The anatomy of a range expansion: changes in cranial morphology and rates of energy extraction for North American red squirrels from different latitudes

Article Abstract:

The differences in foraging behaviors and morphology relative to red squirrels from the central hardwoods and from the conifer-dominated environments are examined. The rates of energy extraction, variation in cranial morphology and diet preference between red squirrels from both regions are described.

Forces structuring tree squirrel communities in landscapes fragmented by agriculture: species differences in perceptions of forest connectivity and carrying capacity

Article Abstract:

The interspecific differences in mobility and sensitivity to habitat loss and modification by agriculture are investigated with the help of translocation experiments and patch occupancy data. The gray squirrels' display of inferior mobility relative to red and fox squirrels is examined.

Population consequences of movement decisions in a patchy landscape

Article Abstract:

The persistence of a species in a landscape consisting of habitat patches surrounded by more than one landscape type is examined. The factors affecting equilibrium population size and patterns of patch occupancy are described.
