Publikováno v: Revista de Biología Tropical, Vol 61, Iss 2, Pp 603-644 (2013)
Chironomids, diatoms and microcrustaceans that inhabit aquatic ecosystems of the Northern Neotropics are abundant and diverse. Some species are highly sensitive to changes in water chemical composition and trophic state. This study was undertaken as

Phytotaxa, 2022, 558 (1), pp.103-115. ⟨10.11646/phytotaxa.558.1.7⟩
International audience; Modern diatom assemblages were investigated in the Ounianga Lakes located in the driest part of the Chadian Sahara. These lakes still exist today due to groundwater seepage. They contain a variety of diatom species, one of whi

Publikováno v: The Science of the total environment. 857(Pt 2)
Monitoring the evolution of the Sahelian environment is a major challenge because the great Sahelian droughts, marked by significant environmental consequences and social impacts, contributed, for example, to the drying up of Lake Chad. We combined r
