Objectives
1. Gather life history data to inform F3 model parameterization:a) fishesb) invertebrates
2. Use existing data to determine scales of decorrelation in larval settlement:a) spatial b) temporal

Focal species:
- Kelp bass (Paralabrax clathratus)- Kelp rockfish (Sebates atrovirens)- Cabezon (Scorpaenichthys marmoratus)- Urchins (S. purpuratus; S. franciscanus)- Abalone (Haliotis rufescens)- Lobster (Panulirus spp.)

Progress to date:data gathered
• Habitat
• Duration of releases
• Realized dispersal distance
• Spatial scale of releases these data don’t seem to exist for most species relevant to F3

Progress to date
- Initial (de-)correlation analyses explored
- Some data quality and analytical issues need resolution
- Currently revising these analyses to allow for more reliable, robust conclusions

Planned work
Incorporate new data:
- Latest (2004) PISCO data
- Other datasets (if possible) (Gaylord; VanTresca; Roberston)
![Page 28: Scales of larval settlement in marine fishes and invertebrates Elizabeth Madin, Jenn Caselle and Robin Pelc 26 May 2005.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d395503460f94a125de/html5/thumbnails/28.jpg)
Planned work
New analyses:
- More robust (de-)correlation analyses
- Apply spatial statistical techniques
(e.g., semivariograms/covariograms, kriging(?))
![Page 29: Scales of larval settlement in marine fishes and invertebrates Elizabeth Madin, Jenn Caselle and Robin Pelc 26 May 2005.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d395503460f94a125de/html5/thumbnails/29.jpg)
Planned work: Spatial stats
![Page 30: Scales of larval settlement in marine fishes and invertebrates Elizabeth Madin, Jenn Caselle and Robin Pelc 26 May 2005.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d395503460f94a125de/html5/thumbnails/30.jpg)
Planned work
Further data exploration: - analogous analyses for SST data
- partitioning PISCO dataset by year (i.e., to filter out interannual variation)
- prewhitening (i.e., to filter out large scale climatic variation)
- examine potential larval/oceanographic interactions (spatial; temporal)
![Page 31: Scales of larval settlement in marine fishes and invertebrates Elizabeth Madin, Jenn Caselle and Robin Pelc 26 May 2005.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d395503460f94a125de/html5/thumbnails/31.jpg)
Planned work
Comparison with results of related studies:
- Myers et al. (1997)
settlement decorrelation (fishes); global
- Field and Ralston (in review)settlement decorrelation (fishes); west coast
- Broitman et al. (in press) recruitment variability (intertidal inverts); SCI

Points for discussion
- Calculation of ‘non-linear’ PISCO pairwise site distances:
- weighting by current/flow data?
- other methods?
- Suggestions of other useful analyses?
![Page 34: Scales of larval settlement in marine fishes and invertebrates Elizabeth Madin, Jenn Caselle and Robin Pelc 26 May 2005.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d395503460f94a125de/html5/thumbnails/34.jpg)
Conclusion
- PLD and other life history characteristics may influence the scales of spatial and temporal decorrelation in larval settlement
- Spatial decorrelation plots may inform the probability distribution (kernel) of larval dispersal in specific regions
