A large-scale phylogeny of polygonaceae based on molecular data
Few studies have addressed the evolutionary relationships within Polygonaceae from a global perspective. The convoluted taxonomic history of Polygonaceae is a major barrier to understanding evolution in this group, and ...

Effects of cumulus clouds on microclimate and shoot-level photosynthetic gas exchange in Picea engelmannii and Abies lasiocarpa at treeline, Medicine Bow Mountains, Wyoming, USA
Here we describe the dynamic effects of cumulus clouds on microclimate and shoot-level photosynthetic gas exchange in saplings of two treeline conifer species—Picea engelmannii and Abies lasiocarpa. Measurements were made ... Artículo. 2015

Fidelity and promiscuity in an ant-plant mutualism : A case study of Triplaris and Pseudomyrmex
The association between the myrmecophyte Triplaris and ants of the genus Pseudomyrmex is an often-reported example of mutualism but no molecular studies have examined this association to date. In this study, the interspecific ...

Neotropical ant-plant Triplaris americana attracts Pseudomyrmex mordax ant queens during seedling stages
The association between the myrmecophyte Triplaris and ants of the genus Pseudomyrmex is an often-reported example of mutualism in the Neotropics. The ants colonize the hollow stems of their hosts, and in exchange, the ... Artículo. 2017

Phylogenetic relationships of Triplaris and Ruprechtia: Re-delimitation of the recognized genera and two new genera for tribe Triplarideae (Polygonaceae)
Recent phylogenetic work has increased our knowledge of the relationships within Polygonaceae. However, few studies have explored the generic relationships within Eriogonoideae. Two understudied genera are Triplaris and ... Artículo. 2011

Phylogenetics of Polygonaceae with an emphasis on the evolution of Eriogonoideae
Polygonaceae has long been recognized as a monophyletic family but the circumscription of groups within it has been in constant flux. Two groups currently recognized are the subfamilies Eriogonoideae and Polygonoideae. An ... Artículo. 2008

Protection against herbivory in the mutualism between Pseudomyrmex dendroicus (Formicidae) and Triplaris americana (Polygonaceae)
Herbivory significantly impacts the growth and reproduction of plants. Many plants have developed ways to defend against herbivores and one common strategy is to associate with ants. In many ant-plant interactions, ants ... Artículo. 2015

Revised subfamily classification for Polygonaceae, with a tribal classification for Eriogonoideae
Recent phylogenetic studies have provided a revised hypothesis of the evolutionary relationships within Polygonaceae, particularly regarding placement of certain tropical taxa. Based on phylogenetic data, we recognize three ... Artículo. 2011

Taxonomy of Polygonoideae (Polygonaceae): A new tribal classification
The subfamily Polygonoideae has a world-wide distribution and is an important component of many countries' floras. In this study we present the most comprehensive sampling available to date, including data from three ... Artículo. 2011

The ecology of peace: preparing Colombia for new political and planetary climates
"Colombia, one of the world's most species-rich nations, is currently undergoing a profound social transition: the end of a decades-long conflict with the Revolutionary Armed Forces of Colombia, known as FARC. The peace ... Artículo. 2018

Woody vegetation dynamics in the tropical and subtropical Andes from 2001 to 2014: Satellite image interpretation and expert validation
"The interactions between climate and land-use change are dictating the distribution of flora and fauna and reshuffling biotic community composition around the world. Tropical mountains are particularly sensitive because ... Artículo. 2019
