Embracing discordance: Phylogenomic analyses provide evidence for allopolyploidy leading to cryptic diversity in a Mediterranean Campanula (Campanulaceae) clade
The Mediterranean Basin harbors a remarkable amount of biodiversity, a high proportion of which is endemic to this region. Here, we present an in-depth study of an angiosperm species complex, in which cryptic taxonomic diversity has been hypothesized. Specifically, we focus on four currently recognized species in the Roucela complex, a well-supported clade in the Campanulaceae/Campanuloideae: C...

متن کاملExtensive cryptic species diversity and fine-scale endemism in the marine red alga Portieria in the Philippines.
We investigated species diversity and distribution patterns of the marine red alga Portieria in the Philippine archipelago. Species boundaries were tested based on mitochondrial, plastid and nuclear encoded loci, using a general mixed Yule-coalescent (GMYC) model-based approach and a bayesian multilocus species delimitation method. The outcome of the GMYC analysis of the mitochondrial encoded c...
متن کاملDiversity, endemism, and age distributions in macroevolutionary sources and sinks.
Quantitative tests of historical hypotheses are necessary to advance our understanding of biogeographic patterns of species distributions, but direct tests are often hampered by incomplete fossil or historical records. Here we present an alternative approach in which we develop a dynamic model that allows us to test hypotheses about regional rates of taxon origination, extinction, and dispersal...
متن کاملCryptic diversity in intestinal protists.
In the past few years our understanding of genetic variation within and between species of intestinal parasitic protists has changed significantly. New species names have been assigned and others have been dropped in response to new data. In this review, I summarise these findings and discuss their implications for future studies. In several cases the findings suggest that caution needs to be e...
