Greece. The Land of Diversity. by Alexandra Kavvadia https://padlet.com/kavvadia_alexandra/alexandraGR en-us 2019-01-23 18:19:33 UTC 2023-05-09 12:39:31 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Beartoy.png Natural Environment in Greece kavvadia_alexandra https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323613963 Due to the great range of climatic and geomorphologic conditions, species and ecosystems diversity is high. Greece entirely lies in the Mediterranean biogeographical region, with ecosystems ranging from semi-desert and maquis, to cold climate mountain forests of birch, scots pine and spruce. Wetlands (rivers, estuaties, deltas, lagoons, shallow lakes, shallow marine formations, and marshes) cover a relatively wide area (210.000 hectares) and forests cover nearly 30% of the country's territory. 
 About two-thirds of the Greek territory is covered by a hilly or mountainous terrain, with the typical landscape being rugged and steep. Greece has a very extensive coastline of about 15.000 kilometres and about 3.000 islands, which represent 20% of the land area. The coastline is mainly rocky and sandy with about 5% wetlands.

It stretches across all 28 EU countries, both on land and at sea. The aim of the network is to ensure the long-term survival of Europe's most valuable and threatened species and habitats, listed under both the Birds Directive and the Habitats Directive. ]]> 2019-01-23 18:49:12 UTC https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323623672 Conservation and sustainable use of Natura 2000 kavvadia_alexandra https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323626367 Natura 2000 is not a system of strict nature reserves from which all human activities would be excluded. While it includes strictly protected nature reserves, most of the land remains privately owned. The approach to conservation and sustainable use of the Natura 2000 areas is much wider, largely centered on people working with nature rather than against it. However, Member States must ensure that the sites are managed in a sustainable manner, both ecologically and economically. ]]> 2019-01-23 18:53:26 UTC https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323626367 Why is biodiversity important for Greece ? kavvadia_alexandra https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323643816 According  to  the  most  recent  surveys,  Greek  flora  includes  5752  species  and  1893 subspecies of vascular plants, which cumulatively represent 6600 taxa that belong to 1072 genera and 185 families. Greece is also one of the world’s hotspots for endemic plants,  with  1278  endemic  species  (22.2%  of  all  species  present)  and  452  endemic subspecies,  which  cumulatively  represent  1461  taxa  (22.1%  of  all  taxa  present  in Greece).]]> 2019-01-23 19:21:25 UTC https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323643816 What are the main threats to biodiversity? kavvadia_alexandra https://padlet.com/kavvadia_alexandra/alexandraGR/wish/323648500
The direct causes of the loss of biodiversity in Greece:
  • Loss, modification degradation and fragmentation of natural and semi -natural habitats
  • Unsustainable practices used in several types of production activities
  • Climate change
  • Soil, water and air pollution
  • Biological Invasions
  • Forest fires

Example: The diet of the Eleonora's falcon until the end of July, when the egg-laying has been completed, consists mainly of big insects, such as butterflies, flying ants, dragonflies, cicadas and beetles that it catches in the air with its talons, above islands or the sea (Ristow and Wink 1994, Ristow 2001). During the following period and until October, it feeds exclusively on migratory birds, a food source that is, theoretically, infinite. After its breeding, between the end of October and the beginning of November, it flies to East Africa, especially to Madagascar, where it spends the winter, returning to a diet based on insects.

Mediterranean monk seals spend most of their lives at sea looking for food. Recent scientific research has shown that a large part of their diet consist of octopi. Monk seals can travel significant distances at sea in a short time period (i.e., 150 nautical miles in 3 months) and dive to depths down to 200 m starting at a very young age. 
The preferred terrestrial habitat used by monk seals are well-protected marine caves found along remote and inaccessible stretches of coastline. Suitable caves have one or more above-surface or underwater entrances that lead to a main resting area with a beach or a flat, rocky surface. According to the information currently available, monk seals in Greece use the caves mainly at night, and cave usage increases significantly during the pupping season and in the winter. During the first months of their lives, young monk seal pups spend a lot of time on the beach or in the water inside the cave. Monk seal survival seems to be very dependent on the existence of suitable pupping caves.

    Directive 92/43/EEC (EEC, 1992).
    Among the threats identified in the review of Basso et al. (2015) for the already endangered populations of P. nobilis, they included contaminants, invasive species, the climate change and mainly the degradation of Posidonia meadows.
    Haplosporidan parasites have been detected infecting species of bivalves, gastropods, crustacean, worms, ascidians and even hyperparasiting trematode larvae (reviewed by Burreson and Ford (2004) and Arzul and Carnegie (2015)), but until recently they were never reported in a member of Pinnoidea Superfamily.
    In the Greek seas the massive mortality of the Pina population began to be observed this summer. In areas of the northern Aegean, more than 90% of the population has already been destroyed, while reports of mass mortality are found in many other regions of Greece. Fortunately, so far is still healthy populations of the species in the northern Dodecanese.
    Although the appearance of Haplosporidum pinnae has not yet been identified, it is believed that the presence of some alien species may transmit the parasite to the water. Pina does not have any physical protection against it, so it is fully exposed to this parasite.]]>     2019-02-11 09:39:30 UTC https://padlet.com/kavvadia_alexandra/alexandraGR/wish/329773669     Predator - prey relation kavvadia_alexandra https://padlet.com/kavvadia_alexandra/alexandraGR/wish/329782258 Carnivores - herbivores
