What happens after a forest dies, a coral reef bleaches, or an oyster bed collapses? A study of 10 ecosystems reveals that they carry memory. The material remains of foundation species can shape resilience, recovery, or collapse for decades in a changing climate. www.science.org/doi/10.1126/...

Legacies of foundation species shape life after death

The dead remains of habitat-forming organisms can have powerful influences on the resilience of the ecosystems they inhabit.

Rainfall intensity matters as much as how much rain falls. New in Nature: Corey Lesk and I show that daily-scale concentration of precipitation dries the land over the long-run, an effect as strong as total precipitation is climatological wetting. Paper here: www.nature.com/articles/s41...

More concentrated precipitation decreases terrestrial water storage - Nature

Concentration of precipitation in large events decreases land water availability, and this effect will further increase with a future warming climate.

New paper from our lab, led by Leah McTigue We reviewed 40+ years of research on drought affects on wildlife: 66% of single-species responses were negative, only 2% positive. As droughts intensify under climate change, wildlife are in trouble. 🌍🌐🧪 📄 onlinelibrary.wiley.com/doi/10.1111/...

Global Trends in Drought Impacts on Wildlife—A Review

We reviewed peer reviewed literature pertaining to instances of anomalous drought (any drought event that deviates from standard conditions (e.g., dry season) when compared to a long term average) an...

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.
