Clades, Clocks, and Continents: Historical and Biogeographical Analysis of Myrtaceae, Vochysiaceae, and Relatives in the Southern Hemisphere
TLDR
The results indicate that the PHMV differentiated during the late Cretaceous, which is likely in explaining the South American–Australasian disjunction and subsequent dispersal events between the two and to Africa and the Mediterranean basin.
Aligning Conservation Priorities Across Taxa in Madagascar with High-Resolution Planning Tools
TLDR
It is shown, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species.
Urticalean rosids: circumscription, rosid ancestry, and phylogenetics based on rbcL, trnL-F, and ndhF sequences.
TLDR
To address the composition of the urticalean rosids, the relationships of the component families and analyze evolution of morphological characters, sequence variation is analyzed for a large sampling of these families and various rosid outgroups using rbcL, trnL-F, and ndhF plastid regions.
A molecular phylogeny and classification of Bignoniaceae.
TLDR
Parsimony inference suggests that the family originated in the neotropics, with at least five dispersal events leading to the Old World representatives.
MOLECULAR EVOLUTION, ADAPTIVE RADIATION, AND GEOGRAPHIC DIVERSIFICATION IN THE AMPHIATLANTIC FAMILY RAPATEACEAE: EVIDENCE FROM ndhF SEQUENCES AND MORPHOLOGY
Abstract Rapateaceae (16 genera, ∼100 species) is largely restricted to the tepuis and sandplains of the Guayana Shield in northern South America, with Maschalocephalus endemic to West Africa. The
MOLECULAR EVOLUTION, ADAPTIVE RADIATION, AND GEOGRAPHIC DIVERSIFICATION IN THE AMPHIATLANTIC FAMILY RAPATEACEAE: EVIDENCE FROM ndhF SEQUENCES AND MORPHOLOGY
TLDR
A molecular phylogeny for representatives of 14 genera, based on sequence variation in the chloroplast‐encoded ndhF gene, suggests that infrequent long‐distance dispersal combined with vicariance accounts for speciation atop tepuis in the Stegolepis alliance.
Addressing data deficiency in classifying extinction risk: a case study of a radiation of Bignoniaceae from Madagascar.
TLDR
Among the species threatened with extinction, six of them were "rescued" from the data-deficient category by considering both the sample dates and localities of places where they occurred in relation to additional collections that took place in the immediate area.
When Flowers Smell Fermented: The Chemistry and Ontogeny of Yeasty Floral Scent in Pawpaw (Asimina triloba: Annonaceae)
TLDR
The yeasty odor of A. triloba is unusual in angiosperms and may serve to attract novel fly and beetle pollinators.
Hydration changes in cadaver eyes prepared for practice and experimental surgery.
TLDR
Hyperosmolar solutions were more efficient than pressure gradients in thinning the cadaver central cornea and hydration shifts of the de-epithelialized cornea were dramatic with use of Balanced Salt Solution drops or drying and were minimized with useof hyperosmolars topical solutions.
Delimitation of Malagasy tribe Coleeae and implications for fruit evolution in Bignoniaceae inferred from a chloroplast DNA phylogeny
TLDR
A phylogeny based on three chloroplast regions identifies a monophyletic Coleeae that is endemic to Madagascar and surrounding islands of the Indian Ocean (Seychelles, Comores and Mascarenes).
