Hi Diana,

 

Yes, that is possible. In the Run Larval Dispersal Simulation (2012 Algorithm) tool, under Additional Options, there is a parameter called Patches That Disperse Larvae. This is where you can list which patches you want to release larvae. If you do not specify anything, larvae will be released from all of them. There is also the Patches That Larvae Can Settle On parameter. By using those parameters together, you can simulate the case where larvae are released from certain locations but are not allowed to settle there. This might be useful when simulating fish that spawn in aggregations at locations that are not suitable for settlement.

 

Best,

Jason

Thank you very much!

 

I find this tool very useful. I will cite it properly on any publication that may come from my thesis

 

I have been checking the information in the link

and I would like to ask  another question that comes to me when reading the website:

is there a possibility that larvaes be released from specific patches in the raster ? in order to simulate spawnning agregations of fish species?

 

Thank you in advantage

Best regards,

Diana Carrillo

Dear Diana,

 

Your project sounds interesting. I’m sorry we have not updated the blog entry to discuss that step. You can view the documentation of that tool here. It creates three outputs:

 

1.   A survivorship curve.

2.   A time series of rasters showing the density of larvae as the simulation progresses. You can animate these with ArcMap.

3.   A shapefile giving the connectivity matrix. You can use that to produce maps like the one attached, or to perform further analysis.

 

Best regards,

 

Jason

 

 

Dear Professor,

 

My name is Diana Carrillo I am working on a master´s degree project wich aims to model de connectivity of  fish and coral species in the Gulf of Mexico, I am interested on using the Marine Geospatial Ecology Tools for that purpose. I had reviwed the website http://mgel2011-kvm.env.duke.edu/mget/2016/03/31/new-larval-connectivity-modeling-tools/

but I would like to know if there is more information, especially about the section "Visualize the results"

 

With regards,

Diana Carrillo
