Proc Biol Sci 271:361-5. 2004..7 and 12.9, similar to values recorded in diurnal navigators. These results agree with earlier results suggesting that the detection and analysis of polarized skylight is similar in diurnal and nocturnal insects...

Department of Biology, University of Lund, Helgonavagen 3, 223 62 Lund, Sweden
Philos Trans R Soc Lond B Biol Sci 366:697-702. 2011..This indicates that, in nocturnal species, the sensitivity of the optical polarization compass can be greatly increased without any loss of precision...

Department of Biology, University of Lund, S 22362 Lund, Sweden
Annu Rev Entomol 56:239-54. 2011..Exactly where in the visual system this summation takes place, and the nature of the neural circuitry that is involved, is currently unknown but provides a promising avenue for future research...

ARC Centre for Excellence in Vision Science, Research School of Biological Sciences, Australian National University, P O Box 475, Canberra, ACT, 2601, Australia
Anim Cogn 11:683-9. 2008..It appears that bees can navigate to food sources by maintaining a running count of prominent landmarks that are passed en route, provided this number does not exceed four...
- Twilight orientation to polarised light in the crepuscular dung beetle Scarabaeus zambesianusMarie Dacke
Department of Cell and Organism Biology, University of Lund, Helgonavagen 3, S 223 62 Lund, Sweden
J Exp Biol 206:1535-43. 2003..The fan-shaped arrangement of receptors over the dorsal rim area was previously believed to be an adaptation to polarised light analysis, but here we argue that it is simply a consequence of the way that the eye is built...

Centre for Excellence in Vision Science, Research School of Biological Sciences, Australian National University, PO Box 475, Canberra, ACT 2601, Australia
J Exp Biol 210:845-53. 2007..These findings raise important questions about how honeybee recruits navigate reliably to find the food sources that are advertised by scouts...
- Honeybee navigation: following routes using polarized-light cuesP Kraft
Queensland Brain Institute, The University of Queensland, Saint Lucia, Queensland 4072, Australia
Philos Trans R Soc Lond B Biol Sci 366:703-8. 2011..The results show that bees can learn this task, thus demonstrating directly, and for the first time, that bees are indeed capable of using the polarized-light information in the sky as a compass to steer their way to a food source...
- Bearing selection in ball-rolling dung beetles: is it constant?Emily Baird
Department of Biology, Lund University, Sölvegatan 35, 22362, Lund, Sweden
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 196:801-6. 2010..This strategy allows beetles to make an efficient escape from the dung pile while minimizing the chance of encountering competition...
- Visual training improves underwater vision in childrenAnna Gislén

Department of Cell and Organism Biology, Zoology Building, Lund University, Helgonavagen 3, Sweden
Curr Biol 13:833-6. 2003..This extreme reaction-which is routine in Moken children-is completely absent in European children. Because they are completely dependent on the sea, the Moken are very likely to derive great benefit from this strategy...

Lund University, Department of Biology, Helgonavagen 3, 22362 Lund, Sweden
J Exp Biol 213:1625-32. 2010..By measuring optic flow over a visual field that has a low minimum viewing angle, bumblebees are able to detect and respond to changes in the proximity of the environment well before they are encountered...
