The morphology and phylogeny of anther smut specimens on Tractema verna collected in the United Kingdom were investigated using light microscopy, scanning electron microscopy and partial rDNA sequence analyses. The anther smut of Tractema verna shows similarity to Antherospora eucomis, A. scillae, A. tourneuxii, A. urgineae, A. vaillantii, and A. vindobonensis but differs in spore size range, s...

Metagenomic approaches are rapidly expanding our knowledge of the diversity of viruses. In the fecal matter of Nigerian chimpanzees we recovered three gokushovirus genomes, one circular replication-associated protein encoding single-stranded DNA virus (CRESS), and a CRESS DNA molecule.

To my wife Jane, my mother Verna, and my father Peter. Without my family anything that I achieve is meaningless.

We developed eight polymorphic microsatellite loci for Collinsia verna (Veronicaceae). In a sample of 18–35 individuals from a single population, we found two to 15 alleles per locus (mean 8.3). We also tested these loci for cross-amplification in all 22 species in the tribe Collinseae. Overall, more than half the species in the tribe amplified one microsatellite while three species most closel...

Land-cover change is a major component of global change (Foley et al., 2005). Many forms of land-cover change, such as deforestation and urbanization, are directly associated with land use. Other land-cover changes, such as melting of permafrost, may be indirectly associated with human activity via anthropogenically induced climate change. Further changes in land cover, such as the expansion of...

New voice services are investigated in the fields of Internet telephony (SIP – Session Initiation Protocol) and interactive voice systems (VoiceXML – Voice Extended Markup Language). It is explained how CRESS (Chisel Representation Employing Systematic Specification) can graphically represent services and features in these domains. CRESS is a front-end for detecting feature interactions and for...

A phytochemical investigation of the flowers and leaves of Ficaria verna Huds. (Ranunculaceae) yielded four additional known flavonoid compounds including: kaempferol 3-O-beta-D-(6"-a-L-rhamnopyranosyl)-glucopyranoside (nicotiflorin), apigenin 8-C-beta-D-glucopyranoside (vitexin), luteolin 8-C-beta-D-glucopyranoside (orientin) and apigenin 8-C-beta-D-(2"-O-beta-D-glucopyranosyl)-glucopyranoside...
