Local population of Eritrichium caucasicum as an object of mathematical modelling. I. Life cycle graph and a nonautonomous matrix model
TLDR
The prospects of model experiments with a logically nonautonomous model to forecast the long-term dynamics of E. caucasicum and the technique that constructs a virtual absorbing Markov chain and calculates its fundamental matrix is applied to obtain “age-specific parameters” from a stage-classified model.

How Long Does a Short-Lived Perennial Live? A Modeling Approach
TLDR
The model indicates that A. albana plants spend most of their life spans as virginal adults, which characterizes the space holder strategy by Körner (2003), or the delayed-development strategy by Zhukova (1995), which gives another evidence that the A.Albana population is endangered.

Local Population of Eritrichium caucasicum as an Object of Mathematical Modelling. II. How Short Does the Short-Lived Perennial Live?
TLDR
Given the data of 6-year observations, the forecast of whether the local population increases/declines in the long term draws on the range of possible variations in the measure λ1(G) under reproductive uncertainty, and this range localizes entirely to the right of 1, though very close to λ 1 = 1 meaning a stable population.

Local Population of Eritrichium caucasicum as an Object of Mathematical Modelling. III. Population Growth in the Random Environment
TLDR
An alternative mode of prediction is based on the (upper and lower) estimates of the stochastic growth rate (λS) of the population in a random environment, which has been formed in the model by a random choice from 8 annual matrices distributed equally probable and independent of the choice made at the previous step.

Disappointing Survival Forecast for a Local Population of Androsace albana in a Random Environment
TLDR
The task is motivated to construct a more adequate model for choosing annual matrices, in which the probability of choice would be related to the dynamics of the real habitat factors for a given local population.

TLDR
The response of an alpine highly productive plant community to soil nutrient addition and irrigation in the northwestern Caucasus, Russia, found that aboveground biomass did not change significantly, but the biomass increased by 25% in the case of the treatment with calcium addition compared with the control.
