Article
Full-text available
The topographic gradients of the Tropical Andes may have triggered species divergence by different mechanisms. Topography separates species’ geographical ranges and offers climatic heterogeneity, which could potentially foster local adaptation to specific climatic conditions and result in narrowly distributed endemic species. Such a pattern is foun...
Article
In geographically and ecologically heterogeneous landscapes, such as tropical mountains, widely distributed species may be informative proxies for studying landscape and climatic evolution. We explore historical vicariant and dispersal processes that may have determined the genetic structure and variation of a palm species complex living in cloud f...
Article
Full-text available
Biological dispersal is increasingly seen as a primary driver of speciation across the tropical Andes. Similarly, growing evidence suggests that the Northern Andes cordilleras formed as disconnected segments, at least until the late Miocene. For montane species, this discontinuity can hinder dispersal to the different mountain segments. Hence, unde...

Aparte del prologo escrito por Dubán Canal: "El presente documento constituye un aporte invaluable de 9 mujeres y 6 hombres colombianos quienes dedican sus esfuerzos al conocimiento de los atributos de los bosques andinos del país. Los estudios presentados son tan diversos como los Andes mismos e incluyen aspectos relacionados con el origen de la d...
Article
Full-text available
• The protection of ecosystems with high diversity, such as coral reefs, is not an approach that guarantees their conservation. Thus, maintaining connectivity among coral populations over the long term is a strategy that should be adopted in order to protect diversity and ecological processes. Although coral reefs in Colombia are highly diverse, th...
Article
Solitary, dioecious, and mostly endemic to Andean cloud forests, wax palms (Ceroxylon Bonpl. ex DC. spp.) are currently under worrisome conservation status. The establishment of management plans for their dwindling populations rely on detailed biological data, including their reproductive ecology. As in the case of numerous other Neotropical palm t...
Article
Full-text available
The cloud forest of the Andean Region contains a high biodiversity. Unfortunately, human land use has caused most of the forest to become fragmented, negatively impacting many species due to the reduction of and constant change within the local habitat. In Colombia, these fragmentation triggers can include agriculture, livestock, and corridors for...
Conference Paper
Full-text available
Forearc basins are highly sensitive to modification in the subduction zones, including changes in parameters such as convergence rate and obliquity, and the nature of the subducting lithosphere (i.e. age, thickness, thermal state, etc.). Therefore, by characterizing their stratigraphic and provenance records, together with the exhumation history of...
Article
Full-text available
Recent field work and the study of new collections have revealed that the Andean palm Aiphanes parvifolia, as interpreted in the most recent monograph of the genus, actually included five species. Three of them, Aiphanes decipiens, Aiphanes gloria and Aiphanes tatama, whose specimens were previously considered as A. parvifolia, are described here a...
Article
Full-text available
The tribe Geonomateae is a widely distributed group of 103 species of Neotropical palms which contains six ecologically important understory or subcanopy genera. Although it has been the focus of many studies, our understanding of the evolutionary history of this group, and in particular of the taxonomically complex genus Geonoma, is far from compl...
Article
Full-text available
The new species Aiphanes suaita, from the Eastern Cordillera of Colombia, is described and illustrated. Previous specimens of this species had been mistaken for Aiphanes simplex, but a molecular phylogeny revealed that it is actually more closely related to Aiphanes leiostachys, from the Central Cordillera, prompting a reexamination of the specimen...
Article
Full-text available
Ceroxylon parvum Galeano (Arecaceae) is reported in seasonally dry tropical forests (SDTF) at the localities of Oscurama, district of Bolivar, province of San Miguel; Udima in the district of Catache, and Succhapampa in the district of Pulán, province of Santa Cruz in Cajamarca, between 06°43´ S 078°57´ W and 06°57´ S 079°08´ W. The type species wa...
Article
Full-text available
Sex change is a rare event in nature. Animals and plants that change sex during their lifetime are taxonomically and geographically widespread, but comprise a small minority among Policansky (1982) sexual organisms. In dioecious plants, those in which individuals are male or female, sex change is also uncommon and has never been recorded in palms,...
Article
Full-text available
Palms hold some remarkable records, like the largest leaf of the plant kingdom in Raphia regalis (Hallé 1977) and the largest seed in Lodoicea maldivica (Dransfield et al. 2008). In fact, palms include, together with bamboos, the largest of all monocotyledons. The Andean wax palms in the genus Ceroxylon, in particular the Quindío wax palm, C. quind...
Article
Full-text available
Genetic diversity is key in providing the variation needed to face stochastic change. Increased habitat loss alters population size and dynamics posing serious threats to the conservation of wild species. Colombia has undergone massive deforestation over the last century, but harbours extraordinary high species diversity of genus Zamia (Cycadales),...
Article
Full-text available
Given the geographical complexity of the Andes, species distributions hold interesting information regarding the history of isolation and gene flow across geographic barriers and ecological gradients. Moreover, current threats to the region's enormous plant diversity pose an additional challenge to the understanding of these patterns. We explored t...
Article
Full-text available
The tropical Andes are a biodiversity hotspot, partly due to their rich and complex floristic composition. A fundamental question regarding this outstanding biodiversity is what role the Andean orogeny has played in species diversification. Ceroxylon is a genus of endemic Andean palms that stands out in the palm family (Arecaceae) due to its adapta...

Conference Paper
Zamia incognita is distributed within the Magdalena Medio region, in the Antioquia and Santander departments, Colombia. Since 2009 various activities like research, exploration and cultivation have been executed with the aim of obtaining the greatest amount of possible information, in order to elaborate an effective conservation strategy for this s...

El noroeste de América del Sur presenta una geografía sumamente compleja, con grandes contrastes y abruptos gradientes ecológicos. Este entorno es particularmente propicio para la diversificación biológica y ecológica, y la familia de las palmeras lo ilustra perfectamente, con 332 especies (142 endémicas) en la zona considerada, conformada por Colo...

Full-text available
Wax palms are an important element of the cloud forests in the tropical Andes. Despite heavy deforestation, the density of adults seems to be similar in deforested pastures as in forests. We aimed to infer the mechanisms responsible for this apparent resilience in pastures and we tested two hypotheses to explain it: 1) adult palms survived in pastu...

We studied the populations of the Quindio Wax Palm ( Ceroxylon quindiuense ) surviving in deforested areas of the upper Cocora Valley, Quindio, Colombia, by comparing photographs taken in October 1988 and December 2012 at the same sites. The seven pairs of images cover an area of ca. 26.4 hectares, corresponding to 7.4% of the deforested area of th...
