Ritter, C. D., Faurby, S., Bennett, D. J., Naka, L. N., ter Steege, H., Zizka, A., … Antonelli, A. (2019). The pitfalls of biodiversity proxies: Differences in richness patterns of birds, trees and understudied diversity across Amazonia. Scientific Reports, 9(1). doi:10.1038/s41598-019-55490-3 https://doi.org/10.1038/s41598-019-55490-3

Most knowledge on biodiversity derives from the study of charismatic macro-organisms, such as birds and trees. However, the diversity of micro-organisms constitutes the majority of all life forms on Earth. Here, we ask if the patterns of richness inferred for macro-organisms are similar for micro-or…

Khoury, C. K., Carver, D., Barchenger, D. W., Barboza, G. E., Zonneveld, M., Jarret, R., … Greene, S. L. (2019). Modelled distributions and conservation status of the wild relatives of chile peppers ( Capsicum L.). Diversity and Distributions. doi:10.1111/ddi.13008 https://doi.org/10.1111/ddi.13008

Aim: To fill critical knowledge gaps with regard to the distributions and conservation status of the wild relatives of chile peppers (Capsicum L.). Location: The study covered the potential native ranges of currently recognized wild Capsicum taxa, throughout the Americas. Methods: We modelled the po…

Marconi, L., & Armengot, L. (2020). Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems. Agriculture, Ecosystems & Environment, 287, 106664. doi:10.1016/j.agee.2019.106664 https://doi.org/10.1016/j.agee.2019.106664

In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered.…

De Medeiros, B. A. S., Núñez-Avellaneda, L. A., Hernandez, A. M., & Farrell, B. D. (2019). Flower visitors of the licuri palm (Syagrus coronata): brood pollinators coexist with a diverse community of antagonists and mutualists. Biological Journal of the Linnean Society. doi:10.1093/biolinnean/blz008 https://doi.org/10.1093/biolinnean/blz008

Communities of plants and their insect brood pollinators have provided important insights into the evolution of mutualism. The discovery of new systems has the potential to extend our knowledge of the origins and consequences of these interactions. Many palms are known to be pollinated by beetles th…

Karger, D. N., Kessler, M., Conrad, O., Weigelt, P., Kreft, H., König, C., & Zimmermann, N. E. (2019). Why tree lines are lower on islands-Climatic and biogeographic effects hold the answer. Global Ecology and Biogeography. doi:10.1111/geb.12897 https://doi.org/10.1111/geb.12897

Aim: To determine the global position of tree line isotherms, compare it with observed local tree limits on islands and mainlands, and disentangle the potential drivers of a difference between tree line and local tree limit. Location: Global. Time period: 1979–2013. Major taxa studied: Trees. Method…

Goncalves, A. L., García, M. V., Heuertz, M., & González-Martínez, S. C. (2019). Demographic history and spatial genetic structure in a remnant population of the subtropical tree Anadenanthera colubrina var. cebil (Griseb.) Altschul (Fabaceae). Annals of Forest Science, 76(1). doi:10.1007/s13595-019-0797-z https://doi.org/10.1007/s13595-019-0797-z

Key message: A remnant population of Anadenanthera colubrina var. cebil in Northern Argentina showed a mixed mating system, high genetic diversity, and moderate spatial genetic structure, which was stronger in saplings than in adults. Demographic history analyses revealed an ancient population expan…

Crespo-Mendes, N., Laurent, A., & Hauschild, M. Z. (2018). Effect factors of terrestrial acidification in Brazil for use in Life Cycle Impact Assessment. The International Journal of Life Cycle Assessment. doi:10.1007/s11367-018-1560-7 https://doi.org/10.1007/s11367-018-1560-7

Purpose:In Life Cycle Impact Assessment, atmospheric fate factors, soil exposure factors, and effect factors are combined to characterize potential impacts of acidifying substances in terrestrial environments. Due to the low availability of global data sets, effect factors (EFs) have been reported a…

Crespo-Mendes, N., Laurent, A., Bruun, H. H., & Hauschild, M. Z. (2019). Relationships between plant species richness and soil pH at the level of biome and ecoregion in Brazil. Ecological Indicators, 98, 266–275. doi:10.1016/j.ecolind.2018.11.004 https://doi.org/10.1016/j.ecolind.2018.11.004

Soil pH has been used to indicate how changes in soil acidity can influence species loss. The correlation between soil pH and plant species richness has mainly been studied in North America and Europe, while there is a lack of studies exploring Tropical floras. Here, our aim was therefore to investi…

VÁZQUEZ-GARCÍA, J.-A., NEILL, D. A., SHALISKO, V., ARROYO, F., & MERINO-SANTI, R. E. (2018). Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution. Phytotaxa, 348(4), 254. doi:10.11646/phytotaxa.348.4.2 https://doi.org/10.11646/phytotaxa.348.4.2

Magnolia mercedesiarum, a new species from the eastern slopes of the Andes in northern Ecuador, is described and illustrated, and a key to Ecuadorian Magnolia (subsect. Talauma) is provided. This species differs from M. vargasiana in having broadly elliptic leaves that have an obtuse base vs. suborb…
