Costa Rica, Cahuita Collection 19868-1987

Section Responsible for Processing (Top)


Significance (Top)

The specimens in this collection come mostly from Atlantic Costa Rica and were collected by R.C. Brusca, G. Hendler, R. Wetzer, P. M. Delaney, and R. W. Peck between 1986 and 1987. This project was supported by a grant from the Weiler Foundation. Dr. M. Murillo of the Universidad de Costa Rica in San Jose coordinated this survey of the only coral reef in Atlantic Costa Rican waters.

Background (Top)

During the 1980s Parque Nacional Cahuita was heavily impacted by deforestation, logging, banana and coffee plantations to the north of the park. Runoff resulted in heavy siltation and alteration of the physical and biological structure of the reef.

Numerous publications by the above listed participants as well as other American and Costa Rican scientists have resulted from this survey.

Collection Location and Dates (Top)

Collections are marine - mostly intertidal to SCUBA diving depths in the areas around Punta Cahuita, Puerto Vargas, and Limon. Additional collections unrelated to the Cahuita project were made in Nicaragua, Pacific Costa Rica, and Pacific and Atlantic Panama. The Cahuita reef was visited quarterly over a 2 year period.

Taxonomic Contents (Top)

These collections contain benthic invertebrates. Collecting emphasized echinoderms (Hendler and Peck) and peracarid crustaceans (Brusca, Wetzer, and Delaney). The unsorted material contains mostly crustaceans, gastropod molluscs, forams, etc.

Documentation (Top)

The station data for the remaining unsorted lots are available as a PDF under "Collection Images." Accession numbers F.P.2.86-6, F.P.2.86-7, F.P.2.87-1, F.P.2.87-3, and F.P.2.88-2.

Description of Collection (Top)

This is a wet preserved 70% ethanol collection. This collection was fixed and preserved in ethanol in the field (not exposed to formalin). The remaining unsorted lots are stored in the LACM Polychaete Collection Room.

Collection Inventory (Top)

There are ca. 30 jars representing 17 stations. The lots are contained in 4 to 32 oz. jars. Excess sand and silt has been removed and all ethanol was replaced February 2004. The remaining (estimated to have been originally ca. 150 lots+) material from this collection has been sorted, identified, and incorporated into the LACM echinoderm, polychaete, mollusk, and crustacean research collections.

Specimen Condition (Top)

Date 4: New alcohol needed immediately (specimens will otherwise be irreparably damaged) 3: Containers need to be 'topped off' 2: New alcohol needed within next 6-12 months 1: No curation needed at present

Container Condition (Top)

Date 4: Immediate short-term (less than 5 years) storage container replacement needed. Present containers are inadequate. Curate in the short-term with plastic buckets, whirltop bags, or similar. 3: Specimens contained in museum-grade long-term (greater than 5 years) storage containers. Jars need new closures (e.g. replace Bakelite and metal lids). 2: Transfer to museum-grade long-term storage containers. Replace or transfer to new jars and glass vials, replace cotton and closures. 1: Containers are museum-grade and meet highest curation standards.

Label Condition (Top)

Date 4: New labels needed immediately (original labels in poor condition, paper torn/worn, legibility poor). 3: New labels needed within next 1-2 years (original labels beginning to wear, pencil writing fading, low quality paper was used). 2: New labels needed are as a result of curation and accretion of collection. 1: No new labels needed at present.

Label Content (Top)

Date 2: New label or additional label needed because original label data is incomplete and supporting documentation provides additional collection data which greately enhances significance and value of each lot. 1: Label content complete. All collection data are contained on label.

Most of this collections had been sorted, identified, and incorporated into individual collections a long time ago. It is estimated that 11-12% (17 lots) remain as unsorted material in the MBPC Collection Room. There is also a unknown number of lots (but less than 50) in the Crustacea Collection Room. The 100% "not identified" is what remains to be processed.
