Macroalgal assemblage type affects predation pressure on sea urchins by altering adhesion strength.
2010
In the Mediterranean, sea breams are the most effective Paracentrotus lividus and Arbacia lixula predators. Generally, seabreams dislodge adult urchins from the rocky substrate, turn them upside down and crush their tests. Sea urchins may respond to fish attacks clinging tenaciously to the substratum. This study is the first attempt to investigate sea urchin adhesion strength in two alternative algal assemblages of the rocky infralittoral and valuated its possible implication for fish predation. We hypothesized that (1) sea urchin adhesion strength is higher in rocky shores dominated by encrusting macro-algae (ECA) than in erected macro algae (EMA); (2) predation rates upon sea urchins are …
Resilience of Mediterranean Forests to Climate Change
2017
In the Mediterranean region, forests play a key role in the welfare of urban and rural peoples, by providing highly appreciated marketed goods as well as high value but nonmarket services. Anthropogenic climate change entails a significant impact on Mediterranean forests, such as the reduced species diversity, high density, pest, and diseases. In this chapter, we present the achievements of the project LIFE ResilForMed (Resilience of Mediterranean Forests to climate change), as Sicilian responds on adaptation and mitigation to climate change: (i) map of Sensitivity Forest Areas to desertification of the Sicilian region; (ii) list of bird indicators showing sensitivity to desertification in …
Feeding and management techniques to favour summer sheep milk and cheese production in the Mediterranean environment
2015
Sheep milk production in summer can lead to a diversification of milk products and to a more regular product distribution in the market throughout the year. However, in Mediterranean countries small ruminant production cycles are subjected to seasonal variations in forage resources. During summer, a key period for out of season production systems, nutrition plays a fundamental role in regulating the quantity and quality of milk production. In this review, feeding strategies and techniques that could be applied for out of season production in dairy ewes under different Mediterranean conditions are described for intensive, pasture-based and mixed systems. The most common feeding strategies us…
Novel strategies in the war against antibiotic resistance
2021
The global threat of antibiotic resistance is steadily growing. Antibiotic resistancemay involve any class of antibiotic, including second- and third-line agents that have been considered to date the last-resort drugs to counteract common infections. We may lose our capability to keep under control many common bacterial infections [1]. Despite this, in the past decade significant research efforts have been made to develop new antibacterial strategies able to treat multidrug-resistant infections; however, no new therapeutic approach has yet reached the clinic [2,3]. In order to identify new valuable antimicrobial drugs, it is important to consider the main bacterial resistance mechanisms in …
Therapeutic Strategies To Counteract Antibiotic Resistance in MRSA Biofilm‐Associated Infections
2021
Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as one of the leading causes of persistent human infections. This pathogen is widespread and is able to colonize asymptomatically about a third of the population, causing moderate to severe infections. It is currently considered the most common cause of nosocomial infections and one of the main causes of death in hospitalized patients. Due to its high morbidity and mortality rate and its ability to resist most antibiotics on the market, it has been termed a “superbug”. Its ability to form biofilms on biotic and abiotic surfaces seems to be the primarily means of MRSA antibiotic resistance and pervasiveness. Importantly, more tha…
Gender differences in technical-tactical behaviour of La Liga Spanish football teams
2021
[Abstract] The aim of this study was to identify differences in technical-tactical behaviour between the men and women first division football teams of the Spanish league, to this end 68 matches corresponding to 2016/17 season were analysed. A comparative analysis of the medians was carried out using the Mann-Whitney U-tests were conducted as post hoc tests. The size effect of this test was calculated and, finally, we performed a grouping of the variables through the clustering bootstrapping technique in both groups. We have detected statistically significant differences (p <0.01) regarding all accurate passes, in favour of men, as well as a greater number of yellow cards. In female footbal…
Measuring innovation in tourism from the Schumpeterian and the dynamic-capabilities perspectives
2012
This paper offers a diagnosis of the “state of the issue” regarding the measurement of innovation in the tourism industry at the company level, and some recommendations for overcoming identified problems. The study addresses two central issues: how existing secondary databases of innovative activity define the boundaries of the tourism industry, and the degree to which these databases reflect the particular characteristics of this economic activity. It is concluded that these analyses present serious biases and anomalies hindering the understanding of the situation at the micro level and complicating the issue of international comparability, and the analyses do not capture the internal hete…
Moderno BI un analītisko platformu īpašību izpēte
2018
Bakalaura darbs apskata moderno BI un analītisko platformu īpašības, ko piedāvā dažādi autori. Padziļināti tiek apskatīts Gartner uzņēmuma piedāvātais BI un analītisko platformu Maģiskais kvadrants, kas ar vairāku kritēriju palīdzību, iedala uzņēmumus 4 kategorijās: Līderi, Nišas spēlētāji, Redzētāji un Pretendētāji.

La reciente evolución de la estrategia antiterrorista, test de la estrategia global de seguridad de la UE
2017
This article focuses in the analysis of the European Common Security and Defence Policy’s evolution, specifically taking the European Global Agenda presented by the High Representative F. Mogherini in the European Council of June 2016 as the starting point. This strategy includes as a priority the fight against terrorism.

Antibiotics as selectors and accelerators of diversity in the mechanisms of resistance: from the resistome to genetic plasticity in the β-lactamases …
2013
Antibiotics and antibiotic resistance determinants, natural molecules closely related to bacterial physiology and consistent with an ancient origin, are not only present in antibiotic-producing bacteria. Throughput sequencing technologies have revealed an unexpected reservoir of antibiotic resistance in the environment. These data suggest that co-evolution between antibiotic and antibiotic resistance genes has occurred since the beginning of time. This evolutionary race has probably been slow because of highly regulated processes and low antibiotic concentrations. Therefore to understand this global problem, a new variable must be introduced, that the antibiotic resistance is a natural even…
