... the North Sea system demonstrates some characteristics of a wasp-waist ecosystem, whereby a single species dominates the intermediate trophic level. 2, record 1, English, - wasp%2Dwaist%20ecosystem
Record number: 1, Textual support number: 2 CONT
Marine ecosystems that exhibit this typical community configuration (i.e. featuring many species at the lower and upper trophic levels, but constricted to one, or at most several, dominant planktivorous forage-fish species at the crucial mid-level) have been referred to as “wasp-waist” ecosystems. 3, record 1, English, - wasp%2Dwaist%20ecosystem

Les espèces fourragères clés sont particulièrement importantes dans les écosystèmes où seulement une ou très peu d’espèces se situent au niveau trophique moyen (écosystèmes en taille de guêpe [...]). 1, record 1, French, - %C3%A9cosyst%C3%A8me%20en%20taille%20de%20gu%C3%AApe

On parle d’écosystèmes structurés en «taille de guêpe» [.. ] en raison du faible nombre d’espèces de petits pélagiques qui constituent ce niveau trophique intermédiaire. Dans ce cas, le contrôle de la chaîne trophique serait réalisé par le maillon intermédiaire, les petits pélagiques. Ainsi, cet échelon intermédiaire va jouer un rôle central dans la structure et la dynamique de l'écosystème, à la fois par le contrôle de type «top-down»(contrôle des prédateurs supérieurs sur les maillons trophiques inférieurs) sur le plancton dont il se nourrit, et par [le] contrôle «bottom-up» sur les nombreux prédateurs marins qui les consomment. 2, record 1, French, - %C3%A9cosyst%C3%A8me%20en%20taille%20de%20gu%C3%AApe

The students will investigate the links that exist within a woodland in order to explain a problem situation related to the flow of water in a forest ecosystem. The proposed activity will enable the students to gain an understanding of how the dynamic balance of an ecosystem is constantly jeopardized by interactions between human activities and the environment. 1, record 2, English, - dynamic%20balance

Les élèves mèneront une enquête sur les liens existants au sein d’un écosystème boisé afin d’expliquer une situation-problème ayant trait à la circulation de l'eau dans un écosystème forestier. La démarche proposée amènera les élèves à saisir comment l'équilibre dynamique de ces milieux est constamment fragilisé compte tenu de l'interdépendance entre l'environnement et les activités humaines. 2, record 2, French, - %C3%A9quilibre%20dynamique
