We estimated annual secondary production by copepod species on the Emerald Bank, Scotian Shelf, for the first time. We tentatively ranked copepod species in order of importance based on production to biomass (P/B) ratios calculated from adult body mass using an empirical relationship. The significance of assessing species in terms of production rather than population biomass is demonstrated. The mean estimate of total copepod production (530 kJ∙m−2) is in good agreement with previous estimates of secondary production on the Scotian Shelf.

The Mean

Reproduction in Pseudocheirus peregrinus viverrinus in coastal teatree woodland on Flinders Island was seasonal. The main birth season was from May to August. The mean duration of lactation was 29 weeks. The duration of lactation for multiparous females that bred twice in a year was significantly shorter than that of multiparous single breeders. In general the young left the pouch during early spring and were fully weaned by the early summer months. In contrast to populations of P. peregrinus inhabiting similar woodland in Victoria only a few multiparous females (6-9%) gave birth to a second litter in the springlsummer months on Flinders Island. The mean litter size (1.84) and annual fecundity of the population (1.91 offspring per female) were lower than those reported for three populations of Pseudocheirus peregrinus in Victoria. It is suggested that the low occurrence of spring/summer births and low fecundity of P. p. viverrinus on Flinders Island may be related to the age and nutrient status of their coastal teatree forest habitat. The body mass of P. p. viverrinus was higher than previously recorded for P. peregrinus. The adult body mass of females ranged from 948 to 1082 g. Adults showed seasonal variation in body mass with most females losing weight during the late spring and summer months coincident with late lactation. It is proposed that the larger body size of P. p. viverrinus on Flinders Island is a result of release from predation pressure and/or interspecific competition.

Abstract. From 1992 to 1997, the WINDII interferometer on board the UARS satellite acquired a large set of thermospheric data from the O(1D) and O(1S) airglows. We report here for the first time on daytime O(1D) Doppler temperatures obtained with version 5.11 of the WINDII data processing software. Using a statistical analysis of the temperatures independently measured by the two WINDII fields of view, we estimate that the temperature variations larger than 40 K can be considered as geophysical. Comparisons of WINDII temperatures measured during magnetically quiet days with temperatures obtained by the MSIS-90 and DTM-94 thermospheric models show a 100 K bias. We demonstrate, however, that the modeled temperature variations represent very well the mean temperature variation observed by WINDII over 4 years. We also show that the observed latitudinal/local time variation is in very good agreement with the two empirical models. Finally, the temperature variations during a magnetically disturbed day are found to be qualitatively well represented in form by the models, but largely underestimated. The presence of non-thermal atoms and instrument related issues are discussed as possible explanations for the 100 K bias between the WINDII Doppler temperatures and the empirical models.Key words.

We tested if there was a difference in mass-specific excretion rate between two genetically size-divergent brook trout (Salvelinus fontinalis) populations that can be accounted for by genetic/maternal factors. We conducted laboratory-based common garden experimentation using F1 generation fish, with five to seven families per population at two ages (0.5 year juveniles and 1.5 years adults). We found that genetic/maternal differences in excretion rate on a per gram basis coevolve with genetic divergence in adult body mass between the populations. However, this coevolution has also resulted in no net difference in excretion rate between populations when differences in adult body mass were accounted for. Uncertainty in census estimates and variation in body mass distributions created substantial variation in extrapolated whole-population excretion estimates. No other studies to our knowledge have tested for genetic/maternal divergence in excretion rate between genetically size-divergent fish populations. Genetically based population divergence in body mass, energy allocation in reproduction, and mass-specific excretion rate in the brook trout was likely a result of selection associated with differences in the availability of overwintering habitat between streams.
