Spatial and temporal operation of the Scotia Sea ecosystem: a review of large-scale links in a krill centred food web
The combination of historical perturbation and rapid regional change highlights that the Scotia Sea ecosystem is likely to show significant change over the next two to three decades, which may result in major ecological shifts. Expand
Long-term changes in deep-water fish populations in the northeast Atlantic: a deeper reaching effect of fisheries?
Overall fish abundance fell significantly over this time, considerably deeper than the maximum depth of commercial fishing, which would indicate that the impacts of fisheries can be transmitted into deep offshore areas that are neither routinely monitored nor considered as part of the managed fishery areas.

The thermohaline expressway: the Southern Ocean as a centre of origin for deep‐sea octopuses
It is suggested that the initiation of the global thermohaline circulation provided a mechanism for the radiation of Southern Ocean fauna into the deep sea and acted as an evolutionary driver enabling the Southern Ocean to become a centre of origin for deep‐sea fauna. Expand
Bathymetric distribution of some benthic and benthopelagic species attracted to baited cameras and traps in the deep eastern Mediterranean
A series of baited camera and trap experiments in the eastern Mediterranean Sea between 1500 and 4264 m depth attracted a variety of opportunistic scavengers, with species composition changing with increasing depth, and the diversity of bait-attending fauna declined with increasing Depth. Expand
The Patagonian toothfish: biology, ecology and fishery.
Patagonian toothfish (Dissostichus eleginoides) is a large notothenioid fish that supports valuable fisheries throughout the Southern Ocean, and studies using genetics, biochemistry, parasite fauna and tagging indicate a high degree of isolation between populations. Expand
Trends in body size across an environmental gradient: A differential response in scavenging and non-scavenging demersal deep-sea fish
Investigation of contrasting relationships between size and depth in the scavenging and predatory demersal ichthyofauna of the North-east Atlantic finds larger size in scavengers permits higher swimming speeds, greater endurance as a consequence of larger energy reserves and lower mass specific metabolic rate, factors that are critical to survival on sporadic food items.

Vision in lanternfish (Myctophidae): adaptations for viewing bioluminescence in the deep sea
The sensitivity hypothesis seeks to explain the correlation between the wavelength of visual pigment absorption maxima (lambda(max)) and habitat type in fish and other marine animals in terms of theExpand
The fate of cetacean carcasses in the deep sea: observations on consumption rates and succession of scavenging species in the abyssal north-east Atlantic Ocean
The fate of cetacean carcasses in the deep sea was investigated using autonomous deep–sea lander vehicles incorporating time–lapse camera systems, fish and amphipod traps, with a succession in the species composition of amphipods, with the specialist necrophages being replaced by more generalist feeders of the Orchomene species complex.

Distribution of deep-water benthic and bentho–pelagic cephalopods from the north-east Atlantic
The distribution of deep-water (150–4850 m) benthic and bentho–pelagic cephalopods in the north-east Atlantic is described, based on 592 specimens collected from commercial and research trawling.Expand
Food web dynamics in the Scotia Sea in summer: A stable isotope study
The pelagic food web of the Scotia Sea was studied by analysing natural abundances of nitrogen and carbon stable isotopes of primary producers and pelagic consumers, sampled from the seasonal ice edge in the south to the Antarctic Polar Front in the north, indicating the existence of the classic short food chain of POM–suspension feeder–vertebrate predator.
