Two new synonyms and a species reinstated in Phoradendron Nuttall (Viscaceae) Dois novos sinônimos e uma espécie restabelecida em Phoradendron Nuttall (Viscaceae) [PDF]

Acta Botânica Brasílica, 2007
Three taxonomic changes are proposed based on intensive collecting of Viscaceae within the Distrito Federal, Brazil. Phoradendron andersonii Rizzini, previously a synonym of P. perrottetii (DC.) Eichler is reinstated based on the following combination of

Epiparasitism in Phoradendron durangense and P. falcatum (Viscaceae) [PDF]

Aliso, 2009
Phoradendron, the largest mistletoe genus in the New World, extends from temperate North America to temperate South America. Most species are parasitic on terrestrial hosts, but a few occur only, or primarily, on other species of Phoradendron. We examined relationships among two obligate epiparasites, P. durangense and P.

Range and Elevational Shifts of Mistletoes Under Future Climate Change Scenarios. [PDF]

Ecol Evol
Mistletoes are particularly vulnerable to climate change because of their obligate dependence on host plants. We investigated how climate change will alter the distribution of suitable habitat of Mesoamerican Psittacanthus mistletoes. Species differences were found in distribution with northward and upward shifts accompanied by significant range size ...

The best of two worlds: ecology and evolution of ambophilous plants

Biological Reviews, Volume 98, Issue 2, Page 391-420, April 2023., 2023
ABSTRACT Ambophily, the mixed mode of wind and insect pollination is still poorly understood, even though it has been known to science for over 130 years. While its presence has been repeatedly inferred, experimental data remain regrettably rare. No specific suite of morphological or ecological characteristics has yet been identified for ambophilous ...

Biological Flora of Britain and Ireland: Viscum album

Journal of Ecology, Volume 111, Issue 3, Page 701-739, March 2023., 2023
Mistletoe is a charismatic parasite of tree crowns with a long history of folklore and connections with Christmas celebrations. This, and its need for light, helps explain why it is most common in human‐made habitats across Europe. Once thought to benignly take just water and nutrients from its host it is now known to take carbon as well which can lead
