Zhang, N., Z. Liao, S. Wu, M. P. Nobis, J. Wang, and N. Wu. 2021. Impact of climate change on wheat security through an alternate host of stripe rust. Food and Energy Security 11. https://doi.org/10.1002/fes3.356

In the 21st century, stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is still the most devastating disease of wheat globally. Despite the critical roles of the alternate host plants, the Berberis species, in the sexual reproduction and spread of Pst, the climate change impacts on t…

Vasconcelos, T., J. D. Boyko, and J. M. Beaulieu. 2021. Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. https://doi.org/10.1111/jbi.14292

Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…

Xue, T., S. R. Gadagkar, T. P. Albright, X. Yang, J. Li, C. Xia, J. Wu, and S. Yu. 2021. Prioritizing conservation of biodiversity in an alpine region: Distribution pattern and conservation status of seed plants in the Qinghai-Tibetan Plateau. Global Ecology and Conservation 32: e01885. https://doi.org/10.1016/j.gecco.2021.e01885

The Qinghai-Tibetan Plateau (QTP) harbors abundant and diverse plant life owing to its high habitat heterogeneity. However, the distribution pattern of biodiversity hotspots and their conservation status remain unclear. Based on 148,283 high-resolution occurrence coordinates of 13,450 seed plants, w…

TREVIÑO-ZEVALLOS, I., I. GARCÍA-CUNCHILLOS, and C. LADO. 2021. New records of Myxomycetes (Amoebozoa) from the tropical Andes. Phytotaxa 522: 231–239. https://doi.org/10.11646/phytotaxa.522.3.6

The Myxomycetes comprise a remarkably diverse group of organisms within Amoebozoa, with over 1000 species currently recognized. These organisms, at the end of their life cycles produce fruiting bodies which are the basis for their systematics. Despite being a biodiversity hotspot, the tropical Andes…

Zhang, M., R. Wei, Q. Xiang, A. Ebihara, and X. Zhang. 2021. Integrative taxonomy of the Selaginella helvetica group based on morphological, molecular and ecological data. TAXON 70: 1163–1187. https://doi.org/10.1002/tax.12565

The Eurasian and Mediterranean Selaginella helvetica group is one of the taxonomically challenging groups in the cosmopolitan lycophyte genus Selaginella. Species of the S. helvetica group are all small plants with lax strobili composed of more or less isomorphic sporophylls (isosporophylls) that ar…

Wang, C.-J., and J.-Z. Wan. 2021. Functional trait perspective on suitable habitat distribution of invasive plant species at a global scale. Perspectives in Ecology and Conservation 19: 475–486. https://doi.org/10.1016/j.pecon.2021.07.002

Plant invasion has been proved to threaten biodiversity conservation and ecosystem maintenance at a global scale. It is a challenge to project suitable habitat distributions of invasive plant species (IPS) for invasion risk assessment at large spatial scales. Interaction outcomes between native and …

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…

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…

Lake, T. A., R. D. Briscoe Runquist, and D. A. Moeller. 2020. Predicting range expansion of invasive species: Pitfalls and best practices for obtaining biologically realistic projections C. Bellard [ed.],. Diversity and Distributions 26: 1767–1779. 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…
