    This simplification results in three regions: the tropical forest (dark green color) is defined as the area from 71°W to 50°W, as this is an area mostly covered by the forest biome, except where the LONS08 map indicates portions of the savanna biome in the southeastern boundary of the Amazon forest (from 60°W to 50°W); the forest–savanna Cited by: The Biome Concept in Ecology I magine that you are on safari on an East African savanna and one of your group shouts, “Look over there, a cactus tree!” With your training in botany, you know imme-diately that this can’t be so, because the cactus family (Cactaceae) is restricted to the Western Size: 2MB.

    General Overviews. The savanna biome has been the subject of a number of broad overviews. In the landmark Ecosystems of the World series Bourliére provides a comprehensive overview, Tothill and Mott provides global treatment of savannas, and the ecology of tropical savannas is covered in Huntley and Walker , but none of these books are currently in print. Tropical savanna and forest are recognized to represent alternate stable states, primarily determined by feedbacks with fire. Vegetation–fire dynamics in each of these vegetation types are largely determined by the influence of the vegetation on fire behavior, as well as the effects of fire behavior on tree mortality, topkill (defined here as complete death of the aerial biomass, regardless Cited by:

The Nature and Dynamics of Forest-Savanna Boundaries addresses many themes and links with a great number of the interest groups concerned with current ecological and environmental research in the It should form part of the reading of all concerned with the fate of tropical forest and savanna regions of the world.

Originating from part of a symposium, organized by the British Biogeography Research Group and the British Ecological Society, held in Glasgow in Januarythis book addresses ecological and environmental research themes in the humid tropics with particular reference to boundaries between forest and savanna.

The differences in the ecology of savanna and forest trees suggest an underlying tradeoff between fire tolerance and competitive ability. Adaptations to the savanna environment, such as large investment in carbohydrate reserves (Hoffmann et al. ), root biomass (Hoffmann & Franco ) and bark ( by: Ecological thresholds at the savanna‐forest boundary: how plant traits, resources and fire govern the distribution of tropical biomes.

Ecological thresholds at the savanna-forest boundary: How plant traits, resources and fire govern the distribution of tropical biomes. In contrast to savanna trees and grasses, forest trees are fire-prone and shade tolerant, adapted to persist in conditions of low light availability and in the absence of fire (Ratnam et al., ; Rossatto et al., ).

Thus, when fires are absent and water supply is suffi-cient, forest trees outcompete grasses and savanna trees be-cause Cited by: We quantified frost damage and air temperature across a network of 30 permanent plots distributed across tropical savanna–forest boundaries in Brazil during an uncommonly hard frost.

In this text, James Fairhead and Melissa Leach question these entrenched assumptions. They show, on the contrary, how people have created forest islands. Grasslands differ strikingly from forests in their ecology and in the nature of threats to their future.

Little is known if these barriers cause divergence in species composition between the overstorey and understorey strata in these vegetation by: 1. The mosaic of forest and savanna vegetation found along the northern margin of West Africa's moist forest zone has generally been understood in policy circles as a degraded and degrading forest landscape, following savannisation by its farming by: The savanna–forest boundary is commonly abrupt, with savanna grading into forest over distances of a few meters.

Climate, fire, hydrology, herbivory, as well as soil nutrients, texture and depth are all important in determining the location of savanna and forest (Furley ; Hopkins ; Tinley ), Cited by: Summary 1. Fire is important in the dynamics of savanna-forest boundaries, often maintaining a balance between forest advance and retreat.

The boundary between these two systems is perhaps the most basic divide in the ecology of West Africa. This boundary is gradual; there is no abrupt change from forest to savanna.Vegetation ecology of forest-savanna ecotones in the Comoé National Park (Ivory Coast): Border and ecotone detection, core-area analysis, and ecotone dynamics Dissertation zur Erlangung des akademischen Grades Doctor rerum naturalium (Dr.
