I was scheduled to give a talk on Palestine at a student conference at @notredame.bsky.social. The University rescinded my talk a week in advance citing an extremely flimsy excuse. It is truly disgusting. Attached is the letter I received and my reply, link below...
Dear Dr. Abdelhadi,



The Keough School of Global Affairs, which houses the Kroc Institute for International Peace Studies, recently learned of your keynote speech at their student conference next weekend. The University of Notre Dame requires that all events or lectures related to Israel/Palestine have ND Police security and planning.  We were unaware of your planned lecture, and since this conference overlaps with two other annual events on campus, we cannot provide security at short notice. For this reason, we respectfully request that you do not participate in the conference. The Kroc Institute will honor any honorarium that was awarded for this event. We apologize for any inconvenience. 



Sincerely,

Mary Gallagher

Tracking Federal Cuts Mapping Project
This form allows you to contribute to the Tracking Federal Cuts Map with local stories about how the cuts are impacting your community. 

The goal of this is to better inform the public about the impact the firings of civil servants, withdrawal of funding, and termination of programs may have on everyday Americans across every state.

The intent of this project is informational. With things moving so fast on so many levels, it is hard to know how changes made in Washington, D.C. will impact us. We hope this map will help put a face to these changes. 
We are a group of grad and PhD students working on collecting stories from across the country and need your help!

Yes, it's not obvious why that is. It could be that predictability of downstream conditions is lower, that downstream passage is restricted, and/or that cues to initiate downstream movement are absent in low flow years. Hope to learn more about it with future studies.

Interestingly, we found no evidence that non-natal rearing is driven by competition in the natal habitat, as previous earlier work indicated, suggesting instead that non-natal rearing is volitional. (7/8)

Importantly, non-natal rearing was not expressed during very flow years, suggesting that as drought becomes increasingly common with global climate change, impacts on fish may be compounded by losses of critical phenotypic variation. (6/8)
Scatter plot with mean daily flow (cfs) on the x axis and the proportion of fish non-natal rearing on the y axis, showing a non-linear increase in the proportion of non-natal rearing as flow increases.

Hank Baker @hankbaker.bsky.social · 25/02/2025
This effect may be mediated by differences in growth rate and emigration timing between groups. The non-natal rearers have more variable growth rates (only 1 yr of data), and more variable but earlier emigration timing than natal rearers. (5/8)
Raincloud plot with rearing strategy on the x axis and water year day of emigration on the y axis showing more variable but earlier distribution of emigration timing for non-natal than natal rearing fish. Raincloud plot rearing strategy on the x axis and daily growth (mm) on the y axis showing more variable distribution of growth rates (with higher maximum and lower minimum) for non-natal than natal-rearing fish.

Hank Baker @hankbaker.bsky.social · 25/02/2025
This distinct, but somewhat subtle, form of phenotypic variation had important effects on population dynamics: The early downmigrants (non-natal rearers) returned as adults at a higher rate and with 1.6x greater stability through time than their natal rearing counterparts. (4/8)
Proprtional bar graph showing that natal rearing is more common among juvenile salmon, but that non-natal rearers comprise a greater proportion of adult returns. Graph with rearing strategy (natal, non-natal, and both together) on the x axis and stability of adult returns on the y axis showing that non-natal rearers are more stable than natal rearers by 1.6x, which makes the aggregate population more stable by 1.4x relative to the natal rearing group alone.
