Petersen, K. B., and M. Burd. 2018. The adaptive value of heterospory: Evidence from Selaginella. Evolution 72: 1080–1091. 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…

Background: Epeoloides pilosulus, one of the rarest bees in North America, is a cleptoparasite of Macropis bees which themselves are uncommon oligoleges of oil-producing Lysimachia flowers. Only two specimens of the cleptoparasite have been reported from Canada since the 1960s, both from Nova Scotia…

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 …

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…
Manchego, C. E., P. Hildebrandt, J. Cueva, C. I. Espinosa, B. Stimm, and S. Günter. 2017. Climate change versus deforestation: Implications for tree species distribution in the dry forests of southern Ecuador R. Zang [ed.],. PLOS ONE 12: e0190092. https://doi.org/10.1371/journal.pone.0190092
Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted. This study aims to quantify and compare the effects of deforestation and climate change on the natural spatial range…
Guedes, T. B., R. J. Sawaya, A. Zizka, S. Laffan, S. Faurby, R. A. Pyron, R. S. Bérnils, et al. 2017. Patterns, biases and prospects in the distribution and diversity of Neotropical snakes. Global Ecology and Biogeography 27: 14–21. https://doi.org/10.1111/geb.12679
Motivation: We generated a novel database of Neotropical snakes (one of the world’s richest herpetofauna) combining the most comprehensive, manually compiled distribution dataset with publicly available data. We assess, for the first time, the diversity patterns for all Neotropical snakes as well as…

Two types of fossil Terminalia (Combretaceae) fruits are described from warmer periods in New Zealand’s past. One is represented by large ‘fin-winged’ fruit (samara) from the Early Miocene Manuherikia Group sediments of Bannockburn and the Nevis Valley. The form and size of the fruits are entirely u…

The persistence of traditional cultures and modes of land use within rapidly changing, globalized societies is a central issue in understanding ecological and cultural change in the Anthropocene. Located in the heart of the Green Revolution, the Yoreme (Mayo) people of the Mayo Valley in Mexico stil…

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…
