Origin and biomimicry of weak iridescence in black-billed magpie feathers

Han, C. H., Kim, H. B., Jung, H. H., Lee, S. I., Jablonski, P. J. & Jeon, H. S. The feathers of the black-billed magpie exhibit distinct iridescence, which is much weaker than that of other bird feathers well known to display structural colors. Close examination of the cross-sectional microstructures of the magpie

Mechanics of jumping on water

Kim, H. Y., Amauger, J., Jeong, H. B., Lee, D. G., Yang, E. J., Jablonski, P. G. Some species of semi-aquatic arthropods including water striders and springtails can jump from the water surface to avoid sudden dangers like predator attacks. It was reported recently that the jump of medium-sized water striders is a

Characterisation of the major carotenoids in the plasma of the Eurasian magpie (Pica pica) nestlings

 Lee, S. I., Baek, M. J., Choe, J. C., & Jablonski, P. G. Since carotenoids can serve as antioxidants and/or immune stimulants, it has been assumed that deposition of carotenoids in feathers or bills can reveal the health status in birds. In order to study the function of carotenoids as signals or immune

Intimidating courtship and sex differences in predation risk lead to sex-specific behavioural syndromes

Han, C. S., Jablonski, P. G., & Brooks, R. C. Many species have evolved a suite of anti-predator defences, rather than a single defence. These multiple defences may operate in synchrony or separately at different stages of predation sequence to protect the prey. However, empirical documentation on how multiple defences, as a whole,

Multiple lines of anti-predator defence in the spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae)

Kang, C. K., Moon, H. M., Sherratt, T. N., Lee, S. I., Jablonski, P. G. Many species have evolved a suite of anti-predator defences, rather than a single defence. These multiple defences may operate in synchrony or separately at different stages of predation sequence to protect the prey. However, empirical documentation on how

Early Duplication of a Single MHC IIB Locus Prior to the Passerine Radiations

Eimes, J. A., Lee, S. I., Townsend, A. K., Jablonski, P. G., Nishiumi, I., Satta, Y. A key characteristic of MHC genes is the persistence of allelic lineages over macroevolutionary periods, often through multiple speciation events. This phenomenon, known as trans-species polymorphism (TSP), is well documented in several major taxonomic groups, but has

Why do animals hide their warning signals? A paradox explained

Scientists have understood quite well why so many poisonous animals have brightly colored bodies - the colors send a message to the predators: " don't eat me, or you'll get sick and die". But why some toxic animals actually hide the warning colors from the predator's view, showing them only at the

Water striders’ jumping on water — understood and imitated after careful observations

Jumping is an antipredatory adaptation of many water strider species to avoid capture by predators that attack from under the water surface. The Korean-Polish team of biologists, Piotr Jablonski, Sang-Im Lee and Jae Hak Son from the Laboratory of Behavioral Ecology and Evolution (Jablonski, Lee and Son) and the Institute of Advanced

A small vortex on the wing makes the elegance of birds’ flight

One mystery of birds' flight is solved! The elegance of birds' flight, their seemingly effortless aerial turns and the softness of their landing, have been envied by many people. From countless observations, it has been known that the birds use a small group of feathers, called "the alula", a thumb-like structure that

Birds ‘weigh’ peanuts and choose heavier ones

Many animals feed on seeds, acorns or nuts. The common feature of these are that they have shells and there is no direct way to know what's inside. How do the animals know how much and what quality of food is hidden inside? A simple solution would be to break the shells,
