Dantas, & Pausas, J. G. (2022). The legacy of the extinct Neotropical megafauna on plants and biomes. Nature Communications, 13(1). https://doi.org/10.1038/s41467-021-27749-9 https://doi.org/10.1038/s41467-021-27749-9

Large mammal herbivores are important drivers of plant evolution and vegetation patterns, but the extent to which plant trait and ecosystem geography currently reflect the historical distribution of extinct megafauna is unknown. We address this question for South and Central America (Neotropical bio…

Freitas, C., Brum, F. T., Cássia-Silva, C., Maracahipes, L., Carlucci, M. B., Collevatti, R. G., & Bacon, C. D. (2021). Incongruent Spatial Distribution of Taxonomic, Phylogenetic, and Functional Diversity in Neotropical Cocosoid Palms. Frontiers in Forests and Global Change, 4. doi:10.3389/ffgc.2021.739468 https://doi.org/10.3389/ffgc.2021.739468

Biodiversity can be quantified by taxonomic, phylogenetic, and functional diversity. Current evidence points to a lack of congruence between the spatial distribution of these facets due to evolutionary and ecological constraints. A lack of congruence is especially evident between phylogenetic and ta…

Laeseke, P., Martínez, B., Mansilla, A., & Bischof, K. (2021). Invaders in waiting? Non-equilibrium in Southern Hemisphere seaweed distributions may lead to underestimation of Antarctic invasion potential. Frontiers of Biogeography, 13(4). doi:10.21425/f5fbg50879 https://doi.org/10.21425/f5fbg50879

Bioinvasions pose a major threat to global biodiversity. Correlative Ecological Niche Models (ENMs) can be a valuable tool to identify invaders and invasion sites. However, in cases when species are in non-equilibrium with their native environment (i.e. do not fill their niche), correlative approach…

Xue, T., Gadagkar, S. R., Albright, T. P., Yang, X., Li, J., Xia, C., … Yu, S. (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. doi:10.1016/j.gecco.2021.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…

O’Mahony, J., de la Torre Cerro, R., & Holloway, P. (2021). Modelling the Distribution of the Red Macroalgae Asparagopsis to Support Sustainable Aquaculture Development. AgriEngineering, 3(2), 251–265. doi:10.3390/agriengineering3020017 https://doi.org/10.3390/agriengineering3020017

Fermentative digestion by ruminant livestock is one of the main ways enteric methane enters the atmosphere, although recent studies have identified that including red macroalgae as a feed ingredient can drastically reduce methane produced by cattle. Here, we utilize ecological modelling to identify …

Hermsen, E. J. (2021). Review of the fossil record of Passiflora, with a description of new seeds from the Pliocene Gray Fossil Site, Tennessee, U.S.A. International Journal of Plant Sciences. doi:10.1086/714282 https://doi.org/10.1086/714282

Premise of the research. Passifloroideae (over 700 species), which include the large genus Passiflora (over 550 species), are distributed pantropically today. The fossil record of the group is, nevertheless, small and poorly understood. In this study, I provide a critical review of the fossil record…

De Jesús Hernández-Hernández, M., Cruz, J. A., & Castañeda-Posadas, C. (2020). Paleoclimatic and vegetation reconstruction of the miocene southern Mexico using fossil flowers. 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…

Goodwin, Z. A., Muñoz-Rodríguez, P., Harris, D. J., Wells, T., Wood, J. R. I., Filer, D., & Scotland, R. W. (2020). How long does it take to discover a species? Systematics and Biodiversity, 1–10. doi:10.1080/14772000.2020.1751339 https://doi.org/10.1080/14772000.2020.1751339

The description of a new species is a key step in cataloguing the World’s flora. However, this is only a preliminary stage in a long process of understanding what that species represents. We investigated how long the species discovery process takes by focusing on three key stages: 1, the collection …

Peyre, G., Lenoir, J., Karger, D. N., Gomez, M., Gonzalez, A., Broennimann, O., & Guisan, A. (2020). The fate of páramo plant assemblages in the sky islands of the northern Andes. Journal of Vegetation Science. doi:10.1111/jvs.12898 https://doi.org/10.1111/jvs.12898

Aims: Assessing climate change impacts on biodiversity is a main scientific challenge, especially in the tropics, therefore, we predicted the future of plant species and communities on the unique páramo sky islands. We implemented the Spatially Explicit Species Assemblage Modelling framework, by i) …

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.…
