DESCRIPTION:Speakers: Yael Artzy-Randrup (University of Amsterdam )\nA cen
 tral debate when studying ecological communities concerns the relative imp
 ortance of selective processes relative to stochastic ones. This has signi
 ficance for understanding the dynamic behaviour of these systems\, for ass
 essing features such as fragility and resilience\, and ultimately\, for de
 termining how to correctly approach them. At the core of dealing with this
  challenge is the need to link ‘observed patterns’ with the ‘underly
 ing processes’ that created them\; this is a long-standing well known ch
 allenge in the arenas of ecology and evolution. The application of network
 s in ecological theory can provide a useful perspective and toolkit for de
 aling with this challenge. Indeed\, in many cases the selective forces act
 ing on individual species are frequency dependent and hence need to be pla
 ced in a community framework in order to understand their ecological role 
 as it depends on the rest of the network\, and how the functioning of the 
 whole network depends on them. \n\nDiversity has played a central role in 
 most studies that address the relationships between structure and function
  in ecological-network. Here I discuss different views on the concept of d
 iversity\, both as an indicator of system functioning and as an emergent p
 roperty of these systems. As a case study I specifically focus on pathogen
  communities\, where ecological and evolutionary feedbacks act on short ti
 me scales.\n\nhttps://conferences.maths.unsw.edu.au/event/2/contributions/
