| Between april 2005 and May 2006, according to the pressuposts of line transect methodology, census were carried to estimate abundance and population density of Callicebus nigrifrons Spix, 1823 (Pitheciidae) in Cantareira State Park, State of São Paulo, southeastern Brazil (23°23'42"S, 46°35'27"W). After 275.80 Km of census sampling effort, the titis were the second most abundant primate species, presenting an abundance index of 1.4 groups for each 10 km walked and a density estimate of 12.21 ind./km² (ranging between 8.45 a 17.63 ind./km²). The collection of ancillary data during the census allowed the determination of diet and habitat use by the titis groups, and results show a relative adaptability to disturbed habitats. |

| Between January 2007 and December 2010, the abundance of medium-sized mammals was studied, with special focus on the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782), at four locations in southern Brazil. In this study, transect line methodology was used to obtain data for Distance Analyses. Transects were traveled by car at night, searching with spotlights along the edges of secondary roads in agricultural landscapes. Along 1,811 km, we obtained 620 observations of 20 mammal species. The most common species was the exotic European hare, Lepus europaeus (Pallas, 1778); the highest abundance estimated for South America was observed in one of the study areas, where its density was estimated as 32 individuals/km². Carnivores were the most commonly... |

| La abundancia y madurez sexual de la piangua Anadara similis fue analizada mensualmente entre septiembre de 2009 y agosto de 2010 en el archipiélago de La Plata, Bahía Málaga, Pacífico colombiano. La madurez sexual se analizó a nivel macroscópico mediante la observación del tejido reproductivo en fresco y microscópico por medio de métodos histológicos estándares. Se estimó una densidad media de 0.130 ± 0.098 ind/m2 y una talla media de 42.30 ± 5.00 mm. Los meses de mayor densidad fueron mayo (0.295 ind/m2) y agosto (0.195 ind/m2). La talla media de madurez sexual fue de 41.8 ± 4.5 mm y talla media de 41 mm donde 50% de la población ha tenido mínimo un desove (L50%). Se registraron picos máximos reproductivos durante marzo (83.3%) y abril (75.0%), aunque... |

| This study deals with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : it relies on a survey achieved in july 2001, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according to prices and availability of oysters supplies. The duration until marketable size and mean mortalities seem to have increased since a preceding inquiry in 1986. The main constraint, affecting priorly the south border... |

| Soils of the coastal plains of Rio Grande do Sul, Brazil, are affected by salinization, which can hamper the establishment and development of crops in general, including rice. The application of high doses of KCl may aggravate the crop damage, due to the high saline content of this fertilizer. This study aimed to evaluate the effect of K fertilizer management on some properties of rice plant, grown in soils with different sodicity levels, and determine which attribute is best related to yield. The field study was conducted in four Albaqualfs with exchangeable Na percentages of 5.6, 9.0, 21 and 32 %. The management of KCl fertilizer consisted of the application of 90 kg ha-1 K2O broadcast, 90 kg ha-1 K2O in the row and 45 kg ha-1 K2O in the row + 45 kg ha-1... |

| O presente trabalho teve por objetivo basico estudar a associacao entre a densidade basica da madeira (dbm) e o diam etro a altura do peito (dap) em uma populacao base de Eucalyptus camaldulensis, instalada em abril de 1986, em Selviria-MG, obedecendo a um delineamento em blocos casualizados, tendo 25 tratamentos (matrizes, 10 repeticoes, e uma arvore por aprcela,, no espacamento de 4,0 x 4,0 metros. O estudo envolveu a obtencao de estimativas de parametros geneticos para o dap e a dbm. Aos 7 anos apos o plantio as medias do dzap e da dbm foram de: 19,65 cm e 0,666 g/cm cubico, respectivamente. As estimativas de ehrdabilidade, ao nivel de media de familias, foram de 0,49 para o dap e de 0,55 para a dbm. O estudo da resposta correlacionado, envolvendo essas... |

| Much is known in very broad terms about the distribution of deep-sea fishes, but information on fine-scale habitat selection and behaviour in the largest living space on earth is still rare. Based on video sequences from 4 dives performed with the manned submersible 'Nautile' at depths between 400 and 2000 in in the Bay of Biscay, NE Atlantic, we studied the behaviour of co-occurring slope-dwelling deep-sea fishes. Five different habitats were identified according to depth range or topographical and hydrological characteristics. For each fish species or genus that could be identified, estimates of absolute abundance were provided. The most frequently occurring species, round-nose grenadier Coryphaenoides rupestris, blackmouth catshark Galeus melastomus,... |

| Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m-2 (D70); 100 animals m-2 (D100), Control; 150 animals m-2 (D150) and 200 animals m-2 (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was... |
