Apis mellifera discrimination between flowers of commercial types of melon and implications to crop pollination Rev. Ciênc. Agron.
Fernandes,Nayanny de Sousa; Pinto,Gercy Soares; Zocolo,Guilherme Julião; Aragão,Fernando Antonio Souza de; Freitas,Breno Magalhães.
ABSTRACT We investigated the foraging pattern of A. mellifera in five commercial types of melon (Yellow, Cantaloupe, Charentais, Galia and Piel de Sapo) grown side by side. We also observed if this bee species can discriminate between flowers of the five melon types and if it shows preference for flowers of any of them. Results showed that the bees visit flowers of all types of melon throughout the day collecting pollen and nectar in similar foraging patterns. However, they visited significantly more flowers of the Cantaloupe type followed by the types Piel de Sapo and Yellow, while the melons type Galia and Charentais were the least visited by the bees. This behavior has implications for the use of A. mellifera for melon pollination, requiring that the...

Body condition influences ontogeny of foraging behavior in juvenile southern elephant seals ArchiMer
Orgeret, Florian; Cox, Samantha; Weimerskirch, Henri; Guinet, Christophe.
Ontogeny of diving and foraging behavior in marine top predators is poorly understood despite its importance in population recruitment. This lack of knowledge is partly due to the difficulties of monitoring juveniles in the wild, which is linked to high mortality early in life. Pinnipeds are good models for studying the development of foraging behaviors because juveniles are large enough to robustly carry tracking devices for many months. Moreover, parental assistance is absent after a juvenile departs for its first foraging trip, minimizing confounding effects of parental input on the development of foraging skills. In this study, we tracked 20 newly weaned juvenile southern elephant seals from Kerguelen Islands for up to 338 days during their first trip...

Diet of four annual killifishes: an intra and interspecific comparison Neotropical Ichthyology
Laufer,Gabriel; Arim,Matías; Loureiro,Marcelo; Piñeiro-Guerra,Juan Manuel; Clavijo-Baquet,Sabrina; Fagúndez,César.
We examined the diet of 4 annual fishes, Austrolebias viarius, Austrolebias cheradophilus, Austrolebias luteoflammulatus and Cynopoecilus melanotaenia inhabiting temporal ponds of southeastern Uruguay, by analysis of stomach contents. Fishes were captured from fifty ephemeral ponds of Castillos Lagoon basin, in the region of the Humedales del Este. We identified 13099 individual prey items extracted from 669 stomachs of the four captured species. In the studied system, annual killifishes represents the most abundant and conspicuous top predators. Killifishes are generalist key predators at the ephemeral ponds of the studied system, consuming mostly aquatic items. Zooplancton represented the bulk of the diet in the four analyzed species, followed by eggs,...

Does body size of neotropical ant species influence their recruitment speed? Biota Neotropica
Godoy,Bruno Spacek; Camargos,Lucas Marques de.
Ants are one of the most important animal groups in tropical forests because of its abundance and number of species. An important characteristic of the group is the eusociality, which allows the occurrence of a recruitment behavior when food resource is found. However, there are two main questions regarding this behavior: (i) the recruitment is a product of environmental or phylogenetic pressures, and (ii) the recruitment speed is related to the body size of the ant species. In this work we addressed these two questions using 17 species of neotropical ants, in the Amazonic lowland dense rain forest. According to results, recruitment behavior is related to ant size, where smaller species exhibit this trait when finding a protein resource. However, species...

Feeding of diving predators and diel vertical migration of prey: King penguins' diet versus trawl sampling at Kerguelen Islands ArchiMer
Bost, Charles-andré; Zorn, T; Le Maho, Yvon; Duhamel, Guy.
The diving behavior and diet composition of King penguins were examined during summer 1995 at Kerguelen Islands. This was in relation to real-time estimations of diel prey availability during 2 sampling sessions totaling 10 d at sea. During daylight hours King penguins performed medium to deep dives of 120-250 m. At night, they dived no deeper than 60 m. Daytime, dusk and night-time sampling of prey was performed in the depth ranges corresponding to the depths of the penguins' dives in this study. The diversity in mesopelagic fish was found to be highest during the night at 0-50 m (15 vs 9 species during the day), and their number was up to 20-fold higher at these depths at night than during the day at the 150-250 m depth layer. The 3 myctophid species...

