Nebraska Behavioral Biology Group, School of Biological Sciences, University of Nebraska, Lincoln, Nebraska 68588-0118, USA
Nature 415:609-13. 2002..Over successive generations, the moths evolved to become significantly harder to detect, and they showed significantly greater phenotypic variance than non-selected or frequency-independent selected controls...
- Serial reversal learning and the evolution of behavioral flexibility in three species of North American corvids (Gymnorhinus cyanocephalus, Nucifraga columbiana, Aphelocoma californica)Alan B Bond
School of Biological Sciences, University of Nebraska, Lincoln, NE 68588 0118, USA

- Spatial heterogeneity, predator cognition, and the evolution of color polymorphism in virtual preyAlan B Bond
Center for Avian Cognition, School of Biological Sciences, University of Nebraska, Lincoln, 68588, USA
Proc Natl Acad Sci U S A 103:3214-9. 2006..The result was less apostatic selection and lower phenotypic variability. The evolution of polymorphism in camouflaged prey depends on a complex interaction between habitat structure and predator cognition...

Center for Avian Cognition, School of Biological Sciences, University of Nebraska, Lincoln, Nebraska 68588, USA
Nature 430:778-81. 2004..These results directly demonstrate that animals use transitive inference in social settings and imply that such cognitive capabilities are widespread among social species...
- Sociality and the evolution of intelligenceAlan C Kamil

Trends Cogn Sci 8:195-7. 2004..showed that highly social female baboons have higher reproductive success than less social females. Taken together, these studies provide strong evidence for the importance of social context in cognitive evolution...
- Interference effects in the memory for serially presented locations in Clark's nutcrackers, Nucifraga columbianaJody L Lewis
Department of Psychology, University of Nebraska Lincoln, Lincoln, NE, USA
J Exp Psychol Anim Behav Process 32:407-18. 2006..This finding demonstrates that nutcrackers are susceptible to proactive and retroactive interference during the recall of spatial information...
- Clark's nutcrackers (Nucifraga columbiana) and the effects of goal--landmark distance on overshadowingAleida J Goodyear
School of Biological Sciences, University of Nebraska, Lincoln, NE, USA
J Comp Psychol 118:258-64. 2004..Search error in tests with single landmarks was compared both within and across groups. Results demonstrated that both relative and absolute goal-landmark distances are important in spatial search...

University of New Hampshire, Psychology Department, Conant Hall, Durham, NH 0382, USA
Learn Behav 33:59-66. 2005..The results suggest that differences in spatial memory among these species are not related to differences in fine-grained perception...

Department of Psychology, University of Alberta, Edmonton, Canada
J Comp Psychol 117:123-32. 2003..Error magnitude increased with novel extrapolated interlandmark distances but not with novel interpolated distances. Results suggest modest geometric rule learning by pigeons...
