Book Synopsis Diversity and Distribution of Coralline Algae in Southern New Zealand by : Brenton Twist
Download or read book Diversity and Distribution of Coralline Algae in Southern New Zealand written by Brenton Twist and published by . This book was released on 2019 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coralline algae (Corallinophycideae) are calcifying red algae that form the foundation of many shallow marine ecosystems globally, providing settlement sites for a range of invertebrate larvae, stabilisation of reefs and habitat for grazing and cryptofaunal species. This group of macroalgae are vulnerable to increased anthropogenic disturbances, in particular ocean acidification. Despite their ecological importance and vulnerability, little is known about their diversity, distribution and ecology, globally and within New Zealand. The primary objective of this work was to document the diversity and distribution of coralline algae in New Zealand, and examine the abiotic and biotic factors potentially influencing this distribution across different spatial scales. This body of work used DNA based phylogenetic methods to identify species of corallines collected in the southern region of New Zealand, incorporating data previously collected from central and northern New Zealand. A high level of diversity was revealed in southern New Zealand (77 species identified and 99 predicted), which is in line with what is currently being uncovered globally, with diversity that is two to four times higher than previously estimates that were based on morpho-anatomical identifications. Multivariate clustering and constrained ordination techniques, grouping sites based on similarities in coralline algae community structure and relating this to selected environmental parameters, identified sea surface temperature and light at the seabed as variables significantly correlated with these community groupings across the New Zealand region. Similarly, linear model analysis identified depth, likely a proxy for light, and the type of substrate as being the most important variables explaining the abundance of coralline algae (independent of species identity) across an often overlooked biogenic environment across Foveaux Strait. At local spatial scales (10-100’s m) patterns in coralline algal community structure revealed stochastic dispersal processes likely determine which species establish, followed by competitive interactions driving differences in abundances. These local scale processes are unlikely to influence diversity patterns seen at larger scales across the New Zealand region. Furthermore, high local scale diversity was observed, with few abundant and many rare species. This research provides an important molecular framework and information on distributional patterns of coralline algae needed to further advance knowledge on this ecologically important group.
Book Synopsis The Ecophysiology of Corraline Algae in Southern New Zealand by : Hang Thi Thuy Nguyen
Download or read book The Ecophysiology of Corraline Algae in Southern New Zealand written by Hang Thi Thuy Nguyen and published by . This book was released on 2019 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coralline algae (Rhodophyta) are an important indicator of global environmental change in coastal ecosystem due to their global distribution and sensitivity to changing ocean climate. In temperate latitudes, coralline algae are a dominant component of macroalgae communities, are autogenic ecosystem engineers. They provide hard substrate for colonization of other marine algae and invertebrates, and food that helps sustain diverse communities of associated organisms. The metabolic processes, growth and reproduction of coralline algae heavily depend on environmental factors including light, temperature and ambient nutrients in seawater. These changes, in turn, directly affect physiological responses of coralline algae.
Book Synopsis Rhodolith/Maërl Beds: A Global Perspective by : Rafael Riosmena-Rodríguez
Download or read book Rhodolith/Maërl Beds: A Global Perspective written by Rafael Riosmena-Rodríguez and published by Springer. This book was released on 2016-10-07 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rhodolith beds are recognized internationally as a unique ecosystem, and they are the focus of this interdisciplinary book. These marine beds occur worldwide, from the tropics to the poles, ranging in depth from intertidal to deep subtidal habitats and they are also represented in extensive fossil deposits. In the light of international interest in rhodoliths and maerl concerning their role in coastal ecosystems and with respect to biodiversity, fisheries, and the production of sediment, this book provides the most comprehensive view possible. As readers will discover, rhodoliths/maerl are fundamental to a range of ecological processes, acting as ecosystem engineers including playing key roles in recruitment and providing nursery habitats. Rhodoliths/maerl have been used commercially in some parts of the world, and they are understood to be vulnerable to coastal modifications and human-induced change, and hence their status may serve as an indicator of ecosystem health. Rhodoliths/maerl contribute to global carbon budgets although the extent remains to be evaluated, as do the potential impacts of changing global climates and ocean acidification.
