A murder in the magpie’s nest

Finding their young dead in the nest is not uncommon for bird mothers. In many bird species some of the nestlings die before they leave the nest. This is known as "brood reduction", a common form of infanticide that the parents are to blame ... [Read More]

Magpies recognise and ‘scold’ individual humans

During a routine nest-monitoring study a research team in South Korea discovered that the birds recognised an individual that had previously climbed up to and disturbed their nests ... [Read More]

I know you, bad guy!

Most people who have had the experience of having pet animals in their houses have the gut feeling that the animals can "recognize" us. They seem to recognize our faces, our voices and our smell. One way or another, they respond to us differently from other people ... [Read More]

Molecular methods are not sufficient in systematics and evolution

Modern evolutionary systematists often use molecular methods, such like mitochondrial DNA analysis, to differentiate between species and subspecies. However, current research indicates that the picture painted by these methods may be incomplete, and only a creative combination of classical field-based ecology, museum-based systematics and DNA-based phylogenetics, can lead to right conclusions. In

Cold-blooded mothers: Magpie parents seem to induce mortality of ‘unwanted’ chicks

Human parents often pay more attention to a few favored children among all of their offspring. It has already been known that birds do it too, and it may result in some baby birds dying in the nests. According to the recent discoveries published in Journal of Avian Biology, the top journal

Hidden genitalia in female water striders makes males ‘sing’

In a study published in the open-access, peer-reviewed journal PLoS ONE June 10, Chang Seok Han and Piotr Jablonski at Seoul National University, Korea, report that by evolving a morphological shield to protect their genitalia from males' forceful copulatory attempts, females of an Asian species of water strider seem to "win" the

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
