We studied age-related antler characteristics of moose (Alces alces) in Alaska Game Management Unit 20A (during 2007–2010) because of concerns about poor antler development given the population’s high density and unusually low nutritional status.

A diverse, international Fortymile Planning Team wrote a novel Fortymile caribou herd {Rangifer tarandus granti) Management Plan in 1995 (Boertje & Gardner, 1996: 56-77). The primary goal of this plan is to begin restoring the Fortymile herd to its f

The Delta and Yanert caribou (Rangifer tarandus granti) herds apparently maintained discrete calving areas from 1979 through 1983 (as determined by radio telemetry studies), even though substantial intermixing occurred during other seasons. Also, the

Activity of female and young caribou in the Denali herd was studied from June 1978 through April 1980 to help assess the food availability/nutritional status of this reduced population. No nutritional stress was evident as inferred by the greater act

Understanding the limiting factors of a prey population is important before and during predator control programs, and optimal intensive management of an increasing prey population requires formal recognition of a sustainable population size. The migr

We sent 76 canines and 77 incisors (I1) from 84 known-age moose (Alces alces) ≥2 years old sampled from near Fairbanks, Alaska, USA (2003–2011) to Matson's Laboratory (Milltown, MT) to test G. Matson's accuracy rate in estimating moose ages. To e

We documented the temporal and demographic recovery of a black bear (Ursus americanus) population following a 2-year translocation program that substantially reduced both male and female bears. We estimated black bear population abundance prior to (2

We studied moose (Alces alces) survival, physical condition, and abundance in a 3-predator system in western Interior Alaska, USA, during 2001-2007. Our objective was to quantify the effects of predator treatments on moose population dynamics by inve

We present methodology for assessing browse removal to help evaluate resource limitation among moose Alces alces populations in large, potentially remote areas of boreal forest. During 2000-2007, we compared proportional removal (ratio of browse cons
