Armitage, D. W., & Jones, S. E. (2020). Coexistence barriers confine the poleward range of a globally distributed plant. Ecology Letters, 23(12), 1838–1848. doi:10.1111/ele.13612 https://doi.org/10.1111/ele.13612

In the study of factors shaping species' poleward range boundaries, climatic constraints are often assigned greater importance than biotic interactions such as competition. However, theory suggests competition can truncate a species' fundamental niche in harsh environments. We test this by challengi…

Lake, T. A., Briscoe Runquist, R. D., & Moeller, D. A. (2020). Predicting range expansion of invasive species: Pitfalls and best practices for obtaining biologically realistic projections. Diversity and Distributions, 26(12), 1767–1779. doi:10.1111/ddi.13161 https://doi.org/10.1111/ddi.13161

Aim: Species distribution models (SDMs) are widely used to forecast potential range expansion of invasive species. However, invasive species occurrence datasets often have spatial biases that may violate key SDM assumptions. In this study, we examined alternative methods of spatial bias correction a…

Cross, A. T., Krueger, T. A., Gonella, P. M., Robinson, A. S., & Fleischmann, A. S. (2020). Conservation of carnivorous plants in the age of extinction. Global Ecology and Conservation, e01272. doi:10.1016/j.gecco.2020.e01272 https://doi.org/10.1016/j.gecco.2020.e01272

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…

Brightly, W. H., Hartley, S. E., Osborne, C. P., Simpson, K. J., & Strömberg, C. A. E. (2020). High silicon concentrations in grasses are linked to environmental conditions and not associated with C 4 photosynthesis. Global Change Biology. doi:10.1111/gcb.15343 https://doi.org/10.1111/gcb.15343

The uptake and deposition of silicon (Si) as silica phytoliths is common among land plants and is associated with a variety of functions. Among these, herbivore defense has received significant attention, particularly with regards to grasses and grasslands. Grasses are well known for their high sili…

Chevalier, M., Chase, B. M., Quick, L. J., Dupont, L. M., & Johnson, T. C. (2020). Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology. doi:10.1130/g47841.1 https://doi.org/10.1130/G47841.1

Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…

Lindelof, K., Lindo, J. A., Zhou, W., Ji, X., & Xiang, Q. (Jenny). (2020). Phylogenomics, biogeography, and evolution of the blue‐ or white‐fruited dogwoods ( Cornus ) ‐ insights into morphological and ecological niche divergence following intercontinental geographic isolation. Journal of Systematics and Evolution. doi:10.1111/jse.12676 https://doi.org/10.1111/jse.12676

The eastern Asian (EA)–eastern North American (ENA) floristic disjunction represents a major pattern of phytogeography of the Northern Hemisphere. Despite 20 years of studies dedicated to identification of taxa that display this disjunct pattern, its origin and evolution remain an open question, esp…

De Jesús Hernández-Hernández, M., Cruz, J. A., & Castañeda-Posadas, C. (2020). Paleoclimatic and vegetation reconstruction of the miocene southern Mexico using fossil flowers. 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…

Li, K., Wang, J., Qiao, L., Zheng, R., Ma, Y., Chen, Y., … Liu, H. (2020). Diversity of Reproductive Phenology Among Subtropical Grasses Is Constrained by Evolution and Climatic Niche. Frontiers in Ecology and Evolution, 8. doi:10.3389/fevo.2020.00181 https://doi.org/10.3389/fevo.2020.00181

Reproductive phenology is sensitive to climatic changes and is associated with species functional types, distribution ranges, and their corresponding climatic niches. Phylogenetic niche conservatism in reproductive phenology also constrains its diversity and the distribution of species. Therefore, w…

Wierzcholska, S., Dyderski, M. K., & Jagodziński, A. M. (2020). Potential distribution of an epiphytic bryophyte depends on climate and forest continuity. Global and Planetary Change, 193, 103270. doi:10.1016/j.gloplacha.2020.103270 https://doi.org/10.1016/j.gloplacha.2020.103270

Woodland-specialist epiphytic bryophytes are both a threatened ecological guild of forest species as well as a precise bioindicator of conservation value of forest ecosystems. However, due to lack of data on distribution, there is no information about their potential reaction to predicted climate ch…

O’Connell, E., & Savage, J. (2020). Extended leaf phenology has limited benefits for invasive species growing at northern latitudes. Biological Invasions. doi:10.1007/s10530-020-02301-w https://doi.org/10.1007/s10530-020-02301-w

Many understory woody invasive plants in North America leaf out earlier or retain leaves later than their native associates. This extended leaf phenology is thought to grant invasive species an advantage over native species because spring and fall are crucial times for light access and carbon acquis…
