ALT Blog figure caption: Variation in analysis outcomes (standardized effect sizes) due to analyst decisions in two datasets (A: effects of number of siblings on blue tit nestling growth; B: effects of grass cover on Eucalyptus regeneration). Each teal triangle and horizontal bar represent the effect estimated by a different analysist (triangle) and the uncertainty around that estimate (the range of horizontal bars corresponds to the 95% confidence interval). The black circle and dashed vertical line indicate a mean estimate considering all analyses. The solid black vertical line demarcates effect size of 0, indicating no relationship between the test variable and the response variable. Standardized effect sizes <0 (left of solid black vertical line) indicate negative effects, e.g., blue tits with more siblings grow less than those with fewer siblings. Effect estimates with confidence intervals overlapping 0 are indistinguishable from no effect. Reproduced from Gould, et al., 2025.

The massive Northern California flood of 1955 remains the deadliest to hit the Yuba City and Marysville region. 38 were killed, 280 homes were destroyed and over 1500 were damaged. The Shanghai Bend on the west levee of the Feather River, about one mile south of Yuba City was breached around midnight on Christmas Eve, and a wall of water cascaded into Sutter County, which forced thousands of residence to evacuate their homes.
