Annual Arctic Wolf Pack Size Related To Arctic Hare Numbers, L. David Mech

USGS Northern Prairie Wildlife Research Center

During the summers of 2000 through 2006, I counted arctic wolf (Canis lupus arctos) pups and adults in a pack, arctic hares (Lepus arcticus) along a 9 km index route in the area, and muskoxen (Ovibos moschatus) in a 250 km² part of the area near Eureka (80° N, 86° W), Ellesmere Island, Nunavut, Canada. Adult wolf numbers did not correlate with muskox numbers, but they were positively related (r² = 0.89; p < 0.01) to an arctic hare index. This is the first report relating wolf numbers to non-ungulate prey.

Pendant les étés 2000 à 2006, j’ai compté les jeunes loups arctiques et les adultes (Canis lupus arctos …

Possible Use Of Foresight, Understanding, And Planning By Wolves Hunting Muskoxen, L. David Mech

USGS Northern Prairie Wildlife Research Center

On Ellesmere Island in 2006, arctic wolves (Canis lupus arctos) were observed making a two-pronged approach to a herd of muskoxen (Ovibos moschatus) and, on another occasion, ambushing muskoxen. Both observations seemed to provide evidence that the wolves were using foresight, understanding, and planning. Although the possible use of insight and purposiveness has been documented in captive wolves, the present report is one of the few to document the possibility that freeranging wolves use these other three mental processes.

En 2006, sur l’île Ellesmere, des loups arctiques (Canis lupus arctos) ont été observés en …

Grotius, Ocean Fish Ranching, And The Public Trust Doctrine: Ride 'Em Charlie Tuna, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

Seventy percent of the world's fish populations are in serious decline; some have been fished to near extinction. While domestic and international efforts are underway to curb the rate at which the remaining fish are being depleted, the demand for fish appears to be outstripping these initiatives--before they can take hold, the fish may be gone. In response to this increasingly dire situation, many countries, including the United States, have turned to fish farming in hope of taking pressure off of certain wild stocks of fish while still meeting consumer demands for them. More recently, non-U.S. fish farmers have moved …

Administering The Clean Water Act: Do Regulators Have "Bigger Fish To Fry" When It Comes To Addressing The Practice Of Chumming On The Chesapeake Bay?, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

The Chesapeake Bay is one of the country's most productive estuaries. However, for decades the health of the Bay has been declining due in large part to nutrification. Excessive nutrients encourage algal blooms, which lower dissolved oxygen and increase turbidity in the Bay's waters. More than 40% of the Bay's main stern is now dead largely as a result of this problem. The practice of chumming, the discarding of baitfish, usually menhaden, over the sides of fishing boats to attract game fish like striped bass, is contributing to the Bay's nutrification problem because the decomposing chum raises the waters biological …
