Mongolia Expedition 2002

Section Responsible for Processing (Top)


Significance (Top)

Very little is known about the crustacean fauna of Mongolia. This expedition sampled previously unexplored areas in order to better understand the biodiversity of freshwater invertebrates of Mongolia.
More data about this collection are at the Mongolia Expedition website.

Background (Top)

The Mongolia Expedition was funded by National Science Foundation grants DEB-BE-0120635 and DEB-PEET-9978193 awarded to Dr. Joel W. Martin, Curator of Crustacea, Natural History Museum of Los Angeles County. The trip was organized by Dr. Regina Wetzer.

Collection Location and Dates (Top)

Samples were collected from Töv, Dundgov', Ömnögov', Bayankhongor, Arkhangay, and Övörkhangay aimags of Mongolia (geographic coordinates for each site are included as part of the label data). Freshwater habitats including temporary ponds, lakes, rivers, streams, and underground springs from various ecosystems such as desert, desert steppes, forest steppes, and mountainous regions, were sampled. The dates of the expedition were from 18 August to 3 September 2002.

Taxonomic Contents (Top)

The collection consists primarily of ostracods, copepods (and other meiofauna), conchostracans, anostracans, notostracans, insects (aquatic and terresterial), spiders, leeches, various gastropods, and nematomorphs.

Documentation (Top)

Letters of invitation and permits are on file in the Registrar's Office. See the Mongolia Expedition website for physical descriptions of collecting sites.

Description of Collection (Top)

The specimens were originally fixed and preserved in 95% ethanol. Upon return to the Crustacea Lab the original preservative was replaced with fresh 95% ethanol. Currently the collection is located in the Marine Biodiversity Processing Center's Collection room.

Collection Inventory (Top)

The collection consists of approximately 114 lots.

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.
