    Advances in Biochemical Indices of Zooplankton Production
    (Elsevier Academic Press Inc, 2017) Yebra, Lidia; Kobari, Toru; Sastri, Akash R.; Gusmão, Luiz Felipe Mendes de [UNIFESP]; Hernandez-Leon, Santiago; Gusmão, Felipe [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Several new approaches for measuring zooplankton growth and production rates have been developed since the publication of the ICES (International Council for the Exploration of the Sea) Zooplankton Methodology Manual (Harris et al., 2000). In this review, we summarize the advances in biochemical methods made in recent years. Our approach explores the rationale behind each method, the design of calibration experiments, the advantages and limitations of each method and their suitability as proxies for in situ rates of zooplankton community growth and production. We also provide detailed protocols for the existing methods and information relevant to scientists wanting to apply, calibrate or develop these biochemical indices for zooplankton production.

    Female-biased sex ratios in marine pelagic copepods: Response to Hirst et al. (2013)
    (Inter-research, 2013-01-01) Gusmão, Luiz Felipe Mendes de [UNIFESP]; McKinnon, Alexander David; Richardson, Anthony J.; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP); Univ Queensland; CSIRO Marine & Atmospher Res
    Hirst et al. (2013; Mar Ecol Prog Ser 489:297-298) suggest that Gusmao et al. (2013; Mar Ecol Prog Ser 482:279-298) misinterpreted the findings of Hirst et al. (2010; Limnol Oceanogr 55:2193-2206). They restate that the major factors determining sex ratio in pelagic copepods act upon the adult stage, but they place less emphasis on the idea that predation on male copepods is a likely determinant, and highlight the role of physiological longevity. Here we reconsider the data and confirm our position that at present there is limited evidence to support the theory of male-skewed predation. However, we agree that sex determination is governed by a combination of factors, with the relative emphasis being the main point of contention between the 2 parties.
