“…It should not be forgotten that the Habitats Directive relies heavily on a syntaxonomical basis (RivasMartínez et al 1993). Accordingly, the recognition of an alliance peculiar to the SE (Mota et al 2010) would surely have a positive impact on the conservation policies aimed at the gypsum outcrops within these territories. Although the current Habitats Directive only recognizes one natural habitat for gypsum soils (i.e., 1520: Iberian gypsum vegetation) clearly identified with the order Gypsophiletalia, future revision of the Directive cannot be ruled out, perhaps using other syntaxonomical levels, such as alliances or associations.…”

Genetic diversity, genetic structure and phylogeography of the Iberian endemicGypsophila struthium(Caryophyllaceae) as revealed by AFLP and plastid DNA sequences: connecting habitat fragmentation and diversification

et al. 2013

Iberian gypsum outcrops are highly fragmented and ecologically challenging environments for plant colonization. As gypsophytes occur exclusively in such habitats, they are ideal models for the study of both the effects of habitat fragmentation and selection on population genetic diversity and structure. In this study, we used amplified fragment length polymorphism (AFLP) and plastid DNA sequences to investigate the phylogeographical history of the Iberian plant Gypsophila struthium (Caryophyllaceae), a widespread endemic restricted to Iberian gypsum outcrops. Gypsophila struthium consists of two subspecies that differ in the architecture of their inflorescence and have mostly allopatric ranges. Gypsophila struthium subsp. struthium occurs in central, eastern and south‐eastern Iberia, whereas G. struthium subsp. hispanica occurs in northern and eastern areas. AFLPs revealed low but significant genetic differentiation between the subspecies, probably as a result of a recent diversification during the Pliocene–Pleistocene. In the geographical contact zone between the taxa, the Bayesian analyses revealed populations with mixed ancestries and genetic clusters predominantly of one or the other subspecies, indicating incomplete reproductive barriers between them. Plastid DNA haplotypes revealed strong geographical structure and testified to processes of isolation by distance and continuous range expansion for some haplotype clades. The Bayesian analyses of the population structure of AFLP data and nested clade phylogeographical analysis (NCPA) of plastid haplotypes revealed that the putative ancestral range corresponded to central and eastern populations of G. struthium subsp. struthium, with those lineages contributing through more recent expansion to increased genetic diversity and structure of the south‐eastern and eastern ranges of this subspecies and to the diversification of G. struthium subsp. hispanica in northern and eastern gypsum outcrops. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 654–675.

“…To preserve this natural heritage with adequate environmental protection programmes and to reduce the deleterious effects of the threats already mentioned, it is essential not only to have precise information about the distribution of these habitats and their associated species, but also to know the ecological and biogeographical patterns conditioning their distribution and abundance (Cerrillo et al 2002;Merlo et al 1998Merlo et al , 2009Mota et al 1998Mota et al , 2003Mota et al , 2004aMota et al , 2009Mota et al , 2010Garrido-Becerra et al 2004;).

The distribution of Iberian gypsophilous flora as a criterion for conservation policy

et al. 2011

Within the EU territory, gypsum habitats with a peculiar flora are exclusively restricted to the eastern half of the Iberian Peninsula. The Habitats Directive considers the scrublands belonging to the Gypsophiletalia order as priority habitats (habitats 1,520). Although these scrublands do not represent the only kind of vegetation associated with gypsum outcrops, they tend to occur together with other types of communities that grow exclusively on this substrate. As far as vascular flora is concerned, there are some species that grow exclusively on Iberian gypsums and are accordingly included in the Spanish Red List. Besides, given the fragmentary character and punctuated location of these outcrops, the protection of this Iberian habitat and its flora is, therefore, an enormous challenge for any preservation policy. The disjunct distribution of the flora faithfully reflects this geological feature of gypsum areas. Consequently, a proper and detailed knowledge of the distribution of the gypsophilous vascular flora can be very useful in formulating an efficient preservation policy for these habitats. Using the checklist of the Iberian gypsophilous flora, we collected a wide data base with records of distribution arranged into 10 9 10 km UTM grids. For each of the 1,241 grids where at least one gypsophyte was recorded we reckoned a series of parameters in order to determine the priority level of the flora for preservation purposes. These parameters were specific richness, gypsophily level, continuous and discontinuous rarity and endangered level. Our analyses reveal serious gaps in the Spanish network of protected sites with gypsophilous flora, the most important being located in the Hoya de Baza.
