From leaves to the whole tree: Mistletoe effects on the productivity, water relations, and demography of a Neotropical savanna tree

open access: yesAustral Ecology, Volume 49, Issue 2, February 2024.
Abstract Trees' responses to mistletoes occur at multiple organization levels (e.g., leaf, individual, population), yet integrating these multi‐scale responses is still challenging. Here, we compared the traits of infected versus uninfected trees over multiple scales, from leaf anatomy and physiology to canopy allometries and individual growth rate and

What explains the high island endemicity of Philippine Rafflesia? A species distribution modeling analysis of three threatened parasitic plant species and their hosts

open access: yesAmerican Journal of Botany, Volume 111, Issue 1, January 2024.
Abstract Premise Rafflesia are rare holoparasitic plants. In the Philippines, all but one species are found only on single islands. This study aimed to better understand the factors contributing to this distributional pattern. Specifically, we sought to determine whether narrow environmental tolerances of host and/or parasite species might explain ...

Epi‐parasitic mistletoes don't parasitise their host's host and this supports the immunity hypothesis for host choice

open access: yesAfrican Journal of Ecology, Volume 62, Issue 1, January 2024.
Abstract Mistletoes have much higher transpiration rates than their hosts. This is the basis for the ecological “compatibility hypothesis” for host choice. The inability of mistletoes to penetrate a host and connect to its vascular system is the competing “immunity hypothesis”.

Különböző szisztémikus herbicidek fehér fagyöngy (Viscum album) elleni hatékonyságának, illetve a fagyöngy hiperparazita kórokozójára gyakorolt antifungisztatikus hatásának vizsgálata [PDF]

open access: yes, 2012
There are more than 3000 ha in Hungary infected by European mistletoe (Viscum album L.), which have currently raised. The only way to control this hemiparasite is to cut down the infected branches, while other effective control methods are unknown.
