Marine Macroecology

Pioneered in the late 1980s, the concept of macroecology—a framework for studying ecological communities with a focus on patterns and processes—revolutionized the field. Although this approach has been applied mainly to terrestrial ecosystems, there is increasing interest in quantifying macroecological patterns in the sea and understanding the processes that generate them. Taking stock of the current work in the field and advocating a research agenda for the decades ahead, Marine Macroecology draws together insights and approaches from a diverse group of scientists to show how marine ecology can benefit from the adoption of macroecological approaches. Divided into three parts, Marine Macroecology first provides an overview of marine diversity patterns and offers case studies of specific habitats and taxonomic groups. In the second part, contributors focus on process-based explanations for marine ecological patterns. The third part presents new approaches to understanding processes driving the macroecolgical patterns in the sea. Uniting unique insights from different perspectives with the common goal of identifying and understanding large-scale biodiversity patterns, Marine Macroecology will inspire the next wave of marine ecologists to approach their research from a macroecological perspective.

Macroecology: Concepts and Consequences brings together for the first time major researchers in the field to present overviews of current thinking about the form and determinants of macroecological patterns. Each section presents different viewpoints on the answer to a key question in macroecology, such as why are most species rare, why are most species small-bodied, and why are most species restricted in their distribution?

Marine sediments support complex interactions between macro-and microorganisms that have global implications for carbon and nutrient cycles. What is the state of the science on such interactions from coastal and estuarine environments to the deep sea? How does such knowledge effect environmental management? And what does future research hold in store for scientists, engineers, resource managers, and educators?Interactions between Macro- and Microorganisms in Marine Sediments responds to these questions, and more, by focusing on:? Interactions between plants, microorganisms, and marine sediment? Interactions between animals, microorganisms, and marine sediment? Interactions between macro- and microorganisms and the structuring of benthic communities? Impact of macrobenthic activity on microbially-mediated geochemical cycles in sediments? Conceptual and numeric models of diagenesis that incorporate interactions between macro- and microorganismsHere is an authoritative overview of the research, experimentation and modeling approaches now in use in our rapidly evolving understanding of life in marine sediments.

Ever-increasing interest in oceanography and marine biology and their relevance to global environmental issues create a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its founding by the late Harold Barnes more than 50 years ago. Its objectives are to consider, annually, the basic areas of marine research, returning to them when appropriate in future volumes; to deal with subjects of special and topical importance; and to add new subjects as they arise. The favourable reception and complimentary reviews accorded to all the volumes shows that the series is fulfilling a very real need. Volume 54 follows closely the objectives and style of the earlier volumes, continuing to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments. It is consistently among the highest ranking series in terms of impact factor in the marine biology category of the citation indices compiled by the Institute for Scientific Information/Web of Science.

Dispersal ability is a frequently cited determinant of the extent of species' ranges, but this has rarely been rigorously tested with quantitative data. I investigated the putative association between dispersal potential and range size using three large quantitative datasets. My analyses suggest that dispersal is not a general determinant of marine species' geographic distributions. Conceptual examinations also reveal that the proposed mechanisms for a positive dispersal-range size relationship have inherent flaws. Dispersal plays key roles in biogeography, but the eventual size of a species' range may often be mediated by other factors, likely operating at larger scales than the mean dispersal distance.

This comprehensive volume discusses the patterns and processes analyzed in macroecology with a distinct look at the theoretical and methodological issues underlying the discipline as well as deeper epistemological matters. The book serves as a synthesis of macroecological literature that has been published since Brown and Maurer proposed and defined the term “macroecology” in 1989. Author José Alexandre Felizola Diniz-Filho draws from the different disciplines and branches (ecology, evolutionary biology, physiology, behavioral sciences, climatology, and paleontology) that make up macroecology to present a full, holistic picture of where the discipline stands. Through ten chapters, Diniz-Filho moves from a discussion of what macroecology actually is to macroecological modeling to the more applied side of the discipline, covering topics such as richness and diversity patterns and patterns in body size. The book concludes with a synthesis of how macroecological research is done in a theoretical and operational sense as well as unifying explanations for each of the macroecological patterns discussed, moving on to evaluate which theories and models are still useful and which ones can be abandoned. The book is intended for academics, young researchers and students interested in macroecology and conservation biogeography. In addition, because of the integrative nature of macroecology and the theoretical and methodological background in the book, it can be of interest to researchers working in related fields including but not limited to ecology and evolutionary biology.

