A closer look at the main actors of Neotropical floodplain food webs: functional classification and niche overlap of dominant benthic invertebrates in a floodplain lake of Paraná River Iheringia, Sér. Zool.
Saigo,Miguel; Marchese,Mercedes; Wantzen,Karl Matthias.
ABSTRACT Functional classification of animals is necessary to enhance the predictive power of food web models. However, while there is a large database for functional classification of benthic invertebrates (Functional Feeding Groups, FFG) in the temperate zone, the attribution of individual species of riverine invertebrates is still in its infancies in the Neotropical Region. Different authors hypothesized that diet breadth was larger in the Tropics, however detailed analysis are scarce. In the present study we aimed at classifying dominant benthic taxa of the Middle Paraná River floodplain (Argentina) into trophic guilds by diet and niche overlap analyses. We sampled twelve taxa of benthic invertebrates from a floodplain lake during low water season and...

A structural model of wealth, obesity and health in the UK AgEcon
Mazzocchi, Mario; Traill, W. Bruce.
Based on a household health production framework, this paper exploits the combination of socioeconomic, health and nutrition information from the UK National Diet and Nutrition Survey to analyze the endogenous relationship among wealth, nutrition, weight and the final health outcomes. Results show that higher wealth determines lower weight and better health as expected, but through a better diet rather than extra exercise or lower calorie consumption.

A study of stomach contents of Cory's shearwater, Calonectris diomedea borealis (Cory, 1881) (Aves: Procellariidae), from the Macaronesian Islands Naturalis
Hartog, J.C. den; Clarke, M.R..
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...

A study on the short-term effect of cafeteria diet and pioglitazone on insulin resistance and serum levels of adiponectin and ghrelin BJMBR
Colombo,G.; Bazzo,M.L.; Nogueira,C.L.; Colombo,M.D.H.P.; Schiavon,L.L.; d’Acampora,A.J..
The interaction between ghrelin and adiponectin is still controversial. We investigated the effect of cafeteria diet and pioglitazone on body weight, insulin resistance, and adiponectin/ghrelin levels in an experimental study on male Wistar rats. The animals were divided into four groups of 6 rats each, and received balanced chow with saline (CHOW-O) or pioglitazone (CHOW-P), or a cafeteria diet with saline (CAFE-O) or pioglitazone (CAFE-P). The chow/cafeteria diets were administered for 35 days, and saline/pioglitazone (10 mg·kg body weight-1·day-1) was added in the last 14 days prior to euthanasia. CAFE-O animals had a higher mean final weight (372.5 ± 21.01 g) than CHOW-O (317.66 ± 25.11 g, P = 0.017) and CHOW-P (322.66 ± 28.42 g, P = 0.035) animals....

A weight loss protocol and owners participation in the treatment of canine obesity Ciência Rural
Carciofi,Aulus Cavalieri; Gonçalves,Karina Nogueira Venturelli; Vasconcellos,Ricardo Souza; Bazolli,Rodrigo Sousa; Brunetto,Márcio Antonio; Prada,Flávio.
The success of a weight loss program for pets depends on the owners collaboration. Their compliance is fundamental in establishing the correct food management. The objective of this study was to compare the effectiveness of a weight loss program in two groups of dogs, one maintained under experimental conditions and the other with their owners. The same hypocaloric food was used to feed all animals, the amount being restricted to 60% of the estimated maintenance energy requirement for a 15% reduction of the present body weight of the dog. The animals were followed during 90 days. A standard questionnaire was used to study the owners' perception of obesity and its treatment. The protocol and the diet were found to be effective. The control dogs had an...

Activity, habitat utilization, feeding behaviour, and diet of the sand moray Gymnothorax ocellatus (Anguilliformes, Muraenidae) in the south western Atlantic Biota Neotropica
Santos,Flávia Borges; Castro,Ricardo M. C..
Activity, habitat utilization, feeding behaviour, and diet of the sand moray Gymnothorax ocellatus (Anguilliformes, Muraenidae) in the South western Atlantic. The sand moray Gymnothorax ocellatus is a nocturnal predator from the western South Atlantic that actively forages on the bottom, preying mostly on crustaceans (mainly shrimps and crabs) and ray-finned fishes, which are located primarily by the sense of smell. The individuals stay stationary during the day, almost always being hidden in individual tunnels dug by animals other than the morays in the muddy sand bottom.

Aging and food source effects on mandibular stylets teeth wear of phytophagous stink bug (Heteroptera: Pentatomidae) Neotropical Entomology
Depieri,Rogério A; Siqueira,Fábio; Panizzi,Antônio R.
Studies were conducted to test the effect of age and food sources on wear of the mandibular teeth of the phytophagous pentatomid, Euschistus heros (F.). The total length (µm) of the area bearing the mandibular teeth, the length of the 1st tooth, and the height of the 2nd tooth for teneral (< 1 day-old) adults were significantly greater than that of adults fed on natural [green bean, Phaseolus vulgaris pods, raw shelled peanuts, Arachis hypogaea, and mature soybean, Glycine max seeds] for 30 or 60 days. Adults fed on artificial dry diet showed, in general, similar results to those of teneral adults. Force (Newtons) required penetrating the natural foods was significantly greater than that required penetrating the artificial diet. The greater hardness of...

