A Preliminary Study of the Examination of the Macroinvertebrate Assemblage In Macy Park of the Saw Mill River above and below a drainage pipe

Abstract An urban stream was examined from June to August in 2014 to determine if the effluence exiting a stormwater drainage pipe affected the benthic and drift macroinvertebrate assemblages above and below the pipe. The distribution of macroinvertebrates was also compared above and below the pipe to determine the difference in composition. Statistical means were run to explore the data and to identify any significant correlations between the assemblages in relation to the pipe, month, […]

Effects of chemical pesticides on beneficial and harmful insect populations on four farms in Central Massachusetts

Abstract Finding sustainable methods to control pest insects that affect crop yield is a pressing, worldwide concern for agriculture. In recent decades, there has been interest in developing less toxic chemical pesticides, and more sparse regimens for application of these pesticides to avoid also killing beneficial insects during pesticide applications. For this study, insects were collected from four farms in Central Massachusetts (Middlesex and Worcester Counties) to compare the population levels of beneficial and harmful […]
