DESCRIPTION:Meta-ecosystem theories : species that matter for the cycling o
 f matter\n\nPopulation dynamics ultimately depends on the cycling of matte
 r\, from the uptake of nutrients\, to the recycling of organism. In natura
 l systems\, the movement of matter\, organic and inorganic\, and of organi
 sms can greatly impact ecosystem persistence and functioning over a broad 
 range of spatial scales\, from microbiomes to the biosphere. Meta-ecosyste
 m theories addresses these questions by predicting the dynamics of network
 s of ecosystems\, partially connected by the movement of matter and indivi
 duals. I will introduce the concept of meta-ecosystems and its relationshi
 ps to other similar ecological theories. I will then discuss recent work f
 rom our group based on mathematical models of meta-ecosystem dynamics. The
 se models predict that community structure\, characterized by the trophic 
 position and movement ability of species\, can explain the maintenance of 
 strong spatial heterogeneity and temporal fluctuations when feedbacks resu
 lting from the cycling and transport of matter is considered.\n
