Objectives

Understand the basic concepts in the field of ecology and acquire the capacity to use them to interpret and act on a real world context.

Program

A - THEORETICAL PROGRAM

I – Introduction
Ecology: meaning, terminology and scope. Multidisciplinarity.
The development of Ecology. Importance of ecological studies.
General organization of the Biosphere: spatial and trophic structure.

II – The ecosystem
Components of ecological systems: abiotic and biotic components. Ecotypes. Regulating factors: temperature, photoperiod, water, atmospheric gases, biogenic salts. The water cycle.
Biological control of the chemical environment. Organic matter decomposition. Matter recirculation in ecosystems.


III – Ecosystem functioning
The nature of energy. Energy and materials. Flow of energy in different ecosystems. Primary production and environmental controls on primary production. Pattern of world distribution of primary productivity.
Secondary production.
Food chains and trophic levels. Major food chains. Ecological pyramids.
Energy budget. Ecological efficiencies.

IV – Biogeochemical cycles
The basic types of biogeochemical cycles.
Major biogeochemical cycles: the carbon cycle, the nitrogen cycle, the phosphorus cycle.

V- Populations. Density, natality, mortality, migration. Population growth. Life tables. Age structure. Survival curves.
Species interactions: neutralism, protocooperation, mutualism, comensalism, coevolution. Competition (intra and inter specific).The Lotka-Volterra model. The Tilman model. Predation.
Metapopulations: concepts and aplications.

VI - Communities. Taxocenosis and guild. Properties: species composition, diversity, dominance, equitability, growth. Similarity of communities. Classification of communities.
Biodiversity. Species richness. Statistical distributions (log-normal, broken stick), diversity indexes (Shannon-Weaver and Simpson). Geographic patterns. Latitudinal gradient theory. Islands biogeography. Ecological niche.
Influence of competition and predation on the structure of communities.
Ecological sucession. Primary and secondary sucession. Seral communities and climax communities.

VII - Ecosystems. Stability, constancy, resilience, resistence, persistence. The intermediate disturbance theory. r and K strategies. 9 keys to understand ecosystems: interactions; matter and energy flows; dinamics; diversity; space and time ocupation; relations between physico-chemical factors and biological factors; ecosystem evolution; ecosystem interactions.
Life strategies.


VIII – Biomes
Main characteristics of major terrestrial and aquatic ecosystems of the world.

B - PRACTICAL PROGRAM
- Sampling strategies in ecology;
- Population density determination: capture per unit effort; capture-recapture methods.
- Modal progression analysis: Battacharya method.
- Life tables analysis
- Methods for studying communities: similarity, dendrograms.
- Visualisation of documentaries about several biomes of the world. Discussion and comentary.
