Smith, A. L., Hodkinson, T. R., Villellas, J., Catford, J. A., Csergő, A. M., Blomberg, S. P., … Buckley, Y. M. (2020). Global gene flow releases invasive plants from environmental constraints on genetic diversity. Proceedings of the National Academy of Sciences, 117(8), 4218–4227. doi:10.1073/pnas.1915848117 https://doi.org/10.1073/pnas.1915848117

When plants establish outside their native range, their ability to adapt to the new environment is influenced by both demography and dispersal. However, the relative importance of these two factors is poorly understood. To quantify the influence of demography and dispersal on patterns of genetic div…

Howard, C. C., & Cellinese, N. (2020). Tunicate bulb size variation in monocots explained by temperature and phenology. Ecology and Evolution. doi:10.1002/ece3.5996 https://doi.org/10.1002/ece3.5996

Plant bulbs are modified shoot systems comprised of short internodes with apical bud(s) surrounded by layers of leaf bases. Bulb diameters can vary greatly, with overall bulb size playing a role in flower formation and resource allocation. Despite the importance of bulb size to the overall fitness o…

Oyedeji Amusa, M. O., Van Wyk, B.-E., & Oskolski, A. (2020). Wood anatomy of South African Meliaceae: evolutionary and ecological implications. Botanical Journal of the Linnean Society. doi:10.1093/botlinnean/boaa010 https://doi.org/10.1093/botlinnean/boaa010

Wood structure in seven South African species of Ekebergia, Nymania, Trichilia and Turraea (Meliaceae) was studied and compared with data for other genera of the subfamily Melioideae to elucidate phylogenetic relationships and pathways of trait evolution in this group and to clarify the ecological s…

Bhattacharya, E., Bose, R., & Mandal Biswas, S. (2019). A comprehensive study on occurrence records of African neglected and underutilized weed species, Cleome gynandra L. (cat’s whiskers) validating the ecogeographical range expansion in West Bengal, India. Weed Biology and Management, 19(4), 129–134. doi:10.1111/wbm.12189 https://doi.org/10.1111/wbm.12189

Cleome gynandra L., commonly known as cat’s whiskers, is an erect, branched, annual herb, belonging to the family Cleomaceae. The species is thought to have originated in tropical Africa and Southeast Asia, and thereafter have spread to other tropical and subtropical countries in the Northern and So…

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 …

Armani, M., Charles-Dominique, T., E. Barton, K., & W. Tomlinson, K. (2019). Developmental constraints and resource environment shape early emergence and investment in spines in saplings. Annals of Botany. doi:10.1093/aob/mcz152 https://doi.org/10.1093/aob/mcz152

Background and Aims: Herbivory by large mammals imposes a critical recruitment bottleneck on plants in many systems. Spines defend plants against large herbivores and how early they emerge in saplings may be one of the strongest predictors of sapling survival in herbivore-rich environments. Yet litt…

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.…

De Albuquerque, F. S., Macías-Rodríguez, M. Á., Búrquez, A., & Astudillo-Scalia, Y. (2019). Climate change and the potential expansion of buffelgrass (Cenchrus ciliaris L., Poaceae) in biotic communities of Southwest United States and northern Mexico. Biological Invasions. doi:10.1007/s10530-019-02050-5 https://doi.org/10.1007/s10530-019-02050-5

In the last decades, more than six hundred exotic species have become established throughout the region of the southwestern United States and northwestern Mexico, including the African buffelgrass (Cenchrus ciliaris L.). Buffelgrass often causes negative impacts on natural ecosystems and it is consi…

Jinga, P., & Ashley, M. V. (2019). Climate change threatens some miombo tree species of sub-Saharan Africa. Flora, 257, 151421. doi:10.1016/j.flora.2019.151421 https://doi.org/10.1016/j.flora.2019.151421

Climate change is affecting the distribution of species globally. Predicting the distribution of species under climate change is important for conservation of biodiversity. The aim of this research was to model the current distribution of miombo woodlands of sub-Saharan Africa using seventeen miombo…

Schubert, M., Marcussen, T., Meseguer, A. S., & Fjellheim, S. (2019). The grass subfamily Pooideae: Cretaceous–Palaeocene origin and climate‐driven Cenozoic diversification. Global Ecology and Biogeography. doi:10.1111/geb.12923 https://doi.org/10.1111/geb.12923

Aim: Frost is among the most dramatic stresses a plant can experience, and complex physiological adaptations are needed to endure long periods of sub‐zero temperatures. Owing to the need to evolve these complex adaptations, transitioning from tropical to temperate climates is regarded as difficult. …
