A new species of climbing Chamaedorea (Arecaceae) from Chiapas, Mexico. Phytotaxa, 522(2), 94–108. doi:10.11646/phytotaxa.522.2.2 https://doi.org/10.11646/phytotaxa.522.2.2

Chamaedorea tacanensis (Arecaceae), a new species from the Tacaná Volcano Biosphere Reserve, Chiapas, Mexico, is described based on morphological and phylogenetic data. It is morphologically similar to C. elatior, the only other climbing species in the genus. However, C. tacanensis is distinguished …

Liu, J., Wang, L., Sun, C., Xi, B., Li, D., Chen, Z., … Jia, L. (2021). Global distribution of soapberries (Sapindus L.) habitats under current and future climate scenarios. Scientific Reports, 11(1). doi:10.1038/s41598-021-98389-8 https://doi.org/10.1038/s41598-021-98389-8

Sapindus (Sapindus L.) is a widely distributed economically important tree genus that provides biodiesel, biomedical and biochemical products. However, with climate change, deforestation, and economic development, the diversity of Sapindus germplasms may face the risk of destruction. Therefore, util…

Franco, M. J., Brea, M., & Cerdeño, E. (2021). First Bignoniaceae liana from the Miocene of South America and its evolutionary significance. American Journal of Botany. doi:10.1002/ajb2.1736 https://doi.org/10.1002/ajb2.1736

Premise: Two Bignoniaceae stems with the distinctive anatomy of a liana are described from the Miocene of South America. They are the first fossil evidence of climbing habit in Bignoniaceae. Methods: The fossil lianas are siliceous permineralizations. Transverse, tangential, and radial thin section…

Abstract Tithonia diversifolia (Mexican sunflower) is an invasive plant, native to the New World, and an exemplary conflict species. It has been planted widely for its ornamental and soil fertility enhancement qualities and has become a notorious environmental weed in introduced habitats. Here we us…

Whitman, M., Beaman, R. S., Repin, R., Kitayama, K., Aiba, S., & Russo, S. E. (2021). Edaphic specialization and vegetation zones define elevational range‐sizes for Mt Kinabalu regional flora. Ecography. doi:10.1111/ecog.05873 https://doi.org/10.1111/ecog.05873

Identifying physical and ecological boundaries that limit where species can occur is important for predicting how those species will respond to global change. The island of Borneo encompasses a wide range of habitats that support some of the highest richness on Earth, making it an ideal location for…

Ma, C.-S., Zhang, W., Peng, Y., Zhao, F., Chang, X.-Q., Xing, K., … Rudolf, V. H. W. (2021). Climate warming promotes pesticide resistance through expanding overwintering range of a global pest. Nature Communications, 12(1). doi:10.1038/s41467-021-25505-7 https://doi.org/10.1038/s41467-021-25505-7

Climate change has the potential to change the distribution of pests globally and their resistance to pesticides, thereby threatening global food security in the 21st century. However, predicting where these changes occur and how they will influence current pest control efforts is a challenge. Using…

Chukwuma, D. M., & Ayodele, A. E. (2021). Wood micro-morphological characteristics of the Tribe Dalbergieae in Nigeria. Webbia, 76(2), 295–306. doi:10.36253/jopt-11407 https://doi.org/10.36253/jopt-11407

The present study examined the wood micro-characters of 18 species of the tribe Dalbergieae across 4 genera in Nigeria,  following previously described methods by other authors. The species are distributed across all geo-ecological zones of the country but more abundant in the southern area which is…

Family- and genus-level circumscription of ferns in the suborder Aspleniineae (eupolypods II) has long been controversial, due in part to confusion about the relationship among the families Aspleniaceae and Athyriaceae. Recent studies have demonstrated that character states traditionally used to inf…

A new species of Utricularia Section Orchidioides: Utricularia amotape-huancabambensis sp. nov. (Lentibulariaceae), endemic to Northern Peru is described and illustrated. It is known from two populations so far, both located in the Province Bongará, Dpto. Amazonas at ca. 2200 m altitude. The new spe…

Crop wild relatives (CWR) are an important agricultural resource as they contain genetic traits not found in cultivated species due to localised adaptation to unique environmental and climatic conditions. Phylogenetic Diversity (PD) measures the evolutionary relationship of species using the tree of…
