Causes and Consequences of Monodominance in Tropical Lowland Forests

The American Naturalist, 2001
Tropical canopy dominance in lowland, well-drained forests by one plant species is a long-standing conundrum in tropical biology. Research now shows that dominance is not the result of one trait or mechanism. We suggest that the striking dominance of Gilbertiodendron dewevrei in the Ituri Forest of northeastern Congo is the result of a number of traits

Linking regeneration niche to monodominance in biodiverse tropical forest landscapes

Journal of Vegetation Science, 2022
AbstractAimsAlthough monodominance has attracted the attention of ecologists for many decades, few studies have devoted attention to how abiotic factors could influence the occurrence of monodominant forest patches at the biome scale. Here, we assessed whether the occurrence of monodominant forest patches of Moquiniastrum polymorphum (Less.) G. Sancho (

Earthquake disturbance shifts metabolic energy use and partitioning in a monodominant forest

Global Ecology and Biogeography, 2023
AbstractAimBoth macroecology and disturbance ecology have long been used to characterize population‐ and community‐level patterns across scales, but the integration of both approaches in characterizing disturbed ecosystems is rare. Here, we use the maximum entropy theory of ecology (METE) to model the individual size distribution (ISD) of trees in pre‐

Monodominance in an African Rain Forest: Is Reduced Herbivory Important?1

BIOTROPICA, 2000
ABSTRACTTropical monodominant forests in which one tree species dominates the canopy occur in all three major tropical regions, but few studies have focused on the mechanisms responsible for dominance. This study tests the hypothesis that relative to other species in the community, dominant species are well defended and escape herbivore and pathogen ...

Photosynthetically active radiation heterogeneity within a monodominant Congolese rain forest canopy

Agricultural and Forest Meteorology, 2000
Photosynthetic photon flux density (PPFD) regimes within vegetation canopies are intrinsically heterogeneous in time and space. Photosynthesis responds to changes in the intensity and temporal variability of PPFD in a non-linear way. Therefore, it is important to quantify PPFD heterogeneity at short time scales in order to better understand and assess ...

Identifying Dicymbe corymbosa Monodominant Forests in Guyana Using Satellite Imagery

Biotropica, 2009
ABSTRACTThe ectomycorrhizal (EM) canopy tree Dicymbe corymbosa (Fabaceae subfam. Caesalpinioideae) forms monodominant forests in the Pakaraima Mountains of western Guyana. Like other tropical monodominants, D. corymbosa has several life‐history traits that promote conspecific clumping, in contrast to density‐dependent recruitment limitations ...

Monodominance of Parashorea chinensis on fertile soils in a Chinese tropical rain forest

Journal of Tropical Ecology, 2014
Abstract:Monodominance in the tropics is often seen as an unusual phenomenon due to the normally high diversity in tropical rain forests. Here we studied Parashorea chinensis H. Wang (Dipterocarpaceae) in a seasonal tropical forest in south-west China, to elucidate the mechanisms behind its monodominance.

Dead leaf turnover in monodominant forest of the marcescent palm Lodoicea maldivica

Oecologia
The palm Lodoicea maldivica is marcescent, with dead leaves remaining attached to the trunk for an extended period. To investigate how this trait affects the distribution and turnover of dead leaf material in Lodoicea forest, we measured dead leaf production and standing crops of dead leaves attached to palms (DM) and in the litter layer (DL); for ...

Resource acquisition strategies facilitate Gilbertiodendron dewevrei monodominance in African lowland forests

Journal of Ecology, 2019
Abstract Tropical forests are hyperdiverse, yet extensive areas of monodominant forest occur in the tropics worldwide. Most long‐lived and persistent monodominant tree species form ectomycorrhizal fungi symbioses, allowing them to obtain nutrients directly from soil organic matter. This might promote monodominance by reducing nutrient availability to

Leaf herbivory and monodominance in a Cerrado–Amazonia transitional forest, Mato Grosso, Brazil

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2014
Monodominant tropical forests occur on several continents, including the Brazilian Amazon. In this study, we tested the hypothesis that seedling escape from leaf herbivory contributes to the maintenance of the monodominant Brosimum rubescens forest. The study was undertaken both in a monodominant forest of B.
