Book excerpt: Premise of the study- The unique geography of the Olympic Peninsula has created a flora with exceptional endemism that may face high rates of extinction due to climate change. Conserving endemic taxa requires a deeper understanding of general and individual species' responses to warming in topographically complex environments. The Olympic Mountains provide an unparalleled opportunity to test predicted responses and inform conservation plans for threatened alpine taxa. Methods- I developed Species Distribution Models (SDMs) for five endemic alpine plants of the Olympic Peninsula to estimate the potential impact of climate change on these rare taxa. First, I created high-resolution raster surfaces on the Olympic Peninsula with climatic and topographic variables for the current period and the year 2080. I used Principal Components Analysis to visualize changes in climate niche-space in the Olympic alpine and the exposure of the five endemics to changing conditions. I then constructed climate and topographic-based SDMs, to estimate changes in the distribution of habitat for each taxon. Finally, I identified potential thermal refugia as areas where suitable habitat conditions would remain by the year 2080. Key Results- The Olympic alpine will experience novel environmental conditions in the future, with a pronounced decrease in winter snow and an increase in growing season moisture stress. Suitable habitat will be greatly reduced for all five focal taxa, with thermal refugia remaining only on the highest peaks of the eastern Olympics. Topographic SDMs suggested further decreases in the total amount of projected suitable habitat. Furthermore, I identified differences in the proportion of suitable micro-topography within each taxon's climate envelope that greatly affect the species-specific climate change prognosis. Conclusions- The Olympic alpine endemics are stranded on ever shrinking habitat islands, and are projected to lose 85-99% of their suitable habitat by 2080. Their survival depends on their ability to persist in isolated thermal refugia on the highest peaks. Within these refugia, the distribution of micro-topography may be a critical factor in determining the long term survival prospects of threatened taxa. The Olympic Mountains and their endemic taxa are a model system illustrating the biogeographic characteristics that underpin vulnerability to climate change. Globally, taxa with narrow distributions that are already occupying the coldest locally available habitats should be considered extremely vulnerable, and may be at the forefront of climate-driven extinctions.

Download or read book Refugia written by Kyce Bello and published by University of Nevada Press. This book was released on 2019-09-04 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2020 New Mexico-Arizona Book Awards Winner of the inaugural Interim 2018 Test Site Poetry Series Prize Refugia is a bright and hopeful voice in the current conversation about climate change. Kyce Bello’s stunning debut ponders what it means to inhabit a particular place at a time of enormous disruption, witnessing a beloved landscape as it gives way to, as Bello writes, “something other and unknown, growing beyond us.” Ultimately an exploration of resilience, Refugia brings to life the author’s home ground in Northern New Mexico and carefully observes the seasons in parallel with personal cycles of renewal and loss. These vivid poems touch upon history, inheritance, drought, and most of all, trees—be they Western conifers succumbing to warming temperatures, ramshackle orchards along the Rio Grande, or family trees reaching simultaneously into the past and future. Like any wilderness, Refugia creates a terrain that is grounded in image and yet many-layered and complex. These poems write us back into an ecological language of place crucial to our survival in this time of environmental crisis.
Download or read book Perspectives on the Marine Animal Forests of the World written by Sergio Rossi and published by Springer Nature. This book was released on 2021-02-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.

Download or read book Constructed Ecologies written by Margaret Grose and published by Routledge. This book was released on 2017-03-16 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, designers are shifting the practice of landscape architecture towards the need for a more complex understanding of ecological science. Constructed Ecologies presents ecology as critical theory for design, and provides major ideas for design that are supported with solid and imaginative science. In the questioning narrative of Constructed Ecologies, the author discards many old and tired theories in landscape architecture. With detailed documentation, she casts off the savannah theory, critiques the search for universals, reveals the needed role of designers in large-scale agriculture, abandons the overlay technique of McHarg, and introduces the ecological and urban health urgency of public night lighting. Margaret Grose presents wide-ranging new approaches and shows the importance of learning from science for design, of going beyond assumptions, of working in multiple rather than single issues, of disrupting linear design thinking, and of dealing with data. This book is written with a clear voice by an ecologist and landscape architect who has led design students into loving ecological science for the support it gives design.
Download or read book Human Activities and the Tropical Rainforest written by Bernard K. Maloney and published by Springer Science & Business Media. This book was released on 1998 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself. Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has been to suggest that rainforest, because of its complexity and the complexity of people-rainforest relationships throughout time, deserves study from a broad perspective. This book poses more questions than answers about the rainforest and it is hoped that it will encourage readers to think about the rainforest in a wider way than hitherto. This book is aimed at geographers (physical and human), social anthropologists, archaeologists, pedologists, foresters and tropical botanists and will be of value to graduates of various disciplines setting out to research the rainforest.
Download or read book Lizards of the World written by Gordon H. Rodda and published by JHU Press. This book was released on 2020-09-01 with total page 828 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first, definitive reference on the natural history and ecology of every one of the known 6500+ species of lizards, spanning the entire globe. Our planet is literally crawling with lizards. More than 6500 species are known to science, and new species are being discovered annually. In this monumental work, eminent researcher Gordon Rodda has created the first compilation of the natural histories of all the world's lizards and amphisbaenians, as well as the Tuatara. Although other books have attempted to survey the scope of adaptations present in the world's lizards, only Rodda has been able to quantify and summarize all species or higher taxa. Analyzing the relationships among traits such as morphologic characteristics, reproductive strategies, and food sources, Rodda uncovers novel insights into reptile ecology. Identifying 14 recurring character syndromes across all the world's lizards, he proposes a new lens for categorization. He also touches on • common names • geographic range • length • mass • age • maturation • differences between the sexes • nominal variables, including diel activity cycle and foraging mode • home range • predator avoidance tactics • thermal biology • social spacing • climate envelope • habitat and microhabitat • reproduction • parental care • diet • population density • conservation status • ecological business models Rodda's alphabetical taxon accounts provide an instantly retrievable sketch of every species, genus, and family. Outlining more than 1500 statistically significant associations extracted from a data matrix composed of more than 300 conditions tabulated—to the extent known—for all 6528 species of lizards, Lizards of the World will be the go-to source for the next generation of reptile ecologists, as well as herpetology students and serious herpetoculturists.
Download or read book Retreat written by Ethel Baraona Pohl and published by dpr-barcelona. This book was released on 2020-07-31 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retreat is a lexicon, or inventory of language, to describe the action of withdrawal from civic life. By creating a spatial approach to the language of “escape”, the publication attempts to widen the definitions of familiar terms such as safety, surveillance, and self-reliance. The lexicon draws attention to current global events, such as the thread of epidemic disease, climate catastrophe, the militarization of public space and the impact of mass surveillance on daily life, specifically the emotional and social impact of the presence of unknown and potentially life threatening elements. The editorial approach for the lexicon is to investigate the notion and practices of retreat, its strategies and imaginaries, through others’ words as they inform contemporary spatial paradigms. A wide variety of source types (from blogs to Wikipedia to academic texts) and media (photographs, films,books, objects) and forms of literary genres are mobilized to create a portrait of retreat that describes not only militarized zones but dreams and anxieties of individuals across the globe, helping us better understand how humans might negotiate civil and human rights and freedoms within civic society at large.

Download or read book Mesophotic Coral Ecosystems written by Yossi Loya and published by Springer. This book was released on 2019-05-22 with total page 1003 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.
