This course aims at better understanding the main types of pollutants (organic vs. inorganic), their source(s), their fate in the environment and the way they interact with living organisms (bioaccumulation, biotransformation, effects). The methods used in depollution and bioremediation will be discussed. A particular focus will be made on the contribution of terrestrial and aquatic plants in phytoremediation as well as on the role of microorganisms (bacteria, fungi) in the mechanisms of biodegradation, biotransformation or biosequestration. This course will be illustrated through different case studies through which examples of chronic and acute/accidental pollution of water, air and soil will be discussed. In particular, the treatment of pollution related to mining, petroleum, plastics and phyto-pharmaceutical industries as well as the treatment of liquid effluents (wastewater, industrial effluents) will be discussed. A field trip to Saint-Laurent-Le-Minier will illustrate a current project of phytoremediation of a former mining site.

The expansion of the urban environment is causing fragmentation/destruction of natural habitats, conservation problems and a change in the relationship between man and nature. However, urban areas can also harbor significant biodiversity in close proximity to humans, which can then be used for conservation, awareness raising, human welfare enhancement and even therapeutic purposes. It is a challenge to work in ecology while denying the existence and consequences of the urban environment and its particularities. The aim of this course is to help future professionals in the field of ecology to find a compromise between urban development and respect for nature. Through courses given by various professionals and an outing in Montpellier, the student will discover where (associations, research departments, communities, ...), with whom and how an ecologist can act in urban ecology.

"I - Physical characterization and biogeochemical cycles of coastal marine ecosystems II - Biodiversity and functioning of coastal marine ecosystems III - Law of the coast and the sea; Uses, conflicts and integrated management of the coastal zone. This course offers students a systemic approach to the study of coastal marine ecosystems from a multidisciplinary perspective. The physical structure of these ecosystems will be addressed through courses on their geomorphology and hydrology with a particular interest in the hydric couplings with the open sea and their watersheds. Their biogeochemistry will be addressed in particular to describe the fluxes of carbon and nutrients through the water and sediment compartments. Several aspects of their biodiversity will be illustrated to describe the importance of these ecosystems as a living environment for the species they support and in particular the role of this biodiversity in their functioning will be discussed. The coastal zone is densely populated by humans (40% of the world population). Particular interest will be given to human uses (e.g. aquaculture) and their territorial planning and in particular the evaluation of their ecosystem services in an economic context, management and protection measures (e.g. Marine Protected Areas, Natura 2000) and professionals in the management of these environments will present feedback from concrete experiences. Finally, the implications of the law of the sea for the management of the coastal zone will be taught. "

Sustainable development, ERC sequence, green, blue, turquoise grid.

The aim is to present the regulatory and technical frameworks for integrating the environment into projects, plans and programs. The sequence Avoid, Reduce, Compensate, its stakes, the actors involved, will be presented, discussed and illustrated. The green and blue frames and their interface with the turquoise frame will be analyzed as tools for improving the preservation of biodiversity in land management and development operations.
The students will have to step back from the methods and know-how used to apply this ERC sequence in different fields, linked to plans, developments, programs and having impacts on the environment.

A field trip is an opportunity to meet the actors, the ERC actions deployed, to draw a diagnosis and perspectives.

The applications will focus on the turquoise frame associating biodiversity law and water law file and on the ERC deployment of the development file.

Finally, the EU offers learners a real critical analysis of know-how and the production of innovative and integrative solutions.

Behavioral Ecology approaches the study of behavior from an evolutionary perspective to study the mechanisms, function, and contribution of behavior to evolutionary and ecological processes. The work carried out in Behavioral Ecology helps to understand other phenomena observed in other disciplines of life biology, because all animals, from unicellulars to the most complex vertebrates, exhibit behaviors.

The module allows students to be exposed to the different basic concepts, as well as to the multitude of tools that can be used (observations and experiments in natural populations or on captive individuals, comparative analyses, use of tools from modeling, ecophysiology, molecular biology, biochemistry, embedded electronics...). Part of the training is based on specific discussions on the research approaches that can be used, the tools used and the limits of inferences that can be made. An active participation of the students will be required at these different levels, notably through critical discussions of articles.

The topics covered range from the exploration of food procurement strategies, mate choice, habitat choice, investment in reproduction, to the study of animal communication and the reasons for living in groups. The historical dimension of the discipline is addressed in the introduction, but also according to the sensibility of the speakers and the themes addressed (meaning and relations between 'Animal Behaviour', 'Ethology', Behavioral Ecology etc...).

1 "The way in which the modern West represents nature is the least shared thing in the world" (Descola, 2005, p. 56). According to anthropologist Philippe Descola, the category of "Nature," as a reality separate from the human world, is an invention of Europeans that is only one of the possibilities available to societies to account for the living and non-living beings that surround them.

If Philippe Descola contributes to renewing questions about the relationship between society and the environment, he nevertheless draws on a long tradition in the human and social sciences. Numerous works have already explored the various forms of knowledge and social organization to which these relationships give rise: ethnoscience, anthropology of technology, economic anthropology, ethnoecology, sociology of science and technology, etc.

