Mediterranean ecosystems present great biodiversity, which may be explained by some of the above. Mediterranean type ecosystems occupy less than 5% of Earthâs surface, but include around 20% of the global flora. In all Mediterranean climate regions, a similar â to a certain degree â vegetation has emerged.This includes woody, evergreen shrubs, with leaves wide, small and hard (sclerophylls), presenting strong characteristics of adaptation to the regionsâ climate.editerranean climate is characterized by wet, mild winters and large, warm, dry summers. Most part of yearly rainfall occurs during the winter and there can be many dry months, with the exception of summer storms. Due to summer drought, wild fires are, also, a Mediterranean climate characteristic.
Sudden cardiac arrest can result from cardiac and non-cardiac causes including the following: Coronary artery disease. Coronary artery disease (CAD), also known as ischemic heart disease, is responsible for 62 to 70 percent of all SCDs. CAD is a much less frequent cause of SCD in people under the age of 40.
Other cardiac abnormalities that can cause sudden death are heart valve abnormalities, electrical conduction abnormalities of the heart, and rupture of the aorta (the large blood vessel that carries the blood from the heart to the body). Another cause of sudden death among athletes is Marfan syndrome (Fig. 2).
