Meller, P., M. Stellmes, A. Fidelis, and M. Finckh. 2022. Correlates of geoxyle diversity in Afrotropical grasslands. Journal of Biogeography 49: 339–352. https://doi.org/10.1111/jbi.14305
Aim: Tropical old-growth grasslands are increasingly acknowledged as biodiverse ecosystems, but they are understudied in many aspects. Geoxyle species are a key component in many of these ecosystems, their belowground storage organs and bud banks are functionally diverse and contribute to the grassl…
de Deus Vidal, J., P. C. le Roux, S. D. Johnson, M. te Beest, and V. R. Clark. 2021. Beyond the Tree-Line: The C3-C4 “Grass-Line” Can Track Global Change in the World’s Grassy Mountain Systems. Frontiers in Ecology and Evolution 9. https://doi.org/10.3389/fevo.2021.760118
von Humboldt’s tree-line concept has dominated mountain ecology for almost two hundred years, and is considered a key indicator for monitoring change in biome boundaries and biodiversity shifts under climate change. Even though the concept of life zones and elevation gradients are a globally observe…
Vasconcelos, T., J. D. Boyko, and J. M. Beaulieu. 2021. Linking mode of seed dispersal and climatic niche evolution in flowering plants. Journal of Biogeography. https://doi.org/10.1111/jbi.14292
Aim: Due to the sessile nature of flowering plants, movements to new geographical areas occur mainly during seed dispersal. Frugivores tend to be efficient dispersers because animals move within the boundaries of their preferable niches, so seeds are more likely to be transported to environments tha…
Oh, D., K. P. Kowalski, Q. N. Quach, C. Wijesinghege, P. Tanford, M. Dassanayake, and K. Clay. 2021. Novel genome characteristics contribute to the invasiveness of Phragmites australis (common reed). Molecular Ecology 31: 1142–1159. https://doi.org/10.1111/mec.16293
The rapid invasion of the non-native Phragmites australis (Poaceae, subfamily Arundinoideae) is a major threat to native wetland ecosystems in North America and elsewhere. We describe the first reference genome for P. australis and compare invasive (ssp. australis) and native (ssp. americanus) genot…
Cahen, D., J. Rickenback, and T. M. A. Utteridge. 2021. A revision of Ziziphus (Rhamnaceae) in Borneo. Kew Bulletin 76: 767–804. https://doi.org/10.1007/s12225-021-09970-3
The genus Ziziphus (Rhamnaceae) is revised for Borneo. 13 species are recognised using morphological evidence, including three new endemic species: Ziziphus cuspidata, Z. domatiata and Z. puberula. Borneo is therefore the island with the greatest known diversity of Ziziphus species. The area surroun…
Xue, T., S. R. Gadagkar, T. P. Albright, X. Yang, J. Li, C. Xia, J. Wu, and S. Yu. 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. 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…
Culshaw, V., M. Mairal, and I. Sanmartín. 2021. Biogeography Meets Niche Modeling: Inferring the Role of Deep Time Climate Change When Data Is Limited. Frontiers in Ecology and Evolution 9. https://doi.org/10.3389/fevo.2021.662092
Geographic range shifts are one major organism response to climate change, especially if the rate of climate change is higher than that of species adaptation. Ecological niche models (ENM) and biogeographic inferences are often used in estimating the effects of climatic oscillations on species range…
Culshaw, V., T. Villaverde, M. Mairal, S. Olsson, and I. Sanmartín. 2021. Rare and widespread: integrating Bayesian MCMC approaches, Sanger sequencing and Hyb‐Seq phylogenomics to reconstruct the origin of the enigmatic Rand Flora genus Camptoloma. American Journal of Botany 108: 1673–1691. https://doi.org/10.1002/ajb2.1727
Premise: Genera that are widespread, with geographically discontinuous distributions and represented by few species, are intriguing. Is their achieved disjunct distribution recent or ancient in origin? Why are they species-poor? The Rand Flora is a continental-scale pattern in which closely related …
Rhodes, A. C., R. M. Plowes, J. A. Goolsby, J. F. Gaskin, B. Musyoka, P.-A. Calatayud, M. Cristofaro, et al. 2021. The dilemma of Guinea grass (Megathyrsus maximus): a valued pasture grass and a highly invasive species. Biological Invasions 23: 3653–3669. https://doi.org/10.1007/s10530-021-02607-3
On a global scale, invasive grasses threaten biodiversity and ecosystem function. Nevertheless, the importation of forage grasses is a significant economic force driven by globalization. Pastureland and rangeland are of critical economic and ecological importance, but novel grass species may lead to…
Archibald, S., W. Twine, C. Mthabini, and N. Stevens. 2021. Browsing is a strong filter for savanna tree seedlings in their first growing season. Journal of Ecology 109: 3685–3698. https://doi.org/10.1111/1365-2745.13745
Newly germinated seedlings are vulnerable to biomass removal but usually have at least six months to grow before they are exposed to dry-season fires, a major disturbance in savannas. In contrast, plants are exposed to browsers from the time they germinate, making browsing potentially a very powerfu…