Females of Tapinotaspoides, a genus in the oil-collecting bee tribe Tapinotaspidini, collect secretions from non-floral trichomes (Hymenoptera, Apidae) Rev. Bras. entomol.
Melo,Gabriel A. R.; Gaglianone,Maria Cristina.
Harvesting of secretions from non-floral trichomes by females of Tapinotaspoides serraticornis is reported for the first time. The females exhibit a type of mopping behavior using the fringes of long, wavy setae along the posterior margins of their metasomal sterna. Our observations indicated a wide range of host plants used as sources for these secretions, including Waltheria (Sterculiaceae), Tibouchina (Melastomataceae), Sida (Malvaceae), Jacquemontia (Convolvulaceae), and unidentified species of Commelinaceae and Cyperaceae.

Foot-trembling behavior in Semipalmated Plover Charadrius semipalmatus reveals prey on surface of Brazilian beaches Biota Neotropica
Cestari,César.
Foot-trembling is a foraging technique normally performed by plovers and lapwings. It exposes preys, and may increase the likelihood of capture. Currently, no detailed description of this technique is available for the Semipalmated Plover Charadrius semipalmatus. This article described the foot-trembling behavior during wintering of this species in southeastern Brazilian beaches.

Foraging behavior and microhabitats used by black lion tamarins, Leontopithecus chrysopygus (Mikan) (Primates, Callitrichidae) Zoologia
Passos,Fernando de Camargo; Keuroghlian,Alexine.
Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats (dry palm leaves, twigs, under loose bark, in tree cavities). These microhabitats were spatially dispersed among different forest macrohabitats such as swamp forests and dry forested areas. These data indicated that the prey foraging behavior of L. chrysopygus was quite variable, and they used a wide variety of microhabitats, different of the other lion tamarin species.

Foraging pattern and harvesting of resources of subterranean stingless bee Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae: Meliponini) Pap. Avulsos de Zool. (São Paulo)
Barbosa,Fernando Mendes; Campos,Lúcio Antônio de Oliveira; Paixão,Joana Fidelis da; Alves,Rogério Marcos de Oliveira.
ABSTRACT Flight activity of bees is influenced both by environmental factors and by internal condition of the colonies. Information about external activity of bees is very important, because it provides data of the species biology, supplying subsidies for the use of these insects in the pollination of crops. The present work aim to evaluate the flight activity of Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae) in natural environment. This study was performed on the Instituto Federal do Norte de Minas Gerais, in the municipality Januária, Minas Gerais State. Two natural nests were observed. The activities of bees of the colonies were recorded three days each month, during the period of December 2011 to November 2012, totaling 924 observations....

Fruit-eating fishes of Banara arguta (Salicaceae) in the Miranda River floodplain, Pantanal wetland Biota Neotropica
Costa-Pereira,Raul; Severo-Neto,Francisco; Yule,Tamires Soares; Pereira,Ana Paula Tinti.
The role of fish as frugivorous and its ecological consequences are often neglected in ecological studies. However, the importance of the interaction between fish and plants is gaining force in scientific literature, and fish has been considered effective seed dispersers. The fruit-eating fish assemblage of Banara arguta (Salicaceae) was evaluated in Southern Pantanal wetlands. Nine species were reported consuming fruits, with different strategies to capture them. The distribution of B. arguta associated with the Pantanal floodplain and the presence of several species of fruit-eating fish, suggest that ichthyochory can be an important seed dispersal strategy to B. arguta.

Habitat complexity does not influence prey consumption in an experimental three-level trophic chain Iheringia, Sér. Zool.
Granzotti,Rafaela V.; Muniz,Carolina M.; Gomes,Luiz C..
ABSTRACT Habitat complexity influences species diversity and regulates trophic interactions, mostly by increasing resource partitioning within habitats and providing refuge for prey. The influence of habitat complexity on more than two trophic levels is not well understood, mainly because behavioral modifications of prey and predator may influence the outcome of trophic interactions. Thus, we conducted a two-factor experiment with a three-level trophic chain: a piscivorous fish [Hoplerythrinus unitaeniatus (Spix & Agassiz 1829)], an invertivorous fish (Moenkhausia forestii Benine, Mariguela & C. de Oliveira, 2009) and an aquatic macroinvertebrate (Chironomidae larvae). We measured prey consumption in low, intermediate and high habitat complexity,...

