New ichnites from the Middle Triassic of the Iberian Ranges (Spain): paleoenvironmental and paleogeographical implications

2010

17 pages; International audience; The Iberian Basin or its present-day expression, the Iberian Ranges, was refilled with red bed sediments of alluvial origin during the late Olenekian–Anisian period represented by the Cañizar (Olenekian–Anisian) and Eslida (Anisian) Formations, both commonly known as Buntsandstein facies. In the late part of the Anisian, the Tethys Sea reached the eastern side of the Iberian microplate, represented by the shallow marine facies of the Landete and Cañete Formations, also called Muschelkalk facies. The ichnites studied in this paper belong to the Anisian continental-marine transition in the SE Iberian Ranges. The Cañizar Formation shows the oldest Triassic foo…

Ocean Circulation Model Applications for the Estuary-Coastal-Open Sea Continuum

2021

Coastal zones are among the most variable environments. As such, they require adaptive water management to ensure the balance of economic and social interests with environmental concerns. High quality marine data of hydrographic conditions e.g., sea level, temperature, salinity, and currents are needed to provide a sound foundation for the decision making process. Operational models with sufficiently high forecasting quality and resolution can be used for a further extension of the marine service toward the coastal-estuary areas. The Limfjord is a large and shallow water body in Northern Jutland, connecting the North Sea in the West and the Kattegat in the East. It is currently not covered …

Quality Factors Influencing Consumer Demand for Small Fruit by Focus Group and Sensory Test

2017

ABSTRACTThe market of berries is a niche of high value in Italy. Small fruit’s healthy properties are well known in the international market, but little is known about the reason for a low commercialization rate of fresh small fruit in Italy. The objective of this study was to assess consumer preferences in Italy for selected berry species. Moreover, the study aims to identify the relevant attributes of berries that affect the demand for this produce according to consumers and to compare these attributes. We assessed relevant attributes affecting the demand for fresh berries for different consumers’ profiles and compared berries’ attributes rankings. The results reveal high concordance betw…

Influence of an evoked pleasant consumption context on consumers’ hedonic evaluation for minimally processed cactus pear (Opuntia ficus-indica) fruit

2016

Awareness of the need to consider a consumption context when measuring the consumer's hedonic evaluation of a food product led researchers to investigate differences among responses given by consumers in different contexts. Previous studies measured the effects of evoking a consumption context, by using photographs or a written scenario, on hedonic evaluations of consumers for food products. This study investigated the influence of evoking a consumption context on hedonic evaluation of minimally processed cactus pear (Opuntia ficus-indica) fruit, using pictures and memories of pleasant personal experiences. A hedonic scale method for measuring food preferences was used. Hedonic evaluation o…

Rooting and acclimatization of micropropagatedHypericum perforatumL. native to Sicily

2017

Hypericum perforatum L. is traditionally used as a medicinal plant because of its different bioactive compounds with documented antidepressant and antiinflammatory activities. Plantlets’ mass production with high content of these secondary metabolites has been enhanced through in vitro culture but the process has often been stopped at the multiplication phase. A study was conducted in order to set up an efficient in vitro rooting and acclimatization protocol of a H. perforatum Sicilian genotype well-adapted to south Mediterranean conditions. Aseptic nodal segments were cultured onto a Murashige and Skoog (MS) basal medium supplemented with 4.44 µM 6-benzyladenine for multiplication. Microsh…

Characterization and purification of a bacterial chlorogenic acid esterase detected during the extraction of chlorogenic acid from arbuscular mycorrh…

2016

International audience; A Gram-negative bacterium able to grow using chlorogenic acid (5-caffeoylquinic acid) as sole carbon source has been isolated from the roots of tomato plants inoculated with the arbuscular mycorrhizal fungus Rhizophagus irregularis. An intracellular esterase exhibiting very high affinity (K-m = 2 mu M) for chlorogenic acid has been extracted and purified by FPLC from the chlorogenate-grown cultures of this bacterium. The molecular mass of the purified esterase determined by SDS-PAGE was 61 kDa and its isoelectric point determined by chromatofocusing was 7.75. The esterase hydrolysed chlorogenic acid analogues (caffeoylshikimate, and the 4- and 3-caffeoylquinic acid i…

Forty questions of importance to the policy and practice of native oyster reef restoration in Europe

2020

© 2020 The Authors. Aquatic Conservation: Marine and Freshwater Ecosystems published by John Wiley & Sons Ltd Oyster reefs are among the most threatened marine habitats globally. In Europe, oyster reefs have been extirpated from most locations within their historical range. Active restoration of the native oyster (Ostrea edulis) in Europe has grown substantially in recent years. In sharing experiences between oyster restoration projects in Europe at the Native Oyster Restoration Alliance conference, NORA2, in Edinburgh in May 2019, it became apparent that a number of similar barriers are experienced. This study identified the top 40 questions, which, if answered, would have the greatest inf…

Does the genetic diversity among pubescent white oaks in southern Italy, Sicily and Sardinia islands support the current taxonomic classification?

2020

AbstractMolecular diversity analysis of deciduous pubescent oaks was conducted for populations from Calabria, Sicily and Sardinia. The aims of this study were twofold. First, to provide data on the genetic diversity of pubescent oaks from an understudied area which currently exhibits one of the highest concentrations of pubescent oak species in Europe. Second, to verify if these groups of oaks are genetically distinct and if their identification is in accordance with the current taxonomic classification. Molecular analyses of leaf material of 480 trees from seventeen populations belonging to putatively different pubescent oak species (Quercus amplifolia,Q. congesta,Q. dalechampii,Q. ichnusa…

A financial feasibility study of an aquaponic system in a Mediterranean urban context

2019

Abstract Aquaponics is largely recognized as a solution for sustainable food production as it follows a biomimetic natural system and the circular economy principles, allowing large food productivity on nonagricultural land, and at the same time strongly reducing inputs and waste. In this study, we collected technical, economic and production data from a pilot aquaponic plant producing lettuce (Lactuca sativa) and Nile tilapia (Oreochromis niloticus) realized in an urban context in Sicily (Southern Italy), very suitable area for aquaponic production in relation to the Mediterranean climate. Through the determination of Net return and Break Even Point, analysing on one side the items which c…
