White phosphorus at Eagle River Flats, Alaska: A case history of waterfowl mortality White phosphorus at Eagle River Flats, Alaska: A case history of waterfowl mortality
White phosphorus has a limited distribution in the environment because it only occurs where it has been directly used by humans. It is not transported aerially for any distance and, due to its density, has a limited ability to disperse through water. Therefore, it is not a contaminant of broad-scale concern. However, where it does occur, it can cause substantial mortality or critically...

Wolf population dynamics Wolf population dynamics
A large, dark wolf poked his nose out of the pines in Yellowstone National Park as he thrust a broad foot deep into the snow and plowed ahead. Soon a second animal appeared, then another, and a fourth. A few minutes later, a pack of thirteen lanky wolves had filed out of the pines and onto the open hillside. Wolf packs are the main social units of a wolf population. As numbers of wolves...

Wolf social ecology Wolf social ecology
The first real beginning to our understanding of wolf social ecology came from wolf 2204 on 23 May 1972. State depredation control trapper Lawrence Waino, of Duluth, Minnesota, had caught this female wolf 112 km (67 mi) south of where L. D. Mech had radio-collared her in the Superior National Forest 2 years earlier. A young lone wolf, nomadic over 100 km2 (40 mi2) during the 9 months...

Wolf-prey relations Wolf-prey relations
As I (L.D. MECH) watched from a small ski plane while fifteen wolves surrounded a moose on snowy Isle Royale, I had no idea this encounter would typify observations I would make during 40 more years of studying wolf-prey relations. My usual routine while observing wolves hunting was to have my pilot keep circling broadly over the scene so I could watch the wolves’ attacks without...

Water depth tolerances of dominant tree island species: What do we know? Water depth tolerances of dominant tree island species: What do we know?
Common woody species growing on tree islands in the Water Conservation Areas of South Florida include redbay, sweetbay, coastal-plain willow, wax myrtle, dahoon holly, cocoplum, pond-apple, red maple, cypress, gumbo-limbo, strangler fig and buttonbush. Very little is known about the flooding tolerance of most of these species. In this paper, we review flooding impact studies, describe...
