A review of the phylogenetic relationships of the subfamilies of Simaroubaceae is presented and the distribution patterns of the American genera are discussed. Engler's six subfamilies are evaluated and the three subfamilies represented in the Americas and their included genera are discussed in detail. The eight American genera fall into three broad distributional categories: widely distributed throughout the neotropics, limited to northern South America, and disjunct between the West Indies, Central America and Mexico and southern South America. These distributions are discussed and interpret

In the course of a detailed molecular study of the tribe Gochnatieae (Compositae: Gochnatioideae) it became apparent that the genus Gochnatia (sensu Cabrera) was not monophyletic but composed of a number of morphologically, geographically, and molecularly distinct clades. All but one of these clades had previously been recognized at the generic or sectional level and therefore had a name that could be applied. However, one clade, whose members are from Mexico and adjacent parts of the United States, had never been recognized as a distinct taxon. The Mexican clade is the sister group of the Car

Abstract The intraspecific evolutionary history of South American xerophytic plant species has been poorly explored. The tree species Prosopis chilensis has a disjunct distribution in four South American regions: southern Peru, southern Bolivia, central–western Argentina and central Chile. Here, we combined phylogeographical (based on chloroplast and nuclear markers), morphological and climatic data to evaluate the relative contribution of historical demo-stochastic and adaptive processes in differentiating the disjunct areas of distribution. The results obtained with the two molecular markers

The historical biogeography of the major South American forested biomes has long intrigued scientists. Paleoclimatic events during the last 130 thousand years promoted connections between forested biomes in the Neotropical region, leading to disjunct distributions of some of the biota. In this context, MacConnell’s Bat, Mesophylla macconnelli, appears to represent a forest-restricted species with its current distribution bisected by dry areas. In this study, we infer past connections between the Amazonia and Atlantic Forest using MacConnell’s Bat and ecological niche models. We obtained 681 re

Plagiodontes dentatus (Wood, 1828) is the type species of a South American genus including eight named species that show a high degree of local endemism. Due to some misidentifications with P. multiplicatus (Doering, 1874) and P. daedaleus (Deshayes, 1851), P. dentatus has been cited as inhabiting two disjunct areas with quite different ecological conditions. In this paper the identity of this morphospecies is clarified through a study of shell sculpture and apertural teeth data, and a comparison with the smaller adult specimens (<25 mm long) of its closest species, P. patagonicus (d’Orbign

Abstract Croton is one of the largest angiosperm genera, with &gt; 1200 species in the tropics worldwide. The arborescent Croton section Cleodora stands out for its disjunct geographical distribution with two main centres of diversity in the Amazonian and Atlantic Forest regions, separated by the Caatinga, Cerrado and Chaco biomes (the ‘Dry Diagonal’). This disjunction is found in other Neotropical lineages and attributed to Neogene geological and climatic events. We inferred a nearly complete phylogenetic reconstruction of Croton section Cleodora based on DNA sequences of nuclear ITS and

In this study, we aim to understand the boundaries and the species evolutionary relationships in Mesochila, which includes 20 species arranged into three subgenera. We also conducted a biogeographic analysis that allowed us to identify the major events that shaped the currently disjunct distribution of the group. Our analyses were performed employing four major phylogenetic algorithms: equal and implied weight parsimony, maximum likelihood and Bayesian inference. Phylogenetic analyses, including 25 taxa (all 20 species in the genus plus five outgroups) and 37 characters, indicated that Mesochi

The results cover a time period from around A.D. 750–1400, and a spatial distribution from southern Colorado to northern Chihuahua.

Much of the immense present day biological diversity of Neotropical rainforests originated from the Miocene onwards, a period of geological and ecological upheaval in South America. We assess the impact of the Andean orogeny, drainage of Lake Pebas and closure of the Panama isthmus on two clades of tropical trees ( Cremastosperma , ca 31 spp.; and Mosannona , ca 14 spp.; both Annonaceae). Phylogenetic inference revealed similar patterns of geographically restricted clades and molecular dating showed diversifications in the different areas occurred in parallel, with timing consistent with Andea
