Plant autoecology and population genetics provide a perspective on the likelihood of natural regeneration, which is critical when designing conservation strategies for endangered species. The threatened coastal plant Malcolmia littorea (Brassicaceae) was sampled across its European distribution and studied for genetic diversity and seed fitness, wi...

Good‐quality dry seeds of some orchids have the potential to survive for decades under conventional seed‐bank conditions, but further research is needed to fill existing gaps in knowledge regarding seed behaviour under long‐term dry storage. The objectives of this study were to evaluate germination ability on two asymbiotic culture media with diffe...

The need to optimize seed banking efforts has stimulated research for rapid methods to estimate quality in seed-lots. For terrestrial orchids, viability testing using tetrazolium (TTC) staining requires chemical scarification, as seeds have an impermeable testa. Different seed-coat permeability may affect TTC staining, thus affecting the results. T...

This integrated study provides new insights into pollen and seed morphology and pollen hetero-morphism of four closely related annual taxa of Viola sect. Melanium. The plant material, both fresh and dried, was collected in Italy and studied using light and scanning electron microscope. Palynological data for V. hymettia together with a detailed com...

Isoëtes sabatina is an aquatic quillwort endemic to Italy. It is one of the rarest quillworts in Europe, and is critically endangered due to restricted range and to the continuous decline of both population and habitat quality. This study aims to develop an optimized protocol to reproduce and grow I. sabatina sporelings. Mature and immature megaspo...

Forest Orchidaceae are important for European temperate forests, yet their distribution and abundance have so far interested limited research. In three pure or mixed silver fir stands in the Foreste Casentinesi National Park (NP) (Northern Apennines, Italy) we analysed how structural traits in mature and old-growth forests affected orchid communiti...

This is the sixth issue of the series of germination reports from Mediterranean areas (sensu Med- Checklist). It comprises germination protocols for 29 taxa, 19 of which are endemic, preserved in six seedbanks from the Ribes and/or GENMEDA networks. The investigated taxa and populations are Leucanthemum tridactylites, Achillea barrelieri subsp. bar...

Assessing the performance of spontaneous plants in abandoned quarries under future environmental scenarios is important for successful restoration practices. Air warming is one of the most relevant ongoing climatic changes in the Mediterranean. We tested the effects of increasing temperature on the germination of five species spontaneously colonisi...

1. Isoëtes are iconic but understudied wetland plants, despite having suffered severe losses globally mainly because of alterations in their habitats. We therefore provide the first global ecological assessment of aquatic Isoëtes to identify their environmental requirements and to evaluate if taxonomically related species differ in their ecology. 2...

Highlights •Microbial communities associated with different native species were analyzed. •Microbial communities responses to invasion varied for different native species. •The responses varied in the study sites and were linked to edaphic conditions. •Fungal components of the communities are more affected than bacteria ones. •Carpobrotus invas...

We studied the vascular flora of the isthmus of Feniglia, a Nature Reserve in southern Tuscany stretching between the Italian Peninsula and Mt. Argentario. Since the nineteenth century, the area has undergone significant environmental modifications due to intensive grazing and deforestation. Later, rehabilitation interventions were carried out, inc...

Orchidaceae is one of the largest and most diverse families of flowering plants in the world but also one of the most threatened. Climate change is a global driver of plant distribution and may be the cause of their disappearance in some regions. Forest orchids are associated with specific biotic and abiotic environmental factors, that influence th...

Carpobrotus species were introduced in Europe to stabilise dunes and for ornamental purposes, resulting in highly invasive thanks to their fast growth and spread, and the production of a high number of seeds. In addition, their litter exerts a strong allelopathic effect, reducing germination and establishment rates of native species. Within the pro...

The Italian seed bank network (RIBES) aims to improve the quality and safety of the germplasm reserves of native plant species in Italy to ensure the long-term conservation of endangered and/or endemic flora. The strategy includes traditional methods to secure seed conservation. A comprehensive priority list for seed collection is being defined, it...

Herbaria may represent remarkable sources of viable diaspores for recovering lost genetic variation and extinct plant species, but the application of rewilding extinct species using these collections has not been explored in detail. De-extinction in plants may be achieved by germinating viable diaspores or culturing tissues preserved in herbarium s...

The split between conservation science and real-world application is an ongoing issue despite several calls for unification. Researchers are empowered to partially bridge the research-implementation gap by making their findings more accessible. Cypripedium calceolus is the most recognizable orchid of the European flora, and is currently facing habi...

• Isoëtes sabatina is the rarest aquatic quillwort in Europe. Although recently found (2013) in Lake Bracciano (central Italy), the species is just one step away from extinction with an estimated population not exceeding 400 individuals and a spatial range of a few hundred square metres. • Lake Bracciano is a deep, oligo-mesotrophic Mediterranean v...

The Italian vascular flora is one of the richest in the European Union and the Italian peninsula is located at the centre of the Mediterranean Basin, one of the 25 world biodiversity hotspots with an exceptional loss of habitats and species (1). Preliminary to any conservation initiative concerning plant diversity, a prioritization of the most enda...

Limodorum species are hard-to-cultivate, germinating with difficulty or not germinating at all on a number of media. The present work was focused on the effects of seed sterilization-scarification methods and of different nitrogen sources on in vitro seed germination and seedling development of Limodorum abortivum, L. brulloi and L. trabutianum. Ou...

In 2011, MATTM and SBI started a collaboration for the New Red List of Italian Vascular Flora (1, 2), according to the IUCN Categories and Criteria. IUCN Red Lists represent the most widely applied protocol for evaluating species extinction risk, because they facilitate objective and replicable assessments (3). National assessments provide a basis...

The conservation of species listed in the Bern Convention and European Directive 1992/43/EEC (so-called policy species) is mandatory for European Union (EU) countries. We assessed the conservation status of Italian policy species, based on the IUCN categories and criteria, to evaluate the effectiveness of existing protection measures at the nationa...

Based on the analysis of relevant literature and of specimens from European herbaria, Viola nana and V. henriquesii, currently included in V. kitaibeliana, are reaffirmed as independent species. A lectotype is designated here for V. nana from the original material found in the Herbier De Candolle in Genèva Herbarium (G). A lectotype and three synty...

Malcolmia littorea is a plant which occurs on the coastal habitats of Portugal, Spain, France, Italy, Algeria and Morocco with a disjointed distribution. The continuous fragmentation and degradation of its natural habitat are threatening the persistence of this species, reducing the abundance of its populations together with their genetic variabili...

Limodorum trabutianum is a steno-Mediterranean orchid with a highly fragmented distribution area that includes Morocco, Algeria, Portugal, Spain, France, and Italy where it is threatened with extinction.

Pollen heteromorphism is frequent in the section Melanium of the genus Viola, in which over 80% of the species produces pollen morphs with 3 to 6 apertures. Some authors have highlighted that many factors can affect the proportion of the different pollen types in perennial species, and that this proportion can change among populations. This work fo...

Terrestrial orchids are experiencing a great extinction risk because of a multiplicity of threatening processes.
