Ptychomya Neuquén

132 specimens of Ptychomya from the Agrio Formation Lower Valanginian to lowest Barremian, Neuquén Basin, west-central Argentin

Performance in host cacti.

<p>Mean relative performance (and 95 % confidence intervals) for <i>D. buzzatii</i> (circles) and <i>D. koepferae</i> (triangles) reared in their natural hosts (<i>O. sulphurea</i> and <i>T. terschekii</i>) and an artificial novel host made with <i>Opuntia</i> tissue added with alkaloids extracted from the columnar <i>T. terschekii</i>.</p

Treatments Coefficients of Variance.

<p>Coefficients of variance (CVs) for a) increasing concentrations of the alkaloid fraction extracted from <i>T. terschekii</i>, b) increasing concentrations of the non-alkaloid fraction extracted from <i>T. terschekii</i> and c) the natural hosts and the novel artificial host for <i>D. buzzatii</i> (grey bars) and <i>D. koepferae</i> (black bars). Confidence intervals were estimated via bootstrap (see text).</p

Coefficient of Variation and Performance correlation.

<p>Association between the coefficient of Variation (CV) and the mean relative performance considering all treatments in <i>D. buzzatii</i> (circles) and <i>D. koepferae</i> (triangles). Linear trends are shown.</p

Performance as a function of concentration.

<p>Mean relative performance (and 95 % confidence intervals) as a function of concentration for a) <i>D. buzzatii</i> and b) <i>D. koepferae</i> reared in medium with the alkaloid fraction (black symbols) or the non-alkaloid fraction (white symbols) extracted from the columnar cactus <i>T. terschekii</i>. Linear trends are shown.</p

Performance scores and assessed traits.

<p>Mean values for each trait measured (and standard error) in each treatment and the corresponding performance index and coefficient of variation for both <i>D. buzzatii</i> and <i>D. koepferae.</i></p>a<p> <i>O. sulphurea</i> + alkaloids from <i>T. terschekii</i>.</p

Regression slopes of assessed traits.

<p>Slope values of regressions for each trait in both increasing fraction treatments (Alkaloids and Non- alkaloids concentrations) for both <i>D. buzzatii</i> and <i>D. koepferae.</i> Asterisks denote significant regressions (p<0.05).</p
