Data from: On the evolutionary interplay between dispersal and local adaptation in heterogeneous environments

Andrew M. Berdahl, Colin J. Torney, Emmanuel Schertzer, Simon A. Levin & Andrew Berdahl
Dispersal, whether in the form of a dandelion seed drifting on the breeze, or a salmon migrating upstream to breed in a non-natal stream, transports genes between locations. At these locations, local adaptation modifies the gene frequencies so their carriers are better suited to particular conditions, be those of newly disturbed soil or a quiet river pool. Both dispersal and local adaptation are major drivers of population structure; however, in general, their respective roles are...

Data from: The impact of high-order epistasis in the within-host fitness of a positive-sense plant RNA virus

Jasna Lalić & Santiago F. Elena
RNA viruses are the main source of emerging infectious diseases because of the evolutionary potential bestowed by their fast replication, large population sizes and high mutation and recombination rates. However, an equally important property, which is usually neglected, is the topography of the fitness landscape. How many fitness maxima exist and how well they are connected is especially interesting, as this determines the number of accessible evolutionary pathways. To address this question, we have reconstructed...

Data from: A life-cycle model of human social groups produces a u-shaped distribution in group size

Gul Deniz Salali, Harvey Whitehouse & Michael E. Hochberg
One of the central puzzles in the study of sociocultural evolution is how and why transitions from small-scale human groups to large-scale, hierarchically more complex ones occurred. Here we develop a spatially explicit agent-based model as a first step towards understanding the ecological dynamics of small and large-scale human groups. By analogy with the interactions between single-celled and multicellular organisms, we build a theory of group lifecycles as an emergent property of single cell demographic...

Data from: Social feedback and the emergence of rank in animal society

Elizabeth A. Hobson & Simon DeDeo
Dominance hierarchies are group-level properties that emerge from the aggression of individuals. Although individuals can gain critical benefits from their position in a hierarchy, we do not understand how real-world hierarchies form. Nor do we understand what signals and decision-rules individuals use to construct and maintain hierarchies in the absence of simple cues such as size or spatial location. A study of conflict in two groups of captive monk parakeets (Myiopsitta monachus) found that a...

Data from: Implementation of complex biological logic circuits using spatially distributed multicellular consortia

Javier Macia, Romilde Manzoni, Nuria Conde, Arturo Urrios, Eulàlia De Nadal, Ricard Solé & Francesc Posas
Engineered synthetic biological devices have been designed to perform a variety of functions from sensing molecules and bioremediation to energy production and biomedicine. Notwithstanding, a major limitation of in vivo circuit implementation is the constraint associated to the use of standard methodologies for circuit design. Thus, future success of these devices depends on obtaining circuits with scalable complexity and reusable parts. Here we show how to build complex computational devices using multicellular consortia and space...

Data from: Effects of spatial scale of sampling on food web structure

Spencer A. Wood, Roly Russell, Dieta Hanson, Richard J. Williams & Jennifer A. Dunne
This study asks whether the spatial scale of sampling alters structural properties of food webs and whether any differences are attributable to changes in species richness and connectance with scale. Understanding how different aspects of sampling effort affect ecological network structure is important for both fundamental ecological knowledge and the application of network analysis in conservation and management. Using a highly resolved food web for the marine intertidal ecosystem of the Sanak Archipelago in the...
