Abstract
Over a period of several years, pertinent data were gathered on the life histories of several species of mammals at Point Abino, Welland County, Ontario. Observations and collections were made from November 24-26 and December 24-26, 1939; April 2-6, 1940; March 30-April 3, 1941; and August 23-September 22, 1942, at this locality and at irregular intervals elsewhere in Welland County. Several of the typical habitats of this part of Ontario are represented in the immediate vicinity of Point Abino. The area considered is approximately 700 acres of which 75 percent is woodland, the remainder being grassland and beaches. The dominant woody vegetation is deciduous. Black oak (Quercus velutina), bitternut hickory (Carya cordiformis), black walnut (Juglans nigra), ironwoods (Ostrya virginiana and Carpinus caroliniana), beech (Fagus grandifolia), tulip tree (Liriodendron tulipifera), wild cherries (Prunus serotina, P. virginiana, and P. pennsylvanica), maples (Acer saccharum and A. rubrum), basswood (Tilia americana), white ash (Fraxinus americana), and white pine (Pinus strobus) and hemlock (Tsuga canadensis) are the trees most commonly seen. The dominant shrubs are spice bush (Lindera benzoin), witch-hazel (Hamamelis virginiana), dogwoods (Cornus stolonifera, C. racemosa, and C. aiternifolia), wild black current (Ribes americana), and arrow-woods (Viburnum dentatum, V. acerifolium, and V. trilobum). The area was trapped regularly, using small snap-back traps, steel traps, and live traps. The specimens were placed in white flannel bags immediately upon removal from the traps, and the fleas were saved for later identification. Stomachs were preserved in every instance and, although the numbers are insufficient for statistical analysis, they are used here to indicate the important food items. In preparation of this paper I have received guidance from Dr. Edward C. Raney. Dr. Duane Isely gave me much assistance in the identification of the botanical material.
