Compared to organelle genomes, the nuclear genome comprises a vast reservoir of genes that potentially harbor phylogenetic signal. Despite the valuable data that sequencing projects of model systems offer, relatively few single-copy nuclear genes are being used in systematics. In part this is due to the challenges inherent in generating orthologous(More)
Among eukaryotes two types of nuclear ribosomal DNA (nrDNA) organization have been observed. Either all components, i.e. the small ribosomal subunit, 5.8S, large ribosomal subunit, and 5S occur tandemly arranged or the 5S rDNA forms a separate cluster of its own. Generalizations based on data derived from just a few model organisms have led to a(More)
PREMISE OF THE STUDY The development of three low-copy nuclear markers for low taxonomic level phylogenies in Asteraceae with emphasis on the subtribe Hieraciinae is reported. METHODS AND RESULTS Marker candidates were selected by comparing a Lactuca complementary DNA (cDNA) library with public DNA sequence databases. Interspecific variation and(More)
Toxoplasma gondii is an obligate intracellular parasite that infects a variety of mammals and birds. T. gondii also causes human toxoplasmosis; although toxoplasmosis is generally a benign disease, ocular, congenital or reactivated disease is associated with high numbers of disabled people. Infection occurs orally through the ingestion of meat containing(More)
Specialization is typically inferred at population and species level but in the last decade many authors highlighted this trait at the individual level, finding that generalist populations can be composed by both generalist and specialist individual. Despite hundreds of reported cases of individual specialization there is a complete lack of information on(More)
This paper outlines a novel methodology for calibrating building energy simulation (BES) models through the use of an evidence-based approach and detailed simulation modelling. The proposed calibration methodology is applied to a 30,000m 2 office building. The case study illustrates the results of calibrating the model to Energy Monitoring System (EMS) and(More)
This paper presents the Key Factors methodology that supports energy managers in determining the optimal building operation strategy in relation to both energy consumption and thermal comfort. The methodology is supported by the utilisation of calibrated building energy simulation models that match measured data gathered by an extensive measurement(More)
Quesnelia is an endemic genus of the Atlantic Forest in Brazil. It features 21 species and three varieties that are distributed from Santa Catarina to Bahia, with diversity centers in the Rio de Janeiro coastal region and the rainforest of southern Bahia. It is divided into the subgenera Quesnelia subg. Quesnelia and Quesnelia subg. Billbergiopsis. In this(More)
