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

Water striders adjust leg movement speed to optimize takeoff velocity for their morphology

Yang, E., Son, J. H., Jablonski, P. G., & Kim, H. Y. Water striders are water-walking insects that can jump upwards from the water surface. Quick jumps allow striders to avoid sudden dangers such as predators’ attacks, and therefore their jumping is expected to be shaped by natural selection for optimal performance. Related

Evolution of plumage coloration in the crow family (Corvidae) with a focus on the color-producing microstructures in the feathers: a comparison of eight species

Lee, S. I., Kim, M., Choe, J. C., & Jablonski, P. G. The alula is a small structure located at the joint between the hand-wing and arm-wing of birds and is known to be used in slow flight with high angles of attack such as landing. It is assumed to function similarly to

Antarcitc skuas recognize individual humans

Lee, W. Y., Han, Y. D., Jablonski, P. G., Jung, J. W., & Kim, J. H. Recent findings report that wild animals can recognize individual humans. To explain how the animals distinguish humans, two hypotheses are proposed. The high cognitive abilities hypothesis implies that pre-existing high intelligence enabled animals to acquire such abilities.

Predators induce conditions for size-dependent alternative reproductive tactics in a water strider male

Han, C. S., & Jablonski, P. G. Alternative reproductive tactics (ARTs) are commonly associated with differences in morphological, physiological and behavioural traits. The morphological differences can be associated with differences between ARTs in effectiveness of sexual display but the relationship has rarely been documented. We tested it using the Asian water strider Gerris gracilicornis
