Speciation dynamics : contrasts between plants and animals

Speciation, the process leading to the emergence of reproductively isolated species through the accumulation of genetic reproductive barriers, has been a subject of study since textit{the origin of species} and remains an active topic of research. One primary goal of these studies is to elucidate which microevolutionary processes shape the dynamics...

Diversification and introgression in four chromosomal taxa of the Pearson's horseshoe bat (Rhinolophus pearsoni) group.

Published in Molecular phylogenetics and evolution

Chromosomal variation among closely related taxa is common in both plants and animals, and can reduce rates of introgression as well as promote reproductive isolation and speciation. In mammals, studies relating introgression to chromosomal variation have tended to focus on a few model systems and typically characterized levels of introgression usi...

Genetic architecture of a pollinator shift and its fate in secondary hybrid zones of two Petunia species

Published in BMC Biology

Background Theory suggests that the genetic architecture of traits under divergent natural selection influences how easily reproductive barriers evolve and are maintained between species. Divergently selected traits with a simple genetic architecture (few loci with major phenotypic effects) should facilitate the establishment and maintenance of rep...

Spiranthes hachijoensis (Orchidaceae), a new species within the S. sinensis species complex in Japan, based on morpholog...

Published in Journal of Plant Research

The systematics of the Old World Spiranthes sinensis (Pers.) Ames species complex (Orchidaceae) has been complicated by its wide distribution and morphological variations. Within the species complex, S. australis Lindl. has been generally accepted as the only Spiranthes Rich. species distributed on the Japanese mainland. The present study provides ...

Comparative reproductive biology of two sympatric Hypostomus in a Neotropical river.

Published in Zoology (Jena, Germany)

Congeneric species often coexist in sympatry using behavioral and morphological adaptations to reduce competition and interspecific interference, but reproductive patterns behind coexistence remain unknown. We analyzed the gonadal morphology and development, reproductive cycle, and population structure of two sympatric congeneric fishes to evaluate...

How common is hybridization in birds?

Hybridization—the interbreeding of different species—plays an integral role in the evolution of numerous bird species. However, it remains unclear how widespread this phenomenon is within and across different bird groups. Estimating the incidence of hybridization in different bird lineages can inform comparative analyses to uncover the evolutionary...

Integrative characterization of genetic and phenotypic differentiation in an ant species complex with strong hierarchica...

Published in Heredity

Low dispersal, occurrence of asexual reproduction and geographic discontinuity increase genetic differentiation between populations, which ultimately can lead to speciation. In this work, we used a multidisciplinary framework to characterize the genetic and phenotypic differentiation between and within two cryptic ant species with restricted disper...
