people known to the author.In her critical introduction, Dr Speedy uncovers not just the author and his intriguing life (a life that spanned the uprising of the Paris communards in 1870 to post-Second World War reconstruction in the Pacific), but also the challenges for scholars working in, and undertaking translations in, the Francophone/Anglophone colonial/postcolonial sphere. Here, where empires, languages and Pacific peoples collide, the nuances of culture and terminology really matter if we are to find meaning amongst the shifting tides of use.Accompanied by photographs, postcards, cartoons and maps, this is a book to read and re-read, to contemplate ingenuity and inhumanity and the price all cultures pay as they are tested by forces beyond their control. It is a story that still resonates today, as we reflect on the experiences and resilience of the Pacific South Sea Islanders who contributed to modern Australia: the many that left and the descendants of those who stayed.

Abstract

This volume draws upon the scholarship on the international trade between the Roman Empire and Eastern regions such as Arabia, Ethiopia and India. Such trade has been often described by ancient sources as a flourishing and very expensive one. More in detail, the book focuses on the life and the development of the ports on the Red Sea, controlled by Rome. These ports acted for centuries as international hubs, linking points between West and East, and they were the gates though which the eastern merchandise would reach the Roman markets. Keeping these remote settlements alive required a big effort on the part of the imperial administration, and some degree of planning to choose how and when to invest in the area. So, over the centuries, the geography of such ports changed dramatically. Most works published so far have explained such changes in terms of decline and economic shrinking, due to the “late antique phase” of the Roman Empire. This monograph looks for a different explanation and stretches the analysis into the late antique period, showing hot it was not a period of decline and economic recession, but rather of reorganization. The volume aims finally to reach a new and more full level of understanding of the Roman economic policy in the Red Sea between the first century BC and the sixth AD.
