  Examples include bird dispersal of parasitic mistletoes to appropriate host trees (Davidar ), ant dispersal of seeds that establish better in and around ant nests than elsewhere (Beattie ), and jay or nutcracker dispersal of pine and oak seeds to forest edges or openings (Vander Wall ). Seeds can also be dispersed to forest light Cited by:   The dispersal system of Palicourea rigida (Rubiaceae), a common woody species of neotropical savannas, was studied in a seasonal Venezuelan savanna. Production and consumption of fruits, dispersal agents, feeding behaviour, transport and effects on seed viability, were investigated by field observations, cage experiments and viability by: The role of soil seed banks in regeneration in canopy gaps in Australian tropical lowland rain forest — preliminary field experiments. Malaysian Forester – Google ScholarCited by: Seed dispersal by fishes, or ichthyochory, is an ancient (possibly Paleozoic) ecological interaction that is beginning to receive more attention as new evidence demonstrates that the consumption of fruits by fishes is not a rare process concerning just a few fish and plant species in a particular area (Correa et al., , Galetti et al., , Lucas, , Anderson et al., ).Cited by:

Highlights Current knowledge of frugivory and seed dispersal by hornbills was summarized. Hornbills are able to disperse a diverse array of fruits in tropical forests. Hornbills move many of the seeds far from the parent plants and disperse intact seeds. Hornbills are capable of dispersing seeds over several kilometers. Hornbills provide excellent seed dispersal services to tropical Cited by: This book presents current knowledge of seed fate in both natural and human-disturbed landscapes, from various regions of the world. Habitats considered range from mountain and arid deserts in the temperate zone, to savanna and lowland rainforests in tropical regions of the world. Particular attention is paid to plant diversity conservation when seed removal is.   Introduction. The survival of seeds and the initial establishment of seedlings are key stages determining plant population dynamics and community structure (Webb & Peart, ; Harms et al., ; Green et al., ).One potentially important source of seed mortality is pre‐dispersal predation by insects, particularly Coleoptera, Lepidoptera, Diptera and Cited by: 3. The lowland tapir Tapirus terrestris is the largest herbivore in the Neotropics and feeds on a large quantity of fruits, often ingesting the seeds and defecating them intact.

In this elegant book, we have defined ‘Tropical Forests’ broadly, into five different themes: (1) tropical forest structure, synergy, synthesis, (2) tropical forest fragmentation, (3) impact of anthropogenic pressure, (4) Geographic Information System and remote sensing, and (5) tropical forest protection and by: 3. In fact, it is well established that large seeds are common in tree species (Foster & Janson, ), because large seeds have establishment advantages under closed canopy forests. In contrast, herbs and shrubs tend to have small seeds and are frequently represented in savannas, forest edges, and open canopy forests (Laurance et al., Author: Pablo R. Stevenson, María Clara Castellanos, T Juliana Agudelo. TROPICAL FOREST. Many tropical forests are highly diverse. High diversity and the lack of a reliable method to age trees and measure their growth without long-term study, combine to make tropical forests more difficult to understand mechanistically than temperate forests. Experimental studies of post-dispersal seed predation on rain forest.

From tofield data were collected on comparative seed dispersal and natural forest maintenance in the species-rich, disturbed, tropical lowland forest biocoenosis of Shimba Hills National Reserve, which is located south of Mombasa, by: However, the main emphasis of this work is focused on seed dispersal (sensu lato), natural forest regeneration and an improved understanding of the function and maintenance of the local biocoenosis.

Seed-dispersal ecology in tropical montane forests (TMF) differs in some predictable ways from tropical lowland forests (TLF). Environmental, biogeographic and biotic factors together shape dispersal syndromes which in turn influence forest structure. T.R.

By comparing seed rain, seedling and sapling community structures we assessed the possible role played by vertebrate seed dispersal as a structuring factor in advanced regeneration of closed-canopied sites in the tropical rain forest of Los Tuxtlas, by: Vertebrate-dispersed seeds from the Seed dispersal and forest regeneration in a tropical lowland biocoenosis book forest moved farther into the field than wind-dispersed seeds, but seeds of both types moved similar distances from field into forest.

Where natural regeneration is possible at all, it requires the input of plant seeds through seed dispersal from the forest matrix. Zoochorous seed dispersal – the major seed dispersal mode for woody plants in tropical forests – is particularly important for natural regeneration.

Data collected on a free ranging group of Tana River mangabeys (Cercocebus galeritus) indicates that this endangered primate species, which has previously been regarded as a seed predator, plays an important role in seed dispersal and do contribute to the regeneration of a highly fragmented gallery forest.

We observed fruit handling behavior and the post-dispersal fate of seeds Cited by: 1. Many carnivorous mammals consume fruits and disperse the intact seeds to specific sites. Few studies have attempted to quantify this seed dispersal or evaluate its effectiveness, despite its potential importance and functional uniqueness.

In the study reported here, we found that a frugivorous carnivore, the common palm civet (Paradoxurus hermaphroditus), generated seed Cited by: However, few studies have been conducted on the natural regeneration necessary to restore these forests.

It is listed as Least Concern on the IUCN Red List since Class: Mammalia. Patterns of seed dispersal significantly affect plant demography, dynamics and succession. In the tropics, the majority of tree species bear fruits that are adapted to animal-mediated dispersal.

Be-cause few tropical trees produce seeds with long dormancy mechanisms (GarwoodBaskin & Baskin ), advanced forest regeneration results from relatively recent input of seeds from the seed rain. Although a variety of dispersal mechanisms are found within tropical forests, most plants pro.

The concept of seed dispersal quality has been central to discussions of fruit-frugivore coevolution. Schupp thoroughly reviews data bearing on this concept, constructs a hierarchical framework for viewing disperser effectiveness, and points out that disperser effectiveness depends on both the quantity and quality of seed dispersal.

An analysis of the flowering plant flora of a lowland moist forest in central French Guiana revealed 25 species with adaptations for epizoochorous seed dispersal by barbs, hooks, or spines (stick-tights).

Adapted from figure 8 in Augspurger, C. K., Franson, S. E., Cushman, K. C., & Muller‐Landau, H. C. ().The astounding richness and biodiversity of tropical forests is rapidly dwindling. This has severely altered the vital biogeochemical cycles of carbon, phosphorus, nitrogen etc.

and has led to the change in global climate and pristine natural ecosystems. In this elegant book, we have defined "Tropical Forests" broadly, into five different themes: (1) tropical forest structure. Several factors can limit the rate of forest recovery, including lack of soil nutrients, competition with aggressive grasses, seasonal droughts, low rates of seed colonization, and predation on both seeds and seedlings [1 –2].However, a major factor that often limits forest recovery is inadequate seed dispersal [].When seeds are dispersed by animals, different Cited by: 9.
