Milla, R., Bastida, J. M., Turcotte, M. M., Jones, G., Violle, C., Osborne, C. P., … Byun, C. (2018). Phylogenetic patterns and phenotypic profiles of the species of plants and mammals farmed for food. Nature Ecology & Evolution, 2(11), 1808–1817. doi:10.1038/s41559-018-0690-4 https://doi.org/10.1038/s41559-018-0690-4

The origins of agriculture were key events in human history, during which people came to depend for their food on small numbers of animal and plant species. However, the biological traits determining which species were domesticated for food provision, and which were not, are unclear. Here, we invest…

Hoffmann, W. A., Flake, S. W., Abreu, R. C. R., Pilon, N. A. L., Rossatto, D. R., & Durigan, G. (2018). Rare frost events reinforce tropical savanna–forest boundaries. Journal of Ecology, 107(1), 468–477. doi:10.1111/1365-2745.13047 https://doi.org/10.1111/1365-2745.13047

1.The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be important for maintaining savanna, particularly at the edge of the tropics. 2…

Park, D. S., & Razafindratsima, O. H. (2018). Anthropogenic threats can have cascading homogenizing effects on the phylogenetic and functional diversity of tropical ecosystems. Ecography, 42(1), 148–161. doi:10.1111/ecog.03825 https://doi.org/10.1111/ecog.03825

Determining the mechanisms that underlie species distributions and assemblages is necessary to effectively preserve biodiversity. This cannot be accomplished by examining a single taxonomic group, as communities comprise a plethora of interactions across species and trophic levels. Here, we examine …

Joffard, N., Massol, F., Grenié, M., Montgelard, C., & Schatz, B. (2018). Effect of pollination strategy, phylogeny and distribution on pollination niches of Euro‐Mediterranean orchids. Journal of Ecology, 107(1), 478–490. doi:10.1111/1365-2745.13013 https://doi.org/10.1111/1365-2745.13013

1.Pollination niches are important components of ecological niches and have played a major role in the diversification of Angiosperms. In this study, we focused on Euro‐Mediterranean orchids, which use diverse pollination strategies and interact with various functional groups of insects. In these or…

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…

Schley, R. J., de la Estrella, M., Pérez-Escobar, O. A., Bruneau, A., Barraclough, T., Forest, F., & Klitgård, B. (2018). Is Amazonia a “museum” for Neotropical trees? The evolution of the Brownea clade (Detarioideae, Leguminosae). Molecular Phylogenetics and Evolution, 126, 279–292. doi:10.1016/j.ympev.2018.04.029 https://doi.org/10.1016/j.ympev.2018.04.029

The flora of the Neotropics is unmatched in its diversity, however the mechanisms by which diversity has accumulated are debated and largely unclear. The Brownea clade (Leguminosae) is a characteristic component of the Neotropical flora, and the species within it are diverse in their floral morpholo…

Pérez Navarro, M. Á., Sapes, G., Batllori, E., Serra-Diaz, J. M., Esteve, M. A., & Lloret, F. (2018). Climatic Suitability Derived from Species Distribution Models Captures Community Responses to an Extreme Drought Episode. Ecosystems. doi:10.1007/s10021-018-0254-0 https://doi.org/10.1007/s10021-018-0254-0

The differential responses of co-occurring species in rich communities to climate change—particularly to drought episodes—have been fairly unexplored. Species distribution models (SDMs) are used to assess changes in species suitability under environmental shifts, but whether they can portray populat…

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 …

Grossenbacher, D. L., Brandvain, Y., Auld, J. R., Burd, M., Cheptou, P.-O., Conner, J. K., … Goldberg, E. E. (2017). Self-compatibility is over-represented on islands. New Phytologist, 215(1), 469–478. doi:10.1111/nph.14534 https://doi.org/10.1111/nph.14534

Because establishing a new population often depends critically on finding mates, individuals capable of uniparental reproduction may have a colonization advantage. Accordingly, there should be an over-representation of colonizing species in which individuals can reproduce without a mate, particularl…
