Life tables, net reproductive rate, intrinsic rate of increase, generation time,
reproductive value. Growth of individual populations: stability, unstable thresholds; population dynamics in nature; exponential and logistic growth, oscillatory stability and instability, population cycles. Intra- and interspecific competition, predator-prey interactions, k-factor analysis. Please note that the lectures are given in the Czech language, only. English version of the course can be requested in advance if there are at least 5 international students. Last update: VSACH (18.04.2006)

1. Definition of a population from ecological point of view.
2. Demographic analysis of populations. Population with and without overlapping generations. Life tables. Leslie matrix. Stable age distribution and finite rate of increase. Finite rate of increase and stable age distribution derived from life tables. Intrinsic rate of increase. Net reproductive rate and intrinsic rate of increase for continually breeding populations. Generation time. Reproductive value.
3. Population dynamic. Basic principles of equilibrium, stability and regulation. Determinants of stability. Basic types of population dynamic: continuous increase or decrease, equilibrium, population cycles, outbreaks. A basic model: population controlled by positive feedback, inclusion of negative feedback. Analysis of the model: the effects of negative feedback, carrying capacity and logistic growth, neutral stability, oscillatory stability, stability reached by damped oscillations, population cycles, effects of environment. Generalization of the basic model: multiple equilibrium, metapopulation dynamic.
4. Predation. Definition in a broad ecological sense. Basic model of a predator-prey relationship. Behaviour of predator and prey. Synthetic predator-prey models: synthetic models with density dependent predation, synthetic models of predator with non-random search, generation time of predator and prey.
5. Interaction of density dependent and density independent factors. Killing factor. k-factor analysis I: Colorado potato beetle. k-factor analysis II: Winter moth - key factor, regulation factor, model, prediction.
6. Interspecific interactions: definition, basic and realized niche, the principle of competitive exclusion, heterogeneity of environment, enemy free space, the role of evolution.
7. Mutualism: definition, mutualism based on behaviour interactions, mutualism based on planting and rearing, pollination, digestive symbionts, mutualism of fungus and alga - lichen, mutualism of fungi and animals, mycorrhiza, mutualistic fixation of nitrogen Last update: VSACH (13.04.2005)
