Map of study area divided in 14 ecoregions, four provinces and two realms.
Abbreviation are in brackets. Ecoregions: 1 = Northern California (NCa), 2 = Southern California Bight (SCB), 3 = Magdalena Transition (MaT), 4 = Cortezian (Cor), 5 = Revillagigedos (Rev), 6 = Mexican Tropical Pacific (MTP), 7 = Chiapas-Nicaragua (CNi), 8 = Nicoya (Nic), 9 = Coco Island (CIs), 10 = Panama Bight (PaB),11 = Guayaquil (Gua), 12 = Northern Galapagos Islands (NGI), 13 = Western Galapagos Islands (WGI), 14 = Eastern Galapagos Islands (EGI). Provinces: Cold Temperate Northeast Pacific (CTNP; blue), Warm Temperate Northeast Pacific (WTNP; purple), Tropical East Pacific (TEaP; green), Galapagos (Gala; red). Realms: Temperate Northern Pacific (TNP; 1–4) and Eastern Tropical Pacific (ETP; 5–14). DOI: dx.doi.org/10.17504/protocols.io.sa5eag6.

Sampled-based rarefaction curves of observed (Sobs) and expected gobies species richness.
Expected richness estimated by non-parametric procedures (Chao 2, Jackknife 1, Jackknife 2 and Incidence Coverage Estimator (ICE). Curves were constructed with 10,000 non-replacement randomizations. DOI: dx.doi.org/10.17504/protocols.io.sbdeai6.
Fig 3.
PCO plot based on gobies fish incidence data.
All marine ecoregions and provinces were grouped sensu Spalding et al. [35]. Jaccard similarity was used as a resemblance measure of species composition. Ecoregions and provinces abbreviations are shown in Fig 1. DOI: dx.doi.org/10.17504/protocols.io.sbceaiw.
