  abstract = {{R}esting cysts ({RC}s), vegetative cell abundance, sediment characteristics, nutrient and trace metal concentrations were investigated in fifteen stations at {B}oughrara {L}agoon during {O}ctober and {N}ovember 2016. {T}welve morphotypes of {RC} were recorded. {T}he sampling sites showed a similar cyst assemblage trend but differed in total cyst abundance. {T}he cysts of heterotrophic dinoflagellates dominated over the cysts of autotrophic dinoflagellates throughout the study area and were correlated to the abundance of {B}acillariophyceae explained by a likely trophic relationship. {T}he abundance of cysts was positively correlated to phosphorus concentrations measured in the sediment. {A}s well, cysts of {P}olykrikos kofoidii and {S}crippsiella trochoidea were significantly correlated to nitrogen concentrations in water column. {T}he trace metal concentrations did not show any effect on cyst abundances in most cases, except for {C}r on mixotrophic dinoflagellates, suggesting that metal contamination is not determinant in the encystment of dinoflagellates. {A}utotrophic dinoflagellates cyst abundance was dependent on sediment characteristics with the highest densities being recorded in muddy sediments. {T}he hydrodynamics of the lagoon, characterized by a weak water circulation and a low water renewal in the {S}outh-{W}estern zone, was considered among the environmental factors most affecting {RC} distribution. {T}he dominance of potentially toxic species cysts highlights the necessity of monitoring these forms suspected to constitute the precursor of toxic blooms in this area.},
