“…In a previous study (Pereira et al 2012), we combined the suggestion of Shepherd & Litvak (2004) with the 3 constructs of habitat use identified by Petitgas (1998) to examine a population of yellowtail flounder Limanda ferruginea on the northeast coast of the United States. The combination resulted in the predictions summarized in Table 1.…”

Three theories of habitat use proposed for marine fishes, the constant density model (CDM), the proportional density model (PDM), and the basin model (BM), make contrasting predictions of how the range, local density, and fitness change as population size changes. We tested model predictions using a survey of silver hake Merluccius bilinearis conducted by the National Marine Fisheries Service every spring and fall. Data on fish length, sex, weight, and reproductive status are collected. Despite a 50% population reduction over the time period of the survey, the geographic area occupied by silver hake did not change significantly. Local density in preferred habitat remained a constant proportion of the entire population. Fitness (as indicated by individual condition) varied over a fine spatial scale, reflected in a pattern of spatial autocorrelation of 10s to 100s of kilometers. Fitness did not exhibit density dependence, except in one case, females in the fall, probably due to the higher energy needs of the females. The results indicate that silver hake conform to the PDM, a site-dependent model, and yet we found some evidence of density dependence in our measure of fitness. Site dependence may work in concert with density dependence to regulate population size. Sites silver hake depend on may be the spawning areas along the coast, which may already be in legislatively protected areas. Our study illustrates that an understanding of habitat use is important for crafting conservation or management measures that lead to maintenance of a stable population.

Abstract:With the continuous progress of human production and life, air quality has become the focus of attention. In this paper, Beijing, Tianjin, Hebei, Shanxi, Shandong and Henan provinces were taken as the study area, where there are 58 air quality monitoring stations from which daily and monthly data are obtained. Firstly, the temporal characteristics of the air quality index (AQI) are explored. Then, the spatial distribution of the AQI is mapped by the inverse distance weighted (IDW) method, the ordinary kriging (OK) method and the Bayesian maximum entropy (BME) method. Additionally, cross-validation is utilized to evaluate the mapping results of these methods with two indexes: mean absolute error and root mean square interpolation error. Furthermore, the correlation analysis of meteorological factors, including precipitation anomaly percentage, precipitation, mean wind speed, average temperature, average water vapor pressure and average relative humidity, potentially affecting the AQI was carried out on both daily and monthly scales. In the study area and period, AQI shows a clear periodicity, although overall, it has a downward trend. The peak of AQI appeared in November, December and January. BME interpolation has a higher accuracy than OK. IDW has the maximum error. Overall, the AQI of winter (November), spring (February) is much worse than summer (May) and autumn (August). Additionally, the air quality has improved during the study period. The most polluted areas of air quality are concentrated in Beijing, the southern part of Tianjin, the central-southern part of Hebei, the central-northern part of Henan and the western part of Shandong. The average wind speed and average relative humidity have real correlation with AQI. The effect of meteorological factors such as wind, precipitation and humidity on AQI is putative to have temporal lag to different extents. AQI of cities with poor air quality will fluctuate greater than that of others when weather changes and has higher correlation with meteorological factors.
