First host record of Epipompilus (Hymenoptera: Pompilidae) from Brazil and discussion of prey carriage mechanism 92
Trad,Bhrenno M.; Silvestre,Rogerio; Auko,Tiago H.; Lopez,Vinicius M.; Santos,Eduardo F. dos.
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.

Agronomic and molecular traits of the 'Italia Muscat' clone in Sao Francisco River Valley 94
Leão,Patrícia Coelho de Souza; Brandão,Elieth Oliveira; Gonçalves,Nadja Pollyanna da Silva.
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...

The use of pelvic fins for benthic locomotion during foraging behavior in Potamotrygon motoro (Chondrichthyes: Potamotrygonidae) 103
Shibuya,Akemi; Carvalho,Marcelo R. de; Zuanon,Jansen; Tanaka,Sho.
Synchronized bipedal movements of the pelvic fins provide propulsion (punting) during displacement on the substrate in batoids with benthic locomotion. In skates (Rajidae) this mechanism is mainly generated by the crural cartilages. Although lacking these anatomical structures, some stingray species show modifications of their pelvic fins to aid in benthic locomotion. This study describes the use of the pelvic fins for locomotory performance and body re-orientation in the freshwater stingray Potamotrygon motoro (Müller & Henle, 1841) during foraging. Pelvic fin movements of juvenile individuals of P. motoro were recorded in ventral view by a high-speed camera at 250-500 fields/s-1. Potamotrygon motoro presented synchronous, alternating and unilateral...

Behavioral responses of humpback whales, Megaptera novaeangliae (Cetacea: Balaenopteridae), to satellite transmitter deployment procedures 103
Alves,Luiz Cláudio P. de S.; Moreira,Sérgio; Simões-Lopes,Paulo C.; Andriolo,Artur.
Tagging whales with implantable satellite transmitters creates the possibility of disturbing the animals. Between 2003 and 2005, behavioral observations of humpback whales during tag deployment operations were conducted off the coast of Brazil from the flying bridge of a speedboat. The speed achieved by each whale during pursuit was registered by GPS receivers onboard two inflatable zodiac boats. Respiratory frequencies were significantly lower (n = 15, p < 0.05) before (mean = 0.89 ± 0.06 blows/min) compared with after (1.39 ± 0.15) tagging. The same effect was observed for the speed of each animal (mean = 10.96 ± 0.44 km/h and 12.54 ± 0.57 km/h; n = 13, p < 0.05). Both variables were positively correlated with the duration of the pursuit (n = 21, r...

Effects of moonlight on the capturability of frugivorous phyllostomid bats (Chiroptera: Phyllostomidae) at different time scales 103
Mello,Marco A. R.; Kalko,Elisabeth K. V.; Silva,Wesley R..
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...

The biology and functional morphology of Macoma biota (Bivalvia: Tellinidae: Macominae) 103
Piffer,Pedro Ribeiro; Arruda,Eliane Pintor de; Passos,Flávio Dias.
Macoma biota Arruda &amp; Domaneschi, 2005, is a recently described species known only from the intertidal zone of Praia da Cidade, Caraguatatuba Bay, in the state of São Paulo, southeastern Brazil. The main purpose of the present paper is to describe the biology of M. biota, beginning with a detailed analysis of its anatomy and functional morphology and how these attributes are correlated with its habitat and life history. The morphology of the organs in the pallial cavity and their sorting devices indicate that this species has efficient mechanisms to process large amounts of particles that enter this cavity via the inhalant current. M. biota can rapidly select the material suitable for ingestion and direct the undesired excess to the rejection...

Thermal ecology and thermoregulatory behavior of Coleodactylus natalensis (Squamata: Sphaerodactylidae), in a fragment of the Atlantic forest of northeastern, Brazil 103
Sousa,Pablo A. G. de; Freire,Eliza M. X..
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....

An unusual reproductive mode in Hypsiboas (Anura: Hylidae) 103
Moura,Mário Ribeiro de; Motta,Ana Paula; Feio,Renato Neves.
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

Seasonal variation in the behavior of captive alpine musk deer, Moschus sifanicus, in Xinglongshan Musk Deer Farm, of China 103
Xiaofeng,Luan; Changjie,Zhao; Cenyi,Hui; Xiuxiang,Meng.
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,...

