Concentration of Potentially Toxic Elements in Various Berries Grown in Allotment Gardens of Rīga City, Latvia
2017
Abstract Concentration of trace and major elements is an important indicator of nutritional value of food, also regarding cultivated food crops like fruits, berries, and vegetables. Concentration of elements differs regionally and is influenced by various factors. Nevertheless, some chemical elements (As, Cd, Hg, Ni, Pb, Zn, etc.) are known as environmental pollutants and may affect the quality and safety of crops and food products. The aim of the study was to determine the concentration of potentially toxic elements like Cd, Cr, Cu, Fe, Ni, Pb, and Zn in samples of berries grown in allotment gardens of Rīga city. Dried and homogenised samples of raspberries, strawberries, red currants, bla…
Phytophthora Diversity in a Sentinel Arboretum and in a Nature Reserve Area
2020
Most soilborne Phytophthora species are invasive plant pathogens and nursery plants for transplanting are considered a primary pathway for the introduction of exotic Phytophthora species into plant diversity conservation areas and sites. As a preliminary step toward investigating this subject, we compared the diversity of Phytophthora in the protected natural area Complesso Speleologico Villasmundo S. Alfio Nature Reserve (NR) (Melilli, Siracusa) and the botanical garden (BG) of the University of Catania (Catania), in eastern Sicily (southern Italy). Sampling was carried out during the spring of 2019. Overall 29 rhizosphere soil samples were collected, 17 from different types of vegetation …
Contributi alla interpretazione, conservazione e restauro dei manufatti storico-artistici dell’Orto Botanico di Palermo: il Paride di Nunzio Morello
2017
Contributions to the interpretation, conservation and restoration of the historical and artistic artifacts of the Botanical Garden of Palermo: the Paride by Nunzio Morello – Purely cognitive and conservative requirements of the historical-artistic heritage of the Botanical Garden of the University of Palermo, have led the authors to present one of the most representative monuments of such Garden that is of great artistic and cultural value in the City of Palermo: the Paride Pensante, a marble sculpture made in 1839 by the Palermo sculptor Nunzio Morello - a pupil of the most famous artist Valerio Villareale - donated to his homeland and placed in the men- tioned Botanical Garden, in the squ…
Storie di giardini e storie di città
2021
Quanti modi ci sono per raccontare una storia, la storia di una città densa e plurima quale è New York City? Molte certamente dato che molti sono i quadri su cui ragionare. Una chiave di lettura interessante, e certamente differente da quelle che generalmente ritroviamo, è quella del ruolo che hanno avuto gli spazi verdi urbani, i giardini, a partire dai parchi storici, nella crescita della città di New York sia nei cinque distretti sia come sistema connettivo fisico e sociale. Il giardino, quindi, può essere visto come punto di collegamento fra l’uomo e il mondo in cui vive, dato che in tutte le epoche l’uomo ha sentito il bisogno di riconciliarsi con l’ambiente circostante, e si è così cr…
Molecular characterization of cucumber mosaic virus isolates infecting ornamental species cultivated in the botanical garden of Bologna university.
2006
During an epidemiological survey carried out in the Botanical Garden at Bologna University, Cucumber mosaic virus (CMV) has been detected by applying PAS-ELISA technique infecting some ornamental species exhibiting a severe symptomatology on the leaves. Datura innoxia Miller. showed mosaic and leaf-curling; Globularia nudicaulis L. produced narrowed leaves with a yellow mosaic and/or variegation; Eupatorium cannabinum L. showed a systemic chlorotic and/or yellow mosaic and stunting. Reverse transcription-polymerase chain reaction (RT-PCR) and single strand conformation polymorphism (SSCP) were employed to characterise these CMV isolates. Total RNA was extracted from symptomatic leaf samples…
Gardens on Canvas and Paper: Cataloguing Botanical Abundance in Late Medici Tuscany
2016
What is the purpose of portraying a branch from a pear tree in bloom and fruit, of listing hundreds of citrus varieties or of dissecting a huge truffle? When Cosimo III (1642–1723), the penultimate grand duke of the Medici dynasty, commissioned artists and botanists alike to create comprehensive visual and textual catalogues of Tuscan flora, aesthetics and curiosity seemed to go hand in hand with a demonstration of knowledge and prosperity. This article deals with the collection of botanical paintings by Bartolomeo Bimbi (1648–1730), housed in the Casino della Topaia close to the city of Florence, and with the mainly handwritten work of the grand ducal botanist Pier Antonio Micheli (1679–17…
Virtues for the Anthropocene
2015
The paper discusses some difficulties that life in Anthropocene poses to our ethical thinking. It describes the sort of ethical task that individuals find themselves confronting when dealing with the planetary environmental quandaries that characterise the new epoch. It then asks what, given the situation, would count as environmentally virtuous ways of looking at and going about our lives, and how relevant virtues can be developed. It is argued that the practice of gardening is distinctively conducive to that objective. Finally, some garden virtues that will be of special importance in the Anthropocene, but have so far been largely neglected by environmental ethicists, are listed and descr…
El diseño del «verde» en el planeamiento del siglo XIX y en Palermo
2013
[SPA] La relación existente entre hombre y jardín ha evolucionado en el tiempo y en relación al lugar. En Europa, en Italia y sobre todo en Palermo es interesante analizar cómo este vínculo se ha desarrollado, y cómo ha influido la función del jardín dentro de la ciudad, a lo largo de los siglos. En la cultura europea, la noción de tiene una raíz etimológica común derivada del latín de la Edad Media Gardinium. Éste se refería a un lugar cerrado y amurallado, evolución del hortus conclusus romano hasta el gardinus medieval, y testimoniaba la permanencia tipológica de una arquitectura con pórtico perimetral, presente también en el claustro de los monasterios. [ENG] The relationship between ma…
Impact of 70 years urban growth associated with heavy metal pollution
2014
Historical trends in trace element deposition were analyzed using herbaria specimens. We determined Al, Fe, Mg, Mn, Ca, Na, P, K, S, As, Cd, Cr, Cu, Ni, Pb and Zn contents in leaves of eight specimens collected in 1941. To assess changes, we collected the same plants from a botanical garden in 2012. The concentrations of major elements showed large species variability. However, temporal trends were predominately detected for heavy metals. The Cd, Ni and Cr contents in the 2012 leaves were 10, 13 and 16 times higher, respectively, than in 1941. Urban activities have substantially raised the levels of these metals in urban atmospheres due to changes in human activities over 70 years of urban …
A transdisciplinary educational experience at the Botanical Garden around scientific travelers
2019
In the framework of the transdisciplinary educational innovative project “Sciences and Arts” at the University of Valencia, we present here the design and outcome of an activity around the phenomenon of scientific travelers. It consisted in a scientific-literary tour through the Botanical Garden of the University of Valencia, that 100 students from the subjects “Natural Sciences for teachers” and “Literary training for teachers” attended. The activity was designed as a collaborative work in which scientific travelers served as a pretext to address six educational aspects that the students from each subject tackled in two different ways: from a more scientific than literary approach and vice…
