Tipo: Capítulo de libro
Lugar(es) de estudio: Golfo de California
Resumen: "Mexico is home to a broad biodiversity of shark species, and more than half of the sharks
in Mexican waters are distributed in the Mexican Pacific, with over 62 species recorded.
This high biodiversity is the result of numerous and diverse marine and coastal environments,
including the dynamic Mexican seas, where circulation and spatial variation of
oceanic currents is complex, and the seasonal variation of isotherms can be substantial.
In the Mexican Pacific we can distinguish some patterns of species distribution, with
temperate water and subtropical species found in the northern regions, and tropical
conditions and species found in the south. Due to the blending of cold and warm
waters, however, we can find a mixture of subtropical and tropical sharks in northern
regions seasonally, off the west coast of the Baja California Peninsula and in the Gulf
of California, and these areas contain the highest shark species richness. In this chapter
we described the shark species biodiversity occurring in the Mexican Pacific, review
their conservation status in a regional and global context, and summarize the main
conservation measures and issues associated with their management."
