The lowest nodes of 6-week-old Aesculus turbinata seedlings were treated with uniconazole-P, an inhibitor of gibberellin (GA) biosynthesis, or a mixture of uniconazole-P and GA3 in acetone solution. To the seedling stems, an inhibitor of auxin transport (NPA) or inhibitors of auxin action (raphanusanin or MBOA) were applied in lanolin paste. The seedlings were tilted at a 45° angle and kept for 10 weeks before histological analysis. Decreases in both normal and tension wood formation followed the application of uniconazole-P. The application of GA3 together with uniconazole-P partially negated the effect of uniconazole-P alone. The application of NPA inhibited tension wood formation at, above, and below the lanolin-treated portions. The treatment of raphanusanin or MBOA also resulted in decreases in tension wood formation at the treated portions. The inhibitory effects of these chemicals applied on the upper side of tilted stems or around the entire stem were greater than on the lower side. The application of uniconazole-P in combination with raphanusanin, MBOA or NPA showed synergistic effects on the inhibition of tension wood formation. The results suggest that both auxin and GA regulate the quantitative production of tension wood fibers and are essential to tension wood formation.

AbstractThe mangrove salt marsh snake (Nerodia clarkii compressicauda Baird and Girard) may experience varying levels of foraging success because the prop roots of the red mangrove (Rhizophora mangle L.) have a six-fold variation in density. Adult female N. c. compressicauda were allowed to forage for 24 h on a known density of prey in an enclosed habitat simulating one of four experimental prop root densities. Snake behaviors were recorded during the first hour of each trial, and the number of prey ingested was determined at the conclusion of the trial period. Individuals had the greatest success at the root density most often encountered in their habitat. More time was spent in the water than atop roots; but individuals were less likely to forage in the water at low root densities, suggesting that they, like their prey, may be afforded protection from avian and mammalian predation by the mangrove forest canopy. Mangrove salt marsh snakes spent the majority of time resting motionless and appeared to be opportunistic predators, attempting to ingest prey only during chance encounters.

Fungi of the genus Phytophthora were found to be associated with the initial stages of leaf litter decay of Rhizophora mangle L. and other Rhizophora species in estuarine and coastal marine waters. Phytophthora appears to be an important component of red-mangrove litter degradation systems throughout the tropics, which includes the Atlantic, Pacific, and Indian Oceans. The distributions of Phytophthora vesicula Anastasiou et Churchland and four new species of Phytophthora are discussed, as well as their occurrence in other tropical marine allochthonous spermatophytic leaf litter. The descriptions of the new species and varieties, Phytophthora bahamensis, P. epistomium, P. mycoparasitica, P. spinosa var. spinosa, and P. spinosa var. lobata, are presented.Pythium was rarely observed in the mangrove litter system, although one species, Pythium grandisporangium sp.nov., is described.
