Abstract Aim We combine phylogenetic and point locality data from selected lineages of the Atlantic Forest flora fauna to compare spatial patterns biodiversity sustained by current configuration forest remnants a scenario complete preservation. then ask question "how much is likely lost, already"? Specifically, we assess how habitat loss impacted climatic spaces occupied local species, inferred composition communities distribution diversity endemism. Location Forest, Brazil. Methods Using...
Abstract Phylogenomics enhances our understanding of plant radiations in the biodiverse Andes. Our study focuses on Puya , primarily Andean and a part Bromeliaceae family. Using phylogenomic framework based Angiosperms353 probe set for 80 species, we explored ′s phenotypic evolution biogeography. Divergence time analyses ancestral area estimations suggested that originated Central Coastal Chile around 9 million years ago (Ma). Subsequently, it dispersed to dry valleys Andes Puna regions...
The Orchidaceae family is one of the most diverse within Angiosperms, and Epidendrum its largest genera. A new species this genus, rasmussenii, here illustrated, described, compared with morphological geographically similar species. This was found in a cloud forest Sierra Nevada de Santa Marta (SNSM) Colombian Caribbean. It to stenostachyum but differing by red-carmin yellow-green flowers yellowish green towards apex sepals petals (vs. yellow-green, spotted purple flowers), 5.6 × 0.4 mm,...
Abstract Aim There is little consensus on which environmental variables are best at predicting multiple dimensions of diversity. We ask whether there common correlates diversity, despite ecological differences, across nine clades plants and animals distributed along a single rainforest domain. For that, we compare the species richness, phylogenetic endemism. Location Brazilian Atlantic Forest. Taxon: Five (Bromelioideae, Miconieae, Bertolonia , Cambessedesieae, Fridericia allies) four...
A phylogenetic study testing the monophyly of geographically disjunct genus Ronnbergia (Bromeliaceae, Bromelioideae) is presented. The analyses were based on taxon sampling that included all but one species Ronnbergia, and representative lineages across subfamily Bromelioideae. Three chloroplast DNA sequence markers (matK, psbA-trnH, trnL-trnF) morphological data used for reconstruction. Both molecular datasets supported polyphyly either independently or in combination. These findings...
Generic status for the Amazonian Hylaeaicum is proposed within Aechmea alliance, excluding it from “Nidularioid complex” in general and Neoregelia particular. The monophyly of this new genus supported by molecular phylogenetic analyses. taxonomic circumscription based on combination geographical range morphological characters, such as clonal growth, inflorescence structure, petal corolla conformation, appendages, ovary, ovule, stigma, pollen, fruit, seed, well seed anatomy, thoroughly...
Abstract The Ronnbergia alliance is a lineage of two genera, and Wittmackia, which diversified in three centres distribution; the Pacific Forest, Atlantic Forest Caribbean. In this study, we reconstructed most plausible biogeographic scenario that explain disjunct evolution these diversity. We also compared evolutionary rate dynamics diversification floral each areas. Our results suggested originated c. 5.2 Mya. 3.5 Mya after long-distance dispersal event to Forest. Wittmackia started 3.2...
Abstract Two new species and a combination for Steyerbromelia (Bromeliaceae: Navioideae) are presented. These novelties represent the first records of Colombia. The species, naquenensis nukakii, were placed in based on their 3- or 4-divided inflorescences, presence smooth posterior sepals, ovate, shortappendaged ovules. Both resemble each other S. thomasii, which also occurs basin Upper Rio Negro. garcia-barrigae is transferred from Navia, despite lack petal appendages, because its...

A bstract The Andes are a hotspot for biodiversity and high species endemism both plants animals. genus Puya (Bromeliaceae) lives throughout the Andes, including puna páramo ecosystems above 3500m. Here, we studied life history reproductive size thresholds in three of ( P. raimondii, cryptantha goudotiana ): raimondii Bolivian puna, Colombian páramo. We collected data on threshold at flowering clonal reproduction. All were found to have consistent minimum flowering, while only demonstrated...
Completar la Lista Roja de las Plantas Colombia es una metas principales Estrategia Nacional para Conservación (ENCP) y crucial planificación conservación flora del país. La serie Libro Rojo realizó primera contribución importante a nacional, desde el 2014 un equipo trabajo asociado ENCP Grupo Especialistas (GEPC) UICN han coordinado esfuerzos seguir avanzando en esta tarea. Al final 2022 nivel nacional alcanzó 12 % cobertura especies reportadas país año 2025 alcanzará al menos 25 %. Según...
A taxonomic revision of the 17 Caribbean-endemic species Wittmackia (Bromeliaceae) is presented. This group a monophyletic lineage previously circumscribed as Hohenbergia subg. Wittmackiopsis but later transferred to based on phylogenetic and morphological evidence. treatment includes complete overview variation species, their geographical distribution habitat, notes ecology conservation. key for identification provided. Finally, descriptions with comments taxonomy, geographic habitat are
Recent botanical expeditions to the Dolphin Head Mountains in western Jamaica allowed collection of different specimens a new species, Hohenbergia rohan-estyi, an enigmatic plant that resembles also Jamaican-endemic H. negrilensis. In this study, we describe rohan-estyi and include notes on its geographical distribution, habitat, conservation status taxonomy. The length stipes number flowers per spike permit differentiation from addition, geographic distributions these two species do not...
A new species of Tillandsia from high elevation forests the Eastern Cordillera Colombia is described here: chingacensis. This unique because its floral parts densely covered with a resin-like substance, and exceptionally long fruits. Although this has distichous flowers bears petal appendages, it was not placed in Vriesea shows morphological affinities to subg. Allardtia, suggesting better placement taxon Tillandsia. The discovery result recent explorations former war zone proximity Bogotá...
