| Knowledge of information relative to the digestibility, intake and botanical and morphological composition of the diet is important in nutritional studies, since it provides the basis for understanding aspects related to the ingestive behavior and selectivity of animals. N-alkanes have been used successfully as markers in studies with many species of animals, particularly domesticated ruminants, most of the times as replacements for conventional markers as chromium oxide for example. However, for wild ruminants and non-ruminant animals information on this technique is still scarce and, as a consequence, its potential for use unknown. This review reports the use of this technique in studies of feed digestibility, intake and diet composition with wild... |

| The lionfish (Pterois volitans) has established in the Colombian Caribbean coast. Its presence was reported for the first time in continental Colombia in 2009, but its abundance has increased significantly by the end of 2009 and 2010, being now common to find it in the entire Colombian Caribbean. The present study evaluates the diet components of the lionfish in Santa Marta and Tayrona National Park. Five teleost families (Apogonidae, Gobiidae, Serranidae, Clupeidae, and Pomacentridae) and some crustaceans were identified as components of the diet of the lionfish. Some of these organisms belong to families of ecological and economic importance, which can have impacts on populations of local fish as has happened in other latitudes. Consequently, this... |

| This study reveals the food composition of pelagic fishes living in the southwestern Atlantic Ocean. As such more common pelagic species are considered to be top predators, the study proposes to know what constitutes their main food. Fish are not commonly found within their stomach contents, but instead, cephalopods are their most common food. As can be observed, Teuthida cephalopods compose their principal diet. The stomach contents of specimens of Xiphias gladius, Thunnus albacares, T. obesus, T. alalunga, Isurus oxyrinchus and Alopias superciliosus caught during July 2007 to June 2009 by using tuna longliners were studied. Teuthida cephalopods constitute the main food item for the three tuna species, while X. gladius feeds mainly on Ommastrephidae... |

| The effectiveness of a seed disperser depends, among various factors still poorly understood for many Neotropical primates, on the amount of time seeds are retained within its digestive tract. This study tested the effects of sex, seed size and dietary fiber content on seed retention time in the digestive tract of black howler monkeys (Alouatta caraya). Experiments were performed using six captive individuals (three of each sex), six seed species distributed in three size classes (small, medium, and large), and three percentages of leaves in the diet (15, 30 and 60% of total food ingested). Retention times were recorded for 1767 recovered seeds, corresponding to 55% of the total ingested. More than 98% of these seeds were undamaged, suggesting the... |

| 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... |

| The aquatic grasshopper Cornops aquaticum (Bruner) is native to South America and inhabits lowlands from southern Mexico to Central Argentina and Uruguay. This grasshopper is host-specific to aquatic plants of the genera Eichhornia and Pontederia. The objectives of this study were to analyze the feeding patterns of the aquatic grasshopper C. aquaticum in relationship to development stages and sex and to determine the food consumption rate in their host plant, Eichhornia crassipes. Samples were collected from April 2006 to May 2007 in different floodplain lakes of the Middle Parana River. The average consumption was greater in the females (0.127 g food/day ± 0.051) than in the males (0.060 g food/day ± 0.025). The feces of 361 nymphs and adults of this... |

| The food habits and seed dispersal promoted by Thrichomys apereoides (Rodentia, Echimyidae) were investigated in a Cerrado reserve in southeastern Brazil. Diet was determined by faecal analysis and seed dispersal was tested through seed germination experiments. As a result, 68 scats of T. apereoides were collected and in mean 76.5% contained arthropods, hymenoptera being the most frequent food item. Moderate to high germination rates obtained showed that, despite the efficiency of the rodent's feeding apparatus, small sized seeds of pioneer plants passed undamaged through the guts and remained viable. The high consumption of seeds belonging to pioneer plants (Clidemia urceolata and Miconia holosericea) emphasizes the importance of T. apereoides related to... |

| The spider Latrodectus mirabilis (Holmberg, 1876) is commonly found in cereals crops of central Argentina. We studied its diet composition at the field and capture rate on leaf-cutting ants based on laboratory experiments. This study comprises the first approach that documents the diet of L. mirabilis in wheat and oat fields of central Argentina. We identified 1,004 prey items collected from its webs during the last phenological stages of both cereal crops. The prey composition was variable but the spiders prey mainly on ants (Formicidae, Hymenoptera), who represented more than 86% of the total. Meanwhile, in the capture rate experiences we registered a high proportion of ants captured by spiders at the beginning of experiences, capturing the half of the... |

| The world has seen a remarkable shift from a period when diets, activity patterns and body composition were characterized by the period termed the receding famine pattern to one dominated by nutrition-related non-communicable diseases (NR-NCDs). This presentation first examines the speed of these changes, summarizes dietary changes, and provides some sense of the way the burden of obesity is shifting from the rich to the poor not only in urban but also rural areas throughout the world. The focus is on the lower- and middle- income countries of Asia, Africa, the Middle East, and Latin America but some examples will come from the United States, Australia, and the UK. After showing that changes are occurring at great speed and at earlier stages of countries'... |
