But prey with dazzle markings were also difficult to catch, particularly when they moved at higher speeds and against more heterogeneous backgrounds.
Despite this, the variation in responses was so striking that we expect that with the inclusion of more international experts with more heterogeneous backgrounds this variation would only become even more prominent.
Bond and Kamil (2006) [36] examined relationships between spatial heterogeneity and prey recognition by predators, and they concluded that colour morphs in less heterogeneous backgrounds were more readily detected than those in more heterogeneous backgrounds, even at the same level of background matching.
The synthetic variety EPS21 has a more heterogeneous background formed by Spanish, Italian, and French flints, and two "non-Reid" Corn Belt inbred lines.
However, the present study extends these findings to a population-based health survey of individuals from a more heterogeneous background than most cohorts of blood donors and to women included long before RA diagnosis.
In this experiment, we used a more complex, heterogeneous background and matching target to try to replicate the previous findings.
This claim is hard to maintain, however, in the face of the existence of the United Nations, the existence of states with more than a billion people of heterogeneous backgrounds, and the experience with the United States and the European Union.
Also, we were discouraged to include a VGP cell line in the study based on the rationale that cells from VGP tumors are more heterogeneous, as pointed out in the Background section.
50-70% of all TB patients prefer private healthcare, but this cohort is likely to be more heterogeneous than our sample in terms of economic backgrounds and education.
Possible explanations are offered by Vicente-Lorente and Suárez-González (2007), who summarize that due to their cultural background, foreign firms are characterized by more heterogeneous downsizing behaviors compared to domestic market participants, yielding ambiguous results.
The genetic heterogeneity due to crossing-over in F1 gametes can potentially result in offspring with different genetic backgrounds and hence in a population of animals genetically more heterogeneous than a population coming from a pure breeding.