How do macrobenthic resources concentrate foraging waders in large megatidal sandflats? ArchiMer
Ponsero, Alain; Sturbois, Anthony; Desroy, Nicolas; Le Mao, Patrick; Jones, Auriane; Fournier, Jerome.
The relationship between foraging shorebirds, macrobenthos and sedimentary parameters has been widely studied across Western Europe. Megatidal areas have large zones uncovered when the water retreats. Consequently, in such cases, the tide also influences foraging activities. This paper examines the use of an intertidal space by waders to define how macrobenthic resource concentrates foraging activity of birds in a large megatidal sandflat. This approach combines accurate spatial distribution of waders (Oystercatcher, Eurasian curlew, Bar-tailed Godwit and Redknot) according to their activity with ecological/biological parameters. A differential exploitation of the flat is clearly shown, with macrobenthic biomass appearing as one of the main explanatory...

Importância de diferentes microhabitats no comportamento de forrageio por presas do mico-leão-preto, Leontopithecus chrysopygus (Mikan) (Mammalia, Callitrichidae) Zoologia
Passos,Fernando C.; Alho,Cleber J. R..
Prey foraging behavior in the Black Lion Tamarin, Leontopithecus chrysopygus (Mikan, 1823) was observed in the Caetetus Ecological Station, southeastern Brazil, during 550 hours of direct observations between December 1993 and February 1995. The scan sampling method was used to gather data. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats. The most important microhabitat used for prey foraging behavior was tree cavities (41% of the foraging observations), but palm trees (22%), bamboo (12%), vines (11%), bark (5%), seed pods of the "jequitiba" tree (4%), other places (3%) and epiphytes (2%) were also observed. Animal preys were frequently captured in understory...

Live coral predation by parrotfishes (Perciformes: Scaridae) in the Abrolhos Bank, eastern Brazil, with comments on the classification of species into functional groups Neotropical Ichthyology
Francini-Filho,Ronaldo B.; Moura,Rodrigo L.; Ferreira,Camilo M.; Coni,Ericka O. C..
Parrotfishes (Perciformes: Scaridae) represent a critical functional group on coral reefs because their intense herbivory activity helps in avoiding coral overgrowth by algae. Although feeding preferentially on algae and detritus, some parrotfish species also consume live corals, leading to detrimental effects that may offset the benefits of removing competitive seaweeds. Parrotfish species differ markedly in terms of jaw morphology, foraging activity and extent of substratum excavation, and are typically divided into three functional groups: browsers, scrapers and excavators. The recognition of species within each functional group helps to understand their relative effects in terms of bioerosion, coral fitness and survival, habitat alteration and...

Movements of bats (Mammalia, Chiroptera) in Atlantic Forest remnants in southern Brazil Zoologia
Bianconi,Gledson V.; Mikich,Sandra B.; Pedro,Wagner A..
We used mark and recapture techniques to evaluate movements of bats within and between three brazilian forest remnants. We captured bats with mist-nets in four 1 ha plots representing different degrees of isolation of riparian (two plots) and submontane (two plots) forests between July 2002 and June 2003. Using numbered aluminium tags, we marked 635 bats of seven species and 54 individuals of six species were recaptured. Overall, we recaptured Carollia perspicillata (Linnaeus, 1758) (short-tailed fruit bat) most frequently, especially in plots where they were banded in the riparian forest plots. These results suggest that this bat has restricted feeding areas, which are probably determined by the abundance of Piper Linnaeus (Piperaceae), its preferred food...

Pachycondyla obscuricornis as natural enemy of the spittlebug Deois flavopicta. Repositório Alice
SUGII, E.R.; GARCIA, M.A.; FONTES, E.M.G.; O'NEIL, R.J..
The objective of this work was to evaluate the potential control of the ant Pachycondyla obscuricornis Emery (Hymenoptera: Formicidae) on populations of nymphs of the spittlebug, Deois flavopicta Stal (Hemiptera: Cercopidae). Foraging behavior and prey consumption rate of P. obscuricornis were evaluated. Field data revealed that P. obscuricornis does not show aggressive behavior against individuals of the same species, when they are not carrying a prey; they can patrol distances larger than 10 m searching for prey, and they can build their nest as close as 1 m from each other. The ant has a solitary patrolling habit, there is no recruitment behavior, and individuals dislocate fast, browsing on soil and vegetation for prey. Predation rate on spittlebug...
