Modelling the Qualitative Response of Fungal Mycelia to Heterogeneous Environments

摘要: Many species of fungi form a mycelium, an indeterminate system protoplasm-filled, apically extending, branching tubes (hyphae). At the macroscopic level, mycelia produce organisational patterns that are found in many other systems (e.g. nervous and vascular systems). Therefore they provide experimentally observationally accessible model for investigating dynamic origins phenotypic such systems. Moreover, mycelial vital link ecosystem allowing redistribution reutilisation nutrients minerals over far wider spatial domain than would be possible without their presence. In vivo these networks grow function heterogeneous environments therefore to gain any true understanding heterogeneity must taken into account. this paper we develop based on partial differential equations interaction fungal mycelium with environment. Using able test hypothesis react environment global manner by close comparison experimental results, also highlight two specific mechanisms response which central distribution biomass: uptake excess local needs subsequent internal (translocation) excess.
