ABSTRACT Feeding success and maternal effects on larval size have long been hypothesized as important contributors to interannual recruitment variability in marine fishes. This study examined the feeding ecology influences of diet size-at-birth length growth rockfishes ( Sebastes spp.). Prey carbon biomass selection were calculated from gut contents, was estimated using otolith core size, recent derived outer increment widths. Biomass contributions preferred prey data integrated into Bayesian hierarchical models predicting growth. Larvae primarily fed selected for copepod nauplii Calanoid copepodites, modulating with ontogeny response availability. Based weight, relative contribution copepodites more strongly positively correlated than that nauplii. Younger larvae experienced faster association copepodite consumption older larvae. Positive radius suggest initial believed be mediated by provisioning, increases likelihood survival, larger These findings ultimately provide evidence selective mediate rockfish survival early life stages.

The contribution of nearshore oceanography to temporal variation in larval dispersal

Patterns of population connectivity shape ecological and evolutionary phenomena from persistence to local adaptation can inform conservation strategy. Connectivity patterns emerge the interaction individual behavior with a complex heterogeneous environment. Despite ample observation that dispersal vary through time, extent which variation in physical environment explain emergent is not clear. Empirical studies its contribution promise illuminate potential source variability shapes dynamics natural populations. We leveraged simultaneous direct observations oceanographic transport simulations clownfish Amphiprion clarkii Camotes Sea, Philippines, assess connectivity. found time-varying on both annual monsoonal timescales partly explained observed patterns, suggesting temporal these timescales. However, interannual mean distance was nearly 10 times expected biophysical simulations, revealing additional biotic abiotic factors contribute variation. Simulated kernels also predicted smaller scale than observations, supporting hypothesis undocumented behaviors such as swimming navigation enhance probability successful away from, opposed retention near, natal sites. Our findings highlight for coincident test hypotheses influence metapopulation persistence, adaptation, other processes.
