Taxon specific reporting
Describe the different methodologies for collecting your taxon.
Ardistomines are Carabid beetles. They are predators of other small arthropods and have nocturnal habits. Some species live in swamps, others in wet mountain forest or others just in places near to water corps.
Direct collecting: Preferable, a lot of information about natural history is obtained. During day they can be collected digging on soil or sieving leaves litter in very humid places. At night they can be seen strolling on ground or on standing vegetation looking for prey
Traps: Use of UV light traps is very effective but only for winged species. Pitfall traps are useful for leaves litter inhabit species.
Larvae (three instars): Have to be collected directly on its habits; some individuals have to be reared to adult to identify the species. Some times we have to rear adults, get the eggs to obtain larvae.
Describe how to preserve the collected specimens for taxonomic purposes.
Adults: Are killed in alcohol or using a killing jar with a poisonous gas. Before mounting, death bodies are softened and cleaned in hot water with a soft detergent (preferably with antifungal properties). Once dried are glued (water soluble glue) to a rectangular card board (European method) or a tip of a triangular card board (American method). Board is pined together with labels.
Larvae: Are killed in a distending solution (AGA solution: alcohol, dest. water, glycerine and acetic acid). After 24 hrs are preserved in alcohol 90°
Genitalia: Are preserved in glycerine in a microvial pined together with exemplar.
Describe how to curate a collection.
In tropical conditions, entomological collections are subjected to highs levels of temperature and humidity as well as notable variations of both parameters. So, management policies demands a particular point of view
Adults: When pinning, white pins must be choosing to avoid rusting. Labels should be printed in acid free paper. Boxes must close accurately permitting isolation from exterior. Metallic cabinets are preferable to avoid termite’s attacks.
Describe how your collection will be made accessible for other scientists by means of a relational database.
Actually I’m working in the design of the Cuban Carabids Data Base. The first objective is to get all information as possible available to work with. It would be important to build a standard DB structure useful not only for carabidologists but also for other entomologists. Once most of information will be inside, this DB would be accessible for other interest persons.
Preliminary draft of the Cuban Carabids DB relationships:
Describe in detail the taxonomic characters at the different hierarchical levels (e.g. on order level, family, genus, species) and use this information to describe in detail one species.
