“…Non‐linear regression equations were calculated using GraphPad prism (GraphPad Software, San Diego, CA, USA) curve‐fitting software. A Runs test determined whether sigmoidal equations described the data adequately ( P = 0.05) (Bradley, 1968). Sethoxydim I 50 values were calculated by fitting data to a linear regression model.…”

“…Data for each replicate were regressed using the following model: y = B + C ( logX ), and included the following parameters: y , ACCase enzyme activity; B , the intercept of the response at the y ‐axis; C , the slope of the response; and X , the dose of sethoxydim. A Runs test determined whether linear equations described the data adequately (Bradley, 1968).…”

Populations of Setaria faberi and Digitaria sanguinalis cross-resistant to sethoxydim and fluazifop-P-butyl were identified in a vegetable cropping system in Wisconsin, USA, in 1991 and 1992 respectively. Experiments were conducted with partially purified acetyl-CoA carboxylase (ACCase) to determine whether resistance to sethoxydim and other ACCase inhibitors in S. faberi and D. sanguinalis resulted from altered enzyme activity. Based on I 50 values (the herbicide dose that inhibited ACCase activity by 50% compared with untreated ACCase), ACCase of the resistant accession of S. faberi was 4.8-, 10.6-and 319-fold resistant to clethodim, fluazifop-P acid and sethoxydim, respectively, compared with that of the susceptible accession. Similarly, ACCase of the resistant accession of D. sanguinalis was 5.8-, 10.3and 66-fold resistant to clethodim, fluazifop-P acid and sethoxydim respectively. These results indicated that resistance to ACCase inhibitors in these accessions of S. faberi and D. sanguinalis resulted from an altered ACCase enzyme that confers a very high level of resistance to sethoxydim.

“…Fama [1965], Blume [1970]). The appropriate way to check this problem is to use a non‐parametric analysis of variance, Friedman's multi‐sample test, (Bradley, [1968] [p. 127]). This was done for exactly the same sample of stocks grouped in the same way.…”

“…The Runs test (Bradley, ) approach suggest that if the abundance of a species declines through time, this decline may be represented by increasing periods during which the species is not observed. This approach allows detection of some runs of absence near the end of the recording period, which are trends identifying declining species.…”

Using sighting records to infer extinction in three endemic Argentinean marsupial frogs

Three species of marsupial frogs of the genus Gastrotheca are at the forefront of amphibian conservation concern in Argentina. Most of the data available on these amphibian species in the country are in the form of museum collections. In this study, we use the recent rediscovery of G. gracilis to test the applicability of a series of probabilistic methods and a trend analysis to analyse the sighting records in the marsupial frog species of Argentina, and to assess the probability that G. christinani and G. chrysosticta are still extant. The results suggest that the two marsupial frog species are still extant, but probably declining. Based on these results, we suggest as a precautionary measure to raise the actual conservation status of these marsupial frog species to Critically Endangered. bs_bs_banner Animal Conservation.

Distribution-free statistical tests.

Abstract: As a result of an extensive survey of the literature, a large number of distribution-free statistical tests are examined. Tests are grouped together primarily according to general type of mathematical derivation or type of statistical "information" used in'conducting the test. Each
