Chevalier, M., B. M. Chase, L. J. Quick, L. M. Dupont, and T. C. Johnson. 2020. Temperature change in subtropical southeastern Africa during the past 790,000 yr. Geology 49: 71–75. 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…

Li, M., J. He, Z. Zhao, R. Lyu, M. Yao, J. Cheng, and L. Xie. 2020. Predictive modelling of the distribution of Clematis sect. Fruticella s. str. under climate change reveals a range expansion during the Last Glacial Maximum. PeerJ 8: e8729. https://doi.org/10.7717/peerj.8729

Background The knowledge of distributional dynamics of living organisms is a prerequisite for protecting biodiversity and for the sustainable use of biotic resources. Clematis sect. Fruticella s. str. is a small group of shrubby, yellow-flowered species distributed mainly in arid and semi-arid areas…

Ortiz-Rodriguez, A. E., Y. Licona-Vera, A. A. Vásquez-Aguilar, M. Hernández-Soto, E. A. López-Huicochea, and J. F. Ornelas. 2020. Genetic differentiation among Psittacanthus rhynchanthus (Loranthaceae) populations: novel phylogeographic patterns in the Mesoamerican tropical lowlands. Plant Systematics and Evolution 306. https://doi.org/10.1007/s00606-020-01638-y

Historical geological events and climatic changes have played important roles in shaping population differentiation and distribution within species. In this study, we analysed the distribution, expansion and colonization patterns, and genetic differentiation among Psittacanthus rhynchanthus populati…

VÁZQUEZ-GARCÍA, J.-A., D. A. NEILL, V. SHALISKO, F. ARROYO, and R. E. MERINO-SANTI. 2018. Magnolia mercedesiarum (subsect. Talauma, Magnoliaceae): a new Andean species from northern Ecuador, with insights into its potential distribution. Phytotaxa 348: 254. https://doi.org/10.11646/phytotaxa.348.4.2

Magnolia mercedesiarum, a new species from the eastern slopes of the Andes in northern Ecuador, is described and illustrated, and a key to Ecuadorian Magnolia (subsect. Talauma) is provided. This species differs from M. vargasiana in having broadly elliptic leaves that have an obtuse base vs. suborb…
