Optimal foraging decisions, for example, depend upon the ability of a forager correctly to perceive the relative resource value of different patches of food, in light of associated costs of foraging such as threats of predation (Stephens et al. 2007).
The growth advantage of first arrivals also increased with local shelter abundance in the stream, which can be expected if a higher resource value of the habitat results in a higher defence motivation.
Given the critical resource values of riparian zones, additional data are needed to understand interactions between fire and riparian ecosystems, and how riparian zones affect spatial and temporal patterns of fires at the landscape scale.
(1) The appropriate Federal agency may close an area on a temporary or permanent basis to use of aircraft, snowmachines, motorboats or nonmotorized surface transportation only upon a finding by the agency that such use would be detrimental to the resource values of the area.
They fail when partners don't start with a shared understanding of the resources' value.
For example, capturing and measuring levels of resources, values, beliefs and power of diverse actors is difficult; also, the notion of 'power' fundamental to policy analysis is a highly contested concept.
Economic outcomes are the net bundle of resources forgone due to an intervention valued at the opportunity cost of those resources (the value of their next best use or "opportunity").
The global (among all types of resources) availability value of a remote node may be obtained through a simple additive model [15].
Nonetheless, given limited DoD funding and resources, the value of which target populations are best matched for which objective under an AFHSC-GEIS mission needs further consideration.
Att present China's coal price can't reflect the true cost of coal resources and the value of resources isn't adequately compensated, for which absence of full cost of coal resources is mainly responsible.
