Propagule pressure increase and phylogenetic diversity decrease community’s susceptibility to invasion
2017
Background Invasions pose a large threat to native species, but the question of why some species are more invasive, and some communities more prone to invasions than others, is far from solved. Using 10 different three-species bacterial communities, we tested experimentally if the phylogenetic relationships between an invader and a resident community and the propagule pressure affect invasion probability. Results We found that greater diversity in phylogenetic distances between the members of resident community and the invader lowered invasion success, and higher propagule pressure increased invasion success whereas phylogenetic distance had no clear effect. In the later stages of invasion,…
Harnessing ICT to develop community and identity: a model for academic departments
2006
Universities have been early adopters of Information and Communication Technologies (ICT). However, does availability imply use? How is ICT being used by academic departments? This article addresses these questions, and discusses the use of ICT to support research, instruction and service, but more specifically, the use of ICT to enhance a sense of identity and community across all members of a department. The authors' observations of university departments across the Atlantic reveal very limited uses of ICT. A democratic web-based academic departmental community model is proposed to assist in the strengthening of departmental identity and community as well as advancing its mission. Concept…
