“…The growth rate of poikilothermic animals depends on the metabolic rate, which rises with an increase in temperature but the net reproductive rate should be stable at different temperatures (Fanestil & Barrows 1965;Meadow & Barrows 1971). In fact, the net reproductive rates of many tested rotifer species, lineages or sibling species were significantly influenced by temperature (Dong et al 2004;Xi et al 2005Xi et al , 2013Hu et al 2008;Tao et al 2008).…”

The Bdelloidea rotifer, a kind of asexually microscopic invertebrate, is the largest Metazoan group that reproduces only through parthenogenesis. Here the potential evolutionary species composition was analyzed using a coalescent approach to infer independently evolving entities from a phylogenetic tree obtained from cytochrome oxidase I sequences. Three clones (HX4, HX8 and HX19) of Bdelloidea Rotaria rotatoria were selected to be the representatives of three sympatric putative cryptic taxa for detecting the effects of temperature (24, 28 and 32 ℃) on their life history traits. The results showed that the responses of life table parameters to increasing temperature were different among the three evolving entities. Evolutionary species, temperatures and their interaction significantly affected all life history parameters except that evolutionary species did not significantly affect the durations of post-reproductive period and mean lifespan. In addition, the interaction of evolutionary species and temperatures did not significantly affect the durations of postreproductive period, offspring production or net reproductive rate. No matter what the evolutionary species was, the age-specific survival curves tended to decrease earlier and more quickly, and the peak of age-specific fecundity curves appeared earlier with increasing temperature. The three potential cryptic R. rotatoria taxa adopted variable life history strategies, low reproduction and high survivorship at low temperature, as well as high reproduction and low survivorship at high temperature. The similar adaptation abilities of HX4, HX8 and HX19 to water temperatures could be the best explanation for their coexistence in the subtropical shallow pond at a high temperature.

The in£uence of maternal and grandmaternal age on progeny egg-to-adult viability was assessed in Drosophila serrata. Viability in progeny decreased with increasing maternal age. The potential for cumulative age e¡ects was investigated in two environments, one of which involved nutrient and cold stress. Environment in£uenced viability and female age in£uenced progeny egg-to-adult viability across one generation. The in£uence on viability was cumulative across two generations. Females from old mothers, who also had old grandmothers, had the lowest viability in both environments. Grandmaternal e¡ects were associated with a decrease in egg hatch rate whereas maternal e¡ects also involved larval-to-adult viability. The age of the mother and grandmother should be taken into account when evaluating lifehistory traits in Drosophila.

Effect of food availability on the response of planktonic rotifers to a toxic strain of the cyanobacterium Anabaena flos‐aquae

The ability of food concentration to modify the response of zooplankton to toxic cyanobacteria was examined using chronic (lifetime) toxicity tests with two rotifers, Brachionus calyciflorus and Synchaeta pectinata, and a strain of Anabaena flos‐aquae producing the alkaloid neurotoxin, anatoxin‐a. In a clone of S. pectinata, the cyanobacterium decreased both life span and lifetime fecundity to a much greater extent when the availability of food (Cryptomonas erosa) was low. Fecundity was the most sensitive parameter. In one experiment, the cyanobacterium (2.5 µg ml−1) decreased fecundity by 29% at the highest food concentration (2 × 104 cells ml−1) but by 90% at the lowest one (3 × 103 cells ml−1). In two clones of B. calyciflorus, A. flos‐aquae decreased lifespan, fecundity, and population growth rate, but there was only a tendency in one of the clones for the inhibition to be greater at lower food concentrations. The degree to which toxic cyanobacteria affect the population dynamics of susceptible zooplankton taxa in natural communities may be greatly influenced by modifying environmental factors such as food availability and temperature, especially if these factors act additively or synergistically.
