Book Description
This book presents current knowledge of seed fate in both natural and human-disturbed landscapes, from various regions of the world. Habitats considered range from mountain and arid deserts in the temperate zone, to savanna and lowland rainforests in tropical regions of the world. Particular attention is paid to plant diversity conservation when seed removal is affected by factors such as hunting, habitat fragmentation or intensive logging. Contributors include leading scientists involved in research on seed ecology and on animal-plant relationships from the perspective of both primary and secondary seed dispersal, and predation.

Book Description
Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel.

Book Description
This book is based on the ICAR syllabus of Seed Science and Technology. It comprises of two major parts: 1. Seed Science and Technology and 2. Advances in Seed Science and Technology. The pat 1 consists of eight units of Seed Science and Technology like seed biology, seed production, seed processing, seed quality control, seed storage, seed health, seed industry development and marketing and protection of plant varieties. The part 2 involves the advances in Seed Science and Technology on seed physiology and biochemistry. In this, the units such as seed development and maturation, seed dormancy and germination, and seed deterioration are included.

Book Description
The Guiana Shield is an ancient geological formation located in the northern part of South America, covering an area of one million square kilometres. Despite its hostile environment, it is home to many unusual and highly specialized plants and animals, which constitute a rich area of biodiversity. Chapters in this book include hydrology, nutrient cycling, forest phenology, insect-plant interactions, forest microclimate, plant distributions, forest dynamics and conservation and management of flora and fauna. It provides a comprehensive and detailed review of the ecology, biology and natural history of the forests of the area.

Book Description
Was verstanden Stoiker unter einer polis und Staatlichkeit? Was passiert, wenn ihre Ideen unter wechselnden historischen Bedingungen gelebt und neu gedacht werden? The Stoics and the State verfolgt diese Fragen mit detaillierter, philologischer Quellenkritik, präziser Konzeptanalyse sowie weit ausholender thematischer und diachronischer Kontextualisierung. Der systematische Teil behandelt Definitionen, Aspekte der Staatlichkeit (Staatsgebiet, Institutionen, Volk und Staatsidee) und das für den stoischen Staat konstitutive Gemeinsame Gesetz. Die diachronische Darstellung von Zeno bis Marcus Aurelius zeigt die Anwendung der Theorie auf real existierende Gemeinwesen: ihre Bewertung, ihre Entstehung und die politische Praxis. Beispiele moderner Rezeption von Justus Lipsius bis Martha C. Nussbaum verdeutlichen die Eigenheiten der stoischen Staatstheorie, nicht zuletzt ihre Grundlegung in einem Menschbild, das unsere Natur nicht nur als politisch sondern als sozial und wohltätig begreift.

Book Description
Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination. This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes. Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy A world biogeographical perspective on seed dormancy and germination Ecophysiology of seeds with each type of dormancy Critical evaluation of methodology used in soil seed bank studies Germination ecology of plants with specialized habitat and life cycle types Genetic and maternal preconditioning effects on seed dormancy and germination Guidelines for doing ecologically-meaningful germination studies

Book Description
The common idea for many people is that forests are just a collection of trees. However, they are much more than that. They are a complex, functional system of interacting and often interdependent biological, physical, and chemical components, the biological part of which has evolved to perpetuate itself. This complexity produces combinations of climate, soils, trees and plant species unique to each site, resulting in hundreds of different forest types around the world. Logically, trees are an important component for the research in forest ecosystems, but the wide variety of other life forms and abiotic components in most forests means that other elements, such as wildlife or soil nutrients, should also be the focal point in ecological studies and management plans to be carried out in forest ecosystems. In this book, the readers can find the latest research related to forest ecosystems but with a different twist. The research described here is not just on trees and is focused on the other components, structures and functions that are usually overshadowed by the focus on trees, but are equally important to maintain the diversity, function and services provided by forests. The first section of this book explores the structure and biodiversity of forest ecosystems, whereas the second section reviews the research done on ecosystem structure and functioning. The third and last section explores the issues related to forest management as an ecosystem-level activity, all of them from the perspective of the "other" parts of a forest.
