“…The oceanography of the Gulf of California is extremely complex and local directions of water movement vary with season, thus it is difficult to make specific predictions. But several recent models of Gulf circulation predict that water masses are exchanged between upper and central Gulf gyres (Lavin and Marinone 2003;Makarov and Jiménez-Illescas 2003;Marinone 2003;Gutiérrez et al 2004) and it therefore seems likely that larvae who get offshore and into gyres could also disperse between regions.…”

Abstract. Comparisons across multiple taxa can often clarify the histories of biogeographic regions. In particular, historic barriers to movement should have affected multiple species and, thus, result in a pattern of concordant intraspecific genetic divisions among species. A striking example of such comparative phylogeography is the recent observation that populations of many small mammals and reptiles living on the Baja California peninsula have a large genetic break between northern and southern peninsular populations. In the present study, I demonstrate that five species of near-shore fishes living on the Baja coastline of the Gulf of California share this genetic pattern. The simplest explanation for this concordant genetic division within both terrestrial and marine vertebrates is that the Baja Peninsula was fragmented by a Plio-Pleistocene marine seaway and that this seaway posed a substantial barrier to movement for near-shore fishes. For some fish species, the signal of this vicariance in mtDNA has been eroded by gene flow and is not evident with classic, equilibrium measures of population structure. Yet, significant divisions are apparent in coalescent analyses that jointly estimate divergence with gene flow. The genetic divisions within Gulf of California fishes also coincide with recognized biogeographic regions based on fish community composition and several environmental factors. It is likely that adaptation to regional environments and present-day oceanographic circulation limit gene exchange between biogeographic regions and help maintain evidence of past vicariance.

“…The former study found that significant biological and environmental effects determine to where the larvae will disperse, while the latter showed that dispersal closely followed current patterns. In the Gulf of California, complex seasonal upwellings and various gyres have been shown to disperse particles (and likely gametes and larvae) both north and southward (Marinone 2003; Gutierrez et al 2004; Marinone et al 2009). As directionality of the currents change from a general southward flow in April to northward in June (Marinone et al 2009), the path that larvae in the Gulf of California take likely varies based upon the timing of the spawn and the directionality of the currents.…”

Nuclear and mtDNA lineage diversity in wild and cultured Pacific lion-paw scallop, Nodipecten subnodosus (Baja California Peninsula, Mexico)

2010

Pacific lion-paw scallops were collected from natural aggregations in Laguna Ojo de Liebre (Pacific Ocean), the Gulf of California, and from aquaculture facilities for genetic diversity analyses. Mitochondrial DNA sequencing uncovered two highly supported clades separated by 2.5% divergence. Data from ten microsatellite markers suggest individuals from these mitogroups are introgressed, raising questions about the mitotype origin. Some evidence suggests gene flow between La Paz and Ojo de Liebre; otherwise the Gulf of California and Ojo de Liebre are acting as two distinct populations. It is unclear whether translocations between sites have influenced the observed genetic structure or whether gene flow has been facilitated by past geologic events. Finally, scallops spawned for aquaculture are unique from the wild and have significantly less diversity. These results warrant the attention of managers and producers who should work to monitor and conserve genetic diversity in both wild and aquaculture populations.Electronic supplementary materialThe online version of this article (doi:10.1007/s00227-010-1534-1) contains supplementary material, which is available to authorized users.

“…), a transition zone where different surface water masses converge and the distribution of horizontal and vertical water masses is affected by a number of seasonal and interannual processes (Castro et al ). The Gulf of California Water (GCW) has the highest salinity in the area (≥ 34.9) and a very variable temperature (> 12°C annual range), while the less salty (< 34.9) and relatively warmer Tropical Surface Water (TSW) enters from the Pacific Ocean (Beier ; Lavín and Marinone ; Gutiérrez et al ). The Subtropical Subsurface Water (SSW) is found beneath these surface waters (∼ 70 m depth) characterized by high dissolved inorganic carbon (> 2200 μmol kg −1 ), low temperature and little dissolved oxygen (Hernández‐Ayón et al ; Franco et al ) along with the California Current Water (CCW), which occurs seasonally and is characterized by cold temperature and low salinity levels, but is richer in oxygen than to the other three water masses just mentioned (Castro et al ).…”

Seasonal variations of the CO2 system in seawater for coral reefs are often controlled by both chemical‐biological processes and by regional oceanographic features in combination with the residence time of adjacent water. This study reports the seasonal variability of the CO2 system along a year though dissolved inorganic carbon and pH measurements in Cabo Pulmo, a fringing reef from the Mexican Pacific. Two conditions were found on the reef: summer with the presence of Tropical Surface Water (TSW), characterized by high temperature, lower DIC levels, and a higher aragonite saturation (Ωarag); and winter with Gulf of California Water (GCW), when the opposite occurred. This seasonal variation was due to the horizontal advection of two surface water masses: Gulf of California water during winter and Tropical Surface Water the rest of the year as a result of the ocean circulation at the entrance of the Gulf of California. Therefore, the reef is significantly influenced by open ocean waters, where the depth is less than 20 m. The seasonal variability in Ωarag between months with the presence of GCW and TSW is one of the largest ranges reported in coral reefs (ΔΩarag = 0.5 units). Our results suggest that the reef community cannot modify the aragonite or pH of incoming ocean water. This might be the case in other fringing reefs, where the use of ocean acidification forecast models is suitable.
