Stull, G., Tiffney, B. H., Manchester, S. R., Rio, C. D., & Wing, S. L. (2019). Endocarps of Pyrenacantha (Icacinaceae) from the early Oligocene of Egypt. International Journal of Plant Sciences. doi:10.1086/706854 https://doi.org/10.1086/706854

The fossil record of Pyrenacantha (Phytocreneae tribe, Icacinaceae) includes well-documented species from the Paleogene of North and South America but, to date, no fossils have been described from its present geographic range, the Old World tropics. We document endocarp remains from the early Oligoc…

Marconi, L., & Armengot, L. (2020). Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment, 287, 106664. doi:10.1016/j.agee.2019.106664 https://doi.org/10.1016/j.agee.2019.106664

In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…

Fletcher, T. L., Warden, L., Sinninghe Damsté, J. S., Brown, K. J., Rybczynski, N., Gosse, J. C., & Ballantyne, A. P. (2019). Evidence for fire in the Pliocene Arctic in response to amplified temperature. Climate of the Past, 15(3), 1063–1081. doi:10.5194/cp-15-1063-2019 https://doi.org/10.5194/cp-15-1063-2019

The mid-Pliocene is a valuable time interval for investigating equilibrium climate at current atmospheric CO2 concentrations because atmospheric CO2 concentrations are thought to have been comparable to the current day and yet the climate and distribution of ecosystems were quite different. One intr…

Pietras, M. (2019). First record of North American fungus Rhizopogon pseudoroseolus in Australia and prediction of its occurrence based on climatic niche and symbiotic partner preferences. Mycorrhiza. doi:10.1007/s00572-019-00899-x https://doi.org/10.1007/s00572-019-00899-x

In 2017 a North American fungus, Rhizopogon pseudoroseolus (Boletales, Basidiomycota), formerly known in Oceania as only occurring in New Zealand, was found for the first time in South Australia. The morphological identification of collected specimens was confirmed using an internal transcribed spac…

Folk, R. A., Stubbs, R. L., Mort, M. E., Cellinese, N., Allen, J. M., Soltis, P. S., … Guralnick, R. P. (2019). Rates of niche and phenotype evolution lag behind diversification in a temperate radiation. Proceedings of the National Academy of Sciences, 116(22), 10874–10882. doi:10.1073/pnas.1817999116 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…

Capinha, C. (2019). Predicting the timing of ecological phenomena using dates of species occurrence records: a methodological approach and test case with mushrooms. International Journal of Biometeorology. doi:10.1007/s00484-019-01714-0 https://doi.org/10.1007/s00484-019-01714-0

Spatiotemporal predictions of ecological phenomena are highly useful and significant in scientific and socio-economic applications. However, the inadequate availability of ecological time-series data often impedes the development of statistical predictions. On the other hand, considerable amounts of…

Rotllan-Puig, X., & Traveset, A. (2019). Determining the Minimal Background Area for Species Distribution Models: MinBAR Package. doi:10.1101/571182 https://doi.org/10.1101/571182

One of the crucial choices when modelling species distributions using pseudo-absences approaches is the delineation of the background area to fit the model. We hypothesise that there is a minimum background area around the centre of the species distribution that characterizes well enough the range o…

Margaroni, S., Petersen, K. B., Gleadow, R., & Burd, M. (2019). The role of spore size in the global pattern of co-occurrence among Selaginella species. Journal of Biogeography. doi:10.1111/jbi.13532 https://doi.org/10.1111/jbi.13532

Aim: Separation of regeneration niches may promote coexistence among closely related plant species, but there is little evidence that regeneration traits affect species ranges at broad geographical scales. We address patterns of co‐occurrence within the genus Selaginella, an ancient lineage of free‐…

Karger, D. N., Kessler, M., Conrad, O., Weigelt, P., Kreft, H., König, C., & Zimmermann, N. E. (2019). Why tree lines are lower on islands-Climatic and biogeographic effects hold the answer. Global Ecology and Biogeography. doi:10.1111/geb.12897 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…

Biological invasion is increasing worldwide and the management of invasive species is becoming an important priority for vegetation managers. Success of invasive species management depends on a thorough understanding of the biology of the organism in question and the effectiveness of current managem…

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., Asase, A., Canhos, D., de Souza, S., & Wieczorek, J. (2018). Data Leakage and Loss in Biodiversity Informatics. Biodiversity Data Journal, 6. doi:10.3897/bdj.6.e26826 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…

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…

Invasive plant species (IPS) have a high potential for expanding within biodiversity hotspots and threatening global plant diversity. Hence, it is urgent to assess the expansion risk of IPS in regions of high plant diversity and their potentially negative effects throughout the world. We used the wo…

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…

Grossenbacher, D. L., Brandvain, Y., Auld, J. R., Burd, M., Cheptou, P.-O., Conner, J. K., … Goldberg, E. E. (2017). Self-compatibility is over-represented on islands. New Phytologist, 215(1), 469–478. doi:10.1111/nph.14534 https://doi.org/10.1111/nph.14534

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…

Aim Plant distributions and vegetation dynamics underpin key global phenomena, including biogeochemical cycling, ecosystem productivity and terrestrial biodiversity patterns. Aggregated and remotely collected ‘big data’ are required to forecast the effects of global change on plant communities. We s…

Tree ferns are a ubiquitous and often locally dominant element of wet southern temperate rainforests across Australasia, southern Africa and in regions adjacent to the tropics in South America. Published data on the ecology of tree ferns throughout these forest ecosystems is piecemeal, with the most…
