This study aimed to assess the population genetic structure of a widespread Neotropical tree species, Simarouba amara, at local, regional and continental spatial scales. We used five microsatellite loci to examine genetic variation in 14 natural populations (N = 478 individuals) of this vertebrate-dispersed rain forest tree species in Panama, Ecuador, and French Guiana. Estimates of genetic differentiation (Fst and Rst) were significant among all but one population pair and global…

Spatial Patterns of Haplotype Variation in the Epiphytic Bromeliad Catopsis nutans

The genetic signature of recent climatic oscillations are likely superimposed upon the distribution of anciently divergent lineages and the unique phylogeographic history of a Neotropical plant species spanning an elevation gradient is highlighted.

Genetic structure of the threatened Phaedranassa schizantha (Amaryllidaceae)

Assessment of population genetic structure and demographic patterns in 11 populations across the range of Phaedranassa schizantha shows that genetic diversity was generally lower in the southern part of the range and was especially low in populations closest to cities.

Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis‐scenario

It is suggested that Andean orogenesis is the main driver of genetic structuring and diversification in O. bataua within northwestern South America.

Genetic variation and structure in the neotropical tree, Manilkara zapota (L) P. Royen (Sapotaceae) used by the ancient Maya

Substantial levels of genetic diversity with minimal genetic structure in M. zapota are consistent with movement of the ancient Maya as they possibly carried fruits and seedlings during immigration, but they may more likely reflect natural processes such as seed and pollen being dispersed widely throughout the tropical forest.

Chloroplast DNA Microsatellites Reveal Contrasting Phylogeographic Structure in Mahogany (Swietenia macrophylla King, Meliaceae) from Amazonia and Central America

It is suggested that the frequent occurrence of hurricanes in Central America, the differences in the glacial histories and in the duration and intensity of anthropogenic disturbance during the late Holocene may have played important roles in the geographic structuring of cpDNA lineages in the two regions.

Population Genetic Structure of the Invasive Red Swamp Crayfish in China Revealed by ITS1 Variation

Phylogenetic trees showed that three major genealogical clusters matched the sample locations well, suggesting that genetic differentiation is created largely by geographic isolation.

The phylogenetic trees showed that some geographical populations were irregularly distributed according to the river systems while others were matched well, suggesting that genetic differentiation is created largely by geographic isolation.

Recent phylogeographic structure in a widespread ‘weedy’ Neotropical tree species, Cordia alliodora (Boraginaceae)

The phylogeographic structure of a widespread and economically important tree, Cordia alliodora, is examined to test the roles of vicariance and dispersal in establishing major range disjunctions, determine which geographic regions and/or habitats contain the highest levels of genetic diversity, and infer the geographic origin of the species.

Amazon diversification and cross‐Andean dispersal of the widespread Neotropical tree species Jacaranda copaia (Bignoniaceae)

This work analysed range‐wide genetic diversity in a widespread pioneer tree species, Jacaranda copaia (Aubl.) D. Don, to characterize phylogeographical structure, date the evolutionary relationships among lineages, and evaluate the role of dispersal and vicariance in establishing the present geographical range.

ARTICLE Palm diversification in two geologically contrasting regions of western Amazonia 1

Aim The subduction of the Nazca Plate and the eastward propagation of the Andean orogenic wedge in western Amazonia caused the formation of arches or ridges that have influenced the modern…

Population genetic structure of mahogany (Swietenia macrophylla King, Meliaceae) across the Brazilian Amazon, based on variation at microsatellite loci: implications for conservation

The finding of local differentiation among Amazonian mahogany populations underscores the need for in situ conservation of multiple populations of S. macrophylla across its distribution in the Brazilian Amazon and indicates the importance of maintaining populations in their diverse habitats, especially in areas with mosaics of topography and soil.

Regional and Population-scale Influences on Genetic Diversity Partitioning within Costa Rican Populations of the Pioneer Tree Vochysia ferruginea Mart

Overall population differentiation was low and within-population diversity high, which fits with the overall pattern of population genetic structure expected for a widespread, outcrossed tropical tree, however genetic diversity was significantly lower and differentiation higher for recently colonised and disturbed populations compared to that at more established sites.

Spatial genetic structure of Simarouba amara Aubl. (Simaroubaceae), a dioecious, animal-dispersed Neotropical tree, on Barro Colorado Island, Panama

The relatively weak genetic structure of S. amara, in comparison to other recent studies, may be explained by pollen and seed dispersal over the 50 ha plot, overlapping seed shadows, and postrecruitment mortality.

Population genetic structure of the endangered tropical tree species Caryocar brasiliense, based on variability at microsatellite loci

The population genetic structure of the endangered tropical tree species Caryocar brasiliense is reported, based on variability at 10 microsatellite loci, suggesting that identity by state and identity by descent have diverged in these populations.

Population genetics of Cordia alliodora (Boraginaceae), a neotropical tree. 1. Genetic variation in natural populations

It is indicated that in situ and ex situ conservation should accord high priority to the dry zone populations of Cordia alliodora; furthermore, conservation of this widespread species would require preservation of multiple populations.

Genetic structure of Mesoamerican populations of Big‐leaf mahogany (Swietenia macrophylla) inferred from microsatellite analysis

The results of this study demonstrate greater phylogeographic structure than has been found across Amazon basin S. macrophylla, suggesting a relatively complex Mesoamerican biogeographic history and lead to the prediction that other Central American trees will show similar patterns of regional differentiation.

Both DNA sequence and nSSR data reflect contrasting demographic histories in lower Mesoamerica and Amazonia, and Amazon populations show weak phylogeographic structure and deviation from drift–mutation equilibrium indicating recent population expansion.
