Soil pH has been used to indicate how changes in soil acidity can influence species loss. The correlation between soil pH and plant species richness has mainly been studied in North America and Europe, while there is a lack of studies exploring Tropical floras. Here, our aim was therefore to investi…

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…

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…

Jurd, D., & Pole, M. (2017). Miocene “fin-winged” fruits and Pliocene drift fruits – the first record of Combretaceae (Terminalia) from New Zealand. Geobios, 50(5-6), 423–429. doi:10.1016/j.geobios.2017.10.002 https://doi.org/10.1016/j.geobios.2017.10.002

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…
