Une envahissante dans le paysage : cas de l’ambroisie à feuilles d’armoise

2014

L’ambroisie à feuilles d’armoise (Ambrosia artemisiifolia L.) est une espèce annuelle envahissante introduite en France à la fin du XIXe siècle. Plante rudérale, tolérante à de nombreux stress, l’ambroisie se développe essentiellement dans les habitats perturbés. Les principaux milieux occupés sont les parcelles agricoles, les bords de route et les zones perturbées par les activités anthropiques (jachères industrielles, zone de dépôt de matériaux …). Les berges de rivière constituent le seul habitat naturel dans lequel l’ambroisie peut former d’importantes populations. La semence d’ambroisie n’a pas de structure particulière favorisant son invasion. Trop lourde pour être dispersée par le ve…

A casual alien plant new to Mediterranean Europe: Ceiba speciosa (Malvaceae) in the suburban area of Palermo (NW Sicily, Italy)

2014

The abiotic and biotic characteristics of the first sites where floss silk tree behaves as a casual alien plant in the Mediterranean Europe are described. The species was probably first planted in botanical gardens of southern France few decades before mid XIX century. It was introduced in Palermo in 1896, a city which appears to match very well its climatic requirements. According to the available information on its biology and ecology in both its original and secondary range, the floss silk tree should not become an invasive alien plant in the Mediterranean. Nevertheless, several gaps need to be filled in order to increase our understanding of future trends of Ceiba speciosa in southern E…

Substratum recognition as settlement cue for larvae of Dendropoma cristatum (Biondi, 1859)

2017

Despite the ecological relevance of the vermetid bioconstructions in the Mediterranean, little is known about the early life stage of Dendropoma cristatum. This study describes the preference for settlement substrata from D. cristatumlarvae. A field experiment was carried out to test the suitability of crustose coralline algae (CCA), D. cristatumadults and two inorganic substrata as settlement surfaces. The number of settling larvae varied among the four treatments with higher settlement success on organic surfaces. CCA and D. cristatumindividuals seem to promote attachment of young larvae and to induce the metamorphosis in recruits. This is probably due to biological or physical properties…

Human olfactory communication: current challenges and future prospects

2020

Although anthropologists frequently report the centrality of odours in the daily lives and cultural beliefs of many small-scale communities, Western scholars have historically considered the sense of smell as minimally involved in human communication. Here, we suggest that the origin and persistence of this latter view might be a consequence of the fact that most research is conducted on participants from Western societies who, collectively, were ratherold(adults),deodorizedanddesensitized(ODD) to various aspects of olfactory perception. The view is rapidly changing, however, and this themed issue provides a timely overview of the current state-of-the-art on human chemocommunication. Based …

Evaluation of the Burden of HPV-Related Hospitalizations as a Useful Tool to Increase Awareness: 2007–2017 Data from the Sicilian Hospital Discharge …

2020

In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = &minus

Publish or perish. This saying clearly exemplifies that science communication is vital for scientists, research bodies and nation competitiveness. Nowadays both computers and internet have deeply changed the way scientific articles are written and published. In an editorial world moving at accelerated pace, scientists are eager to get their papers published in the best journals because impact factors are ruling careers and funding. Since fundings are provided by various public and private bodies, scientific papers should be partly understandable by a wide audience from journalists to entrepreneurs, political leaders and the general public. However, as an editor of scientific journals, I obs…

Scientific writing for impact factor journals

EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
