Consider a finite state irreducible Markov process with transition graph G and invariant probability distribution π. Its inverse communication speed is defined as the expectation of the time to go from x to y when are sampled independently according to π. We study this in the context of both...

This study investigates bone density across the life course among Bolivian Tsimane and Ecuadorian Shuar of Amazonia. Both groups are rural, high‐fertility forager‐horticulturalists, with high lifetime physical activity levels. We test whether Tsimane and Shuar bone density patterns are different...

During human evolution, individuals interacted mostly within small groups that were connected by limited migration and sometimes by conflicts. Which preferences, if any, will prevail in such scenarios? Building on population biology models of spatially structured populations, and assuming...

Set-aside policies providing agronomic and ecological benefits have been mainstream practices in European agriculture. Because they may lead to intensification on cultivated land, they can however have mixed environmental effects. To evaluate the indirect impact of a set-aside policy on crop...
