Variability in the vertical distribution and advective transport of eight mesozooplankton taxa in spring in Rivers Inlet, British Columbia, Canada
Bibliographic record
Abstract
Zooplankton vertical distribution data and velocity estimates from a hydrodynamic model were employed to determine zooplankton daily exchange during four cruises conducted from March to June 2010 in Rivers Inlet, a fjord in central British Columbia, Canada. Zooplankton transport rates varied temporally, being fastest in March when water velocities were highest. The active vertical movement of the zooplankton interacted with the vertically sheared flow field to influence zooplankton advection. Surface dwelling plankton such as Acartia longiremis and larvaceans experienced the highest advection losses of −0.4 and −0.5 day−1, respectively. In contrast, maximum advection losses of Paraeuchaeta elongata, a deeper dwelling copepod, were an order of magnitude lower, at 0.04 day−1. Transport rates varied by stage, extent of diel vertical migration and timing of ontogenetic migration. Advection rates were lower than literature-derived egg production rates, but comparable to literature-derived mortality rates. We suggest that advection may be a significant driver of population dynamics in years with similar rates of population growth. We also stress the importance of determining advection rates to obtain accurate estimates of vital rates.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
