Continental experiments and sampling

Presentation

This experimentation and field service is essential for the monitoring and describing species. Using tools such as marking, photographic trapping, GPS beacons and transects, researchers can study current ecosystems or reconstruct past events (climate, vegetation, etc.) using core sampling techniques. This monitoring enables us to gain a better understanding of biodiversity and ecosystem functioning, and to analyse the impact of human pressures on these ecosystems.. By combining these data with controlled experimental conditions, it is possible to anticipate the responses of species to future environmental changes and adapt conservation efforts accordingly. Such monitoring provides a more detailed understanding of biodiversity and is essential for protecting threatened species and restoring habitats.

This monitoring is carried out in different environments such as cliffs, meadows, lakes, peat bogs, etc.

OSU Pythéas Experimental Botanical Garden

The St Jérôme botanical garden includes three greenhouses and several experimental areas dedicated to the study of Mediterranean plants. These areas benefit from real-time monitoring of microclimatic conditions (temperature, humidity, rainfall, light, wind) using the COOPERATE database from the ECOREV federation and OSU Pythéas. An additional greenhouse is located at l'Arbois.

In addition, 16 phytotrons at the St Jérôme and l'Arbois sites provide precise control of temperature, light and humidity for experiments on plant growth and micro-organisms.

Scientific objectives

The garden's facilities allow you to study :

- The impact of climate and environmental factors on plant germination and growth.

- Biotic interactions (competition, herbivory, pollination) influencing plant reproduction.

- The correlation between in situ conditions and in vitro models.

- Key environmental parameters for studying Mediterranean ecosystems.

- Experimental plant cultures under semi-controlled conditions.

Instrumentation and equipment

The garden is part of the COOPERATE observation networks of the ECOREV federation and the OSU Pythéas and has :

- A weather station measuring temperature, humidity, rainfall, wind and sunshine.

- Water potential sensors (Campbell 229) recording data every hour.

- An automated system for collecting and transmitting data to COOPERATE.

- Automated watering systems that allow you to modify the water factor.

- Greenhouses of various sizes to exclude rain and grow frost-free plants.

- Warehouses and laboratories in situ for handling sediment and soil.

Educational trail

The garden contains a collection of more than 250 plant species of subtropical and Mediterranean origin, used by Aix Marseille University's biology/ecology teaching staff for botanical observations and supervised research projects, and for school visits organised by the E4 association (Ecological Expertise and Environmental Education) http://expertiseecologique.free.fr - http://e4asso.over-blog.com/
