Forests and vegetation emit biogenic volatile organic compounds (BVOCs) into the atmosphere which, once oxidized, can partition into the particle phase, forming secondary organic aerosols (SOAs). This thesis reports on a unique and comprehensive analysis of the impact of BVOC emissions on atmospheric aerosols and climate. A state-of-the-art global aerosol microphysics model is used to make the first detailed assessment of the impact of BVOC emissions on aerosol microphysical properties, improving our understanding of the role of these emissions in affecting the Earth's climate. The thesis also reports on the implications for the climate impact of forests. Accounting for the climate impacts of SOAs, taken together with the carbon cycle and surface albedo effects that have been studied in previous work, increases the total warming effect of global deforestation by roughly 20%.

Gregor Johann Mendel continues to fascinate the general public as well as scholars, the former for his life and the latter for his achievements. "Solitude of a Humble Genius" is a two-volume biography presenting Mendel in the context of the history of biology and philosophy, and in the context of the setting in which he lived and worked. In this first volume the authors set the stage for a new interpretation of Mendel s achievements and personality. The period of Mendel s life covered by this volume is critical to understanding why he saw what other biologists, including Charles Darwin, for example, didn t. In searching for clues to Mendel s thinking, the authors discuss at length the origin of his genes; the history of the region of his birth; they also spend a day and then the four seasons of the year with his family; and finally they examine the schooling he received, as well as the cultural and political influences he was exposed to.

An indispensible part of the work is Norman Klein s artwork. In this first volume alone, it comprises nearly 80 original drawings and includes cartoons that enliven the narration, scenes from Mendel s life, portraits, and plans and drawings of the cities and buildings in which he lived, studied, and worked."

This is a synthesis of several studies on fluxes of carbon, water and energy conducted in a range of European forests encompassing different climates, soils and biomes. The volume covers methodological issues, particularly the eddy covariance technique describing its limitations and practical use. Further, major insights in ecosystem processes gained through investigations in evergreen coniferous, mediterranean and broad-leaved forests are presented. In an integrated effort, atmospheric physicists, ecologists, ecosystem modellers, and remote sensing scientists elucidate the impact of terrestrial ecosystems on the global biogeochemistry of the earth.

This new book shows the work done by researchers dedicated to the study of different mycorrhizas types, the fungal species associated and their distribution influenced by geographical and environmental factors among the different South American biogeographic regions. The exclusive biotic and abiotic characteristics delimit natural ecosystems with uniques biological communities, where mycorrhizologists have investigated plant symbioses in those ecosystems for decades, providing data from Venezuelan Great Savannah, Andes, Puna, Chaco, Caatinga, Monte, Atlantic Forest, Marginal Forest, Cerrado, Patagonia, Yungas, Rainforest, Andean-Patagonian Forests, and Antarctic section. In these environments, different mycorrhizal associations (arbuscular / ericoid / orchidoid / ectomycorrhizal / mycoheterotrophic) are present in herbaceous plants, shrubs, and trees. Mycorrhizal associations were studied from different researching points of view (biodiversity, biological invasions, biotic / abiotic disturbances, altitudinal variations, seasonal changes, land uses). The aim of this Book is to compile research on mycorrhizal fungi and their associations in environments of South America, throughout the synthesis of information from natural and anthropogenic related environments. The book focuses in different bioregions of South America from tropical areas to the southern cone, and it will be useful to those who work on plant-fungal interactions in different vegetation types and in agricultural lands from South America and worldwide.

Herbicide resistance has become an important constraint on modern agricultural practices. An alarming increase in weed biotypes that are resistant to herbicides has also been reported. Opportunity exists for a novel weed management technology, which is also compatible with no-till agricultural practices. Microwave heating can kill both emerged weed plants and weed seeds in the soil. When the intensity of the microwave fields is moderate, plants, which have already emerged, are susceptible to microwave treatment. If the microwave field is intense enough, very rapid volumetric heating and some thermal runaway in the plant structures cause micro-steam explosions in the plant cells, which rupture the plant structures, leading to death. Soil treatment requires significantly more energy; however, there are secondary benefits for crops growing in microwave treated soil. These include: significant reduction of the dormant weed seed bank; significant reduction of nematode populations; significant reduction of fungal populations; better availability of indigenous nitrogen for the plants; more rapid humification; and significant increases in crop growth and yield. Microwave weed management and soil treatment is not restricted by weather conditions; therefore, the technology may offer some timeliness and environmental benefits, which are yet to be quantified in a cropping system.

