Fish hosts for four species of freshwater mussels (Pelecypoda: Unionidae) in the upper Tennessee River drainage.
January 1, 1995... INTRODUCTION
The decline or recent extinction of several species of Epioblasma (=Dysnomia = Plagiola) and Quadrula spp. indicates a synecological problem between these taxa of freshwater mussels and changes in North American rivers and...
Temporal variation in abundance of peromyscus leucopus in wooded habitats of eastern Kansas.
January 1, 1995... INTRODUCTION
During the last 10-20 yr, ecologists have directed increasing efforts at establishing long-term studies of plant and animal populations in both natural and disturbed ecosystems (Franklin, 1989; Franklin et al., 1990). Long-term...
White-tailed deer foraging in relation to successional stage, overstory type and management of Southern Appalachian forests.
January 1, 1995... INTRODUCTION
Until recently there has been a common assumption that basic relationships of white-tailed deer (Odocoileus virginianus) to their food resources in the Southern Appalachians are sufficiently well understood for sound management;...
Analysis of coyote predation on deer and elk during winter in Yellowstone National Park, Wyoming.
January 1, 1995... INTRODUCTION
Coyote (Canis latrans) predation has been documented on neonatal (i.e., [less than or equal to] 3 mo old) ungulates, including mule deer (Odocoileus hemionus) fawns (MacConnell-Yount and Smith, 1978; Hamlin and Schweitzer, 1979;...
Abundance of pitcher-plant mosquitoes, Wyeomyia smithii (Coq.) (Diptera: Culicidae) and midges, Metriocnemus knabi Coq. (Diptera: Chironomidae), in relation to pitcher characteristics of Sarracenia purpurea L.
January 1, 1995... INTRODUCTION
Larvae of the pitcher-plant mosquito (Wyeomyia smithii (Coq.)) and a midge (Metriocnemus knabi Coq.) commonly inhabit the aquatic environment in pitchers of the northern pitcher plant (Sarracenia purpurea L.). The female of both...
Acclimation and adaptive behavior of Drosophila robusta and D. tripunctata adults in response to combined temperature and desiccation stress.
January 1, 1995... INTRODUCTION
Natural populations are exposed to substantial physical stresses (Parsons, 1993b). These stresses are important in many ecological and evolutionary situations (Parsons, 1993a) including determining species distribution and...
Spider arrival and primary establishment on terrain depopulated by volcanic eruption at Mount St. Helens, Washington.
January 1, 1995... INTRODUCTION
Dispersal and colonization are key factors in both theoretical and experimental studies of island biogeography (MacArthur and Wilson, 1967; Simberloff and Wilson, 1970; Rey, 1981; Schoener and Spiller, 1987) and metapopulation...
Physiological and morphological attributes of two colonizing plant species on Mount St. Helens.
January 1, 1995... INTRODUCTION
The 1980 eruption of Mount St. Helens created a natural laboratory for studying successional processes, particularly due to the wide scale and diversity of disturbance that accompanied the eruption. A number of studies have...
Relict eastern white pine (Pinus strobus L.) stands in southwestern Wisconsin.
January 1, 1995... INTRODUCTION
In southwestern Wisconsin, close to the southern limit of its range, eastern white pine (Pinus strobus L.) grows in isolated stands on steep slopes of exposed Ordovician St. Peter sandstone and Cambrian sandstone of the Tunnel...
A comparison of limber pine (Pinus flexilis) ages at lower and upper treeline sites east of the Continental Divide in Colorado.
January 1, 1995... INTRODUCTION
A series of isolated conifer woodlands occupy an escarpment on the western Great Plains that stretches from Pine Bluffs, Wyoming, to Pawnee Buttes, Colorado. Nearly 100 km of grasslands separate these woodlands from the forests...
Safe sites and the regeneration of Clethra alnifolia L. (Clethraceae) in wetland forests of central New Jersey.
January 1, 1995... INTRODUCTION
Shrub species form an important but little understood component of many forested wetland communities (Schlesinger, 1978; Huenneke, 1987) determining the distinctive physiognomy of swamp systems (Ehrenfeld and Gulick, 1981)....
Seedling distribution and potential persistence of the exotic shrub Lonicera maackii in fragmented forests.
January 1, 1995... INTRODUCTION
Invasion of forests by exotic trees and shrubs is well-documented in many geographic areas (Myers, 1983; Luken, 1988; Harrington et al., 1989; Huenneke and Vitousek, 1990; Woods, 1993). Because most of these biological invasions...
The fitness cost of triazine resistance in jimsonweed (Datura stramonium L.)
January 1, 1995... INTRODUCTION
Herbicide resistance is an inherited ability of a plant to survive an application of herbicide at its labeled use rate (Gressel, 1991). Herbicides are the principal form of weed control in many crop production systems, and...
Density and seed production of a Florida endemic, Polygonella basiramia, in relation to time since fire and open sand.
January 1, 1995... INTRODUCTION
In pyrogenic shrub-dominated ecosystems (e.g., Florida scrub, California chaparral, Australian heath), plant species share several characteristics that may be vital to their continued existence (Noble and Slayter, 1977, 1980;...
Vegetation recovery following high-intensity wildfire and silvicultural treatments in sand pine scrub.
January 1, 1995... INTRODUCTION
Efforts to maintain the intergrity of natural community biodiversity are bringing ecosystem management to the forefront of conservation biology (Kessler, 1992). Special attention is directed toward national forests as potential...
Do artificial song-perches affect habitat use by grassland birds in Maine?
January 1, 1995... INTRODUCTION
Absence of adequate song-perches has been considered an important factor that may limit use of potential habitat by open country and grassland birds (Zimmerman, 1971; Wiens, 1973; Knodel-Montz, 1981). Presumably, the absence of...
The potential of the bull chub (Nocomis raneyi) as a predator of the zebra mussel (Dreissena polymorpha) in mid-Atlantic coastal rivers.
January 1, 1995... INTRODUCTION
The zebra mussel, (Dreissena polymorpha), introduced in North America from Europe via international shipping in the 1980s, has become established in the Great Lakes region, and is likely to spread throughout much of North...
Size-related habitat use by longnose dace (Rhinichthys cataractae).