This issue is far from being confined to the academic sphere. It also arouses the interest of actors in conservation (biodiversity, natural resources, etc.) and industry (pharmacology). It also mobilizes so-called "indigenous" populations who claim, both locally and internationally, access to resources and the preservation of an intangible heritage.

2. Situated at the meeting point of the social sciences and the life sciences, these disciplines analyze how human societies use plants, animals, and other components of the environment, but also how their conceptions and representations of their environment(s) guide these uses. This research also explores how human societies organize themselves, perpetuate themselves, change to adapt to new contexts (globalization, global changes) and transmit knowledge about their relationships with nature.

For a long time, these disciplines focused more specifically on the interrelations between so-called "traditional" societies and their immediate environment. Subsequently, since the 1970s, researchers have reconsidered the distinction between so-called "traditional" and "modern" societies in order to better address new contemporary environmental and social transformations.

Indeed, on the one hand, local societies, even the most isolated, are affected by events that are decided and take place on different scales (international conventions, economic crises). Their immediate environment is also affected by global phenomena (climate change, erosion of biodiversity, etc.). In return, their actions can also have international ecological, social and economic repercussions, when, for example, these societies organize themselves to bring their claims to international arenas.

On the other hand, the relationship that modern societies have with their environment is being reconfigured in the face of the observation that the planet is increasingly "artificialized" and threatened by ruptures and serious crises. The place of fauna and flora is being reconsidered and is the subject of controversy as to their rights. Moreover, the entry into a new geological era, the Anthropocene, is invoked to challenge both the natural sciences and the human and social sciences on the need to consider differently a common history of the environment and societies.

3. The very work of scientists and engineers is apprehended in a new light. In this respect, a new scientific project in the humanities and social sciences aims at reconsidering the role of "non-humans" and calls for finding other analytical categories than those of Nature and Culture. New scales and methods of investigation are also envisaged to analyze global processes.

These recent changes in scale invite the researcher in the humanities and social sciences to (re)consider his or her approach through a reflexive approach: he or she is no longer a simple observer, but can also be a real actor in the processes, when not directly involved in a social movement.

4. The objective of this module is to introduce these different scientific and operational fields. It is to provide students with reference points and elements for reflection, in order to be able to construct scientific questions on the relationships between societies and the environment, in order to reflect on the ways in which current environmental and social issues can be dealt with. The varied geographical and disciplinary experiences of the speakers will make it possible to illustrate the approach through a wide range of ecosystem types, socio-cultural contexts and themes. In the time available, we will not pretend to cover all the themes, approaches and methods in an exhaustive manner. Any student wishing to delve deeper into this area will need to engage in a more in-depth training process.

Climate change, global changes, Prospects, Adaptation, Resilience, Hydrology modeling, Future climate simulation, Water resource availability, Extreme events, Impacts on ecosystems, ecological issues

This course provides students with an introduction to the climatic, environmental and anthropic changes that impact our hydro-eco-socio-systems today and tomorrow.

The activities offer a focus on certain aspects, not exhaustive, of this vast field whose knowledge is constantly evolving.

Beyond the presentation of issues, figures and concepts, students learn about hydrological modeling tools that allow the development of future scenarios of resource evolution. They analyze a concrete subject by crossing disciplines and approaches. They discuss the possibilities of adapting to the impacts of changes.

The activities consist of 3 parts: The course activity, the modeling activity, and the bibliography activity.

- During the course, the principles of climate modeling, the construction of climate change scenarios and their limits are explained. The orders of magnitude of the main changes are stated, as well as the major issues of sustainable development, climate change and global change. A particular focus is proposed around the French Mediterranean watersheds (climate change hot spot, decreasing availability of water resources, agricultural practices and adaptations, irrigation, tourism...).

- The concepts of hydrological modeling and calibration in a non-stationary or poorly gauged context are taught and an introduction to hydrological modeling is carried out with an application case. The students manipulate general hydrological models allowing to evaluate flows and balances (of type GR, HEC-HMS or WEAP), to feed them with outputs of climatic models, to generate future scenarios of flow and balance, then to criticize the scenarios thus built. The modeling work done in small groups is the subject of an oral presentation.

- Finally, the bibliography done in class and completed independently should allow students to specialize around a concrete case of the study of a change occurring in a compartment of a natural or urbanized hydro-eco-system (that the students choose). They carry out a literature review to identify the societal or environmental issues arising from these changes, as well as the scientific questions inherent in the implementation of measures to reduce their impacts or to adapt. They must identify how their case study is similar to other cases, but also how it differs from them. Finally, they open their analysis to a more general methodology that can be applied to other case studies to characterize these changes, their impacts and the adaptation measures. The students write

a synthetic note for operational purposes (bibliography, similar studies, controversies, operational tools, protocols, orders of magnitude). Then they make a pitch of their results to the class.
