What is the origin of behaviour? Although typically associated with a nervous system, simple organisms also show complex behaviours. Among them, the slime mold Physarum polycephalum , a giant single cell, is ideally suited to study emergence of behaviour. Here, we show how locomotion and morphological adaptation behaviour emerge from self-organized...

Significance Simple organisms manage to thrive in complex environments. Having memory about the environment is key in taking informed decisions. Physarum polycephalum excels as a giant unicellular eukaryote, being even able to solve optimization problems despite the lack of a nervous system. Here, we follow experimentally the organism’s response to...

What is the origin of behavior? Although typically associated with a nervous system, simple life forms also show complex behavior – thus serving as a model to study how behaviors emerge. Among them, the slime mold Physarum polycephalum , growing as a single giant cell, is renowned for its sophisticated behavior. Here, we show how locomotion and mor...

Wounding is a severe impairment of function, especially for an exposed organism like the network-forming true slime mould Physarum polycephalum. The tubular network making up the organism's body plan is entirely interconnected and shares a common cytoplasm. Oscillatory contractions of the enclosing tube walls drive the shuttle streaming of the cyto...

Light pollution in the Republic of Croatia is analyzed using a statistical model based on the Walker's law. The results have been verified by measurement of light pollution on some twenty sites. They show that the entire Croatian territory is at least moderately polluted by light, with the exception of several islands and some areas in Lika and Gor...
