| الوصف: | We present the first quantitative evidence of 2-dimensional non-random spatial struc- ture for in vivo fluorescence distributions measured at scales of centimetres. To determine the pres- ence of non-random structure and to quantify levels of spatial complexity, 2 common geostatistical analysis techniques, namely Moran's I spatial autocorrelation statistic and single-dimension fractal analysis, were employed. Samples were collected at 4 and 2 cm resolution from 2 coastal environ- ments in South Australia; 50% of the distributions were spatially autocorrelated and 60% exhibited fractal scale dependence (with a fractal dimension, DF, ranging from 1.54 to 1.89). Comparison of dis- tributions sampled in the horizontal and vertical indicate that structural complexity is equally impor- tant in both planes. Structural complexity was greater at 2 cm than at 4 cm, suggesting that structure may arise at or below the 2 cm scale. This observation is in direct conflict with the general assump- tion that turbulence homogenises distributions at these scales. |
