A previously undescribed system of differential food
storage in replete forms of the honey ant, Myrmecocystus
mexicanus Wesmael, is reported. Certain repletes store lipid as glycerol and cholesterol esters associated with
sugar solutions containing glucose, fructose, and maltose.
In developed country markets, the consideration of consumer wants has not been prominent hitherto in aquaculture production decisions. Like capture fisheries aquaculture has been product driven. This supply-side focus reflects an emphasis upon technical solutions to the production and capacity problems of high unit value (HUV) species culture. Whilst this...
As the various mechanisms of fisheries resources management have matured, fishermen increasingly have responded by devising and developing different forms of collective representation. Within the European Union (EU), Producer's organisation (POs) provide a voluntary organisational structure which has evolved since its inception in the 1970s. During the intervening period, POs...
With heightened media attention on the poor state of world fish stocks and the environmental impacts of aquaculture production methods, both governments and seafood industries are keen to demonstrate support for improved management measures. This paper includes results from a DFID funded project concerned with seafood certification, ecolabelling and developing...
Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion
resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of ~475 °C and below, limits upper service temperatures
for many applications. New lean grade duplex alloys have improved thermal stability...
