Species are seen as the fundamental unit of biotic diversity, and thus their delimitation is crucial for defining measures for diversity assessments and studying evolution. Differences between species have traditionally been associated with variation in morphology. And yet, the discovery of cryptic diversity suggests that the evolution of distinct...
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...
Aim: To disentangle the influence of environmental factors at different spatial grains (regional and local) on fern and lycophyte species richness and ask how regional and plot-level richness are related to each other.
Location: Global.
Time period: Present.
Major Taxa studied: Ferns and lycophytes.
Methods: We explored fern and lycophyte species r...
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...
In the scope of pantropical studies aimed at understanding how the diversity of grammitid ferns (Polypodiaceae) has evolved and is maintained, we studied a diverse grammitid community in treeline elfin forests in eight study plots of 400 m2 each at 3200 m on Cerro Toledo, Loja, southern Ecuador. We recorded a total of 7986 individuals of 16 grammit...
Is there a maximum number of species that can coexist? Intuitively, we assume an upper limit to the number of species in a given assemblage, or that a lineage can produce, but defining and testing this limit has proven problematic. Herein, we first outline seven general challenges of studies on species saturation, most of which are independent of t...
El Parque Nacional Natural Sierra Nevada del Cocuy (PNN Cocuy) exhibe la mayor extensión de glaciares en Colombia y elevaciones que alcanzan los 5330 m. La Sierra es una de las fuentes de agua más importantes del país, pues alberga numerosos lagos, ríos y quebradas. Aunque sabemos que el calentamiento global está causando el derretimiento de los gl...
The palm cabecinegro (Manicaria saccifera) is one of the most representative species of flooded palm groves in the center of the department of Chocó. The production of handicrafts from the peduncular bracts that cover the inflorescences is an important activity for the economy of some local communities. In this chapter we describe the habitat, aspe...
Are the hyperdiverse local forests of the western Amazon undergoing changes linked to global and local drivers such as climate change, or successional dynamics? We analyzed local climatic records to assess potential climatic changes in Yasuní National Park, Ecuador, and compared two censuses (1995, 2012) of a palm community to assess changes in com...
Climate change is strong in the Amazon basin. Climate models consistently predict widespread warmer and drier conditions by the end of the 21st century. As a consequence, water stress will increase throughout the region. We here review current understanding of the impact of climate change on forests' distribution patterns, species diversity and eco...
En el valle seco del río Magdalena en Colombia se cosechan las hojas de la palma de vino (Attalea butyracea) para la comercialización. Los cogollos son usados como Ramo Bendito durante la Semana Santa, y las hojas expandidas para la construcción de techos y de artículos artesanales. Con el fin de documentar la producción de hojas y evaluar el efect...
Attalea butyracea (Mutis ex L.f.) Wess. Boer is a massive and abundant palm that grows in dry areas of northern, central and eastern Colombia, where it ranks as one of the most useful plants. Thirty-six uses in eight use categories are recorded for this species in Colombia, including food, animal feed, medicine, construction, and technological and...
