Recent meta-analyses of fungal diversity using deeply sequenced marker genes suggest that most fungal taxa are locally distributed. However, little is known about the extent of overlap and niche partitions in total fungal communities or functional guilds within distinct habitats on a local forest scale. Here, we compared fungal communities in endosphere (leaf interior), phyllosphere (leaf inter...

In the latest versions of massively multiplayer online games (MMOGs), developers have purposefully made guilds part of game environments. Guilds represent a powerful method for giving players a sense of online community, but there is little quantitative data on guild dynamics. To address this topic, we took advantage of a feature found in one of today's most popular MMOGs (World of Warcraft) to...

Scholars have debated the manner in which religious beliefs influence economic organization. This paper examines a particular case–the craft guilds of medieval England–to show how religious doctrines influence the ability of a group to enforce cooperation. When mortality rates are high, repeated interaction alone cannot sustain cooperation, but spiritual sanctions in the afterlife can sustain c...

The present article focuses on the conditions that allow governments to increase property rights protection because they expect enough income from such action. We develop a behavioral explanation, according to which the answer lies in the growth in the importance, size, and wealth of merchant guilds in the medieval era in Western Europe as well as a somewhat surprising effect of volatile price ...

To understand how communities function and generate abundance, I develop a framework integrating elements from the stress gradient and resource partitioning concepts. The framework suggests that guild abundance depends on environmental and spatial factors but also on inter-guild interactions (competitor or facilitator richness), which can alter the fundamental niche of constituent species in ne...
