Tissue-specific temporal regulators impinge on the VEGF/Delta-Notch pathway to vary tip cell selection pace yielding diverse densities of vascular network.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
Analysis and modeling of group behavior of adult zebrafish shows that a specialized social interaction mechanism increases foraging efficiency and equality within groups, under a variety of environmental conditions.
Cascades of transient pairwise interactions, stabilized by multisensory inputs, drive the formation of a well-organized social structure from a group of loosely distributed flies.
Collective responses of animals are generally controlled by complex biological mechanisms and in Caenorhabditis eleganscollective dynamics are purely controlled by physical parameters such as oxygen penetration and bacterial diffusion.
A computational model shows that natural selection can cause populations to evolve a distinctive population-level phenotype: the ability to transition between collective states in response to the environment.
The socially exchanged fluid passed mouth-to-mouth during trophallaxis contains molecules that can influence development, potentially mediating communal control of colony phenotypes.
