Book Description
The number of currently known, described and accepted plant species is ca 374,000, of which approximately 295,00 (79%) are angiosperms. Almost 90% of this huge number of flowering plants is pollinated by animals (mostly insects) via nectar-mediated interactions. Notably, three-fourths of the leading global crop plants produce nectar and are animal pollinated, which is estimated to account for one-third of human food resources. Nectar can also be produced on tissues outside of flowers, by so-called extrafloral nectaries, and commonly mediate interactions with ‘body-guard’ ants and other pugnacious insects that defend the plant from herbivores. Extrafloral nectar is present in almost 4,000 plant species, a majority of them in the angiosperms. This brief summary on the occurrence of nectar in the plant kingdom is just to highlight that nectar has a fundamental role in two basal functions that allow the maintenance of our ecosystems: sexual plant reproduction and protection of plants from herbivory. Despite playing essential ecological and evolutionary functions, our current knowledge about nectar is largely incomplete; however, new research directions and perspectives on nectaries and nectars have arisen in recent years. In the last two decades, there were only a few ‘moments’ in which nectar was the main character in international meetings or in published books. In 2002, the first (and only) international meeting “Nectar and nectary: from biology to biotechnology” dedicated exclusively to nectar and nectaries was held in Italy (Montalcino, Siena) and in 2003 the proceedings were published in a special volume of Plant Systematics and Evolution (238, issue 1-4). In 2007, the book Nectar and Nectaries was published (Springer) with most of the contributions provided by authors that attended the meeting in Italy. Another book dedicated to nectar was published in 2015 (Nectar: Production, Chemical Composition and Benefits to Animals and Plants, Nova Science Publishers) covering aspects mainly related to nectar chemical composition and plant-pollinator interactions. Similarly, symposia focused on nectar have been organized within the International Botanical Congress in 2011 and 2017. Considering that the last few years has yielded essential developments in the understanding of nectar biology, we thought now is the moment to further stimulate research on this important topic. This aim has been met through 18 papers published in our Research Topic New Perspectives on the Biology of Nectaries and Nectars, with subjects spanning evolution and ecology to nectar chemistry and nectary structure.

Book Description
Crop losses by pests (insects, diseases and weeds) are as old as plant themselves but as agriculture are intensified and cropping patterns including the cultivation of high yielding varieties and hybrids are changing over time the impact of the pests becoming increasingly important. Approximately less than 1000 insect species (roughly 600-800 species), 1500 -2000 plant species, numerous fungal, bacterial and nematode species as well as viruses are considered serious pests in agriculture. If these pests were not properly controlled, crop yields and their quality would drop, considerably. In addition production costs as well as food and fiber prices are increased. The current book is going to put Plant Protection approaches in perspective.

Book Description
When migrating birds and other creatures move along a path of plant communities in bloom, they follow what has come to be known as a nectar trail. Should any of these plants be eliminated from the sequence—whether through habitat destruction, pests, or even aberrant weather—the movement of these pollinators may be interrupted and their very survival threatened. In recent efforts by ecologists and activists to envision a continental-scale network of protected areas connected by wildlife corridors, the peculiar roles of migratory pollinators which travel the entire length of this network cannot be underestimated in shaping the ultimate conservation design. This book, a unique work of comparative zoogeography and conservation biology, is the first to bring together studies of these important migratory pollinators and of what we must do to conserve them. It considers the similarities and differences among the behavior and habitat requirements of several species of migratory pollinators and seed dispersers in the West—primarily rufous hummingbirds, white-winged doves, lesser long-nosed bats, and monarch butterflies. It examines the population dynamics of these four species in flyways that extend from the Pacific Ocean to the continental backbone of the Sierra Madre Oriental and Rocky Mountains, and it investigates their foraging and roosting behaviors as they journey from the Tropic of Cancer in western Mexico into the deserts, grasslands, and thornscrub of the U.S.-Mexico borderlands. The four pollinators whose journeys are traced here differ dramatically from one another in foraging strategies and stopover fidelities, but all challenge many of the truisms that have emerged regarding the status of migratory species in general. The rufous hummingbird makes the longest known avian migration in relation to body size and is a key to identifying nectar corridors running through northwestern Mexico to the United States. And there is new evidence to challenge the long-supposed separation of eastern and western monarch butterfly populations by the Rocky Mountains as these insects migrate. Conserving Migratory Pollinators and Nectar Corridors in Western North America demonstrates new efforts to understand migratory species and to determine whether their densities, survival rates, and health are changing in response to changes in the distribution and abundance of nectar plants found within their ranges. Representing collaborative efforts that bridge field ecology and conservation biology in both theory and practice, it is dedicated to safeguarding dynamic interactions among plants and pollinators that are only now being identified.

Book Description
This volume is a collection of essays by leading scholars who treat various aspects of the Hindu thinker Śaṃkara (ca. 700 CE) and his system of Advaita Vedānta. Topics include the contemporary relevance of Śaṃkara for inter-religious dialogue and human rights as well as revised assessments of Śaṃkara’s understanding of divine grace, the role of the gods, Buddhism, Śaṃkara’s relation to later Advaita, and the unity of the Self. The introductory essay of this commemoration volume assesses the place and value of Richard De Smet’s work in the context of twentieth century Śaṃkara scholarship. The contributors break new scholarly ground and offer fresh perspectives on Śaṃkara and Advaita Vedānta and help reassess traditional understandings of this great master of non-duality.

Book Description
In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.
