Singhal, S., A. B. Roddy, C. DiVittorio, A. Sanchez‐Amaya, C. L. Henriquez, C. R. Brodersen, S. Fehlberg, and F. Zapata. 2021. Diversification, disparification and hybridization in the desert shrubs Encelia. New Phytologist 230: 1228–1241. https://doi.org/10.1111/nph.17212
There are multiple hypotheses for the spectacular plant diversity found in deserts. We explore how different factors, including the roles of ecological opportunity and selection, promote diversification and disparification in Encelia, a lineage of woody plants in the deserts of the Americas. Using a…
Allstädt, F. J., A. Koutsodendris, E. Appel, W. Rösler, T. Reichgelt, S. Kaboth-Bahr, A. A. Prokopenko, and J. Pross. 2021. Late Pliocene to early Pleistocene climate dynamics in western North America based on a new pollen record from paleo-Lake Idaho. Palaeobiodiversity and Palaeoenvironments 101: 177–195. https://doi.org/10.1007/s12549-020-00460-1
Marked by the expansion of ice sheets in the high latitudes, the intensification of Northern Hemisphere glaciation across the Plio/Pleistocene transition at ~ 2.7 Ma represents a critical interval of late Neogene climate evolution. To date, the characteristics of climate change in North America duri…
Brendel, M. R., F. M. Schurr, and C. S. Sheppard. 2020. Inter‐ and intraspecific selection in alien plants: How population growth, functional traits and climate responses change with residence time A. Ordonez [ed.],. Global Ecology and Biogeography 30: 429–442. https://doi.org/10.1111/geb.13228
Aim: When alien species are introduced to new ranges, climate or trait mismatches may initially constrain their population growth. However, inter‐ and intraspecific selection in the new environment should cause population growth rates to increase with residence time. Using a species‐for‐time approac…
Büchi, L., S. Cordeau, R. Hull, and J. Rodenburg. 2020. Vulpia myuros , an increasing threat for agriculture L. J. Rew [ed.],. Weed Research 61: 13–24. https://doi.org/10.1111/wre.12456
Vulpia myuros is an annual grass species of Mediterranean origin, which has achieved a global distribution. It is a fast‐growing species, with high colonisation and competitive abilities. This species is considered an invasive weed in most countries where it has been introduced, with highly negative…
Bazzicalupo, A. L., J. Whitton, and M. L. Berbee. 2019. Over the hills, but how far away? Estimates of mushroom geographic range extents. Journal of Biogeography. https://doi.org/10.1111/jbi.13617
Aim: Geographic distributions of mushroom species remain poorly understood despite their importance for advancing our understanding of the habitat requirements, species interactions and ecosystem functions of this key group of organisms. Here, we estimate geographic range extents (maximum within‐spe…
Mason, C. M., M. C. LaScaleia, D. R. De La Pascua, J. G. Monroe, and E. W. Goolsby. 2020. Learning from Dynamic Traits: Seasonal Shifts Yield Insights into Ecophysiological Trade-Offs across Scales from Macroevolutionary to Intraindividual. International Journal of Plant Sciences 181: 88–102. https://doi.org/10.1086/706238
Premise of the Research. Phylogenetic comparative methods provide a powerful approach for exploring the macroevolution of plant functional traits. Such approaches can uncover trait-trait correlations through evolutionary time, as well as provide evidence of the role of traits in adaptation across en…
De La Pascua, D. R., C. Smith‐Winterscheidt, J. A. Dowell, E. W. Goolsby, and C. M. Mason. 2020. Evolutionary trade‐offs in the chemical defense of floral and fruit tissues across genus Cornus. American Journal of Botany 107: 1260–1273. https://doi.org/10.1002/ajb2.1540
Premise: Defense investment in plant reproductive structures is relatively understudied compared to the defense of vegetative organs. Here the evolution of chemical defenses in reproductive structures is examined in light of the optimal defense, apparency, and resource availability hypotheses within…
Zizka, A., F. Antunes Carvalho, A. Calvente, M. Rocio Baez-Lizarazo, A. Cabral, J. F. R. Coelho, M. Colli-Silva, et al. 2020. No one-size-fits-all solution to clean GBIF. PeerJ 8: e9916. https://doi.org/10.7717/peerj.9916
Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, th…

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…
O’Connell, E., and J. Savage. 2020. Extended leaf phenology has limited benefits for invasive species growing at northern latitudes. Biological Invasions 22: 2957–2974. 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…
