Download or read book Wonders of the Plant Kingdom written by Wolfgang Stuppy and published by University of Chicago Press. This book was released on 2015-02-23 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to the obvious complexity of animals, plants at a glance seem relatively simple in form. But that simplicity is deceptive: the plants around us are the result of millennia of incredible evolutionary adaptations that have allowed them to survive, and thrive, under wildly changing conditions and in remarkably specific ecological niches. Much of this innovation, however, is invisible to the naked eye. With Wonders of the Plant Kingdom, the naked eye gets an unforgettable boost. A stunning collaboration between science and art, this gorgeous book presents hundreds of images of plants taken with a scanning electron microscope and hand-colored by artist Rob Kesseler to reveal the awe-inspiring adaptations all around us. The surface of a peach—with its hairs, or trichomes, and sunken stomata, or breathing pores—emerges from these pages in microscopic detail. The dust-like seeds of the smallest cactus species in the world, the Blossfeldia liliputana—which measures just twelve millimeters fully grown—explode here with form, color, and character, while the flower bud of a kaffir lime, cross-sectioned, reveals the complex of a flower bud with the all-important pistil in the center. Accompanying these extraordinary images are up-to-date explanations of the myriad ways that these plants have ensured their own survival—and, by proxy, our own. Gardeners and science buffs alike will marvel at this wholly new perspective on the world of plant diversity.

Download or read book Biodiversity and Ecosystem Processes in Tropical Forests written by Gordon H. Orians and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although biologists have directed much attention to estimating the extent and causes of species losses, the consequences for ecosystem functioning have been little studied. This book examines the impact of biodiversity on ecosystem processes in tropical forests - one of the most species-rich and at the same time most endangered ecosystems on earth. It covers the relationships between biodiversity and primary production, secondary production, biogeochemical cycles, soil processes, plant life forms, responses to disturbance, and resistance to invasion. The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes.

Download or read book Frugivores and seed dispersal written by Alejandro Estrada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of plants, ranging in size from forest floor herbs to giant canopy trees, rely on animals to disperse their seeds. Typical values of the proportion of tropical vascular plants that produce fleshy fruits and have animal-dispersed seeds range from 50-90%, depending on habitat. In this section, the authors discuss this mutualism from the plant's perspective. Herrera begins by challenging the notion that plant traits traditionally interpreted as being the product of fruit-frugivore coevolution really are the outcome of a response-counter-response kind of evolutionary process. He uses examples of congeneric plants living in very different biotic and abiotic environments and whose fossilizable characteristics have not changed over long periods of time to argue that there exists little or no basis for assuming that gradualistic change and environmental tracking characterizes the interactions between plants and their vertebrate seed dispersers. A common theme that runs through the papers by Herrera, Denslow et at. , and Stiles and White is the importance of the 'fruiting environment' (i. e. the spatial relationships of conspecific and non-conspecific fruiting plants) on rates of fruit removal and patterns of seed rain. Herrera and Denslow et at. point out that this environment is largely outside the control of individual plant species and, as a result, closely coevolved interactions between vertebrates and plants are unlikely to evolve.
Download or read book Ecology of Soil Seed Banks written by Mary Allessio Leck and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.

Download or read book Ocean Currents written by Robert Marsh and published by Elsevier. This book was released on 2021-06-30 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean Currents: Physical Drivers in a Changing World opens with a general introduction to the character, measurement, and simulation of ocean currents, leading to a physical and dynamical framework for understanding the wide variety of flows encountered in the oceans. The book comprises chapters covering distinct aspects of contrasting ocean currents: broad and slow, deep and shallow, narrow and swift, large scale and small scale, low latitudes and high latitudes, and moving in horizontal and vertical planes. Through this approach the authors cover a wide range of applications, from local to global, with considerable geographical context. Provides analyses of ocean observations and numerical model simulations, highlighting the pathways and drift associated with ocean currents, around the World Ocean, linked to online exercises for instructors and students that extend this perspective Presents applications to natural phenomena, showing how ocean currents shape marine ecosystems, helping researchers understand the distribution and adaptation of life in the oceans Addresses societal challenges, specifically how ocean currents disperse pollutants (e.g. plastic) from coastal sources and how the global ocean circulation is central to our changing climate, helping students and researchers develop an interdisciplinary approach to global environmental change
