Data from: Thicker shells reduce copepod grazing on diatoms

Josephine Grønning, Fredrik Ryderheim & Thomas Kiørboe
The diatom frustule provides partial protection against copepods, yet we do not know the mechanism behind the reduced grazing. We used direct observations of copepod-diatom interactions to compare rejection frequency and prey-handling times of diatoms with different degrees of silica content in three differently sized species. We compared rejection frequency and prey-handling times of thick- and thin-shelled cells of the diatoms Cyclotella cryptica, Thalassiosira weissflogii, and Ditylum brightwellii. We found that for all three species,...

Greenland mass trends from airborne and satellite altimetry during 2011–2020

We use satellite and airborne altimetry to estimate annual mass changes of the Greenland Ice Sheet. We estimate ice loss corresponding to a sea-level rise of 6.9±0.4 millimeters from April 2011 to April 2020, with the highest annual ice loss rate of 1.4 mm/yr sea-level equivalent from April 2019 to April 2020. On a regional scale, our annual mass loss timeseries reveals 10-15 m/yr dynamic thickening at the terminus of Jakobshavn Isbræ from April 2016...

Deriving population scaling rules from individual-level metabolism and life history traits - Code and Data

Rémy Denéchère, P. Daniël Van Denderen & Ken Haste Andersen
Individual metabolism generally scales with body mass with an exponent around 3/4. From dimensional arguments it follows that maximum population growth rate (rmax) scales with a -1/4 exponent. However, the dimensional argument implicitly assumes that offspring size is proportional to adult size. Here we calculate rmax from metabolic scaling at the level of individuals within size-structured populations while explicitly accounting for offspring size. We identify four general patterns of how rmax scales with adult mass...
