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

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.

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

Han, C. S., Brooks, R. C., & Jablonski, P. G. Fluctuating sexual selection caused by environmental heterogeneity can maintain variation in sexual signals. Sexual selection can also shape correlations among behavioral traits (behavioral syndromes) when certain behavioral combinations enjoy greater fitness than other combinations (i.e., under correlational sexual selection). Here, we tested the

Dufresnes, C., Majtyka, T., Baird, S.J., Gerchen, J.F., Borzée, A., Savary, R., Ogielska, M., Perrin, N. and Stöck, M. Reproductive isolation is crucial for the process of speciation to progress. Sex chromosomes have been assigned a key role in driving reproductive isolation but empirical evidence from natural population processes has been restricted to

Lee, S. I., Kim, J., Park, H., Jabłoński, P. G., & Choi, H. 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

Koh, J.S., Yang, E., Jung, G.P., Jung, S.P., Son, J.H., Lee, S.I., Jablonski, P.G., Wood, R.J., Kim, H.Y. and Cho, K.J. Jumping on water is a unique locomotion mode found in semi-aquatic arthropods, such as water striders. To reproduce this feat in a surface tension–dominant jumping robot, we elucidated the hydrodynamics involved and

Jablonski, P. G., Fuszara, E., Fuszara, M., Jeong, C., & Lee, W. Y. In contrast to extensive research on optimal foraging in birds, the proximate mechanisms by which birds estimate the properties of nuts or seeds have not been well studied. Using slow-motion video-recording and experiments with modified peanuts presented to birds in

Kang, C., Stevens, M., Moon, J. Y., Lee, S. I., & Jablonski, P. G. Camouflage can be attained via mechanisms such as background matching (resembling the general background) and disruptive coloration (hindering the detection of an animal’s outline). However, despite much conceptual work with artificial stimuli there have to date been few studies

Son, J. H., Han, C. S., & Jablonski, P. G. Water striders use ripple signals in aggressive interactions between individuals for access to food. We asked whether water striders produce ripple signals more frequently when they are hungrier and when the value of food resources is higher. We also asked if and how
