Genetic structure of the saxicole Pitcairnia geyskesii (Bromeliaceae) on inselbergs in French Guiana.
TLDR
High genetic diversity within inselbergs appears as a consequence of the association of genet longevity induced by clonal replication and recruitment of new genets produced by sexual reproduction. Expand
A gleam in the dark: phylogenetic species delimitation in the confusing spring-snail genus Bythinella Moquin-Tandon, 1856 (Gastropoda: Rissooidea: Amnicolidae).
TLDR
The results strongly suggest that classical morphological descriptors may not constitute valid specific criteria within Bythinella, and support a complex scenario of invasions of subterranean habitats, as illustrated by the syntopy of several mitochondrial lineages or the conflicting evolutionary histories between COI and ITS1 in caves. Expand
Molecular phylogenies support multiple morphological reductions in the liverwort subclass Marchantiidae (Bryophyta).
TLDR
The molecular and the combined data both indicate unequivocally that Sphaerocarpales and Monocleales are nested within Marchantiales, and this result is not explicitly refuted by the morphological data. Expand
The leafy liverwortPorella baueri (Porellaceae) is an allopolyploid
TLDR
The discovery of this new, allopolyploid species suggests that hybridization is an important evolutionary process in liverworts, and is likely to be an interspecific hybrid between P. platyphylla and P. cordaeana. Expand
Species Delimitation In The Genus Bythinella (Mollusca: Caenogastropoda: Rissooidea): A First Attempt Combining Molecular And Morphometrical Data
TLDR
The number of species of Bythinella recognized in the Pyrenees appears probably overestimated, and the characters traditionally used for species delimitation should be re-evaluated. Expand
Genetic structure of the xerophilous bromeliad Pitcairnia geyskesii on inselbergs in French Guiana – a test of the forest refuge hypothesis
Inselbergs are isolated granitic rock outcrops that provide distinctive ecological conditions. In northern South America they rise above the surrounding rainforest. Among inselberg specialists,Expand
Molecular phylogeny in mytilids supports the wooden steps to deep-sea vents hypothesis.
TLDR
This study supported the 'wooden steps to deep-sea vent' hypothesis: one of the sunken-wood species had a basal position within the Bathymodiolionae, and all described vent and seep mussels included in the authors' analyses were derived taxa within B Kathymodiolinae. Expand
Genetic relationships between marine and marginal-marine populations of Cerithium species from the Mediterranean Sea
TLDR
Results of isozyme electrophoresis were used to explore the genetic relationships between several Mediterranean morphs of Cerithium, finding that a high larval dispersal capability (via planktotrophy) allows a high gene flow between populations of C. vulgatum. Expand
Genetic variation in a network of natural and reintroduced populations of Griffon vulture (Gyps fulvus) in Europe
TLDR
This study analyzed genetic data from a network of native and reintroduced Griffon vulture populations successfully restored in Southern Europe to assess the level of fragmentation among native populations, the effectiveness of random choice of founders to retain genetic variability of the species, and the loss of genetic diversity in the reintroduced population.
