Piper is an economically and ecologically important genus of plant that includes a fascinating array of species for studying natural history, natural products chemistry, community ecology, and evolutionary biology. The diversification of this taxon is unique and of great importance in understanding the evolution of plants. The diversity and ecological relevance of this genus makes it an obvious candidate for ecological and evolutionary studies, but surprisingly, most research on Piper spp. to-date has focused on the more economically important plants P. nigrum (black pepper), P. methysticum (kava), and P. betle (betel leaf). While this book does address the applied techniques of studying Piper, its focus is more on Piper in its natural setting. Piper: A Model Genus for Studies of Phytochemistry, Ecology, and Evolution synthesizes existing data and provides an outline for future investigations of the chemistry, ecology, and evolution of this taxon, while examining its key themes of Piper as a model genus for ecological and evolutionary studies, the important ecological roles of Piper species in lowland wet forests, and the evolution of distinctive Piper attributes. This volume has a place in the libraries of those studying or working in the fields of ecology, evolutionary biology, natural products chemistry, invasive species biology, pharmaceutics, and ethnobotany.

Piper is the representative genus of family Piperaceae. Piper species are pan-tropical in distribution and found in both the hemispheres. As the king of all spices, black pepper, Piper nigrum, led to the global expeditions culminating in the discovery of India and the new world. Piper species have been reported to possess various pharmacological activities such as insecticidal, antibacterial, anti-inflammatory, antiplatelet, anti-hypertensive, antithyroid, antitumor activities and hepatoprotective properties. Botanical authentication of the plants of Piper species is difficult because of the morphological similarity among the species. This book describes ultra-performance liquid chromatography coupled with triple quadrupole electrospray tandem mass spectrometry in multiple reactions monitoring (MRM) mode to study the quantitative variation of thirteen bioactive markers in different plant parts of ten Piper species. Features: Collection of Ayurvedic features and scientific evidence of the most important medicinal plants of Piper species. Describes chemical signatures for identification of Piper species. Provides easy-to-use analytical procedure for quality control of Piper species and its products.

Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Black pepper (Piper nigrum) the flowering wine belongs to the family piperaceae, cultivated for its fruit, which is usually dried and used as spice and seasoning. The black pepper high variability was also noticed for yield contributing characters like runner shoot production, holding capacity, adventitious root production, lateral branch habit, spike length, number of spikes per lateral branch, fruit set, dry weight. Pharmacological, toxicological, clinical applications and general uses of pepper are bioavailability enhancement, carminative, anti-cancer, natural antioxidant, black pepper as an anti-Inflammatory drug, cholesterol lowering and Immune enhancer, anti-pyretic, anti-periodic and rubefacient, black pepper Improves digestion and promotes intestinal health, preservation of the flavour content. Four different pepper varieties in Kerala were selected based on a baseline survey. The proximate composition includes estimation of dry matter and moisture content, estimation of crude protein, estimation of crude fibre, estimation of crude ash and insoluble ash, ether extract, determination of dietary fibre, gross energy, analysis of component of different varieties of Piper nigrum were determined. The sample Munthirimunda fruit has high moisture content. The sample Chengannor leaf has high dry matter content. The sample Chenganoor leaf has high crude protein content. The sample Panniyor leaf has high crude fibre content. Ether Extract is high in sample Chenganoor leaf. The sample Munthirimunda leaf has high comparatively high Total Ash content. Gross Energy is high in sample Panniyor fruit. A wide gap in the nutritional properties of Piper nigrum varieties exist in Kerala which could be further explored.

The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

Documenting and understanding intricate ecological interactions involving insects is a central need in conservation, and the specialised and specific nature of many such associations is displayed in this book. Their importance is exemplified in a broad global overview of a major category of interactions, mutualisms, in which the interdependence of species is essential for their mutual wellbeing. The subtleties that sustain many mutualistic relationships are still poorly understood by ecologists and conservation managers alike. Examples from many parts of the world and ecological regimes demonstrate the variety of mutualisms between insect taxa, and between insects and plants, in particular, and their significance in planning and undertaking insect conservation – of both individual species and the wider contexts on which they depend. Several taxonomic groups, notably ants, lycaenid butterflies and sucking bugs, help to demonstrate the evolution and flexibility of mutualistic interactions, whilst fundamental processes such as pollination emphasise the central roles of, often, highly specific partnerships. This compilation brings together a wide range of relevant cases and contexts, with implications for practical insect conservation and increasing awareness of the roles of co-adaptations of behaviour and ecology as adjuncts to designing optimal conservation plans. The three major themes deal with the meanings and mechanisms of mutualisms, the classic mutualisms that involve insect partners, and the environmental and conservation lessons that flow from these and have potential to facilitate and improve insect conservation practice. The broader ecological perspective advances the transition from primary focus on single species toward consequently enhancing wider ecological contexts in which insect diversity can thrive.

The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants—toucans, monkeys, leaf-nosed bats, and hummingbirds to name a few—are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these “ornaments” of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.
