Studies on the Growth of Red Mangrove (Rhizophora mangle L.) 4. The Adult Root System

  title={Studies on the Growth of Red Mangrove (Rhizophora mangle L.) 4. The Adult Root System},
  author={A. M. Gill and Philip Barry Tomlinson and Harvard Forest},
Aerial roots in Rhizophora arise from stems, branches, and secondarily thickened, anchored, aerial roots, but only after injury from unanchored aerial roots. Lateral subterranean roots are abundantly developed upon penetration of a mud substrate whereupon the histology of the root undergoes marked and abrupt changes so that chlorophyll is no longer developed, trichosclereids no longer differentiate, tannin cells become few, the cortex becomes markedly lacunose, and the sequence of protoxylem…

It has been verified that the propagule is stem from end to end and does not present radicle, that is, under the plumale there is the hypocotyls without a root, demonstrating that there is no root, as 19th century researchers claimed.

Does the Wood-borer Sphaeroma terebrans (Crustacea) Shape the Distribution of the Mangrove Rhizophora mucronata?

Sediment characteristics, vertical height in the tidal zone, and direct exposure to incoming water are the major factors controlling the abundance of S. terebrans in red mangrove forests in East Africa.

Root biomechanics in Rhizophora mangle: anatomy, morphology and ecology of mangrove's flying buttresses.

This study tests the hypothesis that rhizophore architecture in R. mangle co-varies with their proximity to the main stem, and with stem size and crown position, and provides a unique strategy to increase tree slenderness and height in the typically unstable substrate on which the trees grow, at a site that is subject to frequent storms.

Palm snorkelling: leaf bases as aeration structures in the mangrove palm (Nypa fruticans)

Structural evidence is provided indicating that N. fruticans has evolved a unique type of air-supplying structure in the mangal habitat, ensuring the persistence of aeration structures.

Growth and survival of aerial roots of hemiepiphytes in a lower montane tropical moist forest in Panama

Long-term measurement of growth, dieback and mortality of aerial roots of hemiepiphytic plants in a lower montane moist tropical forest in western Panama was used to elucidate life-history strategies of hemispecies from two families, suggesting that only those Araceae hemiePiphytes that produce a large number of aerial Roots or are located close to the ground are likely to reach the soil.

Soil aeration as an ecological factor governing mangrove zonation

The growth of both Rhizophora mangle L. and Rhizophora mucronata Lamk. in saline sand was highly promoted by flooded, reducing conditions in comparison to drained, aerobic conditions, showing the

On the occurrence of marine fungi in the diet of littorina angulifera and observations on the behavior of the periwinkle

The feeding and resting patterns of Littorina angulifera, the southern periwinkle, were observed in mangrove habitats of Belize (Central America) and the leaf tissue under the area of shell attachment becomes meristematic, separating dead tissues from healthy mesophyll.


Examination of the impact of the boring isopod Sphaeroma peruvianum and encrusting barnacle Balanus spp.

The roots of blue carbon: responses of mangrove stilt roots to variation in soil bulk density

Variation in soil BD has major implications for C sequestration in Rhizophora-dominated mangroves because it increases total root biomass and primary root diameter, while the primary root length decreased.



Studies on the Growth of Red Mangrove (Rhizophora mangle L.) 3. Phenology of the Shoot

An analysis of shoot extension growth of Rhizophora mangle is presented, based on the continuous observation of a small population over a period of two years. This provides phenological information


The present investigation focuses on the gas exchange in roots of plants growing in water or mud which is poor in oxygen, and on the vertical air-roots which protrude in great numbers from the mud under and around Avicennia bushes or trees.

Sphaeroma terebrans: A Threat to the Mangroves of Southwestern Florida

A wood-boring isopod is destroying the prop roots of red mangroves along the southwestern coast of Florida to such an extent that the Ten Thousand Islands and mangrove fringes of the mainland are steadily shrinking.

Evidence for injury as a cause of tree root branching

Abnormalities in the primary xylem are characteristic of the lateral and terminal branching induced by root tip decapitation. Similar abnormalities in old, excavated root branches are evidence that
