Hoorn, C., T. Kukla, G. Bogotá-Angel, E. van Soelen, C. González-Arango, F. P. Wesselingh, H. Vonhof, et al. 2022. Cyclic sediment deposition by orbital forcing in the Miocene wetland of western Amazonia? New insights from a multidisciplinary approach. Global and Planetary Change 210: 103717. https://doi.org/10.1016/j.gloplacha.2021.103717
In the Miocene, a large wetland system extended from the Andean foothills into western Amazonia. This system has no modern analogue and the driving mechanisms are not yet fully understood. Dynamic topography and Andean uplift are thought to have controlled deposition, with allocyclic base level chan…
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…
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…
Deanna, R., P. Wilf, and M. A. Gandolfo. 2020. New physaloid fruit‐fossil species from early Eocene South America. American Journal of Botany 107: 1749–1762. https://doi.org/10.1002/ajb2.1565
Premise: Solanaceae is a scientifically and economically important angiosperm family with a minimal fossil record and an intriguing early evolutionary history. Here, we report a newly discovered fossil lantern fruit with a suite of features characteristic of Physalideae within Solanaceae. The fossil…
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…
Khoury, C. K., D. Carver, D. W. Barchenger, G. E. Barboza, M. Zonneveld, R. Jarret, L. Bohs, et al. 2019. Modelled distributions and conservation status of the wild relatives of chile peppers ( Capsicum L.) J. Lambrinos [ed.],. Diversity and Distributions 26: 209–225. 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…
Crespo-Mendes, N., A. Laurent, and M. Z. Hauschild. 2018. Effect factors of terrestrial acidification in Brazil for use in Life Cycle Impact Assessment. The International Journal of Life Cycle Assessment 24: 1105–1117. 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., A. Laurent, H. H. Bruun, and M. Z. Hauschild. 2019. Relationships between plant species richness and soil pH at the level of biome and ecoregion in Brazil. Ecological Indicators 98: 266–275. 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., D. A. NEILL, V. SHALISKO, F. ARROYO, and R. E. MERINO-SANTI. 2018. Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution. Phytotaxa 348: 254. 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…
