| AbstractThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri (Syagrus coronata (Mart.) Becc.). Titratable acidity was analyzed by volumetric neutralization, soluble solids by refractometry, proteins by the micro-Kjeldahl method, lipids by gravimetry using soxhlet, dietary fiber by non-enzymatic gravimetry, carotenoids and vitamin C by HPLC-DAD, vitamin E by HPLC-fluorescence, and minerals by ICP-AES. Pulp were a source of Zn (0.95 mg 100–1), a good... |

| ABSTRACT This study was carried out in a section of the middle course of the Teles Pires River, a clear water river that drains ancient and highly eroded geological formations, and where five hydropower plants are planned or in construction. In this study we tested the hypothesis that local fish fauna is mainly sustained by autochthonous food resources, with modest changes in the trophic structure of fish assemblages along the hydrometric cycle. Sampling was performed every three months between July 2008 and May 2009 at seven sites distributed along a 50-km section of the river. Piscivores was the most representative group in terms of biomass, abundance and species richness, followed by herbivores, insectivores and omnivores. The trophic structure did not... |

| Ghana with population of 18.4 million (2000), is located on Latitude 4,44’N 11,11’N and longitude 3,11’W, 1,11’E. The country has a total land area of 23,853,900 HA and agricultural land area of 13,628,179 HA. The agricultural sector is the dominant sector in the Ghanaian economy. The total area under cultivation and irrigation are 5,808,600HA and 11,000 HA respectively. Agriculture is predominantly on a small holder basis although there are few large farms and plantations particular for oil palm, coconut, rubber and to a lesser extent rice, maize, and pineapple. Main crops cultivated are the cereals; maize, rice, millet, sorghum and the starchy crops of cassava, yam, cocoyam and plantain. Fruits and vegetables are increasingly being produced and exported... |

| ABSTRACT During flight, hummingbirds achieve the maximum aerobic metabolism rates within vertebrates. To meet such demands, these birds have to take in as much energy as possible, using strategies such as selecting the best food resources and adopting behaviors that allow the greatest energy gains. We tested whether hummingbirds choose sources that have higher sugar concentrations, and investigated their behaviors near and at food resources. The study was conducted at Atlantic forest remnant in Brazil, between June and December 2012. Four patches were provided with artificial feeders, containing sucrose solutions at concentrations of 5%, 15%, 25% and 35% weight/volume. Hummingbird behaviors were recorded using the ad libitum method with continuous... |

| The objective of this study was to evaluate the seasonal and daily variation in sexual behavior of Morada Nova breeders raised in the Brazilian semi-arid region. The data were collected from four rams and 114 ewes of the Morada Nova breed - 55 females in the dry season and another 59 in the rainy season. Observations were performed in the dry and rainy seasons, divided into four times of the day: morning (05:01 h to 11.00 h), afternoon (11.01 h to 17.00 h), evening (17.01 h to 23:00 h), and dawn (23:01 h to 05.00 h). Sexual behavior was assessed for a period of 24 h/day, in a breeding season. One ram was used each three days. The behavioral patterns of the rams in view of females were observed during the recognition (sniffing the female urine, bouts of... |

| This study was carried out in the region of Londrina, Paraná, Brazil in three different areas: a primary forest, a disturbed primary forest and an open area. Within 207 hours of capture, 990 individuals were collected, 939 of them being fruit-eating bats. Carollia perspicillata (Linnaeus, 1758), Sturnira lilium (Geoffroy, 1810), Platyrrhinus lineatus (Geoffroy, 1810) and Artibeus lituratus (Olfers, 1818) were the four most collected species in a total of 899 individuals. A. lituratus was found in greater number in all the areas, showing significant variation in relation to the size of the forests. The partition of food resources among the four most collected species was known through the analysis of their feces. The coexixtence of these species can be... |
