Ureta, C., Cuervo-Robayo, Á. P., Calixto-Pérez, E., González-Salazar, C., … Fuentes-Conde, E. (2018). A first approach to evaluate the vulnerability of islands’ vertebrates to climate change in Mexico. Atmósfera, 31(3), 251–254. doi:10.20937/atm.2018.31.03.03 https://doi.org/10.20937/ATM.2018.31.03.03

Mexican islands are one of the most diverse territories in the world and consequently their conservation should be a national and international priority. Three main threats to islands’ diversity have been detected: invasive species, land use change and climate change. Most studies have been focused …

Antonelli, A., Zizka, A., Carvalho, F. A., Scharn, R., Bacon, C. D., Silvestro, D., & Condamine, F. L. (2018). Amazonia is the primary source of Neotropical biodiversity. Proceedings of the National Academy of Sciences, 115(23), 6034–6039. doi:10.1073/pnas.1713819115 https://doi.org/10.1073/pnas.1713819115

The American tropics (the Neotropics) are the most species-rich realm on Earth, and for centuries, scientists have attempted to understand the origins and evolution of their biodiversity. It is now clear that different regions and taxonomic groups have responded differently to geological and climati…

VÁZQUEZ-GARCÍA, J.-A., NEILL, D. A., SHALISKO, V., ARROYO, F., & MERINO-SANTI, R. E. (2018). Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution. Phytotaxa, 348(4), 254. doi:10.11646/phytotaxa.348.4.2 https://doi.org/10.11646/phytotaxa.348.4.2

Magnolia mercedesiarum, a new species from the eastern slopes of the Andes in northern Ecuador, is described and illustrated, and a key to Ecuadorian Magnolia (subsect. Talauma) is provided. This species differs from M. vargasiana in having broadly elliptic leaves that have an obtuse base vs. suborb…

Wan, J.-Z., & Wang, C.-J. (2018). Expansion risk of invasive plants in regions of high plant diversity: A global assessment using 36 species. Ecological Informatics, 46, 8–18. doi:10.1016/j.ecoinf.2018.04.004 https://doi.org/10.1016/j.ecoinf.2018.04.004

Invasive plant species (IPS) have a high potential for expanding within biodiversity hotspots and threatening global plant diversity. Hence, it is urgent to assess the expansion risk of IPS in regions of high plant diversity and their potentially negative effects throughout the world. We used the wo…

Yañez-Arenas, C., Díaz-Gamboa, L., Patrón-Rivero, C., López-Reyes, K., & Chiappa-Carrara, X. (2018). Estimating geographic patterns of ophidism risk in Ecuador. Neotropical Biodiversity, 4(1), 55–61. doi:10.1080/23766808.2018.1454762 https://doi.org/10.1080/23766808.2018.1454762

The species richness of venomous snakes in Ecuador (~39 species) is among the highest in the world. However, until now no information exists regarding geographic patterns of ophidism. In this study, we present a detailed spatial snakebite risk map which was built by stacking weighted ecological nich…

Petersen, K. B., & Burd, M. (2018). The adaptive value of heterospory: Evidence from Selaginella . Evolution, 72(5), 1080–1091. doi:10.1111/evo.13484 https://doi.org/10.1111/evo.13484

Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. We used the geographic distributions of 114 species of the heterosporous lycophyte Selaginella to explore the functional ecology of microspore and megaspore size, traits that would be corre…

Faurby, S., & Araújo, M. B. (2018). Anthropogenic range contractions bias species climate change forecasts. Nature Climate Change, 8(3), 252–256. doi:10.1038/s41558-018-0089-x https://doi.org/10.1038/s41558-018-0089-x

Forecasts of species range shifts under climate change most often rely on ecological niche models, in which characterizations of climate suitability are highly contingent on the species range data used. If ranges are far from equilibrium under current environmental conditions, for instance owing to …

Sundue, M. A. (2017). Ceradenia spectabilis (Polypodiaceae), a New Species from Cerro del Torrá, Colombia. American Fern Journal, 107(4), 193–199. doi:10.1640/0002-8444-107.4.193 https://doi.org/10.1640/0002-8444-107.4.193

Ceradenia spectabilis, a new species, is described from Cerro del Torrá, an isolated peak in western Colombia well known for harboring rare and narrowly distributed species of plants. The new species is readily distinguished from its congeners by its broadly alate petiole and rachis, creeping rhizom…
