Sharpening the species boundaries in the Cladonia mediterranea complex (Cladoniaceae, Ascomycota)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Pino-Bodas, R.; Pérez-Vargas, I.; Stenroos, S.; Ahti, T.; Burgaz, A.R.
The complex Cladonia mediterranea belongs to the section Impexae and is formed by C. azorica, C. macaronesica and C. mediterranea. These species are basically distributed in the Mediterranean and Macaronesian Regions. In the present work the limits between the species of this complex are re-examined. To this end, the morphological characters were studied along with the secondary metabolites and the DNA sequences from three loci (ITS rDNA, IGS rDNA and rpb2). The morphological data were studied by principal component analysis (PCA), while the DNA sequences were analyzed using several approaches available to delimit species: genealogical concordance phylogenetic species recognition, species tree (BEAST* and spedeSTEM) and cohesion species recognition. In...

Molecular evidence for the polyphyly of Bostryx (Gastropoda: Bulimulidae) and genetic diversity of Bostryx aguilari
Provedor de dados: Revista Brasileira de Zoologia
Autores: Ramirez,Jorge L.; Ramírez,Rina.
Bostryx is largely distributed in Andean Valleys and Lomas formations along the coast of Peru and Chile. One species, Bostryx aguilari, is restricted to Lomas formations located in the Department of Lima (Peru). The use of genetic information has become essential in phylogenetic and population studies with conservation purposes. Considering the rapid degradation of desert ecosystems, which threatens the survival of vulnerable species, the aim of this study was, first, to resolve evolutionary relationships within Bostryx and to determine the position of Bostryx within the Bulimulidae, and second, to survey the genetic diversity of Bostryx aguilari, a species considered rare. Sequences of the mitochondrial 16S rRNA and nuclear rRNA regions were obtained for...
