<i>Posidonia</i> Evolution.

<p>Posidonia evolution time line for the past 100 million years and current global distribution of Posidonia genus (in green color) in relation to mean ocean temperature. Climate differences as; Polar: purple color (< 4°C), Temperate: blue color (4°C–24°C), and Tropical: pink color (> 24°C). Green spots into the yellow circle point out the place with the first fossil Posidonia spp. records (Posidonia parisiensis), which are dated from middle Eocene to the top of the Oligocene (48.60000 to 23.03000 Ma).</p

Fotobiologycal parameters and dry weight comparison of three <i>Posidonia</i> species.

<p>(R) Respiration, (N.P.) Net Production, (G.P.) Gross Production, (D.W.) Dry Weight and (Fv: Fm) maximum PSII photochemical efficiency <i>in P</i>. <i>australis</i>, <i>P</i>. <i>sinuosa</i> and <i>P</i>. <i>oceanica</i> seeds (mean ± s.d.). R, NP and GP were measured at 300 μmol m^-2 s^-1 and 19°C. Oxygen expressed as mg O2 gdw⁻¹ h⁻¹ and dry weight in grams. Results of ANOVAs (p values) comparing R, NP, GP, DW and (Fv: Fm) in the three species are included.</p><p>Fotobiologycal parameters and dry weight comparison of three <i>Posidonia</i> species.</p
