Available in PDF, EPUB and Kindle. Book excerpt: The capabilities of four species of submersed freshwater macrophytes in mobilizing nitrogen (N), phosphorus (P), and potassium (K) from three different sediments were comparatively examined in relation to their requirements for these nutrients during a 10-week period of growth under controlled environmental conditions. With all species, N and P were readily mobilized from each of the sediments and concentrated in plant shoots at levels well above those required for growth. However, the mobilization of K from all sediments was much less effective and may have limited the growth of the species considered. Sediments represent a large and important source of N and P for rooted aquatic macrophytes, but K is probably supplied to these plants primarily from the water. (Author).

The topics range from macrophytes as fish food to macrophytes as mollusc and microbe habitat, making this of interest to aquatic ecologists as well as limnologists, ecosystem ecologists, microbial ecologists, fish biologists, and environmental managers.
Download or read book Aquatic Macrophytes Ecology Functions and Services written by Sanjeev Kumar and published by Springer Nature. This book was released on 2023-12-24 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive collection of information about the features, functions, and services of aquatic macrophytes. As primary producers, aquatic macrophytes form the basis of food webs, play a major role in highly productive aquatic ecosystems, and have a significant impact on ecosystem functions and services. Macrophytes are also known to strongly influence the micro-climate and biogeochemical processes occurring in the littoral zones of marine ecosystems and the sediment dynamics of freshwater systems. They also serve as highly effective carbon sinks and play an important role in carbon sequestration. This book deals with various aspects of aquatic macrophytes, including nutrient recycling, biogeochemical processes, biomass production, wetland ecosystems, water resource management, carbon sequestration, environmental clean-up, and bioenergy production. Additionally, it presents the current status of aquatic macrophytes and discusses the impact of climate change on these plants. The book also highlights the major challenges associated with harnessing the benefits provided by aquatic macrophytes as ecosystem services. The book holds value and relevance for academicians and scientists working in the related domain. Additionally, it will serve as a valuable resource for students and researchers working in the field of ecology, biogeochemistry, wetland conservation, phytoremediation, elements biomonitoring, wastewater management, bioenergy production, etc.

Download or read book Shallow Lakes 95 written by Lech Kufel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.

Download or read book Habitat Structure written by S.S. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.
Download or read book The Ecophysiology of Plant Phosphorus Interactions written by Philip J. White and published by Springer Science & Business Media. This book was released on 2008-06-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently – including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant’s own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution. This latest volume in Springer’s Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interactions in natural and agricultural environments, presenting a series of critical reviews on the current status of research. In particular, the book presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability, which could be of particular relevance to developing new crop varieties with enhanced abilities to grow under P-limiting conditions. The book provides a valuable reference material for graduates and research scientists working in the field of plant-phosphorus interactions, as well as for those working in plant breeding and sustainable agricultural development.
