Cooperation and Punishment in the Arbuscular Mycorrhizal Symbiosis: Implications for Resource Exchange & Biological Market Dynamics
… This reciprocal reward system is analogous to a market economy, where trade is favored with partners offering the best rate of exchange. Our results also demonstrate that fungi are able to distinguish among host plants interconnected by common mycorrhizal networks (CMN) that differ in the benefit …

Adaptive value and development of nest-building in Red Bishops (Euplectes orix)
… are analysed and discussed as a commodity in a biological market. In a pilot study, forebrain regions were identified that are involved in the neural control of nest-building behaviour, using ZENK expression as a marker for forebrain activity. Large-scale screening of the forebrain was possible …

Social interaction and dispersal patterns of golden snub-nosed monkeys (Rhinopithecus roxellana) living in multi-level societies
… kin selection theory, reciprocity theories, or biological market theory. Behavioral observations for this study were conducted at Zhouzhi National Natural Reserve, Shaanxi, China. A habituated band of snub-nosed monkeys was followed from September 2007 to August 2008. Along with behavioral …

Genetic And Temporal Variation In Resource Exchange Between An Ectomycorrhizal Fungus, Rhizopogon Occidentalis, And Seedlings Of Pinus Radiata
Various economic theories have been adapted to explain the evolutionary persistence of resource exchange mutualisms such as mycorrhizae. The ratio of resources exchanged is an important variable comto all these models. Measuring resource exchange ratios is the first step in testing the hypotheses …
