DESCRIPTION:*Abstract*: Systems thinking is an old but reviving attitude i
 n modern ecology. One of its most hopeful tools is network analysis. Beyon
 d studying the large-scale\, macroscopic properties of ecological networks
 \, it seems to be increasingly interesting to reveal also the local and me
 so-scale properties of these webs. I will discuss several new techniques f
 or characterizing part-to-whole relationships in ecological systems and th
 e computational challenges they raise. In particular\, various centrality 
 measures for individual nodes and node sets will be presented\, their rela
 tionship and relevance will be illustrated. Beyond measuring centrality\, 
 I will offer an approach to measuring uniqueness in a topological sense. F
 inally\, three studies on how to link structure to dynamics will be presen
 ted. I will conclude by discussing the future of systems-based conservatio
 n.\n\n*Biography*: Ferenc Jordán was born in Budapest\, Hungary\, on 11 J
 une 1973. He studied Biology (MSc 1996) and received his PhD in Genetics (
 1999) from Eötvös University\, Budapest. Ferenc was an assistant profess
 or at the Department of Genetics\, Eötvös University (1999-2002)\, a pos
 tdoctoral researcher at the Department of Ecology and Plant Taxonomy\, Eö
 tvös University (2002-2003)\, an associate professor at the Institute of 
 Ecology and Botany of the Hungarian Academy of Sciences (2003-2006) and a 
 research professor at the Animal Ecology Research Group of HAS (2007-2008)
 . He was also a Junior Fellow (2000/2001) and Branco Weiss Fellow (2003-20
 08) at the Collegium Budapest\, Institute for Advanced Study. The latter w
 as supported by the Society in Science foundation\, ETH\, Zürich\, Switze
 rland. Ferenc has given a number of talks in different countries (from Ind
 ia to Taiwan and from the US to South Africa) and maintains a rich network
  of collaborators in 8-10 countries. He was a participant in the Darwinian
  Homeland Security workshop organized at NCEAS\, Santa Barbara\, CA (2005)
 \, and is an editor for Ecology Letters. Ferenc joined CoSBi in October 20
 08.
