“…Although prey sampling may provide more accurate assessment of patch quality, acquiring that information is often more costly in terms of lost foraging time (Morse 1993). Because S. ocreata, like other spiders, may have long time intervals between prey capture (Miyashita 1969;Greenstone 1980), reliance on sampling information (prey capture rates or gut fullness alone) may result in considerable time lost in prey-poor patches. Therefore, it would be advantageous to make decisions regarding duration of patch visits in advance, based on perceived resource value (i.e.…”

“…Running on the treadmill under steady state V CO ∑ caused factorial scopes of 10 in P. lugubris and of 18 in M. muscosa (resting rates from Schmitz, 2004). For other wolf and jumping spiders and also for tarantulas, aerobic scopes during running were reported to be normally 3-10 (Miyashita, 1969;Seymour and Vinegar, 1973;Ford, 1977;Humphreys, 1977;Herreid, 1981;Prestwich, 1983b;Shillington and Peterson, 2002). All reported values higher than 6-8 are based on measurements of V CO ∑, indicating considerable anaerobic proportions.…”

The CO 2 release of the well-tracheated jumping spider, Marpissa muscosa, and the poorly tracheated, Pardosa lugubris, was tested while animals were running on a treadmill at three different speeds and under a selective elimination of lungs or tracheae. Thus, the influence of a well-developed tracheal system on the metabolism during physical exercise was examined. The CO 2 release in intact animals increased with the running speed in both species. The costs of transport (COT) running at the maximal sustainable speed were nearly twice as big in M. muscosa as in P. lugubris. Elimination of one lung by sealing resulted in reduced COT and running times, and increasing anaerobic proportions in metabolism. Effects were greater in P. lugubris than in M. muscosa, indicating that tracheae compensate partly for the lacking lung capacity. Sealing of the tracheae in M. muscosa reduced the COT and the running times only at the highest speed. Results indicate that tracheae in M. muscosa support the aerobic metabolism only at the most intense physical exercise. At low and medium activity, tracheae may play their main role in the local supply of organs that are not involved in running activity.

“…The results show that Desis marina has respiration rates which are lower than those reported for other species (Ito 1964;Reichle 1968;Miyashita 1969;Anderson 1970;van Hook 1971;Dondale & Lengendre 1971;Moeur & Erickson 1972;Myrcha & Steigwillo-Laudanska 1973;Humphreys 1975;McQueen et al 1979). In Geolycosa domifex (Hancock) (McQueen et al 1979) the respiration-regression line at 18°C was log,cft = -0.29 + 0.66 log W (where R = IlQ h-' of CO 2 ), which gives respiration rates that are 1.73 (10 mg spider) to 2.04 (100 mg spider) times higher than the oxygen respiration rates for D. marina.…”

Respiration experiments involving the intertidal spider Desis marina (Hector) yielded a respiration ( Il~ h-' ) -weight (mg) relationship of 10g,oR = 0.6110g1OW -0.61 at 17SC; which is much lower ( < 50%) than the rates obtained for terrestrial spiders. D. marina was also able to survive until oxygen partial pressures fell to 18-24 mmHg (12% of ambient levels). These 2 features help explain how D. marina are able to withstand long periods of submergence in bull kelp holdfasts on the shore. Calculations and experiments involving air spaces which did not contain spiders both suggested that the 'physical gill effect' should provide enough oxygen to ensure > 100 days underwater survival for even the largest animals. However, survival and respiration experiments suggested that the spiders 'conditioned' their environment so that the physical gill effect was reduced to providing only 3 -10% (depending upon weight) of the required oxygen.
