Identifying model groups for tropical rain forest research. Simple criteria can be used to identify lineages most suitable for the study of biome evolution and ecology: 1) the lineage should be ecologically representative of the biome under investigation, 2) species taxonomy and distributions of the lineage should be well-documented, 3) comprehensive phylogenetic hypotheses of the lineage Cited by:   Dynamics of seedling recruitment in an Australian tropical rain forest.

THE RAINFOREST CANOPY. An estimated percent of life in the rainforest exists in the trees, above the shaded forest floor. Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor.

  Disturbances control rainforest dynamics, and, according to the intermediate disturbance hypothesis (IDH), disturbance regime is a key driver of local diversity.

In the second part of the text we discuss the dynamics of tropical rainforests, focusing on gap and edge dynamics, and on the role of seed dispersal on the restoration of degraded rainforest sites. 1.

Arthropods of Tropical Forests provides a comprehensive review of the many recent ecological studies carried out on the most diverse group of organisms on earth living in the most diverse ecosystems.

The book focusses on the temporal and spatial dynamics of the arthropod communities and their resource : Hardcover. Disturbance in a forest’s canopy, whether caused by treefall, limbfall, landslide, or fire determines not only the distribution of well-lit patches at any given time, but also the ways in which the forest changes over time.

It. Tropical rainforest dynamics: a simple mathematical model. A simple model of the forest cycle is based on the rate of formation of light gaps and the subsequent colonization rates for (a) shade-intolerant and (b) shade-tolerant trees. The model was found to be stable with a significant proportion of (a) in the canopy at : M.

Acevedo, J.I. Furtado. The difficulty of access to the high forest canopy has been a determinant in the majority of rainforest studies being groundbased (Sutton ), despite the apparent importance of the canopy in.

Abstract. A systems analysis of tree growth in a tropical rain forest was carried out to develop the simulation model FORMIX for representing inherent growth dynamics of tropical forests and assessing the consequences of logging strategies currently by: 6.

Spatiotemporal analysis of vegetation cover (–) and modelling of its change drivers, the case of Pingtan Island, China. Canopy gaps create a temporary spatial heterogeneity, often allowing pioneer species to establish and grow in mature forests. In this study, we asked whether the above model holds for tropical dry forests in the Florida Keys.

Six hundred and forty-eight canopy gaps in an extensive Key Largo forest were identified with a LiDAR digital canopy by: 4. Rainforests play an important role in the health of the world. Plants, animals, and people all depend on rainforests for many reasons.

A tropical rainforest is filled with wonder and mystery, from the tallest trees in the canopy to the darkest and wettest leaves on the forest floor. The animals that inhabit this biome are varied and exotic. This is the first study that provides insights into the spatio-temporal dynamics of soil bacterial communities in a tropical lowland evergreen rain forest (LTERF).Cited by: 4.

Gap formation and closure represent important disturbance events in forests, but the processes involved are still poorly understood. We use models, which we and others previously developed, to make long-term predictions of tropical forest gap dynamics based on Barro Colorado Island by: 5.

Given their steep environmental gradients, the effects of changing temperature and rainfall on forests are expected to be most quickly observed on elevational transects, and a growing literature supports this expectation [ 6 ], [ 7 ], [ 40 ].Cited by: Propagation of local interactions create global gap structure and dynamics in a tropical rainforest C.

Methods. The book remains unique in linking rain forest biology and ecology with silviculture, and with concerns over sustainable resource utilization and the future of the tropical rain forests.

The biome can be divided into the following habitats: Lowland rainforest includes most of the eastern part of the biome.

It is dominated by large trees with a ground layer of aroids. As a partial explanation for the maintenance of high tree diversity in wet tropical forests, Janzen () and Connell () independently hypothesized that natural enemies act to increase spacing within these tree populations through disproportionately high attack on progeny near adults.
