| Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence of a correlation between the morphology and physiology of the intestinal tract and chemical features of the natural diet. However, studies correlating the activity of digestive enzymes and the feeding habits at an evolutionary scale are scarce. We investigated the effect of dietary habits on the digestive physiological characteristics of eight species of passerine birds from Central Chile. The Order Passeriformes is a speciose group with a broad dietary spectrum that includes omnivorous, granivorous and insectivorous species. We... |

| The diet and diel feeding pattern of the skate Raja agassizii were investigated through analysis of stomach contents. A total of 280 stomachs were collected by a series of hauls during a daily cycle in three periods, 8-10 January 1987, 22-24 July and 2-4 December 1988, from the inner continental shelf of the coastal ecosystem of Ubatuba, São Paulo State, Brazil (25º35'S; 45º00'W). According to the results of the stomach fullness and of the number of fresh prey, it is suggested that this species presents continuity in the feeding activity during a day. The stomach contents were mainly composed of crustaceans. Nematodes, polychaetes and fishes also occurred. No changes were observed in dietary composition between day and night. |

| The crab-eating fox, Cerdocyon thous (Linnaeus, 1766), is a small canid with twilight and nocturnal habits from savannas and forests of South America. In this study, we seasonally determined and quantified the diet of C. thous in Lami Biological Reserve, a conservation unit with 179.78ha situated in a suburban area in the municipality of Porto Alegre, southern Brazil. During the year 2000, we collected 80 fecal samples - 20 for each season - in two or three week sampling intervals, along trails inside the Reserve. Samples were dried in an oven for 24h at 60ºC, immersed in 70% alcohol, and prey items were identified using a stereomicroscope. The diet of the crab-eating fox was essentially carnivorous (87.62% composed by vertebrates), with seasonal variation... |

| This study identifies the food habits of the margay, Leopardus wiedii (Schinz, 1821), and the jaguarundi, Puma yagouaroundi (É. Geoffroy Saint-Hilare, 1803), in the Vale do Rio Doce Natural Reserve and in the Sooretama Biological Reserve, Espírito Santo, Brazil. We determined the diet of both species by the analysis of scats. Fecal samples were collected from April 1995 to September 2000 and identified based on the presence of hairs that were ingested during self-grooming. Scats were oven-dried and washed on a sieve, and the screened material was identified using a reference collection. Of the 59 fecal samples examined, 30 were confirmed to be from the margay and nine of them from the jaguarundi. Mammals were the most consumed items in the diet of the... |

| The dietary compositions of two sit-and-wait lizard species, Hemidactylus mabouia and Phyllopezus pollicaris, which co-occur over rocky substrate and vertical rock walls in a perianthropic area of western Brazil, were described. Both species showed a generalist feeding pattern, feeding mainly on insects. The most frequent prey items in the diet of P. pollicaris were Coleoptera, Araneae and Homoptera whereas the most important were Coleoptera and Homoptera, respectively. For H. mabouia the most frequent prey items were Araneae followed by Coleopterae and Hemiptera, whereas the most important items were H. mabouia followed by Formicidae and Hemiptera. Our identification into broader prey-types categories (i.e., order or family-level) suggests that some... |

| We studied the natural diet of two didelphid marsupial species, Didelphis aurita and Philander frenatus, at a rural area on southeastern Brazil, through fecal sample analysis. Data analysis included intraspecific comparisons (age, gender, and climatic seasons) and interespecific comparisons. Frequencies of food items were compared with other studies to analyze diet differences in a spatial scale. Invertebrates were the most frequent food category found in samples of both species, followed by fruits and vertebrates. There were no differences in the consumption of invertebrates, vertebrates and fruits between sexes in the two species, but both consumed more fruits in more humid months. Juveniles of P. frenatus consumed less vertebrates than adults or... |

| Abstract We describe here the diet of the microhylid frog Chiasmocleis leucosticta based on the stomach contents of 72 individuals (47 males and 25 females) collected in pitfall traps at the Reserva Florestal de Morro Grande, state of São Paulo, southeastern Brazil. We identified 1,981 food items distributed in 13 prey categories of arthropods, mainly ants, mites and collembolans. Formicidae was the most abundant and frequent prey category, including 16 genera from seven subfamilies, and data on ant availability in the habitat suggest that C. leucosticta selects ants actively. The second main prey category was Acari, predominantly represented by mites of the suborder Oribatida. This is the first work identifying mites to the family level in the diet of a... |

