Fish Research in Laguna de Masaya

The Masaya volcanic complex, lying just north of Apoyo, also contains a lake full of fish-and very interesting fish! The FUNDECI/GAIA research team are executing a study of the Midas cichlid species complex in Lake Masaya, in search of evidence that sympatric speciation has also occurred in this lake, as has been demonstrated in Lake Apoyo.

Here is Maarten Hogenkamp, fishing in Laguna de Masaya. And take another look at the foreground!!!! Yes, that is trash. This lake is severely damaged by solid waste and liquid waste from the municipalities of Masaya and Masatepe. Nonetheless, the lake has fish, and very interesting ones!

Here, Lorenzo hauls in a juvenile Midas cichlid by harpoon, and passes it off to Jeffrey McCrary of FUNDECI/GAIA while Erico from the Masaya Volcano National Park looks on.

Some of the catch: a probable new species! FUNDECI/GAIA is working with Jay Stauffer from Penn State to describe new species in Lake Masaya.

And yes, fishing also means.... repairing nets, and getting ready for the next round.

Lepidoptera!

Yes, butterflies can really look like that! It is Morpho helenor montezuma, a common butterfly in Laguna de Apoyo Nature Reserve. We completed the first phase of our studies on the butterflies and moths (members of the order Lepidoptera) earlier this year (2010), concluding with the publication of a listing of 220 species of butterflies and moths, of which 116 are new reports for the reserve, and 25 are new reports for Nicaragua. We are continuing with special effort placed on the monitoring of moths. Little is known about most groups of tropical moths.

The above moth is a typical example of the moths we are encountering in our present phase of study. We can not yet identify it or most of the moths we are capturing, but we are developing a database and slowly identifying the species in collaboration with experts in the field. Below are photos of another "unknown" and our light trap in action.

We have a reference collection of butterflies and moths on display for the public in Estacion Biologica: Our current lines of Lepidoptera study involve light traps for the moths, and fruit traps for butterflies of the family Nymphalidae (brushfoots). Would you like to work with us on butterfly and moth field studies? Please contact us! We have needs for volunteers, students, interns and collaborating scientists.

Gecko whoopee

The Asian house gecko (Hemidactylus frenatus) is a recently introduced species in Nicaragua. The Nicaraguans call it perrozompopo, along with the native gecko species. It is now found in practically every house in the country, including in Estacion Biologica in Laguna de Apoyo Nature Reserve. This nocturnal species gives hours of fun just watching them under lights as they dart after insects on the ceiling, sticking to practically any surface with their paws. The following pictures suggest just how they got to be so numerous in Nicaragua, so quickly.

Another species discovery in Lake Apoyo

Lake Apoyo now officially contains six endemic species of fishes, all close relatives of the Midas cichlid (Amphilophus citrinellus). The most recent two discoveries were published in the August edition of Proceedings of the Biological Society of Washington. The two new species are Amphilophus globosus and Amphilophus supercilius. The first discovered in Lake Apoyo in this group was the arrow cichlid, Amphilophus zaliosus, discovered by George W. Barlow, in 1976. The arrow cichlid was recently categorized as Critically Endangered on the IUCN Red List. We expect that most of the other five species in this lake face equal or greater extinction threats as the arrow cichlid, according to the results to date from population monitoring conducted by FUNDECI/GAIA in Lake Apoyo.

Here is a picture of Jay R. Stauffer, Jr., holding a copy of the Proceedings of the Biological Society of Washington, in which the descriptions of the latest two species to be discovered were published. The journal graced its cover with photos of all six known species found in Lake Apoyo.

Photos on the cover of this journal were provided by Ad Konings, Topi Lehtonen, and Matthias Geiger.

Improvements and repairs in the local rural school

Escuela Luis Alfonso Velasquez School Improvement Project 2010

The Laguna de Apoyo Biological Research Station "Estacion Biologica" coordinated and financed repairs and improvements in the Escuela Luis Alfonso Velasquez. This school attends the educational needs of 50 children who live in Laguna de Apoyo. Thanks especially to Christine Bruxer for her fundraising for this worthy project!!! The project budget ran just under US$1000.00. Not bad for a year of financial crisis.

This was the letrine. A three-seater. The termites had destroyed the wood structure, and the paint, well, you can see for yourself. The doors would no longer work at all. We adjusted the doors, changed the structural beams, applied anti-termite treatment, and painted the entire thing.

Almost the entire school interior and all of the exterior was painted with an oil-based paint. There is a well on the property which had long ago gone dry. We dug it an additional 4 meters and then placed a submersible pump in it, and sealed the top with a large reinforced concrete top with a heavy duty padlock.

Believe it or not, someone is down there!!! What a job. The parents, CPC, and other members of the community did an awesome job. The result of all this well rehabilitation:

We are happy to help to improve the lives of the poor children in Laguna de Apoyo Nature Reserve! Every child deserves a good education and a happy childhood.

FUNDECI/GAIA has performed several projects with the Escuela Luis Alfonso Velasquez, including a donation of a library for the children. Would you like to volunteer with FUNDECI/GAIA? Please contact us!