Plants come in myriads of shapes and colors, and the beauty of plants has fascinated mankind for thousands of years. Long before Mendel discovered the laws of heritab- ity and Darwin developed his theory on evolution, the affection for ornamental plants led people to select alleles that establish novel plant forms. Today, plant developmental biology tries to discover the mechanisms that control the establishment of specialized cell types, tissues, and organs from the fertilized egg during a plant's life. Although the underlying processes of cell proliferation and differentiation are similar in plants and a- mals, plants are different because their development is usually open, and its outcome is not the faithful repetition of a general plan but is strongly in?uenced by environm- tal conditions. In the last few decades, plant developmental biology has pinpointed a large number of developmental regulators and their interactions and the mechanisms that govern plant development start to emerge. In part, this progress was enabled by the advance of powerful molecular tools for a few model species, most importantly Arabidopsis. This volume of the Methods in Molecular Biology series provides a collection of protocols for many of the common experimental approaches in plant developmental bi- ogy. All chapters are written in the same format as that used in the Methods in Molecular TM Biology series. Each chapter opens with a description of the basic theory behind the method being described.

With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. This latest volume includes reviews on plant physiology, biochemistry, genetics and genomics, forests, and ecosystems.

This volume focuses on the outstanding contributions made by botany and the mathematical sciences to the genesis and development of early modern garden art and garden culture. The many facets of the mathematical sciences and botany point to the increasingly "scientific" approach that was being adopted in and applied to garden art and garden culture in the early modern period. This development was deeply embedded in the philosophical, religious, political, cultural and social contexts, running parallel to the beginning of processes of scientization so characteristic for modern European history. This volume strikingly shows how these various developments are intertwined in gardens for various purposes.

Plant molecular biology has produced an ever-increasing flood of data about genes and genomes. Evolutionary biology and systematics provides the context for synthesizing this information. This book brings together contributions from evolutionary biologists, systematists, developmental geneticists, biochemists, and others working on diverse aspects of plant biology whose work touches to varying degrees on plant molecular evolution. The book is organized in three parts, the first of which introduces broad topics in evolutionary biology and summarizes advances in plant molecular phylogenetics, with emphasis on model plant systems. The second segment presents a series of case studies of gene family evolution, while the third gives overviews of the evolution of important plant processes such as disease resistance, nodulation, hybridization, transposable elements and genome evolution, and polyploidy.

The volume is intended as an introduction to the physical principles governing the main processes that occur in photosynthesis, with emphasis on the light reactions and electron transport chain. A unique feature of the photosynthetic apparatus is the fact that the molecular structures are known in detail for essentially all of its major components. The availability of this data has allowed their functions to be probed at a very fundamental level to discover the design principles that have guided evolution. Other volumes on photosynthesis have tended to focus on single components or on a specific set of biophysical techniques, and the authors' goal is to provide new researchers with an introduction to the overall field of photosynthesis. The book is divided into sections, each dealing with one of the main physical processes in photosynthetic energy conversion. Each section has several chapters each describing the role that a basic physical property, such as charge or spin, plays in governing the process being discussed. The chapters proceed in an orderly fashion from a quantum mechanical description of early processes on an ultrafast timescale to a classical treatment of electron transfer and catalysis on a biochemical timescale culminating in evolutionary principles on a geological timescale.

In the 1970s, Rolla and Alice Tryon of Harvard organized an annual fern conference at Harvard Forest every spring. The mission of the conference was to bring together researchers from across a broad spectrum of biology whose common link was that they either studied ferns per se or utilized ferns in their experiments. Talks ranged from classical pteridological subjects such as taxonomy, paleobotany and morp- logy, to experimental areas such as ecology, physiology, development, genetics, and biochemistry. For the participants, of whom I was lucky to be one, it was an int- lectually exhilarating experience. We all learned new things, and the cross fertili- tion of different subjects and research approaches led to new ideas and a better understanding of ferns as organisms. The present volume, Working with Ferns: Issues and Applications, edited by Helena Fernandez, Ashwani Kumar and Maria Angeles Revilla, carries the Harvard Forest Fern Conference philosophy into the twenty-first century. The editors have assembled a truly remarkable array of contributions dealing with fern biology. Starting with researches utilizing Ceratopteris, a fern whose speedy life cycle I discovered during my doctoral research at the Royal Botanic Gardens, Kew more than 40 years ago, and ending with a study of Pteridium aq- linum, a cosmopolitan species taxonomically revised by Professor Rolla Tryon, the papers in Working with Ferns: Issues and Applications offer a look at what is new in pteridology.
