IDPlanT: the Italian database of plant translocation

2021

IDPlanT is the Italian Database of Plant Translocation, an initiative of the Nature Conservation Working Group of the Italian Botanical Society. IDPlanT currently includes 185 plant translocations. The establishment of a national database on plant translocation is a key step forward in data sharing and techniques improvement in this field of plant conservation. Supplemental data for this article is available online at https://doi.org/10.1080/11263504.2021.1985004.

Calcium mediated polyelectrolyte adsorption on like-charged surfaces.

2011

International audience; Monte Carlo simulations within the primitive model of calcium-mediated adsorption of linear and comb polyelectrolytes onto like-charged surfaces are described, focusing on the effect of calcium and polyion concentrations as well as on the ion pairing between polymers and calcium ions. We use a combination of Monte Carlo simulations and experimental data from titration and calcium binding to quantify the ion pairing. The polymer adsorption is shown to occur as a result of surface overcharging by Ca2+ and ion pairing between charged monomers and Ca2+. In agreement with experimental observations, the simulations predict that the polymer adsorption isotherm goes through …

Understanding prevention measures and tourist behavior in Croatia during the COVID-19 pandemic. A mixed-method approach

2022

This study investigates the adoption of prevention measures in Croatia during the COVID-19 pandemic and its relationship with tourist behavior. The research adopts a mixed-method approach as it examines both practitioners’ and tourists’ viewpoints. A qualitative study was conducted with eight destination service providers, while the quantitative study took place among 333 international tourists during their stay in the country. Results from the qualitative study show that the most frequently employed prevention measures are cleaning and disinfection of customer-use spaces, the use of hand sanitizers, mandatory face masks for employees and guests, and social distancing. Tourism service provi…

Multi-destination trips: a survey on incoming tourism in Sicily

2012

Many pleasure trips are often characterized by the visit of more than a single destination. Despite the topic is well documented in literature, the empirical studies are limited to a few pioneering studies. This lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviors, as it results, for example, from the system of European statistics on tourism (according to the Council Directive 95/57 EC), where no information on the average number of destinations visited within a single trip are provided. This paper aims to analyze the main implications of multi-destination trips both on tourism statistics and in tourism planning, and to describ…

Multi-destination pleasure trip behaviors in Sicily

2010

Many pleasure trips are often characterized by the visit of more than a single destination. The topic is well documented in literature (Cooper 1981; Mings & McHugh, 1992), but the main determinants and consequences of multi-destination trips have not been adequately analyzed (McKercher & Lew, 2004). Moreover, the empirical studies on this topic are limited to a few pioneering studies (Lau & McKercher, 2007; Mings & McHugh, 1992; Wu & Carson, 2008). This lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviors, as it results, for example, from European statistics on tourism (according to the Council Directive 59/95 EC), where no inf…

Environmental effects on the covariation among pace-of-life traits

2019

Pace‐of‐life syndromes (POLSs) are suites of life‐history, physiological and behavioural traits that arise due to trade‐offs between allocation to current and future reproduction. Traits generally show covariation that can arise from genetic and environmental influences on phenotypes and constrain the independent evolution of traits, resulting in fitness consequences and impacts on population dynamics. The notion that correlations among traits may vary among populations along environmental gradients suggests an important role for the environment in shaping and maintaining POLSs. However, no synthesis has been attempted of the myriad ways in which environmental factors should influence POLSs…

Diversification in evolutionary arenas - assessment and synthesis

2019

Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…

Applying the integrated trans-contextual model to mathematics activities in the classroom and homework behavior and attainment

2016

The aim of the present study was to test hypotheses of the trans-contextual model. We predicted relations between perceived autonomy support, autonomous motivation toward mathematics learning activities in an educational context, autonomous motivation toward mathematics homework in an out-of-school context, social-cognitive variables and intentions for future engagement in mathematics homework, and mathematics homework outcomes. Secondary school students completed measures of perceived autonomy support from teachers and autonomous motivation for in-class mathematics activities; measures of autonomous motivation, social-cognitive variables, and intentions for out-of-school mathematics homewo…