Factors affecting escape distance in birds 103
Piratelli,Augusto J.; Favoretto,Gabriela R.; Maximiano,Marina F. de Almeida.
ABSTRACT The flight initiation distance has been used either to understand the cost-benefit trade-offs related to the risk of predation or as an important tool for wildlife managers. Although this variable is well-discussed for temperate regions, it is still poorly known in the Neotropics. Here we analyze the escape behavior of birds from southeastern Brazil, comparing an urban to a non-urban area. We tested for the influence of sites (urban vs. non-urban area), approaching (by one vs. two people), daytime (morning vs. afternoon), seasons (breeding vs. non-breeding) and body mass on the determination of the initial (FID) and final (FFD) flight distances across different bird species. We predict that FID will be greater in rural areas and under a greater...

Marking behavior of the giant anteater Myrmecophaga tridactyla (Mammalia: Myrmecophagidae) in Southern Brazil 103
Braga,Fernanda G.; Santos,Raphael E. F.; Batista,Antonio C..
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...

Responses of wild titi monkeys, Callicebus coimbrai (Primates: Platyrrhini: Pitheciidae), to the habituation process 103
Souza-Alves,João Pedro; Ferrari,Stephen F..
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 &amp; 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...

Architectural changes in larval leaf shelters of Noctuana haematospila (Lepidoptera: Hesperiidae) between host plant species with different leaf thicknesses 103
Greeney,Harold F.; Walla,Thomas R.; Lynch,Ryan L..
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...

Daily activity patterns of Saanen goats in the semi-arid northeast of Brazil 96
Paulo,Jória Leilane de Albuquerque; Lopes,Fívia de Araújo.
The objective of the study was to characterize the daily feeding activity patterns of Saanen goats (Capra hircus) as a function of changes in climatic variables. The investigation was conducted in the municipality of Cruzeta, 300 km from the city of Natal, Brazil. Seventeen free-ranging female Saanen goats were selected for observation, wherein they were kept on a pasture with native vegetation and also received concentrated feed in a trough. Observational records of behavior on pasture were collected using focal animal and scan sampling for these specific behaviors: ruminating while standing or lying down, standing idly or lying down, walking, grazing and eating. Eating was the predominant activity observed. The frequency of some behaviors changed in...

Effects of type of lesion and trimming on short-term behavior of grazing dairy cows 96
Cruz,Eduardo Augusto da; Fischer,Vivian; Passos,Lorena Teixeira; Porciuncula,Gabriela Caillava da; Stumpf,Marcelo Tempel; Werncke,Daíse; Santos,Carolina da Silva dos.
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...

Influence of temperament-related genes on live weight traits of Charolais cows 96
Garza-Brenner,Estela; Sifuentes-Rincón,Ana María; Rodríguez-Almeida,Felipe Alonso; Randel,Ronald D.; Parra-Bracamonte,Gaspar Manuel; Arellano-Vera,Williams.
Abstract We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young cows were used to determine Pearson's correlations between birth (BW), weaning (WW), and yearling live (YW) weight and temperament traits (measured as exit velocity [EV] and temperament score [TS]). For association analysis, selective genotyping of a group of 80 cows identified as the most docile and temperamental were genotyped with a 151-SNP (single-nucleotide polymorphisms) panel of molecular markers previously associated with temperament. Significant Pearson's correlations between birth weight and weaning weight and the two...

Using an observer rating method to assess the effects of rotational stocking method on beef cattle temperament over time 96
Góis,Karen Camille Rocha; Ceballos,Maria Camila; Sant'Anna,Aline Cristina; Costa,Mateus José Rodrigues Paranhos da.
ABSTRACT The objectives of this study were to propose behavioral-based definitions for the adjectives used in an observer rating method, and to use this approach to characterize temperament over time in cattle kept under rotational stocking method. We also analyzed the feasibility of the rating method under commercial cattle farming conditions. We evaluated the temperament evolution of 1,979 pure and crossbred Nellore young bulls over time on three commercial farms located in Northeastern Pará State, Brazil. All animals were kept under a rotational stocking method. The observer rating method included 14 behaviorally predefined adjectives for which we defined the minimum and maximum scores. The first factor was considered a qualitative temperament index...

Conceptual model to identify factors with influence in Brazilian beef consumption 96
Brandão,Fernanda Scharnberg; Barcellos,Júlio Otávio Jardim; Waquil,Paulo Dabdab; Oliveira,Tamara Esteves de; Gianezini,Miguelangelo; Dias,Eduardo Antunes.
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...
