The Effects of Condition and Sex on Leg Regeneration in the Wolf Spider Rabidosa punctulata
نویسنده
چکیده
The act of autotomy and subsequent limb regeneration occurs fairly frequently in wolf spiders. Limb regeneration however can have its tradeoffs, causing a decrease in mass and prolonged development; this process can sometimes result in a limb that is shorter, misshaped, and discolored. Differential uses across the legs may influence how spiders invest in their regeneration. In both sexes, the forelimbs are often used to capture prey, while in males the forelimbs also are used in courtship to attract a mate. We autotomized spiders and exposed them to different diets, to examine the effects on the limb’s length, the spiders mass and the investment into leg regeneration made between genders. We found that males invest more into regrowing their forelegs despite their conditions, while females invested equally in regrowing both their legs and that across both gender and diet significantly affected the length of the regenerated limb.

Octopamine levels relate to male mating tactic expression in the wolf spider <i>Rabidosa punctulata</i>
In the wolf spider Rabidosa punctulata, upon encountering a female, males use one of two distinct strategies: (1) they court the female in an attempt to elicit a mating, or (2) they engage in a direct-mount tactic that involves extensive grappling with the female until a mating is achieved. The latter tactic appears more sexually aggressive, and both tactics come with the risk of being cannibal...

We evaluated the potential for emergent nonlinear effects of multiple predators on mortality of a shared prey species by conducting experiments in cages in an old field. We examined interactions among three spider predators, Pisaurina mira, Phidippus rimator, and Rabidosa rabida, and a grasshopper prey Melanoplusfemurrubrum. The predators have disparate hunting behaviors and are located in diff...

Objective: People with Anterior Cruciate Ligament (ACL) reconstruction need to have almost automatic postural control to focus on their athletic skills. Continuous cognitive task is a method for removing attention from postural control. The effects of continuous cognitive task on postural control of people with ACL reconstruction has been assessed by laboratory tools; however, its effect using ...
