Biologist/Technician | San Marcos, Texas Office

Job Description:

BIO-WEST, Inc.’s San Marcos Office is seeking a biologist with a strong background in aquatic arthropod biology, particularly aquatic beetles. Primary work will be based on studies of the endangered Comal Springs riffle beetle (Heterelmis comalensis) and Comal Springs dryopid beetle (Stygoparnus comalensis) in coordination with the US Fish and Wildlife Service (USFWS) and the Edwards Aquifer Authority. These species are a crucial component of the Edwards Aquifer Habitat Conservation Plan (EAHCP) and a better understanding of basic life-histories and habitat information is needed in order to meet the long-term biological goals of the plan. These are small animals 2–3 mm in length, but larvae may be less than 1 mm in length.

The successful applicant will provide technical support to the project manager/principal investigator with ongoing studies related to improving captive rearing of beetles at a USFWS facility and with field studies related to monitoring and estimating wild population size. A highly motivated candidate may have opportunities to conduct their own research within the framework of the existing studies. Additionally, it is anticipated that the successful applicant will work on other BIO-WEST ecological projects as appropriate. Knowledge or experience working with herps, crayfish, mussels, birds, and/or aquatic plants is extremely advantageous to support ongoing and future BIO-WEST projects.
