Distribution and dispersal of desert mistletoe is scale-dependent, hierarchically nested

Spatial patterns are important to many ecological processes, and scale is a critical component of both patterns and processes. I examined the pattern and scale of the spatial distribution of infection of host plants by the desert mistletoe, Phoradendron californicum, in a landscape that spans several square kilometers. I also studied the relationship between mistletoe infection and seed dispers...

7 Mistletoes as Parasites and Seed - dispersing Birds as Disease Vectors : Current Understanding , Challenges and Opportunities

Most mistletoes are vector-borne parasites whose vectors are their avian seed-dispersers (Martínez del Rio et al., 1996). In most vector-borne parasites and diseases, the vector maintains a parasitic or, at best, a commensal relationship with the parasite (Price, 1980). Mistletoes are unique among vector-borne parasites because they maintain a mutualistic interaction with their vectors (Martíne...

Two Epiparasitic Species of Phoradendron (Viscaceae) from Honduras: one New and for the Other a Range Extension and Host Determination

A new species of Phoradendron, Ph. mathiasenii, is described, and a range extension and host are given for Ph. tikalense. Both species are from Honduras and grow as epiparasites, i.e., mistletoes parasitizing other mistletoes. The parasitic host for both epiparasitic species of Phoradendron is Psittacanthus angustifolius (Loranthaceae), which in turn is parasitic on the terrestrial host, Pinus ...

A global analysis of water and nitrogen relationships between mistletoes and their hosts: broadscale tests of old and enduring hypotheses

1. Mistletoes use far more water per unit carbon fixed during photosynthesis than their hosts (i.e. they have lower ‘water use efficiency’, WUE). The widely cited ‘nitrogen-parasitism hypothesis’ posits that N is the most limiting resource for mistletoes and that they use their faster transpiration rates to acquire sufficient N from the host xylem. In a rather different context, the ‘mimicry hy...
