“…These more typical community responses have been shown to occur in mesoscale eddies in the NPSG (Landry et al, ) and in the North Atlantic subtropical gyre (Goldthwait & Steinberg, ), where shifts in phytoplankton size structure are reflected in increased mesozooplankton biomass and larger organisms. Our results also do not agree with the negative relationships between zooplankton size diversity and productivity in the East China Sea (García‐Comas et al, ) and Chilean upwelling systems (Medellín‐Mora et al, ), where shifts toward smaller zooplankton (juveniles) occur in response to productivity pulses. While we did not find a relationship (linear or nonlinear) between NB‐SS slopes and PP, Sprules and Barth () have observed that the NB‐SS index is not always sensitive to productivity changes, as, for example, in the East China Sea (García‐Comas et al, ).…”

“…In dynamic regions of the oceans, variability in system productivity is well demonstrated to modulate significant shifts in the size structure of zooplankton communities (Décima et al, ; Manríquez et al, ; Medellín‐Mora et al, ; Rykaczewski & Checkley, ). While the magnitudes of environmental variability are much smaller in the subtropical open oceans (Quiñones et al, ; Rodríguez & Mullin, ; Sprules & Munawar, ), here we show that systematic changes in size structure can also occur in such systems.…”

“…ovigerous females) and the early stages of the life cycle (i.e. eggs and larvae) are exposed to the seasonal variations in temperature (Medellín‐Mora, Escribano, & Schneider, ) and food availability (i.e. quantity of organic matter; Guiñez, Valdés, & Siffedine, ), and in the amounts of chlorophyll (Morales et al., ) and zooplankton in the water column (Anabalón, Morales, Escribano, & Varas, ; Bottjer & Morales, ; Escribano, Hidalgo, Fuentes, & Donoso, ; Escribano & Schneider, ) that occur in temperate regions such as the Chilean coast.…”

“…These studies provide insight into the characteristics of the ecosystem as a whole but provide little understanding of the structure and function of the particular biological communities of direct importance to planktivorous fish. However, continued development of zooplankton imaging methodologies and their application to process zooplankton collected during regular oceanographic surveys has fostered insight into the relationships among hydrographic processes, biogeochemical conditions, and mesozooplankton size spectra and the potential implications for fish recruitment (Grosjean et al 2004, Irigoien et al 2009, Manriquez et al 2009, Medellin-Mora et al 2016.…”
