  abstract = {{E}nvironmental conditions triggering egg production and hatching success of copepod species are essential to better understand their population dynamics and consequently their contributions to the production of higher trophic levels. {A} monitoring station was sampled during 2 years in the {T}hau lagoon ({M}editerranean {S}ea) to study temporal successions of 3 {A}cartia congeneric species ({A}cartia clausi, {A}cartia discaudata and {P}aracartia grani). {S}easonal patterns defined the dominance of one {A}cartia species over the two others. {T}here were two perennial species {A}. clausi and {A}. discaudata with maximum abundance in winter and in spring, respectively. {T}he third species {P}. grani occurred in summer and was absent from the water column from {F}ebruary to {A}pril. {E}gg production and hatching success experiments were conducted at each sampling date to determine the different reproductive strategies of the {A}cartia species. {M}aximum egg productions (similar to 25-31 eggs fem(-1) d(-1)) and mean hatching success (similar to 65%) were similar between species but occurred at different periods depending on environmental triggers. {M}odel averaging based on field data showed that temperature prevailed over other variables and that {A}cartia responses were different regarding the species. {T}emperature was the main trigger for egg production of {A}. clausi (negative effect) whereas temperature and salinity should be considered jointly to predict {A}. discaudata egg production. {P}. grani egg production described an uni-modal relationship with temperature. {T}he effect of temperature on hatching success explained strongly the three species dynamics, especially the production of {P}. grani resting eggs.},
