Karger, D. N., M. Kessler, O. Conrad, P. Weigelt, H. Kreft, C. König, and N. E. Zimmermann. 2019. Why tree lines are lower on islands—Climatic and biogeographic effects hold the answer J. Grytnes [ed.],. Global Ecology and Biogeography 28: 839–850. https://doi.org/10.1111/geb.12897

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…

Oleas, N., K. Feeley, J. Fajardo, A. Meerow, J. Gebelein, and J. Francisco-Ortega. 2019. Muddy Boots Beget Wisdom: Implications for Rare or Endangered Plant Species Distribution Models. Diversity 11: 10. https://doi.org/10.3390/d11010010

Species distribution models (SDMs) are popular tools for predicting the geographic ranges of species. It is common practice to use georeferenced records obtained from online databases to generate these models. Using three species of Phaedranassa (Amaryllidaceae) from the Northern Andes, we compare t…

Crespo-Mendes, N., A. Laurent, and M. Z. Hauschild. 2018. Effect factors of terrestrial acidification in Brazil for use in Life Cycle Impact Assessment. The International Journal of Life Cycle Assessment 24: 1105–1117. https://doi.org/10.1007/s11367-018-1560-7

Purpose:In Life Cycle Impact Assessment, atmospheric fate factors, soil exposure factors, and effect factors are combined to characterize potential impacts of acidifying substances in terrestrial environments. Due to the low availability of global data sets, effect factors (EFs) have been reported a…

Crespo-Mendes, N., A. Laurent, H. H. Bruun, and M. Z. Hauschild. 2019. Relationships between plant species richness and soil pH at the level of biome and ecoregion in Brazil. Ecological Indicators 98: 266–275. https://doi.org/10.1016/j.ecolind.2018.11.004

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…

VÁZQUEZ-GARCÍA, J.-A., D. A. NEILL, V. SHALISKO, F. ARROYO, and R. E. MERINO-SANTI. 2018. Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution. Phytotaxa 348: 254. 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…
