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…

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…

Bellot, S., Bayton, R. P., Couvreur, T. L. P., Dodsworth, S., Eiserhardt, W. L., Guignard, M. S., … Baker, W. J. (2020). On the origin of giant seeds: the macroevolution of the double coconut ( Lodoicea maldivica ) and its relatives (Borasseae, Arecaceae). New Phytologist. doi:10.1111/nph.16750 https://doi.org/10.1111/nph.16750

Seed size shapes plant evolution and ecosystems, and may be driven by plant size and architecture, dispersers, habitat and insularity. How these factors influence the evolution of giant seeds is unclear, as are the rate of evolution and the biogeographical consequences of giant seeds. We generated D…

Carrasco, J., Price, V., Tulloch, V., & Mills, M. (2020). Selecting priority areas for the conservation of endemic trees species and their ecosystems in Madagascar considering both conservation value and vulnerability to human pressure. Biodiversity and Conservation. doi:10.1007/s10531-020-01947-1 https://doi.org/10.1007/s10531-020-01947-1

Madagascar is one of the most biodiverse countries in Africa, due to its level of endemism and species diversity. However, the pressure of human activities threatens the last patches of natural vegetation in the country and conservation decisions are undertaken with limited data availability. In thi…

Hawthorne, W. D., & Marshall, C. A. M. (2019). Rapid Botanic Survey, Bioquality and improving botanical inventory in the tropics by integrating across spatial scales. Gardens’ Bulletin Singapore, 71(suppl.2), 315–333. doi:10.26492/gbs71(suppl.2).2019-21 https://doi.org/10.26492/gbs71(suppl.2).2019-21

We review the Rapid Botanic Survey method (RBS), in the context of botanical recording to date. The concept of bioquality, a biodiversity value respecting global rarity, is summarised. Bioquality assessment involves the Star system for categorising species by global rarity; and a Genetic Heat Index …

Margaroni, S., Petersen, K. B., Gleadow, R., & Burd, M. (2019). The role of spore size in the global pattern of co-occurrence among Selaginella species. Journal of Biogeography. doi:10.1111/jbi.13532 https://doi.org/10.1111/jbi.13532

Aim: Separation of regeneration niches may promote coexistence among closely related plant species, but there is little evidence that regeneration traits affect species ranges at broad geographical scales. We address patterns of co‐occurrence within the genus Selaginella, an ancient lineage of free‐…

Park, D. S., & Razafindratsima, O. H. (2018). Anthropogenic threats can have cascading homogenizing effects on the phylogenetic and functional diversity of tropical ecosystems. Ecography, 42(1), 148–161. doi:10.1111/ecog.03825 https://doi.org/10.1111/ecog.03825

Determining the mechanisms that underlie species distributions and assemblages is necessary to effectively preserve biodiversity. This cannot be accomplished by examining a single taxonomic group, as communities comprise a plethora of interactions across species and trophic levels. Here, we examine …

Piel, W. H. (2018). The global latitudinal diversity gradient pattern in spiders. Journal of Biogeography, 45(8), 1896–1904. doi:10.1111/jbi.13387 https://doi.org/10.1111/jbi.13387

Aim: The aim of this study was to test the hypothesis that the global latitudinal diversity gradient pattern in spiders is pear‐shaped, with maximum species diversity shifted south of the Equator, rather than egg‐shaped, centred on the equator, this study infers the gradient using two large datasets…

Petersen, K. B., & Burd, M. (2018). The adaptive value of heterospory: Evidence from Selaginella . Evolution, 72(5), 1080–1091. doi:10.1111/evo.13484 https://doi.org/10.1111/evo.13484

Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. We used the geographic distributions of 114 species of the heterosporous lycophyte Selaginella to explore the functional ecology of microspore and megaspore size, traits that would be corre…

Sundue, M. A. (2017). Ceradenia spectabilis (Polypodiaceae), a New Species from Cerro del Torrá, Colombia. American Fern Journal, 107(4), 193–199. doi:10.1640/0002-8444-107.4.193 https://doi.org/10.1640/0002-8444-107.4.193

Ceradenia spectabilis, a new species, is described from Cerro del Torrá, an isolated peak in western Colombia well known for harboring rare and narrowly distributed species of plants. The new species is readily distinguished from its congeners by its broadly alate petiole and rachis, creeping rhizom…
