The mean lifetime reproductive success of the complete simulated population and the two different groups with increasing fixed heterogeneity for females

A winner of the Young Author Award 2021

Our article “Relative contributions of fixed and dynamic heterogeneity to variation in lifetime reproductive success in kestrels (Falco tinnunculus)" published in Population Ecology has been selected by the nomination committee of the Society of Population Ecology as an excellent paper.  It has been chosen as a winner of the Young Author Award 2021.

A course on chili peppers covers history, anthropology, biology, and culture, and includes a visit to a specialty pepper farm in East Palo Alto.

Lalita du Perron talks to Shripad “Tulja” Tuljapurkar, Professor of Biology at Stanford, about his work on demographics, his love of food, and his undergraduate class on the chili pepper.

Shripad Tuljapurkar was awarded the Sustainability Accelerator award for working on the research and social dimensions of wildlife conservation in the northwest Trans Himalaya. We believe human and natural capital are inextricably linked- not only through shared land-use and ecosystem services but also through their vulnerabilities to processes of change.

Bloomberg Getting old can be hard under any circumstances, and harder still when you’re poor. That’s the predicament for Thailand, the developing country first in line to face the consequences of a first-world-style baby bust. Data published last month by the United Nations show births in Thailand have dropped to a level on par with Switzerland and Finland, two ultra-wealthy countries with which it has almost nothing else in common.

Live Science Aging is determined by biological, not environmental, factors, a study suggests. No matter how hard you try, it might be difficult to slow down aging, a depressing new study suggests. Across a range of primate species, including humans, aging rates are mostly determined by biological factors, not environmental ones.

The New York Times The New York Times featured an article about our work on “The Dynamics of Phenotypic Change and the Shrinking Sheep of St. Kilda,” Ozgul, A., S. Tuljapurkar, T. G. Benton, J. M. Pemberton, T. H.Clutton-Brock and T. Coulson, published in Science (325, 464-467, 2009).

"What happens in 20 years?" Tuljapurkar asked the graduate students and postdoctoral fellows attending the workshop. "That is a frightening rate of decline (on fertility rates), especially in smaller countries."

The benefits of increased lifespans could come at the cost of greater societal burdens. Biologist says expectancy may soon be 100. People much older than Weinstein could become the norm, said Stanford University biology and demographics Professor Shripad Tuljapurkar. He believes medical advances in anti-aging technologies could increase Americans' average life expectancy in the near future from just under 80 years to 100. Society needs to consider the possibility, Tuljapurkar argues, because the implications for programs like Social Security are mind bending.
