The northern Andes harbour a flora that is as species-rich or even richer than the 18-times larger lowland Amazon basin. Gaining an understanding of how the high species richness of the Andean region is generated and maintained is therefore of particular interest. Environmental sorting due to elevational gradients in climate has been emphasized as a driver of vegetation distribution and plant community assembly in tropical mountain areas such as the Andes for two centuries, while alternative… 
The demography of a dominant Amazon liana species exhibits little environmental sensitivity
The limited sensitivity of the vital rates to environmental gradients in the area suggests that ecological generalism contributes to the success of this dominant Amazonian liana.
Species Diversity and Growth Forms in Tropical American Palm Communities
The eight growth forms are differently represented in the palm communities, and the categories Small Palms and Large tall-stemmed Palms dominate the communities both in terms of species richness and in number of individuals.
REVIEW: PART OF A SPECIAL ISSUE ON PALM BIOLOGY Geographical ecology of the palms (Arecaceae): determinants of diversity and distributions across spatial scales
†Background The palm family occurs in all tropical and sub-tropical regions of the world. Palms are of high ecological and economical importance, and display complex spatial patterns of species
Using Potential Distribution Models for Patterns of Species Richness, Endemism, and Phytogeography of Palm Species in Bolivia
Bolivia represents the southern and western distribution limit of many palm species in terms of continental phytogeographic patterns and the greatest palm richness of northern and northwestern Bolivia may be related to the climatic conditions of these zones.
Geographical ecology of the palms (Arecaceae): determinants of diversity and distributions across spatial scales.
Determinants of palm distributions, composition and richness vary with spatial scale, and future studies should target scale-predictor combinations and geographic domains not studied yet to avoid biased inference.
Elevational patterns of species richness and density of rattan palms (Arecaceae: Calamoideae) in Central Sulawesi, Indonesia
We studied species richness and density of rattan palms in 50 plots of 10 × 100 m2 each between 250 m and 2420 m in eight sites in Lore Lindu National Park (LLNP), Central Sulawesi. Rattans were
Four centuries of vegetation change in the mid-elevation Andean forests of Ecuador
Mid-elevation Andean ecosystems have immense species richness and endemism. Taxonomic composition is known to change through time on the eastern slopes of the Andes as a result of climatic change and


Edaphic and Human Effects on Landscape‐Scale Distributions of Tropical Rain Forest Palms
It is suggested that marked spatial heterogeneity in community structure, at small to large scales (0.5-103 ha), may be general among tropical wet forests.
Floristic patterns along a 43‐km long transect in an Amazonian rain forest
1 The floristic variation in Amazonian lowland forests is poorly understood, especially in the large areas of non‐inundated (tierra firme) rain forest. Species composition may be either unpredictable
Geographical and environmental controls of palm beta diversity in paleo-riverine terrace forests in Amazonian Peru
The palm (Arecaceae) community on low paleo-riverine terraces (terrace forest) in the north-western Amazon, is described, and we assessed the importance of environmental differences and geographic
Diversity and dominance in palm (Arecaceae) communities in terra firme forests in the western Amazon basin
1 Current discussions about the structure and functioning of tropical plant communities revolve around whether tropical forests are dominated by sets of widespread and locally abundant species and
Why do mountains support so many species of birds
Although topographic complexity is often associated with high bird diversity at broad geographic scales, little is known about the relative contributions of geomorphologic heterogeneity and
Environmental heterogeneity, recruitment limitation and the mesoscale distribution of palms in a tropical montane rain forest (Maquipucuna, Ecuador)
The study presented here investigated the importance of environ- mental heterogeneity and clumping for the mesoscale distribution patterns of five palm species in old-growth Andean forest
Habitat association among Amazonian tree species: a landscape‐scale approach
1 Unravelling which factors affect where tropical trees grow is an important goal for ecologists and conservationists. At the landscape scale, debate is mostly focused on the degree to which the
Dispersal, Environment, and Floristic Variation of Western Amazonian Forests
The main hypotheses are that species composition is either uniform over large areas, random but spatially autocorrelated because of dispersal limitation, or patchy and environmentally determined, and the uniformity hypothesis gains no support, but the other hypotheses do.
Upslope-Directed Mass Effect in Palms along an Andean Elevational Gradient: A Cause for High Diversity at Mid-Elevations?1
BECAUSE OF HIGH SPECIES NUMBERS AND LOGISTICAL DIFFICULTIES, structure and dynamics of plant populations in tropical mountain forests remain poorly understood. Depending on the plant group, species
Palm distribution patterns in Amazonian rainforests: What is the role of topographic variation?
Abstract Question: Are soil properties and topographic variation related with palm (Arecaceae) species composition and distribution patterns? If so, are species distribution patterns consistent
