Since 2008, a severe decrease in size and body condition together with a demographic truncation has been observed in the sardine (secondarily in anchovy) population of the Gulf of Lions (NW Mediterranean Sea). In parallel, sprat biomass, which was negligible before, has increased tenfold. All of these changes have strongly affected the regional fisheries. Using trophic and isotopic data from contrasting periods of low versus high growth and condition, we investigated potential changes in diet and interspecific feeding interactions through time. Evidence of resource partitioning was found between sprat and both anchovy and sardine in 2004 and 2005. Since 2010, the isotopic niches of the 3 species have tended to overlap, suggesting higher risk of competition for food resources. Moreover, the wider trophic niche of sprat indicates higher variability in individual diets. Anchovy and sardine diet varied through time, with a high proportion of large copepods or cladocerans in periods of high growth and condition (1994 and 2007, respectively) versus a dominance of small copepods in the present (2011−2012). Further-more, an important reduction in prey diversity was also identified in the diet of both anchovy and sardine during the most recent period. Our results support the hypothesis that changes in small pelagic fish growth, size and body condition and ultimately biomass could be due to bottom-up control characterized by changes in food availability and increasing potential trophic competition.

Poly-cultures are cropping systems using multiple crops in the same space and time, avoiding large stands of sole crops, hence contributing to reconciliation ecology. These land uses have several advantages over monocultures, e.g. increased biodiversity and diversification of agricultural production. Coupled with soil conservation measures, they also contribute to erosion control and resource protection in fragile areas. The viability of such systems often depends on their efficiency under limited resource conditions, which in turn makes them acceptable among the farming community. Most farmers, however, are reluctant to adopt such systems because they may compete for water and nutrients. This study was conducted during 2011 on the Queen Sirikit research farm, Ban Bo Wi village, Ratchaburi province, in North-West Thailand to investigate the competition in maize based soil conservation systems. The soil at the field site ranged from an endoleptic Alisol to ahyper skelletic Leptosol. The treatments were maize under farmer's practice (control) and maize-chili intercropping combined with alley cropping of Leucaena under minimum tillage and Jack bean relay cropping with and without fertiliser application. Plot size was 4 m by 13 m and slope of 18-20%. We used both carbon isotopic discrimination and electrical resistivity tomography (ERT) imaging, a novel non-invasive method, to understand and distinguish the competition for water and nutrients in tropical field conditions. A negative relationship was observed between 13C isotopic discrimination and total nitrogen in grain with R2 ranging from 0.63 (p ≤ 0.01) to 0.70 (p ≤ 0.001) while a positive correlation was found between total nitrogen in grains and total dry matter production with R2 ranging from 0.51 (p ≤ 0.04) to 0.84 (p ≤ 0.001). Nutrient competition induced an increase in δ13C values in maize rows close to Leucaena hedgerows and decreased their total dry matter production. ERT imaging showed different water depletion patterns during the growing season, directly linked with the growth and development of maize such as leaf area index, plant height and canopy cover. This helped explaining the impact of hedgerows on crop growth and yields in maize rows adjacent to the hedges, leading to various spatial patterns along the slope. [less ▲]

Migration issues are often thought and debated in terms of societal security. The association of migration with a series of social ills such as crime, urban disorder, unemployment, etc. in the mass media and in some political statements is common to many countries. In these conditions, the task of social and political scientists is very delicate and complex, as they are asked to produce objective knowledge about a highly politicised set of issues. Could their work not contribute to the over-dramatisation of migration, even though their aim may be exactly the opposite? Is there not a risk for the results of their work to be misinterpreted in order to fit political strategies? [less ▲]

The present study focused on the nature of the reading disability of children with both dyslexia and inhibition deficit. Van der Schoot et al. (2000; 2004); Nossent et al. (2005); Nossent and Deroux (2006) showed that these children tended more to guess the words they read because these “guessers” found difficulties in suppressing false candidate words that are activated in the lexicon. To test this account, dyslexic children with and without inhibition deficit were presented a sentence reading task. To evoke guessing, each sentence contained a word or a pseudoword which closely resembled either a valid congruent or incongruent word. Our hypothesis was that dyslexic children with inhibition deficit guessed more the word they read from the sentence context and the global word form than dyslexic children without inhibition deficit. The results showed that both dyslexics with and without inhibition deficit tended more to guess the words than control children without dyslexia and inhibition difficulties. We discussed these results with the fact that most of children with reading difficulties use the sentence context to compensate for poor reading skills. [less ▲]

