Salt Tolerance of Sea Flax ( L.), a Rare Species with Conservation Interest in Eastern Spain.

Seldom found in saltmarshes, is a halophyte of great conservation interest in the eastern Iberian Peninsula. Although the species has been reported in different plant communities, there is no information on its range of salinity tolerance or mechanisms of response to environmental stress factors. In this study, plants were subjected to increasing salt concentrations in controlled conditions in a greenhouse.

Postfire biodiversity database for eastern Iberia.

In the summer of 2012, two fires affected Mediterranean ecosystems in the eastern Iberian Peninsula. The size of these fires was at the extreme of the historical variability (megafires). Animals are traditionally assumed to recolonize from source populations outside of the burned area (exogenous regeneration) while plants recover from endogenous regeneration (resprouting and seeding).

Constitutive and Adaptive Traits of Environmental Stress Tolerance in the Threatened Halophyte Erben (Plumbaginaceae).

is a halophyte endemic to the E and SE Iberian Peninsula with interest in conservation. Salt glands represent an important adaptive trait in recretohalophytes like this and other species, as they allow the excretion of excess salts, reducing the concentration of toxic ions in foliar tissues. This study included the analysis of the salt gland structure, composed of 12 cells, 4 secretory and 8 accessory.

Responses to Increased Salinity and Severe Drought in the Eastern Iberian Endemic Species (Ranunculaceae), Threatened by Climate Change.

is an endangered, endemic species in East Spain, growing in areas of relatively low salinity in littoral salt marshes. A regression of its populations and the number of individuals has been registered in the last decade. This study aimed at establishing the causes of this reduction using a multidisciplinary approach, including climatic, ecological, physiological and biochemical analyses.

Intra- and Inter-Specific Crosses among L. (Asteraceae) Polyploid Relatives-Influences on Distribution and Polyploid Establishment.

How polyploids become established is a long-debated question, especially for autopolyploids that seem to have no evolutionary advantage over their progenitors. The polyploid complex includes diploid and two related tetraploids and . Our purpose was to study the mating system among these three taxa and to analyze its influence on polyploid establishment.
