Corolla morphology influences diversification rates in bifid toadflaxes (Linaria sect. Versicolores).

BACKGROUND AND AIMS The role of flower specialization in plant speciation and evolution remains controversial. In this study the evolution of flower traits restricting access to pollinators was analysed in the bifid toadflaxes (Linaria sect. Versicolores), a monophyletic group of ~30 species and subspecies with highly specialized corollas. METHODS A time-calibrated phylogeny based on both nuc...

Historical Isolation versus Recent Long-Distance Connections between Europe and Africa in Bifid Toadflaxes (Linaria sect. Versicolores)

BACKGROUND Due to its complex, dynamic and well-known paleogeography, the Mediterranean region provides an ideal framework to study the colonization history of plant lineages. The genus Linaria has its diversity centre in the Mediterranean region, both in Europe and Africa. The last land connection between both continental plates occurred during the Messinian Salinity Crisis, in the late Miocen...

Subgeneric classification of Linaria (Plantaginaceae; Antirrhineae): molecular phylogeny and morphology revisited

Linaria Mill. (Plantaginaceae) with about 160 spp. is the largest genus of the tribe Antirrhineae. We conducted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer region (ITS) and chloroplast DNA (rpl32-trnL) sequence data to test the monophyly of currently recognized sections in Linaria. For this purpose 86 species representing seven sections of Linaria and one species ...

Developmental mode influences diversification in ascidians.

Ascidian species (Tunicata: Ascidiacea) usually have tailed, hatching tadpole larvae. In several lineages, species have evolved larvae that completely lack any tail tissues and are unable to disperse actively. Some tailless species hatch, but some do not hatch before going through metamorphosis. We show here that ascidian species with the highest speciation rates are those with the largest rang...

Mutuality, Diversification and Deposit Rates

There is an increased sophistication in the provision of financial services by UK financial mutuals. This paper presents evidence of a more complex process of price setting by these firms. From a theoretical model of the determination of deposit rates, the rate setting behaviour of firms is estimated empirically. Controlling for different service provision and firm characteristics heterogeneous...
