Contents covered in the session 13 (21/01/2010) Fauna Biodiversity and Classification.
The UN has declared 2010 as International Year of Biodiversity. " For this reason we initiated the first in a series of presentations where we discuss the biodiversity that surrounds us.
As should be somewhere First, it seems appropriate to do so seeing some of taxonomy. Taxonomy is the science which directs the agencies in a classification system in which the taxa, they work like "boxes" where we introduce groups according to their kinship. So we put in the same drawer organisms that resemble each other, and less with which we put in another drawer. But they are similar? On the flight?, In your way?, ... What are the criteria by which we decide that a species is similar to another?. The taxonomic order according to criteria of phylogenetic affinity, ie, are more like the less time they ceased to be the same "species." Thus, gorillas, chimpanzees and humans, we imagine the same group of hominids. All this group shares many characteristics. For example, a single dental formula (32: I2 / 2 C1 / 1, P2 / 2 M3 / 3) which indicates the high degree of relationship between all groups and the lack of evolutionary drift have suffered.
From a historical perspective of the classifications, we walk through Ancient Greece to see the "animals with blood 'and' animals without blood", the two boxes where they kept all the known fauna. Then in the Middle Ages, were animals "useful", "dangerous" and superfluous. " And, finally, the arrival of Linnaeus in the eighteenth century brought some order to this mess.
Wittaker (1969) with 5-kingdom classification proposed by the foundation of modern taxonomy.
The Animal Kingdom is one of them.
And finally, a quick look at the major invertebrate groups, puts an aside, to a second delivery on biodiversity. But that is another day.
Nature in Almeria. The proximity to the first exit "long" proposes an approach to the natural reality of the neighboring province of Almeria.
The famous beaches of Almeria may distort somewhat the general idea that we all of which happens to be one of the most mountainous provinces in Spain. Many peaks exceed an altitude of 2,000 meters (Chullo, Mortar, The Peppers, Calar Alto, Tetica of Bacares or Mary) in 9 mountain ranges, and is endorsed.
With three national parks, four natural sites and two nature reserves, we find a variety of environments like no other place on our peninsula, from desert to high mountain Tabernas Sierra Nevada, in just a few kilometers.
The village of the thousands (3,000 BC) is named after a distinctive culture that swept through Andalusia, reaching Murcia and southern Portugal.
But if we were to stay with us a feature that particularize this corner of the peninsula, the dryness would own most characteristic trait.
Thus we find the Tabernas Desert, the only desert, technically, the European continent.
the susceptibility of crops, the use of timber, mining and the conditions of torrential rains have led to the current landscape of Almeria.
However, Almeria is the natural jewel of the Old Continent, the European Capital of biodiversity. The causes are found in its geographical location, proximity to Africa, climate and topography. This "jewel" particularize talking about the giant geode Pulpí, a mineral giant gypsum crystals in some cases reaching up to 2m long.
flora and fauna we left for our future visit.
