Bimodal breathing in jumping spiders
double respiratory system consisting of book lungs and tube tracheae. The book lungs are the most important for gas exchange in many species and cope alone with the oxygen demands. The tracheae are often only poorly developed and are presumed to be of little importance in overall gas exchange (Anderson, 1970; Anderson and Prestwich, 1982; Strazny and Perry, 1984). In contrast, several species, ...
متن کاملA tephritid fly mimics the territorial displays of its jumping spider predators.
The tephritid fly Zonosemata vittigera (Coquillett) has a leg-like pattern on its wings and a wing-waving display that together mimic the agonistic territorial displays of jumping spiders (Salticidae). Zonosemata flies initiate this display when stalked by jumping spiders, causing the spiders to display back and retreat. Wing transplant experiments showed that both the wing pattern and wing-wav...
متن کاملSexual selection driving diversification in jumping spiders.
Theory predicts that speciation rates should be accelerated in organisms undergoing sexual selection. In systems involving female choice, sexual selection acts directly on traits that may be important in prezygotic reproductive isolation, potentially fostering rapid divergence of such traits among allopatric populations. Despite the appeal of this concept, it has proven difficult to document. W...
متن کاملNeurobiology: Jumping Spiders Getting On Board
A new technique has overcome decades of failure to allow, for the first time, electrophysiological access to the brains of jumping spiders, a group of animals renowned for generating highly complex, seemingly vertebrate-like behavior from their tiny arthropod brains.
متن کاملListen up - jumping spiders can hear airborne sounds.
Jumping spiders (Salticidae) are renowned dancers, but until recently, the music of their courtship was thought to fall on deaf ears. No one had heard of spiders being able to perceive sounds until a recent serendipitous finding published in Current Biology by Ronald Hoy and colleagues from Cornell University, USA. Having previously shown that the spiders rely heavily on vision as they strut th...
