“…This could be also attributed to the higher extinction debt perennial species are generally displaying [98], as these species respond at a much slower pace to extrinsic disturbances [99][100][101] and thus to reduced population size and gene flow [97]. Consequently, the moderately high genetic diversity reported herein for all four studied taxa might actually be a delayed response to historical events and anthropogenic pressures and could indicate that the studied species' genetic diversity is at a pre-fragmentation state, a phenomenon observed in other parts of the world as well [102][103][104][105]. The moderately high genetic diversity of the study species seems to align as well with the trend recently observed in insular endemics from several (continental or oceanic) archipelagos displaying relatively high genetic diversity ( [106] and references therein).…”

Conservation Genetics of Four Critically Endangered Greek Endemic Plants: A Preliminary Assessment

The Mediterranean basin constitutes one of the largest global biodiversity hotspots, hosting more than 11,000 endemic plants, and it is recognised as an area with a high proportion of threatened taxa. Nevertheless, only a tiny fraction of the threatened Mediterranean endemics have their genetic diversity assessed, and we are unaware if and how climate change might impact their conservation status. This is even more pronounced in Eastern Mediterranean countries with a rich endemic flora, such as Greece, which hosts a large portion of the plant taxa assessed at the European level under the IUCN criteria. Using inter simple sequence repeats (ISSR) markers and species distribution models, we analysed the genetic diversity and investigated the impacts of climate change on four critically endangered and extremely narrow and rare Greek island endemic plants, namely Aethionema retsina, Allium iatrouinum, Convolvulus argyrothamnos, and Saponaria jagelii. All four species are facing intense anthropogenic threats and display moderate genetic diversity (uHe: 0.254–0.322), while climate change is expected to have a profound impact on their range size during the coming decades. A combination of in- and ex-situ measures, such as population reinforcement and seed bank conservation, are urgently needed in order to preserve these highly threatened and rare Greek endemics.

“…Certainly, the isolated nature of rocky outcrops is playing a major role in population differentiation in the Petrocoptis taxa studied here; populations would rarely exchange genes because are geographically isolated and the species have very low dispersal abilities (seeds are dispersed by gravity or by ants [54], with spider webs behaving as seed receptacles [55]), as stated by many authors in rocky habitats in other European countries [56][57][58]. Many rocky species show very high genetic divergence among populations (with values of F ST for nuclear markers typically around or over 0.5, as found in the present study), including Aquilegia spp.…”

Reusing Old and Producing New Data Is Useful for Species Delimitation in the Taxonomically Controversial Iberian Endemic Pair Petrocoptis montsicciana/P. pardoi (Caryophyllaceae)

Petrocoptis montsicciana and P. pardoi are two Iberian endemic taxa of Caryophyllaceae family with an unclear taxonomic delimitation, being variously treated as independent species, subspecies or even synonyms. In the present study, allozyme raw data obtained in the early 2000s have been reused with improved tools to survey genetic structure, and complemented with modeling and niche comparative analyses to shed light on species delimitation. Genetic structure was investigated using four approaches: Bayesian clustering, Monmonier’s algorithm, Principal Coordinate Analysis (PCoA), and Analysis of Molecular Variance (AMOVA). Ecological niche differences have been assessed through Ecological Niche Modeling (ENM) using MaxEnt, and Principal Component Analysis using both occurrence records and background climate (PCA-env). Genetic analysis confirms the distinction between both taxa, and the scenario of a progenitor–derivative (P–D) is suggested. In agreement with genetic data, niche analysis shows clear differences between their climate regarding species occurrences and background spaces. Climate divergence could be explained, at least partially, by the abundance of rocks where species live although differences at the microclimate instead of the regional climate should be explored in future research. Given the genetic distinction between P. montsicciana and P. pardoi, both taxa should be regarded as separate ‘Management Units’ (MUs).
