Summary
“Alimentary barcoding”: development of a new molecular ecology tool for freshwater
environments.
Example through studying Durance hybrid zone between the two French
Chondrostoms.
Hydroelectric settlement could lead to affect trophic resources availability for fish
populations, mainly for benthos feeder species.
Previous works demonstrated that in the
Durance River (an highly man-impacted river), many morphological and ecological
characteristics were moved in compare to reference station’s populations for the two benthic
feeders species, Chondrostoma toxostoma toxostoma (Ctt, endemic species) and
Chondrostoma nasus nasus (Cnn, introduced species) and their hybrids.
To better understand
which environmental factors are responsible of these differences, we studied the diet behavior
of the two Chondrostoma species.
The main goal of this thesis was so to study the diet
behavior of the two Chondrostoma species and their hybrids in the Durance River and to
