Weak and species-specific morphological change in Atlantic Forest birds across two decades of warming doi.org/10.32942/X28...
Modelling sampling turnover more than halves the estimated wing-length decline. (A) Within-species-centred wing length over time across 8,478 records from 72 species. The dashed line represents the baseline model (−1.8 mm/decade); the solid line and band represent the fully adjusted model (−0.7 mm/decade, 95% CrI spanning zero). Inset displays wing records per year. (B) Effects of each capture year on wing length from the baseline (open circles) and fully adjusted (filled circles) models with year as a factor, centred on the record-weighted mean year, with 95% confidence intervals (glmmTMB REML, pooled over 50 phylogenetic trees); the fitted linear trends of panel A are repeated. Unlike raw annual means, these intervals account for the clustering of records within species, contributors and municipalities. Linear trends and their bands are posterior means and 95% credible intervals pooled over 20 phylogenetic trees.

🚨Elsevier forces out Games and Economic Behavior (GEB) Editor, entire editorial board has resigned, current board only handling new submissions until Nov. 14 #econsky
    Dear Advisory Editor of GEB
    We are very sorry to be the bearers of bad news for GEB.
I learned from Elsevier on Wednesday July 28 that, contrary to my expressed willingness to continue, my 3-year contract will not be renewed.
    "Moving towards a closer alignment with Elsevier strategic priorities and publishing policies" was offered as the motive for this decision. Requests for explanations, first by me, then in a collective letter by the other six Editors, were dismissed by Elsevier which simply reaffirmed its legal power to make such decisions.
    Elsevier then started precipitously its own search for new Editors without input of the Editorial Board.
    By Friday August 14 all seven Editors have sent their resignation, requiring a 3-month advance notice.
    Therefore, we will continue to manage as before the papers currently under review and the new submissions until Saturday November 14. After this date we will only complete the evaluation of papers still waiting an editorial decision.

Most people are not adding in prep manuscripts to their CV because they think it will be viewed as a publication. They are doing it to show you what they are actively working on, and might even be available by the time applications are reviewed. You can simply ignore this info if you want!
