Landscape Socioecology in the Serpis Valley (10,000–4000 BP)
2008
En este trabajo se discute nuestro enfoque de la modelización del paisaje para la cuenca del Serpis medio (costa mediterránea central de la Península Ibérica) durante el Holoceno. La secuencia arqueológica de estos valles está marcada por la aparición inicial del paquete neolítico alrededor del año 5700 a.C. Examinamos cómo los paisajes responden al modo de vida agrícola, tanto a corto como a largo plazo. Conceptos como el cambio, la adaptación y también la resiliencia proporcionan marcos conceptuales para comprender mejor la forma en que los seres humanos interactúan con su entorno. También ayudan a explicar cómo fenómenos como la introducción inicial de la horticultura simple de cereales …
La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo
2023
Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…
Conservation of Ptilostemon greuteri (Asteraceae), an endemic climate relict from Sicily (Italy): state of knowledge after the discovery of a second …
2022
Ptilostemon greuteri is one of the most endangered and poorly studied woody vascular plant species of the Mediterranean Basin, endemic to Sicily (Italy). Several peculiar traits confer to P. greuteri a character of uniqueness and an enigmatic attractiveness. In fact, at first glimpse the largest individuals of this species remind the most remarkable and peculiar cases of herbaceous genera (e.g., Echium, Senecio) turned woody on insular or insular-like mountain ecosystems. Following the discovery of a second population of this rare species, a project aiming at the study and conservation of P. greuteri was set up. We present here updated information on the distribution, conservation status, b…
Quantitative studies of bird movement: a methodological review
1999
The past several years have seen the development of a number of statistical models and methods for drawing inferences about bird movement using data from marked individuals. It can be difficult to keep up with this rapid development of new methods, so our purpose here is to categorize and review methods for drawing inferences about avian movement. We also outline recommendations about future work, dealing both with methodological developments and with studies directed at hypotheses about bird movement of interest from conservation, management, or ecological perspectives.
Early stages of beta2-microglobulin aggregation and the inhibiting action of alphaB-crystallin
2008
The interest of nucleation of protein crystals and aggregates (including oligomerization) spans from basic physics theory all the way to biophysics, nanophysics, clinical sciences, biotechnologies, food technologies and polymer-solvent interactions. Understanding nucleation within a theoretical framework capable of providing quantitative predictions and control of nucleation rates, or even the very occurrence of crystallization, is a long-sought goal of remarkable relevance to each of the above fields. A large amount of work has been aimed at such goal, but success has been so far rather limited. Work at our laboratory has more recently highlighted a direct link between nucleation rates and…
The Resilience of the Valley of Temples Among Natural Calamities and Social Disaster
2017
Preservation of the cultural heritage, intended as common patrimony, is a cultural achievement that in territories like Sicily, which has often suffered the lack of legality, is the result of a difficult process of implementation. Cultural heritage is not ruined exclusively by natural calamities: damages caused by social and cultural disasters may at times be even more devastating. The archeological park of Agrigento, born in 1947 after a natural disaster (a landslide in 1944), hides a history of a half century of battles between the illegal land use and legislative measures to protect a cultural heritage recognized worldwide (registered in the WHL in 1997). After fifty years of attacks aga…
Le statut des couleurs et de la lumière dans les munāẓarāt paysagères au Yémen à l’époque post-classique
2018
Abstract This contribution aims to comment on chromaticism by analysing the principal colours as they are mentioned in the landscape descriptions of the maqāmāt of the type munāẓarāt composed in the Yemen of the post-classical era. The colours are mainly manifested in the depictions of the garden area, but can also be characterising of certain vegetal types that sometimes play the main role in these texts. The analysis of the colours enables us to make certain considerations about the state of light and its depictions within this corpus. Indeed, there appears to be a direct correlation in these descriptions between the light and the luminosity characterised by its type of reflection and bri…

Manipulative parasites may not alter intermediate host distribution but still enhance their transmission: field evidence for increased vulnerability …
2013
SUMMARYBehavioural alterations induced by parasites in their intermediate hosts can spatially structure host populations, possibly resulting in enhanced trophic transmission to definitive hosts. However, such alterations may also increase intermediate host vulnerability to non-host predators. Parasite-induced behavioural alterations may thus vary between parasite species and depend on each parasite definitive host species. We studied the influence of infection with 2 acanthocephalan parasites (Echinorhynchus truttae and Polymorphus minutus) on the distribution of the amphipod Gammarus pulex in the field. Predator presence or absence and predator species, whether suitable definitive host or …
