A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates. This assumption is rarely met when SDM practition…

Carnivorous plants (CPs)—those possessing specific strategies to attract, capture and kill animal prey and obtain nutrition through the absorption of their biomass—are harbingers of anthropogenic degradation and destruction of ecosystems. CPs exhibit highly specialised and often very sensitive ecolo…

Journal of South American Earth Sciences, 104, 102827. doi:10.1016/j.jsames.2020.102827 https://doi.org/10.1016/j.jsames.2020.102827

Concern about the course of the current environmental problems has raised interest in investigating the different scenarios that have taken place in our planet throughout time. To that end, different methodologies have been employed in order to determine the different variables that compose the envi…

Goodwin, Z. A., Muñoz-Rodríguez, P., Harris, D. J., Wells, T., Wood, J. R. I., Filer, D., & Scotland, R. W. (2020). How long does it take to discover a species? Systematics and Biodiversity, 1–10. doi:10.1080/14772000.2020.1751339 https://doi.org/10.1080/14772000.2020.1751339

The description of a new species is a key step in cataloguing the World’s flora. However, this is only a preliminary stage in a long process of understanding what that species represents. We investigated how long the species discovery process takes by focusing on three key stages: 1, the collection …

Léveillé-Bourret, É., Chen, B.-H., Garon-Labrecque, M.-È., Ford, B. A., & Starr, J. R. (2019). RAD sequencing resolves the phylogeny, taxonomy and biogeography of Trichophoreae despite a rapid recent radiation (Cyperaceae). Molecular Phylogenetics and Evolution, 106727. doi:10.1016/j.ympev.2019.106727 https://doi.org/10.1016/j.ympev.2019.106727

Trichophoreae is a nearly cosmopolitan Cyperaceae tribe that contains ∼17 species displaying striking variation in size, inflorescence complexity, and perianth morphology. Although morphologically distinct, the status of its three genera (Cypringlea, Oreobolopsis and Trichophorum) are controversial …

Berg, C. S., Brown, J. L., & Weber, J. J. (2019). An examination of climate‐driven flowering‐time shifts at large spatial scales over 153 years in a common weedy annual. American Journal of Botany. doi:10.1002/ajb2.1381 https://doi.org/10.1002/ajb2.1381

Premise: Understanding species’ responses to climate change is a critical challenge facing biologists today. Though many species are widespread, few studies of climate‐driven shifts in flowering time have examined large continuous spatial scales for individual species. And even fewer studies have ex…

Lebeda, A., Křístková, E., Kitner, M., Majeský, Ľ., Doležalová, I., Khoury, C. K., … Sosa, C. C. (2019). Research Gaps and Challenges in the Conservation and Use of North American Wild Lettuce Germplasm. Crop Science, 0(0), 0. doi:10.2135/cropsci2019.05.0350 https://doi.org/10.2135/cropsci2019.05.0350

The North American crop wild relatives (CWR) of lettuce (Lactuca L.) represent an underexplored pool of genetic diversity of potential value to breeding programs. The 10 species belong to three different groups: a native clade including at least six allotetraploid species [L. biennis (Moench) Fernal…

Plant breeding systems can vary widely among populations, yet few studies have investigated abiotic factors contributing to variation across a broad geographic range. Here we investigate variation in reproductive traits of Triodanis perfoliata (Campanulaceae), a species that exhibits dimorphic cleis…

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…
