background: free-living amoebae (fla) are protozoa that are widely distributed in the environment mainly in water and soil related habitats. thermophilic amoebae are among the most common fla in water bodies, being vermamoeba vermiformis one of the most common species reported worldwide from these sources. interestingly, v. vermiformis has often been reported to survive at high temperatures and...

Fossil bone collagen C dating and δC and δN isotopic measurements of the rodent Canariomys bravoi from Tenerife (Canary Islands, Spain) were used to test two different hypotheses about the causes of extinctions of endemic vertebrates on islands, climate versus humans. For the Tenerife giant rat, we show that it survived the climatic change that occurred between the Middle and Late Holocene, but...
We use data from the Tenerife 10, 15 and 33 GHz beamswitching experiments along with the COBE 53 and 90 GHz data to separate the cosmic microwave background (CMB) signal from the Galactic signal and create two maps at high Galactic latitude. The new multi-MEM technique is used to obtain the best reconstruction of the two channels. The two maps are presented and known features are identified wit...
BACKGROUND, AIM AND SCOPE Ambient air concentrations of polycyclic aromatic hydrocarbons (PAH) were determined at five elevated mountain sites on the European continent and the Atlantic Ocean. All sites can be considered remote background areas since they are situated above the timberline and they lack local emission sources of these compounds. RESULTS AND DISCUSSION Average gas phase concent...
Diversification between islands and ecological radiation within islands are postulated to have occurred in the Euphorbia species (sect. Aphyllis subsect. Macaronesicae) on the Canary Islands. In this study, the biogeographical pattern of 11 species of subsect. Macaronesicae and the genetic differentiation among five species were investigated to distinguish the potential mode and mechanism of di...
