“…Production, P (g DM m -2 y -1 ), is thus estimated by multiplying a literature P/B by the mean biomass, B (g DM m -2 ). We compiled P/B values from the literature for lentic, north-temperate zoobenthos (Neess and Dugdale 1959;Potter and Learner 1974;Momot and Gowing 1977;Waters 1977;Strayer et al 1981;Lafont 1987;Plante 1987;Lindegaard 1992;Phillips 1997;Eleutheriadis andLazaridou-Dimitriadou 2001, Karatayev et al unpublished, Babler et al 2008). Some of these sources are compilations of literature P/B values and we were careful to not include the same data more than once.…”

Estimating benthic invertebrate production in lakes: a comparison of methods and scaling from individual taxa to the whole-lake level

Studies of aquatic invertebrate production have been primarily conducted at the level of individual taxa or populations. Advancing our understanding of the functioning and energy flow in aquatic ecosystems necessitates scaling-up to community and whole-lake levels, as well as integrating across benthic and pelagic habitats and across multiple trophic levels. In this paper, we compare a suite of non-cohort based methods for estimating benthic invertebrate production at subpopulation, habitat, and whole-lake levels for Sparkling Lake, WI, USA. Estimates of the overall mean benthic invertebrate production (i.e. wholelake level) ranged from 1.9 to 5.0 g DM m -2 y -1 , depending on the method. Production estimates varied widely among depths and habitats, and there was general qualitative agreement among methods with regards to differences in production among habitats. However, there were also consistent and systematic differences among methods. The size-frequency method gave the highest, while the regression model of Banse and Mosher (Ecol Monogr 50:355-379, 1980) gave the lowest production estimates. The regression model of Plante and Downing (Can J Fish Aquat Sci 46:1489-1498, 1989) had the lowest average coefficients of variation at habitat (CV = 0.17) and whole-lake (CV = 0.08) levels. At the habitat level, variance in production estimates decreased with sampling effort, with little improvement after 10-15 samples. Our study shows how different production estimates can be generated from the same field data, though aggregating estimates up to the whole-lake level does produce an averaging effect that tends to reduce variance.

Secondary production and diet of an invasive snail in freshwater wetlands: implications for resource utilization and competition

et al. 2009

Invasive species can monopolize resources and thus dominate ecosystem production. In this study we estimated secondary production and diet of four populations of Pomacea canaliculata, a freshwater invasive snail, in wetlands (abandoned paddy, oxbow pond, drainage channel, and river meander) in monsoonal Hong Kong (lat. 22°N). Apple snail secondary production (ash-free dry mass [AFDM]) ranged from 165.9 to 233.3 g m -2 year -1 , and varied between seasons. Production was lower during the cool dry northeast monsoon, when water temperatures might have limited growth, but fast growth and recruitment of multiple cohorts were possible throughout much (7-10 months) of the year and especially during the warm, wet southwest monsoon. The diet, as revealed by stomach-content analysis, consisted mainly of detritus and macrophytes, and was broadly consistent among habitats despite considerable variation in the composition and cover of aquatic plants. Apple snail annual production was[10 times greater than production estimates for other benthic macroinvertebrates in Hong Kong (range 0.004-15 g AFDM m -2 year -1 , n = 29). Furthermore, annual production estimates for three apple snail populations (i.e.[230 g AFDM m -2 year -1 ) were greater than published estimates for any other freshwater snails (range 0.002-194 g AFDM m -2 year -1 , n = 33), regardless of climatic regime or habitat type. High production by P. canaliculata in Hong Kong was attributable to the topical climate (annual mean *24°C), permitting rapid growth and repeated reproduction, together with dietary flexibility including an ability to consume a range of macrophytes. If invasive P. canaliculata can monopolize food resources, its high productivity indicates potential for competition with other macroinvertebrate primary consumers. Manipulative experiments will be needed to quantify these impacts on biodiversity and ecosystem function in wetlands, combined with management strategies to prevent further range extension by P. canaliculata.

“…The pattern of growth and development of the hatchlings over time under laboratory conditions paralleled the Saumarez Road swamp collections. Eleutheriadis and Lazaridou-Dimitriadou (2001) found in Bithynia graeca that maturation of gonads corresponded to external morphometric changes in growth of the shell. A similar conclusion can be drawn for G. vertiginosa, as demonstrated by the size/time ratios described in Fig.…”

Aspects of the reproduction and population structure of Gabbia vertiginosa (Bithyniidae) in the New England Tablelands, New South Wales, Australia, are described. The pattern of embryo growth from encapsulation in the pallial oviduct, deposition of fully formed embryonic snails in the habitat, to sexual maturity in the adult snail are examined. A three-year population study has shown the reproductive period of G. vertiginosa to commence in December and end in June/July with the possibility of three reproductive events per season.
