| Popis: | The purpose of this study was to identify spiders associated with foliage of sugar maple, Acer saccharum Marsh. and white ash, Fraxinus americana L., and to investigate their distribution and relative abundance within the crowns of these two northern hardwoods. Spiders were collected during June through August 1995 from the lower and mid-crowns of ten dominant/codominant sugar maples, five white ash and understory sapling and herbaceous foliage ≤2 m from the ground in a northern hardwood stand in Cortland County New York. These samples were compared for differences in species composition and density (number/25 leaf-clusters; number/100 g dry leaf weight). The spider fauna obtained from this intensive sample was compared to that of an extensive, 20-year survey from the mid-crown of sugar maple in 15 northern hardwood stands in northern New York (St. Lawrence and Lewis Counties). The intensive overstory collection (1995) from maple provided 694 specimens (7 families, 11 genera, 13 species). The dom... |
