Canopy removal experiment and recovery length

Data from two manipulative experiments investigating the effect of different level canopy removal on algal turf invasion in Capraia Island. <b>-RECOVERY LENGTH EXPERIMENT-</b>Datasets named <b>Rec.len_HSRturf_Capraia_2014 </b>and <b>Rec.len_HSRturf_Capraia_2015</b><b> </b>include data on propagation of algal turf for different level of canopy removal in 8 90x30 cm experimental transects. In each transect two region of different quality were produced: a cleared patch (30x30cm), where all erect organisms were removed and a canopy-degraded region (of 60x30cm) which was allocated to the following conditions: 0%, 25%, 50% and 75% of canopy removal. The cleared patch and canopy-degraded region were sampled at the scale of 2 x 2 cm, yielding 675 observations for each transect. Algal turfs cover was assessed twice: after one and two years from the set-up of the experiment (July 2014, July 2015).Datasets named <b>Rec.len_C.amentacea_2014</b> and <b>Rec.len_C.amentacea_2015</b> include data of <i>Cystoseira amentacea</i> cover of cleared patches in and canopy degraded region for each transect. <b>-CANOPY REMOVAL EXPERIMENT-</b>The dataset named <b>Exp.Can.rem_HSRTurf_2015</b> includes data of turf cover for different level of canopy removal (0%, 25%, 50% and 75%). 8 transects of 60 x 30 cm were randomly assigned that to these treatments:0%, 25%, 50% and 75% of canopy removed. Visual estimates of percentage cover of algal turfs was obtained by sampling these transects in July 2015 as described above. Dataset named <b>Exp</b><b>Canrem_</b><b>C.amentacea_2015 </b>include data of <i>Cystoseira amentacea</i> cover for each experimental transect.<b>-R SCRIPTS </b>The R file named <b>Maximum-Likelihood</b> estimation includes the script to conduct the maximum likelihood estimation of Turf-<i>Cystoseira </i>model parameter. The R file named <b>Rec_len_Bootstrap</b> includes the script to compute recovery length metrics (Half-point recovery length (<i>L_half</i>) and the Exponential recovery length (<i>L_exp) )</i> and the bootstraps standard errors.
