recruitment of adult plants in entire communities, and all of them focus on changes in total densities of A central issue of plant ecology is the understanding individuals and do not refer to changes in community of the relative role of different life history stages in structure (Moles and Drake 1999; Rebollo et al. successful plant recruitment. The consecutive stages 2001; Goldberg et al. 2001). This ?eld of research of seed, seedling, and adult are related to each other has hardly been explored empirically, and we think it in a complex way that largely depends on species and may reveal interesting mechanisms for the regulation the in?uence of physical and biological factors of individual density and species diversity in plant (Goldberg et al. 2001), for example, irrigation and communities. At the functional group level (which grazing. As a result of relationships between these sorts species according to common features), we stages, the consequences of an ecological factor expect differences depending on growth form depend on the way that its effects propagate onto the (grasses versus forbs) and depending on seed mass following stage of the recruitment process. As far as (differences between small-seeded, medium-seeded, we know, there are no published studies that have and large-seeded species). Some authors (Goldberg addressed this subject. et al. 2001; Rebollo et al. 2001) studying annual In this article, we characterize the relationships plant communities have found greater seedling between the three plant developmental stages.

The most comprehensive existing volume of multidisciplinary research by top ecologists on the herbaceous layer of forests.

This open access book presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time. The research, focusing on the Ooyamazawa riparian forest, one of the remaining old-growth forests in Japan, has yielded a number of interesting outcomes. First, it shows that large-scale disturbances afford various trees opportunities for regeneration and are thus the driving force for the coexistence of canopy trees in riparian forests. Second, it identifies changes in reproductive patterns, highlighting that seed production has in fact quantitatively increased over the past two decades. Third, it describes the decline in forest floor vegetation caused by deer grazing and reveals how this decline has affected bird and insect populations. The book illustrates the interconnectedness of phenomena within an ecosystem and the resultant potential for cascade effects and also stresses the need for long-term ecological studies of climate change impacts on forests. It will be of interest to both professionals and academics in the field of forest science.

Floodplains are ecosystems which are driven by periodic inundation and oscillation between terrestrial and aquatic phases. An understanding of such pulsing systems is only possible by studying both phases and linking the results into an integrated overview. This book presents the results of a 15-year study of the structure and function of one of the largest tropical floodplains, the Amazon River floodplain. It covers qualitative aspects, e.g., adaptations of aquatic and terrestrial organisms to the flood pulse as well as quantitative aspects, e.g., studies of biomass, primary production, decomposition, and nutrient cycles. The authors interpret their findings and the most important data from other studies under an integrating scientific concept, the Flood Pulse Concept.

Generations of plant scientists have been fascinated by alpine plant lifean ecosystem that experiences dramatic climatic gradients over a very short distance. This comprehensive book examines a wide range of topics including alpine climate and soils, plant distribution and the treeline phenomenon, plant stress and development, global change at high elevation, and the human impact on alpine vegetation. Geographically, the book covers all parts of the world including the tropics.

This guide to common and unique plants found in forests of the Southeast thoroughly covers 330 species of forbs (herbaceous plants), grasses, vines, and shrubs, with a special emphasis on the plants role in wildlife sustenance. Packed with detailed color photographs, the book is a must-have for forest landowners, game and wildlife managers, biologists, outdoors enthusiasts, students--anyone with an interest in the intricate and often unexpected interrelationships between the flora and fauna of our regions forests. Features: Descriptions of native and nonnative (exotic or invasive) plants, including 330 species of forbs, in 180 genera: grasses, sedges, and rushes; woody vines and semiwoody plants; shrubs; palms and yucca; cane; cactus; ferns; and ground lichen 650 color photos Map of physiographic provinces 56 simple black-and-white drawings of flower parts, flower types, and inflorescences, leaf arrangements, leaf divisions, shapes, and margins, and parts of a grass plant Glossary Index of genera by family, index by wildlife species, and index of scientific and common names
