“…Typically, there is a strong positive relationship between the R o and the total number of offspring produced; however, here we notice a consistent weakening of this relationship as we approach lower temperatures. This can be explained by a flattening of the fecundity curve with a decrease of temperature, as observed in our study as well as that of others (Halbach 1970;Snell and King 1977;Xi et al 2005).…”

“…Therefore, much like the work of Snell and King (1977) on the carnivorous rotifer A. brightwelli, our study was designed to explore a number of life history parameters in relation to the cost of reproduction in the rotifer Brachionus calyciflorus at different temperatures. In addition to similar temperaturebased longevity studies using B. calyciflorus in which limited numbers of life history parameters were examined (Halbach 1970;Xi et al 2005), the detailed analysis of interrelationships between the longevity and fecundity described here could provide impetus to future studies that might explore the molecular mechanisms underlying such relationships.…”

We used the monogonont rotifer, Brachionus calyciflorus, to study the effect of ambient temperatures of 16 C, 22 C, and 29 C on longevity and life history parameters. We found that temperature had a significant relationship with longevity. At lower temperature, there was prolongation of the pre-reproductive and reproductive periods, but fecundity was reduced significantly due to suppression of the reproductive rate. When lifespan of short-and long-lived rotifers was compared, we found that the significant longevity difference in these rotifers was due to extension of reproductive and post-reproductive periods. The fecundity was significantly higher in longer lived rotifers due to the extension of the reproductive period, but the reproductive rate was significantly lower in these rotifers. A consistent negative relationship between rotifer longevity and the rate of reproduction was observed at all temperatures, and it was particularly pronounced in rotifers reproducing heavily at the end of the reproductive stage of their life cycle. The combined rate of living/oxidative damage theory may help explain the temperature effects that we observed.

“…At higher culture temperatures, population growth rate, mixis rate, fertilization rate, and resting egg production were different among the rotifer batches (Table I), and these results were similar to what others have found (Hagiware et al 1995, Hu et al 2004, Xi et al 2005.…”

“…Previously it was reported that there were significant dissimilarities in life table parameters between rotifer species or lineages (Ricci 1991;Dong et al 2004;Feng & Xi 2004;Xi et al 2005). The marked differences in life table parameters including principal developmental phases between rotifer evolutionary species may depend on genetic factors.…”

“…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 results of the present study showed that evolutionary species, temperatures and their interaction significantly affected the life expectancy at hatching, net reproductive rate, generation time and intrinsic rate of population growth except that the interaction of evolutionary species and temperatures did not significantly affect the net reproductive rate.…”

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.
