This study was designed to replicate the effects that they found among herding and farming societies and to either support or refute the claim regarding foraging societies.
Additional data logger studies (2008 2010) were conducted on African penguins and globally endangered bank cormorants Phalacrocorax neglectus following the NIMPA's design phase to test the adequacy of its boundaries regarding foraging ranges.
JCS contributed to the design of the study, provided expertise regarding foraging theory, was secondary supervisor to MD and reviewed drafts of the manuscript.
However, questions remain regarding the foraging behaviour of these shearwaters in the high latitude regions of the Southern Ocean, including their apparent lack of use of the Polar Front zone directly south of New Zealand, and the overlap of their foraging ranges with those of conspecifics such as short-tailed shearwaters [2].
Food odors in particular provide crucial information regarding potential foraging sites.
Isotopic studies have revealed new details regarding the foraging ecology of marine vertebrates, such as trophic position, reliance on nearshore or offshore food sources, the relative importance of different prey species, and interspecific or intraspecific resource partitioning [ 11- 13].
To cite a specific example, I would regard sustainable forage production as the weakest in ruminant development in both rangeland and integrated crop/livestock production systems.
Results are discussed regarding the impact of forage resource sharing on the resilience of these grazing systems.
The decisions made by individuals within a group, for example, regarding where to move, forage, or interact with conspecifics, are governed by their current internal state [3], [4] and sensory information they can receive [5], [6], [7], [8].
Even in the 1980s, there were complaints by herders regarding the extent of forage consumption by kiang and consequent competition with livestock, and demands that the government should "drive the kiang back into Tibet" (Fox and others 1991).
