“…Development and application of the spatial model are discussed in White et al (1992) and Smith et al, (1993). Land use categories for the spatial model were determined through classification of Landsat Thematic Mapper data for August 1985 and level I and II Anderson classifications of 1:250,000 scale land use data compiled from high altitude aerial photographs taken in the early 1970s (Fegeas et al, 1983;Anderson et al, 1976); population estimates were obtained from the 1980 Census of Population and Housing (Lanfear, 1993).…”

“…Median concentrations were calculated for samples from 255 sites across New Jersey ( Figure 1B) for three classes of chlorinated organic compounds, and a binary response variable was set equal to 0 or 1 depending on whether the median concentration was below, or was equal to or exceeded, a specified concentration. Descriptions of, and summary statistics for, binary response variables for the three classes of chlorinated organic compounds are provided in Table 3. Explanatory variables examined during the course of this investigation, which were designed to characterize the type and degree of development within the drainage area of each sampling site, included total population, land use categories, total flow of Total population aggregated upstream with a decay factor of -1.0 (Lanfear, 1993 RES-3 Area of residential land (km2) aggregated upstream with a decay factor of -0.1 (Fegeas et al, 1983).

: Concentrations of 18 hydrophobic chlorinated organic compounds in streambed sediments from 100 sites throughout New Jersey were examined to determine (1) which compounds were detected most frequently, (2) whether detection frequencies differed among selected drainage basins, and (3) whether concentrations differed significantly among selected drainage basins. Twelve drainage basins across New Jersey that contain a range of land‐use patterns and population densities were selected to represent various types and degrees of development. To ensure an adequate number of samples for statistical comparison among drainage basins, the 12 selected basins were consolidated into seven drainage areas on the basis of similarities in land‐use patterns and population densities. Additionally, data for three classes of chlorinated organic compounds in streambed sediments from 255 sites throughout New Jersey were examined to determine whether the presence of these compounds in streambed sediments is related to the type and degree of development within the drainage area of each sampling site. Chlorinated organic compounds detected most frequently within the seven representative drainage areas were DDT, DDE, DDD, chlordane, dieldrin, and PCBs. DDT, DDE, and DDD, which were the most widely distributed organic compounds, were detected in about 60 to 100 percent of the samples from all drainage areas but one (where the detection rate for these compounds was about 20 to 40 percent). Chiordane and dieldrin were detected in about 80 to 100 percent of samples from highly urbanized and populated drainage areas; detection frequencies for these compounds tended to be smaller in less developed and populated areas. PCBs were detected in about 40 to 85 percent of samples from all drainage areas; detection frequencies were highest in the most heavily developed and populated areas. Analysis of variance on rank‐transformed organic compound concentrations normalized to sediment organic carbon content was used to evaluate differences in concentrations among the seven representative drainage areas. Chlordane and PCBs were the chlorinated organic compounds with the most highly elevated concentrations in streambed sediments across the State. Median normalized concentrations of all six of the most frequently detected chlorinated organic compounds were highest in the most heavily urbanized and populated drainage area and lowest in the less populated, predominantly agricultural or forested areas. Concentrations of DDT and DDE, however, did not differ significantly among most of the drainage areas. Concentrations of DDD, chlordane, dieldrin, and PCBs differed significantly among drainage areas. The highest median normalized concentrations were found in samples from the most heavily urbanized and populated areas, and the lowest were in samples from the least developed, most heavily forested area. Logistic regression was used to examine relations between the presence of hydrophobic chlorinated organic compounds in streambed sediments at specified con...

Context Remote sensing has been a foundation of landscape ecology. The spatial resolution (pixel size) of remotely sensed land cover products has improved since the introduction of landscape ecology in the United States. Because patterns depend on spatial resolution, emerging improvements in the spatial resolution of land cover may lead to new insights about the scaling of landscape patterns. Objective We compared forest fragmentation measures derived from very high resolution (1 m 2) data with the same measures derived from the commonly used (30 m 9-30 m; 900 m 2) Landsat-based data. Methods We applied area-density scaling to binary (forest; non-forest) maps for both sources to derive source-specific estimates of dominant (density C 60%), interior (C 90%), and intact (100%) forest. Results Switching from low-to high-resolution data produced statistical and geographic shifts in forest spatial patterns. Forest and non-forest features that were ''invisible'' at low resolution but identifiable at high resolution resulted in higher estimates of dominant and interior forest but lower estimates of intact forest from the high-resolution source. Overall, the high-resolution data detected more forest that was more contagiously distributed even at larger spatial scales. Conclusion We anticipate that improvements in the spatial resolution of remotely sensed land cover products will advance landscape ecology through reinterpretations of patterns and scaling, by fostering new landscape pattern measurements, and by testing new spatial pattern-ecological process hypotheses.
