The aim of this manual is to provide a comprehensive guide to the methods involved in collecting, preparing and screening plants for bioactive properties for manipulating key ruminal fermentation pathways and against gastrointestinal pathogens. The manual will better equip the reader with methodological approaches to initiate screening programmes to test for bioactivity in native plants and find natural alternatives to chemicals for manipulating ruminal fermentation and gut health. The manual provides isotopic and non-isotopic techniques to efficiently screen plants or plant parts for a...

The notion of Endangerment stands at the heart of a network of concepts, values and practices dealing with objects and beings considered threatened by extinction, and with the procedures aimed at preserving them. Usually animated by a sense of urgency and citizenship, identifying endangered entities involves evaluating an impending threat and opens the way for preservation strategies.

Endangerment, Biodiversity and Culture looks at some of the fundamental ways in which this process involves science, but also more than science: not only data and knowledge and institutions,...

Girling, named Environmental Journalist of the Years 2008 and 2009, has here chronicled - through the hunt for the Somali golden mole - the development of the conservation movement, the importance of diversity in the animal kingdom, including humankind within this realm, as well...

Invasive species are everywhere, from forests and prairies to mountaintops and river mouths. Their rampant nature and sheer numbers appear to overtake fragile native species and forever change the ecosystems that they depend on. Concerns that invasive species represent significant threats to global biodiversity and ecological integrity permeate conversations from schoolrooms to board rooms, and concerned citizens grapple with how to rapidly and efficiently manage their populations. These worries have culminated in an ongoing -war on invasive species, - where the arsenal is stocked with...

During the past 30 years, industrialization has fundamentally changed traditional rural life and agricultural practices in China. While the incomes of farmers have increased, serious issues have been raised concerning the environment, resource depletion, and food safety. In response, the Chinese government and Chinese scientists encouraged eco-agriculture, the practice of agroecology principles and philosophy, as a way to reduce the negative consequences of large-scale industrialized systems of farming.

Agroecology in China: Science, Practice, and Sustainable Management represents the...

How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions, and shows how their discoveries matter for our health and the health of the planet we depend upon.

One of the most important revelations about the natural world is that...

A wide range of crop genetic resources is vital for future food security. Loss of agricultural biodiversity increases the risk of relying on a limited number of staple food crops. However, many laws, such as seed laws, plant varieties protection and access and benefit-sharing laws, have direct impacts on agrobiodiversity, and their effects have been severely underestimated by policy-makers. This is of concern not only to lawyers, but also to agronomists, biologists, and social scientists, all of whom need clear guidance as to the relevance of the law to their work.
