Klages, J. P., U. Salzmann, T. Bickert, C.-D. Hillenbrand, K. Gohl, G. Kuhn, et al. 2020. Temperate rainforests near the South Pole during peak Cretaceous warmth. Nature 580: 81–86. https://doi.org/10.1038/s41586-020-2148-5

The mid-Cretaceous period was one of the warmest intervals of the past 140 million years1,2,3,4,5, driven by atmospheric carbon dioxide levels of around 1,000 parts per million by volume6. In the near absence of proximal geological records from south of the Antarctic Circle, it is disputed whether p…

Ringelberg, J. J., N. E. Zimmermann, A. Weeks, M. Lavin, and C. E. Hughes. 2020. Biomes as evolutionary arenas: Convergence and conservatism in the trans‐continental succulent biome A. Moles [ed.],. Global Ecology and Biogeography 29: 1100–1113. https://doi.org/10.1111/geb.13089

Aim: Historically, biomes have been defined based on their structurally and functionally similar vegetation, but there is debate about whether these similarities are superficial, and about how biomes are defined and mapped. We propose that combined assessment of evolutionary convergence of plant fun…

Moudrý, V., and R. Devillers. 2020. Quality and usability challenges of global marine biodiversity databases: An example for marine mammal data. Ecological Informatics 56: 101051. https://doi.org/10.1016/j.ecoinf.2020.101051

Knowing spatial and temporal patterns of species distribution is paramount to support marine species persistence. While datasets provided by global aggregators are increasingly rich and useful, they suffer from various types of data quality issues that can impact their usage. Using marine mammals as…

Mezghani, N., C. K. Khoury, D. Carver, H. A. Achicanoy, P. Simon, F. M. Flores, and D. Spooner. 2019. Distributions and Conservation Status of Carrot Wild Relatives in Tunisia: A Case Study in the Western Mediterranean Basin. Crop Science 59: 2317–2328. https://doi.org/10.2135/cropsci2019.05.0333

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant species, are sources of valuable genetic resources for crop improvement. Persisting gaps in knowledge of taxonomy, distributions, and characterization for traits of interest constrain their expanded use in plan…

Folk, R. A., R. L. Stubbs, M. E. Mort, N. Cellinese, J. M. Allen, P. S. Soltis, D. E. Soltis, and R. P. Guralnick. 2019. Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences 116: 10874–10882. https://doi.org/10.1073/pnas.1817999116

Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. Such density-dependent models imply tight linkages between diversification and…

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…

Sheppard, C. S., and F. M. Schurr. 2018. Biotic resistance or introduction bias? Immigrant plant performance decreases with residence times over millennia. Global Ecology and Biogeography. 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…

Peterson, A. T., A. Asase, D. Canhos, S. de Souza, and J. Wieczorek. 2018. Data Leakage and Loss in Biodiversity Informatics. Biodiversity Data Journal 6. https://doi.org/10.3897/bdj.6.e26826

The field of biodiversity informatics is in a massive, “grow-out” phase of creating and enabling large-scale biodiversity data resources. Because perhaps 90% of existing biodiversity data nonetheless remains unavailable for science and policy applications, the question arises as to how these existin…

Antonelli, A., A. Zizka, F. A. Carvalho, R. Scharn, C. D. Bacon, D. Silvestro, and F. L. Condamine. 2018. Amazonia is the primary source of Neotropical biodiversity. Proceedings of the National Academy of Sciences 115: 6034–6039. 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…
