title: Seed contaminants: an overlooked pathway for the introduction of non-native plants in Sardinia (Italy)

description: The accidental introduction of alien plants through contaminated seed is a source of new incursions and subsequent invasions that can impact natural habitats, agriculture and forestry. While seed lots for agricultural crops are often well regulated through a certification process, the trade of many other types of seeds is largely unregulated. Here, we evaluate the risk of seed lots trade as a pathway for invasive alien plant species in Sardinia (Italy), by identifying and quantifying the presence of contaminant species. The study included uncertified commercial seeds as well as the ones sold as pet feed. We randomly sampled 39 seed packets, from multiple sources, including novel forage crops under experimental testing (Fc), flower mixtures (Fm), recreational lawn mixtures (Lm) and pet feed (Pf). Germination and viability were analysed on the seed commodity of Pf. A total of 231 contaminant species was found, belonging to 88 genera and 34 families. Moreover, among the contaminants, the non-native invasive agricultural weeds <i>Amaranthus</i> sp. pl. and <i>Echinochloa</i> sp. pl. were found. Our results showed that unregulated seed contaminants are associated with a high risk of non-native plants entry and their potential establishment in Sardinia.

title: Phylogenetic relationships and taxonomic issues in <i>Gastridium</i> (Poaceae) inferred from plastid and nuclear DNA sequence analysis

description: <i>Gastridium</i> P. Beauv. is a Mediterranean-Paleotropical member of the Poaceae family, whose species number and diversity are still imperfectly known. We examined patterns of DNA diversity at two plastid (<i>trn</i>H-<i>psb</i>A, <i>trn</i>L-F) and one nuclear (ITS) DNA markers in 44 individuals of the four taxa (<i>Gastridium lainzii</i>, <i>G. phleoides</i>, <i>G. scabrum</i>, <i>G. ventricosum</i>) recently recognised by different authors, based on morpho-ecological descriptors. Diversity data were explored with multiple statistical and phylogenetic tools, and integrated with available GenBank sequences of <i>Gastridium</i> and closely related genera. Despite the limited variability detected, evidence of within-taxon genetic cohesion and estimates of molecular divergence comparable with those of species in the same subtribal lineage (Agrostidinae) were recovered. The identified plastid genealogies are congruent with a subdivision of the genus into four distinct species, coherently with collected morphological descriptors. Phylogenetic reconstructions with ITS were less corresponding to the four taxa, possibly due to reticulation and polyploidization. The broader plastid and nuclear tree topologies were consistent with previous assessments, highlighting the overall little resolution of species and genera within Agrostidinae, and the close relationships shared by <i>Gastridium</i> and <i>Triplachne</i>. The hypothesis of closely related, but separately evolving, lineages within <i>Gastridium</i> is discussed, suggesting a re-evaluation of its current taxonomy.

title: A revision of the syntaxonomy of the Apennine-Balkan <i>Quercus cerris</i> and <i>Q. frainetto</i> forests and correct application of the name <i>Melittio-Quercion frainetto</i>.

description: <i>Melittio-Quercion frainetto</i> and <i>Melittio-Quercion confertae</i> are two alliances, which were proposed about simultaneously 40 years ago through two different papers regarding southern Italy and southern Greece, respectively. The aims of this paper are to establish valid name, nomenclatural type and distribution range of these two alliances and to verify whether they display a sufficient degree of syntaxonomic autonomy when compared to the ecologically and geographically neighbouring alliances. A data matrix composed of 43 frequency columns summing 1242 phytosociological relevés x 625 taxa was prepared and statistically analysed. The results suggested that the thermophilous <i>Quercus cerris</i> and <i>Q. frainetto</i> oak woods of the southern Apennines and the southern Balkans deserve to be classified in two separated alliances. The application of the principle IV of ICPN established that the correct name of the alliance is <i>Melittio albidae-Quercion frainetto</i> Barbéro, Bonin, Gamisans et Quézel in Bonin et Gamisans 1976 and that it was typified in southern Italy. Accordingly, the new name <i>Geranio asphodeloidis-Quercion frainetto</i> is here proposed for southern Greece in substitution of <i>Melittio-Quercion confertae</i> (<i>nom. illeg</i>.). The syntaxonomic proposal advanced in this paper brings significant modifications in the current version of the checklist of the European syntaxa (Eurovegchecklist).

title: Cdc42 controls secretory granules morphology in rodent salivary glands in vivo

description: We previously reported that the small GTPase Cdc42 negatively regulates endocytosis in the salivary gland of live mice. By using intravital subcellular microscopy, we showed that depletion of Cdc42 causes the mis-sorting of plasma membrane components into intracellular vesicles, ultimately leading to the impairment of the homeostasis of the apical plasma membrane. In this study, we report that, besides, Cdc42 depletion alters the ultrastructure of large secretory granules analyzed by transmission electron microscopy. We found that lack of Cdc42 increases the number of granules per cell and alters their structure. Specifically, granules are smaller, less circular and exhibit heterogeneous electron densities in their lumen. Our findings suggest a novel role for Cdc42 in controlling granule biogenesis and/or maturation.

title: New insights into the limited thermotolerance of anhydrobiotic tardigrades

description: The recent discovery of an upper limit in the tolerance of an extremotolerant tardigrade to high temperatures is astounding. Although these microinvertebrates are able to endure severe environmental conditions, including desiccation, freezing and high levels of radiation, high temperatures seem to be an Achilles’ heel for active tardigrades. Moreover, exposure-time appears to be a limiting factor for the heat stress tolerance of the otherwise highly resilient desiccated (anhydrobiotic) tardigrades. Indeed, the survival rate of desiccated tardigrades exposed to high temperatures for 24 hours is significantly lower than for exposures of only 1 hour. Here, we investigate the effect of 1 week of high temperature exposures on desiccated tardigrades with the aim of elucidating whether exposure-times longer than 24 hours decrease survival even further. From our analyses we estimate a significant decrease in the 50% mortality temperature from 63ºC to 56ºC for <i>Ramazzottius varieornatus</i> exposed to high temperatures in the desiccated tun state for 24 hours and 1 week, respectively. This negative correlation between exposure-time and tolerance to high temperatures probably results from the interference of intracellular temperature with the homeostasis of macromolecules. We hypothesize that high temperatures denature molecules that play a vital role in sustaining and protecting the anhydrobiotic state.
