Mesozooplankton grazing and primary production: An alternative assessment

In a recent paper in the journal, Calbet (2001) describes the analysis of data on primary production and mesozoo-plankton grazing from a wide variety of marine ecosystems. The somewhat surprising result of Calbet's analysis is that, ''The slope of the log-log relationship between ingestion rates and PP was significantly Ͻ1, indicating a decline of relative importance of mesozooplankton grazing ...

Radically Questioning the Principle of the Least Restrictive Alternative: A Reply to Nir Eyal; Comment on “Nudging by Shaming, Shaming by Nudging”

In his insightful editorial, Nir Eyal explores the connections between nudging and shaming. One upshot of his argument is that we should question the principle of the least restrictive alternative in public health and health policy. In this commentary, I maintain that Eyal’s argument undermines only a rather implausible version of the principle of the least restrictive alternative and I sketch ...

Comment to the Letter to the Editor: Subjective Symptoms Related to GSM Radiation from Mobile Phone Base Stations: a cross-sectional study In reply to the comments by Seyed Mohammad Javad Mortazavi

Limnol. Oceanogr., 44(6), 1999, 1370–1380

The phytoplankton in warm oligotrophic regions of the open oceans is dominated by ,2-mm cells too small for efficient direct consumption by mesozooplankton. However, these primary producers are hypothetically linked to higher trophic levels via the cascading impacts of mesozooplankton grazing on intermediate consumers. To assess the magnitudes of these indirect trophic linkages, grazing experim...

Modeling responses of diatom productivity and biogenic silica export to iron enrichment in the equatorial Pacific Ocean

[1] Using a three-dimensional physical-biogeochemical model, we have investigated the modeled responses of diatom productivity and biogenic silica export to iron enrichment in the equatorial Pacific, and compared the model simulation with in situ (IronEx II) iron fertilization results. In the eastern equatorial Pacific, an area of 540,000 km was enhanced with iron by changing the photosynthetic...
