GIS Modeling of Desert Root Crop Maturation on the Mid-Columbia Plateau
… movements timed to efficiently utilize available resources. Desert roots, such as lomatium and bitterroot, provided a primary source of dietary nutrition, yet the ideal conditions for exploiting these plant resources coalesced for a very limited time in any one location. It was therefore necessary …

Human-Plant Interactions in Semi-Arid Regions: An Archaeobotanical Study of the Iron Age Site of Mtanye, Southwestern Zimbabwe
Humans have always interacted with plants for thousands of years ago. The origin of plant domestication is a clear example of human-plant mutualism. This mutual relationship has gradually developed into a co-entangled relationship where both symbionts benefit each other in an environment. The …

Polyspecific Associations of Callimico Goeldii, Saguinus Labiatus, and Saguinus Fuscicollis in Acre, Brazil
… season C. goeldii fed extensively on fungus and plant exudates, and both species of Saguinus fed on more exudates and nectar. There were low levels of agonistic interactions among species, suggesting that the PSAs do not impose heavy costs due to direct contest competition. Based on species' …

The effects of endophytic Fusarium verticillioides on the interactions of maize and its fungal pathogen Ustilago maydis.
… fungi, endophytes and pathogens inhabit plants, interact with each other, and affect their fitness. Although theoretical studies suggest that the outcomes of multispecies interactions are often different from those of pairwise interactions, most empirical studies have focused on pairwise …

Niche construction and plant-use in the Mesolithic
In Britain and north-west Europe, the human-plant interactions of Mesolithic hunter-gatherers have been the focus of debate and study for nearly 60 years. The archaeobotanical and pollen records from these regions suggest that Mesolithic people actively constructed their own niches through the use …
