Deep genealogies and the mid-peninsular seaway of Baja California

Deep genealogical history without population differentiation: discordance between mtDNA and allozyme divergence in the zebra-tailed lizard (Callisaurus draconoides).

The peninsula of Baja California has a complex geological history that has strongly affected the regional biota. Genealogical histories of many species have revealed congruent patterns, which suggest that the peninsula was temporarily submerged at two locations. We sequenced a total of 1953 base pairs (bp) of the mitochondrial genome for 42 specimens of the zebra-tailed lizard (Callisaurus drac...

The Peninsular Effect on Species Diversity and the Biogeography of Baja California

The Endemic Insular and Peninsular Species Chaetodipus spinatus (Mammalia, Heteromyidae) Breaks Patterns for Baja California

The Baja California peninsula is the second longest, most geographically isolated peninsula on Earth. Its physiography and the presence of many surrounding islands has facilitated studies of the underlying patterns and drivers of genetic structuring for a wide spectrum of organisms. Chaetodipus spinatus is endemic to the region and occurs on 12 associated islands, including 10 in the Gulf of Ca...

Cryptic vicariance in the historical assembly of a Baja California peninsular desert biota.

We use analyses of phylogeographic population structure across a suite of 12 mammalian, avian, amphibian, and reptilian species and species-groups to assess the role of Late Miocene to Pleistocene geological history in the evolution of a distinct Baja California Peninsular Desert biota. Comparative examination of phylogroup distributions provides support for previously hypothesized vicariant ev...

Geothermal gradients in continental magmatic arcs: Constraints from the eastern Peninsular Ranges batholith, Baja California, México

In continental arcs the extension of geothermal gradients derived from shallow crustal levels to depth predicts widespread melting at pressures that are inconsistent with seismic studies. Numerical models of low-pressure metamorphism in continental arcs suggest that these extrapolations are problematic because magmatic advection is the dominant mechanism of heat transport in these terranes rath...
