International Journal of Climatology, EarlyView.Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal

The most threatened plants receive the least scientific attention
PLANTS, PEOPLE, PLANET, EarlyView.Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal
