| In order to have a better understanding of recessing in great scallop, Pecten maximus and consequently the causes of mortality at reseeding, this study has monitored, at different seasons, the dispersion and recessing of different sizes of juveniles (about 15, 30 and 45 mm, called small, medium and large) after seeding. Moreover, the aim was to see when small spat (15 mm) could be seeded, and thus reduce the costs of intermediate culture. Three monitoring approaches were used together: (1) continual observations by remote video camera, of a defined area (less than 1 m2) containing 10 scallops from each size group; (2) daily monitoring of behaviour with divers along three bottom lines, with 20 × 1 m2 plots each and nine marked scallops per plot; and (3) the... |

| Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest conditions on the final quality of mango. Considerably less attention has been paid to the influence of environmental factors on mango growth, quality traits, and postharvest behaviour. In this paper, we provide a review of studies on mango showing how environmental factors influence the accumulation of water, structural and non-structural dry matter in the fruit during... |

| In tropical littoral environments, suspended organic matter favors the presence of sessile filter feeder organisms such as sponges, over those predominantly phototrophic such as algae and corals. In the Santa Marta area in the Colombian Caribbean, productivity is enhanced by alternating pulses of coastal upwelling and continental runoff, resulting in an important diversity and abundance of sponges. Species of the genus Ircinia ( I. campana, I. felix and I.strobilina) are conspicuous and abundant in the rocky and reef biotopes of the area. To establish the influence of predominant environmental conditions on the distribution of these three species, their density, size and microhabitat preference, their form and color, the occurrence of predation signs, the... |

| Background Life in the darkness of caves is accompanied, throughout phyla, by striking phenotypic changes including the loss or severe reduction in eyes and pigmentation. On the other hand, cave animals have undergone constructive changes, thought to be adaptive, to survive in this extreme environment. The present study addresses the question of the evolution of growth in caves, taking advantage of the comparison between the river-dwelling and the cave-dwelling morphs of the Mexican tetra, Astyanax mexicanus. Results A sclerochronology approach was undertaken to document the growth of the species in these two very distinct habitats. Scales from 158 wild Astyanax mexicanus specimens were analyzed from three caves (Pachón, Tinaja and Subterráneo) and two... |

| The aim of this study was to determine the chemical composition and fatty acids profile present in Argentine anchovy (Engraulis anchoita) northern population as a function of fish size and fishing area (SW Atlantic Ocean, Argentine Sea). Samples were collected during the northern stock assessment cruise of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) carried out on board of FRV Capitán Oca Balda in Spring 2008 (OB-02/2008). The fishing trawls were performed between 34º 35' S and 40º 19' S. The area was divided in two zones: the northern, between 34º S-38º S, strongly influenced by the mixohaline waters of the Río de la Plata River estuary and the southern, between 38º S-41º S, that included the El Rincón coastal area. In each... |

| Le peuplement de démosponges des îles Kerkennah a été étudié notamment du point de vue de sa répartition systématique et comparé à d’autres peuplements de démosponges de l’étage infralittoral méditerranéen. La récolte a intéressé 111 individus à partir de 11 stations différentes situées sur les hauts fonds des îles Kerkennah à des profondeurs variants entre 0,5 et 12 m, principalement des stations d’herbiers à posidonies. Nous avons pu identifier 50 espèces différentes, parmi lesquelles 19 étaient signalées pour la première fois en Tunisie, et 2 étaient nouvelles pour la Méditerranée. Parmi ces 50 espèces, 8 seraient nouvelles pour la science: Timea sp1 ; Timea sp2 ; Batzella sp ; Clathria (Microciona) sp1 ; Clathria (Microciona) sp2 ; Clathria sp ;... |

| Se propone determinar la talla de primera madurez (LC50) en la langosta Panulirus argus, a partir de las setas ovígeras con estadio III, comparando el resultado obtenido con el LC50 hallado a partir de la presencia de hueva y/o espermatóforo. La información provino de muestreos mensuales llevados a cabo desde abril de 2007 hasta marzo de 2008 en el Golfo de Batabanó, región suroccidental de Cuba, donde se seleccionaron las siete zonas de monitoreo de La Coloma. De un total de 6 238 langostas hembras muestreadas, se identificaron los estadios de las setas en 5 232. El LC50 se determinó por el ajuste de una curva logística a las frecuencias de talla acumuladas relativas, resultando que los valores del LC50 calculados para hembras con setas en estadio III... |

| The structure of estuarine fish assemblages at temperate latitudes in Patos Lagoon (32º05'S, 52º04'W), Rio Grande do Sul, Brazil and York River (37º17'N, 76º33'W), Virginia, USA was compared using mid and late 1970's data from bottom trawl collection to investigate whether geographically isolated fish assemblages have similar ecological structure given similar latitudinal positions on the warmtemperate southwestern and northwestern Atlantic regions, respectively. Since estuarine species often exhibit an ontogenetic shift in habitat requirements or preferences we examined Capture per Unity of Effort by size class (CPUE-SC) and split species into "size ecological taxa" (SET) for analysis. The use of CPUE-SC also allowed the abundance of a SET to be computed... |

| The effect of moisture content on some physical properties of Bush Mango (Irvingia gabonensis) nut was studied at four moisture levels in the range of 7.52% - 20.6% (d.b). Results showed that the length, width and thickness of nut increased from 37.84 to 50.16 mm, 30.23 to 42.62 mm and 19.25 to 28.15 mm respectively, as moisture content increased in the above range. Nut sphericity decreased from 76.2% to 69.5% as moisture content increased. One thousand seed weight, bulk density, true density and angle of repose increased from 6.634 to 9.158 kg, 756.7 to 1095 kgm-3, 984.4 to 1095kgm-3 and 25.3 to 38.9o respectively, in the above moisture range. Static coefficient of friction on different surfaces increased in the order of fiber glass (0.378 to 0.394),... |

| Firstly, the paper establishes a brand-extension size model and adopts the marginal analysis to analyze the optimal solution of it. Secondly, research the brand-extension condition of G brand by questionnaire survey. There are 240 questionnaires handed out, with 211 withdrawing and 187 valid, by doing this to test the influencing degree of each factor in brand-extension size model; At the same time, use analytic hierarchy process to analyze the size of brand extension and principal component analysis to find out the main factors that influence brand extension of G brand. Finally, the paper makes an empirical analysis on brand extension size model based on ecological characteristics, the results show that the order of the total information reflected by each... |
