Sentence examples for survivorship pattern from inspiring English sources

This survivorship pattern was seen for early American toads and for both early and late stages of spring peepers and green frogs.

Although this number was higher than those reported in literature for older larvae (0 100 individuals m [ 31]), given the typical larval survivorship pattern [ 33], we assumed that the starting density was an ecologically realistic estimate for our study population.

The survivorship pattern for late American toads revealed that each individual concentration of atrazine was significantly different from the control (p < 0.01); however, none of the survivorship curves for the individual levels of atrazine was significantly different compared with the others (low and medium, p = 0.203; low and high, p = 0.792; medium and high, p = 0.240).

Age structure represents the proportion of individuals in each age class and can indicate survivorship patterns or direction of change in population size.

Indeed, body size has featured prominently in attempts to explain temporal and spatial trends in fossil species duration [18] [20], directional changes within lineages [21] [26] and survivorship patterns during mass extinction events [27]; [but see 28].

During the winter months, survivorship patterns followed the GMH: survivors (i.e. those with higher fitness) exhibited faster mean larval growth and had shorter PLDs than the intermediate group (Table 4, Fig. 5).

The remaining 14.5% of this field-grade atrazine contains other chemicals (e.g., surfactants) that may have an impact on survivorship patterns of larval amphibians.

Unlike survivorship patterns of the other species, which consistently dropped below 15.00%, the probability of survival for Rana species never dropped below 33.33%.

After scores had been assigned in this fashion, subjects were divided into two equally sized groups, based upon whether assigned scores were above or below the cohort median, and we evaluated the survivorship patterns of the two groups.

Others have studied the effects of atrazine on larval amphibians using atrazine levels ranging from 0.01 to 47,600 ppb (Allran and Karasov 2000; Detenbeck et al. 1996; Hayes et al. 2002; Howe et al. 1998; Larson et al. 1998), but none have reported the survivorship patterns observed in our study.

For diseases with a prolonged period of latency, we also find that the number of people with latent infection and the proportion of individuals that progress from latency to active disease differ between models that assume different patterns of survivorship.
