Sentence examples for value of prey from inspiring English sources

The change in the estimated value of prey with the Model/Mimic signal caused by forgetting is defined by the following algorithm (as in [18]): <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0003411.e002.PNG" class= inline-graphic"/> where φ is the forgetting parameter (default value, 0.02), as in [18].

Similar facts apply to triglyceride concentrations: They can vary significantly with diet (in particular seasonal caloric value of prey and time of last food intake) among different populations and even between individuals [ 22].

Overall, these results demonstrate that presenting human 'predators' with prey images on computer screens can provide reliable information on the protective value of prey colour patterns under natural conditions.

Although we know little about the toxic effects of quinine, or whether it affects the way in which predators learn about the energetic and nutritional value of prey, there are a number of reports of other toxins having negative effects on learning (Dudai et al. 1987; Levin et al. 2003).

Figure 1 (a), (b) The time series diagrams with two initial values of prey and predator, respectively.

Figure 2 (a), (b) Time series diagrams with two initial values of prey (x_{i}) ((i = 1,2 )), respectively.

One sub-population feeds mostly on y (i.e. contains mostly y-terms), prospering on prey with a high y-value, and a predator feeding best on the x-value of prey has the opposite preference.

Scavengers are only implicitly evaluated on how well they complement predators and only see the original values of prey.

Our study provides the clearest evidence to date that using humans as 'predators' in detection experiments may provide reliable information on the protective values of prey colour patterns and of natural selection and microevolution of camouflage in the wild.

In many previous simulation models, predators repeatedly learn and forget the value of the prey based on experience, and the estimated prey value directly determines the motivation of the predator to attack the prey [18] [20].

Results in Table 1 and Figs. 1, 2 and 3 showed that the recurrent selection of this trait for 12 inbreeding generations contributed to the increase of the values of preying potential of the 3rd larval instar with significant differences from 24.20 nymphs/day in Po to 27.03 at F3 and to 28.18 at F9 and with insignificant differences between F9 and F12.
