Resumen
[ENG] Anthemis chrysantha (Asteraceae) is a winter annual plant with erect habit which reaches a height of 30 cm. Its emergence period begins in autumn, flowering occurs from early March to late May, and fruits mature mostly in June, after that the plant dies. This species is endemic to North Africa and Cartagena (Murcia, southeast of Spain) and it is classified as Critically Endangered according to the International Union for Conservation of Nature (IUCN) categories, and as En Peligro de Extinción in the Catálogo Regional de Flora Silvestre Protegida de la Región de Murcia. Due to this fact and the little prior knowledge about the species, the aim of this thesis is to study biological ad ecological traits of A. chrysantha in order to establish appropriate measures for its conservation. Thus, this work includes the study of: (1) morphology, anatomy and germination behavior of the heteromorphic achenes of A. chrysantha; (2) the spatial and temporal dispersal traits of the achenes and the ...
