Sommario/riassunto

Why do species live where they live? What determines the abundance and diversity of species in a given area? What role do species play in the functioning of entire ecosystems? All of these questions share a single core concept-the ecological niche. Although the niche concept has fallen into disfavor among ecologists in recent years, Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology. Chase and Leibold define the niche as including both what an organism needs from its environment and how that organism's activities shape its environment. Drawing on the theory of consumer-resource interactions, as well as its graphical analysis, they develop a framework for understanding niches that is flexible enough



to include a variety of small- and large-scale processes, from resource competition, predation, and stress to community structure, biodiversity, and ecosystem function. Chase and Leibold's synthetic approach will interest ecologists from a wide range of subdisciplines.

Sommario/riassunto

Les routiers et mercenaires de la guerre de Cent ans (1337-1453) ont longtemps été mal vus par les historiens à cause de leur rôle ambigu lors de cette guerre. Oscillant entre emploi par les pouvoirs princiers et une autonomie quasi-totale, leur place au sein du conflit franco-anglais pose toutefois de nombreuses questions que les actes de de colloque tentent de résoudre. Les contributions de ce volule écrites par des spécialistes de l'histoire de la guerre médiévale permettent de se faire une meilleure idée du complexe phénomène routier qui a eu sans doute une place plus importante que celle qui lui fut reconnu par l'historiographie jusqu'à une période récente.
