Ephemeral wetland vegetation (EWV) in the Mediterranean Basin appears in temporary wetlands where favourable hydrological conditions exist only for a short time and year-to-year variability is high. Here, we report results of the seed germination, dormancy and desiccation tolerance of eight annual species living in this vulnerable habitat. Experiments were(More)
Seed dormancy and germination characteristics may vary within species in response to several factors. Knowledge of such variation is crucial to understand plant evolution and adaptation to environmental changes. We examined the correlation of climate and population genetic differentiation (ISSR) with primary seed dormancy and germination behaviour in(More)
The taxonomically complicated Crocus series Verni is characterized by high intra- and interspecific variability of karyotypes (2n = 8–23). With the aim to get more insights into complex karyotype evolution and to clarify the taxonomy of this group, we combined morphological (twelve characters), molecular (chloroplast DNA: trnL–trnF, ndhF; nuclear DNA: ITS,(More)
The aim of this work was to examine whether seed ecophysiological traits in three closely related Crocus species were associated with ecological niche differentiation and species divergence. Seeds of the temperate tetraploid cytotype of Crocus neapolitanus, the sub-Mediterranean C. etruscus and the Mediterranean C. ilvensis were placed either on agar in the(More)
Rhamnus glaucophylla Sommier is an endemic small tree or shrub belonging to sect. Eurhamnus. It grows on cliffs of the Apuan Alps and of the Lucca Apennine in Tuscany (Italy). ISSRs were used to detect the genetic diversity within and among five populations representative of the species distribution range. Moderate levels of genetic diversity were revealed(More)
Seed germination is the most important transitional event between early stages in the life cycle of spermatophytes and understanding it is crucial to understand plant adaptation and evolution. However, so far seed germination of phylogenetically closely related species has been poorly investigated. To test the hypothises that phylogenetically related plant(More)
Flowering plants employ a wide variety of signals, including scent, to attract pollinators. The aim of this work was to examine whether flower volatiles in four closely related Crocus species are linked to species divergence and to the current knowledge on their pollination syndromes. Fragrances of freshly opened flowers in Crocus etruscus, C. ilvensis, C.(More)
The factors driving genome size evolution in Liliaceae were examined. In particular, we investigated whether species with larger genomes are confined to less stressful environments with a longer vegetative season. We tested our hypotheses by correlating the genome size with other plant traits and environmental variables. To determine the adaptive nature of(More)
Mediterranean temporary ponds (MTPs) are very specialised and threatened habitats found in Mediterranean-like bioclimates worldwide. MTPs have received considerable attention over the past years because of the multiple ecological roles they play in the landscape. Nevertheless, seed germination, dormancy, and desiccation tolerance of species living in MTPs(More)
The taxonomy of the closely related Silene capraria, S. neglecta and S. nocturna in Italy is investigated, by means of morphometric and karyological analyses. The chromosome numbers of S. capraria and S. neglecta (both diploid with 2n = 24) are here reported for the first time. On the basis of the morphological results, we propose the species rank for S.(More)
