ABSTRACT We register for first time the occurrence of Epipompilus tucumanus Evans, 1967 in Brazil, and record the spider Ariadna boliviana Simon, 1907 as its host. The observations were made in the National Park of Chapada dos Guimarães, Mato Grosso, Brazil. The prey carriage mechanism is described for first time for this genus, and we provide a video showing this behavior. |

The objective of this study was to evaluate agronomic and molecular traits of the 'Italia Muscat' clone and compare it with the cv. 'Italia', providing information to support the cultivation of 'Italia Muscat' this cultivar in the São Francisco River Valley. Agronomic characteristics of both clones were evaluated for two seasons in 2004. The characteristics were phenology, bud break (%), bud fertility (%), yield (kg) mass of bunches (g), length and width of bunches (cm), mass of berries (g), length and diameter of berries (mm), TSS (ºBrix), ATT (% titratable acidity) and TSS/TTA. Molecular analysis of seven SSR markers were carried out. The clone 'Italia Muscat' showed larger berries, mass of bunches and better TSS/TA ratio than 'Italia'. The molecular... |

Some bat species seem to be lunar phobic, i.e., they avoid flying in bright areas or during bright periods of the night; however, the evidence is still controversial. We think that part of this controversy comes from pooling data on bat captures and moonlight intensity according to broad categories, such as moon phases, which conceal the high variability among nights. Therefore, we used detailed, long-term field data on three phyllostomid bat species, in order to test the hypothesis of lunar phobia at two different time scales: 1) among nights, by pooling data of different nights according to moon phases and testing for differences in the distribution of captures; and 2) within a night, by analyzing the relationship between capturability and moonlight... |

We studied the thermal ecology and thermoregulatory behavior of Coleodactylus natalensis Freire, 1999 in a remnant of a northern coastal patch of the Brazilian Atlantic Forest. Data were collected during four 20-day field excursions over the course of one year. We assessed the importance of substrate and air temperatures, in addition to time of exposure to sunlight, as relevant factors for the regulation of body temperature in this species. After each specimen was captured, body (Tb), substrate (Ts) and air (Ta) temperature were measured 10 cm above the ground, using a temperature sensor coupled to a fast response thermo-hygrometer. Ad libitum and focal animal methods were used to describe thermoregulatory behavior. The mean body temperature of C.... |

We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles. Herein, the bromeligenous behavior is reported for the first time in Hypsiboas Wagler, 1830. Although this reproductive behavior has been observed more than once here, we believe that it is not typical of Hypsiboas, being better characterized as an unusual reproductive mode for Hypsiboas, indicating the presence of plasticity in the reproductive modes of H. pardalis |

Musk deer farming has the potential to be an effective conservation tool for the protection of musk deer as well as the production of valuable musk. To be successful, this requires a thorough understanding of the behavior of captive musk deer in order to improve their reproductive success and management. Between August 2005 to January 2006, the behavior sampling of 19 male and 13 female captive alpine musk deer, Moschus sifanicus Büchner, 1891, was used to examine the durations of twelve behavioral characteristics during the pre-rut (August to October) and rut seasons (November to January). Both males and females exhibited some seasonal variation in behavior. Males rested and fed more during the pre-rut than the rut and spent more time walking, fighting,... |

This research presents novel data on tree marking by the giant anteater, a large Neotropical mammal threatened in the state of Paraná and other areas of Brazil, and nearly threatened worldwide. Field work was carried out in the municipality of Jaguariaíva, Paraná (Southern Brazil) with the goal of evaluating the pine marking behavior of the giant anteater and ascertaining whether wildfires interfere with it. Anteater marks were searched for on the trunks of pine trees in stands as well as pine trees dispersed throughout the landscape. For each pine tree, the following features were recorded: height, diameter breast height (DBH), height of first branch, presence/absence of scratch marks, geographical location, substrate, and matrix. The total number of... |

Adequate habituation of free-ranging subjects is essential for any field study, but is generally unsystematic. Here, attempts to habituate three titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) groups are described, and factors determining the effectiveness of the process are discussed. The "relentless pursuit" approach was aided by playback recordings of vocalizations but only one group was habituated adequately. Average contact in 13 encounters with group 1 was just over one minute, whereas in 32 encounters with group 2, it averaged 3,5 minutes (maximum = 22 minutes). Group 3 was more tolerant of observers, and was considered fully habituated by the seventh encounter. The factors determining this disparity remain unclear, although... |

Insect-food-plant associations have been shown to be influenced by the chemical, physical and nutritional characteristics of plants. We suggest that among insect larvae that use leaf material to build shelters, food-plant use may be constrained by differences in host leaf structure, illuminating a rarely investigated aspect of insect-plant interactions. To explore the potential effects of leaf structure on shelter building behavior in a Neotropical skipper butterfly, we investigated shelter building patterns on two congeneric food-plants that varied in leaf thickness. Shelter architecture varied significantly between hosts, with thicker leaves requiring longer cuts to construct shelters. The relationship between shelter building behavior and leaf structure... |

The objective of this study was to assess the effect of the inclusion of passionflower (Passiflora alata) in diets on performance, behavior, heterophil/lymphocyte ratio (H/L), corticosterone plasma levels (CPL) and immune response of quails. The study was carried out using 192 birds, distributed in randomized blocks with 4 diets (0, 125, 250 and 375 and 0, 250, 500 and 750 mg of passionflower/kg of feed for the rearing and laying period, respectively), 8 replicates and 6 birds per experimental unit. The rearing period began when birds were 28 days of age and it lasted for 15 days. In this phase, it was evaluated daily feed intake, daily weight gain, feed conversion, viability, tonic immobility time, intensity of injuries, behavior, heterophil/lymphocyte... |

ABSTRACT This study aimed to investigate how type of hoof injury and corrective trimming alter the behavior of dairy cows. Thirty-four lactating Holstein and Jersey cows were used. They were scored for lameness score on days –2 and 6, before and after trimming and treatment, respectively, using a numerical rating system, in which 1 = perfect gait and 5 = severely lame, and had their postural and ingestive behavior evaluated on days –1 and 6 before and after trimming and treatment, respectively. Locomotion score was analyzed using t-paired test and behavioral data were analyzed by univariate variance analysis with cows as the experimental units, according to a completely randomized design with repeated measurements. Cows with infectious hoof diseases spent... |

The complexity of the consumers' behavior has taken the food industry to a new level of dynamism. Therefore, understanding the factors that influence this behavior is decisive for the differentiation of products to niche markets and even to adjust the supply according to consumers' expectancy. This article proposes a conceptual model to identify the factors influencing beef consumption in Brazil. The methodological approach was characterized by a systematic review through a synthesis of research related directly to this topic. Therefore, 76 papers published during the 2000-2014 period, including official documents (statistics), full research papers, abstracts, proceedings, and reports, were selected. Four main factors were related to influences in consumer... |
