Do Parents Adjust Predator Warning Calls to the Age of Nestlings: Expriments on Parus minor?

Ha, J. M., Yang, E. J., Lee, K. S., Lee, S. I., Jablonski, P. G. The Oriental tits Parus minor is known for their specialized ‘snake call’ to make their nestlings jump out from the nest box when the snake is approaching (Suzuki 2011). Hence, the function of “snake call” is to induce jumping

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

Adaptations of Grasshoppers to Jump From Flexible Substrates

Jung, Y. J., Baek, M. J., Kim, Y. W, Yang, E. J., Kim, H. Y., Klassen, M. J., Moeller, J. M., Kim, H. K., Lee, S. I., Jablonski, P. G. Grasshoppers have become model organisms to understand the biomechanics of jumps. However, surprisingly little is known about their adaptations to the natural substrates

Can Water Striders Adjust Their Jumping Performance to Their Body Mass Through Individual Experience

Baek, M. Jung., Lawin, K. M., Codden, C. J., Lim, H. K., Lee, S. I., Jablonski, P. G. In response to predators’ attacks from under the water surface, water striders use sudden upward escape-jumps to escape danger. Water striders perform as if they “knew” how to move their legs for maximization of their

Detection of Antibiotic-Resistant Bacteria from the Feces of Eurasian Magpie pica pica

Kim, Y. W., Jablonski, P. G., Choe, J. C., Lee, S. I. Drug resistance in bacteria is one of the most important issues in the world. Previous studies show that antibiotic-resistant bacteria can be carried by populations of wild animals inhabiting urban environment or human settlements. In this study, we examined the presence

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

Flucutating sexual selection and the evolution of a courtship strategy

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

Empirical evidence for large X-effects in animals with undifferentiated sex chromosomes

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
