Good stuff - thanks for posting!

Crater lakes provide a unique laboratory for understand speciation and evolution.

Has there been any further work since this was published to further understand the relationships among the Amphilophus in the lakes?

Also, anyone know how introduced Tilapia are impacting these habitats?

Matt, look up "Tilapia (Teleostei: Cichlidae) status in Nicaraguan natural waters" by Jeffrey K. McCrary, Brian R. Murphy, Jay R. Stauffer Jr., Sherman S. Hendrix (Environ Biol Fish (2007) 78:107–114). If you can't get it I can email it to you.

"Abstract:

We surveyed the watersheds covering more than 80% of the surface area of Nicaragua, and review the history of deliberate introductions and unintentional invasion of tilapias, Oreochromis spp., into the freshwater of Nicaragua. The species have become widely established, with a range of negative consequences for the rich natural fish fauna of this Central American country. Tilapias compete directly with native cichlids in a number of ways, and have also supplanted native species as food fish in local markets. We suggest that introduced tilapias may have been responsible for the outbreak of blindness in native cichlids. We make recommendations on the management of these exotic species and on further introductions."

You should also be able to look up any paper that cites the paper Miguel posted.
