Interactive Effects of Genotype and Molybdenum Supply on Yield and Overall Fruit Quality of Tomato
2019
Molybdenum (Mo) is an essential trace element for plant growth, development, and production. However, there is little known about the function and effects of molybdenum in tomato plants. The present study assessed the influences of different Mo concentrations on four tomato F1 hybrids (“Bybal” F1, “Tyty” F1, “Paride” F1, and “Ornela” F1) grown using a soilless system with different Mo levels [0.0, 0.5 (standard NS), 2.0, and 4.0 μmol L−1, respectively]. The crop yield, plant vigor, fruit skin color, TA, fruit water content as well as the accumulation of SSC, and some antioxidant compounds such as lycopene, polyphenols and ascorbic acid were evaluated. The minerals concentration, including n…
Paleoflora y Paleovegetación de la península Ibérica e islas Baleares: Plioceno-Cuaternario
2012
Libro que reune yacimientos ibéricos con resgistros de paleovegetación, tanto de macrorestos (carbón, semillas, maderas) como de microrrestos (poles, esporas). The book meets Iberian sites with records of palaeovegetation. There are sequencies of macroremains (coal, seeds, wood) and microrrestos (poles, spores).
Effects of plant type on two strawberry cultivars in Siciliy
2014
In Sicily fresh plants have for years been replacing the once popular cold-stored ones. Good early cropping is the aim of all strawberry growers in the island s Marsala district. The present trial tested the response of the new strawberry cultivars Sabrosa and Florida Fortuna using fresh plug and bare-root plants. Florida Fortuna plug-plants turned out to be the most promising type as a cash crop in delivering extra early ripening.
The intestinal ecosystem and probiotics
2016
The term "probiotic" comes from the greek "pro bios" and means "pro life": Nowadays, an increasing number of pharmaceutical preparations and functional foods are enriched with probiotics and for the patients it is increasingly important to receive information needed to know how to orient in the choice. The benefits from probiotics are many and include the modulation of the intestinal microflora (stimulation of beneficial bacteria and inhibition of pathogens), the support of bowel function and the stimulation of the immune system. This broad spectrum of beneficial effects to maintain efficient the intestinal ecosystem. Therefore, probiotics are an useful tool to prevent the formation of diso…
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
Using probability of extinction to evaluate the ecological significance of toxicant effects
2000
A large component of uncertainty in ecological risk assessment (ERA) arises from the disparity between the time scale of toxicity measurements and the time scale of predictions of ERA models. It is difficult to make predictions about the persistence of populations from data from short-term toxicity tests. Reproductive toxicity tests provide data about how population growth rate (r) is reduced with toxicant exposure. Although reduction in r is believed to be one of the most important effects of toxicant exposure, its ecological significance has been difficult to quantify. For rotifers, r is typically reduced by 10 to 15% at no-observed-effect concentrations (NOEC). We investigated r reductio…

Hieracium barrelieri, a new hawkweed species from S Italy, with notes on Tenore’s Hieracium murorum var. barrelieri (Asteraceae)
2015
A new species from Montevergine in Campania, Hieracium barrelieri, is described in detail. It is closest to H. acanthodontoides of H. sect. Acanthodontoidea. H. murorum var. barrelieri, an obsolete taxon described by Tenore, is also discussed, as it was partly based on the same population.
Targeting antibiotic resistant bacteria with phages reduces bacterial density in an insect host
2018
Phage therapy is attracting growing interest among clinicians as antibiotic resistance continues becoming harder to control. However, clinical trials and animal model studies on bacteriophage treatment are still scarce and results on the efficacy vary. Recent research suggests that using traditional antimicrobials in concert with phage could have desirable synergistic effects that hinder the evolution of resistance. Here, we present a novel insect gut model to study phage-antibiotic interaction in a system where antibiotic resistance initially exists in very low frequency and phage specifically targets the resistance bearing cells. We demonstrate that while phage therapy could not reduce th…
Mapping a-priori defined plant associations using remotely sensed vegetation characteristics
2014
Abstract Incorporation of a priori defined plant associations into remote sensing products is a major challenge that has only recently been confronted by the remote sensing community. We present an approach to map the spatial distribution of such associations by using plant indicator values (IVs) for salinity, moisture and nutrients as an intermediate between spectral reflectance and association occurrences. For a 12 km 2 study site in the Netherlands, the relations between observed IVs at local vegetation plots and visible and near-infrared (VNIR) and short-wave infrared (SWIR) airborne reflectance data were modelled using Gaussian Process Regression (GPR) (R 2 0.73, 0.64 and 0.76 for sali…
