Review of immediate cardiac response in intertidal gastropods limpets at varying temperature, salinity and air exposure
2009
In 1990 Depledge and Andresen developed a #eld/laboratory, non-invasive technique to monitor the immediate response of cardiac activity in bivalves. Since then, several researchers have experienced and tested the variability of heart beat rate (HBR)and of associated metabolic rates under di$erent conditions in intertidal molluscs. Review of HBR immediate response in acute exposure and acclimation to changes of salinity, thermal stressors and air exposure were examined to test di$erent hypothesis. In intertidal Mediterranean and tropical limpets, the decrease in metabolic rate with a decrease in salinity was di$erent in animals experiencing di$erent degrees of salinity !uctuation in their re…
Local food availability affects invasion ability of alien bivalves: an experimental and simulation integrated approach
2009
The Lessepsian bivalve Brachidontes pharaonis is considered as one of 100 worst invasive species in the Mediterranean rapidly colonizing the most part of the Basin. Its current distribution seems primarily due to ship transport of carrying larvae by ballast waters and/or in the fouling attached beneath the ship-keels. Although humanmediated transport seems to potentially in!uence dispersal of invasive species, habitat suitability, temperature, salinity and food availability (i.e. in terms of quality and quantity of organic matter) seem to represent decisive factors in determining survivorship and distribution of this species. Physiological tolerance of B. pharaonis to temperature and salini…
Heart beat rate: a physiological response to thermal stress in blue mussels species.
2009
Non-native species often have ecological impacts on invaded communities. The quanti#cation of features of invaders and recipient ecosystems facilitating and/or interfering with successful invasion remains a challenge because of several factors may in!uence the success of invasions. Among them, life history strategies (e.g., reproductive potential, body size), ability to avoid predators, disease resistance and physiological compensatory mechanisms to adapt to changing habitats are among the most important factors. The latter has been often invoked as the key to success for many intertidal invasive invertebrates and have been suggested as key indicators of invasibility rate and the ultimate d…
Scope for Growth of the intertidal Lessepsian bivalve Brachidontes pharaonis (Fischer 1870) at varying environmental variables
2009
The concept of energy available to organismal growth (i.e. scope for growth; SFG) assumes a central role in studying the behaviour of successful invaders in aquatic habitats: the higher the energy allocated to growth and reproduction, the greater the likelihood of stability/persistence in space over time of aquatic populations. When successful invaders find useful life conditions (i.e., allowing to reach maximum SFG), they compete for space and resources with indigenous species, altering the functioning of entire ecosystems. The Indo-Pacific bivalve Brachidontes pharaonis offers an excellent model for the study of “Lessepsian migration” and the successive colonization at new Mediterranean l…
Identifying suitable proxies for climate change impacts in shallow Mediterranean habitats: sponge filtration not a ready-to-use tool yet
2009
The identi#cation of reliable proxies is crucial to undertake experimental manipulation and test hypotheses on climate change impacts. We evaluated the potential use of sponge #ltering activity as a proxy for the e$ect of temperature (T) increase in shallow marine habitats since: i) Porifera are ubiquitous, sessile and long-lived aquatic organisms; ii) Porifera are active #lter feeders and play a key-role in benthic-pelagic coupling; iii) #ltering activity already proved reliable to detect T e$ects on bivalves. The systematic screening of current literature to gather data and test the assumption “T increase -> increase in sponge #ltering activity” led to a #rst list of 840 sources (title re…
Determination of basic strenght of aliphatic amines through ion pair formation in some ionic liquid solutions
2010
To have an evaluation of the basic strength of aliphatic amines in ionic liquid solution, the stability constants relevant to the formation of amine/p-nitrophenol ion pairs were determined in different ionic liquids at 298 K. In particular, aliphatic (pyrrolidinium) and aromatic (imidazolium) ionic liquids were used. Imidazolium ions, bmim(+) and bm(2)im(+), having different hydrogen bond donor abilities were taken into account. Anions were chosen ([BF(4)(-)], [PF(6)(-)], and [NTf(2)(-)]; where NTf(2) = bis(trifluoromethansulfonyl)imide) showing different shape, size, and coordination ability. Several primary, secondary (cyclic or not), and tertiary amines were used to study the effect of a…
Does the journalistic photograph need a context? : Rethinking contextual interpretation
2017
In times when photojournalists experiment with various forms of visual production and journalistic photographs are disseminated not only in the press, but at the photography festivals and in museums, the question about the role of context in photography interpretation should be revisited. Thus, this study provides critical review of the contextual interpretation of journalistic images, focusing on the production, medium and page context. The context of production is discussed here by referring to the quantitative content analysis and iconological context analysis. The context of medium determines the perception of photographs and provides a particular page context, usually limited to the ca…
Interpretation of journalistic photographs as an instrument of visual literacy education
2016
Images are produced, used and distributed on an enormous scale. However, the skills of understanding, interpreting and using images as well as thinking and learning in terms of images are taken for granted, and thus, they are not sufficiently taught and developed, especially in higher education. The need for introducing visual literacy into the curriculum was identified in late 1960s, but no concrete guidelines have followed. This study proposes to apply interpretation of journalistic photographs as an instrument of visual literacy education. The main focus is on the image interpretation process and the kinds of meanings viewers apply to a photograph in the interpretation process. In each o…
"It is time for the British people to have their say" : The Daily Mail and the Guardian on Brexit from 2013 to 2016
2017
Yhdistyneiden kuningaskuntien kansanäänestys Euroopan Unionista lähtemiseksi kesäkuussa 2016 oli monella tavalla järisyttävä, jopa odottamaton, tapahtuma. Yleisenä oletuksena oli, että vuoden 1975 kansanäänestyksen tulos toistuisi ja Yhdistyneet kuningaskunnat pysyisivät edelleen Euroopan Unionin jäsenmaana maassa pitkään vallinneesta euroskeptisyydestä huolimatta. Tämän tutkielman tarkoitus on tarkastella, miten Brexitin keskustelluimmat teemat kuten maahanmuutto, talous ja identiteetti kehittyivät vuosina 2013-2016 lehdissä the Daily Mail ja the Guardian sekä miten nämä teemat vaikuttivat Brexitin kokonaiskuvaan lehdissä. Tarkastelun kohteena on myös, miten nämä lehdet vaikuttivat lukijoi…
Hahmojen välisiä suhteita : interfiguraalisuus Donna Tarttin romaanissa The Secret History
2017
Tutkielma käsittelee interfiguraalisuutta – intertekstuaalisuuden alalajia, joka viittaa eri teksteissä esiintyvien henkilöhahmojen välisiin suhteisiin – Donna Tarttin romaanissa The Secret History. Tarttin romaanin päähenkilöitä tarkastellaan suhteessa neljän muun romaanin henkilöhahmoihin (F. Scott Fitzgeraldin The Great Gatsby, William Goldingin Lord of the Flies, Evelyn Waugh’n Brideshead Revisited sekä Oscar Wilden The Picture of Dorian Gray). Tutkielmassa eri teksteissä esiintyvien henkilöhahmojen välisiä interfiguraalisia kytköksiä peilataan suhteessa The Secret Historyn kertojan luotettavuuteen ja romaanin keskeisiin teemoihin. Tutkimusongelmana on, millaista potentiaalia interfigur…
