Whale Entanglements Disentangled Through The Lens Of Cumulative Habitat Compression, Jarrod A. Santora, Isaac D. Schroeder, Elliott L. Hazen, John C. Field, Karin A. Forney, Lauren Saez, Dan Lawson

Faculty Research, Scholarly, and Creative Activity

Ten years following a marine heatwave event, whale entanglements continue to challenge ecosystem-based fishery and protected species management in the California Current Large Marine Ecosystem (CCLME). Although new fishing regulations combined with environmental changes resulted in a decline in humpback whale (Megaptera novaeangliae) entanglements from the peak during a prolonged heatwave, reports continue at a higher rate than prior to 2014. The entanglement record is imperfect because many entanglements go unobserved and those that are observed may not correspond to where the entanglement occurred. Thus it remains a challenge to understand when and where entanglements are most likely to occur …

Women’S Reproductive Health Conditions And Fertility Goals, Karen Benjamin Guzzo, Kathleen Broussard

Faculty Publications

There is a large body of research examining women’s fertility decision-making. Yet this work rarely considers how women’s experiences with reproductive health conditions may be linked to their fertility goals, a problematic oversight given the growing emphases on reproductive careers and childbearing biographies that highlight the need to take a life course approach to fertility. Using the 2015–2019 National Survey of Family Growth (N = 8867), this paper examines how reproductive health conditions are associated with women’s fertility goals among women who are not surgically sterile or meet the medical definition of infertility.
