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…

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…

Speed, J. D. M., Austrheim, G., Bendiksby, M., Kolstad, A. L., & Vuorinen, K. E. M. (2020). Increasing Cervidae populations have variable impacts on habitat suitability for threatened forest plant and lichen species. Forest Ecology and Management, 473, 118286. doi:10.1016/j.foreco.2020.118286 https://doi.org/10.1016/j.foreco.2020.118286

Large herbivores play a key role in temperate and boreal forest ecosystems. Cervidae (deer) population densities and community structure have undergone drastic changes in many parts of the world over the past decades, often with deer populations increasing. Many studies show impacts of Cervidae on m…

Adhikari, S., Burke, I. C., & Eigenbrode, S. D. (2020). Mayweed chamomile ( Anthemis cotula L.) biology and management—A review of an emerging global invader. Weed Research. doi:10.1111/wre.12426 https://doi.org/10.1111/wre.12426

The globally invasive weed, mayweed chamomile (Anthemis cotula L.) is an annual, bushy, ill‐scented herb, originating in Eurasia. It is aggressively weedy in croplands, field‐side ditches, wet areas and along roadsides, especially in slightly acidic, nitrogen‐rich, clay‐loam soils. In addition to in…

Jahanshiri, E., Mohd Nizar, N. M., Tengku Mohd Suhairi, T. A. S., Gregory, P. J., Mohamed, A. S., Wimalasiri, E. M., & Azam-Ali, S. N. (2020). A Land Evaluation Framework for Agricultural Diversification. Sustainability, 12(8), 3110. doi:10.3390/su12083110 https://doi.org/10.3390/su12083110

Shortlisting ecologically adaptable plant species can be a starting point for agricultural diversification projects. We propose a rapid assessment framework based on an ecological model that can accelerate the evaluation of options for sustainable crop diversification. To test the new model, expert-…

Lindberg, C. L., Hanslin, H. M., Schubert, M., Marcussen, T., Trevaskis, B., Preston, J. C., & Fjellheim, S. (2020). Increased above ground resource allocation is a likely precursor for independent evolutionary origins of annuality in the Pooideae grass subfamily. New Phytologist. doi:10.1111/nph.16666 https://doi.org/10.1111/nph.16666

Semelparous annual plants flower a single time during their one‐year life cycle, investing much of their energy into rapid reproduction. In contrast, iteroparous perennial plants flower multiple times over several years, and partition their resources between reproduction and persistence. To which ex…

Van Treuren, R., Hoekstra, R., Wehrens, R., & van Hintum, T. (2020). Effects of climate change on the distribution of crop wild relatives in the Netherlands in relation to conservation status and ecotope variation. Global Ecology and Conservation, 23, e01054. doi:10.1016/j.gecco.2020.e01054 https://doi.org/10.1016/j.gecco.2020.e01054

Crop wild relatives (CWR) are wild plant taxa that are genetically related to a cultivated species and are considered rich sources of useful traits for crop improvement. CWR are generally underrepresented in genebanks, while their survival in nature is not guaranteed. Inventories and risk analyses a…

De Paula, A. S., & Barreto, C. (2020). Potential Distribution of Nysius simulans (Hemiptera: Lygaeidae) in Soybean Crops in South America Under Current and Future Climate. Journal of Economic Entomology. doi:10.1093/jee/toaa089 https://doi.org/10.1093/jee/toaa089

Nysius simulans (Stål) is a suctorial, fluid feeding herbivore that can transmit toxins and spread pathogens via saliva and is an economically important pest for soybean in South America. Currently, N. simulans in soybean is predominantly found in Argentina, but future changes in the distribution fr…

Global changes pose both risks and opportunities to agriculture and forestry, and biological forecasts can inform future management strategies. Here, we investigate potential land-use opportunities arising from climate change for these sectors in Europe, and risks associated with the introduction an…
