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…
Pisarenko, O. Yu., V. A. Bakalin, and E. A. Ignatova. 2020. Hookeria acutifolia (Hookeriaceae, Bryophyta), a new species for the moss flora of Russia. Botanica Pacifica. https://doi.org/10.17581/bp.2020.09104
Hookeria acutifolia Hook. & Grev. was found on Kunashir Island (South Kuril Islands, East Asia). This is the northernmost locality of the species in Asia and the first record for Russia. A description and illustrations of the species based on the Russian specimen are provided. Details on its ecology…
Schafstall, N., N. Kuosmanen, C. J. Fettig, M. Knižek, and J. L. Clear. 2020. Late Glacial and Holocene records of tree-killing conifer bark beetles in Europe and North America: Implications for forest disturbance dynamics. The Holocene 30: 847–857. https://doi.org/10.1177/0959683620902214
Outbreaks of conifer bark beetles in Europe and North America have increased in scale and severity in recent decades. In this study, we identify existing fossil records containing bark beetle remains from the end of the Last Glacial Maximum (~14,000 cal. yr BP) to present day using the online databa…
Han, T., Q. Zheng, R. E. Onstein, B. M. Rojas‐Andrés, F. Hauenschild, A. N. Muellner‐Riehl, and Y. Xing. 2019. Polyploidy promotes species diversification of Allium through ecological shifts. New Phytologist 225: 571–583. https://doi.org/10.1111/nph.16098
Despite the role of polyploidy in multiple evolutionary processes, its impact on plant diversification remains controversial. An increased polyploid frequency may facilitate speciation through shifts in ecology, morphology, or both. Here we used Allium to evaluate (1) the relationship between intras…
Fletcher, T. L., L. Warden, J. S. Sinninghe Damsté, K. J. Brown, N. Rybczynski, J. C. Gosse, and A. P. Ballantyne. 2019. Evidence for fire in the Pliocene Arctic in response to amplified temperature. Climate of the Past 15: 1063–1081. 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…
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…
Rotllan-Puig, X., and A. Traveset. 2019. Determining the Minimal Background Area for Species Distribution Models: MinBar PACKAGE. 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…
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…
Joffard, N., F. Massol, M. Grenié, C. Montgelard, and B. Schatz. 2018. Effect of pollination strategy, phylogeny and distribution on pollination niches of Euro‐Mediterranean orchids I. Bartomeus [ed.],. Journal of Ecology 107: 478–490. https://doi.org/10.1111/1365-2745.13013
1.Pollination niches are important components of ecological niches and have played a major role in the diversification of Angiosperms. In this study, we focused on Euro‐Mediterranean orchids, which use diverse pollination strategies and interact with various functional groups of insects. In these or…