Alimentação de Bairdiella ronchus (Cuvier) (Perciformes, Sciaenidae) na Baía de Guaratuba, Paraná, Brasil Zoologia
Vendel,Ana Lúcia; Chaves,Paulo de Tarso da Cunha.
Seasonal variation of food items of Bairdiella ronchus (Cuvier, 1830) classified by size was analysed based on monthly samples between september/1993 and september/1996 at the Guaratuba Bay, Southern Brazil. The stomach contents of a hundred eighty-two fishes were analysed by the Occunence Frequency Method and Point Count for a Lot Method. The individuais were divided in two groups, smaller and longer than 140mm, and a comparative study of digestive tract and branchial are was performed for these groups. For fishes smaller than 140mm the following sequence of items was obtained matching both methods by using the Preponderance índices: decapods (subdivided in Brachyura, Caridea and Penaeidea), polychaets, isopods, fishes, unidentified material, copepods,...

Alimentação de Oligosarcus longirostris Menezes &amp; Gèry (Osteichthyes, acestrorhynchinae) do Reservatório de Salto Segredo, Paraná, Brasil Zoologia
Gealh,Ana Maria; Hahn,Norma Segatti.
In the feeding study of O. longirostris Menezes &amp; Gèry, 1983, 211 stomachs from fish caught between March 1993 and February 1994 were analysed. Diet composition was analysed by the index of relative importance which deals with the numerical and gravimetric occurrence frequency. Results indicated that the species is piscivorous and its preferential food consisted oíAslyanax sp. 2. It was also found that Astyanax sp. 3 became an important food item, depending on the site of capture and its availability. Availability of prey seems to have a strong influence on the diet of O. longirostris. This same tendency has been observed during the different seasons of the year. Ontogenetic changes have also been found in the basic diet.

Alimentação de um filhote de bem-te-vi, Pitangus sulphuratus (Linnaeus) (Passeriformes, Tyrannidae), em ambiente urbano Zoologia
Argel-de-Oliveira,Maria Martha; Curi,Nancy A; Passerini,Tatiana.
The observation of parents feeding a captive fledgling of Great Kiskadee revealed that visitation is more frequent in the first hour after sunrising, with lesscr peaks along the day. The diet supplied consisted mainly of insects (Hymenoptera, Lepidoptera, Coleoptera, Diptera), along with other items as human-made materiais (food scraps, pellets of animal food), lizards (Hemidactylus mabouia), non-identified fruit pulp, gastropods and arachnids (Opiliones). The ability that P. sulphuratus has for identifying food items absent froni more natural habitats and for exploiting resources of unpredictablc spatial and temporal distributions confers the species a dietary flexibility that probably contributes to its efficiency in colonizing urban habitats.

Alimentação em machos e fêmeas do pirá-brasília, Simpsonichthys boitonei Carvalho (Cyprinodontiformes, Rivulidae) Zoologia
Shibatta,Oscar Akio; Rocha,Antônio José Andrade.
Simpsonichthys boitonei Carvalho, 1959 has an evident sexual dimorphism, easily observed in the color pattern and body proportions. In order to know the differences in the diet between males and females, the stomach contents of 28 individuals was examined. The Sorensen's index of similarity showed 90.9% of food items in common between sex. The main food in this species is Cladocera as evidenced in terms of average number, abundance and frequency of occurrence. The presence of vegetable is evidence of a high flexibility of this species in relation to the feeding behavior. Maybe the differences in the social behavior between sex are important in the total amount of ingested food.

Apparent digestibility coefficients of selected protein ingredients for pirarucu Arapaima gigas (Teleostei: Osteoglossidae). Repositório Alice
RODRIGUES, A. P. O.; MORO, G. V.; SANTOS, V. R. V. dos; FREITAS, L. E. L. de; FRACALOSSI, D. M..
Apparent digestibility coefficients (ADCs) of nine protein ingredients were determined for pirarucu Arapaima gigas, a Neotropical fish species with great aquaculture potential in the Amazon. ADCs of crude protein, energy and dry matter were determined by feces sedimentation in cylindrical-conical tanks. Experimental diets were composed of 795 g kg-1 of the reference diet, 5 g kg-1 of chromic oxide and 200 g kg-1 of the following test ingredients: fish by-product meal, salmon by-product meal, poultry by-product meal, hydrolyzed feather meal, meat and bone meal, blood meal, soybean meal, corn gluten meal and corn gluten feed. Blood meal, meat and bone meal and corn gluten feed resulted in low ADCs for pirarucu, whereas corn gluten meal, poultry by-product...

Are levels of digestive enzyme activity related to the natural diet in passerine birds? Biol. Res.
Ramírez-Otárola,Natalia; Sabat,Pablo.
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...
