  abstract = {{T}he first step in building predictive models of larval fish assemblages is to identify the main environmental parameters which influence their spatial and temporal structure. {I}n this study, multivariate regression trees ({MRT}) were used to classify hierarchically the effects of large-scale meteorological factors and small-scale water column factors on pre-settlement larval fish assemblages at two sites in the lagoon at {N}ew {C}aledonia, southwest {P}acific. {T}he environmental conditions at one site were highly variable spatially and temporally, but varied little at the other. {I}n spite of these differences, {MRT} models revealed that identical forcing factors influenced the structure of larval fish assemblages at both sites, with a similar hierarchy, but a different statistical efficiency. {A}t a large spatial scale, the seasonal variabilities in sun hours and wind (speed and/or direction) explained 14% and 64% of the structure of larval fish assemblages at the sites of high and low variability, respectively. {A}t a small spatial scale, the seasonal variability in mean surface water temperature, followed by the concentration in {C}hl a, explained 22% and 62% of the structure of assemblages at the sites of high and low variability, respectively. {T}he {D}ufrane-{L}egendre index matched characteristic families of larvae to each set of environmental conditions, and illustrated the role of sheltered, {C}hl a enriched, coastal waters in producing a families-rich assemblage of fish larvae, some species of which are targeted by fishing. {T}his study shows that it may be possible to use environmental data, and predictions computed from {MRT} to design spatially explicit models of larval fish distribution in coral-reef lagoons.},
