Investigating the Species Relationships in Megistostegium ( Malvaceae )
@inproceedings{Shimu2017InvestigatingTS, title={Investigating the Species Relationships in Megistostegium ( Malvaceae )}, author={Tahsina A. Shimu}, year={2017} }
The island of Madagascar is known for its rich fauna and flora, and is an ideal area to study species and speciation (Vences et al., 2009), especially species in the Hibiscus tribe (Koopman & Baum, 2008). The island contains unparalleled levels of endemism and species diversity, making it one of the greatest biodiversity hotspots in the world (Goodman & Benstead, 2005). The three morphologically distinct plant species in the genus Megistostegium will be used to study speciation. Previous…

The accessions of Megistostegium are assigned to three distinct clusters that differ dramatically in habit, leaf size and shape, flower size and morphology, which correspond to the three traditionally delimited species and these morphological boundaries appear to be maintained despite gene flow.

While phylogenetic signal is confounded by hybridization and perhaps incomplete lineage sorting, the three Megistostegium species have meaningful, if incomplete, genetic distinctiveness, according to the GSI and autocorrelation tests.

Biodiversity information presented in the volume is summarized by providing revised estimates of species richness, endemism, and state of knowledge of a wide variety of taxonomic groups occurring on the island.

The first phylogeny that includes complete taxonomic sampling for the Uroplatus leaf-tailed geckos is presented, and is based on morphology and molecular data, and finds both conserved and divergent niches between sister species.

Abstract Madagascar is renowned not only for its high biodiversity and high degree of endemism, but also for ongoing loss of the original primary vegetation. Here we draw attention to the critical…
PyRAD: assembly of de novo RADseq loci for phylogenetic analyses
- BiologybioRxiv
- 2013
It is shown through re-analysis of an empirical RADseq data set that indels are a common feature of such data, even at shallow phylogenetic scales, as well as an optional hierarchical clustering method which allow it to rapidly assemble phylogenetic data sets with hundreds of sampled individuals.

- BiologyPloS one

This modified RADseq approach requires no prior genomic knowledge and achieves per-site and per-individual costs below that of current SNP chip technology, while requiring similar hands-on time investment, comparable amounts of input DNA, and downstream analysis times on the order of hours.

An analysis of watersheds in the context of Quaternary climatic shifts provides a new mechanistic model to explain the process of explosive speciation on Madagascar and provides a framework for biogeographic and phylogeographic studies, as well as a basis for prioritizing conservation actions of the remaining natural forest habitats on the island.
