Histoire du Jardin botanique de Montréal; évocation des personnes qui y travaillèrent, entre autres, le Frère Marie-Victorin et Pierre Bourque.
Le débat sur les institutions de haut savoir au Québec remonte aussi loin que la Conquête et n'a jamais cessé, aussi bien chez les anglophones que chez les francophones. Avec la fondation des universités McGill en 1821, et Laval en 1852, suivies par d'autres établissements d'enseignement supérieur, les débats cessent d'être purement théoriques. L'idée d'université évolue désormais avec sa mise en œuvre. Ce sont souvent ceux qui lui consacrent leur vie qui sentent le besoin de faire le point sur ce qu'est devenu l'enseignement supérieur : William Dawson, Édouard Montpetit, Marie-Victorin, F. Cyril James, Guy Rocher. Mais la place centrale de l'université dans la société en...
This text provides an important overview of the contributions of edible insects to ecological sustainability, livelihoods, nutrition and health, food culture and food systems around the world. While insect farming for both food and feed is rapidly increasing in popularity around the world, the role that wild insect species have played in the lives and societies of millions of people worldwide cannot be ignored. In order to represent this diversity, this work draws upon research conducted in a wide range of geographical locations and features a variety of different insect species. Edible insects in Sustainable Food Systems comprehensively covers the basic principles of entomology and population dynamics; edible insects and culture; nutrition and health; gastronomy; insects as animal feed; factors influencing preferences and acceptability of insects; environmental impacts and conservation; considerations for insect farming and policy and legislation. The book contains practical information for researchers, NGOs and international organizations, decision-makers, entrepreneurs and students.

Haploid plants have the gametophytic number of chromosomes. They are of great importance, especially in studies on the induction of muta tions and also for the production of homozygous plants, they are needed in large numbers. The conventional methods employed by plant breeders for their production are cumbersome, time-consuming, laborious and rather inefficient. Sometimes it may take years to produce a pure line. However, with the introduction of in vitro techniques, especially anther culture for the induction of androgenesis, it has become increasingly evi dent that these methods considerably accelerate the production of haploids for plant breeding programs. During the last decade, in vitr...
Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.