Given the present state of our knowledge, the question about the links between Egyptian and Greek medicine is far from being resolved. Some convergences can in fact be detected, but when you study them further, you will find that they reveal a loan, or a simple coincidence, or else a false interpretation of the sources. At the end of the sixth century BC, Pharaonic medicine was outclassed and influenced little by little by Greek medicine. Lastly, the Coptic medical treatises, composed in Egyptian language, but written in Greek characters, combine some Greek and finally Arabic borrowings. [less ▲]

An uncoupling protein was recently discovered in plant mitochondria and demonstrated to function similarly to the uncoupling protein of brown adipose tissue. In this work, green tomato fruit mitochondria were purified on a self-generating Percoll gradient in the presence of 0.5% bovine serum albumin to deplete mitochondria of endogenous free fatty acids. The uncoupling protein activity was induced by the addition of linoleic acid during the resting state, and in the progressively uncoupled state, as well as during phosphorylating respiration in the presence of benzohydroxamic acid, an inhibitor of the alternative oxidase and with succinate (+ rotenone) as oxidizable substrate. Linoleic acid strongly stimulated the resting respiration in fatty acid-depleted mitochondria but had no effect on phosphorylating respiration, suggesting no activity of the uncoupling protein in this respiratory state. Progressive uncoupling of state 4 respiration decreased the stimulation by linoleic acid. The similar respiratory rates in phosphorylating and fully uncoupled respiration in the presence and absence of linoleic acid suggested that a rate-limiting step on the dehydrogenase side of the respiratory chain was responsible for the insensitivity of phosphorylating respiration to linoleic acid. Indeed, the ADP/O ratio determined by ADP/O pulse method was decreased by linoleic acid, indicating that uncoupling protein was active during phosphorylating respiration and was able to divert energy from oxidative phosphorylation. Moreover, the respiration rates appeared to be determined by membrane potential independently of the presence of linoleic acid, indicating that linoleic acid-induced stimulation of respiration is due to a pure protonophoric activity without any direct effect on the electron transport chain.

This study aimed at verifying if the hypothesis that one day at 60 °C is equivalent to one month at 20 °C could be confirmed during linseed oil aging for 6 months at 20 °C and 6 days at 60 °C using the “Schaal oven stability test”. Tests were conducted with linseed oil supplemented or not with myricetin or butyl-hydroxytoluene as antioxidants. Oxidation was evaluated with the peroxide and p-anisidine values, as well as the content in conjugated dienes and aldehydes. All four indicators of oxidation showed very different kinetic behaviors at 20 and 60 °C. The hypothesis is thus not verified for linseed oil, supplemented or not with antioxidant. In the control oil, the conjugated dienes and the peroxide value observed were respectively of 41.8 ± 0.8 Absorbance Unit (AU)/g oil and 254.3 ± 5.8 meq. O2/kg oil after 6 months at 20 °C. These values were of 18.2 ± 1.3 AU/g oil and 65.2 ± 20.3 meq. O2/kg after 6 days at 60 °C. [less ▲]

In the beginning of the 16th century, the princes of the House of Burgundy-Habsburg, Philip the Fair and his son Charles, travelled several times to Spain. These travels radically transformed the scope of their political possibilities. Philip became king consort of Castile, along with his spouse Joanna, while Charles, as heir to the Catholic Kings, seized the crowns of all the Spanish Kingdoms. At least since the second half of Philip the Good’s reign, the main political objective of the rulers of the Low Countries was the acquisition of a royal title, dignity, and power. This paper examines how, at a time when such a crown was in their reach, the courtly authors of Philip the Fair and Charles of Habsburg wrote elaborate travel accounts of their masters’ journeys to Spain. In their narrations, they created a royal figure and image that legitimated their masters’ place in their new function. They also established a new distinctive model of monarchy, which they inscribed at the crossroads of the political actions of the Dukes of Burgundy and those of the Catholic Kings. Furthermore, they connected this type of kingship to what they considered to be the main political forces of Spain: the Grandees and the Spanish Cortes. Lastly, their narratives capture a time of intense reflection on monarchical politics in the Low Countries shortly before the Imperial Election of Charles v redesigned the political landscape.

A novel class of surface-active carbohydrate esters is prepared by a two-step strategy that takes advantage of the selectivity of enzymatic catalysis and the versatility of the thiol-Michael addition reaction. The surfactant performance of the produced aliphatic, fluorinated and silicon based sugar esters are evaluated by surface tension measurements. The novel thiolated mannose, made available in this work, appears as a powerful building block for the incorporation of unprotected sugar moieties into complex molecules. [less ▲]
