The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

The marine fisheries production from African coastal countries, combined with that of freshwater production of
the continent is estimated to be 6 millions metric tons, corresponding only 5 % of the total world production. Africa's
contribution to fisheries products (1,5 %) is insignificant compared to that of world commerce which...
Bacteria in the class Alphaproteobacteria have a wide variety of lifestyles and physiologies. They include pathogens
of humans and livestock, agriculturally valuable strains, and several highly abundant marine groups. The ancestor of
mitochondria also originated in this clade. Despite significant effort to investigate the phylogeny of the
Alphaproteobacteria with a...

Multiple stressors are currently threatening honey bee health, including pests and pathogens. Among honey bee pathogens, Nosema ceranae is a microsporidian found parasitizing the western honey bee (Apis mellifera) relatively recently. Honey bee colonies are fed pollen or protein substitute during pollen dearth to boost colony growth and immunity against...
