Perinatal exposure to 5-methoxytryptamine, behavioural-stress reactivity and functional response of 5-HT1A receptors in the adolescent rat.
2008
Abstract Serotonin is involved in a wide range of physiological and patho-physiological mechanisms. In particular, 5-HT1A receptors are proposed to mediate stress-adaptation. The aim of this research was to investigate in adolescent rats: first, the consequences of perinatal exposure to 5-metoxytryptamine (5MT), a 5-HT1/5-HT2 serotonergic agonist, on behavioural-stress reactivity in elevated plus maze, open field and forced swim tests; secondly, whether the behavioural effects induced by perinatal exposure to 5MT on open field and forced swim tests were affected by the selective 5-HT1A receptor agonist LY 228729, a compound able to elicit a characteristic set of motor behaviours on these ex…
Effects of pre- and postnatal exposure to 5-methoxytryptamine and early handling on an object-place association learning task in adolescent rat offsp…
2007
A reduction in 5-HT1A receptor response enhances learning and memory performance in rats. Pre- and postnatal treatment with 5-methoxytryptamine (5MT), a non-selective serotonergic agonist, and early handling, reduce the number of 5-HT1A receptors in neonatal and pre-pubertal rat progeny. The aim of this study was to investigate in adolescent male rats the consequences of pre- and postnatal treatment with 5MT and its interaction with early handling on an object-place association learning task, the "Can test", a motivated, non-aversive, spatial/object discrimination task. Results show that a single daily injection of 5MT from gestational days 12 to 21 (1 mg/kg s.c.) and from postnatal days 2 …
L’ipogeo P e le dinamiche insediative nel settore meridionale della città tra la tarda antichità ed il medioevo
2013
Si inquadra il progetto dell'ipogeo nel contesto delle trasformazioni subite dal settore meridionale della città di Agrigento nella tarda antichità. Si analizza quindi la la nuova funzione svolta dello stesso ipogeo in età medievale.
Agrigento. L’ipogeo P nella necropoli paleocristiana della Valle dei Templi. Ricerche 2005-2012
2013
Si presentano i risultati dello scavo e degli studi condotti su l'ipogeo P di Agrigento. Si tratta dell'unico ipogeo paleocristiano interamente indagato e studiato nell'ambito della collaborazione tra Università degli studi di Palermo e Parco archeologico e paesaggistico della Valle dei Templi. L'ipogeo ha avuto una lunga utilizzazione a scopo funerario dal Iv a tutto il VII secolo; quindi rientra nel processo di abbandono e distruzione del cimitero cristiano e di rifunzionalizzazione di alcuni spazi dello stesso per l'impianto di una officina ceramica medievale.
Cover crop management and water conservation in vineyard and olive orchards
2021
Abstract Sustainability in orchard crops is an important goal for farmers, decision-makers and consumers. The United Nations Sustainable Development Goals emphasize the importance of the soils in the Earth System to achieve sustainability and accomplish the Land Degradation Neutrality Challenge. Within the world agriculture land, olive and vineyards are within the eldest crops in the world, and they are also the ones with the highest degree of soil degradation. Cover crops (CC) are widely accepted as sustainable crop management that reduces soil and water losses, restores organic matter, increases biodiversity and fertility in degraded agriculture soils. The agriculture land must shift into…
Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests
2019
Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…
Gestione ecocompatibile delle infestanti nel finocchio da seme (Foeniculum vulgare Mill.)
2009
Nelle coltivazioni officinali, l'adozione di tecniche a basso impatto ambientale (tra cui la produzione in regime di agricoltura biologica) costituisce una scelta quasi obbligata per consentire al prodotto un'adeguata competitività sui mercati nazionali ed esteri. In quest'ambito, gli evidenti effetti che le infestanti esercitano sulla produzione e sui suoi parametri qualitativi pongono la gestione delle infestanti tra i principali nodi dell'agrotecnica delle colture officinali. Nel quadriennio 2004 -2007, il DAAT dell'Università di Palermo ha pertanto svolto una serie di sperimentazioni in campo tendenti a verificare l'efficacia contenitiva e gli effetti sulla coltura di alcune tecniche di…

Vil økt fysisk aktivitet kunne redusere andelen trygdemottakere? : En case-studie basert på deltakere ved Aktiv på dagtid, Aust-Agder
2018
Masteroppgave offentlig politikk og ledelse ME502 - Universitetet i Agder 2018 This study is based on Aktiv pådagtid as an case study. The purpose of this study is to investigate the relationship between increased participation in physical activities directed by Aktiv på dagtid and the participants status in relation to working life. To better understand the relationship between these two variables, the study include three possible predictors:health, social support and self-efficacy.Thisstudy use a paper-based survey with 144 respondents, which represent the participants atAktiv på dagtid, who are at theage between 16-70, receive social security benefits and resides in the municipalities of…
Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