Macroecology is the study of emergent statistical patterns in ecology. This field has produced numerous interesting results in the terrestrial realm, but has only recently begun to be applied in the marine environment. In this thesis, I use the macroecological approach to examine the effects of human impacts, and the scale of analysis, on the oceans. I begin with an overview of the macroecology of exploited marine systems. Next, I compare species-area relationship data gathered from four different reef systems, and find that there is a consistent impact of exploitation on the scaling of reef fish biodiversity with area. Following this, I use two presence-only habitat suitability models to predict global habitat for cold-water stony corals on seamounts. These corals are often associated with elevated levels of biodiversity. I find suitable habitat on seamounts is located in the North Atlantic down to -2,500 m in depth, and in a circum-global strip in the mid-latitude southern hemisphere down to -1,500 m depth. Patterns are qualitatively similar for both models. I then use the more discriminative model to fit an enlarged data set consisting of cold-water stony corals from all deep-sea environments, and down to 5,500 m in depth. The patterns of global habitat suitability are similar to those for corals on seamounts, suggesting similar niche requirements at this scale. I apply model results to a future climate scenario (IPCC IS92a 'business-as-usual') to examine the likely effects of anthropogenic-induced changes in ocean chemistry. I find that habitat suitability is negatively impacted at low to moderate levels worldwide by 2099, except for in the North Atlantic where the effects are more severe. The final part of my thesis considers whether estimates of endemism in undersampled environments are real or an artefact of incomplete sampling. I create two identical simulated populations, and sample from them to examine the effects of species richness, evenness, and sampling intensity. Large numbers of false endemics can be predicted at low sampling effort. I then apply these results to data from the abyssal Pacific, to determine how much sampling would be required to have confidence in estimates of endemism.

For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designe

Macroecology is an approach to science that emphasizes description and explanation of patterns and processes at large spatial and temporal scales. Some liken it to seeing the forest through the trees, an apt ecological use of the proverbial phrase. The term itself was introduced to modern literature by our authors James Brown and Brian Maurer, in a seminal science paper in 1989. We then published books by both of these authors, including Brown s Macroecology in 1995, which quickly traveled to the shelf of classics in ecology, credited with cohering and inspiring a subfield of ecology proper.While macroecology is to many a modern subfield, the large-scale perspective it advocates is implicit in earlier publications. For example, in 1898 de Liocourt studied the influence of management practices on the structure of French fir forests, and characterized the distribution of tree size in three different stands. His findings that in natural areas the number of trees declined exponentially with increasing diameter of the trunk allowed him to draw conclusions about the influence of management practices on tree distribution patterns. Similarly, other classic macroecological patterns including the species-area relationship, latitudinal gradient of species richness, relationship between body size and metabolic rate, species-abundance distribution, and species-body size distribution were identified decades, sometimes even centuries ago. Consequently, despite the scant twenty years that has elapsed since the term was coined, macroecology has a deep and rich history."Foundations of Macroecology" traces and coheres that history, charting an evolutionary trajectory to the rigorous macroecological research landscape science enjoys today. The forty-six papers span eight decades, from 1920 to 1998, and include divergent perspectives of space, time, and taxonomic and habitat affiliation. They are organized into two main parts: Macroecology before Macroecology and Dimensions of Macroecology. The latter is further subdivided into six sections reflecting the subject matter: Allometry and Body Size, Evolutionary Dynamics, Abundance and Distributions, Species Diversity, and Methodological Advances. For each reprinted paper, a macroecologist specializing in that area has written original commentary that places the paper in a broader context and explains why it is foundational. "
