Faculty Profile


Dr. Krzyszczyk is a broadly trained behavioral ecologist passionate about science, nature and education outreach. She has channeled these interests into a career addressing the development of juvenile mammals, with a particular interest in using a diverse set of approaches whilst developing new ones. She is also committed to providing learning and training opportunities for the next generation and has frequently involved high school and college students in her research. Originally from the UK with roots deeply entrenched in Polish tradition, she moved to warmer climates and now has over 12 years of environmental research experience in many tropical areas around the globe.

Prior to joining SFS, Dr. Krzyszczyk pursued postdoctoral and graduate research in biology at Georgetown University, working in Shark Bay, Western Australia, to understand cetacean evolution and life history, using behavior, for conservation purposes. Global warming, noise and chemical pollution, bycatch, and reduced prey due to overfishing are just some of the grave threats that continue to threaten the existence of many cetaceans, and some threats are worsening. Cetacean diversity is crumbling—it is being lost in a rapid and increasing rate. Research on cetaceans has increased in response resulting in improved policies. However the juvenile period is still a relatively neglected area of research, the policies that are currently implemented (using calf or adult data) are likely not as effective for this age group and therefore the population. With this in mind, my research has examined this period of extended immaturity (8+ years) in bottlenose dolphins, to better understand changes in development and proximate and ultimate causes of an extended juvenile period, using a diverse set of approaches: physiological and hormonal development, age- and sex-specific survival, behavior and relationships. Results revealed that juveniles are challenged in distinctively different ways than adults or calves, crucial information to protect this age group differently to that of adults or calves. Her research has taken the first step in bridging the gap of knowledge between the calf and adult periods in bottlenose dolphins, and produced important baseline data for this relatively neglected age group, essential for future comparisons and ongoing conservation management.
