Background Callitropsis guadalupensis (Guadalupe cypress) is endemic to Guadalupe Island, Mexico, where it is the dominant species of the only forest. The species has suffered declining numbers following the introduction of goats to the island over 150 years ago. Callitropsis guadalupensis is closely related to Callitropsis forbesii (Tecate cypress), distributed in small isolated populations in mainland Baja California and southern California. The objective of the present study was to compare…

Understanding the genetic diversity of the guayabillo (Psidium galapageium), an endemic plant of the Galapagos Islands

The findings of this study highlight the complex population dynamics that shape the genetic diversity of species like the guayabillo and emphasize the need to explore the currently unresolved questions about this Galapagos endemic plant.

Molecular genetic analysis of two native desert palm genera, Washingtonia and Brahea, from the Baja California Peninsula and Guadalupe Island

Abstract The complex geological and ecological processes that have generated high levels of biodiversity and endemism in the Baja California Peninsula have been the subject of intensive study.

A molecular biogeography of the New World cypresses (Callitropsis, Hesperocyparis; Cupressaceae)

Results presented here suggest ancestral NWC colonized the New World from Asia, perhaps by a more widespread trans-Beringian ancestor, in the late Cretaceous or early Cenozoic.

Museomics illuminate the history of an extinct, paleoendemic plant lineage (Hesperelaea, Oleaceae) known from an 1875 collection from Guadalupe Island, Mexico

It is confirmed that Hesperelaea was a paleoendemic lineage that likely predates Guadalupe Island, and provides a notable example of the high potential of NGS for analyzing historical herbarium specimens and revolutionizing systematics.

Gypsum soil restriction drives genetic differentiation in Fouquieria shrevei (Fouquieriaceae).

It is concluded that genetic drift has been intense and gene flow low in differentiating populations that follow an island-like pattern of gypsum deposits of the deserts of North America.

Genomic Insights into the Historical Population Dynamics and Spatial Differentiation of an Endangered Island Endemic Palm, Brahea edulis

Premise of research. Brahea edulis is an endangered palm endemic to the oceanic island of Guadalupe, Mexico, with a small population of just about 4000 individuals; it was chronically grazed by goats

How Did Fouquieria Come to the Chihuahuan Desert? Phylogenetic and Phylogeographic Studies of Fouquieria shrevei and F. splendens and the Role of Vicariance, Selection, and Genetic Drift

We discuss the radiation and dispersal of Fouquieria, the sole genus of Fouquieriaceae, that includes eleven species, all endemic to the warm deserts and dry subtropical regions of North America. Two

Genetic Diversity and Conservation of Mexican Forest Trees

It is recommended that genetic diversity should be measured across species with an identical type of genetic marker, by surveying similar numbers of loci, individuals and populations, and using identical indices of genetic diversity, relevant to conservation of trees.

El análisis de la genética molecular revela patrones contrastantes de la estructura poblacional, la divergencia mediada ecológicamente y la dispersión a larga distancia en palmeras icónicas de América del Norte

This study used both the classical Sanger sequencing and GBS approaches to provide a genome-wide perspective on the comparative species and population structure of two iconic North American palm genera, Washingtonia and Brahea, on the Baja California peninsula, the adjacent Mexican mainland and Guadalupe Island.

Do island plant populations really have lower genetic variation than mainland populations? Effects of selection and distribution range on genetic diversity estimates

This study suggests that identification and removal of markers potentially affected by selection should be routinely implemented in estimates of GD, particularly if different lineages are compared, and provides compelling evidence that the expectation of low GD cannot be generalized to island plant populations.



Potential refugia in Taiwan revealed by the phylogeographical study of Castanopsis carlesii Hayata (Fagaceae)

This study suggests that two potential refugia existed during the last glaciation of C. carlesii, and estimates of NST–GST for populations on both sides of the CMR indicate that no phylogeographical structure exists.

Ancestry and divergence of subtropical montane forest isolates: molecular biogeography of the genus Abies (Pinaceae) in southern México and Guatemala

Trends suggest that the Mesoamerican Abies share a recent common ancestor and that their divergence and speciation is mainly driven by genetic drift and isolation during the warm interglacial periods.

Postglacial population growth of Cunninghamia konishii (Cupressaceae) inferred from phylogeographical and mismatch analysis of chloroplast DNA variation

Excess in singletons as well as star‐like phylogeny of haplotypes suggested no clearcut migration patterns of C. konishii after glacial maximum, which is supported by the combined results of fossil pollen record, low nucleotide diversity, significant Tajima's d‐value, phylogeographical analysis and unimodal mismatch distribution.

Phylogeography of the Qinghai‐Tibetan Plateau endemic Juniperus przewalskii (Cupressaceae) inferred from chloroplast DNA sequence variation

The contrasting phylogeographic structures of the haplotype‐rich plateau edge area and the almost haplotypes‐uniform plateau platform region indicate that the plateau platform was recolonized by J. przewalskii during the most recent postglacial period, supported by the findings of a nested clade analysis.

Chloroplast DNA transgresses species boundaries and evolves at variable rates in the California closed-cone pines (Pinus radiata, P. muricata, and P. attenuata).

Surprisingly, Montery pine and the southern race of bishop pine were much more similar to one another than was the northern race of Bishop pine to its conspecific intermediate and northern races.

Spatial pattern of chloroplast DNA variation of Cyclobalanopsis glauca in Taiwan and East Asia

The possibility that two types of chloroplast DNA variation in Cyclobalanopsis glauca were colonized northward from the southeastern part of Taiwan is suggested, with a neutrality test suggesting a demographic expansion recovered from a bottleneck.


The only natural population of Guadalupe cypress (Callitropsis guadalupensis) occurs on Guadalupe Island, an oceanic island off the Baja California peninsula. This population has suffered an intense

High genetic divergence characterizes populations of the endemic plant Lithophragma maximum (Saxifragaceae) on San Clemente Island

The results suggest that populations of L. maximum have historically been small and isolated, which is likely due to the rugged habitat in which this species occurs and limited pollen and seed dispersal, and conservation efforts should focus on preserving populations in multiple canyons, maintaining large population sizes to preserve genetic variation.

High population differentiation and genetic variation in the endangered Mexican pine Pinus Rzedowskii (Pinaceae).

A convex relationship between the genetic distance among populations and the number of ancestral lineages is found, suggesting that demographically this species has not been at risk recently.

Allozyme variation in the endangered insular endemic Castilleja grisea.

The observed genetic variation is moderately high, unusually so for an insular endemic species, suggesting that C. grisea may not have lost substantial genetic variation during 150 years of overgrazing, and indicating that it is unlikely to be endangered by genetic factors.
