| ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nursery phase, and subsequently establish thermoneutrality ranges. The experiment was conducted on a pig farm where T, relative humidity (RH), and SPL data were recorded between 9 am-5 pm for 42 days. The association between SPL and T in nursery phase piglets was verified; for thermal comfort to be possible, SPLs were 56.3 to 60.3 dB. The SPLs were subsequently used in predictor equations of ratios, and... |

| Seasonal growth of juvenile oysters (Crassostrea gigas) kept in an intensive upwelling system was studied from 1984 to 1986 in 60 to 90-day growth experiments. Saline ground water was used to produce Skeletonema costatum which was injected as food into the water supplying the upwelling system. Oyster density, water flow, phytoplankton concentration, temperature and frequency of food addition were controlled. Oyster growth was analysed with multidimensional contingency tables and correspondence analysis. The factors, in order of decreasing influence on growth, were temperature, food concentration and oyster density. A rearing strategy was deduced from the growth analysis for summer and winter. In summer, the density of 120,000 oysters/m2, the flow rate of... |

| Artificial production from natural spawners could be a way of getting big quantities of spat of Pecten maximus, ln the method described, larval phase (until a size of 250 microns) occurs in a hatchery, post-Iarval phase (from 250 µ until 3 millimeters) in a nursery, and first growth period directly into the sea (from 2 mm to a size of 25-30 mm), The fifst results obtained, production of several thousand of individuals good enough for reseeding, seem to be transposable to a larger scale. |

| During large-scale surveys for soilborne Phytophthora species in forests and semi-natural stands and nurseries in Europe during the last decade, homothallic Phytophthora isolates with paragynous antheridia, semipapillate persistent sporangia and a growth optimum around 25 °C which did not form catenulate hyphal swellings, were recovered from 39 host species in 16 families. Based on their morphological and physiological characters and the similarity of their ITS DNA sequences with P. citricola as designated on GenBank, these isolates were routinely identified as P. citricola. In this study DNA sequence data from the internal transcribed spacer regions (ITS1 and ITS2) and 5.8S gene of the rRNA operon, the mitochondrial cox1 and β-tubulin genes were used in... |

| Human activities facilitate coastal habitat transformation and homogenization. The spread of marine invasive species is one example. This in turn may inluence ish recruitment and the subsequent replenishment of adult assemblages. We tested habitat complexity effect on ish (Teleostei) recruitment by experimentally manipulating meadows of the habitat-forming invasive macroalga Caulerpa taxifolia (Chlorophyta). Among the fourteen ish species recorded during the experiment, only two labrids (Coris julis and Symphodus ocellatus) settled in abundance among these meadows. Patterns in the abundance of these juveniles suggested that reduced tri-dimensional meadow complexity may reduce habitat quality and result in altered habitat choices and / or differential... |

| Apesar do desenvolvimento técnico e operacional dos viveiros clonais ao longo dos anos, os sistemas de retenção de resíduos e efluentes do processo produziram. O objetivo da pesquisa é avaliar o uso de efluente oriundo de minijardim clonal como adubação em mudas clonais de eucalipto. Foram utilizados os clones AEC 144, GG 100 e VM 01. O experimento foi instalado, o envolvimento de diferentes frequências e lâminas de fertirrigação residual, bem como a utilização da adulação convencional, pelo método de tratamento respiratório, sem uso de Adubação. Para o clone AEC 14, os tratamentos com aplicações diárias de efluente, associados às lâminas de 2 e 3 mm, proporcionaram, em geral, maior qualidade das mudas. Resultado parecido foi observado para o clone VM 01,... |

| The essential oil extracted from mustard (Brassica rapa) seeds was evaluated for its effect on suppression of Rhizoctonia solani growth in vitro, and in field soils, for reducing saprophytic substrate colonization and seedling damping off and blight using snap beans as indicator plant, the in vitro growth was completely inhibited at a concentration of 50 mul/l. The saprophytic substrate colonization in soils 24 h after treatment was drastically reduced to 45% at 150 mul/kg soil concentration, in contrast to 100% colonization at concentrations of 0, 50, or 75 mul/kg. This recovery rate gradually declined to 6% and 60%, respectively, in nine days. A control of pre and post-emergence seedling damping off and blight in common beans (Phaseolus vulgaris),... |

| Little attention has been paid to flatfish parasitism as a potential factor of variation in year-class strength. The aim of this study was to evaluate the relationship between parasitic infection and nutritional condition of young-of-year (YOY) common sole. Sole were collected monthly from May (early settlement) to November 2004 in a mussel pole culture area, using a push-net or a trawl, and dissected for parasite identification and counts. Total lipids were extracted from the whole body and lipid classes quantified. Triacylglycerols to sterols (free form) ratio (TAG/ST) was used as an index of nutritional status. Digenean metacercariae infection, characterized by two dominant genera, displayed clear seasonal dynamics and the highest records yet reported... |

| This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death. Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with... |

| Mycorrhizal fungus inoculum produced on-farm can be used during production of woody plant seedlings to reduce costs associated with purchase of commercial inoculant and fertilization. This study aimed to test the efficiency of a mycorrhizal inoculant produced on-farm to promote growth and nutrition of woody species in combination with different levels of phosphorus. Plants were submitted to different treatments of phosphorus (0, 40 and 80 mg P/dm3) and mycorrhizal inoculation (uninoculated, and inoculation with Rhizophagus clarus [Rc] or Claroideoglomus etunicatum [Ce]). Species included were Luehea divaricata, Centrolobium robustum, Schinus terebinthifolius, Garcinia gardneriana, Cedrella fissilis, and Lafoensia pacari. The inoculum was produced using the... |
