Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski
Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski
Massachusetts GIS Day
Mammal diversity varies in different types of land uses. Residential land use oftentimes interferes with the natural occurrence of mammal species. This study conducts a correlational analysis using camera trap data from Excel and land use data in GIS to uncover whether humans have disrupted mammal occurrence in residential land use areas in Amherst, MA. Results reveal that human activity in residential land use areas in Amherst did not strongly influence the occurrence of these mammals.

In the 1950s, Professor William P. MacConnell from the University of Massachusetts Forestry Department began working with his students to map the land cover in Massachusetts via the state’s earliest aerial photography program. These individual photographs are now part of the Special Collections and University Archives at the University of Massachusetts Amherst Libraries, and although they have been digitized and made available online, they have not yet been georeferenced.
In Spring 2021, our team (Alex and Matthew) began manually georeferencing the photos in ArcMap 10.8 software onto USGS 2019 color orthoimagery of Massachusetts available from MassGIS. Ideal ground control points …

We document the first New England records of the bee Perdita bequaerti Viereck. Perdita bequaerti is a specialist on Asteraceae flowers, especially Helianthus, and is native to much of eastern North America, where it is often associated with predominantly sandy habitats. Previous records indicated P. bequaerti reached the northeastern extent of its range in the state of New York, but in August 2019, during a survey of bees on Helianthus, we collected five specimens of P. bequaerti at two sites in western Massachusetts. Both sites were located on small-scale farms with abundant non-native Helianthus, on soils characteristic …
