| Se ubicaron 29 poblaciones naturales de Pseudotsuga menziesii en Hidalgo, Tlaxcala y Puebla, con un estimado de 9,029 árboles adultos, en 682 ha que se ubican desde 2,450 a 3,400 m s.n.m. Las localidades son de clima templado, con temperatura media anual de 10.1 a 14.0 °C y precipitación de 611 a 1,109 mm anuales. Pseudotsuga convive con Abies religiosa y varias especies de Pinus y Quercus, en exposiciones N, NO y NE. Los suelos son de pH ligeramente ácidos, ricos en materia orgánica y clase textural franco-arenosa o franca. El tamaño poblacional varía de 4 a 1,450 árboles maduros; 11 de éstas menos de 100 individuos adultos, con poca repoblación natural en todas ellas. Existe gran fragmentación en su distribución natural. Con base en un análisis de... |

| The oregano is a plant, rich in essential oil and very used as spice in the preparation of foods. The objective of this paper was to analyze the viability of irrigation for oregano in Presidente Prudente, São Paulo state, Brazil, including economic risk factors, their effect on irrigation total cost, as well as the different pumping kinds. The Monte Carlo simulation was utilized to study the economic factors: fixed cost, labor, maintenance, pumping and water. The use of irrigation for the oregano in the region of Presidente Prudente is indicated because of its economic feasibility and the reduced risks. The average values of the benefit/cost for all water depths tested were higher than 1, indicating viability. The use of irrigation promoted lower risks... |

| Mortality of young Pacific oysters Crassostrea gigas associated with the ostreid herpesvirus 1 (OsHV-1) is occurring worldwide. Here, we examined for the first time the effect of salinity on OsHV-1 transmission and disease-related mortality of C. gigas, as well as salinity-related effects on the pathogen itself. To obtain donors for OsHV-1 transmission, we transferred laboratory-raised oysters to an estuary during a disease outbreak and then back to the laboratory. Oysters that tested OsHV-1 positive were placed in seawater tanks (35‰, 21°C). Water from these tanks was used to infect naïve oysters in 2 experimental setups: (1) oysters acclimated or non-acclimated to a salinity of 10, 15, 25 and 35‰ and (2) oysters acclimated to a salinity of 25‰; the... |

| The PANDA project aims to establish a permanent network of aquatic animal health specialists (researchers and diagnosticians) to provide a forum for the debate of issues concerning diseases in European aquaculture, and to communicate the results of these discussions to the European Commission with provision of advice on EU policy and legislation for aquatic animal health. PANDA consists of five scientific work packages: risk analysis, epidemiology, diagnosis, environmentally safe strategies for disease control, training in research and diagnostics. These work packages are lead by PANDA consortium members, supported by small task force of specialists, with wider input from experts registered in the PANDA network. Focused workshops and ongoing online... |

| Developed for carrying out risk assessments under the European Commission (EC) Council Regulation No 708/2007 concerning the use of alien and locally absent species in aquaculture (ASR), the European Non-native Species in Aquaculture Risk Assessment Scheme (ENSARS) is briefly summarised, and the ‘Organism’ module is applied to the 24 species listed in ASR's Annex IV. Four other ENSARS modules (Infectious Agent, Facility, Pathway, and Socio-economic) were used to assess two case study species (European catfish Silurus glanis L. and red swamp crayfish Procambarus clarkii Girard). No Annex IV species was categorised as low risk, 10 as moderately low risk, 12 as medium risk, two as moderately high risk and none as high risk. The results are discussed and... |

| The intertidal zone is characterized by a sharp vertical gradient of environmental stress, which structures species distribution and their interactions. Few studies, however, have examined the influence of tidal height on host–pathogen interactions. Here, we investigated how the tidal height influence outbreak of the Ostreid herpesvirus type 1 (OsHV-1) affecting the Pacific oyster. A volunteer network composed of 20 oyster growers monitored the survival of 28 batches of oysters during an epizootic event in Southern Brittany, France. Oysters were spat from wild collection or hatchery production. The sampling sites were spread over a 150-km2 area with a tidal height ranging from 0.98 to 2.90 m. Concomitantly, we followed survival of oyster spats in relation... |

| A total of ten crayfish species have been observed in the Netherlands: one native species (the Noble crayfish Astacus astacus) and nine invasive species. Six invasive species are established (narrow-clawed crayfish Astacus leptodactylus, signal crayfish Pacifastacus leniusculus, spiny-cheek crayfish Orconectes limosus, virile crayfish Orconectes , white river crayfish Procambarus acutus and red swamp crayfish Procambarus clarkii), the status of one invasive species (marbled crayfish Procambarus sp.) is currently unclear. Two invasive species (the stone crayfish Austropotamobius torrentium and the redclaw Cherax quadricarinatus) have been recorded only once. The remarkable expansion of some of these invasive crayfish has raised questions about the possible... |
