A unified mechanistic model of niche, neutrality and violation of the competitive exclusion principle Nature Precedings
Lev V. Kalmykov; Vyacheslav L. Kalmykov.
The origin of species richness is one of the most widely discussed questions in ecology. The absence of unified mechanistic model of competition makes difficult our deep understanding of this subject. Here we show such a two-species competition model that unifies (i) a mechanistic niche model, (ii) a mechanistic neutral (null) model and (iii) a mechanistic violation of the competitive exclusion principle. Our model is an individual-based cellular automaton. We demonstrate how two trophically identical and aggressively propagating species can stably coexist in one stable homogeneous habitat without any trade-offs in spite of their 10% difference in fitness. Competitive exclusion occurs if the fitness difference is significant (approximately more than 30%)....

Generalized Theory of Life Nature Precedings
Vyacheslav L. Kalmykov.
The paper is mathematically, physically and biologically inspired - it is a deductive attempt of the biologist to find the most appropriate language for modelling of life. Applications of mathematical structures - groupoids, groups, categories, functors and monads, which are the most effective for the description of the complex objects, are discussed. Some new conceptions and interpretations were introduced: unified classification of complex systems; the generalized conception about stationary states of any autonomous agent ("Statology"); the total quantitative criterions of evolutionary direction; the generalized group of symmetry. The definitions of information, entropy, organization, behavior, evolution, creation, life, culture,...

Inter-Tunneling Mechanism of Colliding Population Waves Nature Precedings
Lev V. Kalmykov; Vyacheslav L. Kalmykov.
Here we show a new interaction mechanism of colliding population waves. It provides a stable coexistence of two similar but different species competing for the same limiting resource during their asexual propagation in a limited homogeneous environment under constant conditions. The revealed mechanism opens new opportunities in conservation biology.

Mechanistic mechanisms of competition and biodiversity Nature Precedings
Lev V. Kalmykov; Vyacheslav L. Kalmykov.
The nature of competition and biodiversity are open basic questions since Darwin. To investigate mechanisms of interspecific competition and their contribution in biodiversity as closely as possible we offer a white-box modelling method based on physically interpreted ecological axioms. These models are implemented as deterministic individual-based cellular automata and able to give a direct physico-mechanistic insight into studied phenomena. Competition of two trophically identical but fitness different species, competing for one limiting resource in one stable uniform habitat (which is closed for immigration, emigration, predation, herbivory and parasitism) has been investigated in conditions, which are the most unfavourable for their coexistence. The...

Strong and weak competitors can coexist in the same niche Nature Precedings
Lev V. Kalmykov; Vyacheslav L. Kalmykov.
The competitive exclusion principle postulates that two trophically identical but fitness different species can not stably coexist in the same niche. However, this principle contradicts the observed nature's species richness. This fact is known as the biodiversity paradox. Here, using a simple cellular automaton model, we mechanistically show how two trophically identical, but fitness different species may stably coexist in the same niche. As environment is stable and any trade-offs are absent in this model, it strongly violates the competitive exclusion principle.

Strong violation of the competitive exclusion principle Nature Precedings
Lev V. Kalmykov; Vyacheslav L. Kalmykov.
Bacteria and plants are able to form population waves as a result of their consumer behaviour and propagation. A soliton-like interpenetration of colliding population waves was assumed but not proved earlier. Here we show how and why colliding population waves of trophically identical but fitness different species can interpenetrate through each other without delay. We have hypothesized and revealed here that the last mechanism provides a stable coexistence of two, three and four species, competing for the same limiting resource in the small homogeneous habitat under constant conditions and without any fitness trade-offs. We have explained the mystery of biodiversity mechanistically because (i) our models are bottom-up mechanistic, (ii) the revealed...
