| During the last 15 years, northern European hake (Merluccius merluccius) has increased in abundance, and its spatial distribution has expanded in the North Sea region in correlation with temperature. In a context of global warming, this spatial shift could impact local trophic interactions: direct impacts may affect forage fish through modified predator–prey interactions, and indirect impacts may materialize through competition with other resident predators. For instance, North Sea saithe (Pollachius virens) spatial overlap with hake has increased while saithe spawning-stock biomass has decreased recently notwithstanding a sustainable exploitation. In this context, we investigated the range of potential impacts resulting from most recent hake emergence in... |

| There is growing pressure for farmers in countries such as Uganda to accelerate their efforts to commercialize production in the face of increasing market competition from neighboring countries and across the world. To assist farmers, a new generation of low cost market information services is being developed that takes advantage of information and communication technologies such as FM radios, mobile phones, and internet-based communications systems, to enable farmers to monitor and adjust to dynamic market conditions in local, national, and export markets. Although there is much interest in market information from farmers, other market chain actors, and service providers, there is skepticism from funding agencies to support such services over the long... |

| ABSTRACT The production of tomato seedlings is conducted on commercial substrates with adequate properties for the good formation of the aerial part and root. The Spent Mushroom Substrate, or SMS, presents advantages over commercial substrates regarding the quality of the vegetable seedlings, which may be provided by the presence of a rich microbiota, bringing higher balance and competition with pathogenic microorganisms, in addition to the biological control of pathogens and nematodes. It is important to know the microbiota present in this material and its relation to the plant, in order for this association to occur in the best manner possible. This work had the objective of identifying the microbiota present in the rhizosphere of tomato seedlings... |
