Cooperation is a fundamental aspect of biological systems. The evolution of complex organism, intelligence and complex societies all depend on cooperative behavior.

A fully autonomous unmanned system has the ability to gain information about and navigate through an environment, to work for an extended period withou...

In this study, we report evidence that temperature plays a key role in determining the relative abundance of two mutualistic fungi associated with an economically and ecologically important bark beetle, Dendroctonus ponderosae. The symbiotic fungi possess different optimal temperature ranges. These differences determine which fungus is vectored by dispersing host beetles as temperatures fluctua...

As opposed to animals, plants have to cope with the resources, environmental restrictions, herbivores, and pathogens they find in the particular spot where they are bound to grow. Hence, resource sequestration, predation and competition relationships, and adaptation to various sources of other environmental stresses and their seasonal variation must be flexible enough to ensure survival and suc...

Red flags, censored newspapers, directed excursions, indoctrinated schools, motivated plays, didactic pictures, and continuous radio messages preach communism.

The authors provide information on current assessmen...
