“…The evacuation rate of sand goby and common goby was calculated according to Andersen (1984): R ¼ 7:385 Â L À0:832 Â exp½0:0639(t À 20) where L is the total length of the goby in mm and t the ambient water temperature (8C). Santulli et al (1993) determined the gastric evacuation of 0-group bass resulting in a rate of 0.028% wet body weight h 71 at 158C. Koed (2001) described the gastric evacuation of pikeperch as R ¼ 0:000173 Â exp(0:15t) Â L 1:15 Â W 0:5 24 where L is the total length in cm and t the water temperature in 8C.…”

Seasonal changes in the diet composition and trophic niche overlap were examined for the dominant members of the fish assemblage of the turbid low-salinity zone of the Scheldt estuary (Belgium). Samples of fish were taken in the cooling water of a power plant. juveniles of eight species dominated the fish assemblage: two goby species, herring, sprat, bass, flounder, eel and pikeperch. Together, they had preyed upon 31 different prey taxa. Calanoid copepods and hyperbenthic mysids were the most important prey items with macrobenthic invertebrates being largely ignored. Pair-wise comparisons of trophic niche overlap showed that, in general, niche overlap between individuals of the same species was significantly higher than overlap between individuals from different species, suggesting that the available food resources were partitioned. The total annual prey consumption by the dominant fish species was estimated at 610 mg ash-free dry weight m(-3)

“…In Year 1, females were captured in the spring and were given access to either 3 h or 10 h of radiant heat per day (hereafter, "basking regime") for 4-5 months over the summer. These treatment levels were designed to Santulli et al 1993), females in the 10-h basking regime were predicted to assimilate more energy than females in the 3-h treatment. In addition, gravid females accelerate embryogenesis by spending longer periods at preferred basking temperatures (-320C), not by selecting higher body temperatures (Schwarzkopf and Shine 1991).…”

Ecological Society of America is collaborating with JSTOR to digitize, preserve and extend access to Ecology.Abstract. When animals reproduce, does energy for the brood come from stored reserves (from food eaten months or years before), or from food eaten during the current reproductive season? Variation in the duration of energy storage prior to reproduction is an important, but little-studied, axis of life history variation. We experimentally manipulated the availability of resources to females of a long-lived viviparous lizard (Eulamprus tympanum. Scincidae) in the first year of a two-year study to assess the relative importance of current food intake vs. stored reserves as sources of energy for breeding. Females given greater access to high temperatures (and hence, to resources) in the laboratory amassed larger caudal energy stores than did females with lesser opportunities. Energy intake during gestation slightly influenced offspring size, but the magnitude of energy stores prior to ovulation had a more dramatic effect: females with larger caudal energy stores produced much larger litters in the following year. Growth rates of females were unaffected by basking treatments or by reproduction in either year, but females that reproduced in the second year showed a large concomitant decrease in caudal energy stores compared to females that did not reproduce, indicating a large energetic cost of reproduction. Hence, reproductive output within this species can be influenced by resource availability over 12 months prior to reproduction, and simple comparisons of reproductive output with current resource availability may fail to detect the ways in which phenotypically plastic life history traits are influenced by environmental features. In addition to an appropriate temporal framework, models of resource allocation should also incorporate the possible roles of physiological and morphological constraints (e.g., maternal inability, in some species, to modify postovulation reproductive expenditure) and trade-offs with other life history currencies (e.g., decrements in maternal survival due to high relative clutch masses). The time lag between resource acquisition and expenditure may have significant consequences for a population's demographic response to shifts in resource availability or predation pressure (via tail autotomy). Finally, this study illustrates the way in which thermal aspects of the environment can influence life history phenotypes in ectothermic vertebrates with long-term energy stores.

“…Both temperature (Jobling et al, 1977;Miegel et al, 2010;Santulli et al, 1993) and animal size (Bassompierre et al, 1998;Heyraud, 1979;Jobling et al, 1977) influence the GIE time and the gastric evacuation time and rate of other aquatic animals. The trend common to these studies is that decreasing water temperatures and increasing animal sizes leads to an increased GIE times.…”
