“…In the only other study addressing stoichiometric effects on life history traits of an invasive animal, the invasion success of Daphnia lumholtzi is attributed to higher resting egg production compared with native daphniids (Acharya et al 2006). The authors suggested that the unusually high % RNA measured in D. lumholtzi compared to native Daphnia sp.…”

“…The authors suggested that the unusually high % RNA measured in D. lumholtzi compared to native Daphnia sp. allowed D. lumholtzi to allocate more to resting egg production capacity under deteriorating environmental conditions (Acharya et al 2006). The shift in allocation from growth to production of embryos between weeks 4 and 8 for mudsnails in the IP and LOP treatments may reflect a similar strategy when resource quality is low.…”

“…Therefore relatively fast-growing, P-rich consumers can be more susceptible to P limitation of food resources (Sterner and Elser 2002;Frost et al 2006). However, few studies have also addressed the effects of food C:P ratios on reproduction, the exceptions focusing on freshwater zooplankton (Urabe and Sterner 2001;Acharya et al 2006). In this study we show how both growth and reproduction of the invasive New Zealand mudsnail, Potamopyrgus antipodarum, respond to stoichiometrically imbalanced food.…”

Understanding the mechanisms that species use to succeed in new environments is vital to predicting the extent of invasive species impacts. Food quality is potentially important because it can affect population dynamics by affecting life history traits. The New Zealand mudsnail, Potamopyrgus antipodarum, is a worldwide invader. We examined how mudsnail growth rate and fecundity responded to the C:P ratio of algal food in laboratory conditions. Mudsnails fed low-P algae (C:P 1,119) grew more slowly, matured later, produced smaller offspring, and grew to a smaller adult size than snails reared on algae with high levels of P. A relatively small increase in algal C:P (203-270) significantly increased mudsnail age at maturity. We suggest that the relatively high body P requirements of mudsnails make them susceptible to allocation trade-offs between growth and reproduction under P-limited conditions. The elemental composition of algae varies greatly in nature, and over half of the rock biofilms in streams surveyed within the introduced range of mudsnails in the Greater Yellowstone Area had C:P ratios above which could potentially pose P limitation of life history traits. High growth rate and fecundity are common traits of many species that become invasive and are also associated with high-P demands. Therefore, fast-growing consumers with high P demands, such as mudsnails, are potentially more sensitive to P limitation suggesting that limitation of growth and reproduction by food quality is an important factor in understanding the resource demands of invasive species.

“…The fertilized ephippium is then released into the water column to await hatching cues. A recent study by Acharya et al (2006) showed that D. lumholtzi produced ten times more ephippia than D. pulicaria and D. magna under similar food conditions. Also, D. lumholtzi had relatively higher body %RNA than the other two species.…”

Daphnia lumholtzi has been very successful in colonizing North America since its appearance in Texas in 1990. Although previous studies have sought to link its success as an invasive species with various aspects of its population biology, there is little experimental data linking the invasion success of D. lumholtzi with its autecology, specifically its reproduction strategy. In this study we sought to link food quality and quantity to diapause in D. lumholtzi through a variation in phosphorus (P) content of algae, food quantity, and light level. We also assessed the effect of Daphnia peak population densities on reproductive rates and production of resting eggs. We found that when food is abundant, per capita ephippia production may be limited by P, but under food limitation conditions, there is no significant effect of food quality on ephippia production. Our results suggest that a combination of food quality/quantity and population density may work together to induce the production of resting eggs in this invasive species.

“…Ability of organisms to change their nutrient stoichiometry according to environmental conditions would be vital for their physiological fitness and invasion success (González et al, 2010). Current knowledge has shown that adaptive changes in stoichiometric traits (e.g., varying tissue nutrient content and growth rate) confer an adaptive advantage (Acharya et al, 2006;González et al, 2010;Jeyasingh et al, 2009). Recent meta-analyses indicate that invasive species are often successful in both low-and high-nutrient environments.…”
