(1987) found that very few intact seed passed through the digestive systems of adult mourning doves and only a low amount of seeds, mainly Euphorbia esula, were recovered from faecal material found in dove nests, that is why they considered that this species of pigeon rarely acted as seed disperser.

Jatrophane diterpenes from Euphorbia esula as antiproliferative agents and potent chemosensitizers to overcome multidrug resistance.
Using NASA's advanced hyperspectral sensor, the Airborne Visible Infrared Imaging Spectrometer (AVIRIS), Raymond Hunt and colleagues have developed and tested a new method for locating leafy spurge (Euphorbia esula), a noxious invasive weed that causes more than $200 million a year in losses in the Great Plains and western United States.
Recent intrusions of exotic, invasive species are evident: Lythrum salicaria, purple loosestrife; Euphorbia esula, leafy spurge; and introduced genotypes of Phragmites australis, common reed.
For example, leafy spurge (Euphorbia esula) exposed experimentally to millimolar concentrations of HQ had reduced water uptake by leaves, resulting in closed stomata and decreased photosynthesis (1).
Sections of Euphorbia esula buds embedded in LR White or BMA were incubated with antibodies against actin and a-tubulin and with antibodies that recognize non-phosphorylated and phosphorylated peptides on a CDK activating kinase (CAK).
In this study, I test the hypothesis that introduced leafy spurge (Euphorbia esula L.: Euphorbiaceae; hereafter Euphorbia) competes for pollination with the native plant blue-eyed grass (Sisyrinchium campestre E.

Now Kremer says DRB may become the basis for a commercial bioherbicide against one of the worst weeds in the West: leafy spurge, Euphorbia esula. A Eurasian native, the weed now infests at least 29 states and costs 4 of them - Montana, Wyoming, and North and South Dakota - an estimated $144 million annually.
Research has shown that chronic exposure to HQ by leafy spurge (Euphorbia esula L.) disrupts plant-water relationships indicating the primary site of perturbation is in the root.
