In summer 1979, the natural reproduction of oysters Crassostrea gigas Thunberg, in Marennes-Oleron basin, produced a large number of juveniles which was not the case in summer 1981. If one compares the evolution of the main constituents of the flesh, one can see that, at the beginning of August, before spawning the male oysters in 1981 contained 6,3% less proteins, 34,2% less lipids and 61,2% less glucids than those in 1979 and respectively 12,3%, 21,3% and 69,8% less as far as females are concerned. The energetic value of ash-free dry flesh of female oysters is nearly the same for the two years whereas for male oysters the value is slightly lower in 1981 than in 1979. The total energetic values of male and female oysters show a slight difference between...

Nutrition chez des copepodes en milieu lagunaire mediterraneen en fonction de la concentration en particules et de la temperature
Provedor de dados: 5
Autores: Gaudy, R; Pagano, M.
The zooplankton of an eutrophic brackish lagoon (Etang de Berre), near Marseille (France) was studied during an annual cycle. It was characterized by large populations of a pelagic copepod (Acartia tonsa ). Grazing on natural particles by this species was investigated. Adults were able to use an extended range of particle sizes, but showed selectivity for particles concentration was observed (14 mu m). Temperature and particles concentration appear to modify the selectivity behavior. Juvenile stages could also catch particles of various size but did not show the same selectivity for the peak particles as adults. Daily food ration was high comparatively to open-sea copepods. Taking into account several results obtained on food ration, egg production and...

Effects of density dependence, zooplankton and temperature on blue whiting     Micromesistius poutassou     growth
Provedor de dados: 5
Autores: Trenkel, Verena; Lorance, Pascal; Fassler, S. M. M.; Hoines, A. S.
Blue whiting Micromesistius poutassou mean total length at age in the north-east Atlantic Ocean was found to vary by around ±6% during the period 2004–2011 and mean mass at age by ±22% during the years 1981–2013. Linear modelling provided strong evidence that these phenotypic growth variations can be explained by trophic conditions, mainly negative density dependence and also food availability, and a negative long-term temperature effect on asymptotic siz

Provedor de dados: 81
Autores: Rodrigues,Flávio H.G.; Hass,Adriani; Lacerda,Ana C.R.; Grando,Raquel L.S.C.; Bagno,Marcelo A.; Bezerra,Alexandra M.R.; Silva,Wesley R.
The maned wolf feeds mainly on fruits and small vertebrates. The diet of maned wolf was studied at Águas Emendadas Ecological Station (AEES) through 328 faecal samples collected from November 1996 to August 1999. To evaluate the seasonal variation in food availability, the fruit phenology of the wolf's fruit, the main food item in maned wolf's diet, was monitored counting the fruits produced in 20 marked plants. Fructification phenology of fleshy fruit plants in the cerrado habitat of AEES was recorded monitoring five plots of 100 x 20 m , where the number of fruit producing species and individuals were recorded. The diet composition was 60% vegetal items and 40% animal ones. The wolf's fruit, other fruits and small mammals were the most frequent consumed...

Comparison of fish assemblages in two littoral habitats in a Neotropical morichal stream in Venezuela
Provedor de dados: 83
Autores: Montaña,Carmen G.; Layman,Craig A.; Taphorn,Donald C.
Morichales are lowland streams in South American savannas with riparian forest dominated by the moriche palm (Mauritia flexuosa). We sampled littoral habitats from ten flooded vegetated patches (dominated by Mauritiella aculeate) and six sand banks in two months of the dry season (Feb-Mar 2005) in a stream in the savannas of Apure State, Venezuela. We collected samples that compromised 12,407 individual fishes of 107 species. Small-bodied fishes (&lt; 100 mm), representing diverse trophic and life history strategies, were abundant. The most abundant species were in the families Characidae and Cichlidae. Fish assemblages from flooded vegetated patches differed significantly from those on adjacent sand banks. High structural complexity along vegetated...

Longitudinal use of feeding resources and distribution of fish trophic guilds in a coastal Atlantic stream, southern Brazil
Provedor de dados: 83
Autores: Wolff,Luciano Lazzarini; Carniatto,Natália; Hahn,Norma Segatti.
This study described the use of food resources and the distribution of fish trophic guilds along the longitudinal gradient of a coastal Atlantic stream, southern Brazil. Allochthonous resources (terrestrial insects) predominated in the headwaters, whereas autochthonous food items (algae, fish) and detritus predominated in the mouth section. Detritivorous, aquaticinvertivorous, and terrestrial- and aquatic-insectivorous species occurred throughout the gradient, while omnivorous and piscivorous in the headwaters and middle stretches, respectively, and herbivorous in the middle and mouth. Detritivores and aquatic-insectivores were significantly more specialized than the other guilds, however, there was no evidence of a longitudinal increase in trophic...

