    Exploring gaps in mapping marine ecosystem services: A benchmark analysis
    (ELSEVIER SCI LTD, 2020) Nahuelhual, L.; Vergara, X.; Bozzeda, F.; Campos, G.; Subida, M. D.; Outeiro, L.; Villasante, S.; Fernandez, M.
    We assessed the gaps between current and "model mapping routines", which represent a benchmark for mapping marine ecosystem services (ESs). Model mapping routines comprised 17 selected variables and their best-rated alternatives depending on the mapping purpose, namely, marine spatial planning, environmental impact assessment, vulnerability and risk analysis, marine protected areas management, payments for ecosystem services, and natural resources management. We conducted a systematic search of articles (n = 64) from which information on the 17 variables and their alternatives was retrieved. We assessed gaps using similarity matrices, according to the co-occurrence index. The largest gaps (as measured by average distances >0.5 between actual and best options) occurred in articles reporting natural resources management as purpose, whereas the smallest were related to marine protected areas management and payments for ecosystem services. The gaps were due to departures in different individual variables. For example, in the case of marine spatial planning the omission of tradeoffs, scenario analysis, multiple scales, and threshold analyses explained the gap, whereas in vulnerability and risk assessment the omission of thresholds, the lack of consistency of the indicators used, and the absence of a definition of ESs explained the gap. We trust that this study will help to recognize that ESs mapping studies should be guided by the purpose of a given intervention rather than by the technical capacities and disciplines of the researchers, if the ESs approach expects to reach a real impact into public policies.

    Waist circumference percentiles in children and adolescents between 6 and 14 years from Santiago, Chile
    (2012) Avalos, C.; Diaz, C.; Martinez, A.; Bancalari, R.; Zamorano, J.; Harbin, F.; Cerda, V.; Fernandez, M.; Cavada, G.; Arteaga, J.; Valenzuela, M.; Toro, M.; Garcia, H.
    Objective: To describe the percentile distribution of waist circumference (WC) by sex and age in a representative sample of children and adolescents of lower-middle and low socioeconomic status in Santiago, Chile. Methods: A cross-section of 3022 primary-school students between the ages of 6 and 14 from middle-low and low-class schools of Santiago. Ten schools from the Primary Education Society (SIP) in Santiago, Chile, were selected at random. WC was measured under standardized procedures as instructed by the WHO (midpoint between lower costal margin and iliac crest). The population was categorized between percentiles 10 and 90 and divided by sex and age. Results: WC tends to increase with age in both males and females, but no significant differences were found in the percentiles by age for boys and girls at any age range (. p>. 0.05). In our sample, comparing Chilean children with other populations (British, Australian, European-American, African-American, Mexican - American and Colo
