Biodiversity in model ecosystems, II: Species assembly and food web structure
Ugo Bastolla, Michael Lässig, Susanna C. Manrubia +1
This is the second of two papers dedicated to the relationship between population models of competition and biodiversity. Here we consider species assembly models where the populat…
Biodiversity in model ecosystems, I: Coexistence conditions for competing species
Ugo Bastolla, Michael Lässig, Susanna C. Manrubia +1
This is the first of two papers where we discuss the limits imposed by competition to the biodiversity of species communities. In this first paper we study the coexistence of compe…
A Solvable Sequence Evolution Model and Genomic Correlations
Philipp W. Messer, Peter F. Arndt, Michael Lässig
We study a minimal model for genome evolution whose elementary processes are single site mutation, duplication and deletion of sequence regions and insertion of random segments. Th…
Structure and evolution of protein interaction networks: A statistical model for link dynamics and gene duplications
Johannes Berg, Michael Lässig, Andreas Wagner
The structure of molecular networks derives from dynamical processes on evolutionary time scales. For protein interaction networks, global statistical features of their structure c…
Diversity patterns from ecological models at dynamical equilibrium
U. Bastolla, M. Laessig, S. Manrubia +1
We study a dynamic model of ecosystems where immigration plays an essential role both in assembling the species community and in mantaining its biodiversity. This framework is part…
Optimizing Smith-Waterman alignments
Rolf Olsen, Terence Hwa, Michael Lassig
Mutual correlation between segments of DNA or protein sequences can be detected by Smith-Waterman local alignments. We present a statistical analysis of alignment of such sequences…