| Immigration has become a new phenomenon in Spanish society during the last years. In 2007, immigrants represented around 10% of total population, with 35% coming from Latin-American countries. When immigrants arrive, they bring their own values and cultural symbols, which, essentially, are different from those of the indigenous population. As time goes through, two alternative processes are observed: 1) a gradual switch towards the Host Society values; or 2) a maintenance of their ethnical identity. Focussing in the Latin-American immigrants in Barcelona, the objective of this paper is twofold: 1) to measure their degree of ethnical identity; and 2) to analyse the relationship between food habits and their ethnical identity. Food habits refer here to the... |

| The diet of the arboreal lizard E. bilineatus was assessed based on analysis of gut contents of specimens collected in the remnants of the Atlantic rainforest in Espírito Santo State, south-eastern Brazil. Stomachs of the lizards examined (SVL = 57.0-85.0 mm) contained nine arthropod orders. E. bilineatus utilizes a broad range of arthopodan prey type and sizes, and can be considered an arthropod generalist, which uses a sit-and-wait foraging strategy. Orthoptera represented the most important food item, followed by Dictyoptera and Hymenoptera. Hemiptera, Homoptera, Lepidoptera (larvae), Coleoptera, Araneae, and Diplopoda constituted the remainder of food items. The presence of Diplopoda, which are not generally found on tree trunks, provides particularly... |

| The diel of the giant armadillo - Priodontes maximus (Kerr,1792) - was studied in the field at Fazenda São Miguel, Unaí, Minas Gerais, Brazil, through 82 samples collected at foraging excavations and 25 fecal samples. In both types of sample the most common item was insects (Isoptera e Hymenoptera) and, in less quantity, plant fragments and orhers invertebrates (Aranae, Blattaria, Coleoptera, Diplopoda, Scorpiones). These data suggest the giant armadillo is a specialist on insects with an opportunistic foraging strategy. |

| La identificación precisa de heces de carnívoros silvestres es importante para describir sus hábitos alimenticios, sobre todo en aquellas especies elusivas o en riesgo. Sin embargo Identificar las heces de especies de carnívoros simpátricos no es una tarea sencilla. Por ello, las técnicas moleculares, son herramientas que brindan mayor precisión en la identificación de heces. El análisis de hábitos alimenticios aporta información valiosa para entender la estructura poblacional de los depredadores y sus presas, así como su importancia ecológica para generar estrategias de manejo y conservación de carnívoros y sus presas. Los objetivos de este estudio fueron identificar las heces de carnívoros extrayendo ADN mitocondrial de estas y amplificando un fragmento... |

| This study aimed at analyzing the influence of different levels of environmental integrity of streams of the Ivinhema river basin (Mato Grosso do Sul State, Brazil) on the diet of A. altiparanae. Samplings were performed from July 2001 to November 2011 at 101 sites, using sieves, seining and gill nets, and electrofishing. Streams were classified into three levels of environmental integrity. We analyzed 664 stomachs with the methods of frequency of occurrence and volumetric analysis index, combined in the Importance Index (AI). The species was omnivorous, with predominance of allochthonous resources. At the least impacted sites, the most representative resource was allochthonous plant material; and in the altered sites in the rainy period the most consumed... |

| Sixteen opportunistic field observations of eight species of Brazilian raptors (Falconiformes and Strigiformes) are reported here as a contribution to the knowledge of the natural history of these poorly studied birds in Brazil. The observations are related to the food habits (Buteo albicaudatus, Herpetotheres cachinnans, Milvago chimachima, Falco femoralis), reproduction (Asio stygius, Megascops choliba), mobbing behaviour elicited in other birds (Geranospiza caerulescens, H. cachinnans, F. femoralis, A. stygius, Athene cunicularia) and a rare case of leucism in owls (A. cunicularia). |

| Overweight is a worldwide growing epidemic. The Netherlands is among the countries with the highest prevalence for overweight, together with the USA, UK, and Germany. This paper investigates differences in overweight between native Dutch and three immigrant groups in the Netherlands, and the effects of food habits and socioeconomic status on overweight. The results show that all immigrant groups have a higher prevalence for overweight than the Dutch, apart from Moroccans. Males are overweight more frequently than females. Takeaway food, eating out, and fresh vegetables decrease BMI, while convenience food, ready-to-eat meals, and delivery food (in some cases) increase BMI. In all groups, BMI increases with age. For Surinamese/Antilleans and Turks BMI... |
