Plant animal interactions in tropical mangrove

Similar contrasts, albeit less pronounced, can be seen in many other animal and plant groups across the same divide. Tropical rainforests occur in regions of the tropics where temperatures are always high and where rainfall exceeds about 1, to 2, mm about 70 to inches annually and occurs fairly evenly throughout the year.

Other species deposit salt in senescent leaves, which later fall off the tree. The amount of rain reaching the ground is also reduced—by as much as 90 percent in some cases—as rainwater is absorbed by epiphytes plants that grow on the surface of other plants but that derive nutrients and water from the air and by tree bark or is caught by foliage and evaporates directly back to the atmosphere.

Disturbance regime alters the impact of dispersal on alpha and beta diversity in a natural metacommunity. Apart from this, faunal elements like zooplankton are responsible for secondary productivity and benthic animals for tertiary productivity. Next, we want to evaluate the general validity of these patterns e.

The monsoon rainfall varies from 3, mm along the Kerala coast and decreases further towards Gujarat coast in the north to a bare minimum of mm. The effect of accretion and erosion seem to be more prominent along the east coast than on the west coast of India.

A developmental oddity or an adaptive structure? Marine Biology 49, Before that time the two parts were separated by a wide expanse of ocean and experienced separate evolution of their biota. Phoenix paludosa and Sonneratia caseolaris are used for human consumption and as cattle feed.

The detritus, besides forming a food source for suspension and deposit feeders, is also consumed by the juveniles of a variety of bivalves, shrimps and fishes, which migrate into the mangrove environments in their life cycle for better feeding and protection.

These organisms in turn feed fish and shrimp, which support wading birds, pelicans, and the endangered Crocodile. During heavy to very heavy floods, these new mangrove formation may be completely washed out. Because of this, light can not penetrate enough in the water and causes in this way damage to mangroves.

In the future, we have to develop much more mechanisms to protect the ecosystem. The main research topic is the connectivity of populations by pelagic early life history stages eggs and larvaewhich can potentially drift with ocean currents hundreds of kilometres.

All aspects of mangroves and their conservation are critically re-examined. The tropical rainforest of Africa was the habitat in which the ancestors of humans evolved, and it is where the nearest surviving human relatives— chimpanzees and gorillas —live still.

After the growth of pioneer species, the dominant or climax vegetation of mangrove species takes over and flourish. Plant species, however, are often quite different among regions.

The total population of the Sundarbans is around 2. At the same time, seedlings of taxa like, Rhizophora, Kandelia, Ceriops or Bruguiera will be established according to their floating height. Decomposition and the one-year flux of debris from fallen lumber in tropical Rhizophora mangle woods.

Nypa fruticans is tapped for an alcoholic drink. This has led some authorities to suggest that the original cradle of angiosperm evolution might lie in Gondwanalanda supercontinent of the Southern Hemisphere thought to have existed in the Mesozoic Era to 66 million years ago and consisted of Africa, South America, Australia, peninsular India, and Antarctica.

The coastal climate is generally uniform except Gujarat coast which experiences drought conditions. In the upstream regions, giant prawns like Microbrachium rosenbergii are also found in large quantities. Only about eight bird species are restricted to mangroves in the Wet Tropics.

More information can be found on the website www. The vertical root is called a pneumatophore and can be as high as several decimeters.Tropical mangrove forest ecosystems rely strongly on trophic interactions between plants and animals in controlling population, community and ecosystem level processes (Robertson ).

Positive plant-animal interactions include litter processing, remineralization of detritus within forests and the removal of particulates from the forests to other near-shore habitats (Cannicci et al.

). Tropical rainforest, also spelled tropical rain forest, They not only retain many primitive plant and animal species but also are communities that exhibit unparalleled biodiversity and a great variety of ecological interactions. The tropical rainforest of Africa was the habitat in which the ancestors of humans evolved.

Structural complexity of seagrass bed including species composition and shoot density is argued to be an important factor determining fish assemblages. However statistical verification of such a relationship is possible only in areas with high species richness of seagrass and fish assemblages which is observed in tropical waters.

Material for this study was collected in three seagrass beds. Srinivasan Balakrishnan, Muthukumarasamy Srinivasan and Perumal Santhanam, Interactions of nutrients, plant growth and herbivory in a Parangipettai mangrove ecosystem of the Vellar estuary, Southeast coast of India, Regional Studies in Marine Science, 5, (19), ().

Mangroves, seagrasses and coral reefs are the major tropical coastal ecosystems of the world. The physico-chemical and biological interactions between the coastal ecosystems have been perceived, but are rarely explored for better understanding of their connectivity.

Mangroves forests and seagrass meadows are the coastal ecosystems of intense nutrient cycling, whereas the coral reef areas are.