Book Synopsis Marine Macrophytes as Foundation Species by : Emil Olafsson
Download or read book Marine Macrophytes as Foundation Species written by Emil Olafsson and published by CRC Press. This book was released on 2016-11-25 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine macrophytes (macroalgae, seagrasses, and mangroves) comprise thousands of species distributed in shallow water areas along the world’s coastlines. They play a key role in marine ecosystems regarding biodiversity and energy flow. A large proportion of macrophyte species can be characterised as ecosystem engineers—organisms that directly or indirectly affect the availability of resources to other species by modifying, maintaining, and creating habitats. This book is divided into three main themes: • Marine macroalgae and seagrasses as sources of biodiversity gives an overview of the diversity of the main organisms associated with macrophytes, and their functional role and interactions within their hosts. • Primary and secondary production of Macrophytes synthesizes research on food web structures derived from/or associated with, macrophytes and the transfer of macrophytic primary and secondary production from one ecosystem to another. • Threats to macrophytic ecosystem engineers addresses human-induced effects including eutrophication, physical destruction, invasive species, and global warming. The book is among the first one to concentrate on the value of macrophytes for the well-being of marine habitats. The book is aimed at academics but may be useful for students, policy makers, and laymen alike.
Book Synopsis Ocean Acidification by : National Research Council
Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Synopsis Characterizing the Response of Coralline Algae to Ocean Acidification and Nutrient Changes in the California Current System by : Sandy Letzing
Download or read book Characterizing the Response of Coralline Algae to Ocean Acidification and Nutrient Changes in the California Current System written by Sandy Letzing and published by . This book was released on 2013 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean acidification (OA) has emerged as an important focus of research and policy in this decade. Ocean acidification specifically refers to changes in the inorganic carbon system in the ocean resulting from its absorption of human-released CO2 from the atmosphere. Anthropogenic atmospheric CO2 levels are rapidly increasing; much of this is dissolved and absorbed in the ocean (~30%) where it reacts with seawater altering fundamental properties including pH, pCO2 and saturation state of carbonate minerals. This change is of concern because of the potential of OA to disrupt biological processes, particularly those processes associated with calcification (Byrne, 2011; Diaz-Pilido, Anthony, Kline, Dove, & Hoegh-Guldberg, 2012). For this study, I chose to investigate red coralline algae as a model organism because OA is predicted to have effects on calcification and photosynthesis, and because of the importance of coralline algae as an ecological engineer, which can be found in shallow water habitats globally. While the response of coralline algae to OA is a serious concern, there remains very limited data on the interactions of OA with other ocean conditions (e.g., temperature, nutrients, and light) that may alter or modify the effects of low pH on coralline algae communities. One nutrient in particular, phosphorus is known to have inhibiting effects on calcification in long-term studies. My objective was to describe the short-term effects of a range of elevated pCO2 and phosphorus levels both alone, and together, on calcification and photosynthetic rates of Corallina vancouveriensis. I exposed these algae to a range of pCO2 and phosphate concentrations and measured changes in total alkalinity, pH, and DO in acute exposure trials (

Download or read book Biodiversity written by R C Sobti and published by CRC Press. This book was released on 2022-12-30 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "biodiversity" or "biological diversity" describes the variety of living beings on Earth encompassing microorganisms, plants, animals, and ecosystems, such as coral reefs, forests, and deserts. In fact, it also represents a wealth of biological resources available to us. Today, instead of exploring and preserving its unmapped biodiversity, mankind has gone away from mother nature, conquering the domain through relentless exploitation. This has resulted in an ecological imbalance and thereby has posed serious threat to biodiversity. Declining biodiversity is, therefore, a concern for countless reasons. Biodiversity’s wealth of genetic information can be conserved by storing biological material from endangered species. Cell lines, gametes, and embryos are preserved so that in case a species becomes extinct or there is a need to increase the population of the species, then cloning and artificial reproductive techniques can be used to revive and reproduce the said species. The present volume discusses the biodiversity of specific animal groups, such as cnidarians and fish, as well as potential risks to and methods for conserving some of them. The following important aspects are addressed: 1. The importance of biodiversity in maintaining ecosystem balance for sustainability 2. The emerging role of biodiversity as a source of important materials, pharmaceuticals, food, and so on as such or through genetic manipulation to meet the contemporary and future challenges 3. The impact of environment degradation on biodiversity and conservation in a changing environment 4. Conventional and emerging biotechnological techniques to conserve biodiversity The book is intended for academics, scientists, and naturalists working in the fields of biology, biochemistry, biophysics, and biomedical sciences.
