Canary (Serinus canarius) is one of the most beautiful cage birds. They are small and delicate songbird species. Their origin is the Canary Islands in the Atlantic Ocean. They were first brought to Europe by the Spanish sailors in 1478. Than Britain, Germany, France, Netherlands and Italy were started professional canary breeding. The wild ones live in flocks, mostly on the edge of wooded lakes and creeks. While the color of canaries grown in cages is completely yellow, the wild ones are gray-green. Sound in the wild canary is stronger and more impressive. There are 3 types of canaries commonly produced. These are “Song canaries”, “Color canaries” and “Form canaries”. Nowadays they are often produced for their beautiful color and sound. This article gives brief information about canaries and to provide resources to enthusiasts who want to do produce has been prepared.

AbstractExtensive offshore meadows ofHalimeda incrassataare documented for the first time in sandy bottoms of La Palma, Canary Islands.Halimeda incrassataforms dense sublittoral assemblages between 20 and 55 m, but isolated populations occur down to 65 m depth. This species currently spreads over an area of 9.14 ha. Population coverage varies with depth, with the highest values at 35–40 m and an average cover of 62.34%. The calcified segments ofH. incrassataact as a stable substratum in these soft bottoms for the growth of other macroalgae, such as the rhodophytesLophocladia trichocladosandCottoniella filamentosa. Specimens reach lengths of up to 10 cm, shorter than individuals from the Caribbean. Although it is difficult to ascertain whether this species is a recent introduction, there is evidence of a correlation between the increase in population coverage and recent ocean warming, constituting another example of the tropicalization of the marine flora of this region.

Fossil Data

ABSTRACT Bats are one of the most abundant and important mammals in ecosystems. However, their fossil record is scarce and fragile, making them difficult to find. Accordingly, there is no record of this group in the volcanic islands of the mid-Atlantic Ocean apart from the Canary Islands. This paper studies the first bat fossil record of the Canary Islands (Spain). The material studied is found within two Quaternary lava tubes, Cueva de los Verdes on Lanzarote and Cueva Roja on the island of El Hierro. The dental and humeral morphology and biometry are analysed and compared with current specimens. Among our results we highlight the first fossil data of two species endemic to the islands of the mid-Atlantic Ocean, Plecotus teneriffae and Pipistrellus maderensis, the former from the Canary Islands and the latter from the Azores, Madeira and the Canary Islands. We also confirm the presence of Pipistrellus kuhlii in the fossil record of the island of Lanzarote. No differences are observed between the dental morphology of the current and the fossil populations of P. maderensis and Pl. teneriffae. In the case of P. kuhlii, the populations of the Canary Islands and the Iberian Peninsula show differences in the paraconule with respect to the populations from central Europe. Palaeoecological studies of these taxa suggest that these islands presented a similar habitat when the sites were formed to the present-day habitat.

‘The Enemy Within’ begins with volcanic super-eruptions and their devastating consequences such as the 1815 eruption of volcano Tambora in Indonesia, and ancient eruptions in Yellowstone, USA, and Toba, northern Sumatra. Volcanic explositivity index, eruption magnitude, and eruption intensity are explained. Volcanic landslides in Hawaii and the Canary Islands will, in the future, result in giant tsunamis wreaking havoc around the Pacific and Atlantic Ocean rims. But when will they happen? Finally, the fate of industrial cities, such as Tokyo, located near active fault-lines and in earthquake zone, and the resultant effects on the world economy are considered.

AbstractUnderstanding late Holocene extinctions on islands requires accurate chronologies for all relevant events, including multiple colonisations by humans and the introduction of alien species. The most widely held hypothesis on the causes of Holocene island vertebrate extinctions incorporates human impacts, although climatic-related hypotheses cannot be excluded. Both hypotheses have been suggested to account for the extinction of the endemic Lava Mouse,Malpaisomys insularisfrom the Canary Islands. Here we present the first accelerator mass spectrometer (AMS)14C ages from collagen ofM. insularisbones from ancient owl pellets collected at Fuerteventura (Canary Islands, eastern Atlantic Ocean). These new dates contribute to an understanding of the extinction of this species. We are able to exclude climatic causes, predation by invasive species, and competition with the house mouse,Mus musculus. The arrival of Europeans in the Canary Islands correlates with the extinction ofMalpaisomys. The introduction of rats,Rattusspp., together with their parasites and diseases, emerges as the most reasonable hypothesis explaining the extinction ofM. insularis.

Background – Species of Agave and Furcraea (Agavaceae, Asparagaceae s. lat.) are widely cultivated as ornamentals in Mediterranean climates. An increasing number is escaping and naturalising, also in natural habitats in the Canary Islands (Spain). However, a detailed treatment of variously naturalised and invasive species found in the wild in the Canary Islands is not available and, as a result, species identification is often problematic.Methods – The present study is based on many years of fieldwork on the islands of Fuerteventura, Gran Canaria, Lanzarote and Tenerife. Results – Fourteen species and several additional infraspecific taxa of Agave have been identified. In addition to the widely naturalised and invasive Agave americana, A. fourcroydes and A. sisalana (incl. the not previously reported var. armata), the following species of Agave were observed: A. angustifolia (incl. var. marginata), A. attenuata, A. filifera, A. franzosinii, A. lechuguilla, A. macroacantha, A. murpheyi, A. oteroi, A. salmiana (var. ferox and var. salmiana), A. aff. tequilana and A. vivipara. From the genus Furcraea three species were found: F. foetida, F. hexapetala and F. selloana. Several of these newly detected species of Agave and Furcraea are at least locally naturalised. A key for the identification of the representatives of these genera in the study area is presented and all species are illustrated. Additional nomenclatural, taxonomic and ecological notes are also provided.
