Characterization and conservation of Clinopodium raimondoi Spadaro, A.S. Faqi & Mazzola germplasm in the Parco della Favorita of Palermo city (Si…
2017
In urban areas, the parks represent an important source of plant biodiversity. The Parco della Favorita is the largest green area in Palermo city (Sicily, Italy). Clinopodium raimondoi Spadaro, A.S. Faqi & Mazzola is an aromatic plant species which has a range of uses in Sicilian traditional culture. The essential oil of this species is rich in terpene components and its aroma is similar to that of mint. The aim of this study was to enhance the germplasm of C. raimondoi in the Parco della Favorita. A collection-field was set up within the park. The main biometric and productive parameters of the species were determined and gas chromatographic analyses were carried out to determine the quali…

Managing the Historical Agricultural Landscape in the Sicilian Anthropocene Context. The Landscape of the Valley of the Temples as a Time Capsule
2021
The debate over whether we are entering the Anthropocene Epoch focuses on the unequal consumption of the Earth system’s resources at the expense of nature’s regenerative abilities. To find a new point of balance with nature, it is useful to look back in time to understand how the so-called “Great Acceleration”—the surge in the consumption of the planet’s resources—hastened the arrival of the Anthropocene. Some particular places—for various reasons—survived the Great Acceleration and, as time capsules, have preserved more or less intact some landscape features that have disappeared elsewhere. How can we enhance these living archives that have come down to us? Through the analysis of the case…
Floral scent in Iris planifolia (Iridaceae) suggests food reward
2018
Iris species can adopt different pollination strategies to attract their pollinators, generalized shelter-mimicking, specialized deceptive sexual-mimicking or food-rewarding. As attractive stimuli, Iris flowers may use their colours, large-size, symmetry, and volatile organic compounds (VOCs). However, relatively few studies in- vestigated Iris floral olfactory cues in the context of plant-visitor/pollinator interactions. In the present study we combined the identification of the floral volatiles of the nectariferous I. planifolia with insects visiting its flowers to gather data on its biology. Floral volatiles were collected in the natural environment by dynamic headspace and analysed by g…
Root fungal endophytes: identity, phylogeny and roles in plant tolerance to metal stress.
2021
International audience; Metal trace elements accumulate in soils mainly because of anthropic activities, leading living organisms to develop strategies to handle metal toxicity. Plants often associate with root endophytic fungi, including nonmycorrhizal fungi, and some of these organisms are associated with metal tolerance. The lack of synthetic analyses of plant-endophyte-metal tripartite systems and the scant consideration for taxonomy led to this review aiming (1) to inventory non-mycorrhizal root fungal endophytes described with respect to their taxonomic diversity and (2) to determine the mutualistic roles of these plant-fungus associations under metal stress. More than 1500 species in…
Modelling the European Farmland Bird Indicator in response to forecast land-use change in Europe
2011
International audience; The European Farmland Bird Indicator (EFBI) has been adopted as a Structural and Sustainable Development Indicator by the European Union. It is an aggregated index integrating the population trends of 33 common bird species associated with farmland habitats across 21 countries. We describe a modelling method for predicting this indicator from land-use characteristics. Using yearly historical land-use data of crop areas derived from the FAO databases (1990–2007) and published population data of farmland birds at the national level for the same period, we developed a series of multiple regression models to predict the trend of the EU state specific indicator, and the E…
Biological richness of a large urban cemetery in Berlin. Results of a multi-taxon approach.
2016
Abstract Background Urban green spaces can harbor a considerable species richness of plants and animals. A few studies on single species groups indicate important habitat functions of cemeteries, but this land use type is clearly understudied compared to parks. Such data are important as they (i) illustrate habitat functions of a specific, but ubiquitous urban land-use type and (ii) may serve as a basis for management approaches. New information We sampled different groups of plants and animals in the Weißensee Jewish Cemetery in Berlin (WJC) which is one of the largest Jewish cemeteries in Europe. With a total of 608 species of plants and animals, this first multi-taxon survey revealed a c…
Effect of mass rearing on the genetic diversity of the predatory mite Amblyseius swirskii
2019
Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is a predatory mite used to control whiteflies and thrips in protected crops. This biocontrol agent, originating from the Eastern Mediterranean region, has been mass-reared for commercial use since 2005 and is widely used in augmentative biocontrol programs. As a polyphagous predator, it has to cope with different biotic and abiotic factors. However, possible adaptation to mass rearing for production might be hindering its resilience and capacity for optimum performance in the field. In this study, we investigated the effect of long-term mass rearing on the genetic diversity of A. swirskii. We identified six microsatellite loci from w…
Studying illegal online trades in plants: market characteristics, organisational and behavioural aspects, and policing challenges
2020
AbstractIllegal commerce in plants and their derivatives threatens and destroys numerous species and important natural resources, and may cause phytosanitary and health problems. This illegal trade, which has been boosted by the commercialisation of the Internet, has been relatively overlooked in criminological research. Furthermore, the policing of illegal plant markets remains limited and poorly resourced, with law enforcement agencies lacking awareness and technical capacity in investigation and prosecution services. Based on semi-structured interviews with law enforcement officers and other relevant experts, this study, developed in the context of the ESRC-funded project “FloraGuard: Ta…
Response of grapevine (Cabernet Sauvignon cv) to above ground and subsurface drip irrigation under arid conditions
2018
Abstract The response of wine grapes to irrigation systems was investigated in a Cabernet Sauvignon/140 Ru vineyard in sandy loam soil in Sicily during a two-year study. Two different drip irrigation systems were evaluated: one surface drip and two subsurface drip irrigation systems, with the trickle line located at different distances from vine trunks. Vegetative and quantitative parameters, must quality and root distribution were compared among irrigation treatments. During the two study years, irrigation of grapevines via a subsurface drip system resulted in greater water use efficiency without affecting must composition. Establishing the trickle line near the trunk positively influenced…
