Journal Article
Aquatic Ecosystem Health & Management (2017) 20 (4): 369–377.
Published: 02 October 2017
...Esteban M. Paolucci; Leila Ron; Hugh J. MacIsaac Species richness and species abundance (colonization pressure and propagule pressure, respectively) are commonly used to characterize invasion risk for ballast-water-mediated introductions, which can be high if either parameter is high. For practical...

... tanapelagius , and to some extent the benthopelagic Barbus humilis , transferred energy from zooplankton to the top level of the food web. Barbus humilis is a vector of energy and biomass from detritus to top predators. Pelagic fisheries are proposed as an option to reduce fishing pressure on the endemic...

Published: 03 July 2015
...Patricia M. Glibert While increased propagule pressure may increase the possibility of success of an invading species, success is also a function of the environment to which the organisms have been introduced and the physiological strategies of the invading organisms and how those strategies relate...

...Hugh J. MacIsaac; Mattias L. Johansson Considerable attention has been focused on the concept of Propagule Pressure (number of individuals introduced and introduction events) as a predictor of invasion success (975 papers). Much less well studied is the role of Colonization Pressure (number of...
