FIGURE 3 in Larval fish assemblages in nearshore waters of southeast Gulf of California: vertical and temporal patterns
FIGURE 3 | Water temperature and salinity profiles at each sampling site, for each sampled month from September 1994 to June 1995.
FIGURE 5 in Larval fish assemblages in nearshore waters of southeast Gulf of California: vertical and temporal patterns
FIGURE 5 | Correlation triplot of the db-RDA showing the relationship between explanatory (temperature and salinity) and response variables (species). Black labels indicate the position of species in the ordination; their size increase according to the abundance of the species to achieve a better visualization. Samples are coded by depths and months. The angles between species and explanatory variables reflect their correlations; a small angle implies a positive correlation, a large one suggests a negative correlation, and a 90° angle indicates no correlation between two variables.

Data from: Avoided emissions and conservation of scrub mangroves: a potential Blue Carbon project in the Gulf of California, Mexico
Mangroves are considered ideal ecosystems for Blue Carbon projects. However, because of their short stature, some mangroves ("scrub" mangroves, < 2m) do not fulfil the current definition of "forests" which makes them ineligible for emission reduction programs such as REDD+. Short stature mangroves can be the dominant form of mangroves in arid and poor nutrient landscapes, and emissions from their deforestation and degradation could be substantial. Here, we describe a potential Blue Carbon project in the Gulf of California, Mexico, to illustrate that projects which avoid emissions from deforestation and degradation could provide financial resources to protect mangroves that cannot be included in other emission reduction programs. The goal of the project is to protect 16,058 ha of mangroves through conservation concessions from the Mexican Federal Government. The cumulative avoided emissions of the project are 2.84 million Mg CO2 over 100 years, valued at $US 426,000 per year (US$15 per Mg CO2 in the California market). The funds could be used for community-based projects that will improve mangrove management, such as surveillance, eradication of invasive species, rehabilitation after tropical storms, and environmental education. The strong institutional support, secure financial status, community engagement, and clear project boundaries provide favourable conditions to implement this Blue Carbon project. Financial resources from Blue Carbon projects, even in mangroves of short stature, can provide substantial resources to enhance community resilience and mangrove protection.

Data from: Long-term isolation at a low effective population size greatly reduced genetic diversity in Gulf of California fin whales
The Gulf of California, Mexico is home to many cetacean species, including a presumed resident population of fin whales, Balaenoptera physalus. Past studies reported very low levels of genetic diversity among Gulf of California fin whales and a significant level of genetic differentiation from con-specifics in the eastern North Pacific. The aim of the present study was to assess the degree and timing of the isolation of Gulf of California fin whales in a population genetic analysis of 18 nuclear microsatellite genotypes from 402 samples and 565 mitochondrial control region DNA sequences (including mitochondrial sequences retrieved from NCBI). The analyses revealed that the Gulf of California fin whale population was founded ~2.3 thousand years ago and has since remained at a low effective population size (~360) and isolated from the eastern North Pacific (Nem between 0.89–1.4). The low effective population size and high degree of isolation implied that Gulf of California fin whales are vulnerable to the negative effects of genetic drift, human-caused mortality and habitat change.
