| Survival, growth and fatty acid composition of Ostrea edulis larvae (L.) fed four different single species, microalgal diets, Tisochrysis lutea (T), Chaetoceros neogracile (Cg), Skeletonema marinoi (Sm) or Tetraselmis suecica (Ts) from broodstock to pre-settlement, were studied. Lower larval growth (5.5m to 6.5m/d) was recorded in progeny continuously fed single S.marinoi or T.suecica, whereas good growth was achieved with single T.lutea (7.8m/d). Larvae, originated from broodstock receiving Sm or Ts, exhibited growth compensation when fed a bispecific balanced diet (TCg). This did not occur when broodstock and larvae were fed Cg or T, for which single or mixed diets led to similar larval growth. Furthermore, survival was high (>90%) regardless of... |

| The feeding ecology of the red knot has been widely studied across its wintering range. Red knots mainly select bivalves and gastropods, with differences between sites due to variation in prey availability. Shorebird’s diet is also influenced or controlled by the tidal regime. The aim of this paper is to demonstrate the adaptation of foraging red knots to the megatidal environment. The variation in their diet during tidal cycles was studied in the bay of Saint-Brieuc, a functional unit for this species. The method used combined macrofauna, distribution of foraging birds and diet data. Comparative spatial analyses of macrofauna and distribution of foraging red knots have shown that the bay's four benthic assemblages are exploited by birds. By analysing... |

| This study aimed at comparing toxic element (Hg, Cd) bioaccumulation in relation to age for bottlenose (Tursiops truncatus) and striped dolphins (Stenella coeruleoalba) from Mediterranean and Atlantic waters. Metal concentrations were also measured in selected prey to infer metal exposure through the diet. As expected, Mediterranean prey exhibited the highest Hg levels, probably as a consequence of the Hg enrichment of the Mediterranean Sea. Comparing the predators from each area and taking age into account, Mediterranean bottlenose dolphins displayed higher Hg levels than Atlantic dolphins (p = 0.032), whereas Mediterranean striped dolphins did not (p = 0.691). The consumption of Myctophid fish, which showed the highest Hg levels (105 +/- 80 ng g(-1)... |

| Seabass were fed for 4 months with diets where the lipid was provided as either canola oil (CO), palm oil ( PO) or fish oil (FO), to generate diversity in their tissue fatty acid (FA) composition and investigate how this influenced major traits of exercise performance, cardiac performance and respiratory metabolism. In particular, based upon previous observations, we investigated the hypothesis that enriching the fish tissues with oleic and linoleic acids (OA, 18:1n-9 and LA, 18:2n-6, respectively) from the CO and PO diets would improve maximum exercise and cardiac performance, and increase aerobic metabolic scope. This proved to be the case; exercise respirometry on bass fitted with cardiac flow probes revealed that those fed CO and PO diets had a... |

| Concentrations of polychlorinated biphenyls (PCBs) in blubber of female common dolphins and harbour porpoises from the Atlantic coast of Europe were frequently above the threshold at which effects on reproduction could be expected, in 40% and 47% of cases respectively. This rose to 74% for porpoises from the Southern North Sea. PCB concentrations were also high in southern North Sea fish. The average pregnancy rate recorded in porpoises (42%) in the study area was lower than in the western Atlantic but that in common dolphins (25%) was similar to that of the western Atlantic population. Porpoises that died from disease or parasitic infection had higher concentrations of persistent organic pollutants (POPs) than animals dying from other causes. Few of the... |

| Animals have been developing key associations with micro-organisms through evolutionary processes and ecological diversification. Hence, in some host clades, phylogenetic distance between hosts is correlated to dissimilarity in microbiomes, a pattern called phylosymbiosis. Teleost fishes, despite being the most diverse and ancient group of vertebrates, have received little attention from the microbiome perspective and our understanding of its determinants is currently limited. In this study, we assessed the gut microbiome of 12 co-occurring species of teleost representing a large breadth of ecological diversity and originating from a single family (i.e., the Sparidae). We tested how host evolutionary history, diet composition and morphological traits are... |

| Feeding preferences of Celtic Sea fishes were investigated using a database of stomach content records, collected between 1977 and 1994. The diet of cod Gadus morhua, hake Merluccius merluccius, megrim Lepidorhombus whiffiagonis, whiting Merlangius merlangus and saithe Pollachius virens changed markedly as the animals grew larger, and although large predators generally chose larger bodied prey, the variability of prey sizes consumed also increased. Large predators continued to select small, low value, benthic prey (e.g. Callionymus spp. and Trisopterus spp.) which were easier to catch, rather than larger, more energy lucrative pelagic prey (e.g. mackerel Scomber scombrus), even though these pelagic prey-fishes were nearly always available and were often... |

| Sesamin is a major lignan constituent of sesame seed and considered as a key factor in a number of beneficial effects on human health. Sesame leaves intake improve and increase epididymal spermatocytes reserve in adult male sprague dawley rat. The present study was aimed to investigate the effects of contain sesame seed on epididymis histologhical structure. Thirty adult male rats were divided into two groups of 15 rats each. The regimen group received diet containing 30% sesame seed, while the control group received diet along 12 weeks. The right epididymis were removed and minced into several pieces on a specimen bottle containing normal saline for some few minutes to allow the sperms to become motile and swim out and sperm parameters were analyzed. Left... |

