Can we estimate the period and quality-factor of the Chandler wobble using only the observed polar motion data?

open access: yesEarth, Planets and Space
The clear ~ 6-year beat in the polar motion data has allowed us to consider the Chandler period (P) as ~ 1.2 years, albeit approximately, from solely the observed polar motion data.

Strawberry Crown Plugs Provide Flexibility and Improved Performance in Cold Climate Plasticulture Production

open access: yesAgronomy, 2021
Annual plasticulture strawberry production has not been adopted as rapidly in cold climate regions as has occurred in warmer production areas due to uncertainty about potential benefits. Recent trials have demonstrated the potential of regionally adapted

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
