Fig. 5. Relative mean GSI vs. relative mean HSI of color pattern variants of Cichla temensis. Points for GSI represent the mean value for each CPV grade as compared to the range encountered. Points for HSI represent the mean value for each CPV grade compared to the range encountered.
Fig. 3 in Geometric morphometric analysis of cyclical body shape changes in color pattern variants of Cichla temensis Humboldt, 1821 (Perciformes: Cichlidae) demonstrates reproductive energy allocation
Fig. 3. Biplot of the uniform components in each direction (UniX and UniY) of morphometrical differences in 80 specimens of Cichla temensis in 4 color variation patterns (CPV) as measured by 9 Thin Plate Spline (TPS) distortion variables (V1-V9). Colored numbers indicate the CPV grade of individuals. The total spread of scores among individuals of each CPV are indicated by an envelope (solid line polygon) calculated as the minimum convex hull for that group. Position in the plot relative to other individuals indicates the degree of similarity in morph. Vectors point in the direction of gradient change for that TPS variable and the magnitude indicates the strength of the gradient. Angles between vectors indicate the TPS interset correlations.

Fig. 2 - Average temperatures in September (top), October (middle), November (bottom) recorded from 2011 to 2019. The months of October and November 2011 were among the coldest ones, while the month of September 2011 was the hottest in the considered period. Please, note that the greatest difference in temperature was recorded between September and October 2011. The climatic data were obtained from the website of ARSIAL - the Regional Agrometeorological Service of Lazio (www.arsial.it) and refer to Corchiano station (Viterbo), around 10 km away from the study area. / Temperature medie nei mesi di Settembre (in alto), Ottobre (in mezzo) e Novembre (in basso) registrate dal 2011 al 2019. I mesi di Ottobre e Novembre 2011 sono stati i più freddi, mentre il mese di Settembre 2011 è stato il più caldo nel periodo considerato. Si noti che tra Settembre e Ottobre 2011 si è registrata la maggiore differenza di temperatura. I dati climatici sono stati tratti dal sito web di ARSIAL - Servizio Agrometeorologico della Regione Lazio (www.arsial.it) e si riferiscono alla stazione di Corchiano (Viterbo), a 10 km circa dall'area di studio.