Using cyst material produced in an indoor cyst production system from 4 &lt;i&gt;Artemia&lt;/i&gt; strains belonging to the species &lt;i&gt;A. franciscana&lt;/i&gt; (San Francisco Bay, California, USA; Macau, Brazil; Great Salt Lake, Utah, USA) and &lt;i&gt;A. parthenogenetica&lt;/i&gt; (Lavalduc, France), different factors were studied that affect dormancy in brine shrimp cysts. Preliminary experiments under varying (a)biotic culture conditions revealed an interaction between environmental conditions and hatching characteristics. Results obtained under better-defined conditions demonstrated a significant positive correlation between the amount of food available to the adult &lt;i&gt;Artemia&lt;/i&gt; populations and the hatchability of their encysted...

A Global Hunger Index: Measurement Concept, Ranking of Countries, and Trends
Provedor de dados: 31
Autores: Wiesmann,   Doris M.
Progress in combating hunger and undernutrition has been lagging for decades. Best practices to fight hunger and undernutrition have been available for a long while, but lack of political will among leaders and a lack of political power among the poor have hampered their implementation. Since indices have proven to be powerful tools for advocacy and are able to capture multifaceted phenomena, the Global Hunger Index (GHI) was developed to increase attention to the hunger problem and mobilize the political will to speed up urgently needed progress in the fight against hunger. The GHI captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality, which is to a large extent...

Commercialisation of Agriculture in Kenya: Case Study of Urban Bias on Food Availability in Farm Households
Provedor de dados: 31
Autores: Kiriti,   Tabitha; Tisdell,   Clement A.
This study investigates the effect of cash cropping on food availability and examines the determinants of the proportion of income allocated for food expenditures in the Nyeri district in Kenya. Using a Tobit model, the results suggest that in general food expenditure allocations suffer due to cash cropping in Kenya as the lump-sum income flows from this may be used for purchases other than food. Food expenditure also suffers when remittances are irregular. On the other hand, earnings from outside employment for married women living with husbands are positively associated with food expenditure allocations. Amounts of non-cash food output as well as ownership of livestock are negatively associated with food expenditure allocations. These findings indicate...

With high food prices threatening the food security of millions of vulnerable households around the world, hunger and malnutrition are back in the headlines. The world is making only slow progress in reducing food insecurity, according to the Global Hunger Index (GHI). Some regions—in particular South and Southeast Asia, the Near East and North Africa, and Latin America and the Caribbean—have made significant headway in combating hunger and malnutrition since 1990, but in South Asia and Sub-Saharan Africa, the GHI remains high. Moreover, progress in Sub-Saharan Africa since 1990 has been marginal. The GHI is a tool developed by IFPRI for regularly tracking the state of global hunger and malnutrition. This year’s index reflects data until 2006—the most...

Commercialisation of Agriculture in Kenya: Case Study of Policy Bias and Food Purchases by Farm Households
Provedor de dados: 31
Autores: Kiriti,   Tabitha; Tisdell,   Clement A.
This study considers the effect of cash cropping on food availability and investigates the determinants of household food expenditure as a proportion of gross income relying on a sample of rural households in the Nyeri district of Kenya. Results from an application of a Tobit model suggest that household food purchases and food availability may suffer as a consequence of increasing cash cropping in Kenya. Husbands favour commercial crops and, it seems, favour non-food purchases. Married women living with their husbands use proportionately less of their gross income to purchase food compared to unmarried women and to those women not living with their husbands. Male bias in food purchased is present, and is exacerbated when payment for cash crops is lumpy....

Does Healthy Food Cost More in Poor Neighborhoods? An Analysis of Retail Food Cost and Spatial Competition
Provedor de dados: 31
Autores: Hatzenbuehler,   Patrick L.; Gillespie,   Jeffrey M.; O'Neil,   Carol E.
The organization of the Baton Rouge, Louisiana, retail food industry was analyzed to determine whether spatial competition influenced the cost and availability of food items. Using a spatial competition gravity variable, the costs of two separate market baskets were analyzed in January 2009, and the factors influencing spatial competition were determined. Store type (chain or supercenter) was found to be the most significant determinant of food costs, validating findings of past studies. Although food was not found to be more expensive in low-income areas, results suggest that residents in low-income and rural areas have disincentives to purchase affordable, available healthy food due to the spatial organization of their local food market.

Use of the space by the opossum Didelphis aurita Wied-Newied (Mammalia, Marsupialia) in a mixed forest fragment of southern Brazil
Provedor de dados: 104
Autores: Cáceres,Nilton Carlos.
Use of the space by the opossum Didelphis aurita Wied-Newied, 1826 (Mammalia, Marsupialia) in a mixed forest fragment of southern Brazil. The space use of the marsupial Didelphis aurita was studied in a forest fragment of southern Brazil from February 1995 to January 1996. The method used was the 'distribution utilization' in which each trap was set in 38 x 38 m quadrats. Captures of each marked individual in each point give information on its habitat use. Food availability was searched and compared to the habitat utilization and to the food consumption of opossums. Distribution patterns of captures (aggregated to random) and spatial overlap between individuals were searched. Results showed aggregated distributions of individuals, particularly females, in...
