Tree crickets can optimize the baffles they make to increase call loudness without any progressive optimization, and manufacture an optimal baffle in a single attempt, by using a simple yet highly accurate heuristic.
Feedback sensing of the intracellular calcium concentration suffices to reproduce the diversity of ionic conductances underlying normal cardiac electromechanical function in a genetically diverse population of mice.
A computational model for the formation of neural networks of grid cells in virtual bats suggests that the highly ordered networks presumed to support spatial navigation in two dimensions cannot be routinely established in three-dimensional space.
The cessation of major anthropogenic disturbances since European colonization in the forests of central Africa leads to a canopy closing, and to the disappearance of certain light-demanding tree species.
The spatial interactions between humans, large carnivores and herbivores cascade down in a complex but predictable way to lower trophic levels affecting regeneration of tree species in a temperate forest.
Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.
