At the end of the selection process, we separately introduced each morph type (black and brown) to a mixture of resources, to test for resource preference.
First, local foraging opportunities shape the difficulty of preference development both by shaping familiarity bias formation and the ambiguity of feedbacks when digesting mixtures of resources.
Many systems consist of a mixture of various resource types that together support better performance relative to those with a single resource type.
Second, we defined a list of detailed indicators that could help our analysis (including data about the mixture of financial resources available, the numbers of users, the average cost of social care intervention per user, and provider characteristics).
In the first generation after secondary contact, when the two morphs were kept together on a mixture of the two resource types, we found a significant deficit of heterozygotes in 13 out of 18 cases (mean I = 0.20±0.043, mean ± SE heterozygote deficiency index; for details on each line, see Figure 2a where intervals not including zero indicate that the I-value is significant).
> During preference development, individuals cannot determine the contribution of different resources to digestive feedbacks because digestive feedbacks are averaged over mixtures of digested resources.
The twilight of the twentieth century is driven by a mixture of technology and resources very like that which drove nineteenth-century America.
The island is calling for proposals that could use a mixture of its local resources – solar power, wind energy, biomass and even ocean energy – and combine those with battery storage, smart software and the existing diesel back-up.
The country's future energy should come from a balanced mixture of all these resources to steadily decrease its reliance on imported oil.
Moreover, the digestion of resource mixtures complicates preference development (e.g., Duncan and Young 2002), probably because it is difficult to untangle the contribution of resources to digestive feedbacks.
Moreover, in the algorithm, feedbacks from digestion of resource mixtures are averaged over all resources consumed, making feedbacks ambiguous, as appears to be the case in some diet development studies (e.g., Duncan and Young 2002).