| This study evaluated whether a high fat diet (HFC group) induces overweight, hepatic steatosis and plasma lipoproteins level alteration compared to standard chow diet (SC group). Female mice were submitted to each diet over 6 months. Body mass and food intake were evaluated weekly throughout the experiment. Total cholesterol, TG, LDL-c, HDL-c and VLDL-c were analyzed. Mice were sacrificed to remove liver, spleen, heart and intestine. The volume of the organs was determined according to the submersion method. Fixed livers were embedded in paraffin and stained with hematoxylin and eosin and Masson's trichrome. The analysis used a video microscope system and a test-system with 42 test-points. The volume density was estimated for hepatocytes, steatosis and... |

| The contents of soybean can modify the structure of the reproductive system, especially, when consumed for prolonged periods. In this study, we evaluated the effects of the consumption of transgenic soybean on rat penis morphology after prolonged use. Wistar rats (n = 30) were divided into three groups according to diet: Transgenic Soybean (TS) group, Organic Soybean (OS) group and Control (C) group. After 455 days of intake, the rats were sacrificed and the penises were excised and fixed in formalin for subsequent histological processing. The samples were stained with hematoxylin and eosin, Weigerts resorcin-fuchsin stain, and picrosirius red with polarization. The images were scanned for the histomorphometric analyses of the corpora cavernosa, corpus... |

| The present study was carried out to evaluate the effect of statins associated with physical exercise (PE) in liver cells in dyslipidemic rats through cariometry. The animals were divided into six groups: animals subjected to a hypercholesterolemic diet (HD), simvastatin, with (G1) and without (G2) physical exercise (PE); HD submitted (G3) or not (G4) to PE, and commercial food diet (F) with (G5) and without (G6) PE. Histological analysis of the liver was performed by staining the slides with hematoxylin and eosin. The cariometric study included measuring the major and minor diameters of the hepatocytes nuclei. The Shapiro-Wilk test was also performed. To determine the differences among the groups, the Kruskal-Wallis Test with Dunn's post-test were... |

| The present study aims at improving the characterization of the dietary status of four sigmodontine rodents (Graomys griseoflavus, Akodon molinae, Calomys musculinus and Eligmodontia typus) by quantifying the major food categories (leaves, stems, seeds, Prosopis flexuosa pods, and arthopods) with a modified microhistological technique. The use of this new technique enhances the likelihood of accurately identifying plant parts, such as stems, seeds and fruits that are usually underestimated. Results reveal that hard tissues, like seeds, are a major resource in the diets while other hard tissues, such as stems and P. flexuosa pods, appear for the first time in the diet of all four species of sigmodontine rodents. Rodent species display considerable trophic... |

| The chemical composition of salt licks and the diet of the mountain tapir (Tapirus pinchaque) were studied in the upper montane rain forests (2900-3700 m), in the Parque Regional Natural Ucumari and Parque Nacional Natural Los Nevados, Colombia. We collected water samples from the salt licks, 28 feces and voucher specimens of plants with tapir browsing sign. The chemical analysis of the water from salt licks showed higher concentrations of Na, N-NH4 y N-NO3when compared to the water of a nearby stream used as control. The nitrogen of the water at the salt lick is probably being fixed by Nostoc, a Cynobacteria associated with Gunneramanicata and G. magnifolia, two plants located in the upper part of the rocky cliff from where the water drains to the salt... |

| We evaluated the application of faecal analysis as a complementary approach to direct observation in the study of Callithrix jacchus feeding ecology. Our results indicate that animal foods may be more commonly consumed (based on faecal samples-FS; 61.48% of diet) than previously thought (e.g., only 22.83% based on observational data-OD). Whereas FS provide better data on animal prey, it was less effective than OD in identifying plant items. Six insect orders-including Dermaptera and two hymenopteran families, not previously recorded in marmoset diet-were identified through FS, which is thus shown to be useful in characterizing diet, especially in insectivorous primates. |

| We investigated the diet of gracile mouse opossum, Gracilinanus agilis (Burmeister, 1854), from the analysis of 144 fecal samples collected between November 2009 and October 2011 in an area of savanna riparian forest in the Brazilian Cerrado. Invertebrates were the most frequently consumed food items (96.5%) followed by fruits of pioneer species (29.8%) and flowers (6%). We also observed the presence of fragments of bird vertebrae and downs in samples from 2 adult males, this being the first record of predation on small vertebrates by G. agilis. The presence of fragments of birds in the feces of the gracile mouse opossum suggests that despite the small size of this species and its primarily insectivorous habits, small vertebrates may be included in its diet. |

| The nocturnal distribution and resource use by Ryukyu flying foxes was studied along 28 transects, covering five types of habitats, on Iriomote Island, Japan, from early June to late September, 2005. Bats were mostly encountered solitarily (66.8%) or in pairs (16.8%), with a mean linear density of 2.5 ± 0.6 bats/km of transect/night. Across the island, however, bat densities were distributed non-randomly among transect-nights, not correlated with transect length, and showed a slightly clumped distribution (variance/mean = 3.3). Outskirt trails contributed higher values to the relative importance of bat abundance, but the highest mean abundances occurred mostly at village sites on the west coast, which on average devoted only a quarter of their land area to... |

| Data are presented on the diet of Cory's Shearwater Calonectris diomedea borealis (Cory, 1881) resulting from stomach investigations based on 18 birds from Hierro (Canary Islands), 5 from Selvagem Grande (Selvagens or Salvage Islands), 2 from São Miguel and 1 from São Jorge (Azores), collected between 1977 and 1981. These data confirm the general idea that this shearwater feeds principally on fish and squid. The glandular stomachs of 9 birds from Hierro contained significant quantities of food, varying in wet weight from ca. 4-40 gm; in four cases more or less complete squids were present, all Ommastrephes bartrami (Le Sueur, 1821). In addition, the gizzards of all 26 birds, except one, contained fragments of squid beaks belonging to 12 species. Several of... |
