Taxonomy of Marine Flora : 1-19July 2019 - registration open 28th of january
This master degree summer course is a hands-on introduction to marine plants with an emphasis on seaweeds. It trains you to recognise and identify the typical marine algae in various coastal habitats. The organisms are studied in their environment during field trips, and also in vivo back at the laboratory. These studies form the foundation from which the main issues in the systematics, biology, ecology and evolution of marine flora are addressed.
The course includes :
Fieldwork: Five field trips to very contrasting coastal and nearshore habitats are organised. Located within 40 km from Roscoff, the field sites are accessible during low tide. Samples from pelagic and subtidal environments are taken during an outing on one of the SBR’s vessels (when possible).
Practical coursework: in vivo observation of sampled species under a dissecting microscope or optical microscope to study the biological and taxonomic criteria presented during lectures. Each student has access to a microscope and a dissecting microscope during the whole course.
Exercises in using identification keys: Students have access to a number of specialised works and teaching documents designed for the course to identify the species collected during field trips. Students also have access to tools available on-line.
Lectures on the characteristics of the main phyla of seaweed: morphology, anatomy, reproduction, ecology, classification (including molecular phylogeny).
Projects : students participate to a collaborative work to produce a list of native or introduced species that grow in artificial habitats (leisure harbor) of Roscoff. They can also prepare a herbarium.
The course is organised by the Station Biologique de Roscoff, which offers many possibilities for studying the temperate marine flora. It provides access to a a wide range of habitats: rocky to sandy/muddy substrates, exposed to sheltered shores, etc.
The course instructors are research lecturers in phycology who have extensive teaching experience on seaweed biodiversity in coastal and nearshore environments.

Course detailed content
Topics addressed during the course:
Introduction to the systematics, phylogeny and taxonomy of the main groups of seaweeds
Cytological, biochemical, ecological features of the main groups green, red and brown seaweeds; diatoms and dinoflagellates are also briefly introduced
Reproductive features and life cycles of algae
Introduction to marine microalgae and marine plants diversity
Exploration of various coastal habitats; rocky habitats (3 outings), sandy/muddy habitats (1 outing), artificial habitat (1 outing), subtidal and pelagic habitats (1 outing depending on the availabilty pf the vessel), analysis of typical species collected, identification in the field
Analysis of habitats and the effect of biotic and abiotic factors on species distribution (vertical zonation of seaweed, exposure to waves, nature of the substrate, etc.).
Observation of the distinctive characteristics of the main groups of seaweed (cytology, anatomy, reproduction) on live material
Practice in using species identification keys
Practice in preparing slides for observation under the microscope
Extraction and analysis of pigments from frewh algae
Students participate to a collaborative work to produce a list of native and introduced species that grow in artificial habitats (leasure harbor, Roscoff)
Herbaria are prepared
Skills gained and Certification
The course constitutes a solid knowledge base on
the systematics and identification of the major seaweed phyla and the marine species most frequently encountered on English Channel coasts;
methods for determining marine algal species down to the species level;
demonstration of morphological and functional features as well as the lifestyle of seaweeds on the coast;
characterisation of the main types of coastal and nearshore environments along with their typical species composition.
The course is part of the University Pierre et Marie Curie Science of Universe, Environment , Ecology Masters program and the student can validate 6 ECTS units.
The course can be accredited by a Doctoral School.
This course is open 1rst year master students and superior level from French or foreign universities and thrird year undergraduate student if they can prove to have validated their exam before the beginning of the course
These summer schools are also open to continuing professionnal development trainees whose professionnal activities require knowledge in systematics, biology and marine ecology.
The Flora courses is given in english.
Registration for the Flora is handled after the application has been accepted by the head instructors.
