Hypoxia effects on fish populations: model predictions under fixed vs. dynaimc oxygen environments

dynaimc oxygen environments category goes here and here Predicting marine ecosystem responses to environmental variation: Now is the time to merge bioenergetics and movement ecology Kenneth Rose Horn Point Laboratory Cambridge, Maryland Today • Organisms will move in response to climate change • Progress on movement – Observations – Modeling • Status of bioenergetics • Need and opportunities for m. [...] Behavioral Ecology 26: 877-884 Progress: Movement Modeling • Many approaches have been proposed – X(t+1) = X(t) + Vx(t) – Y(t+1) = Y(t) + Vy(t) – Z(t+1) = Z(t) + Vz(t) – Determine the cell • Quite confusing because of non- standard descriptions and terminology for Vx, Vy, and Vz – Random walk – Run and tumble – Event-based – Restricted-area – Kinesis – ANN A movement ecology framework that integra.

[...] Disconnect • Movement cues – Sometimes projected growth – Often temperature or other habitat variable • Selection (optimization) of speed, direction, or destination • Trajectory (journey) • Bioenergetics consequences • Routine type movement maybe OK but not for GCC 47 Necessity or Opportunity • Merge movement with the bioenergetics • Consistency (two-way) • Journey and destination affect bioenerge.
