چکیده

Question: Under what circumstances does a capacity for multi-stage dormancy (i.e. dormancy in more than one life-stage) evolve? Mathematical methods: Optimization in stochastic environments. Results are derived both analytically and by simulations. Key assumption: There exists some trade-off between resources allocated to reproduction and adult dormant survival. Different shapes of this trade-off are investigated. Major conclusions: Multi-stage dormancy can evolve in an environment with low serial autocorrelation. However, a slowly changing environment, with high positive autocorrelation, will prevent the evolution of dormancy in several life-stages. In general, a high positive environmental autocorrelation will separate the evolution of life parameters associated with active life from that of parameters associated with dormant life.

The effects of immigration and environmental variability on the persistence of an inferior competitor.

We tested the hypothesis that temporally autocorrelated variation should increase the abundance of an inferior competitor sustained by immigration. Temporally autocorrelated variability can increase abundance of the inferior species through effects on demography, the strength of competition, and the mean and variance in the abundance of competing species. We allowed the competitive inferior to ...

Seed dormancy and seedling vigour as influenced by planting time environment and date of harvest in rice (Oryza sativa L.)

Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

Multi-objective Differential Evolution for the Flow shop Scheduling Problem with a Modified Learning Effect

This paper proposes an effective multi-objective differential evolution algorithm (MDES) to solve a permutation flow shop scheduling problem (PFSSP) with modified Dejong's learning effect. The proposed algorithm combines the basic differential evolution (DE) with local search and borrows the selection operator from NSGA-II to improve the general performance.  First the problem is encoded with a...

Drift Change Point Estimation in the rate and dependence Parameters of Autocorrelated Poisson Count Processes Using MLE Approach: An Application to IP Counts Data

Change point estimation in the area of statistical process control has received considerable attentions in the recent decades because it helps process engineer to identify and remove assignable causes as quickly as possible. On the other hand, improving in measurement systems and data storage, lead to taking observations very close to each other in time and as a result increasing autocorrelatio...

Multiple risk reduction mechanisms: can dormancy substitute for dispersal?

In a spatiotemporally variable environment, plants use seed dispersal and dormancy to reduce risk. Intuition suggests that dormancy should be able to substitute for dispersal, so that dormancy will reduce the optimal mean dispersal distance, and previous theoretical studies using temporally uncorrelated environments have found this to be true. I show that in the presence of positive temporal co...
