Senecio gallicus


Senecio gallicus, an annual plant of the genus Senecio and family Asteraceae, is a species that colonizes isolated habitats with difficult environmental conditions. It is widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. S. gallicus is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.

Description

Senecio gallicus has had more phylogenetic description because it is an exceptional species among halotypes with a known intraspecific phylogeographic structure which is also species specific.
Comparisons of allozyme and chloroplast variation in this species indicate that it persisted in Pleistocene coastal refugia during glaciation periods.
;The Endangered One: Senecio alboranicus, or azuzón de Alborán, is reported to be endemic to and critically endangered on Isla de Alborán by ICUN. Alborán is 7.1 hectares and by of volcanic extrusion situated from the port of Adra, Almería on the Spanish coast and from the Melilla on the African coast. S. alboranicus is one of the 26 plants, 20 vascular plants and 6 lichen cited as having inhabited the island, although, not all at the same time.
