Fatal attraction: carnivorous plants roll out the red carpet to lure insects.
We provide the first experimental test of the hypothesis that the coloration of carnivorous plants can act as a signal to lure insects and thus enhance capture rates. An experimental approach was needed to separate effects of the visual appearance of plants from those of traits that may correlate with appearance and also affect capture rates. We compared insect capture rates of pitcher plants w...

Figure 1. Carnivorous plants. When we chew and then swallow meat, we stimulate glands (pancreatic acinar cells) to secrete hydrochloric acid and proteases. Amino acids released into the human stomach by the acidic lytic sap are forwarded to and taken up by the intestine. When compared with the human endocrine system, the Venus flytrap also operates as a mouth, stomach and intestine, all combine...
متن کاملFatal attraction
L ook carefully at a solitary animal and you will find that it is not so alone after all. Animals play host to entire ecosystems that teem with diverse life. Some of the microbes that live on (or in) animals are beneficial to their host. However, these microbes' more sinister brethren, parasites and pathogens, cause damage and disease. Between these two extremes is a class of organisms that, it...
متن کاملFatal attraction: adaptations to prey on native frogs imperil snakes after invasion of toxic toads.
Adaptations that enhance fitness in one situation can become liabilities if circumstances change. In tropical Australia, native snake species are vulnerable to the invasion of toxic cane toads. Death adders (Acanthophis praelongus) are ambush foragers that (i) attract vertebrate prey by caudal luring and (ii) handle anuran prey by killing the frog then waiting until the frog's chemical defences...
متن کاملVisual Attention Driven by Auditory Cues - Selecting Visual Features in Synchronization with Attracting Auditory Events
Human visual attention can be modulated not only by visual stimuli but also by ones from other modalities such as audition. Hence, incorporating auditory information into a human visual attention model would be a key issue for building more sophisticated models. However, the way of integrating multiple pieces of information arising from audio-visual domains still remains a challenging problem. ...
