Ballooning is a behavior in which spiders and some other invertebrates use airborne dispersal to move between locations. [ 4 ] [ 5 ] A spider (usually limited to individuals of a small species), or spiderling after hatching, [ 6 ] will climb as high as it can, stand on raised legs with its abdomen pointed upward ("tiptoeing"), [ 7 ] and then ...
Spider ballooning structures. Black, thick points represent the spider's body. Black lines represent ballooning threads. [63] Many small animals, mainly arthropods (such as insects and spiders), are also carried upwards into the atmosphere by air currents and may be found floating several thousand feet up.
Ballooning is a term used for the mechanical kiting [16] [17] that many spiders, especially small species such as Erigone atra, [18] as well as certain mites and some caterpillars use to disperse through the air. Some spiders have been detected in atmospheric data balloons collecting air samples at slightly less than 5 km (16,000 ft) above sea ...
The heterosphere is the layer of an atmosphere where gases are separated out by molecular diffusion with increasing altitude such that lighter species become more abundant relative to heavier species. The heavier molecules and atoms tend to be present in the lower layers of the heterosphere while the lighter ones are present higher up.
The homosphere is the layer of an atmosphere where the bulk gases are homogeneously mixed due to turbulent mixing or eddy diffusion. The bulk composition of the air is mostly uniform so the concentrations of molecules are the same throughout the homosphere. The top of the homosphere is called the homopause, also known as the turbopause.
