“…Offspring production by female asexual P. antipodarum is resource limited (Dorgelo et al, 1995;Neiman, 2006), with the implication that lineages that produce sons might produce fewer daughters than lineages that do not produce males. If the drop in daughter production is proportional to the number of sons produced, the 5-10% decrease in daughter production experienced by sonproducing asexual females could influence the outcome of competition amongst asexual lineages.…”

As only females contribute directly to population growth, sexual females investing equally in sons and daughters experience a two-fold cost relative to asexuals producing only daughters. Typically, researchers have focused on benefits of sex that can counter this 'cost of males' and thus explain its predominance. Here, we instead ask whether asexuals might also pay a cost of males by quantifying the rate of son production in 45 experimental populations ('lineages') founded by obligately asexual female Potamopyrgus antipodarum. This New Zealand snail is a powerful model for studying sex because phenotypically similar sexual and asexual forms often coexist, allowing direct comparisons between sexuals and asexuals. After 2 years of culture, 23 of the 45 lineages had produced males, demonstrating that asexual P. antipodarum can make sons. We used maximumlikelihood analysis of a model of male production in which only some lineages can produce males to estimate that B50% of lineages have the ability to produce males and that B5% of the offspring of male-producing lineages are male. Lineages producing males in the first year of the experiment were more likely to make males in the second, suggesting that some asexual lineages might pay a cost of males relative to other asexual lineages. Finally, we used a simple deterministic model of population dynamics to evaluate how male production affects the rate of invasion of an asexual lineage into a sexual population, and found that the estimated rate of male production by asexual P. antipodarum is too low to influence invasion dynamics.

“…However, the levels of arsenic used in the Golding experiments were one to two orders of magnitude greater than those found in geothermal heated waters with naturally occurring high levels of arsenic (Savka 1993). Dorgelo et al (1995) found that elevated levels of cadmium and copper resulted in a decrease in growth rate of approximately 50 % for NZ mudsnails. These findings suggest that NZ mudsnails have metal tolerances similar to those observed for other gastropods (Harman 1974).…”

“…Similar to most gastropods, NZ mudsnails are sensitive to dissolved metals and a range of lethal and sub-lethal effects have been documented (Harman 1974, Moller et al 1994, Dorgelo et al 1995, Golding et al 1997. Golding et al (1997) demonstrated that snails undergo avoidance and immobility behavior in response to elevated levels of dissolved arsenic.…”

“…This material will hereafter be referred to as detritus, which is a common food source for detritivorous chironomids like C. riparius (Rasmussen 1984). Therefore, concentrations of metals in detrital particles will be a valuable characterisation of the exposure of detritivores, like chironomids, to the overall metal pollution in sediments (Simkiss 1990;Dorgelo et al 1995).…”
