Los Andes tropicales constituyen una región única con una alta diversidad de hábitats, producto de complejos gradientes espaciales y ambientales. Los bosques montanos de esta región son considerados como una prioridad global de conservación, debido principalmente a su elevada riqueza biológica y de endemismos. Sin embargo su biodiversidad es de las menos conocidas de toda la región tropical, aunque se reconoce la amplia gama de servicios ambientales que prestan, incluyendo la regulación del clima regional y la captura y almacenamiento de carbono. Este artículo ofrece una perspectiva general del estado de conservación de los bosques montanos tropicales andinos y de los retos que esta implica. Asimismo, proporciona información sobre sus amenazas, identificando aquéllas que con mayor probabilidad sean responsables de aumentar el riesgo de extinción de especies. Se resalta la necesidad de disponer de más información sobre el estado de conservación de las especies para identificar las futuras prioridades de conservación en la región. La reciente iniciativa de la "Lista Roja y planeación para la conservación de especies de árboles montanos de los Andes Tropicales", formada por delegados de varios países de la región, constituirá una sólida base para el desarrollo y enfoque de políticas y respuestas de manejo dirigidas a la reducción de la deforestación y pérdida de especies en estos bosques, incluyendo acciones para promover la creación de áreas protegidas, restauración forestal y manejo forestal sostenible., The tropical Andes is a unique region with high habitat diversity, resulting from complex climatic and spatial gradients. Andean montane forests are currently a major global conservation priority owing to their high species richness and high level of endemism. Nonetheless they are considered one of the least known ecosystems in the tropics, but the breath of ecosystem services that these forests provide, including the regulation of regional climate and the capture and storage of carbon, is widely recognised. This article presents an overview of the conservation status of tropical Andean montane forests and the challenges it entails. It also provides information on threats, including the identification of those that are most likely to be responsible for increasing the extinction risk for many species. It highlights the need for acquiring more information on the conservation status of species as to identify future priorities for conservation in the region. The recent initiative "Red List and conservation planning for montane tree species of the Tropical Andes," made of delegates from several countries in the region, will provide a solid basis for developing policies and managing responses aimed at reducing deforestation and species loss in these forests, including actions to promote the creation of protected areas, forest restoration and sustainable forest management., Bournemouth University, Botanic Gardens Conservation International, Banco Santander

- Abstract
Background: A discussion on social media led to the formation of a multidisciplinary group working on this project to highlight women's contributions to science. The role of marginalised groups in science has been a topic of much discussion, but data on these contributions are largely lacking. Our motivation for the development of this dataset was not only to highlight names of plant genera that honour women, but to enrich this information with data that would allow the names, roles and lives of these women to be shared more widely with others, both researchers and data sources like Wikidata. Amplification of the contributions of women to botany through multiple means will enable the community to better recognise and celebrate the role of this particular marginalised group in the history and development of science., New Information: The innovative approach of our study resulted in a dataset that is dynamic, expansive and widely shared. We have published a static dataset with this paper and have also created a dynamic dataset by linking flowering plant genera and the women in whose honour those genera were named in Wikidata. This concurrent addition of the data to Wikidata, a linked open data repository, enabled it to be enriched, queried and proactively shared during the whole process of dataset creation and into the future. This innovative workflow allowed wide, open participation throughout the research process. The methodology and workflows applied can be used to create future datasets celebrating and amplifying the contributions of marginalised groups in science., (Sabine von Mering, Lauren Maria Gardiner, Sandra Knapp, Heather Lindon, Siobhan Leachman, Carmen Ulloa Ulloa, Sarah Vincent, Maria S.

- Abstract
Amazonian environments are being degraded by modern industrial and agricultural activities at a pace far above anything previously known, imperiling its vast biodiversity reserves and globally important ecosystem services. The most substantial threats come from regional deforestation, because of export market demands, and global climate change. The Amazon is currently perched to transition rapidly from a largely forested to a nonforested landscape. These changes are happening much too rapidly for Amazonian species, peoples, and ecosystems to respond adaptively. Policies to prevent the worst outcomes are known and must be enacted immediately. We now need political will and leadership to act on this information. To fail the Amazon is to fail the biosphere, and we fail to act at our peril.

- Abstract
Field photographs of plant species are crucial for research and conservation, but the lack of a centralized database makes them difficult to locate. We surveyed 25 online databases of field photographs and found that they harboured only about 53% of the approximately 125,000 vascular plant species of the Americas. These results reflect the urgent need for a centralized database that can both integrate and complete the photographic record of the world's flora., (© 2021.

- Abstract
We compare the numbers of vascular plant species in the three major tropical areas. The Afrotropical Region (Africa south of the Sahara Desert plus Madagascar), roughly equal in size to the Latin American Region (Mexico southward), has only 56,451 recorded species (about 170 being added annually), as compared with 118,308 recorded species (about 750 being added annually) in Latin America. Southeast Asia, only a quarter the size of the other two tropical areas, has approximately 50,000 recorded species, with an average of 364 being added annually. Thus, Tropical Asia is likely to be proportionately richest in plant diversity, and for biodiversity in general, for its size. In the animal groups we reviewed, the patterns of species diversity were mostly similar except for mammals and butterflies. Judged from these relationships, Latin America may be home to at least a third of global biodiversity., (Copyright © 2020 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

- Abstract
We compiled a data set for all tree species collected to date in lowland Amazonian Ecuador in order to determine the number of tree species in the region. This data set has been extensively verified by taxonomists and is the most comprehensive attempt to evaluate the tree diversity in one of the richest species regions of the Amazon. We used four main sources of data: mounted specimens deposited in Ecuadorian herbaria only, specimen records of a large-scale 1-hectare-plot network (60 plots in total), data from the Missouri Botanical Garden Tropicos® database (MO), and literature sources. The list of 2,296 tree species names we provide in this data set is based on 47,486 herbarium records deposited in the following herbaria: Alfredo Paredes Herbarium (QAP), Catholic University Herbarium (QCA), Herbario Nacional del Ecuador (QCNE), Missouri Botanical Garden (MO), and records from an extensive sampling of 29,768 individuals with diameter at breast height (dbh) ≥10 cm recorded in our plot network. We also provide data for the relative abundance of species, geographic coordinates of specimens deposited in major herbaria around the world, whether the species is native or endemic, current hypothesis of geographic distribution, representative collections, and IUCN threat category for every species recorded to date in Amazonian Ecuador. These data are described in Metadata S1 and can be used for macroecological, evolutionary, or taxonomic studies. There are no copyright restrictions; data are freely available for noncommercial scientific use (CC BY 3.0).

- Abstract
The cataloging of the vascular plants of the Americas has a centuries-long history, but it is only in recent decades that an overview of the entire flora has become possible. We present an integrated assessment of all known native species of vascular plants in the Americas. Twelve regional and national checklists, prepared over the past 25 years and including two large ongoing flora projects, were merged into a single list. Our publicly searchable checklist includes 124,993 species, 6227 genera, and 355 families, which correspond to 33% of the 383,671 vascular plant species known worldwide. In the past 25 years, the rate at which new species descriptions are added has averaged 744 annually for the Americas, and we can expect the total to reach about 150,000., (Copyright © 2017 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

- Abstract
A new species from Ecuador, Symplocos limonensis, is here described and illustrated. It resembles Symplocos clethrifolia but differs by having larger leaves with evident (i.e., not concealed) areoles on lower surface, sessile inflorescences, smaller white corollas, and fewer stamens. The species is only known from three collections in the Andean forests of Morona-Santiago Province in southern Ecuador.
