Escobar, S., Helmstetter, A. J., Montúfar, R., Couvreur, T. L. P., & Balslev, H. (2022). Phylogenomic relationships and historical biogeography in the South American vegetable ivory palms (Phytelepheae). Molecular Phylogenetics and Evolution, 166, 107314. doi:10.1016/j.ympev.2021.107314 https://doi.org/10.1016/j.ympev.2021.107314

The palm tribe Phytelepheae form a clade of three genera and eight species whose phylogenetic relationships and historical biogeography are not fully understood. Based on morphological similarities and phylogenetic relatedness, it has been suggested that Phytelephas seemannii and Phytelephas schotti…

Riibe, L., Sundue, M., Sessa, E., & Testo, W. (2021). A Reassessment of the Little-Known Amazonian Fern Diplazium praestans Based on Molecular and Morphological Evidence. Systematic Botany, 46(2), 260–272. doi:10.1600/036364421x16231782047451 https://doi.org/10.1600/036364421X16231782047451

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…

Henning, T., Allen, J. P., & Rodríguez Rodríguez, E. F. (2021). A new species of Utricularia Sect. Orchidioides (Lentibulariaceae) from the Amotape-Huancabamba Zone of North Peru. Darwiniana, Nueva Serie, 9(2), 299–311. doi:10.14522/darwiniana.2021.92.955 https://doi.org/10.14522/darwiniana.2021.92.955

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…

Chu, X., Gugger, P. F., Li, L., Zhao, J., & Li, Q. (2021). Responses of an endemic species ( Roscoea humeana ) in the Hengduan Mountains to climate change. Diversity and Distributions. doi:10.1111/ddi.13397 https://doi.org/10.1111/ddi.13397

Aim: Adaptation, migration and extinction of species is closely associated with climate changes and shape the distribution of biodiversity. The adaptive responses of species in the biodiversity hotspot, the Hengduan Mountains, to climate change remain poorly understood. Location: The Hengduan Mount…

Baumbach, L., Warren, D. L., Yousefpour, R., & Hanewinkel, M. (2021). Climate change may induce connectivity loss and mountaintop extinction in Central American forests. Communications Biology, 4(1). doi:10.1038/s42003-021-02359-9 https://doi.org/10.1038/s42003-021-02359-9

The tropical forests of Central America serve a pivotal role as biodiversity hotspots and provide ecosystem services securing human livelihood. However, climate change is expected to affect the species composition of forest ecosystems, lead to forest type transitions and trigger irrecoverable losses…

Lopes, A., Demarchi, L. O., Franco, A. C., Ferreira, A. B., Ferreira, C. S., Wittmann, F., … Piedade, M. T. F. (2021). Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems. Acta Botanica Brasilica. doi:10.1590/0102-33062020abb0188 https://doi.org/10.1590/0102-33062020abb0188

Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains…

Dellinger, A. S., Pérez‐Barrales, R., Michelangeli, F. A., Penneys, D. S., Fernández‐Fernández, D. M., & Schönenberger, J. (2021). Low bee visitation rates explain pollinator shifts to vertebrates in tropical mountains. New Phytologist. doi:10.1111/nph.17390 https://doi.org/10.1111/nph.17390

Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central for the evolution and diversification of angiosperms, w…

Evangelista-Vale, J. C., Weihs, M., José-Silva, L., Arruda, R., Sander, N. L., Gomides, S. C., … Eisenlohr, P. V. (2021). Climate change may affect the future of extractivism in the Brazilian Amazon. Biological Conservation, 257, 109093. doi:10.1016/j.biocon.2021.109093 https://doi.org/10.1016/j.biocon.2021.109093

The Amazon forest is vulnerable to climate change and anthropic actions, such as fire and deforestation, which together represent a troubling scenario. Many traditional populations that inhabit the region depend on non-timber forest resources for food or economic sustenance. We demonstrated that cli…

Da Cruz Vasconcelos, C., Ferraz, I. D. K., Adrianzén, M. U., Camargo, J. L. C., & Terra-Araujo, M. H. (2021). Chromolucuma brevipedicellata (Sapotaceae, Chrysophylloideae), a new tree species from central Amazonia, Brazil. Brittonia. doi:10.1007/s12228-021-09663-y https://doi.org/10.1007/s12228-021-09663-y

A new species from central Amazonia, Chromolucuma brevipedicellata (Sapotaceae, Chrysophylloideae) is described and illustrated. It occurs in terra firme (non-flooded) forests near Manaus, Brazil. We compare C. brevipedicellata to similar species in terms of diagnostic morphology, as well as near-in…

Lima, L. V., Oliveira, U., Almeida, T. E., Bueno, M. L., & Salino, A. (2021). Migration barriers in ferns: the case of the neotropical genus Diplopterygium (Gleicheniaceae). Plant Ecology & Diversity. doi:10.1080/17550874.2021.1890259 https://doi.org/10.1080/17550874.2021.1890259

Background: Despite the broad distribution of several species in Gleicheniaceae in the neotropical region, Diplopterygium is the only genus having a restricted distribution. Species of Gleicheniaceae occupy open (including anthropogenic) habitats and produce large amounts of wind-dispersed propagule…
