An Assessment of the Fuel Use Intensity of the Pacific Bluefin Tuna Fattening Operations in Mexico

An Assessment of the Fuel Use Intensity of the Pacific Bluefin Tuna Fattening Operations in Mexico   With the industrialization of fishing practices, many global fish stocks have been over-fished either to or near the point of collapse. At present, both open and closed-cycle aquaculture operations exist as a means of supplementing the supply of… Details

Investigating predator-prey dynamics of leatherback sea turtles and jellyfish in Atlantic Canadian waters

Investigating predator-prey dynamics of leatherback sea turtles and jellyfish in Atlantic Canadian waters The leatherback sea turtle (Dermochelys coriacea), classified as endangered in Canadian waters, faces several natural and anthropogenic threats. They are a highly migratory species, traveling between tropical waters to nest, and northern temperate waters to feed. There is a large foraging population of… Details

The effects of temperature on spatial patterns of trophic control in large marine ecosystems

The effects of temperature on spatial patterns of trophic control in large marine ecosystems Marine ecosystems may be structured according to resource availability (“bottom-up” control), or by predation (“top-down” control).  Recent studies have found that temperature is a particularly strong correlate of trophic control, following a non-linear relationship with resource control dominant in areas of… Details
