Background: Hate crimes against Muslim Americans have increased exponentially in the past 20 years, but there is currently no scale for measuring perceived anti-Muslim discrimination in the United States. To fill this gap, this study used a mixed-method approach to develop scales for measuring perceived anti-Muslim discrimination. Method: Qualitative data informed the development and validation of the 19-item Societal Anti-Muslim Discrimination Index and the 9-item Interpersonal Anti-Muslim Discrimination Index. Quantitative data ( N = 347) were collected from Muslim Americans using an online survey and used to assess the anti-Muslim indexes. Results: Qualitative data contributed to the refinement scale items. Quantitative results indicated one-component models and modest to high reliability of the Interpersonal Anti-Muslim Discrimination Index (.77) and Societal Anti-Muslim Discrimination Index (.88) scales. Discussion: Study results established the validity of these novel scales for measuring the distinct facets of anti-Muslim discrimination not captured by the Everyday Discrimination Index. These scales will facilitate research on anti-Muslim discrimination and the health implications of this form of religious-based discrimination.

Gray Seals

Although it is often assumed that individuals in generalist populations are equivalent, recent research indicates that individual dietary specialization can be common in marine predators. Gray seals (Halichoerus grypus (Fabricius, 1791)) were considered locally extinct in United States waters by 1958 but have since recolonized the region. Although considered generalists, less is known about gray seal foraging ecology in the United States. To address this, we used carbon and nitrogen stable isotope analyses to investigate the foraging niches of adult gray seals in Massachusetts, USA. We examined skin, fur, and blood components to investigate seasonal variability and individual consistency in foraging niches, and serially sampled vibrissae to quantify the degree of individual foraging specialization in this population. Our results suggest that seals shift from coastal foraging habitats before molt to offshore habitats after molt, with a coincident shift from higher to lower trophic-level prey. Adult gray seals also exhibited individual consistency in foraging niches independent of population-level shifts and reflect a generalist population composed of individual foraging specialists. These findings serve as a baseline for subsequent research on gray seals in United States waters that could help to determine the mechanisms which promote individual specialization in this population.
