This book is a synthesis of twenty years of work under the Loire Grandeur Nature Plan. It describes the current body of knowledge on the functioning of the fluvial-estuary Loire River system, the effects of human activities and efforts made to maintain a lasting balance.
This educational work explains the formation and functions of wood in the tree and addresses anatomy as an identification tool. Numerous illustrations complete the precise description of cell and parietal structures of coniferous and deciduous woody species. The examples chosen correspond above all to the French forest species but the bases of the anatomy of wood are the same for all wood anywhere in the world.
Compensatory measures have in recent years become a major management tool in preserving the biodiversity. They are increasingly used in the new environmental regulations. This concept of environmental compensation raises many issues of interest to ecologists, geographers, economists and lawyers alike.
What are its socio-economic challenges (nourish the planet, protect the environment, adapt to climate change, organise the seed industry)? What tools and methods are used? How are the main traits selected and improved? The work answers these questions and ends by assessing what plant breeding has brought to farmers, consumers, the industry and society.
Reproduction has been researched thoroughly and enriched with new tools for exploring living creatures that have played havoc with our knowledge of mechanisms and renewed the concepts. Over one hundred renowned French and international specialists have contributed to this reference work that summarises current knowledge on reproduction and its applications in animals and humans.
This book offers a multi-disciplinary, systemic state of the art on the influence of urban plants on seven sustainable development challenges: microclimatology, controlling energy, hydrology, ambiences, air quality, carbon footprint and biodiversity. Each challenge is assessed based on experimental and digital techniques applied and the outcome of various planting arrangements found in towns.
Ecological engineering surging in popularity and is sparking increasing interest in terrestrial and aquatic environment management. Irstea scientists joined by ten researchers and practicians from other institutes have been wondering about the definition of ecological engineering envisaged as a design and action domain where mobilisation of the living is essential in order to restore, conserve or manage natural environments or those impacted by human activities.
Marine plankton and the pesticides used on land can meet in coastal waters. Even when highly diluted, the treatment products and their residues conveyed by the runoff water sooner or later enter estuary and then coastal waters. The result is metabolic disturbances, breeding of tolerant species, changes in natural balances and even alteration of ecosystems.
Redox (or oxidation-reduction) reactions are chemical reactions during which electrons are transferred. This work explains the basic concepts of redox chemistry and the significance thereof in microbial ecology. This field of biology has experienced tremendous growth in the last few years. Its basic or applied developments cover nearly all topics in the study of life: the sustainability of biosystems, animal and human health, the contamination of the biosphere subject to human activities.
A number of terrestrial green plants live in intimate, mutualist association with root-based fungi as mixed organs called mycorrhizae. This work is the first in-depth, exhaustive summary on the topic in French. It outlines the most recent fundamental research and its practical applications in agronomy, horticulture, forestry and protection of natural spaces.
