Abstract Fungi are found ubiquitously in the mammalian gut however role of commensal fungi host is poorly understood. Laboratory mice used to model host-fungi interactions due ultra-clean housing they do not harbor fungi. The human fungus Candida albicans widely studied dissect host-commensal prior dysbiosis bacteria required colonize laboratory mice. Insights from such forced host-fungal unsui...

Following the critical analysis of the concept of “sustainability”, developed on the basis of exergy considerations in previous works, an analysis of possible species “behavior” is presented and discussed in this paper. Once more, we make use of one single axiom: that resource consumption (material and immaterial) can be quantified solely in terms of exergy flows. This assumption leads to a mod...

Mineral nutrient limitation seems to stimulate phytoplankton excretion of extracellular organic carbon (EOC). Bacterial growth on EOC requires additional uptake of mineral nutrients. A paradoxical situation is thereby created: algae stressed by lack of mineral nutrients respond in a manner whereby they stimulate their competitors for the lacking nutrients. To investigate this paradoxical ecolog...

In the current paper, we propose a two-prey-one-predator system with Holling type II predation functional response where prey species consumes the remains of the other prey species’ carcass given by their predator. Mathematical analysis of the proposed model equations with regard to non-negative invariance including stability and bifurcation are carried out. Next, we extend the deterministic sy...
