Marine ecology
The ocean is the largest biome on the biosphere, and the place where life first evolved. Life in a viscous fluid, such as seawater, imposed particular constraints on the structure and functioning of ecosystems, impinging on all relevant aspects of ecology, including the spatial and time scales of variability, the dispersal of organisms, and the connectivity between populations and ecosystems.
The Marine Ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic and biotic features.
Marine ecology is a subset of the study of marine biology and includes observations at the biochemical, cellular, individual, and community levels as well as the study of marine ecosystems and the biosphere.
The course of Marine Ecology provides an introduction to ecology focuses on specific marine ecological concept, covering interactions between marine organisms and the environment at scales of populations, communities, and ecosystems.
Main Outline contents
- The Mediterranean Sea: the place to be (this bassin is ideal to understand the basic concepts in Marine ecology (colonization, climax, invasive species, human impact...)
- Ecology of the some marine communities: Posidonia oceanica meadow, from estuaries to rocky shores to polar regions, ... and with afocus on anthropogenic impacts.
- General concepts in ecology applied to marine ecology: definitions, ecologial factors, production, productivity, trophic webs, interspecific relations, competition, predation, zonation of organisms,...

Marine ecology
The course will
- give a basic knowledge of ecological characteristics and processes in the marine environment.
- show the importance, complexity and fragile aspects of different types of marine habitats.
- be abble to explain the factors that determine the spatial and temporal distributions and abundance populations and communities of marine organisms in relation with biotic and abiotic factors.
- be abble to apply ecological principles
- be abble to work constructively both independently and collaboratively and communicate effectively about Marine Ecology (issues and ideas) using language that can be understood by the public and scientists.
- use some methods applied in marine ecology during the field trip.
- develop ability to collect, analyse and interpret marine ecological data.
Introduction to marine ecosystems modelling
The main aim of this course is to learn how to conceptualize, parameterize and implement mathematical models of marine biogeochemical and ecological processes
Marine ecology fieldtrip
Students should
- develop testable alternative hypotheses for the causes underlying the observed patterns.
- design and carry out appropriate empirical tests of the predictions of hypotheses to explain the observed patterns.
- describe spatio-temporal patterns in marine populations and communities, and investigate the underlying processes producing such patterns at multiple scales.
Students should become independent in:
- exploring theories and models in marine ecology;
- identifying and describing patterns and causal processes in marine ecosystems.
- conducting observational and experimental ecological research;

Marine ecology
- Lectures and sessions of discussion
- A field trip in Corsica at STARESO, compulsory
Introduction to marine ecosystems modelling
The half part of the time will be devoted to the implementation of very simple examples in order to get familliar with models implementation
Marine ecology fieldtrip
A week in the field at STARESO in Corsica. The student will receive a question at the beginning of the week. It will have to develop a measurement and sampling protocol to meet them.
The student will be guided throughout the week through discussions with the supervisors.
Two mandatory field days are scheduled to visit Pairi Daiza Park and the Zwin Nature Reserve. These visits are intended to enhance understanding of species conservation and coastal ecosystems, as well as marine ecology.
Student attendance is compulsory.
Mode of delivery (face to face, distance learning, hybrid learning)
See OCEA0057-B-a and OCEA0057-A-b to have a full description.

During the field trip (station STARESO of the University of Liège- Calvi Corsica) the concepts to a practical study of the distribution of the marine organisms in relation to biotic and abiotique factors are applied.
These approaches are made in snorkelling, in scuba diving* followed by determinations under binocular, photographic documents taken by the student.
*not compulsory
* not compulsary, only possible if you have your licence and a medical check-ups done less than 12 months ago
