André Desrochers
André Desrochers is a Quebec scientist with expertise in ornithology and ecology. As of 2015, he has worked for almost thirty years in these research areas. Since the mid-1990s, he also worked to promote environmental conservation through various organizations. Academic background After studies in biology at Laval University, Quebec and in zoology at the University of Alberta in Canada, he obtained a doctorate in zoology at the University of Cambridge in the UK. After three post-doctoral internships – in zoology at the University of Cambridge for the first (1991), the other two at Laval University, including one in the biology department (1992–1993) and the other in the plant sciences department (1993–1994) – he was a visiting scholar at the department of ecology and systematic of the University of Helsinki, Finland (2001–2002) and at the Cornell Lab of Ornithology in the United States (2008–2009). He is a fellow of the American Ornithologists' Union. Professio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithology
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre For Forest Research
The Centre for Forest Research (Centre d'Étude de la Forêt) is a group of researchers in eastern Canada interested in forest ecology and forest management. It is a new network created with the amalgamation of two research centres that had been operating in the province of Quebec, Canada. The present structure is built around 46 scientists from eight universities in the province. Main research fields are ecophysiology, genetics, silviculture, entomology, ornithology, mycology and ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi .... The research will link these disciplines with the development of innovative alternatives regarding the management of forested lands in the province.

Society Of Canadian Ornithologists
The Society of Canadian Ornithologists, or Société des Ornithologistes du Canada, is an ornithological non-profit organization serving Canada’s ornithological community. It was founded in 1983, and is a member of the Ornithological Council. The goals of the Society are to encourage and support research towards the understanding and conservation of Canadian birds, serve as a professional society for both amateur and professional Canadian ornithologists, represent Canadian ornithologists within professional ornithological societies, publish information about Canadian birds, and recognise excellence in research, conservation and mentorship in the Canadian ornithological community. Publications and awards The Society produces the journal ''Avian Conservation and Ecology'' (French: ''Écologie et Conservation des Oiseaux''), which is published jointly with Birds Canada, as well as a newsletter, ''Picoides''. It makes two annual awards, the Doris Huestis Speirs Award, which is gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peatland Bird Ecology
A mire, peatland, or quagmire is a wetland area dominated by living peat-forming plants. Mires arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia. All types of mires share the common characteristic of being saturated with water, at least seasonally with actively forming peat, while having their own ecosystem. Like coral reefs, mires are unusual landforms that derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning. A quagmire is a floating (quaking) mire, bog, or any peatland being in a stage of hydrosere or hydrarch (hydroseral) succession, resulting in pond-filling yields underfoot. Ombrotrophic types of quagmire may be called quaking bog (quivering bog). Minerotrophic types can be named with the term quagfen. There are four types of mire: bog, fen, marsh and swamp. A bog is a mire that, due to its location relative to the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Landscape Ecology
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winter s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
