Declining oxygen is one of the most drastic changes in the ocean, and this trend is expected to worsen under future climate change scenarios. Spatial variability in dissolved oxygen dynamics and hypoxia exposures can drive differences in vulnerabilities of coastal ecosystems and resources, but documentation of variability at regional scales is rare in open-coast systems. Using a regional collaborative network of dissolved oxygen and temperature sensors maintained by scientists and fishing cooperatives from California, USA, and Baja California, Mexico, we characterize spatial and temporal variability in dissolved oxygen and seawater temperature dynamics in kelp forest ecosystems across 13° of latitude in the productive California Current upwelling system. We find distinct latitudinal patterns of hypoxia exposure and evidence for upwelling and respiration as regional drivers of oxygen dynamics, as well as more localized effects. This regional and small-scale spatial variability in dissolved oxygen dynamics supports the use of adaptive management at local scales, and highlights the value of collaborative, large-scale coastal monitoring networks for informing effective adaptation strategies for coastal communities and fisheries in a changing climate.

Consistent with Response Styles Theory, this study aimed to examine the prospective associations between changes in response styles and depressive symptoms during mid-adolescence, with a focus on gender differences. A 2-year longitudinal study was conducted consisting of three waves, each separated by 1 year. The participants were 663 Spanish adolescents ( M = 13.50, SD = .75) who individually completed the Children's Depression Inventory-Short and a short version of the Children's Response Styles Scale. Girls showed higher rumination and lower distraction than boys and more depressive symptoms. A multivariate latent growth curve model indicated that the increase in depressive symptoms during mid-adolescence in girls was associated with an increase in rumination and a decrease in distraction. After a 2-year follow-up, changes in response styles to negative affect (in rumination and distraction independently and in the ratio score) were interrelated with the changes in depressive symptoms in adolescent girls.
