Are web stabilimenta attractive to praying mantids?
Certain species of orb-weavers add extra silk structures, termed a stabilimentum or web decoration, to their webs. In the genus Argiope stabilimenta are silken structures of densely woven zig-zag ribbons. The adaptive value of these stabilimenta is still unclear and controversially discussed. In the course of time, many functional hypotheses have been proposed for silk stabilimenta. Because of ...
متن کاملMismatch repair: The praying hands of fidelity
High-resolution crystal structures have recently been solved for the mismatch binding protein MutS of Escherichia coli and its Thermus aquaticus homologue; they show how these factors recognise such structurally diverse substrates as base-base mismatches and insertion/deletion loops.
متن کاملBinocular Spatial Localization in the Praying Mantis
The way in which mantids localize the direction and the distance of their prey has been analysed, to clarify the importance of binocular interactions. The results suggest the following major points: 1. Binocular interactions coordinate monocular directional information, such that the direction in which a mantid fixates its prey is intermediate between the image directions in the two eyes (Figs ...
متن کاملLeg Design for a Praying Mantis Robot
The praying mantis uses its front legs for locomotion, prey capture and feeding. Inspired by this dexterity, we began designing a hexapod robot that could use its front legs for both locomotion and manipulation. Our current work focuses on the middle and back legs of the robot. We designed a five degree of freedom leg, using a gimbal to form three intersecting axes of rotation at the hip to imi...
متن کاملMismatch repair: praying for genome stability
For the reader who believes that only computers can faithfully duplicate gigabits of information, some insights into his or her own biology will be revealing. Just as he or she reads this Primer, billions of his or her cells prepare for division by replicating the six billion or so DNA nucleotides of their diploid genomes, each cell typically making not more than a single mistake. This extraord...
