PROTECTING BIODIVERSITY ON PRIVATE PROPERTY: AN EXPERIENCE IN CORLEONE (SICILY)
2017
Bona Furtuna is an organic farm located 8 km far from Corleone closed to Campofiorito (Palermo). The study area includes the slopes of Castro, Giardinello and Valle Fredda which goes up to Barraù Mt. included in the Special Areas of Conservation (ITA020037) according to the Natura 2000 European Birds and Habitat Directives. The high level of biodiversity is supported by over 502 taxa of vascular flora, 38 of which are endemic to Sicily. The study area is quite diversified from a bioclimatic point of view as well, presenting different gradients from the Lower Mesomediterranean (Upper dry) and the Lower Supramediterranean (Lower subhumid). The landscape has been shaped by frequent changes in …
Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnāls Nr. 1, 1957–1958
2023
Raksts tapis par PSRS izgudrotu Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnālu, kur uzskaitītas iesaistītās personas - pasniedzēji, zinātniskie asistenti un studenti no Pētera Stučkas Latvijas Valsts universitātes (LVU) Fizikas un matemātikas fakultātes. Novērošanas stacija atradās LVU Botāniskajā dārzā, kur bija iespējams veikt astronomiskos novērojumus. Lai kādas bija ieceres novērošanas stacijas attīstībai, studentu interese noplaka interešu trūkuma dēļ. Zemes mākslīgo pavadoņu novērošanas stacijas dežūru žurnāls Nr. 1, 1957–1958 pievienots atsevišķā datnē.

Selection analysis on the rapid evolution of a secondary sexual trait
2015
Evolutionary analyses of population translocations (experimental or accidental) have been important in demonstrating speed of evolution because they subject organisms to abrupt environmental changes that create an episode of selection. However, the strength of selection in such studies is rarely measured, limiting our understanding of the evolutionary process. This contrasts with long-term, mark–recapture studies of unmanipulated populations that measure selection directly, yet rarely reveal evolutionary change. Here, we present a study of experimental evolution of male colour in Trinidadian guppies where we tracked both evolutionary change and individual-based measures of selection. Guppie…
The quality of websites and their impact on economic performance: The case of nurseries and gardening companies in the Italian 'Mezzogiorno' regions
2014
The aim of this paper is to examine the quality of websites and the entrepreneurial perception of the importance of the website to improve the business performance in nurseries and gardening companies adopting web-marketing strategies. On this purpose, the paper firstly analyses which structural features enable a potential website to be labelled as 'good'; the awareness of these aspects is pivotal to define effective web-marketing solutions. Secondly, it examines whether the plant nursery entrepreneurs perceive the company website as a tool of additional sales able to increase the firm turnover. The results show that the websites are well framed and with a well-groomed design, but lacking i…
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…
