Analysis of elemental composition and stoichiometry of adult <i>Rivulus hartii</i> using a general linear model (GLM) and variance decomposition (η²).

<p>All values are F ratios, and symbols indicate degree of significance. DF is degrees of freedom used for each variable. C∶P, N∶P and C∶N were log transformed before analysis.</p>**<p>indicates P<0.01.</p>*<p>indicates P<0.05.</p>#<p>P∼0.043.</p

Spatial variability in the organismal stoichiometry of adult <i>Rivulus hartii</i>.

<p>Stream and the interaction of stream×community are the strongest predictors of elemental composition and organismal stoichiometry of <i>R. hartii</i>. Values are least squares means generated from a general linear model (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032713#pone-0032713-t003" target="_blank">Table 3</a>). They are standardized to body size = 35 mm. Community designations are RO = <i>Rivulus</i> Only, RG = <i>R. hartii</i> and Guppies, HP = High Predation sites. ARM is the Arima, ARP is Aripo, GUA is Guanapo, MAR is Marianne, QUA is Quare and TUR is the Turure.</p

Correlations between body size, elemental composition or organismal stoichiometry of adult <i>Rivulus hartii</i>.

<p>Correlations between body size, elemental composition or organismal stoichiometry of adult <i>Rivulus hartii</i>.</p

A statistical assessment of how much of the stream effect in organismal stoichiometry is described by the quality of benthic resources or by the overall availability of resources.

*<p>values were log transformed prior to analysis.</p

Correlations between resources and organismal stoichiometry of adult <i>Rivulus hartii</i>.

<p>Different aspects of the organismal stoichiometry of adult <i>R. hartii</i> are significantly correlated with the invertebrate standing stocks (a), with the stoichiometry of epilithon (b), and with the stoichiometry of benthic organic matter (c).</p
