DOI: 10.1007/s00285-020-01498-7
Abstract: We develop a model of honey bee colony collapse based on contamination of forager bees in pesticide contaminated spatial environments. The model consists of differential and difference equations for the spatial distributions of the uncontaminated… read more here.

DOI: 10.1016/j.jasrep.2017.01.001
Abstract: Abstract The East African Rift system created one of the world's most obsidian-rich landscapes, where this volcanic glass has been used to make tools for nearly two million years. In Kenya alone, there are > 80… read more here.

DOI: 10.1016/j.jasrep.2018.03.009
Abstract: Abstract Forager lifeways in the middle Limpopo Valley, southern Africa, were considerably altered from 350 CE onwards when incoming farmer communities settled the region. This is seen archaeologically in a shift in the preference for… read more here.

DOI: 10.1088/1742-5468/aa7dfc
Abstract: We investigate the dynamics of a greedy forager that moves by random walking in an environment where each site initially contains one unit of food. Upon encountering a food-containing site, the forager eats all the… read more here.

Navigational Experience and the Preservation of Spatial Abilities into Old Age Among a Tropical Forager‐Farmer Population

DOI: 10.1111/tops.12602
Abstract: Abstract Navigational performance responds to navigational challenges, and both decline with age in Western populations as older people become less mobile. But mobility does not decline everywhere; Tsimané forager‐farmers in Bolivia remain highly mobile throughout… read more here.
