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…

Myricaria germanica (German tamarisk or false tamarisk), Tamaricaceae, is a pioneer shrub native to the Eurasian temperate regions where it colonises gravel bars in braided rivers. Over the past 150 years, human alterations of rivers have caused its dramatic decline in Europe. This paper reviews the…

The tropical forests of Central America serve a pivotal role as biodiversity hotspots and provide ecosystem services securing human livelihood. However, climate change is expected to affect the species composition of forest ecosystems, lead to forest type transitions and trigger irrecoverable losses…

Ulex europaeus (Gorse) is one of the most invasive shrubs in the world, being now found in more than 50 countries where it economically and environmentally degrades the land. This highly versatile shrub can live more than 30 years and produce over 18,000 fertile seeds annually that can remain viable…
Kriticos, D. J., K. B. Ireland, L. Morin, N. Kumaran, M. A. Rafter, N. Ota, and S. Raghu. 2021. Integrating ecoclimatic niche modelling methods into classical biological control programmes. Biological Control 160: 104667. https://doi.org/10.1016/j.biocontrol.2021.104667
Much of the success of a classical biological control programme hinges on identifying effective candidate agents, and once approved for release deploying them in the range invaded by the target organism at site-specific times of the year when they have the best chance of establishing. While suitable…
Ruiz, D. P., R. R. Pujana, and M. Brea. 2021. Early Miocene paleoclimate in southern Patagonia inferred from fossil woods. Review of Palaeobotany and Palynology 290: 104429. https://doi.org/10.1016/j.revpalbo.2021.104429
Patagonia has a rich record of fossil woods that are a unique data store of paleoclimatic information. We studied the wood flora recovered from the Río Leona Formation (early Miocene) of southern Patagonia near El Calafate and Río Turbio localities, Santa Cruz Province, Argentina. The fossil wood as…

Grasslands play an important ecological role and are the dominant landscape in the whole extent of the Andes and high elevation regions of South America. Climate change models indicate a strong impact on mountain systems. The climatic conditions of mountain systems are greatly influenced by topograp…
Saldaña‐López, A., M. Vilà, F. Lloret, J. Manuel Herrera, and P. González‐Moreno. 2021. Assembly of species’ climatic niches of coastal communities does not shift after invasion Z. Botta‐Dukát [ed.],. Journal of Vegetation Science 32. https://doi.org/10.1111/jvs.12989
Question: Do invasions by invasive plant species with contrasting trait profiles (Arctotheca calendula, Carpobrotus spp., Conyza bonariensis, and Opuntia dillenii) change the climatic niche of coastal plant communities? Location: Atlantic coastal habitats in Huelva (Spain). Methods: We identifi…
Pérez‐Navarro, M. Á., J. M. Serra‐Diaz, J. Svenning, M. Á. Esteve‐Selma, J. Hernández‐Bastida, and F. Lloret. 2021. Extreme drought reduces climatic disequilibrium in dryland plant communities. Oikos 130: 680–690. https://doi.org/10.1111/oik.07882
High rates of climate change are currently exceeding many plant species' capacity to keep up with climate, leading to mismatches between climatic conditions and climatic preferences of the species present in a community. This disequilibrium between climate and community composition could diminish, h…
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…
