I'm confused, are glucosinolates toxic to animals?

I'm confused, are glucosinolates toxic to animals?

According to this PDF: https://www.na.fs.fed.us/FHP/invasive_p ... itetop.pdf, "The species also contains compounds of glucosinolates, which can be toxic to some animals."
(Disclaimer: I don't know anything about glucosinolates other than that)

Oh, Ok, thanks

I'll start this up again sorry meteorology891..


1) Common name
2) What stage of growth is this in?
3) What species are similar?
3) How do you distinguish this stage from other species of the same stage?
4) How do you distinguish the adult stage from other species as adults?
5) Best method of control?

Canada Thistle
Rosettes
The spiny leaves
Thin head, straight up (as opposed to "nodding" musk thistle), tubular florets
I believe it depends on the stage, but two possibilities are weevils and herbicides

I believe it also depends on the environment and the number of native species nearby before you spray the herbicide. I might be wrong though...

reviving this topic.

1.Damage from what insect is shown here?
2. What order does this insect belong to (common or scientific) ?
3. Explain two effects this insect has had in the eastern united states.
4. What close relative of this insect has been responsible for the demise of Fraser fir (Abies fraseri) in its native range of Southern Appalachian spruce–fir forest?

[Jaol]

1. Hemlock Wooly Adelgid
2. Hemiptera
3.Kills trees; lesser habitats for birds etc.
4. I have no idea...

1 yep
2 hemiptera or true bugs
3 demise of Tsuga canadensis and caroliniana which is detrimental to the timber industry. elimination of hemlock also leads to brightening of ravines, and the resulting sunlight warms the water many species are dependent on, such as brook trout.
