Evolutionary diversifications of plants on the Qinghai-Tibetan Plateau
Frontiers in Genetics, 2014 The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic and ecological studies support plant diversifications on the QTP through multiple mechanisms such as allopatric ...

Unnoticed in the tropics: phylogenomic resolution of the poorly known arachnid order Ricinulei (Arachnida) [PDF]
Royal Society Open Science, 2015 Ricinulei are among the most obscure and cryptic arachnid orders, constituting a micro-diverse group with extreme endemism. The 76 extant species described to date are grouped in three genera: Ricinoides, from tropical Western and Central Africa, and the

Vicarious goal satiation [PDF]
Journal of Experimental Social Psychology, 2011 A signature feature of self-regulation is that once a goal is satiated, it becomes deactivated, thereby allowing people to engage in new pursuits. The present experiments provide evidence for vicarious goal satiation, a novel phenomenon in which individuals experience "post-completion goal satiation" as a result of unwittingly taking on another person ...

Journal of Systematics and Evolution, EarlyView.Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

The dispersal versus vicariance debate in biogeography
, 1983 Wild’s 1964 study of the Chimanimani Mountain endemics is taken as an example of a vicariance model: endemics (1) are seen to have originated in situ from a residual fragment of an ancestral, once-continuous flora; (2) are held to present in themselves ...

Zoologica Scripta, EarlyView.ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

On the Origin of the Tingidae (Insecta, Heteroptera)
Zoologica Scripta, EarlyView.ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

Tectonic calibrations in molecular dating
Current Zoology, 2011 Molecular dating techniques require the use of calibrations, which are usually fossil or geological vicariance-based. Fossil calibrations have been criticised because they result only in minimum age estimates.

European Journal of Taxonomy, 2016 When based on phylogenetic proposals, biogeographic historic narratives have a great interest for hypothesizing paths of origin of the current biodiversity.

Zoologica Scripta, EarlyView.ABSTRACT Loricariidae is the most diverse catfish family in the Neotropics. Within this group, the genus Spectracanthicus presents conflicting phylogenetic signals: morphological studies suggest monophyly, whereas previous molecular analyses often yield unresolved relationships and taxonomic uncertainty.
