Which are stronger pound for pound Herbivores or Carnivores?

Great Bear Almanac by Gary Brown - Strength.
Bears possess enormous strength, regardless of species or size. The strength of a bear is difficult to measure, but observations of bears moving rocks, carrying animal carcasses, removing large logs from the side of a cabin, and digging cavernous holes are all indicative of enormous power. No animal of equal size is as powerful. A bear may kill a moose, elk, or deer by a single blow to the neck with a powerful foreleg, then lift the carcass in its mouth and carry it for great distances.
"The strength... is in keeping with size," describes Ben East in 'Bears'. "He is very powerfully built, a heavy skeleton overlaid with thick layers of muscle as strong as rawhide rope. He can hook his long, grizzly-like front claws under a slab of rock that three grown men could not lift, and flip it over effortlessly..." "...a brown bear took a thousand-pound steer a half mile up an almost vertical mountain, much of the way through alder tangles with trunks three or four inches thick." 
Strength and power are not only the attributes of large bears but also of the young. The author observed a yearling American black bear, while searching for insects, turn over a flat-shaped rock ( between 310 and 325 pounds ) "backhanded" with a single foreleg. The bear was captured the following day in a management action and weighed 120 pounds. 
( in my own words )... I'm sure that when the author says: "No animal of equal size is as powerful" he was referring to land-based mammals. Unlike these online blog-sites, such explanations are unnecessary as common sense applies. In my own opinion, no land-based mammal of equal size is stronger than a bear and no other bear species is pound-for-pound as strong as a grizzly. Understand though that measuring strength among different animal species is ( like measuring intelligence ) not an exact science. All any of us can do is to voice our opinion - which should however be backed by at least some sound reasoning. Reply
