Cabo de Gata-Níjar Natural Park Many species of lark live on the steppe, including the rare Dupont's lark ("Chersophilus duponti") and there are also little bustards ("Tetrax tetrax") and stone curlews ("Burhinus oedicnemus"). Sea birds include yellow-legged gulls ("Larus michahellis"), terns, razorbills ("Alca torda"), shags, the occasional puffin ("Fratercula arctica") and Cory's ("Calonectris diomedea") and Balearic shearwaters ("Puffinus mauretanicus"). The wealth of animal life provides prey for a number of raptors: ospreys ("Pandion haliaetus"), peregrine falcons ("Falco peregrinus"), kestrels ("Falco tinnunculus"), and eagles. Approximately 15 species of reptile are found in the park, including Italian wall lizards ("Podarcis sicula"), ocellated lizards ("Timon lepidus"), grass snakes
Porphyria cutanea tarda the body. Certain mutations in the "HFE" gene cause hemochromatosis (an iron overload disorder). People who have these mutations are also at an increased risk of developing porphyria cutanea tarda. In the 20% of cases where porphyria cutanea tarda is inherited, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene is sufficient to decrease enzyme activity and cause the signs and symptoms of the disorder. While inherited deficiencies in uroporphyrinogen decarboxylase often lead to the development of PCT, there are a number of risk factors that can both cause and exacerbate the symptoms
