Chevalier, M. (2019). Enabling possibilities to quantify past climate from fossil assemblages at a global scale. Global and Planetary Change, 175, 27–35. doi:10.1016/j.gloplacha.2019.01.016 https://doi.org/10.1016/j.gloplacha.2019.01.016

The field of quantitative palaeoclimatology has made significant progress in the past decades. However, this progress has been spatially heterogeneous and strong discrepancies – both in terms of quality and density – exist between Europe and North America and the rest of the world. The need to balan…

Sheppard, C. S., & Schurr, F. M. (2018). Biotic resistance or introduction bias? Immigrant plant performance decreases with residence times over millennia. Global Ecology and Biogeography. doi:10.1111/geb.12844 https://doi.org/10.1111/geb.12844

Aim: Invasions are dynamic processes. Invasive spread causes the geographical range size of alien species to increase with residence time. However, with time native competitors and antagonists can adapt to invaders. This build‐up of biotic resistance may eventually limit the invader’s performance an…

Crespo-Mendes, N., Laurent, A., & Hauschild, M. Z. (2018). Effect factors of terrestrial acidification in Brazil for use in Life Cycle Impact Assessment. The International Journal of Life Cycle Assessment. doi:10.1007/s11367-018-1560-7 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., Laurent, A., Bruun, H. H., & Hauschild, M. Z. (2019). Relationships between plant species richness and soil pH at the level of biome and ecoregion in Brazil. Ecological Indicators, 98, 266–275. doi:10.1016/j.ecolind.2018.11.004 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…

Wan, J.-Z., Wang, C.-J., & Yu, F.-H. (2019). Large-scale environmental niche variation between clonal and non-clonal plant species: Roles of clonal growth organs and ecoregions. Science of The Total Environment, 652, 1071–1076. doi:10.1016/j.scitotenv.2018.10.280 https://doi.org/10.1016/j.scitotenv.2018.10.280

Clonal plant species can produce genetically identical and potentially independent offspring, and dominate a variety of habitats. The divergent evolutionary mechanisms between clonal and non-clonal plants are interesting areas of ecological research. A number of studies have shown that the environme…

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…

Moreira, T. C. L., Amato-Lourenço, L. F., da Silva, G. T., Saldiva de André, C. D., de André, P. A., Barrozo, L. V., … Locosselli, G. M. (2018). The Use of Tree Barks to Monitor Traffic Related Air Pollution: A Case Study in São Paulo–Brazil. Frontiers in Environmental Science, 6. doi:10.3389/fenvs.2018.00072 https://doi.org/10.3389/fenvs.2018.00072

The analysis of chemical elements in the barks of trees is an alternative procedure to access spatial heterogeneity of traffic related air pollution. However, the role of tree species in the characterization of the variability of airborne pollution is poorly known. We present an observational study …

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…

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…

Reichgelt, T., West, C. K., & Greenwood, D. R. (2018). The relation between global palm distribution and climate. Scientific Reports, 8(1). doi:10.1038/s41598-018-23147-2 https://doi.org/10.1038/s41598-018-23147-2

Fossil palms provide qualitative evidence of (sub-) tropical conditions and frost-free winters in the geological past, including modern cold climate regions (e.g., boreal, or polar climates). The freeze intolerance of palms varies across different organs and life stages, with seedlings in particular…
