“…The Qlo values calculated in this study were: N g a v i s 2.18 (males) and 1.72 (females); N.philippi 2.12 (males) and 2.15 (females). These are slightly lower values than those reported for other carabids: 2.90-3.37 for Nebria brevicollis (Manga, 1972) and 2.3-3.0 for Pterostichus coerulescerts L. (Mols, 1988); but are in close agreement with the Van?…”

“…Very little has been published on the respiratory metabolism of carabids. The studies on two European species, Pterostichus coerulescerzs (Mols, 1988) and Nebria brevicollis (Manga, 1972) provide recent information and summarize the relevant literature. Most researchers have found or assumed that there is no difference between the respiration rates of male and female carabids (Mols, 1988).…”

The respiration rates of Notonomus gravis (Chaudoir) and N.philippi (Newman) (Coleoptera: Carabidae) were measured at temperatures between 10°C and 45°C. Mature males of both species had higher respiration rates than mature females. There was no difference between the rates of teneral male and female beetles at 30°C. The difference in respiration rates between the sexes is attributed to the maternal behaviour, and decreased surface activity, of mature females.

“…The high net production efficiency (Pg/A = 60.3%, P 8 + PeviA = 66%) in C. cornutus may result from its ability to conserve energy by metabolic compensation to seasonal temperatures, which as discussed above, may be unique among insects. Production efficiency for other insects are 5-25% below that for hellgrammites (e.g., McDiffett 1970, Lawton 197Ia, Bailey and Riegert 1972, Heiman and Knight 1975, Randolph et al 1975 Total Pev by C. cornutus (13.4%) falls within the range (2.7-14.7%) reported for other insects (e.g., Dutton 1968, McDiffett 1970, Lawton 1971a, Manga 1972, Bailey and Riegert 1972, Randolph et al 1975).…”

Ecological Society of America is collaborating with JSTOR to digitize, preserve and extend access to Ecology.Abstract. Rates and energies of consumption (C), egestion (F), assimilation (A), respiration (R), growth (Pg), production of exuviae (P,,), and production of egg masses (Pr) with associated efficiencies, and effects of seasonal temperature, weight and life-history stage upon them were examined for a typical individual and cohort of Corydalus cornutus (L.) from a stream in north-central Texas. Dobson flies are univoltine with 11 larval instars. Emergence, oviposition, and hatching occurred from late May into August. The typical dobson fly hatched in mid-June, grew rapidly until November, and again in March, reaching adult size prior to pupation in early June. Adult females fed to provide energy to yolk eggs, produce egg cases and for maintenance during their week of reproductive activities.Metabolic compensation enabled larval dobson flies to maintain fairly constant rates of R during winter (6.07 J g-~ h-', 5-15°C) and summer (16.15 J g-~ h-1, 20-30°C); with a seasonal acclimatization threshold occurring between 15-20°C. Metabolic constancy is adaptive and probably contributed to high ratios of P/R (1.94) and P/A (66%) for individual larvae. Rates of C, F, A and R, but not assimilation efficiency (AE = A/C x 100), were influenced by temperature and size.The energy budget for a typical dobson fly during the 47 wk as a larva was: C = 17,435, A 14,401, F = 3,033, Pg = 8,682. P,v = 828 and R = 4,892 J. Embryos respired 0.45 J/wk, prepupae 1,494 J/wk, male pupae 2,130 J/wk, female pupae 1,900 J/wk, male adults 2,615 J/wk and female adults 3,075 J/wk. Prepupal and pupal exuviae were 602 J and 502 J respectively. The average adult female's minimal reproductive effort was 2,791 J for eggs and 774 J for egg cases, 54 and 100% of her A and P respectively, and 17% of her life-history A. Annual energetics of the larval population were; C = 165,343, A = 136,574, F = 28,769, Pg 54,610, P,(V = 15,096, Pr = 1,502-1,711 and R = 66,869 J m-2.data indicate a 1-yr cycle in north-central Texas. Typically, final-instar larvae leave the stream to pupate in the soil, under rocks or in rotting logs several metres from the stream. The first pupal stage (prepupa) retains the appearance of the larva, but soon molts to a cream-colored, exarate pupa. After a week or so, depending upon latitude, the nocturnal adult emerges. Mating occurs almost immediately and females deposit egg masses within several days on objects hanging directly over streams near suitable riffle habitats. Eggs normally hatch within 2 wk and the first-instar larvae fall into the stream. The study area Population estimates were taken...

“…Dispersal within the grid seemed to be random. Several authors (Nelson 1970, Manga 1972, Ericson 1977 have used marking methods (branding and scraping of the elytra) which are similar to the method employed in this study. They concluded that such marking had no effect on vitality or survival.…”
