Biologist | San Marcos, Texas Office

Job Description:

BIO-WEST, Inc.’s San Marcos Office is seeking a biologist with a strong background in aquatic ecology with a focus on macroinvertebrates.  This is a full-time assignment that will consist of approximately 40/40/20 (Laboratory/Field/Office) involving endangered aquatic beetle applied research in a federal laboratory, in addition to fish, freshwater mussels, eels, and invertebrate work throughout Texas and beyond.  The primary laboratory research 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) as part of the Edwards Aquifer Habitat Conservation Plan (EAHCP). These species are a crucial component of the EAHCP and a more thorough understanding of basic life-histories and habitat information is needed to assess long-term biological goals and future plan development. These are small animals 2 – 3 mm in length, but larvae may be less than 1 mm in length.  The fieldwork component will focus on endangered species sampling in spring-fed central Texas systems, along with fish, mussels, American eels, and aquatic macroinvertebrate investigations throughout Texas, the southeastern U.S. and intermountain west.  ]
