标题： Trans-Canada Slimeways: Slime mould imitates the Canadian transport network

摘要： 黏菌Physarum polycephalum在其延伸的身体不同部分之间建立复杂的网络以运输营养物质。 黏菌的原生质网络被优化为最大限度地覆盖营养物质，同时最小化细胞内物质运输的能量消耗。 在实验室实验中，我们用卷曲的燕麦片代表加拿大的主要城市区域，并在多伦多地区接种黏菌。 原质体通过其原生质管网络连接城市区域。 我们揭示了原生质网络与加拿大国家公路网络之间的相似性和差异性，从邻近图的角度分析这些网络，并评估黏菌网络对污染的响应。 显示英文摘要

摘要： Slime mould Physarum polycephalum builds up sophisticated networks to transport nutrients between distant part of its extended body. The slime mould's protoplasmic network is optimised for maximum coverage of nutrients yet minimum energy spent on transportation of the intra-cellular material. In laboratory experiments with P. polycephalum we represent Canadian major urban areas with rolled oats and inoculated slime mould in the Toronto area. The plasmodium spans the urban areas with its network of protoplasmic tubes. We uncover similarities and differences between the protoplasmic network and the Canadian national highway network, analyse the networks in terms of proximity graphs and evaluate slime mould's network response to contamination.
