Variations in the survival probabilities of the PVC-protected red mangrove propagules: testing the encased replanting technique.

摘要: The EcoElectrica Mangrove Planting Project, a five-year voluntary effort, has the purpose of testing recently developed mangrove planting technique at site in Penuelas, Puerto Rico. goal project is to provide empirical validation promote or improve be used recovering ecosystems Rico and United States. research presented herein analyzed information collected on first two years project. proportions remaining casings seeds per study zone were compared using chi-square distribution. Zone 1 had least pipes lost while 4 most (p < 0.05). Forty-three percent remained casing, 26% 2 = 0.03). Median growth rates showed that highest median rates. Survival analysis described survival experience seeds, differences probabilities with log-rank test. better Zones 2, 3 0.0001). for being free spots over 60% during whole period. No significant observed use-or-no use casing extensions 0.40), nursed 0.26). Differences might attributed variations wave energy, depth substrate conditions. This hypothesis will evaluated second phase study.
