Mejía-Falla, P. A., Castro, E., Bolaños, N., Caldas, J. P., Ballesteros, C., Bent-Hooker, H., … Navia, A. F. (2020). Richness and distribution patterns of elasmobranchs in the San Andres, Providencia and Santa Catalina Archipelago: is this area a hotspot of these species in the greater Caribbean? Environmental Biology of Fishes. doi:10.1007/s10641-020-01029-9 https://doi.org/10.1007/s10641-020-01029-9

Hotspots identification can be used to establish protected or priority areas for conservation at different geographic scales. We aimed to determine if San Andres, Providencia and Santa Catalina Archipelago could be considered as a hotspot of elasmobranch diversity within the Greater Caribbean. For t…

Fazlioglu, F., Wan, J. S. H., & Chen, L. (2020). Latitudinal shifts in mangrove species worldwide: evidence from historical occurrence records. Hydrobiologia. doi:10.1007/s10750-020-04403-x https://doi.org/10.1007/s10750-020-04403-x

Consequences of global climate change on mangrove habitats are ambiguous owing to multifaceted factors. In this study, we examined historical occurrences of ten common mangrove species and quantified the rate of latitudinal shift as a possible response to climate change. The Global Biodiversity Info…

Mill. e as Mudanças Climáticas: Uma Análise a Luz da Modelagem de Distribuição de Espécies no Bioma Caatinga. Revista Brasileira de Meteorologia. doi:10.1590/0102-7786353001 https://doi.org/10.1590/0102-7786353001

Resumo As previsões de mudanças climáticas no bioma Caatinga para esse século são de aumento na temperatura do ar e redução das chuvas. A combinação desse fenômeno físico com invasões biológicas pode potencializar perdas de biodiversidade local. O objetivo do estudo foi modelar a distribuição potenc…

Kolanowska, M., Rewicz, A., & Baranow, P. (2020). Ecological niche modeling of the pantropical orchid Polystachya concreta (Orchidaceae) and its response to climate change. Scientific Reports, 10(1). doi:10.1038/s41598-020-71732-1 https://doi.org/10.1038/s41598-020-71732-1

Climate is the dominant control factor on the spatial distribution of organisms on a global scale and global warming is predicted to become a major cause of species extinctions. In our study ecological niche modeling (ENM) was used to estimate the effect of projected future climate changes on the pa…

Brightly, W. H., Hartley, S. E., Osborne, C. P., Simpson, K. J., & Strömberg, C. A. E. (2020). High silicon concentrations in grasses are linked to environmental conditions and not associated with C 4 photosynthesis. Global Change Biology. doi:10.1111/gcb.15343 https://doi.org/10.1111/gcb.15343

The uptake and deposition of silicon (Si) as silica phytoliths is common among land plants and is associated with a variety of functions. Among these, herbivore defense has received significant attention, particularly with regards to grasses and grasslands. Grasses are well known for their high sili…

Chevalier, M., Chase, B. M., Quick, L. J., Dupont, L. M., & Johnson, T. C. (2020). Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology. doi:10.1130/g47841.1 https://doi.org/10.1130/G47841.1

Across the glacial-interglacial cycles of the late Pleistocene (~700 k.y.), temperature variability at low latitudes is often considered to have been negligible compared to changes in precipitation. However, a paucity of quantified temperature records makes this difficult to reliably assess. In this…

Tan, K., Lu, T., & Ren, M.-X. (2020). Biogeography and evolution of Asian Gesneriaceae based on updated taxonomy. PhytoKeys, 157, 7–26. doi:10.3897/phytokeys.157.34032 https://doi.org/10.3897/phytokeys.157.34032

Based on an updated taxonomy of Gesneriaceae, the biogeography and evolution of the Asian Gesneriaceae are outlined and discussed. Most of the Asian Gesneriaceae belongs to Didymocarpoideae, except Titanotrichum was recently moved into Gesnerioideae. Most basal taxa of the Asian Gesneriaceae are fou…

Zhernova, D. A., Nilova, M. V., & Oskolski, A. A. (2020). Comparative wood anatomy of Astropanax and Neocussonia, an Afro-Malagasy lineage of Araliaceae. Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boaa067 https://doi.org/10.1093/botlinnean/boaa067

Astropanax and Neocussonia are two recently resurrected genera of Araliaceae that had long been considered as an Afro-Malagasy lineage of Schefflera. The wood structure of 11 Neocussonia spp. and eight Astropanax spp. has been studied. Neocussonia shows a higher average length of vessel elements (13…

Phylogenomics, biogeography, and evolution of the blue‐ or white‐fruited dogwoods ( Cornus ) ‐ insights into morphological and ecological niche divergence following intercontinental geographic isolation. Journal of Systematics and Evolution. doi:10.1111/jse.12676 https://doi.org/10.1111/jse.12676

The eastern Asian (EA)–eastern North American (ENA) floristic disjunction represents a major pattern of phytogeography of the Northern Hemisphere. Despite 20 years of studies dedicated to identification of taxa that display this disjunct pattern, its origin and evolution remain an open question, esp…

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…
