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…

Schubert, M., Groenvold, L., Sandve, S. R., Hvidsten, T. R., & Fjellheim, S. (2019). Evolution of cold acclimation and its role in niche transition in the temperate grass subfamily Pooideae. Plant Physiology, pp.01448.2018. doi:10.1104/pp.18.01448 https://doi.org/10.1104/pp.18.01448

The grass subfamily Pooideae dominates the grass floras in cold temperate regions, and has evolved complex physiological adaptations to cope with extreme environmental conditions like frost, winter and seasonality. One such adaptation is cold acclimation, wherein plants increase their frost toleranc…

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…

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…

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…

Milla, R., Bastida, J. M., Turcotte, M. M., Jones, G., Violle, C., Osborne, C. P., … Byun, C. (2018). Phylogenetic patterns and phenotypic profiles of the species of plants and mammals farmed for food. Nature Ecology & Evolution, 2(11), 1808–1817. doi:10.1038/s41559-018-0690-4 https://doi.org/10.1038/s41559-018-0690-4

The origins of agriculture were key events in human history, during which people came to depend for their food on small numbers of animal and plant species. However, the biological traits determining which species were domesticated for food provision, and which were not, are unclear. Here, we invest…

Inman, R., Franklin, J., Esque, T., & Nussear, K. (2018). Spatial sampling bias in the Neotoma paleoecological archives affects species paleo-distribution models. Quaternary Science Reviews, 198, 115–125. doi:10.1016/j.quascirev.2018.08.015 https://doi.org/10.1016/j.quascirev.2018.08.015

The ability to infer paleo-distributions with limited knowledge of absence makes species distribution modeling (SDM) a useful tool for exploring paleobiogeographic questions. Spatial sampling bias is a known issue when modeling extant species. Here we quantify the spatial sampling bias in a North Am…

Joffard, N., Massol, F., Grenié, M., Montgelard, C., & Schatz, B. (2018). Effect of pollination strategy, phylogeny and distribution on pollination niches of Euro‐Mediterranean orchids. Journal of Ecology, 107(1), 478–490. doi:10.1111/1365-2745.13013 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…

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…

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…
