The term glomerulonephritis (GN) covers a group of conditions in which there is injury in the glomerulus, the filtering unit of the kidney. This can occur either as a primary glomerular disease, or secondary to drugs, infections or tumours (see Secondary Glomerular Disease, pp 464â466 of this issue).
As insects are spiders' main prey, it is likely that they would impose strong selectional forces on the foraging behavior of spiders. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them.
Some species hide in vegetation or leaf litter, while others dig tunnels or use other animalsâ tunnels. Some wolf spiders hunt in a set territory and return to a specific place to feed, while others wander nomadically with no territory or home. Wolf spiders eat mostly ground-dwelling insects and other spiders. Especially large females may eat small vertebrates, according to BioKids. Some species chase down and grab their prey, while others wait for it to walk by and ambush it. Wolf spiders often jump on their prey, hold it between their legs and roll over on their backs, trapping their prey with their limbs before biting it.
